Production Transcript for Ep42 The Space Launch System Part.2.mp3 Gary Jordan (Host): Houston, we have a podcast. Welcome to the official podcast of the NASA Johnson Space Center, Episode 42: The Space Launch System, Part 2. I'm Gary Jordan, and I'll be your host today. So in this podcast, we bring in the experts -- NASA scientists, engineers, and astronauts -- all to let you know the coolest information about what's going on right here at NASA. So today, we're talking about the most powerful rocket since the Saturn V moon rocket, NASA's Space Launch System. We've got two guests from the Marshall Space Flight Center in Huntsville, Alabama here with us today to tell us about the rocket, the payloads it can carry, and where it will go. Spoiler alert: It will bring people, big stuff, and little stuff all farther than we've ever gone before. See, I did it again. You had a second chance for Part 2, and you blew it, Gary. If you're slightly confused, it's because this is Part 2 of our two-part episode on NASA's Space Launch System. There's still some good stuff in here, but if you want the full story, just go back and listen to Part 1. So continuing our conversation with us today are David Smith and Paul Bookout. David is the Vice President for Advanced Programs and Victory Solutions in Huntsville, Alabama. He has a long career in aerospace engineering and is a subject matter expert on rocket architecture and how payloads will fit into the rocket. He wrote the SLS Mission Planner's Guide, which gives payload developers a general idea of the capabilities of the rocket and some technical specifications so they can determine how their payloads might fit inside. He looks after the big payloads. Our other guest today is Dr. Paul Bookout, EM1 Secondary Payloads Integration Manager, who manages the integration of five CubeSats in the giant rocket as well the avionics that will control the deployment of all 13 small satellite payloads on the first mission of SLS and Orion called Exploration Mission 1, EM1. He spends his time managing the little payloads, not much bigger than a shoebox, on a skyscraper-sized rocket. So we're going to talk about just how powerful this monster rocket is, its unique capabilities, what it'll be used for, where it is in its development, its first mission with the Orion crew vehicle, and then look ahead to the future to the Moon, to Mars, and throughout the solar system. In this particular episode, we talk a lot about propulsion on this rocket, especially comparing solid and liquid fuel for the rockets. So at a very high level, the key differences are cost and control. Solid rocket fuel systems are generally simpler in design, cost effective, and they produce a large amount of thrust. But once the fuel is ignited, you can't really turn it off. Liquid fuel systems provide more flexibility. You can regulate the thrust through system throttle settings, but liquid fuel systems can be more costly. Very smart engineers have assessed the best way to use these two fuels and, for the SLS, they've come up with a combined design of solid and liquid fuel system. Solid fuel boosters and liquid fuel, the main engines to work in tandem to get you off the ground and moving fat, and then liquid fuel carries, or the liquid fuel engines will carry you where you need to go. So we're go for launch with Mr. David Smith and Dr. Paul Bookout for the Space Launch System program, T minus 5, 4, 3, 2, 1, 0, and liftoff of Episode 42 of Houston We Have a Podcast. Boom, nailed it. [ Music ] Okay. Paul and David, thanks for sticking around. This is going to be Part 2. We're sort of continuing our conversation, and we were talking a little bit during this I guess intermission, but one of the main things that we forgot to touch on was it takes eight minutes to do the first part of this launch. That's the solid rocket boosters and the core stage-- David Smith: Ignition to disposal of those stages. Host: Yes. Yeah, but I guess up to this point, all you need is some sort of injection burn, and you can pretty much go anywhere in the solar system. Is that right? David Smith: That's right. >> So it just depend, you just define what kind of injection burn, and you can go anywhere. David Smith: Well, it's the injection burn, and then the characteristic energy, which is the acceleration to get to that location. You know, it's a curve, so-- Host: Yeah. David Smith: If you go farther out, the less mass you can bring with that injection burn. So it is, it's the timing of the injection burn and the trajectory. But also, the farther away you go in the solar system, obviously, the less mass you can carry. So that's all kind of combined together. Host: That's right. And so for EM1, the injection burn is going to be translunar, right? David Smith: Correct. Host: But you can also do Mars injection burn, or Jupiter injection burn, or, like, anything after this eight minutes, it's just, you can just define it? David Smith: That's right. Yep. Host: So that's really the main thing about this vehicle is after eight minutes, you're ready to go wherever you want, and the fact that it's human rated, and the fact that you can bring really large payloads, right. I guess that, we'll start off with that. So we're building this rocket to pretty much go anywhere, but what are the sorts of missions we're looking at for the future for SLS? David Smith: Yeah, the first missions that are being considered are translunar and perhaps making something that has a, kind of a complicated acronym, LOP-G, Lunar Orbiting Platform/Gateway. What it really is is like a service plaza on a toll road. So think of Saturn V as the rocket that went out and surveyed everything and, you know, there were no roads, and it kind of established these, you know, these paths to go to the Moon, okay. Now, SLS is going to take that survey information and hopefully make this Lunar Orbiting Platform into a service plaza where, what do you get there? Well, you get a safe place for the crew. You can refuel landers that can go to the Moon. You can have a navigational way station. You can have a communication way station. You have a place for internationals to come by and make sure they got everything together before they go to the Moon. This gateway, in fact, gives you universal, total access to any spot on the lunar surface. Apollo is just equatorial. This station will give you access to any place on the Moon. So it has a lot of really great attributes, but it's a different kind of thing. Unlike the Space Station, which is purely science, this Lunar Orbiting Platform is probably going to be a lot more utilitarian and allow a lot more understanding and exploitation of the Moon and the lunar surface, which is, in fact, what we need that experience so that we can actually do the same thing for Mars. So it's three days away versus nine months away with Mars. So that, that's our first stage. It seems in the 2020's, we're going to be putting that together one piece at a time. So the first piece might be an EM2 mission that delivers a solar electric propulsion system that essentially is the way that this station keeps in its place. So it's just a little bit of impulse in this halo orbit around the Moon. You can stay there with very little power using a xenon solar electric propulsion system. The second part might be a habitation module. This isn't where the crew are going to, they're not going to live here full time. Again, it's a way station, so it's a place they can hang out, refresh themselves, get food, change clothing, who knows on their way to the Moon. Then, they're going to have an air lock that allows them to do servicing on perhaps landers and other kind of equipment that comes into that gateway. And then, also, a place for logistics modules to come to resupply this service plaza so that, for the long term, it can service people going to and from the Moon. So that's probably the first part, and that looks like that would be something that would be in the early 2020's, and that's where the current administration seems to be focusing us is on doing lunar first to be prepared for Mars later. Host: Okay. It's kind of like a small truck stop. David Smith: It is. David Smith: It is-- David Smith: Think of it as, yeah. [laughs] Yeah. And it should be kind of looked at that way as it's a way station to greater and better things, either the Moon or Mars. Host: Yeah. That's right. You can shower. You can, [laughs] you can service it. It's got a-- David Smith: Get your eggs and steak. Host: Yeah. David Smith: You know, get your car repaired. Refuel. Get some gas. Tow truck is even there to maybe save you if you have a probably on the Moon. So really, it's a good deal. It's kind of like a lighthouse and service plaza all put into one. Host: But not only will the SLS get us there. It's actually going to get the LOP-G there, right? It'll actually-- David Smith: It'll assemble it. David Smith: It'll assemble it. Host: In pieces. Now-- David Smith: Yeah. David Smith: If we were to do it the best way, instead of doing it in smaller pieces -- and by the way, it's going to do this just using the trunk section underneath the Orion. So the co-manifested payload is what these little elements of the station are going to be. If we were, if we could, it'd be best to just make one giant chunk and put in the, into a fairing, but the way I think the program is unfolding, to use crew to start with, is to bring the station in pieces that the crew can assemble at that location. Host: So going back to the previous episode, Episode 41 -- if you haven't listened to it, go back -- and that was the first part of our conversation, but going back to this co-manifested payload, we're talking about primary payloads, co manifested, secondary. What's the co manifested? David Smith: Yeah, the co manifested, again, is the ten-ton capability that is the trunk space underneath Orion that's going to fly on the Block 1B SLS. So in contrast, if you took off the Orion and its trunk space and put a large fairing on top, you get a primary payload that could be 40 tons the Moon. So it's ten tons the Moon is co manifested, or it's maybe 40 tons the Moon as a primary payload. And the secondary payloads are payloads of opportunity. They kind of fit in little, tiny spaces that are left over. They aren't filled up with other kinds of stuff. Host: And that's where Paul comes in-- Paul Bookout: Yes. Host: Right? [laughter] Paul Bookout: That's my world. Host: That's right. David Smith: So after Lunar Orbiting Platform-Gateway, one of the early missions that's been envisioned is taking a probe to the Europa, the moon, icy moon of Jupiter. What's so neat about this mission is that SLS, is we have to loft this payload and get it to Jupiter in two-and-a-half years, where a current ELV -- Atlas, Delta, even a Falcon 9 Heavy -- couldn't do that in more than seven years. So we're going to cut five years off a trip. Now, what does that mean? Well, one, it means that you're getting quicker returns to the science community. You're helping people not spend their whole career on one science mission. You have younger people come in, work on a mission, do it quicker. And if it costs $100 million a year to maintain a cadre of ground controllers watching this thing, think of the money that you're saving over time if you can eliminate five years of that mission. Plus, the risk of that hardware traveling through space. So this is a real enabler for Europa. In fact, SLS is the only vehicle that can bring it there in that kind of time. Host: Unbelievable. Is it a bigger payload because it's a, it's SLS, or is it just-- David Smith: Well-- Host: It gets it there faster? David Smith: In this case, Atlas could fly the same mass of payload, which is very large, by the way, but it would take over seven years. Host: I see. David Smith: So it had to take a whole bunch of gravity assists around the Earth and Venus to get it there where SLS can send it there directly. Now, to your point is the New Horizons mission, which was the mission to Pluto, I think it was 120-kilogram payload that was finally delivered there after like ten years. In that case, SLS couldn't get you there any faster, but it could double the payload to over 250 kilograms of delivered payload to Pluto. So it just depends on the trajectory and the position of the planets when you do this, on what value you have, but the fact you can do it quick is a unique attribute that only SLS can bring right now. Host: [laughs] Unbelievable what this rocket is capable of. And I kind of wanted to go back and kind of visit the rocket itself, where, the history of it. Where did we start with some, building some of these pieces, and kind of where are we now? So if we can just sort of start at the beginning, whenever SLS was proposed, and we're going to hammer in the first nail, I guess. It's a little bit more complicated than that, but where did this all begin? Paul Bookout: Yes. Of course, the primary design was based off of the shuttle heritage. You know, we're taking components that the shuttle used, the propulsion aspects of it -- the [inaudible] motors, the external tank, and the space shuttle main engines -- and utilizing, upgrading, making more powerful the, those components and assembling the core stage. So that's kind of where the history of where SLS is coming from. So we want to use that existing technology, again, upgrade it, make it better. Also, the manufacturing facilities that go into making these components are in existence, so we want to still utilize that, save money, save schedule to move forward with the SLS rocket. Host: Okay, and so it's kind of, that makes sense, right, because it's, you have, okay, this is a core stage that works. These are components of the shuttle that worked. Let's just sort of fit it and to meet these requirements of building a giant rocket that can take payloads anywhere in the solar system. Paul Bookout: Exactly. Host: And humans too. It's human rated, which is a huge component of this whole thing. Paul Bookout: Definitely. Host: So it's, where is it being built? Is it one location? Paul Bookout: No. Actually, overall, there's 44, over 44 states-- Host: Oh, wow. Paul Bookout: That different components are going to be, are being built in. So this is America's rocket. Host: Yeah. [laughs] Paul Bookout: So it's not just NASA's. It's being built all over. You know, there's more than 1000 contractors working on this, in addition, of course, into, in addition to NASA. The core stage, which is the prime or contractor is Boeing, they're building that in Michoud, which is outside of New Orleans. The engine prime is Aerojet Rocketdyne. They're being developed, or manufactured, or refurbished down at the Stennis Space Center. And then, when they're done, they'll be shipped to Michoud for integration with the core stage. And then, that core stage with the main engines would be sent back to Stennis for testing because Stennis is the primary testing facility for NASA-- Host: I see. Paul Bookout: For rockets. The boosters is the Orbital ATK. They're actually manufactured just north of Salt Lake City in Utah. And it's kind of ironic that the, it's very close to the Golden Spike, where the east and west railroads met when they were building the transcontinental railroad, was very close to that because the motor segments are used in the rail system to ship down to KSC from ATK, Orbital ATK out in Utah. Host: Oh, okay. All right. Paul Bookout: So-- Host: I like that. Paul Bookout: A little history there. [laughs] And the upper stage, of course, where, as Boeing ULA, which is a direct purchase from them for that. And that's being built in Decatur, Alabama. Host: Wow. All over the place is absolutely correct, so-- Paul Bookout: And again, those are just the primary elements. All the subsystems to that are spread out all over the United States. Host: So what is currently built, and then what's on the ticket to be built? David Smith: Well, right now, the core has been built three times so far. The weld confidence article to make sure that friction stir welding is appropriate because it's the world's tallest, biggest weld fixture-- Host: Oh, wow. David Smith: Down at Michoud, so we had to test that first. Then, they're building test articles. And then, the flight hardware. The test articles right now are up at Marshall, so there's this new barge -- actually, it's the same barge they used for shuttle Pegasus. They had to make it a lot longer, so they cut out the middle and put in a new middle section. And that just shipped up, the core section up to Marshall, where it's going under, undergoing static testing. The engine section's already been completed. The testing of that's been completed. And the intertank, the sections between the hydrogen and oxygen tank, has just arrived at Marshall Space Flight Center for testing. The hydrogen and the oxygen tanks will arrive later this year for testing at Marshall too, all for static testing, where they're put under a load to simulate their launch conditions. So this is the largest structural testing campaign since shuttle in the 1970's, and, you know, since this is probably a 50-year rocket, this is really laying the foundation for that kind of generational spacecraft capability that we're building for the Moon and beyond. The upper stage, the exploration upper stage, the NASA one is currently being worked on in design phase, but the ICPS that Paul talked about earlier, the interim cryogenic propulsion stage, is finished and down, already been tested and shipped down to KSC. The engines, the new engine controllers are hot fire tested at Stennis already, and I might even hear a sound of that in a minute. And the boosters, as we talked about, were built in Utah but had full, two full-scale static firing tests at the Orbital ATK facility so far. Core stage and booster avionics testing are undergoing at Marshall right now in specialized, in a specialized, integrated avionics test lab. So the testing is going forward. It's really quite a test campaign. Working on EM1 right at the moment, but, in parallel, getting ready for, I'm sorry, Block 1 to start with, and, in parallel, working on Block 1B for the EM2 mission maybe in 2022. Host: So I'm, I want to understand the full scope. That's, there's a lot of different elements, a lot of different parts of the testing. What are some of the main things that you really want to test? It sounds like structure is one of those things, and how do you do that? How do you test the structure? David Smith: There's a new static test facility at Marshall that's been developed where you essentially set them up vertically, and then you put a load down on the stage, and you do it in many different angles to make sure you can understand not only is it going straight in flight, but if starts experiencing some kind of skew because of the engines, so it undergoes quite a bit of testing that way. That's obviously, the structural modes are the most important. And when we talk about human spaceflight hardware, what that really means for structure is that you test it to a factor of 1.4. So it means there's a 40% margin on the capability of that structure, which is not something that expendable launch vehicles have to worry about. So our rockets are generally a little heavier, a little stiffer, a little more capable, but we do that to provide more margin for the crew in case of emergency. So that's the biggest part of that structural test that's going on right now at Marshall. Host: That goes back to your point, Paul, about one of the main parts of testing this and building SLS is the fact that it is human rated and you have these extra constraints for making sure that safety is and redundancy is one of the primary concerns of building this rocket. Paul Bookout: Exactly, yes. Host: Unbelievable. So the other part is the engines too. You're actually firing the engines. And it's a hot fire test. What's that? David Smith: Well, that's, the shuttle engines are going, they're installed into a test [inaudible] at Stennis. They're put through the same paces as if they were being launched in the vehicle. And remember, some of these engines haven't been test fired in eight years, seven, eight years. Host: Right. David Smith: So it's real important to make sure that they're still, still have the quality that we are looking for at the same time they have a new engine controller. So the controller, the computer that runs these engines have been upgraded from the shuttle days. So it's the first time those two have been mated together. So real important testing. We have I think up to 15 of those engines in inventory, so they're going to be going through those until they, at, probably in the mid-'20's, replacing with a new build of the shuttle engine. So right now, we're still going through the old engines with the new controllers installed. Host: Actually, we do have some audio from that that I really want to play. It's, this is the hot fire test at Stennis, so if you're listening right now, be prepared because it's going to be very loud. [ Engine Sounds ] Host: So that was the hot fire test, and what, you're looking at what components? Are you looking at temperature? Are you looking at propulsion, efficiency? What are the main things that you really want to get out of this test? David Smith: Well, I think the biggest one is, how's the turbo machinery going? You know, if you have turbine blades going at like 3000 rpm and you're spitting out all that fuel at the same time, how is that working out? Is it meeting all the parameters? Is, like you said, that's the temperature? How does it run through its life cycle for that eight-minute burn? That's a long time to run an engine. Host: Yeah. David Smith: So especially, you know, before we launch, you know, the shuttle only had three of these engines firing. Now, we're going to have four of them. So again, that's a unique configuration. So making sure, [inaudible] how these engines will play together will be an important part of the test as well. Host: Did you ever get to see any of these tests in person -- structural tests, hot fire tests, anything like that? David Smith: Yes. Host: Is it really, really loud? David Smith: Well, the Stennis tests, you can get really close to it-- Host: Oh, really? David Smith: Because, you know, it has the flume that comes out the side. And you can get close to a cyclone fence. In fact, you can taste the exhaust because, you know, oxygen and hydrogen comes together and forms water. Host: Right. David Smith: So that, and you have the sprinkler system that's cooling it down. So you get both the sound, right, you get the visual of the flames, and then you get the taste. [laughs] So I don't think you can do that anywhere else. You certainly can't get the taste at Kennedy, so Stennis is really a remarkable opportunity when they do those test fires there. Host: Does it -- I'm imagining like a hot shower or something, just like really-- David Smith: Well, remember, Stennis is pretty humid because it's in Mississippi, so-- Host: Oh, yeah. David Smith: It's going to feel like a hot shower, but, [laughs] yeah. Host: Okay, so I'm, a curious thing -- how does a hot fire test taste? David Smith: Yeah, it has a taste to it. Host: [laughs] So what about the flight hardware for EM1? Where are some of those components? Paul Bookout: Right now, the Orion stage adapter, that's where the 13 CubeSets are going to be housed during launch on EM1. Host: Oh, yeah. Paul Bookout: It's currently at Marshall Space Flight Center. And at the end of, beginning, I'm sorry, of April, it's planned to ship down on the Super Guppy, which is a large carrier aircraft, down to KSC for processing. And once it's down there when we're about six months to launch, that's when the secondary payloads will be integrated into that before stacked on the vehicle. The interim cryogenic propulsion stage, of course, is finished. It was, again, up in Decatur and is already down at KSC doing other final preps on that. The launch vehicle stage adapter, which is being developed at Marshall by Lockheed Martin, they, the primary structure is complete, and they're doing spray foam insulation on the vehicle right now. Again, that's also to help with acoustics aspects of the inside of that, inside of the LVSA. Host: Oh, that's right. Paul Bookout: The core stage, of course, the major components, as David said, the tank, the different tanks will be set up, sent up here for testing. And once they're done testing, they'll be sent back down to Michoud and assembled. And then, the main engines will come over from Stennis and assembled into the full core. That's the liquid oxygen, liquid hydrogen inner tank and the engines. Then, it'll be sent back over to Stennis. As David mentioned earlier, each engine, it would be separately tested, but then all four of these will be tested as, in flight configuration down there at Stennis. So we're running them through the full cycle of, as we're integrating. We're testing as we're putting it together. Host: That's right. Paul Bookout: So we understand that, as we assembled it, is it still operating the way we expected it to? Host: So then, will you, will it be built at Kennedy because that's when it's going to be launched? David Smith: Assembled. Host: I'm sorry, yeah. David Smith: It's built in Michoud, tested at Stennis, and then assembled at Kennedy. Host: Assembled at Kennedy. Paul Bookout: So the solid rocket motors, again, all the segment are, the five segments -- total of ten, five on each side -- have already been cast. They're in final prep for shipping down to KSC on the rail system. And then, just at, similar to shuttle program, once they've reached KSC, they'll be stacked in the VAB one segment at a time, and then the core stage will come in and be connected in the center between them. Then, you have your upper stage or the ICPS, where, I'm sorry, you'll have your LVSA, launch vehicle stage adapter. Then, you'll have your Orion -- let me just start over. Once the core has been installed, then you'll have the launch vehicle stage adapter installed. Then, you'll have your upper stage or the ICPS. And then, on top of that, you'll have the Orion stage adapter where the secondary payloads are. And then, Orion will come in and make, complete the stack. Host: All in this, in the Vertical Assembly Building? Paul Bookout: Yes. Yeah. Remember, it will built to assemble the Saturn V rocket, and-- Host: Yeah. Paul Bookout: We're about that same size, so [laughs] there's plenty of room in there. Host: That's right. It's, going back to that, actually, I don't think we've talked about it on the podcast. The Vertical Assembly Building is, as you can probably tell from the way that this is being assembled, it's gigantic. But it's so big, right, that it has its own weather system that you have to kind of worry about, right? Is that right? David Smith: Yeah, it's-- Paul Bookout: Yes. David Smith: Tall enough where, you know, everything that gets up in there can form its, it could rain a little bit sometimes-- Paul Bookout: Yes. Form clouds up there. David Smith: Yes. Host: Wow. And then, the, you have these giant doors that's going to open, and then you'll just sort of roll the rocket out. David Smith: But one big change is, if you recall, so it's really interesting. You know, a lot of that building was not changed from Saturn V. They only used two of the bays. There's four for shuttle. So they took out the platforms that were for Saturn and put in some shuttle platforms. But for Saturn, excuse me, for Block 1B, they had to do a lot more changes to that. So they had to replace all the platforms for that, and they actually removed a whole bunch of Saturn V, your equipment that had been left, abandoned in place. So it's, that building has really changed from what it was during the shuttle era. Host: So it's really been reconstructed to fit the SLS. That's really the main-- David Smith: Yes. Host: The thing that's going on right now in the VAB. Is it-- David Smith: Right. Host: Is it completed, or is it still going on? David Smith: The platforms are completed. Paul Bookout: Completed. David Smith: For [inaudible] 1, Block 1. Paul Bookout: For Block 1, okay. Host: Right. Paul Bookout: Yeah. And, you know, for SLS, there's still a lot of work at KSC being performed too. It's just not the launch vehicle and all of its hardware for EM1. It's KSC has to go through a redesign on a lot of their components. As David just said, the VAB and all the platforms to be able to reach the hardware where you're stacking SLS. Also, the crawler transporter that takes the mobile launch platform, which has the SLS rocket on -- originally, the Saturn V rocket -- has to be upgraded to fit the SLS rocket. So, in addition, out at the launch pad, they're redoing the flame trenches, re-bricking them because it's going to have a lot more powerful rockets since the S, you know, since the shuttle program. In addition, they're, they have to have a lot bigger water suspension system, you know, because at a lot more power than what shuttle was going through. David Smith: Called rainbirds after the sprinklers. Big rainbirds. Host: Rainbirds. David Smith: Yeah, they kind of go, click, click, click, click, click, on the lawn, but this time, they do it on the engines and stuff. Host: Oh. [laughs] Paul Bookout: So, you know, the water suspension, suppression system is to help with not just the heat but, also, the sound that these rockets, engines, and solid rocket motors, when they ignite, they're very loud. They send out a shock wave. And if you didn't have the water there to suppress or dilute that sound, that would just bounce back off the hard surface up into the vehicle and could damage the vehicle. So it's just not for flame. It's also to protect the vehicle from itself on the acoustics. Host: Okay. That's the, so that's the suppression system? Paul Bookout: Correct. The water that you usually see that starts a couple seconds right before ignition. Host: Actually, I think we do have some audio of that. I don't think this one's quite as loud as a hot fire test, but let's listen to that. This is what the suppression is going to sound like. [ Engine Sounds ] Host: And those are the, that's the clicks, right? That's the, I guess it's basically just like a giant-- David Smith: Sprinkler system. Host: Sprinkler system. Yeah, yeah, yeah. Paul Bookout: Yes. Host: Rocket-size sprinkler system. So you're going to take it from the VAB, and I wanted to get, circle back on that because I think I was calling it Vertical -- is it Vehicle Assembly? David Smith: Vehicle Assembly. Host: Vehicle? So I was getting that wrong. It's Vehicle Assembly Building. You bring it out to a launch pad, and is it going to launch on the same pad that the Saturn V was launching? David Smith: Yes. Host: Okay, so that's 39-- David Smith: In fact, I think -- well, I'm not sure if it's A or B-- Host: A or B. David Smith: But the one that we, that NASA kept, they totally revamped the equipment underneath that concrete mound. Host: Yeah. David Smith: And it's, there's a lot of [inaudible] and electrical equipment that's there in, the remnants from Saturn V, there's still a rubber room. If you know, that's where the, if someone was trapped at the pad, you'd have a safe place in there. So that's still in that same area, which they've now made a historic area, which is kind of interesting. But they, for the first time in 50 years, have to clean out all the old equipment, totally revamp that launch pad for SLS. So it's brand new and ready to go. It's really impressive. Host: So the, what's being suppressed over at this launch pad by that suppression system, is it, is the solid rocket boosters, right, and then are the engines firing at the same time? David Smith: Yes. David Smith: These RS-25-- Paul Bookout: Correct. Host: Engines? Paul Bookout: So-- Host: Everything's all at once? Paul Bookout: Right. Actually, the -- sorry. Actually, the main engines ignite first because we want to make sure all of those are operational and working at peak efficiency because once you start the solid rocket motors, you got to launch because you can't turn off solid rocket motors. So you want to make sure your other four engines are operating nominally, and then you ignite your solid rocket motors. Host: So we've done some testing with the, with these, the main engines, right? The RS-25's? Paul Bookout: Correct. Yes. Also, we have done full-scale testing of the solid rocket motors out there at Orbital ATK in Utah, where they actually constrain him, lay him on the ground sideways, and constrain him, and actually fire, do test fires out there at Utah. Host: Ooh, I've seen that. They actually had a HDR video I think of that -- high dynamic range or something. Paul Bookout: Yes. Host: Yeah, and it was super cool to see. But then, also, just the test itself, actually-- Paul Bookout: Yeah, I've been out there for a couple launches, and it's kind of unique because, with shuttle launch, you listen to the sound, and it's, you know, launching, so it's, after just a few seconds, it, the sound's gone. Where solid rocket motor is, it's operates for two minutes, so you're sitting there feeling that whole sound, you know, [laughs] for two minutes, and it's a really exciting experience to be out there. Host: How did it feel? Did it feel like you were at a loud concert, or even worse than that? Paul Bookout: Well, you're usually about a mile or so away. Host: A mile, okay. Paul Bookout: So, you know, just for safety reasons and everything. Host: That's, yeah. Paul Bookout: So you kind of get to see it off in the distance a little bit, but, yeah, you still feel it and hear it, yeah. And it's kind of unique because you see the smoke, the engines fire off, and the smoke coming out, and then, a couple seconds later, that's when you feel it. So-- Host: How about the RS-25's? Do you feel those too, or not as much? Were out at the RS-25 test? David Smith: Yeah, yeah. Well, the static firing, yeah, you feel it in your, you can get close for that, and you feel it in your stomach. I mean, it's very visceral, the shaking of your, of that sound, so, yeah, you won't forget it once you've had it. Host: That was the sound we played earlier, right? David Smith: Right. Host: Okay. I think the one we still have is the solid rocket booster, I think. Okay, let's play that one. This is the one that Paul was talking, the one out in Utah. >> T minus 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, fire. [ Engine Sounds ] Host: Okay, so that was the test from out in Utah, and if you really, if you turned up the volume on your, on the podcast, you can really feel it. I listened to some of, I would listen to this in the car or hook it up to a nice speaker because you can really feel it there. So those, that's all of those -- the solid rocket boosters, the RS-25, and the suppression systems. So let's go back to the stages and sort of recap the, I guess the stages of all of these engines firing. What's that look like? David Smith: Right. So, you know, the term "stage" means that you have a single entity that provides an impulse for a period of time and then is thrown away. Host: Okay. David Smith: So in the olden days, so that would be Saturn, you know, you'd say Saturn was a three-stage vehicle, right. It had the first stage, the second stage, and then third stage was the injection stage that took, you know, Apollo and the land to the Moon. For both shuttle and for SLS, we really don't, can't call it three stages because these stages work together, which is kind of like they're two-and-a-half stages. So what that means is the core, and, as Paul said, the core starts a little bit earlier, but they're essentially the same time. The core and the booster, the solid rocket motors, boosters, excuse me, turn on at the same time. So they're ignited, and that's the one-and-a-half stage-- Host: Okay. David Smith: Because what happens? After two minutes, the boosters fall off and the core continues, so that's the half stage, in a sense, the boosters. Now, the core continues. And then, finally, the core is expended after eight minutes. It's disposed of in the ocean. And then, you have the upper stage -- in this case, the second of the one-and-a, two-and-a-half stages -- fires to get you to your destination. So you could still call it a three-stage system, but because some of the stages work together they're not really separate stages. So it gets a little confusing. So that's why you really don't hear, that's why people use the term "upper stage" these days and not "third stage" or "second stage" [laughs] because even the expendable vehicles have multiple solids on them, and so they have the same issues. So that's the difference in staging today. And it's more effective to do it this way as well. Host: It's more effective, I guess is it from the perspective of, oh, you can turn this off, you want to make sure everything's working? Is it I guess more reliable? That's why it's more effective? David Smith: Well, it's more effective because you use the power where you need it. At, you know, at sea level, you need the most thrust, so you combine everything together to get you out of the gravity well of Earth. So there's an efficiency with that system that, you know, is improved, is an improvement upon what was done for Saturn and other rockets before then? Host: Okay. So how about the, we're talking about different configurations too -- Block 1, Block 1B -- and how they're going to be different and just sort of evolve. Paul, I think you said you had some secondary payloads I think on 1B. Paul Bookout: Yes, that we're planning for. Host: That we're planning for, okay. Paul Bookout: So, you know, currently, on commercial launch vehicles, CubeSets usually don't have propulsion sets, and they're really going to low Earth orbit or geosynchronous orbit. Host: Yeah. Paul Bookout: And they're pretty much just deployed in those locations, so they don't need a secondary or propulsion system to get to where they need to. On EM1, this is the first opportunity for a secondary payload to be able to have propulsion systems and going to get access to deep space because we're giving them the initial thrust or velocity to get out going to the Moon or into deep space. They only need smaller propulsion system to change their trajectory or where they want to go. So it's, you know, this will be the game changer for secondary payloads. I mean, this is first-time opportunity for these small, little, shoe-size, shoebox-size payloads to be able to get out into deep space. Host: Yeah, and do some great stuff -- orbiting the Moon, land on the Moon. You got some-- Paul Bookout: Right. Host: Great stuff happening in some of these-- Paul Bookout: Right. Host: Secondary payloads. Paul Bookout: As I mentioned in Part 1, EM1's kind of discovering that, well, they really want to be a little bit bigger so they can have a little bit larger propulsion system. So instead of getting off at we call bus stop one right in the middle of the Van Allen belt, they'd like to get off at bus stop two or a little bit past so they don't have to worry about the radiation effects on their systems as much. But they can't do it because they don't have the propulsion system big enough to change their direction that they want to go. So on EM2, because it's a more powerful rocket, there's opportunity for additional mass allocations for secondary payloads. The mass allocation is the mass that's left over that the primary or co-manifested payload doesn't need the full capability of the rocket, so we can use that additional up mass for secondary payloads. So we're offering actually from a 6U- up to a 12U- and even a 27U-size secondary payload. That's huge for secondary payloads wanting to be able to get out into deep space. This allows them to have more power systems, more advanced telemetry, communications, and especially larger propulsion systems so they can get out into different destinations and do all this great science that they want to do in these smaller, less expensive packages. Host: Actually, that blends in nicely to drawing comparisons with SLS to other heavy-lift rockets because SLS is going to be gigantic and take these very, very large payloads. What's the difference between SLS capabilities and some other heavy lift rockets like Delta IV Heavy or Falcon Heavy? Why wouldn't you use just the heavy rockets? Why do you need SLS? Paul Bookout: Existing commercial rockets, they're not destinations going into deep space. They're mainly going into low Earth orbit or geosynchronous orbit. So for a secondary payload to get out into deep space, they'd have to be pretty big, you know, to have a propulsion system larger than a 27U. So the uniqueness of flying on SLS if you want to get out into deep space is that you don't have to have a huge satellite or, and propulsion system. SLS is providing that initial kick or velocity to get you out in the general direction you want to go. And then, you'd have a smaller propulsion system to be able to get out there. So overall, it's a lot less expensive. And again, SLS is giving these small CubeSets the opportunity to get onto deep space. Host: And also, the fact that it's human rated, right. The fact that you can actually put people on it and bring them far into space, right? Paul Bookout: Right. Host: Kind of a big thing. Paul Bookout: Definitely, yes. Host: Is it the only one that's rated for human, for deep space? David Smith: Well, it's the only launch vehicle today that's being designed specifically for that. There's-- Host: I see. David Smith: You could make the argument that a Boeing CST-100 capsule flying on a Falcon, excuse me, on a Atlas is a human-rated system. It's not really. It's an amalgam. And by the way, that's aimed at LEO. So they-- Host: I see. David Smith: You know, it, yes, we are the only ones that are being, designing specifically for that, and it's for safety reasons. Host: So it has to really meet these standards. It has to be redundant. It has to, and the SLS is the big, deep-space rocket that has the standards, has the capabilities, and is going to get you farther. David Smith: Right. Host: Ultimately. Paul Bookout: Exactly. And, you know, to be that safe vehicle for launching humans into space, deep space, you know, we have to have these built-in, redundant systems. We have to do all these testing throughout the whole build of the system. You know, of course, that's a little penalty that we have to have additional mass to be able to have this redundancy, have this extra safety aspects of this vehicle. So that, of course, goes right in against being able to have a larger mass, up mass capability. But we're doing this for human exploration, not robotics exploration, so we're, we have to take those extra steps to make it safe. Host: That's right. So what's the benefit of having this large up mass versus just launching a bunch of rockets with smaller masses? David Smith: Right. We, what's often not fully appreciated is, for human spaceflight, for long duration, you can put together a whole bunch of little modules for humans, but think about it like this: Every time you put together a module, it has to have a hatch. Maybe it has to have two. It has to have a life support system. It has to have a power system, a thermal system. It has to be able to operate autonomously until another small module is joined to it. So you can make a lunar orbiting platform or a Mars deep-space transport out of many small modules brought up over time for that many vehicles, but the problem is it becomes sub optimized. You end up paying maybe 50% more mass for all the structure you don't really have to have. Plus, now, you have many duplicative subsystems for many modules that have to all function flawlessly together and have to wait in space while other modules come up over time and to be joined together. So when you think about this, coming up with this giant, origami-type space station that's deployed over years from many small modules compared to one flight or maybe two flights bringing up a very large module that does everything in one reliable, tested on the ground type of human habitation system, it becomes almost a no-brainer, right. [laughs] If you want to make sure your people are alive over time, you really want that kind of system. Only SLS right now is sized to do that. Other guys can certainly deliver those pieces, but they'd be a lot smaller and you'd have these issues that we just talked about. Host: That's right. And I guess it kind of opens up some opportunities for just, because you can have a larger up mass, because you have more space within the fairing to put things-- David Smith: Right. Host: Now, you have a lot less constraints because even -- I'm going to go back to James Webb, right. James Webb is a wonderful telescope, but it was constrained by what it can-- David Smith: The volume of the fairing. Host: Yeah, so it had to come up with this folding technique to pretty much fit inside the fairing. Otherwise, you couldn't launch the satellite. But I guess you can design, you have a little bit more freedom of design with something a little bit larger, right? David Smith: Or if you wanted to scale up the James Webb design, let's say that was the perfect design for telescopes-- Host: Yeah. David Smith: You could make a telescope that's five times larger with the large fairing that, you know, larger fairings that SLS could fly. So it opens up a whole, either you can have a non-origami type, folding-out type telescope, and it's all great, or, if you want to still do that, it gets you something even larger. So the scale is, the current fairing is, in some cases, the ten-meter fairing would be five times larger than the largest existing fairing today-- Host: Whoa. David Smith: If we could produce that. And that's, you know, we're talking a seven-story building could fit inside that ten, you know, [laughs] that long, the long, ten-meter, diameter, meter, diameter fairing. Host: All right. Just launch my house into space and just-- David Smith: There you go. Host: Kind of get a nice view. David Smith: Well, it'd be your condo building that it would launch-- Host: [laughs] Condo building. David Smith: Not your house. David Smith: Even bigger. Host: Yes. Host: So I kind of wanted to end with just sort of a scope of, we're kind of setting up a scene for what this rocket is capable of. Looking towards the future, and, David, you kind of pointed towards this, was this is a 50-year rocket, right. This is something that we're planning on using for a long time for many missions. How do you see this rocket being used? Like, take us into the future. What is this rocket going to give us? David Smith: So, you know, obviously, the lunar orbiting platform would be the first step. Let's-- Host: Yeah. David Smith: Improve the technologies in our backyard we call the Moon. We use those technologies then to extrapolate a system that can go to Mars safely and start, you know, bringing Mars into this human ring of habitation in our solar system. Some of the more exciting things in tandem are these robotic missions. There's the idea that we can send, because we can go so fast, we, so fast into the deeper reaches of the solar system, that within a five-year mission, we can send out a telescope that could go 200 astronomical units out from the Sun, and actually come back and aim at the Sun, and use the Sun as a gravitational lens to see exoplanets on the other side of the Sun. So we could make the world's largest telescope by having one lens on one side of the Sun and using the Sun's gravity as the other lens, and now seeing planets like we could've never seen them before, all because SLS can send that telescope out in a time frame that we can actually operation a mission, versus, you know, remember, Voyager took 30 years to get outside to, close to the heliosphere. So, you know, it's a, it's such a game changer that the real issue with SLS is we haven't thought about all the stuff we can do with it yet, you know. It kind of bends our imagination in a new way that we haven't been thinking of. Another example is interstellar probe. Again, sending something beyond the heliosphere now. You know, instead of the Voyager drifting out there over 30 to 40 years, we can send something out there in 20 years to break the barrier and see what's on the other side of the heliosphere. And we can do that in an active manner versus we're just getting little pulses from Voyager now still coming back. We can be much more active in that. So a lot of places like JPL are investigating the capability of SLS in ways that we never even thought of recently. So we're just on the very edge of discovering what we can do with the system. Host: Unbelievable. And this just kind of opens up the plan for exploring beyond low Earth orbit, right. You've said the first step for human exploration is going towards the Moon, but now you have a bunch of Moon missions. You kind of develop your skills. You got this Lunar Orbital Platform, the gateway that's going to bring us, the truck stop [laughs] that we call it-- David Smith: Right. Host: Is going to take us further out. And I'm guessing this will be used for the future human missions too beyond this first step. David Smith: Well, if we go to, we talked about I think in the earlier episode, nuclear thermal propulsion. Host: Yeah. David Smith: If we're able to employ that for human transport, we can reduce times to where we can send people maybe even ultimately beyond Mars. So, but only SLS with its capability to loft both mass and volume, when the nuclear, this nuclear thermal propulsion requires large amounts of hydrogen, which requires volume, only the SLS can give us that capability to even see if some of these technologies are usable, versus just relying on the same old technologies as the last 50 years. So we have so much promise in front of us with this. Host: Unbelievable. You guys are getting me all excited for what's to come. I just want to take a time machine, and jump, you know, 20 years into the future, and just see this rocket has done. Paul Bookout: Yep, you're not the only one. David Smith: [laughter] Take us with you. Host: Yeah, that's-- David Smith: We want to be there too. Host: Unbelievable. Hey, David and Paul, thank you so much for coming on, and kind of describing the SLS, and really spending so much time so we can do this in two episodes because there's so much to this story. And honestly, this was the first time that I've actually gone into this much detail for the rocket, so I really appreciate you getting on. And for the listeners, please listen to Parts 1 and 2 and get the whole story of what this rocket is all about. Guys, thanks again for coming on. Houston, we have a podcast.

The Cantor-Bendixson Rank of Certain Bridgeland-Smith Stability Conditions

NASA Astrophysics Data System (ADS)

Aulicino, David

2018-01-01

We provide a novel proof that the set of directions that admit a saddle connection on a meromorphic quadratic differential with at least one pole of order at least two is closed, which generalizes a result of Bridgeland and Smith, and Gaiotto, Moore, and Neitzke. Secondly, we show that this set has finite Cantor-Bendixson rank and give a tight bound. Finally, we present a family of surfaces realizing all possible Cantor-Bendixson ranks. The techniques in the proof of this result exclusively concern Abelian differentials on Riemann surfaces, also known as translation surfaces. The concept of a "slit translation surface" is introduced as the primary tool for studying meromorphic quadratic differentials with higher order poles.

Geology Exchange Program

NASA Astrophysics Data System (ADS)

Because geology professors cannot bring ore deposits from around the globe into their classrooms, the next best thing is to take their students to the deposits, according to David Norman, an associate professor of geochemistry at New Mexico Tech and Angus Moore of the Royal School of Mines. They organized a new exchange program between the New Mexico Institute of Mining and Technology in Socorro, N.M., and the Royal School of Mines in London, England. In May, 14 students from England toured deposits in New Mexico, Arizona, Utah, and Colorado; in the photograph, Norman (on the right) describes a rock from a New Mexico ore deposit to some of the visitors from England. In early June a contingency from New Mexico Tech began studying deposits in England, Spain, and Portugal. Norman and Moore say that the exchange program may be expanded next year.

Five decades ago, Gordon Moore, who would go on to co-found Intel Corporation, made a prescient observation about the exponential advance of semiconductor technology with a corresponding decrease in device cost. His prediction about the pace of doubling of the number of transistors in an integrated circuit came to be known eponymously as Moore’s law and has held true for 50 years. He also foresaw, way back in 1965, the development of home computers, electronic controls in automobiles, portable communications systems, and electronic wrist watches. Moore’s fascinating life, characterized by relentless innovation, charity and breathtaking humility, is the subject ofmore » this comprehensive authorized biography. The enthralling narrative is the product of collaboration between an academic (Thackray), a technology historian (Brock) and a journalist (Jones), and draws its material from numerous interviews, Moore’s meticulously maintained notes and professional records, personal papers, industry data, published volumes, and news accounts.« less

The hyperbolic problem

NASA Astrophysics Data System (ADS)

Gualdesi, Lavinio

2017-04-01

Mooring lines in the Ocean might be seen as a pretty simple seamanlike activity. Connecting valuable scientific instrumentation to it transforms this simple activity into a sophisticated engineering support which needs to be accurately designed, developed, deployed, monitored and hopefully recovered with its precious load of scientific data. This work is an historical travel along the efforts carried out by scientists all over the world to successfully predict mooring line behaviour through both mathematical simulation and experimental verifications. It is at first glance unexpected how many factors one must observe to get closer and closer to a real ocean situation. Most models have dual applications for mooring lines and towed bodies lines equations. Numerous references are provided starting from the oldest one due to Isaac Newton. In his "Philosophiae Naturalis Principia Matematica" (1687) the English scientist, while discussing about the law of motion for bodies in resistant medium, is envisaging a hyperbolic fitting to the phenomenon including asymptotic behaviour in non-resistant media. A non-exhaustive set of mathematical simulations of the mooring lines trajectory prediction is listed hereunder to document how the subject has been under scientific focus over almost a century. Pode (1951) Prior personal computers diffusion a tabular form of calculus of cable geometry was used by generations of engineers keeping in mind the following limitations and approximations: tangential drag coefficients were assumed to be negligible.

Chondrodysplasia punctata (CDP) is etiologically a heterogeneous condition and has been associated with single gene disorders, chromosome abnormalities and teratogenic exposures. The first publication of the association between CDP and maternal autoimmune connective tissue disorder was by Curry et al. 1993]. Chondrodysplasia punctata associated with maternal collagen vascular disease. A new etiology? Presented at the David W. Smith Workshop on Morphogenesis and Malformations, Mont Tremblant, Quebec, August 1993] and subsequently, other cases have been reported. We report on eight cases of maternal collagen vascular disease associated with fetal CDP and included the cases reported by Curry et al. 1993. Chondrodysplasia punctata associated with maternal collagen vascular disease. A new etiology? Presented at the David W. Smith Workshop on Morphogenesis and Malformations, Mont Tremblant, Quebec, August 1993] and Costa et al. [1993]. Maternal systemic lupus erythematosis (SLE) and chondrodysplasia punctata in two infants. Coincidence or association? 1st Meeting of Bone Dysplasia Society, Chicago, June 1993] which were reported in an abstract form. We suggest that maternal autoimmune diseases should be part of the differential diagnosis and investigation in newborns/fetuses with CDP. Thus, in addition to cardiac evaluation, fetuses/newborn to mothers with autoimmune diseases should have fetal ultrasound/newborn examination and if indicated, X-rays, looking for absent/hypoplastic nasal bone, brachydactyly, shortened long bones and epiphyseal stippling.

Assessing the value of silicone and hydrocolloid products in stoma care.

Intact skin among many other functions provides a protective barrier between the body and its environment, which is critical in regulating transepidermal water loss (Wilkinson and Moor, 1982). The frequent application and removal of adhesives can damage skin by stripping away the outer epidermal layers. Older people, very young children and those with an underlying skin disorder may be particularly at risk (Gibelli et al, 1999; Lyons and Smith, 2003). Hydrocolloid adhesives, which hold moisture in the adhesive mass, are more skin friendly than the acrylic adhesives they now replace and have now become the material of choice for ostomy flanges and flange extenders (Smith et al, 2007). To understand stoma care nurses' awareness of the value of technologically advanced silicone and hydrocolloid products, the authors undertook a nationwide postal survey. The survey, commissioned by four companies in the United Kingdom, who make silicone and hydrocolloid products that can be used in stoma care, were keen to evaluate the awareness of these products to confirm their importance to the patient and why they should be appropriately categorized for reimbursement by the Department of Health.

[Book review] The history of ornithology in Virginia

USGS Publications Warehouse

Robbins, C.S.

2005-01-01

Virginia is arguably the birthplace of ornithology in North America. Captain John Smith and naturalist Mark Catesby were among the early describers of Virginia's common birds. David Johnston's book, however, begins by taking the reader back to the Tertiary period, some 65 million years ago, with Storrs Olson's description of fossils from tidewater Virginia. John Guilday, studying bone deposits in mountain caves, identified 80 species of birds, including Rock Ptarmigan and Spruce Grouse, from a time when Virginia's climate differed greatly from that of today. Archaeological studies and accounts of aboriginals in the 17th century complete Chapter 1.

Production Transcript for Ep41 The Space Launch System Part.1.mp3 Gary Jordan (Host): Houston, we have a podcast. Welcome to the official podcast of the NASA Johnson Space Center Episode 41, the Space Launch System part one. I'm Gary Jordan, and I'll be your host today. On this podcast, we bring in the experts, NASA scientists, engineers, astronauts, all to let you know the coolest information right here at NASA. So, today, we're talking about the most powerful rocket since the Saturn V moon rocket. It's called NASA's Space Launch System. So, we've got two guests from Marshall Space Flight Center in Huntsville, Alabama here with us today to tell us a little bit about the rocket, the payloads it will carry. Don't worry. We'll define what a payload is. And then, where it's going to go. Spoiler alert, it will bring people big stuff and little stuff all farther than we've ever gone before. Wait. Why did I do that? That totally ruins the, oh wait. Never mind. It doesn't ruin anything. This is a really good topic, jam packed with information. So much information that we're going to do this in two parts. This is part one. So, with us today are David Smith and Paul Bookout. David is the Vice President for Advanced Programs at Victory Solutions in Huntsville, Alabama. He has a long career in aerospace engineering and is a Subject Matter Expert on rocket architecture and how payloads fit inside the rocket. He wrote the SLS mission planner's guide which gives payload developers a general idea of the capabilities of the rocket and some technical specifications, so they can determine how their payloads might fit inside of it. He looks after some of the big payloads. Our other guest is Dr. Paul Bookout, EM-1 Secondary Payloads Integration Manager who manages integration of five CubeSats in the giant rocket as well as the avionics that will control deployment of the 13 small satellite payloads on the first mission of SLS and Orion called Exploration Mission-1, EM-1. He spends his time managing the little payloads, not much bigger than a shoebox, that goes inside of a skyscraper-sized rocket. So, we're going to be talking about just how powerful this monster rocket is, its unique capabilities, and what it will be used for, where it is in its development, its first mission with the Orion crew vehicle, and then look ahead to the future to missions to the moon, to Mars, and throughout the solar system. So, we are go for launch with Mr. David Smith and Dr. Paul Bookout for the Space Launch System Program. T minus five, four, three, two, one, zero, and liftoff of Episode 41 of Houston, We Have a Podcast. Always wanted to do that. Feel like I just ruined it. You know what? Let's just start. [ Music ] Host: T minus five second and counting. Mark. [ Music ] Host: There she goes. Host: Houston, we have a podcast. [ Music ] Host: All right. Paul and David, thanks so much for coming on the podcast today. We talked about Orion on a few episodes so far but really haven't had the privilege to talk about he giant rocket that Orion is going to be on, the SLS. And, we have you guys here from Marshall to actually talk to us about this rocket. So, thank you very much for coming on. David Smith: Sure. David Smith: Thank you for having us. Host: Our pleasure. Host: All right. Just to sort of back up, we have Paul Bookout and David Smith, so you guys want to talk a little bit about each one, so we can identify your voices. Paul Bookout: David, go ahead. David Smith: Well, sure. I'm just an engineer. My associate Dr. Bookout is a doctor. Host: Okay. David Smith: But, we both work together on trying to find innovative ways to associate payloads with the capability of SLS which is going to be the world's largest rocket. So, I kind of look at the larger payloads, and Dr. Bookout looks at maybe some of the other kind, smaller payloads that can fit in the niches that are left over. Paul Bookout: Well, thank you Vice President David. David Smith: Yes. Paul Bookout: I appreciate you talking about introducing myself. So, what we have is secondary payloads. Again, we're just trying to understand the whole utilization of SLS since it's going to be the most powerful rocket built since the Saturn V. It's going to have a lot more capability, so we want to utilize it to its fullest. Host: Okay. So, you said there's going to be, basically, we're going to utilize the rocket to its maximum potential. We got this big rocket, and we're going to test it. But, while we test it, let's put some cool stuff on it. Paul Bookout: Exactly. Host: So, let's back up and talk about just SLS. What is SLS? What is this giant rocket that we're talking about? Paul Bookout: SLS is America's rocket. It's the next NASA's launch vehicle that's going to be able to put humans back to the moon and further out into deep space. Of course, a lot of it's built on shuttle hardware heritage. The SLS rocket's made up of the solar rocket boosters, a main core, an upper stage, and then the crew Orion spacecraft with a co-manifest payload or a primary payload. And, David will talk a little bit more about that later. So, of course, this is NASA's first exploration class launch vehicle since Saturn V, so we're going to be putting humans back to the moon, out to deep space, and eventually, you know, to Mars systems. It has a very large mass lift capability and also volume, so some of these larger probes that are satellites or probes that are going to outer planets that they'll be able to arrive at their destination in just a few years instead of maybe eight to ten years. [00:05:24] You're cutting that trip down to one or two years. So, it's a lot of savings there. Host: So, that's a really important part to kind of hone in on is just the versatility of this rocket. You're talking about a giant rocket that can take people, giant payloads, faster, farther. That's pretty much the whole summary of the SLS, right? Paul Bookout: Yes. Definitely. Host: So, what's, what does it take to be human rated? So, I guess the difference between something that's not a rocket and something that is. Paul Bookout: Of course, it goes through the whole development process, starts at the beginning. You have to have safety emission assurances involved from the very beginning. Just an overview, you have to have, like redundant systems. If something goes wrong with one system, there's another system to kick in to back up to still make the vehicle safe. There's safety reviews throughout the whole process. We do additional testing, a lot more testing than other commercial launch vehicles do just to make sure that the vehicle is safe for humans. Host: That's really the main thing, right? Paul Bookout: Yeah. [00:06:33] Host: The safety. But, then, also the redundancy because I guess redundancy is cost. Redundancy is weight. So, you have to factor that into a rocket where you can just say, "Oh, if it fails, you know, with the primary systems, it fails." But, at least the only thing we lose is this piece of hardware. And, not to say that that's not a bad thing, but. Paul Bookout: Right. Host: It's very different from human life. So, I guess, absolutely, you need to be considerate of that. Paul Bookout: Right. And, there is a tradeoff, as you was saying. Additional systems, more mass, and that's mass that is being taken away from your primary payloads. Host: Yeah. Paul Bookout: And lift capability, but we need that to be safe. Host: You know what? I actually always wanted to ask this question, but you said primary payloads. I get this question all the time from folks not in NASA, and it's just, we use this term all the time, but what, to you, is a payload? [00:07:22] Paul Bookout: A payload is anything that goes up on top of the rocket that's lifted into space. It can be a satellite. I can be probes. Of course, the Orion spacecraft, once it's on the rocket, it can have its own second co-manifested payload along with it. So, just anything, really, that's launched into space. Host: Does a person count as a payload. Paul Bookout: We don't like to refer to. [ Laughter ] Host: It doesn't humanize it as much, right? Paul Bookout: No, it doesn't. No. Host: So, I guess, for example, going back to that co-manifest thing, the Orion. The Orion would be the payload. That would be the primary thing that you want to bring into orbit. Paul Bookout: Correct. Host: But, then, there's something that is, something called co-manifested which means it's not the primary thing, but it's also part of the part that you want to lift the mission. Paul Bookout: Correct. Host: Okay. Paul Bookout: For example, on the second generation of the SLS rocket, it will have capability of launching a co-manifest payload along with Orion, and it could be anywhere from additional probe going out into the moon, or it can be call separation bus, propulsion system that's launched. And, then, when a habitat is launched, then they can be combined and go to the moon. So, it's, allows us to build capabilities out in space, too, with co-manifested payloads. Host: Okay. Paul Bookout: Along with Orion. Host: Is that one of the things you're working on? Or, you're working on, I guess, secondary payload? Paul Bookout: Yes. I'm mainly focused in on secondary payloads. Host: So, what's secondary payloads? Paul Bookout: Okay. Secondary payloads, or they call auxiliary payloads. Host: Okay. Paul Bookout: They're payloads that do not drive the primary mission of the, of that launch. For example, on EM-1, we have secondary payloads on that. That's EM-1, Exploration Mission-1. Host: Okay. Paul Bookout: First launch of SLS rocket. David Smith: Yeah. Paul Bookout: We have 13 payloads on that, and I'll talk a little bit more about that later. But, the primary requirements they have is for secondary payloads in general is do no harm to the vehicle and minimal impact. So, the do no harm aspect is that we have to fly safe. The whole system, deployment system and everything, is designed to be safe. Like, all the CubeSats are turned off during launch. They have to have, like, redundant systems, as in two separation switches that allow them to turn on. Because, if one fails while we're being launched, it could turn on the systems. So, we have two there. Host: Oh, okay. Paul Bookout: To back that up, to keep it safe. And then, minimal requirements, of course, if the rocket is ready to launch and the secondary payload's not ready yet, it's going to launch. Because it does not affect the primary mission of the payload, of the launch. Host: Right. Paul Bookout: Of that. Host: Well, that puts a lot of constraints on you, then, huh? Paul Bookout: Yes, yes it does. Host: Because, not only do you have to worry about these, and I guess we can kind of hone in on the CubeSats a little bit later. But, you have to worry about the CubeSats, but now you have to add something else to it. Now, you have to add these redundant systems. And then, there's no guarantee that if you're not ready, that's okay. We're going to go without you. Paul Bookout: Right. Exactly. SLS is, the first rocket's not going to be the only configuration of SLS. And, of course, SLS is Space Launch System. We, the first launch is going to be called Block 1. Then, we're going to be stepping up to Block 1B which means we're going to be adding a different upper stage. Right now, we're utilizing an existing Boeing ULA upper stage to use on this mission, mainly to save initial money so we can develop the core stage. And, once the core stage has been developed, then we can have additional funds to start developing the new upper stage or exploration upper stage. Host: Okay. Paul Bookout: Okay? And, that's going to be the Block 1B configuration. And, Block 1B will have actually two configurations. It'll be a crew which was, as we talked about before, the Orion spacecraft with a co-manifested payload. The other configuration will be the Block 1B cargo where that would be your primary payloads. So, the only payload will be that major payload. Host: Okay. So, when you say "Block", you're looking at the entire rocket configuration. Paul Bookout: Correct. Host: And, Block 1 is this configuration with the ULE booster, right? Paul Bookout: Right. Host: Okay. And then, Block 1B has the NASA booster on top. Paul Bookout: Correct. Host: Instead of the ULA, but then you can do crew or cargo on that one. Paul Bookout: Exactly. Host: Whereas, EM-1 you don't, and EM-1, we can get into this later, is, you're not going to have crew on it, right? That's not part of the test. That's for one of the later missions. Paul Bookout: Correct. Host: I see. So, really, the blocks are kind of the stages of developing the rocket into its full capability of. Paul Bookout: Right. Host: Of this eventual Mars lander. That's awesome. So, now, you're using these commercial elements. You're using ULA in Block 1 and the leftover solid rocket boosters until, eventually, 1B, 1B crew, you get to Block 2. Now, you have the configuration. New boosters. You got the NASA upper stage. You got all of these configurations, and now you can go to, where can you go? David Smith: Well. Host: Is it just to Mars? David Smith: Well, you really need Block 2, ultimately, to fulfill a human settlement on the lunar surface as well. Host: Really? David Smith: You need a kind of lift capability. But, if you want to assemble an architecture, because it'll take multiple flights of a Block 2 to assemble a human architecture capable of transiting to Mars, you'll need four to five Block 2 flights at a time to assemble that stack that can go to Mars. Host: So, what's, I guess, how much more power does Block 2 provide you that, I guess, Block 1B would not? David Smith: Well, it nominally, you're talking another 25 tons or so. So, it could bring a second Orion vehicle in comparison because Orion weighs about 25 tons. So, it, really, from a lift standpoint, is maybe a fifth more powerful than the Block 1B, and it gives you that extra diameter, potentially for the payload ferrying that would allow, you know, the smaller the diameter of the ferrying, the taller a lander needs to be. And, think about a lander on the surface of the moon or Mars, if it's three or four stories, that's a lot of vertical height an astronaut has to overcome every time they're taking stuff back and forth. Host: That's right. David Smith: So, we're, the larger the diameter, the shorter can be the squatter, can be the easier it is to manipulate items on and off a lander. Whether it's on the moon or Mars. Host: Okay. Wow. So, then, you're talking about once this Block 2 configuration is done with the new solid rocket boosters, you can actually have a wider payload go on top of the rocket. David Smith: Right. Well, there's a nuclear thermal propulsion that's out there that has the potential of getting people to Mars a lot sooner. It needs a much larger diameter because it used hydrogen as a fuel. Hydrogen is very bulky because it isn't very dense. And so, if we were ever to use a new kind of propulsion that would lower the time to get to Mars, you need a Block 2 vehicle. A smaller rocket will never allow you to do nuclear thermal propulsion. Host: Okay. Let's go back to some of these other configurations. I kind of want to get a sense of the look and feel of this rocket. We sort of talked about it, but to just sort of go into detail. If I was looking at let's just say the Block 1 configuration, the one that's actually going to go for EM-1, what does that look like? How tall is it? What's the weight of it? How much power? David Smith: Right. So, roughly Block 1 and 1B are somewhat similar. Host: Okay. David Smith: They're going to be about the same height as the Saturn V. Host: Oh. David Smith: Which means it's a big rocket, but part of that's because we can't really exceed the vehicle assembly building limitations that are at the Cape. So, you want to make it as big as you can, so you can put as much fuel in it as you can. Basically, the thrust of the Block 1 vehicle which is similar to the Block 1B for the solid rocket motors is about 3.6 million pounds each. Those only fly for about two minutes. Then, you have the core engines. There's four space shuttle era type SSMEs that each have about 512,000 pounds of thrust. You multiply that by four. They operate for about eight minutes. Together, you get about a total thrust of about 8.8 million pounds which gives you an escape velocity of over 22,000 miles an hour. The core stage itself is about 2/3 the length of a football field which is pretty tremendous. One single stage of this vehicle's about 2/3 of a football stadium. And, which is around 212 feet, and the Block 1B ferrying that we talked about, the 8.4-meter diameter ferrying, could accommodate up to three school buses inside its volume. So, that's pretty incredible when you think about the size of what can be lofted in a single vehicle like that. In comparison, the Block 1 vehicle, you know, can throw 70 tons to lower earth orbit where the shuttle can only do 28 tons to low earth orbit. So, it's about three times more powerful than the shuttle. Host: Wow. So, you're talking, you're comparing it to the Saturn V in terms of its size but talking about these efficient engines. What makes, what is it about the engines that's more efficient that's giving you this extra power? David Smith: Well, they, you know, the shuttle engines were rated at 100% thrust originally, and I think they got them up to 109%. So, they actually got them to work 9% more efficiently at the end of the shuttle program. We're taking these up to 11% more thrust, and maybe even 13% more thrust. So, you're really pushing these engines to their limit, and the, it's really coupling their efficiency now at 113% thrust with the reliability of the shuttle system. Host: Unbelievable. The engine itself is called an RS25, right? Paul Bookout: Yes. Host: That's what it's called. And, these are the engines that were on the shuttle. Now, you're pretty much just putting it on the SLS, but it sounds like there's a good reason for that. It's because you've flown the shuttle so many times, improved the capability of it past its, like, total 100% thrust ratio. Now, you're going, you're going past the 100%. So, basically, is like why would we, why would we do something else? We worked so hard on this one. This one is, like, extremely efficient. Why would we, and we can make it even more efficient. That's the logic behind it? Paul Bookout: Well, right. Initially, of course, we have about, I believe, 16 space shuttle main engines or these RS25s left over from the shuttle program. So, we're utilizing the existing hardware to save cost while we're developing the core stage. You know, the first part of the SLS. Host: Yeah. Paul Bookout: And, as you mentioned, we are updating the engines, getting more capability out of them. So, to that point, we can do four per, so we can do about four launches, four rocket, or four engines on each launch. So, we can do about four launches with the current RS25s. Host: Okay. And, that, is that for one of the later configurations? Paul Bookout: That's correct. Host: Okay. Paul Bookout: Yeah. Host: Is it the Block 2? Paul Bookout: The Block 2. Host: Block 2? Paul Bookout: Block 2 and beyond. Host: Oh, okay. I see. I see where the whole idea of staging this whole thing comes from, right? Paul Bookout: Correct. Host: You've got, you're using the leftover solid rocket boosters, and you're using this commercial upper stage. And, it's just basically getting to this point where you're going to maximize the efficiency of the rocket. Paul Bookout: Right. Host: Unbelievable. So, three school buses inside of the 1B configuration, right? That's, is it about the weight of three school buses? Is like taking three school buses to space? David Smith: No, it would be, it would be more than that. Host: More than that? David Smith: I mean, nominally, if you went to the moon, we're going to take, the Block 1B could take roughly 40 tons to lunar vicinity which is, which is pretty incredible. Host: Wow, and just in terms of not only, like, quantity, you're talking three school buses. But, also size. David Smith: Yeah, and mass. Host: Also weight. David Smith: Right. Host: You know, you got all of these, all these different components. So, I guess we can kind of focus in on now that we kind of understand the rocket and the evolution of the rocket, let's go to that first, that first test flight, EM-1. We've talked about EM-1 on the podcast before, especially from testing Orion and that. But, really haven't focused in on what is it about, what is it about EM-1 that we're testing SLS for? So, let's start with that. What are we going to test, and I guess we can kind of start with the overview of EM-1 for those who haven't listened to it before. Paul Bookout: Right. So, EM-1 is, of course, going to be the first launch of the SLS rocket. Its primary segments are, of course, solid rocket motors which are a heritage from shuttle hardware. Shuttle had four segments, where EM-1 is going to have five segment motors. Then, of course, the core stage which is heritage off the shuttle external tank but made longer for additional capability of fuel. And, we're also using the main engines from the shuttle program with updated technology and ratings to get more power out of those four rockets on there. So, that makes up the primary lift capability of the SLS rocket. On top of that, we have an interim cryogenic propulsion stage, which, or second stage, upper stage, that we're utilizing from Boeing, existing hardware for EM-1 mission. And then, of course, in addition to adaptors, then there will be the Orion spacecraft, which is the primary mission of EM-1 is to test out the SLS rocket. Then, also, to test out the Orion spacecraft with its trajectory and telemetries and communications. It's going to be on about a 25 1/2 day mission to distant retrograde orbit. That really means just go way past the moon and come back. Host: Yeah. Paul Bookout: You know, a 25 1/2 day trip. Of course, and, you know, we're doing all this because, again, for the safety aspects. We want to test the vehicle out and Orion spacecraft before we put humans in it. Host: Right. Paul Bookout: So, we want to make sure it's safe, make sure everything works. And, that's that safety aspect, that human rated part of a launch vehicle. Host: So, the human rated part is the Orion can go to 25.5 days, or is this going past what it's expected to possibly operate at? David Smith: I think that's a nominal timeframe for the Orion with crew. So, this is pretty much, I think, its extreme capability. Host: Yeah. David Smith: But, you know, part of it is testing just the systems period. You always, for human rating, you always want to test it far in, you know, far from what the humans will actually experience so that you have a safety factor that's sufficient for human use. Host: Oh, yeah. Because if you're going to be operating on, say, 16 day missions, you don't really want to, okay. Well, let's just test 16. Paul Bookout: Exactly. Host: You really want to go kind of further out and see, all right. Let's see how far this puppy can go. David Smith: And, I think part of this mission's objective is to bring it in at a lunar return velocity to test that heat shield. Host: Yeah. David Smith: You can't do it from low earth orbit. You got to kind of go out and bring it in fast, so. Host: So, what's the difference with EFT-1? That was one of the first test flights we did where we didn't go all the way out to the moon, but we did kind of a, this large apogee so that we can get up to, I think it was some, like 25,000 miles. Or, maybe it was a little slower than that. The difference is between EFT-1 and EM-1. David Smith: I think, I think it was very close to what they would experience in a lunar return, but it's not the actual lunar return. Host: I see. David Smith: Right, so you want to be able to stage it. You want to go out in orbit. You want to test the time that you're out in orbit. That was a very short mission, maybe five or six hours. Now, we're talking 25 days. Well, all the equipment still work when it's, you know, soaked in a cold temperature, hot temperature, all those days. And, now, you're coming in. Will it all work when it comes to the right moment. So, this really puts the pedal to the metal. Host: That's right. So, what is it? I guess the relationship between what are you guys looking at for SLS versus Orion on this particular mission, EM-1? Paul Bookout: So, for SLS, again, we want to test all the systems, make sure they're fully functional. We'll be checking out redundant systems indirectly, of course. And, communications with the vehicle, since it's the first time the vehicle's being launched. We're all, we're talking with the vehicle all the way up. Host: Yeah. Paul Bookout: So, we want to make sure all those ground systems are ready to support, actually, human flight mission. So, it's just not the vehicle. It's the overall architecture of everything that goes into supporting a launch that we want to verify and check out. Host: Oh, that's right. Now, we're preparing to go into fly deep space missions. So, not only is it, all right, let's test the hardware, but let's test to operational aspect. Paul Bookout: Exactly. Host: Let's test what it's going to take to actually do these missions from the broadest perspective possible. David Smith: And, that includes, even, just bringing the, you know, the pieces are being built all over the place. Host: Yeah. David Smith: And, tested all over the place. So, just bringing them together at the cape and making sure they can be integrated in a safe and timely fashion for launch. That, in itself, is a really important objective. We're talking about such a large rocket. Paul Bookout: Yeah, so this is the first time all those components going to be coming together, and there's going to be hiccups along the way. And, we just need to understand how this vehicle goes together and make sure we do it correctly. Host: So, you say the vehicle's going to be talking to you guys throughout its flight. What is it going to be telling you? What kinds of data are you really looking for that's really going to tell you that this thing is working how we're expecting it to work? David Smith: Well, remember, you're talking to payload guys, so, you know, we're more interested in seeing what the payload's going to experience. Host: Yeah. David Smith: But, think about this. When it launches on the pad, it has an incredible noise issue coming off that mobile launch platform. That's why, if you remember, they had these things called rainbirds, the big sprinklers that start spraying as soon as the engines go to try to mitigate that noise. Host: Right. David Smith: The payload is particularly sensitive to it. Obviously, the vehicle itself is sensitive to that noise as well. So, acoustic mitigation is one of the most important things at launch. Then, we have a thermal issue, right? We go up to max Q, max dynamic pressure. We have a certain heating that is, occurs on the outside of the vehicle. And, before, we got to get through all that heating before we can make sure that the crew is going to be safe, that we can take the shielding off the Orion and so forth. So, we're going to be testing all those environmental concerns as we go forward, and of course, the jettisoning of, you know, the SRBs off the core stage. Then, the ICPS in Orion off the core stage. And then, of course, then, the Orion off the ICPS. All these jettison events, and there's quite a few of them, are extremely important, and we need to test those. Each one has its associated thermal and acoustic issues. So, we're going to test each one of those as it goes forward. Paul Bookout: Since this is the first launch of SLS rocket, we don't really understand the full environments that it's going to be launched in. As David mentioned, the thermal, interior thermal, acoustic, vibration. It's the first time we're going to launch it. So, what we're also have is a lot of instrumentation on this vehicle to be able to measure the actual vibration levels and everything else. So, we can, once we go back to designing and looking at what we call safety factors, reducing those so we can have more margin on the vehicle and means that goes into more mass lift capabilities. So, we're trying to understand the overall characteristics of the vehicle itself. So, in addition, for secondary payload, or payloads in general, we can give them more of an accurate environment that they will see during launch. As in, how much vibration they'll feel, how much thermal environments that they'll see. So, when they start designing their payloads for, to run the ride on this vehicle, they can have more of an accurate environment. And, maybe not have, make it a lot more efficient design. Host: Okay. So, then, what data are you going off of now based on, you guess you haven't launched the SLS. So, what are you assuming, or where are you getting the data from? David Smith: We have, we started off with assuming, at least for the payloads, that we would provide an ELV, and expendable launch vehicle class environment. Host: Okay. David Smith: So, if you've flown on Atlas or Delta, you should expect nothing worse than that. Host: Okay. David Smith: That's our starting point. Host: Oh, okay. David Smith: Now, what Paul's going into is we're going to try to characterize is that really true? So, the first flight's important. Are we in? Are we out? What do we have to do? Is there more foam that you got to put in the payload section to mitigate the noise? That's what we're trying to figure out. But, we should be within an ELV class is what we're projecting right now. Host: Okay. So, then, I'm assuming you're going to have some actual science on board EM-1, right? Because you're testing, you're testing the structure of EM-1. You're testing the rocket. But then, you have this mission. Why not take advantage of it? Is there anything else going on the EM-1? Paul Bookout: Oh, definitely. Host: Okay, good. Paul Bookout: Yes. We have, we'll have 13 secondary payloads that we're going to be launching on EM-1. Host: Wow. Paul Bookout: That'll, that is located in the Orion stage adapter. That's the segment that connects the SLS rocket to the Orion spacecraft. So, it's a small ring about five feet high. About 18 or so feet in diameter. And, along the inner circumference of that is where we are mounting these 13 secondary payloads. Host: Oh, so I guess they have to be kind of small, right? That's not a lot of space compared to the, what's in the ferrying. Paul Bookout: Correct. So, on EM-1, we have 13 CubeSats. CubeSats are defined as a, we call a 1U, which is about ten by ten by ten-centimeter cube. Host: Okay. Paul Bookout: So, what we're having on EM-1 is allowing them to go up to what we call a 6U. So, it's a CubeSat that's about the, a little bit larger than the size of a shoebox, a large shoebox. Host: Okay. Paul Bookout: And, that's kind of the dimensions of these 6U CubeSats that we're having on EM-1. David Smith: Which is the most common CubeSat, really, today, right? Paul Bookout: Correct. Exactly. So, we have multiple missions that these payloads are going to be doing. So, we've got one destination is to the moon. We have Lunar Flashlight which is out of Jet Propulsion Laboratory, and their primary mission is to search for ice deposits and resources on the moon using a laser. Host: Ooh. Paul Bookout: Okay. And, the second one is Lunar IceCube which is Morehead State University up in Kentucky. And, they're going to also be searching for water of all forms and volatiles on the moon using infrared spectrometer. These are some big words that I can't even define, so. [ Laughter ] LunaH-Map is from Arizona State University, and they're going to be creating high fidelity map of near surface hydrogen in craters on the moon. Lunar IR is from Lockheed Martin in Colorado, and they're going to be performing advanced infrared imagery of lunar surface. We've got one that's going to the sun facility, and it's called CuSP. It's from Southwest Research Institute here in Texas, and it's going to be measuring particles and magnetic fields of space weather between us and the sun. We have one that's going around the Earth. It's called EQUULEUS. It's a Japanese payload, and we actually have three international payloads on this mission. And, I'll touch on those others. Host: Awesome. Paul Bookout: So, again, EQUULEUS is from JAXA. It's the University of Tokyo supporting that. I mean, it's imaging the Earth's plasma sphere for a better understanding of Earth radiation environment. And also, it's going to be initially on the far side of the moon and detecting any meteor crater flashes that may impact the far side of the moon. Host: Wow. Paul Bookout: So, they'll be out there for about two months or so and just hopefully they'll be able to catch something. Some of the other missions are BioSentinel. It's from Ames Research Center, and they're going to be using baker's yeast to see the effects of radiation on actual live items, you know, live yeast. And, then, ArgoMoon, which is the European Space Agency, is built in Italy. It's going to be observing the interim cryogenic propulsion stage. That's upper stage is going to be deployed. Look at that upper stage, and then it's going to go on some additional missions. And, it's going to look at the upper stage to see what kind of effects the environment has during liftoff on the upper stage. Because, until now, we, once the upper stage is launched, we usually don't get a chance to look the conditions of that. This will give us some feedback and see what the upper stage has went through, if there's any damage or anything. Host: It sounds like these CubeSats are all over the place. Paul Bookout: Yes. Yeah. I've got a couple more here. Host: Oh, really. Paul Bookout: I haven't got to my two favorite yet. So. Host: Oh, we're standing by. Paul Bookout: Okay. Centennial Challenge. That was a challenge that NASA set up called Cube Quest, and it's to help develop communications for these smaller CubeSats. There's two challenges. One was a lunar challenge to around the lunar surface and for longevity. And, the other one was a deep space mission which was a CubeSat, as it says, going out into deep space to see how far and long and what burst rates and clarity that you can have in your signals. So, there's total prizes for everything through all the development and final missions. It's up to $5 million. Host: Wow. Paul Bookout: So, that's a lot of money. Host: Yeah. Paul Bookout: Spread out over those. So, you did, you asked what my two favorite payloads are. Host: Oh, yeah. Paul Bookout: Let me tell you. One of them is NEA Scout. That's developed at Marshall Spaceflight Center. What's unique about that is NEA Scout means Near Earth Asteroid. So, they're going to be going to a near earth asteroid. But, the exciting thing about it is that they're going to be using solar cell to get there for their propulsion system. So, this is the first time a solar cell will be used to, for propulsion out into deep space. There have been other missions in low earth orbit to check out the technology and feasibility of solar cells, but this is the first time going out to deep space. And, for a CubeSat that's a little bit larger than a shoebox, it will be deploying the cell that will be 40 by 40 feet. Host: Whoa. Paul Bookout: So, that's huge. Host: Wait, and a little CubeSat. Paul Bookout: In a little CubeSat. Host: And, it deploys a 40 foot. Paul Bookout: Yes. Host: Oh, wow. Paul Bookout: Yeah, so that solar cell is very thin material. Host: Yeah. It must be to fold up into, like, this ten-centimeter cube thing. Paul Bookout: Exactly. Host: So, so, the solar. Paul Bookout: You said ten centimeters. 6U CubeSat is 10 by 20 by 30. Host: Oh, because this is 6U. Paul Bookout: 6U, correct. Host: Oh, okay. Okay. Okay. So, solar sails, though, this is, it basically unfurls this 40-foot sail, and is it the one where the high-power laser that pushes it? Paul Bookout: No. Paul Bookout: That's different. Paul Bookout: This is going to ride the solar winds. Paul Bookout: Ride the solar winds. Paul Bookout: Solar particles will be pushing it along. It'll do actually a fly by the near-earth asteroid as it comes up. It'll be taking images all the way around as it passes. Host: Okay. Wow. Paul Bookout: So, and my ultimate favorite one is. Host: Yeah, we didn't get the last one. Paul Bookout: Is actually the one that I'm the Secondary Payload Integration Manager for. Host: Oh. Paul Bookout: So, it's one of my CubeSats. Host: So, it's an unbiased favorite, then. Paul Bookout: Yes. Host: Okay. Paul Bookout: Yeah, still. It's called OMOTENASHI. It's another Japanese CubeSat. Host: Okay. Paul Bookout: And, their mission is to land on the moon. Host: Oh. Paul Bookout: Can you imagine a small little CubeSat, you know, a little bit larger than a shoebox, land on the moon? Of course, and the big thing about it is that they're going to be using a solid rocket motor to slow down to be able to land on the moon. So, that's one of the things on EM-1 that we're offering that previous commercial launch vehicles and that don't offer propulsion systems for secondary payload to be able to utilize that. That's one thing EM-1 and SLS is allowing. So, that's a huge deal. Host: Yeah. Paul Bookout: For those. So, if OMOTENASHI is successful at landing on the moon, they'll be the fourth nation in the world to have actually land and do some science on the moon. Host: Wow. Paul Bookout: You know. Host: So, what kind of science? Paul Bookout: Well, because, again, they're still a small payload, so they can't get large science instruments to the moon, when they land, actually land on the moon, all that will be left is about the size of a sandwich box. Because they have to get rid of all the extra weight to be able to slow down enough to be able to land. And, they'll probably so some soil impact measurements, as in how soft vibration, shock, as it's landing on the moon. And, I, so, and they're only going to be able to do it for about 30 minutes or so. Again, because of the size, what we're limiting them to. Host: Yeah. Paul Bookout: They can't get the mechanics, orbital mechanics and velocities and everything. I'm sorry. Host: So, it's, it's kind of general on where you can land, then? It's just like, it's just going to land. It's not going to land in a targeted spot, I guess? Paul Bookout: Correct. They know the general vicinity where it's going to land. Host: Okay. Paul Bookout: But, they can't have ultimate control, like any of the other landers that have larger systems, propulsion systems, to slow them down. So, they would be actually, once the solar motor fires, they'll still be traveling at about 60 miles an hour when they impact the moon. So, they're going to inflate these impact balloons to actually bounce, similar to what they've done on Mars, some of the Mars Rovers. Host: Okay. Paul Bookout: So, it'll come and impact moon and bounce and then finally rest on the moon. Host: Okay. Paul Bookout: And, do about 30 minutes of impact soil measurements. Host: Wow. How would that be, though? I'm imagining, I mean, landing at 60 miles an hour. That's, you know. Paul Bookout: Well. Host: That's not slow, but at the same time, it's the moon, right? It's. Paul Bookout: Right. Yes, but then again, you're not going directly into it. You know, you're coming in at an angle, too. Host: At an angle. Paul Bookout: So, it's not a fully impact. Host: Okay. Great. Paul Bookout: Direct impact, so. Host: So, you got all these CubeSats going around the Earth, around the upper stage, around the moon, on the moon, to deep space. Where do you deploy, how does that work? Where do you deploy everything? It's not just like you just let everything go at all. It has to be pretty controlled because each one has a very specific mission. Paul Bookout: Right. We've created what we call bus stops. Host: Oh. Paul Bookout: They're basically different aspects of the trajectory of the upper stage. So, the first bus stop is when you're in between the two radiation belts or Van Allen belts. Bus stop two is when you've passed all the radiation belts. Bus stop three is half way between the Earth and the moon. Bus stop four is the closest proximity to the moon, and bus stop five is when you're going into a heliosynchronous or sun orbit. And, that's where the upper stage will be disposed into the sun orbit. So, when a payload says, "Hey, I want to get off at 200,000 miles away from the Earth." Well, okay, where is that exactly? So, that's why we kind of created these bus stops. Host: I see. Paul Bookout: They can get off anywhere they want to, but it helps us relate to the areas where they want off. So, most of them are wanting off at stop one. About seven or eight of them. Because they need to get out and start changing their trajectory as soon as possible. Again, we're offering propulsion systems, but they're not large enough to have really change their directions further on. So, a little change at first makes a big change later. Host: Yeah. Paul Bookout: So, they want to get off to be able to do that, make those little changes. Most of the payloads that are going to lunar orbit, what they're wanting to do is slow down because the ICPS, you know, is launching Orion into this distant retrograde orbit. And, you know, way past the moon. Host: Yeah. Paul Bookout: So, it has a lot of velocity heading that way, and if the payloads don't slow down, they'll just go flying past the moon. The moon can't, doesn't have enough gravity to pull them back into an orbit. And, some of them, even though they are going to the moon, they'll actually fly past the moon, and it may take a month or so for them to come back, to slow down enough to come back and get hooked into the moon's gravity and start orbiting the moon. Host: Oh, wow. Paul Bookout: So, it's not a direct flight into the moon orbit, just because they don't have the propulsion systems large enough to be able to do that. Host: So, is it fair to say they're all going to be in a very similar orbit, or are they all going to kind of go their respective directions? Paul Bookout: They're going to do their respective ways. Host: Okay. Paul Bookout: Some of them wants to do in the crater, so they're going to be going to the pole system, up to the poles to look see if there's ice up in there. And, some of them will just be doing a regular geosynchronous type of orbit. Host: Okay. Paul Bookout: Type thing. Host: All right. Paul Bookout: We talked about where these, what the payloads are and where they're going to want to get off. To be able to allow them to get off, again, we have to have a deployment system where, again, some of the primary requirements for EM-1 was or SLS is to do no harm and to have minimal impact to the vehicle. Host: Yes. Paul Bookout: Well, to do that latter one, what we've come up with a system is that we will receive an energy, the avionics unit for deploying the secondary payloads will receive an energy pulse for, from Orion. Or, I'm sorry. Will receive an energy pulse from the upper stage once Orion has already left and the upper stage has gone through its disposal maneuvers. That means burning off extra fuel and everything making it safe. Right before it shuts down, it will turn on the avionics unit for deploying the secondary payloads. Then, the upper stage turns off. So, we wake up, and we've got our own internal battery system. And, each payload is inside of a dispenser, and so, the dispenser operates as the, has a spring-loaded lid. And, the payloads inside are installed by compressing the spring. So, when the, when it's time for that particular payload to be deployed, we get an energy pulse from the avionics unit sent to the dispenser to open the door. The door flings open, and then the secondary payload is pushed out by springs. So, that's how they're deployed. Host: Okay. So, like a, so, like an SLS jack in the box. [laughter] Paul Bookout: If you will. Host: That's what I'm imagining. Obviously, it's going to shoot out. Paul Bookout: We have pulled those analogies before, but I'll let you state it. Host: And then, I guess there's, you get this power pulse that's going to, I guess, be directed to whatever seven is going to be part of bus stop one, and whatever the next ones for bus stop two. Paul Bookout: Correct. Host: Okay. Paul Bookout: And, they'll be deployed, if there's multiple at a particular bus stop, they'll be deployed a minute or two away from each other, after each other because we don't want to be able to deploy one and then deploy another one right behind it. Host: Yeah. Paul Bookout: And then, they have recontact. Host: So, I'm trying to imagine the way everything is situated in my head, and at this part of the flight when you're starting to deploy these secondary payloads, what does, what does the rocket, I guess, or what does the piece that's actually flying, what does it look like? I guess you have Orion and then there's this deployment system, and then there's, is it the upper stage behind it? Paul Bookout: Okay. So, once we've launched. Host: Yeah. Paul Bookout: After about two minutes, the solar rocket motors are. David Smith: Jettisoned. Paul Bookout: Jettisoned. And then, the core stage lifts the rest of the vehicle up into orbit. And, after that time, when the core stage is spent, then it'll be jettisoned. And then, you'll have your upper stage and your Orion spacecraft which of course the secondary payloads are still in part of that. And then, then, it'll go into what they call a translunar injection that's basically the upper stage will ignite and put Orion into its mission profile going past the moon. Host: So, at this point, right before it ignites, it's still in, I guess, Earth orbit, and the translunar injection gets it to the moon. Paul Bookout: Correct. Host: Okay. Paul Bookout: Okay. So, once the upper stage has spent its fuel, the Orion spacecraft will separate, okay? From the upper stage. So, it'll go through on to its mission. And then, about 30 minutes later, 20, 30 minutes later, the secondary payloads will start their deployment. Host: I see. Okay. Paul Bookout: So, Orion is well away and actually speeding faster away from the upper stage. Host: Yeah. Paul Bookout: The upper stage, once it goes through its disposal maneuver, is actually flying kind of, you would say, backwards, engine first, towards the moon. Host: Oh. Paul Bookout: So, the secondary payloads will be ejected out the other direction. So. Host: Okay. So, so. Paul Bookout: So, when they're deployed, the ICPS won't run back into them. Host: That's right. Paul Bookout: Okay. So, they'll be deployed in the other direction. Host: But, now, Orion is going in, it's doing its own thing. Paul Bookout: Correct. Host: Because it did its job. It delivered Orion. That's the primary payload. Now, it's off. But, the secondary payloads are still part of this upper stage. They haven't gone with Orion. They're totally separate. Paul Bookout: Correct. They have their own. Host: So, it's like, they're kind of doing, they're going. Paul Bookout: Yeah. Host: Different ways. Interesting. Paul Bookout: Yeah, they have their own mission profiles going in all different directions. Host: Okay. Okay. I don't know why that wasn't clear to me before but thank you. All right. So, I guess kind of backing up from there, you're talking about the solid rocket boosters are disposed. The core stage is disposed. Where are all these pieces going? Paul Bookout: Okay. Depending on their mission profile, all the secondary payloads are going to end of missions at different places. Some of them will be actually crashing into the moon, and that's common where the other countries and their lunar missions depositing on the moon. Some will, one or two will burn up in Earth's atmosphere as it comes back. Some of the other ones that are going out into deep space, of course, just keep going. The CuSP, which is going to solar. I'm sorry. CuSP, which is going to the sun's vicinity will just stay out there and eventually be pulled into the sun. Host: Okay. Host: So, that's all the secondary payloads. Paul Bookout: Correct. And, for each mission, each payload that's launched on U.S. rockets, they all have to have an end of mission plan. What are they going to do to end their mission, not just to be left out there as space junk. Because that's, we're having, sorry. We're starting to have a lot of problems with, as you know, there's a lot of space junk around Earth. Host: Oh, yeah. Paul Bookout: And, you don't want that same situation around other planets, too. Host: That's fair. That's fair. And, that's why, that's part of the, I mean, this is going back, but Cassini, right? That was the whole. It did its thing, and instead of just letting it be. It had a controlled entry into Saturn so that it didn't contaminate any other. Paul Bookout: Exactly. Yes. Host: Any other bodies. Yes, yes, of course. Paul Bookout: And, it doesn't matter what size you are. Host: Yeah. Paul Bookout: Even these small CubeSats have to have an end of mission. Host: Have to have an end of mission. Paul Bookout: Yes. Host: Awesome. But, I did want to go back to some of the earlier parts of the mission, right after launch. You know, you're talking about solid rocket boosters separating being. David Smith: Those go into the ocean. Host: Ocean? Okay. David Smith: Still, but they're not recovered this time. Host: Oh, okay. David Smith: You know, for shuttle, they were recovered. This time, it's too difficult. They're too large. So, they're just going to sink. Host: Okay. [00:48:19] David Smith: The external tank is, it can't go into orbit, so it's kind of lofted in such a way that it'll break up over the Indian Ocean safely. Host: Ah. David Smith: So, it's a very large tank. You know, this is much larger than the external tank of shuttle, so it's very important that it break up safely. So, that's, that's why you need the upper stage to actually bring the payload up into a circular orbit around the Earth. Otherwise, the payload would go down with the core module as well. Host: Okay. Okay. And, what about the, I guess, the upper stage. You said it's going to be doing this deployment, but then, after it deploys [inaudible]. David Smith: It's heliocentric. It goes into a sun, heliocentric disposal. Host: Sun heliocentric disposal. David Smith: So, it kind of goes away, and we should, hopefully, not see it again. Host: Okay. All right. That's a very nice summary of EM-1, and I feel like there's so much more to talk about. I kind of wanted to get into, you know, where are we now with SLS, all the history of it. So, I think we should take a break and just sort of let this one be Episode 41. We'll come back, and we'll do Episode 42 and just sort of get into the process behind building the SLS and then the journeys of where it's going to go and beyond. So, guys, thank you so much for coming on. We'll take a break. I'll see you in a few minutes. And, for everyone else, I guess we'll see you for the next episode. David Smith: All right. David Smith: Great, thank you. Look forward to it. Paul Bookout: Thank you. [ Music ] Houston, go ahead. [ Inaudible Comment ] [inaudible] for all mankind. Not because they are easy, but because they are hard. Welcome to space [echo]. Host: Hey, thanks for sticking around. So, the best places to follow development and delivery of the rocket as we test the major components and deliver it piece by piece to the Kennedy Space Center are on the social media channels on the web for the Space Launch System. So, first the website. You can go to www.nasa.gov/ guess what? SLS. That's where you can get the latest, the greatest on the Space Launch System. On Twitter, it's @nasa underscore SLS. On Facebook, it's NASASLS, that's one word. Or, this is one of the things that actually David Smith wrote. You can actually search SLS Mission Planner's Guide. And, it's a document that you can find on the web. You can download it, and it actually has a lot of great information on just the whole scope of the Space Launch System. We're really looking forward to the first launch of SLS and Orion from the Kennedy in a couple years. Sounds like we're well on our way to the pad, and we'll be launching astronauts back to the moon in just a few short years. If you have questions on SLS and its development, use the hashtag asknasa on your favorite platform. Just go to the Johnson accounts. Those are the ones we look at. The NASA Johnson Space Center accounts on Facebook, Twitter, and Instagram. You can send an idea or a question, and we'll make sure to mention it's for, or just make sure to mention it's for Houston, We Have a Podcast, and we'll bring it up in a later episode. Or, maybe address it in an entire episode. The whole episode will be dedicated to the question. Who knows? So, this podcast was recorded on March 20, 2018. Thanks to Alex Perryman, Rachel Craft, Laura Reshawn [assumed spelling], Kelly Humphries, Pat Ryan, Tyler Martin, Bev Perry, and all the folks at the Marshall Spaceflight Center for coming on to help to put this together. Thanks again to Dr. Paul Bookout and Mr. David Smith for coming on the show. We'll be back next week with part two.

This is a very well-written and beautifully presented book. It is north American in origin and, while it will be invaluable for teachers of statistics to nurses and other healthcare professionals, it is probably not suitable for many preor post-registration students in health in the UK. The material is quite advanced and, while well illustrated, exemplified and with numerous examples for students, it takes a fairly mathematical approach in places. Nevertheless, the book has much to commend it, including a CD-ROM package containing tutorials, a statistical package, solutions based on the exercises in the text and case studies.

In R. Jeffrey Smith's News and Comment article "Antisatellite weapon sets dangerous course" (14 Oct., p. 140), a remark on page 141 (column 3) by Richard Garwin about the usefulness of rockets, balloons, and aircraft to supplant U.S. photoreconnaissance and meterological satellites was inadvertently attributed to Robert Buchheim. And a characterization on page 141 (column 2) of the Soviet antisatellite weapon, or ASAT, was actually made by General Lewis Allen, the former Air Force chief of staff, not by General David Jones, the former chairman of the Joint Chiefs of Staff. Finally, a footnote on page 142 should have identified the Patriot as an air-to-air missile, not an air-to-ground missile.

Evolution and the neurosciences down-under.

PubMed

Macmillan, Malcolm

2009-01-01

At the end of the nineteenth and the beginning of the twentieth century three Australians made notable contributions to founding the neurosciences: Alfred Walter Campbell (1868-1937) conducted the first extensive histological studies of the human brain; Grafton Elliot Smith (1871-1937) studied the monotreme brain and established the basis for understanding the mammalian brain; and Stanley David Porteus (1883-1972) extended his studies of intellectual disability to encompass the relation between brain size and intelligence. The work of each was decisively influenced by important members of the Edinburgh medical school or by Edinburgh medical graduates: William Turner (1832-1916) and William Rutherford (1839-1899) Professors of Anatomy and Physiology respectively at Edinburgh; James Thomas Wilson (1861-1945) Professor of Anatomy at the University of Sydney; and Richard James Arthur Berry (1867-1962) Professor of Anatomy at the University of Melbourne. An important aspect of the influence on the Australians was a materialist view of brain function but the work of all was most important for a theory even more central held by the Scots who had influenced them: Darwin's theory of evolution. The importance of the work of Campbell and especially that of Smith for Darwinism is contrasted with Darwin's own indifference to the peculiarities of the Australian fauna he observed when he visited Australia during HMS Beagle's voyage of discovery in 1836.

Special Relativity in Week One: 3) Introducing the Lorentz Contraction

NASA Astrophysics Data System (ADS)

Huggins, Elisha

2011-05-01

This is the third of four articles on teaching special relativity in the first week of an introductory physics course.1,2 With Einstein's second postulate that the speed of light is the same to all observers, we could use the light pulse clock to introduce time dilation. But we had difficulty introducing the Lorentz contraction until we saw the movie "Time Dilation, an Experiment with Mu-Mesons" by David Frisch and James Smith.3,4 The movie demonstrates that time dilation and the Lorentz contraction are essentially two sides of the same coin. Here we take the muon's point of view for a more intuitive understanding of the Lorentz contraction, and use the results of the movie to provide an insight into the way we interpret experimental results involving special relativity.

A comparison of the impact of 'seagrass-friendly' boat mooring systems on Posidonia australis.

PubMed

Demers, Marie-Claire A; Davis, Andrew R; Knott, Nathan A

2013-02-01

Permanent boat moorings have contributed to the decline of seagrasses worldwide, prompting the development of 'seagrass-friendly' moorings. We contrasted seagrass cover and density (predominantly Posidonia australis) in the vicinity of three mooring types and nearby reference areas lacking moorings in Jervis Bay, Australia. We examined two types of 'seagrass-friendly' mooring and a conventional 'swing' mooring. 'Swing' moorings produced significant seagrass scour, denuding patches of ~9 m radius. Seagrass-friendly 'cyclone' moorings produced extensive denuded patches (average radius of ~18 m). Seagrass-friendly 'screw' moorings, conversely, had similar seagrass cover to nearby reference areas. Our findings reinforce previous work highlighting the negative effects of 'swing' and 'cyclone' moorings. In contrast, the previously unstudied 'screw' moorings were highly effective. We conclude that regular maintenance of moorings and the monitoring of surrounding seagrass are required to ensure that 'seagrass-friendly' moorings are operating effectively. This is important, as following damage Posidonia will take many decades to recover. Copyright © 2012 Elsevier Ltd. All rights reserved.

In the background is David J. Smith, Ph.D., NASA E-MIST principal investigator. The container was designed and built at Kennedy. The 80-pound structure features four doors that rotate to expose up to 10 microbial samples each for a predetermined period of time in the Earth's stratosphere. The E-MIST experiment will launch on the exterior of a giant scientific balloon gondola at about 8 a.m. MST on Aug. 24 from Ft. Sumner, New Mexico. It will soar 125,000 feet above the Earth during a 5-hour journey over the desert to understand how spore-forming bacteria, commonly found in spacecraft assembly facilities can survive.

The structure of the microbial communities in low-moor and high-moor peat bogs of Tomsk oblast

NASA Astrophysics Data System (ADS)

Dobrovol'skaya, T. G.; Golovchenko, A. V.; Kukharenko, O. S.; Yakushev, A. V.; Semenova, T. A.; Inisheva, L. A.

2012-03-01

The number, structure, and physical state of the microbial communities in high-moor and low-moor peat bogs were compared. Distinct differences in these characteristics were revealed. The microbial biomass in the high-moor peat exceeded that in the low-moor peat by 2-9 times. Fungi predominated in the high-moor peat, whereas bacteria were the dominant microorganisms in the low-moor peat. The micromycetal complexes of the high-moor peat were characterized by a high portion of dark-colored representatives; the complexes of the low-moor peat were dominated by fast-growing fungi. The species of the Penicillum genus were dominant in the high-moor peat; the species of Trichoderma were abundant in the low-moor peat. In the former, the bacteria were distinguished as minor components; in the latter, they predominated in the saprotrophic bacterial complex. In the high-moor peat, the microorganisms were represented by bacilli, while, in the low-moor peat, by cytophages, myxobacteria, and actinobacteria. The different physiological states of the bacteria in the studied objects reflecting the duration of the lag phase and the readiness of the metabolic system to consume different substrates were demonstrated for the first time. The relationships between the trophic characteristics of bacterial habitats and the capacity of the bacteria to consume substrates were established.

An account is given of the life, scientific contributions, and passing of Laurance David Hall (1938-2009), including his early history and education at the University of Bristol, UK, and the synthesis and NMR spectroscopy of carbohydrates and other natural products during ∼20 years of research and teaching at the University of British Columbia in Vancouver, Canada. Lists of graduate students, post-doctoral fellows, and sabbatical visitors are provided for this period. Following a generous endowment by Dr. Herchel Smith, Professor Hall built a new Department of Medicinal Chemistry at Cambridge University, UK, and greatly expanded his researches into the technology and applications of magnetic resonance imaging (MRI) and zero quantum NMR. MRI technology was applied both to medical problems such as the characterization of cartilage degeneration in knee joints, the measurement of ventricular function, lipid localization in animal models of atherosclerosis, paramagnetic metal complexes of polysaccharides as contrast agents, and studies of many other anatomical features, but also to several aspects of materials analysis, including food analyses, process control, and the elucidation of such physical phenomena as the flow of liquids through porous media, defects in concrete, and the visualization of fungal damage to wood. Professor Hall's many publications, patents, lectures, and honors and awards are described, and also his successful effort to keep the Asilomar facility in Pacific Grove, California as the alternating venue for the annual Experimental NMR Conference. Two memorial services for Professor Hall are remembered. Copyright © 2011 Elsevier Inc. All rights reserved.

Planes of phenomenological experience: The psychology of deafness as an early example of American Gestalt psychology, 1928-1940.

PubMed

Schmidt, Marion A

2017-11-01

When, in 1928, the Clarke School for the Deaf in Northampton, Massachusetts, opened a psychological research division, it was nothing unusual in a time fascinated with the sciences of education. Yet with its longstanding ties to Northampton's Smith College, the school was able to secure the collaboration of eminent Gestalt psychologist Kurt Koffka, who, in turn, engaged 2 more German-speaking emigrants, Margarete Eberhardt and social psychologist Fritz Heider, and Heider's American wife Grace Moore Heider. This collaboration has seen little attention from historians, who have treated Koffka's and Heider's time in Northampton as a transitory phase. I argue, however, that their research on deafness adds to the history of emigration and knowledge transfer between European and American Schools of psychology, and to historical understanding of the interrelation of Gestalt, child, and social psychology. Professionals in child studies and developmental psychology were keenly interested in the holistic and introspective approach Gestalt psychology offered. Deaf children were considered a particularly fascinating research population for exploring the relationship between thought and language, perception and development, Gestalt, and reality. At the Clarke School, Grace Moore Heider was among the first Americans to apply Gestalt principles to child psychology. In a time in which pejorative eugenic beliefs dominated professional perceptions of disability, the Heiders' groundbreaking work defined the deaf as a social and phenomenological minority. This was in opposition to dominant beliefs in deaf education, yet it points to early roots of a social model of deafness and disability, which historians usually locate in 1960s and '70s activism.

Two mooring dolphin concept for exposed tanker terminals

The conventional design of a tanker terminal provides for two or more mooring dolphins on each side of the breasting dolphins. Head and stern lines are attached to the outer mooring dolphins and breast lines to the inner mooring dolphins. In exposed locations, the expense of construction may be significantly reduced if a way can be found to reduce the number of mooring dolphins required for the safe mooring of ships at a fixed berth. A study based on plans for a proposed terminal for tankers from 25,000 to 100,000 dwt in the Bay of Fundy in eastern Canada considersmore » the possibility of reducing the total number of mooring dolphins from four to two.

Since July 2004, its surface has been imaged by the Cassini ISS cameras at resolutions between 200 and 500 m/pxl. We present results from our ongoing work to define and map geologic units in camera images obtained preferentially during Cassini’s Equinox and Solstice mission phases. In the majority of Tethys’ surface area a densely cratered plains unit [1][2][3][this work] is abundant. The prominent graben system of Ithaca Chasma is mapped as fractured cratered plains. Impact crater and basin materials can be subdivided into three degradational classes. Odysseus is a fresh large impact basin younger than Ithaca Chasma according to crater counts [4]. Heavily degraded craters and basins occur in the densely cratered plains unit. A smooth, less densely cratered plains unit in the trailing hemisphere was previously identified by [2] but mapping of its boundaries is difficult due to varying viewing geometries of ISS images. To the south of Odysseus, we identified a cratered plains unit not seen in Voyager data, characterized by remnants of highly degraded large craters superimposed by younger fresher craters with a lower crater density compared to the densely cratered plains unit. Its distinct linear northern contact with the densely cratered plains suggests a tectonic origin. Sets of minor fractures can be distinguished in the densely cratered plains, and locally, features of mass wasting can be observed. References: [1] Smith B. A. et al. (1981), Science 212, 163-191.

A Behavioral Analysis of Morality and Value

PubMed Central

2013-01-01

Morality has long been conceived as divinely instituted, so otherworldly, rules meant not to describe or explain behavior but to guide it towards an absolute good. The philosophical formulation of this theory by Plato was later grafted onto Christian thought by Augustine and Aquinas. The equally ancient theory of the Greek sophist Protagoras (that the good is relative to personal preferences and morality to man-made social customs) was forgotten until revived in the 18th and 19th centuries by such empiricists as David Hume and J. S. Mill. Then it was dismissed again in the 20th century by G. E. Moore and W. D. Ross as naturalistic fallacy, that is, conflation of what is with what ought to be. However, those who took this dismissive attitude themselves made the reverse mistake of conflating what ideally ought to be with what actually is. In other words, they mistook ideals for actualities. As B. F. Skinner (1971) said in Beyond Freedom and Dignity, sorting things out requires behaviorist parsing of the good (the personally reinforcing) and duty (the socially reinforced). PMID:28018035

Cabled-observatory Regional Circulation Moorings on the Endeavour segment of the Juan de Fuca Ridge

NASA Astrophysics Data System (ADS)

Mihaly, S. F.

2011-12-01

In September of 2010, one of four moorings was deployed on the Endeavour node of the NEPTUNE Canada cabled-observatory network. The installation included the laying of a 7km cable from the node to the mooring site in the axial valley about 3km north of the Main Endeavour Vent Field over extraordinary bathymetry. This September, three more cables and secondary junction boxes will be deployed to support the three additional moorings that complete the regional circulation array. The cable-laying is facilitated by the Canadian Scientific Submersible Facility's ROV ROPOS and a remotely operated cable-laying system, whereas the actual deployment of the moorings is a two ship operation. The CCGS John P. Tully lowers the mooring anchor first, while the RV Thomas G. Thompson supports the ROV operations which navigate the mooring to underwater mateable cable end. Precise navigation is needed because there are few areas suitable for placement of the junction boxes. Scientifically, the moorings are designed and located to best constrain the hydrothermally driven circulation within the rift valley, the regional circulation can then be used as a proxy measurement for hydrothermal fluxes. Each mooring carries a current meter/ ctd pair at 4, 50, 125, and 200m, with an upward looking ADCP at 250m. The northern moorings are located between the Hi-Rise and Salty Dawg fields about 700m apart in the ~1km wide rift valley and the southern moorings are located south of the Mothra vent field. Here we present initial results from the four mooring array.

Probabilistic analysis and fatigue damage assessment of offshore mooring system due to non-Gaussian bimodal tension processes

NASA Astrophysics Data System (ADS)

Chang, Anteng; Li, Huajun; Wang, Shuqing; Du, Junfeng

2017-08-01

Both wave-frequency (WF) and low-frequency (LF) components of mooring tension are in principle non-Gaussian due to nonlinearities in the dynamic system. This paper conducts a comprehensive investigation of applicable probability density functions (PDFs) of mooring tension amplitudes used to assess mooring-line fatigue damage via the spectral method. Short-term statistical characteristics of mooring-line tension responses are firstly investigated, in which the discrepancy arising from Gaussian approximation is revealed by comparing kurtosis and skewness coefficients. Several distribution functions based on present analytical spectral methods are selected to express the statistical distribution of the mooring-line tension amplitudes. Results indicate that the Gamma-type distribution and a linear combination of Dirlik and Tovo-Benasciutti formulas are suitable for separate WF and LF mooring tension components. A novel parametric method based on nonlinear transformations and stochastic optimization is then proposed to increase the effectiveness of mooring-line fatigue assessment due to non-Gaussian bimodal tension responses. Using time domain simulation as a benchmark, its accuracy is further validated using a numerical case study of a moored semi-submersible platform.

Mooring line damping estimation for a floating wind turbine.

2014-01-01

The dynamic responses of mooring line serve important functions in the station keeping of a floating wind turbine (FWT). Mooring line damping significantly influences the global motions of a FWT. This study investigates the estimation of mooring line damping on the basis of the National Renewable Energy Laboratory 5 MW offshore wind turbine model that is mounted on the ITI Energy barge. A numerical estimation method is derived from the energy absorption of a mooring line resulting from FWT motion. The method is validated by performing a 1/80 scale model test. Different parameter changes are analyzed for mooring line damping induced by horizontal and vertical motions. These parameters include excitation amplitude, excitation period, and drag coefficient. Results suggest that mooring line damping must be carefully considered in the FWT design.

Moor mud applications in the form of packs and baths are widely used therapeutically as part of balneotherapy. They are commonly given as therapy for musculoskeletal disorders, with their thermo-physical effects being furthest studied. Moor baths are one of the key therapeutic elements in our recently developed and evaluated 3-week prevention program for subjects with high stress level and increased risk of developing a burnout syndrome. An embedded pilot study add-on to this core project was carried out to assess the relaxing effect of a single moor bath. During the prevention program, 78 participants received a total of seven moor applications, each consisting of a moor bath (42 °C, 20 min, given between 02:30 and 05:20 p.m.) followed by resting period (20 min). Before and after the first moor application in week 1, and the penultimate moor application in week 3, salivary cortisol was collected, blood pressure and heart rate were measured, and mood state (Multidimensional Mood State Questionnaire) was assessed. A Friedman test of differences among repeated measures was conducted. Post hoc analyses were performed using the Wilcoxon signed-rank test. A significant decrease in salivary cortisol concentration was seen between pre- and post-moor bath in week 1 ( Z = -3.355, p = 0.0008). A non-significant decrease was seen between pre- and post-moor bath in week 3. Mood state improved significantly after both moor baths. This pilot study has provided initial evidence on the stress-relieving effects of single moor baths, which can be a sensible and recommendable therapeutic element of multimodal stress-reducing prevention programs. The full potential of moor baths still needs to be validated. A randomized controlled trial should be conducted comparing this balneo-therapeutic approach against other types of stress reduction interventions.

Rocking the Boat: Damage to Eelgrass by Swinging Boat Moorings.

2017-01-01

Seagrass meadows commonly reside in shallow sheltered embayments typical of the locations that provide an attractive option for mooring boats. Given the potential for boat moorings to result in disturbance to the seabed due to repeated physical impact, these moorings may present a significant threat to seagrass meadows. The seagrass Zostera marina (known as eelgrass) is extensive across the northern hemisphere, forming critical fisheries habitat and creating efficient long-term stores of carbon in sediments. Although boat moorings have been documented to impact seagrasses, studies to date have been conducted on the slow growing Posidonia species' rather than the fast growing and rapidly reproducing Z. marina that may have a higher capacity to resist and recover from repeated disturbance. In the present study we examine swinging chain boat moorings in seagrass meadows across a range of sites in the United Kingdom to determine whether such moorings have a negative impact on the seagrass Zostera marina at the local and meadow scale. We provide conclusive evidence from multiple sites that Z. marina is damaged by swinging chain moorings leading to a loss of at least 6 ha of United Kingdom seagrass. Each swinging chain mooring was found to result in the loss of 122 m 2 of seagrass. Loss is restricted to the area surrounding the mooring and the impact does not appear to translate to a meadow scale. This loss of United Kingdom seagrass from boat moorings is small but significant at a local scale. This is because it fragments existing meadows and ultimately reduces their resilience to other stressors. Boat moorings are prevalent in seagrass globally and it is likely this impairs their ecosystem functioning. Given the extensive ecosystem service value of seagrasses in terms of factors such as carbon storage and fish habitat such loss is of cause for concern. This indicates the need for the widespread use of seagrass friendly mooring systems in and around seagrass.

Altered fish community and feeding behaviour in close proximity to boat moorings in an urban estuary.

PubMed

Lanham, Brendan S; Vergés, Adriana; Hedge, Luke H; Johnston, Emma L; Poore, Alistair G B

2018-04-01

Coastal urbanization has led to large-scale transformation of estuaries, with artificial structures now commonplace. Boat moorings are known to reduce seagrass cover, but little is known about their effect on fish communities. We used underwater video to quantify abundance, diversity, composition and feeding behaviour of fish assemblages on two scales: with increasing distance from moorings on fine scales, and among locations where moorings were present or absent. Fish were less abundant in close proximity to boat moorings, and the species composition varied on fine scales, leading to lower predation pressure near moorings. There was no relationship at the location with seagrass. On larger scales, we detected no differences in abundance or community composition among locations where moorings were present or absent. These findings show a clear impact of moorings on fish and highlight the importance of fine-scale assessments over location-scale comparisons in the detection of the effects of artificial structures.

The quasi-static and dynamic mooring modules of the open-source aero-hydro-servo-elastic wind turbine simulation software, FAST v8, have previously been verified and validated, but only for mooring arrangements consisting of single lines connecting each fairlead and anchor. This paper extends the previous verification and validation efforts to focus on the multisegmented mooring capability of the FAST v8 modules: MAP++, MoorDyn, and the OrcaFlex interface. The OC3-Hywind spar buoy system tested by the DeepCwind consortium at the MARIN ocean basin, which includes a multisegmented bridle layout of the mooring system, was used for the verification and validation activities.

Fish production is important for the economy in fishing community and for ensuring food security. Climate change will lead a threat to fish productivity. Therefore, a solution offered is to cultivate certain fish, especially those with high economic value by using offshore aquaculture technology. A Sea Station cage is one of the offshore aquaculture cage model that has been used in some locations. As a floating structure, the Sea Station cage need a mooring system to maintain its position. This paper presents the selection analysis of the mooring system designs of the Sea Station cage model that it is suitable with Indonesia Ocean. There are 3 mooring configurations that are linear array, rectangular array, and 4 points mooring type. The nylon mooring rope type has been selected to be used on the 3 mooring configurations and the rope has a diameter of 104 mm with a breaking force of 2.3 MN. Based on results from comparing the 3 mooring configurations, the best mooring configuration is linear array with the tension on the rope of 217 KN and has the safety factor of 0.2 based on DNVGL OS-E301

Parameters sensitivity on mooring loads of ship-shaped FPSOs

The work in this paper is focused on special assessment and evaluation of mooring system of ship-shaped FPSO unit. In particular, the purpose of the study is to find the impact on mooring loads for the variation in different parameters using MIMOSA software. First, a selected base case was designed for an intact mooring system in a typical ultimate limit state (ULS) condition, and then the sensitivity to mooring loads on parameters e.g. location of the turret, analysis method (quasi-static vs. dynamic analysis), low-frequency damping level in the surge, pretension and drag coefficients on chain and steel wire has been performed. It is found that mooring loads change due to the change of these parameters. Especially, pretension has a large impact on the maximum tension of mooring lines and low-frequency damping can change surge offset significantly.

Evolutionary ethics from Darwin to Moore.

PubMed

Allhoff, Fritz

2003-01-01

Evolutionary ethics has a long history, dating all the way back to Charles Darwin. Almost immediately after the publication of the Origin, an immense interest arose in the moral implications of Darwinism and whether the truth of Darwinism would undermine traditional ethics. Though the biological thesis was certainly exciting, nobody suspected that the impact of the Origin would be confined to the scientific arena. As one historian wrote, 'whether or not ancient populations of armadillos were transformed into the species that currently inhabit the new world was certainly a topic about which zoologists could disagree. But it was in discussing the broader implications of the theory...that tempers flared and statements were made which could transform what otherwise would have been a quiet scholarly meeting into a social scandal' (Farber 1994, 22). Some resistance to the biological thesis of Darwinism sprung from the thought that it was incompatible with traditional morality and, since one of them had to go, many thought that Darwinism should be rejected. However, some people did realize that a secular ethics was possible so, even if Darwinism did undermine traditional religious beliefs, it need not have any effects on moral thought. Before I begin my discussion of evolutionary ethics from Darwin to Moore, I would like to make some more general remarks about its development. There are three key events during this history of evolutionary ethics. First, Charles Darwin published On the Origin of the Species (Darwin 1859). Since one did not have a fully developed theory of evolution until 1859, there exists little work on evolutionary ethics until then. Shortly thereafter, Herbert Spencer (1898) penned the first systematic theory of evolutionary ethics, which was promptly attacked by T.H. Huxley (Huxley 1894). Second, at about the turn of the century, moral philosophers entered the fray and attempted to demonstrate logical errors in Spencer's work; such errors were alluded to but never fully brought to the fore by Huxley. These philosophers were the well known moralists from Cambridge: Henry Sidgwick (Sidgwick 1902, 1907) and G.E. Moore (Moore 1903), though their ideas hearkened back to David Hume (Hume 1960). These criticisms were so strong that the industry of evolutionary ethics was largely abandoned (though with some exceptions) for many years. Third, E.O. Wilson, a Harvard entomologist, published Sociobiology: The New Synthesis in 1975 (Wilson E.O. 1975), which sparked renewed interest in evolutionary ethics and offered new directions of investigation. These events suggest the following stages for the history of evolutionary ethics: development, criticism and abandonment, revival. In this paper, I shall focus on the first two stages, since those are the ones on which the philosophical merits have already been largely decided. The revival stage is still in progress and we shall eventually find out whether it was a success.

Motion and dynamic responses of a semisubmersible in freak waves

NASA Astrophysics Data System (ADS)

Li, Xin; Deng, Yan-fei; Li, Lei; Tian, Xin-liang; Li, Jun

2017-12-01

The present research aims at clarifying the effects of freak wave on the motion and dynamic responses of a semisubmersible. To reveal the effects of mooring stiffness, two mooring systems were employed in the model tests and time-domain simulations. The 6-DOF motion responses and mooring tensions have been measured and the 3-DOF motions of fairleads were calculated as well. From the time series, trajectories and statistics information, the interactions between the freak wave and the semisubmersible have been demonstrated and the effects of mooring stiffness have been identified. The shortage of numerical simulations based on 3D potential flow theory is presented. Results show that the freak wave is likely to cause large horizontal motions for soft mooring system and to result in extremely large mooring tensions for tight mooring system. Therefore, the freak wave is a real threat for the marine structure, which needs to be carefully considered at design stage.

Turbulence Measurements from Compliant Moorings. Part II: Motion Correction

Kilcher, Levi F.; Thomson, Jim; Harding, Samuel

2017-06-01

Acoustic Doppler velocimeters (ADVs) are a valuable tool for making highprecision measurements of turbulence, and moorings are a convenient and ubiquitous platform for making many kinds of measurements in the ocean. However—because of concerns that mooring motion can contaminate turbulence measurements and acoustic Doppler profilers are relatively easy to deploy—ADVs are not frequently deployed from moorings. This work details a method for measuring turbulence using moored ADVs that corrects for mooring motion using measurements from inertial motion sensors. Three distinct mooring platforms were deployed in a tidal channel with inertial motion-sensor-equipped ADVs. In each case, the motion correction based onmore » the inertial measurements dramatically reduced contamination from mooring motion. The spectra from these measurements have a shape that is consistent with other measurements in tidal channels, and have a f^(5/3) slope at high frequencies—consistent with Kolmogorov’s theory of isotropic turbulence. Motion correction also improves estimates of cross-spectra and Reynold’s stresses. Comparison of turbulence dissipation with flow speed and turbulence production indicates a bottom boundary layer production-dissipation balance during ebb and flood that is consistent with the strong tidal forcing at the site. These results indicate that inertial-motion-sensor-equipped ADVs are a valuable new tool for measuring turbulence from moorings.« less

Analysis and design of trial well mooring in deepwater of the South China Sea

Mooring systems play an important role for semi-submersible rigs that drill in deepwater. A detailed analysis was carried out on the mooring of a semi-submersible rig that conducted a trial well drilling at a deepwater location in the South China Sea in 2009. The rig was 30 years old and had a shallow platform with a designed maximum operating water depth of 457 m. Following the mooring analysis, a mooring design was given that requires upgrading of the rig's original mooring system. The upgrade included several innovations, such as installing eight larger anchors, i.e. replacing the original anchors and inserting an additional 600 m of steel wires with the existing chains. All this was done to enhance the mooring capability of the rig in order for the rig to be held in position to conduct drilling at a water depth of 476 m. The overall duration of the drilling was 50 days and the upgraded mooring system proved to be efficient in achieving the goal of keeping the rig stationary while it was drilling the trial well in the South China Sea. This successful campaign demonstrates that an older semi-submersible rig can take on drilling in deep water after careful design and proper upgrading and modification to the original mooring system.

As Arctic regions are projected to strongly reflect the impacts of a changing climate, an effort is underway to make sustained, year-round measurements of concurrent physical and biogeochemical parameters in the Arctic. Deploying highly instrumented year-round moorings in the water is no simple feat, given harsh Arctic conditions that include the presence of sea ice and deep ice keels during much of the year. Enter the late-breaking ecosystem mooring located in the northeast Chukchi Sea. This mooring complements established biophysical moorings elsewhere in the northern Bering and Chukchi seas, including those maintained by NOAA-PMEL (M8), UW-APL (Bering Strait) and JAMSTEC moorings. (southern Chukchi and Barrow Canyon). The mooring described here is located on the southern flank of Hanna Shoal and provides a multi-disciplinary approach to year-round observations within a biological hotspot. The Chukchi Ecosystem Mooring is equipped with a sensor suite aimed to monitor and document the state of ocean acidification, nutrient and carbon cycles, particles, waves, currents and physical properties, and even passive and active acoustic monitoring for zooplankton, fish, and marine mammals. Having the simultaneous interdisciplinary measurements provides data valuable to an ecosystem-based approach to research and resource management. The fully outfitted observatory is providing an unprecedented view into the mechanistic workings of the Chukchi Shelf Ecosystem. The first mooring was deployed in September 2014 and recovered in August 2015. The August 2015 deployment consisted of three moorings, each with incremental sensor packages to complete the ecosystem sensor suite. The mooring construction and instrumentation are described in detail, including introduction to the advances in sensor technologies that enable such deployments. Year one data recovery summaries and plots are provided to demonstrate the capabilities.

The main conclusions from the work carried out under this contract are: An ordinary seafarer can learn by training on a simulator, to moor large tanker vessels to the Hydrostatic Mooring, safely and quickly, in all weather conditions up to storms generating waves with a significant wave height of 8 m. Complete conceptual design of the Hydrostatic Mooring buoy was carried out which proved that the buoy could be constructed entirely from commercially available standard components and materials. The design is robust, and damage resistant. The mooring tests had a 100% success rate from the point of view of themore » buoy being securely attached and moored to the vessel following every mooring attempt. The tests had an 80% success rate from the point of view of the buoy being adequately centered such that petroleum transfer equipment on the vessel could be attached to the corresponding equipment on the buoy. The results given in Table 3-2 of the mooring tests show a consistently improving performance from test to test by the Captain that performed the mooring operations. This is not surprising, in view of the fact that the Captain had only three days of training on the simulator prior to conducting the tests, that the maneuvering required is non-standard, and the test program itself lasted four days. One conclusion of the test performance is that the Captain was not fully trained at the initiation of the test. It may therefore be concluded that a thoroughly trained navigator would probably be able to make the mooring such that the fluid transfer equipment can be connected with reliability in excess of 90%. Considering that the typical standard buoy has enough power aboard to make eight mooring attempts, this implies that the probability that the mooring attempt should fail because of the inability to connect the fluid transfer equipment is of the order of 10{sup {minus}8}. It may therefore be concluded that the mooring operation between a Hydrostatic Mooring and a large tanker vessel can be carried out with near absolute reliability in all sea states up to a sea state where the significant wave height is 8 m.« less

Mooring concepts appropriate for maritime patrol airship (MPA) vehicles are investigated. The evolution of ground handling systems and procedures for all airship types is reviewed to ensure that appropriate consideration is given to past experiences. A tri-rotor maritime patrol airship is identified and described. Wind loads on a moored airship and the effects of these loads on vehicle design are analyzed. Several mooring concepts are assessed with respect to the airship design, wind loads, and mooring site considerations. Basing requirements and applicability of expeditionary mooring also are addressed.

An experimental study of the effect of mooring systems on the dynamics of a SPAR buoy-type floating offshore wind turbine

2015-09-01

An experimental study of the effect of mooring systems on the dynamics of a SPAR buoy-type floating offshore wind turbine is presented. The effects of the Center of Gravity (COG), mooring line spring constant, and fair-lead location on the turbine's motion in response to regular waves are investigated. Experimental results show that for a typical mooring system of a SPAR buoy-type Floating Offshore Wind Turbine (FOWT), the effect of mooring systems on the dynamics of the turbine can be considered negligible. However, the pitch decreases notably as the COG increases. The COG and spring constant of the mooring line have a negligible effect on the fairlead displacement. Numerical simulation and sensitivity analysis show that the wind turbine motion and its sensitivity to changes in the mooring system and COG are very large near resonant frequencies. The test results can be used to validate numerical simulation tools for FOWTs.

2016-04-01

The absolute level of the global net radiation flux (NRF) is fixed at the level of [0.5-1.0] Wm-2 based on the ocean heat content measurements [1]. The space derived global NRF is at the same order of magnitude than the ocean [2]. Considering the atmosphere has a negligible effects on the global NRF determination, the surface global NRF is consistent with the values determined from space [3]. Instead of studying the absolute level of the global NRF, we focus on the interannual variation of global net radiation flux, which were derived from the PICARD-BOS experiment and its comparison with values over the same period but obtained from the NASA-CERES system and inferred from the ocean heat content survey by ARGO network.

Marine renewable energy devices require mooring and foundation systems that suitable in terms of device operation and are also robust and cost effective. In the initial stages of mooring and foundation development a large number of possible configuration permutations exist. Filtering of unsuitable designs is possible using information specific to the deployment site (i.e. bathymetry, environmental conditions) and device (i.e. mooring and/or foundation system role and cable connection requirements). The identification of a final solution requires detailed analysis, which includes load cases based on extreme environmental statistics following certification guidance processes. Static and/or quasi-static modelling of the mooring and/or foundationmore » system serves as an intermediate design filtering stage enabling dynamic time-domain analysis to be focused on a small number of potential configurations. Mooring and foundation design is therefore reliant on logical decision making throughout this stage-gate process. The open-source DTOcean (Optimal Design Tools for Ocean Energy Arrays) Tool includes a mooring and foundation module, which automates the configuration selection process for fixed and floating wave and tidal energy devices. As far as the authors are aware, this is one of the first tools to be developed for the purpose of identifying potential solutions during the initial stages of marine renewable energy design. While the mooring and foundation module does not replace a full design assessment, it provides in addition to suitable configuration solutions, assessments in terms of reliability, economics and environmental impact. This article provides insight into the solution identification approach used by the module and features the verification of both the mooring system calculations and the foundation design using commercial software.

When I studied the subject in 1950 in the late Claude K. Deischer's class at the University of Pennsylvania, our text was Frank J. Moore's A History of Chemistry (1918; 3rd ed., 1939), one of the few books, all written by practicing chemists, then available in English. Now, paradoxically, at a time when such classes are no longer a standard part of the usual undergraduate curriculum, we are treated to a plethora of histories, most written by professional historians of science. In two recent years alone four histories have appeared: David M. Knight's Ideas in Chemistry: A History of the Science (Rutgers University Press, 1992), William H. Brock's The History of Chemistry (Chapman & Hall, 1992), William H.

The book under review here is a felicitous English translation of the last-named volume.

Turbulence Measurements from Compliant Moorings. Part II: Motion Correction

DOE PAGES

Kilcher, Levi F.; Thomson, Jim; Harding, Samuel; ...

2017-06-20

Acoustic Doppler velocimeters (ADVs) are a valuable tool for making high-precision measurements of turbulence, and moorings are a convenient and ubiquitous platform for making many kinds of measurements in the ocean. However, because of concerns that mooring motion can contaminate turbulence measurements and that acoustic Doppler profilers make middepth velocity measurements relatively easy, ADVs are not frequently deployed from moorings. This work demonstrates that inertial motion measurements can be used to reduce motion contamination from moored ADV velocity measurements. Three distinct mooring platforms were deployed in a tidal channel with inertial-motion-sensor-equipped ADVs. In each case, motion correction based on themore » inertial measurements reduces mooring motion contamination of velocity measurements. The spectra from these measurements are consistent with other measurements in tidal channels and have an f –5/3 slope at high frequencies - consistent with Kolmogorov's theory of isotropic turbulence. Motion correction also improves estimates of cross spectra and Reynolds stresses. A comparison of turbulence dissipation with flow speed and turbulence production indicates a bottom boundary layer production-dissipation balance during ebb and flood that is consistent with the strong tidal forcing at the site. Finally, these results indicate that inertial-motion-sensor-equipped ADVs are a valuable new tool for making high-precision turbulence measurements from moorings.« less

A review of the evolution of ground handling systems and procedures for all airship types is presented to ensure that appropriate consideration is given to past experiences. Two buoyant quad rotor designs are identified and described. An analysis of wind loads on a moored airship and the effects of these loads on vehicle design is provided. Four mooring concepts are assessed with respect to the airship design, wind loads and mooring site considerations. Basing requirements and applicability of expeditionary mooring at various operational scenarios are addressed.

Selection and optimization of mooring cables on floating platform for special purposes

Ma, Guang-ying; Yao, Yun-long; Zhao, Chen-yao

2017-08-01

This paper studied a new type of assembled marine floating platform for special purposes. The selection and optimization of mooring cables on the floating platform are studied. By using ANSYS AQWA software, the hydrodynamic model of the platform was established to calculate the time history response of the platform motion under complex water environments, such as wind, wave, current and mooring. On this basis, motion response and cable tension were calculated with different cable mooring states under the designed environmental load. Finally, the best mooring scheme to meet the cable strength requirements was proposed, which can lower the motion amplitude of the platform effectively.

Fatigue analysis of the bow structure of FPSO

NASA Astrophysics Data System (ADS)

Hu, Zhi-Qiang; Gao, Zhen; Gu, Yong-Ning

2003-06-01

The bow structure of FPSO moored by the single mooring system is rather complicated. There are many potential hot spots in connection parts of structures between the mooring support frame and the forecastle. Mooring forces, which are induced by wave excitation and transferred by the YOKE and the mooring support frame, may cause fatigue damage to the bow structure. Different from direct wave-induced-forces, the mooring force consists of wave frequency force (WF) and 2nd draft low frequency force (LF)[3], which are represented by two sets of short-term distribution respectively. Based on two sets of short-term distribution of mooring forces obtained by the model test, the fatigue damage of the bow structure of FPSO is analyzed, with emphasis on two points. One is the procedure and position selection for fatigue check, and the other is the application of new formulae for the calculation of accumulative fatigue damage caused by two sets of short-term distribution of hot spot stress range. From the results distinguished features of fatigue damage to the FPSO’s bow structure can be observed.

Study on global performances and mooring-induced damping of a semi-submersible

NASA Astrophysics Data System (ADS)

Xiong, Ling-zhi; Yang, Jian-min; Lv, Hai-ning; Zhao, Wen-hua; Kou, Yu-feng

2016-10-01

The harsh environmental conditions bring strong nonlinearities to the hydrodynamic performances of the offshore floating platforms, which challenge the reliable prediction of the platform coupled with the mooring system. The present study investigates a typical semi-submersible under both the operational and the survival conditions through numerical and experimental methods. The motion responses, the mooring line tensions, and the wave loads on the longitudinal mid-section are investigated by both the fully non-linearly coupled numerical simulation and the physical experiment. Particularly, in the physical model test, the wave loads distributed on the semi-submersible's mid-section were measured by dividing the model into two parts, namely the port and the starboard parts, which were rigidly connected by three six-component force transducers. It is concluded that both the numerical and physical model can have good prediction of the semi-submersible's global responses. In addition, an improved numerical approach is proposed for the estimation of the mooring-induced damping, and is validated by both the experimental and the published results. The characteristics of the mooring-induced damping are further summarized in various sea states, including the operational and the survival environments. In order to obtain the better prediction of the system response in deep water, the mooring-induced damping of the truncated mooring lines applied in the physical experiment are compensated by comparing with those in full length. Furthermore, the upstream taut and the downstream slack mooring lines are classified and investigated to obtain the different mooring line damping performances in the comparative study.

Werther Goes Viral: Suicidal Contagion, Anti-Vaccination, and Infectious Sympathy.

PubMed

Faubert, Michelle

The fear that suicidality could spread through textual contagion-that textually represented suicide could enter the reader's mind and cause self-destruction-took hold long before Émile Durkheim theorized it in the Victorian period. This article argues that the fear of suicidal contagion and the horror of vaccination, both of which raged in Britain in the long eighteenth century, were linked to ideas about sympathy and the importation of the Other into the Self. With reference to the psychoanalytic notions of extimité and étrangerété; the eighteenth-century medical theories of William Rowley and Edward Jenner; the philosophy of "sympathy," as adumbrated in the work of John Locke, Adam Smith, David Hume and Edmund Burke; and two key novels of sensibility (Jean-Jacques Rousseau's Julie and Johann Wolfgang von Goethe's The Sorrows of Young Werther), this article examines the root of a belief that exists even today: that, in a suicidal process, the invading Other could become the Self and, Trojan horse-style, destroy it from the inside.

Freitag, H. Paul

1994-01-01

During the Coupled Ocean Atmosphere Response Experiment (COARE) six TAO moorings were equipped with optical rain gauges (ORG's). In late 1993 moorings deployed on the equator at 154E and 157.5E were recovered and not redeployed as they were augmentations to the TAO array for COARE only. In December 1993, four TAO moorings were equipped with ORG's: one each at 2N, 156E and 2S, 156E and ORG doublets on the equator at 0, 156E and 0, 165E. The 2N, 156E mooring has been lost. By the end of April all sites will have been serviced and six refurbished sensors will again be deployed in the same locations.

McEntee, Jarlath

Ocean Renewable Power Company's OCGen Module Mooring Project provided an extensive research, design, development, testing and data collection effort and analysis conducted with respect to a positively buoyant, submerged MHK device secured to the seabed using a tensioned mooring system. Different analytic tools were evaluated for their utility in the design of submerged systems and their moorings. Deployment and testing of a prototype OCGen® system provided significant data related to mooring line loads and system attitude and station keeping. Mooring line loads were measured in situ and reported against flow speeds. The Project made a significant step in the developmentmore » of designs, methodologies and practices related to floating and mooring of marine hydrokinetic (MHK) devices. Importantly for Ocean Renewable Power Company, the Project provided a sound basis for advancing a technically and commercially viable OCGen® Power System. The OCGen® Power System is unique in the MHK industry and, in itself, offers distinct advantages of MHK devices that are secured to the seabed using fixed structural frames. Foremost among these advantages are capital and operating cost reductions and increased power extraction by allowing the device to be placed at the most energetic level of the water column.« less

Physical oceanographic data from the OTEC Punta Tuna, Puerto Rico Site, September 1979-June 1980

DOE Office of Scientific and Technical Information (OSTI.GOV)

Frye, D.; Davison, A.; Leavitt, K.

1981-01-01

The first results of an oceanographic measurement program being conducted off the southeast corner of Puerto Rico are presented. The study site is a proposed OTEC site and is located about 20 km off Punta Tuna. The objectives of the measurement program are to document the physical oceanography of the site as related to the engineering and environmental factors involved in OTEC design and operation. Oceanographic measurements include: (1) a subsurface mooring instrumented with five current, temperature, and pressure recorders; and (2) quarterly hydrographic cruises to measure salinity, temperature, and depth profiles on a grid of 33 stations in themore » vicinity of the mooring site. The first cruise, conducted between 16 and 21 June 1980, included the initial mooring deployment and a CTD (conductivity, temperature, and depth) and XBT (expendable bathythermograph) survey. The CTD/XBT measurements are presented. Also included are results of in situ current, temperature, and pressure measurements made during two previous programs. In September 1979, Coastal Marine Research (CMR) deployed a mooring at approximately the same site as the present mooring. Results from three of these instruments are included. The Naval Underwater Systems Center deployed a mooring at this site in February 1979 and partial results from one instrument on this mooring are also presented. (WHK)« less

Acoustic Doppler velocimeters (ADVs) are a valuable tool for making high-precision measurements of turbulence, and moorings are a convenient and ubiquitous platform for making many kinds of measurements in the ocean. However, because of concerns that mooring motion can contaminate turbulence measurements and that acoustic Doppler profilers make middepth velocity measurements relatively easy, ADVs are not frequently deployed from moorings. This work demonstrates that inertial motion measurements can be used to reduce motion contamination from moored ADV velocity measurements. Three distinct mooring platforms were deployed in a tidal channel with inertial-motion-sensor-equipped ADVs. In each case, motion correction based on themore » inertial measurements reduces mooring motion contamination of velocity measurements. The spectra from these measurements are consistent with other measurements in tidal channels and have an f –5/3 slope at high frequencies - consistent with Kolmogorov's theory of isotropic turbulence. Motion correction also improves estimates of cross spectra and Reynolds stresses. A comparison of turbulence dissipation with flow speed and turbulence production indicates a bottom boundary layer production-dissipation balance during ebb and flood that is consistent with the strong tidal forcing at the site. Finally, these results indicate that inertial-motion-sensor-equipped ADVs are a valuable new tool for making high-precision turbulence measurements from moorings.« less

PREFACE: E-MRS 2012 Spring Meeting, Symposium M: More than Moore: Novel materials approaches for functionalized Silicon based Microelectronics

NASA Astrophysics Data System (ADS)

Wenger, Christian; Fompeyrine, Jean; Vallée, Christophe; Locquet, Jean-Pierre

2012-12-01

More than Moore explores a new area of Silicon based microelectronics, which reaches beyond the boundaries of conventional semiconductor applications. Creating new functionality to semiconductor circuits, More than Moore focuses on motivating new technological possibilities. In the past decades, the main stream of microelectronics progresses was mainly powered by Moore's law, with two focused development arenas, namely, IC miniaturization down to nano scale, and SoC based system integration. While the microelectronics community continues to invent new solutions around the world to keep Moore's law alive, there is increasing momentum for the development of 'More than Moore' technologies which are based on silicon technologies but do not simply scale with Moore's law. Typical examples are RF, Power/HV, Passives, Sensor/Actuator/MEMS or Bio-chips. The More than Moore strategy is driven by the increasing social needs for high level heterogeneous system integration including non-digital functions, the necessity to speed up innovative product creation and to broaden the product portfolio of wafer fabs, and the limiting cost and time factors of advanced SoC development. It is believed that More than Moore will add value to society on top of and beyond advanced CMOS with fast increasing marketing potentials. Important key challenges for the realization of the 'More than Moore' strategy are: perspective materials for future THz devices materials systems for embedded sensors and actuators perspective materials for epitaxial approaches material systems for embedded innovative memory technologies development of new materials with customized characteristics The Hot topics covered by the symposium M (More than Moore: Novel materials approaches for functionalized Silicon based Microelectronics) at E-MRS 2012 Spring Meeting, 14-18 May 2012 have been: development of functional ceramics thin films New dielectric materials for advanced microelectronics bio- and CMOS compatible material systems piezoelectric films and nanostructures Atomic Layer Deposition (ALD) of oxides and nitrides characterization and metrology of very thin oxide layers We would like to take this opportunity to thank the Scientific Committee and Local Committee for bringing together a coherent and high quality Symposium at E-MRS 2012 Spring Meeting.

The familiar story of Moore's law is actually inaccurate. Here, this article corrects the story, leading to different projections for the future. Moore's law is a fluid idea whose definition changes over time. It thus doesn't have the ability to "end," as is popularly reported, but merely takes different forms as the semiconductor and computer industries evolve.

2009-10-01

We investigated the prevalence of genotypes/alleles of single nucleotide polymorphisms (SNP) and haplotypes defined by them in three genes in which variations are associated with venous thromboembolism in 80 Sinhalese, 80 Sri Lankan Tamils and 80 Moors in the Sri Lankan population and compared the SNP data with that of other populations in Southern India and haplotype data with that of HapMap populations. The genes and polymorphisms investigated were Methylenetetrahydrofolate reductase (MTHFR) - 677C>T (rs1801133), 1298A>C (rs1801131), 1317T>C, 1793G>A (rs2274976); Factor V (F5) - 1691G>A (rs6025) and 4070A>G (rs1800595); and prothrombin (F2) - 20210G>A (rs1799963). The polymorphisms were genotyped using PCR/RFLP methods. The prevalence of the variant alleles of each polymorphism in the Sinhalese, Tamils, and Moors was MTHFR 677T: Sinhalese - 13%, Tamils - 9%, Moors - 9%. 1317T>C: Sinhalese - 0%; Tamils - 0%; Moors - 0%. 1793A: Sinhalese - 19%, Tamils - 19%, Moors - 19%. F5 1691A: Sinhalese - 2%, Tamils - 3%, Moors - 2%. 4070G: Sinhalese - 6%, Tamils - 5%, Moors - 8%. F2 20210A: Sinhalese - 0%, Tamils - 0%, Moors - 0%. The frequencies observed were similar to data from other South Indian populations; the haplotype data showed haplotypes unique to the Sri Lankan population when compared to HapMap populations. rs9651118 was identified as a SNP that splits the haplotypes harbouring the functionally significant 677T allele in the MTHFR gene. This data would be useful in planning genetic association studies in the Sri Lankan population and in deciding on which genetic variants should be tested in a clinical genetic testing service.

Social isolation is associated with an increased risk for mental and physical health problems, especially among older persons living with HIV (PLWH). Thus, there is a need to better understand real-time temporal associations between social activity and mood- and health-related factors in this population to inform possible future interventions. This study aims to examine real-time relationships between social activity and mood, fatigue, and pain in a sample of older PLWH. A total of 20 older PLWH, recruited from the University of California, San Diego HIV Neurobehavioral Research Program in 2016, completed smartphone-based ecological momentary assessment (EMA) surveys 5 times per day for 1 week. Participants reported their current social activity (alone vs not alone and number of social interactions) and levels of mood (sadness, happiness, and stress), fatigue, and pain. Mixed-effects regression models were used to analyze concurrent and lagged associations among social activity, mood, fatigue, and pain. Participants (mean age 58.8, SD 4.3 years) reported being alone 63% of the time, on average, (SD 31.5%) during waking hours. Being alone was related to lower concurrent happiness (beta=-.300; 95% CI -.525 to -.079; P=.008). In lagged analyses, social activity predicted higher levels of fatigue later in the day (beta=-1.089; 95% CI -1.780 to -0.396; P=.002), and higher pain levels predicted being alone in the morning with a reduced likelihood of being alone as the day progressed (odds ratio 0.945, 95% CI 0.901-0.992; P=.02). The use of EMA elucidated a high rate of time spent alone among older PLWH. Promoting social activity despite the presence of pain or fatigue may improve happiness and psychological well-being in this population. ©Emily W Paolillo, Bin Tang, Colin A Depp, Alexandra S Rooney, Florin Vaida, Christopher N Kaufmann, Brent T Mausbach, David J Moore, Raeanne C Moore.

Nature in economic theories: Hans Immler traces recognition of the environment - and its neglect - in various classics

Labor and capital are usually considered as the primary factors of production, the costs of which are of utmost importance. In contrast, nature (including all natural resources), as the essential third factor, is disregarded. She is generally assumed to be always available, self-regenerating, and to be exploited without long-term costs. In other words, she is more or less viewed as a constant. Hans Immler's new treatise represents an important contribution in that he emphasized the role and function of the natural environment, and its neglect, in the formulation of theories of value and their long-term consequences on contemporary economic theoriesmore » and on the person and society. This essay traces Immler's evaluation with extensive quotations - especially with regard to Physiocracy and the classical economists - of nature's role and function, or their neglect, in the formulation of theories of value through the writings of Aristotle, St. Thomas Aquinas, William Petty, John Locke, Adam Smith, David Ricardo, Karl Marx, and others, - all dealt with in Part 1 of his book - and Francois Quesnay and the Physiocrats - the topic of Part 2.« less

A Reply to the Comment on "Assessing Discrepancies Between Previous Plate Kinematic Models of Mesozoic Iberia and Their Constraints" by Barnett-Moore Et Al.

Barnett-Moore, N.; Font, E.; Neres, M.

2017-12-01

We welcome the comments of van Hinsbergen et al. (2017) on the recent efforts of Barnett-Moore et al. (2016). Specifically, van Hinsbergen et al. (2017) raise concerns about two of the major conclusions made by Barnett-Moore et al. (2016). First, Barnett-Moore et al. (2016) choose to negate the Cretaceous Iberian paleomagnetic database as a viable plate kinematic constraint on the plate motions of Mesozoic Iberia. This conclusion, criticized by van Hinsbergen et al. (2017), was based on citing the previous efforts of Neres et al. (2012, 2013), which exposed several shortcomings, elaborated on below, within this data set. Second, van Hinsbergen et al. (2017) criticize Barnett-Moore et al. (2016) for dismissing mantle tomographic interpretations in support of a preserved Cretaceous Pyrenean "subducted slab" beneath northern Africa. Below, we have addressed each of these major criticisms from van Hinsbergen et al. (2017) in a two-section layout, similar to their comment above.

The Ocean Observatories Initiative air-sea flux mooring deployed at 54.08°S, 89.67°W, in the southeast Pacific sector of the Southern Ocean, is the farthest south long-term open ocean flux mooring ever deployed. Mooring observations (February 2015 to August 2017) provide the first in situ quantification of annual net air-sea heat exchange from one of the prime Subantarctic Mode Water formation regions. Episodic turbulent heat loss events (reaching a daily mean net flux of -294 W/m2) generally occur when northeastward winds bring relatively cold, dry air to the mooring location, leading to large air-sea temperature and humidity differences. Wintertime heat loss events promote deep mixed layer formation that lead to Subantarctic Mode Water formation. However, these processes have strong interannual variability; a higher frequency of 2 σ and 3 σ turbulent heat loss events in winter 2015 led to deep mixed layers (>300 m), which were nonexistent in winter 2016.

Infrastructure associated with coastal communities is likely to not only directly displace natural systems, but also leave environmental footprints' that stretch over multiple scales. Some coastal infrastructure will, there- fore, generate a hidden layer of habitat heterogeneity in sediment systems that is not immediately observable in classical impact assessment frameworks. We examine the hidden heterogeneity associated with one of the most ubiquitous coastal modifications; dense swing moorings fields. Using a model based geo-statistical framework we highlight the variation in sedimentology throughout mooring fields and reference locations. Moorings were correlated with patches of sediment with larger particle sizes, and associated metal(loid) concentrations in these patches were depressed. Our work highlights two important ideas i) mooring fields create a mosaic of habitat in which contamination decreases and grain sizes increase close to moorings, and ii) model- based frameworks provide an information rich, easy-to-interpret way to communicate complex analyses to stakeholders.

Moored offshore structures - evaluation of forces in elastic mooring lines

NASA Astrophysics Data System (ADS)

Crudu, L.; Obreja, D. C.; Marcu, O.

2016-08-01

In most situations, the high frequency motions of the floating structure induce important effects in the mooring lines which affect also the motions of the structure. The experience accumulated during systematic experimental tests and calculations, carried out for different moored floating structures, showed a complex influence of various parameters on the dynamic effects. Therefore, it was considered that a systematic investigation is necessary. Due to the complexity of hydrodynamics aspects of offshore structures behaviour, experimental tests are practically compulsory in order to be able to properly evaluate and then to validate their behaviour in real sea. Moreover the necessity to carry out hydrodynamic tests is often required by customers, classification societies and other regulatory bodies. Consequently, the correct simulation of physical properties of the complex scaled models becomes a very important issue. The paper is investigating such kind of problems identifying the possible simplification, generating different approaches. One of the bases of the evaluation has been found consideringtheresults of systematic experimental tests on the dynamic behaviour of a mooring chain reproduced at five different scales. Dynamic effects as well as the influences of the elasticity simulation for 5 different scales are evaluated together. The paper presents systematic diagrams and practical results for a typical moored floating structure operating as pipe layer based on motion evaluations and accelerations in waves.

Frontiers of More than Moore in Bioelectronics and the Required Metrology Needs

NASA Astrophysics Data System (ADS)

Guiseppi-Elie, Anthony; Kotanen, Christian; Wilson, A. Nolan

2011-11-01

Silicon's intersection with biology is a premise inherent in Moore's prediction. Distinct from biologically inspired molecular logic and storage devices (more Moore) are the integration of solid state electronic devices with the soft condensed state of the body (more than Moore). Developments in biomolecular recognition events per sq. cm parallel those of Moore's Law. However, challenges continue in the area of "More than Moore". Two grand challenge problems must be addressed—the biocompatibility of synthetic materials with the myriad of tissue types within the human body and the interfacing of solid state micro- and nano-electronic devices with the electronics of biological systems. Electroconductive hydrogels have been developed as soft, condensed, biomimetic but otherwise inherently electronically conductive materials to address the challenge of interfacing solid state devices with the electronics of the body, which is predominantly ionic. Nano-templated interfaces via the oriented immobilization of single walled carbon nanotubes (SWCNTs) onto metallic electrodes have engendered reagentless, direct electron transfer between biological redox enzymes and solid state electrodes. In addressing these challenges, metrology needs and opportunities are found in such widely diverse areas as single molecule counting and addressing, sustainable power requirements such as the development of implantable biofuel cells for the deployment of implantable biochips, and new manufacturing paradigms to address plura-biology needs on solid state devices.

Boating activities are one of the causes that threaten seagrass meadows and the ecosystem services they provide. Mechanical destruction of seagrass habitats may also trigger the erosion of sedimentary organic carbon (Corg) stocks, which may contribute to increasing atmospheric CO2. This study presents the first estimates of loss of Corg stocks in seagrass meadows due to mooring activities in Rottnest Island, Western Australia. Sediment cores were sampled from seagrass meadows and from bare but previously vegetated sediments underneath moorings. The Corg stores have been compromised by the mooring deployment from 1930s onwards, which involved both the erosion of existing sedimentary Corg stores and the lack of further accumulation of Corg. On average, undisturbed meadows had accumulated ~6.4 Kg Corg m−2 in the upper 50 cm-thick deposits at a rate of 34 g Corg m−2 yr−1. The comparison of Corg stores between meadows and mooring scars allows us to estimate a loss of 4.8 kg Corg m−2 in the 50 cm-thick deposits accumulated over ca. 200 yr as a result of mooring deployments. These results provide key data for the implementation of Corg storage credit offset policies to avoid the conversion of seagrass ecosystems and contribute to their preservation. PMID:26979407

The development of the Garden Banks block 388 FPF mooring system

DOE Office of Scientific and Technical Information (OSTI.GOV)

Dove, P.G.S.; Librino, F.; Scovell, D.C.

1995-12-01

This paper discusses work conducted during the design, procurement and installation of Enserch Exploration, Inc.`s Garden Banks 388 FPF mooring system. The design began with the execution of a trade-off study evaluating and comparing previously installed floating production moorings in the Gulf of Mexico, coupled with evaluation of new concepts and emphasis on cost effective solutions. The design effort involved dynamic analysis and wind tunnel and model tank testing, all in accordance with the newly completed API document RP 2FP1. Inspection of various components from the Placid GC-29 FPS moorings (installed in 1987 and recovered in 1990) determined that sectionsmore » of chain, jacketed spiral strand wire rope, submersible buoys and connectors could be reused with suitable refurbishment. The excellent condition of the rig`s onboard winching system also resulted in the reuse of the windlasses, with specified upgrades. Because a sufficient amount of used wire was not available, a bare spiral strand wire rope construction was adopted, including zinc anodes in the new sections, rather than jacketed strand. The lack of cost effective installation vessels in the Gulf of Mexico at the time of the installation bid posed challenges to Enserch. However, an innovative preset mooring installation scheme involving Heeremac`s SSCV Balder on its own moorings was adopted. Since the vessel was already in the Gulf of Mexico on contract for other projects, a cost effective contract was negotiated. The results of this effort led to considerable cost savings for Enserch, compared to conventional FPF mooring systems previously installed in the Gulf of Mexico.« less

The design and analysis of mooring system

NASA Astrophysics Data System (ADS)

Li, Yixuan

2017-05-01

In this paper, the force status and a design method of single chain mooring system for shallow sea observation network are studied. With treating the link of a chain, steel drum and steel pipe as a rigid body, the recurrence model is established by using Newton's first law and the law of Moment equilibrium theorem. Via the simplified calculation of dichotomy searching, we determine the design parameters of mooring system, such as anchor model, anchor chain length, heavy ball quality under different water flow and wind conditions. We apply MATLAB to simulate the internal steady state of the system in the fixed scheme, water depth of buoy and swimming area to meet the decision-making needs, providing an idea for the actual scheme design of mooring system.

Circulation on the West Antarctic Peninsula derived from 6 years of shipboard ADCP transects

NASA Astrophysics Data System (ADS)

Savidge, Dana K.; Amft, Julie A.

2009-10-01

Over the past 30 years, shelf circulation on the West Antarctic Peninsula (WAP) has been derived from hydrographic data with a reasonable level of confidence. However, with the exception of a very few drifter tracks and current-meter timeseries from moorings, direct velocity measurements have not previously been available. In this article, shelf and shelf-edge circulation is examined using a new velocity dataset, consisting of several years of acoustic Doppler current profiler transects, routinely collected along the ship tracks of the R/V Gould and the R/V Palmer since the fall of 1997. Initial processing and quality control is performed by Dr. Teresa Chereskin and Dr. Eric Firing, who then place the data in an archive accessible by public website, resulting in the broad availability of the data for a variety of uses. In this study, gridded Eulerian means have been calculated to examine circulation on the shelf and slope off the South Shetland Islands, in Bransfield Strait, and on the shelf and slope south of these regions, including Marguerite Bay and the adjacent shelf and shelf-edge. Shelf-edge flow is northeastward in the study area from the offshore of northern Alexander Island to Smith Island, while a southward flowing shelf-edge feature, probably the shallow component of the polar slope current, appears between Elephant Island and Livingston Island. The shallow polar slope current appears to turn shoreward to pass through Boyd Strait between Smith and Livingston Islands. In Bransfield Strait, there is cyclonic circulation. The previously identified northeastward-flowing South Shetland Island jet is strong and present in all seasons, with a large barotropic component not revealed by the hydrography-based velocities derived in the past. On the shelf seaward of Adelaide, Anvers and Brabant Islands, the strong along-shelf Antarctic Peninsula coastal current flows southwestward, with strongest velocities in winter (June-September) off Anvers and Brabant Islands, but stronger in summer (December-March) off Adelaide Island. Seaward of Marguerite Bay, there is seaward flow in the upper 400 m of the water column over the southwest bank of Marguerite Trough, strongest in summer, and shoreward flow near the northeast bank and adjacent shallower shelf areas.

High Frequency, Long Time Series Measurements from the Bermuda Testbed Mooring in Support of SIMBIOS. Chapter 8

It has been recognized that optical moorings are important platforms for the validation of Sea-Viewing Wide Field-of-view Sensor (SeaWiFS). It was recommended that optical moorings be maintained in order to: (1) provide long-term time series comparisons between in situ and SeaWIFS measurements of normalized water-leaving radiance; (2) develop and test algorithms for pigment biomass and phytoplankton primary productivity; and (3) provide long-term, virtually continuous in situ observations which can be used to determine and optimize the accuracy of derived satellite products. These applications require the use of in situ radiometers for long periods of time to evaluate and correct for inherent satellite undersampling (aliasing and biasing) and degradation of satellite color sensors (e.g., drifts as experienced by the Coastal Zone Color Scanner). The Bermuda Testbed Mooring (BTM) program was initiated in 1994 at a site located about 80km southeast of Bermuda in waters of about 4530 m depth. In August 1997, with NASA's support, we started to provide the Sensor Intercomparison and Merger for Biological and Interdisciplinary Oceanic Studies (SIMBIOS) program with large volumes of high frequency, long-term time-series bio-optical data from the BTM for SeaWiFS satellite ocean color groundtruthing and algorithm development. This NASA supported portion of the BTM activity spanned three years and covered five BTM deployments. During these three years, the quality of radiometric data has improved dramatically. Excellent agreement between BTM moored data and both SeaWiFS and nearby ship profile radiometric data demonstrate that technical advances in the moored optical observations have reduced the major difficulties that moored platforms face: biofouling and less frequent calibration.

Admiralty Inlet Advanced Turbulence Measurements: May 2015

This data is from measurements at Admiralty Head, in Admiralty Inlet (Puget Sound) in May of 2015. The measurements were made using Inertial Motion Unit (IMU) equipped ADVs mounted on a 'StableMoor' (Manufacturer: DeepWater Buoyancy) buoy and a Tidal Turbulence Mooring (TTM). These platforms position ADV heads above the seafloor to make mid-depth turbulence measurements. The inertial measurements from the IMU allows for removal of mooring motion in post processing. The mooring and buoy motion has been removed from the stream-wise and vertical velocity signals (u, w). The lateral (v) velocity has some 'persistent motion contamination' due to mooring sway.more » The TTM was deployed with one ADV, it's position was: 48 09.145', -122 41.209' The StableMoor was deployed twice, the first time it was deployed in 'wing-mode' with two ADVs ('Port' and 'Star') at: 48 09.166', -122 41.173' The second StableMoor deployment was in 'Nose' mode with one ADV at: 48 09.166', -122 41.174' Units ----- - Velocity data (_u, urot, uacc) is in m/s. - Acceleration (Accel) data is in m/s^2. - Angular rate (AngRt) data is in rad/s. - The components of all vectors are in 'ENU' orientation.

A heat budget for the Stratus mooring in the southeast Pacific

NASA Astrophysics Data System (ADS)

Holte, J.; Straneo, F.; Weller, R. A.; Farrar, J. T.

2012-12-01

The surface layer of the southeast Pacific Ocean (SEP) requires an input of fresh, cold water to balance evaporation and heat gain from incoming solar radiation. Numerous processes contribute to closing the SEP's upper-ocean heat budget, including gyre circulation, Ekman transport and pumping, vertical mixing, and horizontal eddy heat flux divergence. However, there is little consensus on which processes are most important, as many modeling and observational studies have reported conflicting results. To examine how the SEP maintains relatively cool surface temperatures despite such strong surface forcing, we calculate a heat budget for the upper 250 m of the Stratus mooring. The Stratus mooring, deployed at 85(^o)W 20(^o)S since 2000, is in the center of the stratus cloud region. The surface buoy measures meteorological conditions and air-sea fluxes; the mooring line is heavily instrumented, measuring temperature, salinity, and velocity at approximately 15 to 20 depth levels. Our heat budget covers 2004 - 2010. The net air-sea heat flux over this period is 32 W m(^{-2}), approximately 2/3 of the flux over earlier periods. We use Argo profiles, relatively abundant in the region since 2004, to calculate horizontal temperature gradients. These gradients, coupled with the mooring velocity record, are used to estimate the advective heat flux. We find that the cool advective heat flux largely compensates the air-sea heat flux at the mooring; in our calculation this term includes the mean gyre circulation, horizontal Ekman transport, and some contribution from eddies. The passage of numerous eddies is evident in the mooring velocity record, but with the available data we cannot separate the eddy heat flux divergence from the mean heat advection. Vertical mixing and Ekman pumping across the base of the layer are both small.

Time series pCO2 at a coastal mooring: Internal consistency, seasonal cycles, and interannual variability

Marine carbonate system monitoring programs often consist of multiple observational methods that include underway cruise data, moored autonomous time series, and discrete water bottle samples. Monitored parameters include all, or some of the following: partial pressure of CO2 of the water (pCO2w) and air, dissolved inorganic carbon (DIC), total alkalinity (TA), and pH. Any combination of at least two of the aforementioned parameters can be used to calculate the others. In this study at the Gray's Reef (GR) mooring in the South Atlantic Bight (SAB) we: examine the internal consistency of pCO2w from underway cruise, moored autonomous time series, and calculated from bottle samples (DIC-TA pairing); describe the seasonal to interannual pCO2w time series variability and air-sea flux (FCO2), as well as describe the potential sources of pCO2w variability; and determine the source/sink for atmospheric pCO2. Over the 8.5 years of GR mooring time series, mooring-underway and mooring-bottle calculated-pCO2w strongly correlate with r-values > 0.90. pCO2w and FCO2 time series follow seasonal thermal patterns; however, seasonal non-thermal processes, such as terrestrial export, net biological production, and air-sea exchange also influence variability. The linear slope of time series pCO2w increases by 5.2 ± 1.4 μatm y-1 with FCO2 increasing 51-70 mmol m-2 y-1. The net FCO2 sign can switch interannually with the magnitude varying greatly. Non-thermal pCO2w is also increasing over the time series, likely indicating that terrestrial export and net biological processes drive the long term pCO2w increase.

The Death of Two Eddies, Against the Shelf

2007-05-01

A set of five moorings deployed in front of the coast of Tamaulipas, western Gulf of Mexico, provided fourteen months (from August 2004 to November 2005) of surface to bottom observations of currents and temperature that document the processes associated with the collision and dissipation of two warm mesoscale eddies with the continental slope. Two Loop Current eddies (Titanic and Ulysses) were identified reaching the study area during the observation period. On September 2004, the two southernmost 2000-m moorings show that temperature and salinity increases throughout the entire water column, related to eddy Titanic; similarily; on April 2005, eddy Ulysses caused a strong increase of temperature in the 3500-m mooring. The velocity field suggests three different régimes: a coastal region, the continental slope currents, and the abyssal circulation. Over the slope, three different layers can be identified: a surface layer (above 500 m depth), influenced by eddies and transients, a deep layer (under de 1900 m) with a persistent southerly current and a transition layer (from 500 to 1900 m) that separates them. The variance ellipses at ~ 700 m at the 3500-m mooring have no a predominant orientation of the mayor axis. At the northernmost 2000-m mooring, the axis of maximum variation is oriented with the bathymetry, but at the southernmost 2000-m mooring it is perpendicular to the coast. The spectral characteristics of the measurements are also discussed.

Prototype monitoring techniques play an important role in the safety guarantee of mooring systems in marine engineering. In general, the complexities of harsh ocean environmental conditions bring difficulties to the traditional monitoring methods of application, implementation and maintenance. Large amounts of existing mooring systems still lack valid monitoring strategies. In this paper, an underwater monitoring method which may be used to achieve the mechanical responses of a multi-point catenary mooring system, is present. A novel self-contained assembled water depth-inclination (D-I) sensor is designed and manufactured. Several advanced technologies, such as standalone, low power consumption and synchronism, are considered to satisfy the long-term implementation requirements with low cost during the design process. The design scheme of the water resistance barrel and installation clamp, which satisfies the diver installation, are also provided in the paper. An on-site test has previously been carried out on a production semisubmersible platform in the South China Sea. The prototype data analyses, including the D-I value in the time domain (including the data recorded during the mooring retraction and release process) and spectral characteristics, are presented to reveal the accuracy, feasibility and stability of the sensor in terms of fitting for the prototype monitoring of catenary mooring systems, especially for in-service aging platforms.

Impact analysis of air gap motion with respect to parameters of mooring system for floating platform

NASA Astrophysics Data System (ADS)

Shen, Zhong-xiang; Huo, Fa-li; Nie, Yan; Liu, Yin-dong

2017-04-01

In this paper, the impact analysis of air gap concerning the parameters of mooring system for the semi-submersible platform is conducted. It is challenging to simulate the wave, current and wind loads of a platform based on a model test simultaneously. Furthermore, the dynamic equivalence between the truncated and full-depth mooring system is still a tuff work. However, the wind and current loads can be tested accurately in wind tunnel model. Furthermore, the wave can be simulated accurately in wave tank test. The full-scale mooring system and the all environment loads can be simulated accurately by using the numerical model based on the model tests simultaneously. In this paper, the air gap response of a floating platform is calculated based on the results of tunnel test and wave tank. Meanwhile, full-scale mooring system, the wind, wave and current load can be considered simultaneously. In addition, a numerical model of the platform is tuned and validated by ANSYS AQWA according to the model test results. With the support of the tuned numerical model, seventeen simulation cases about the presented platform are considered to study the wave, wind, and current loads simultaneously. Then, the impact analysis studies of air gap motion regarding the length, elasticity, and type of the mooring line are performed in the time domain under the beam wave, head wave, and oblique wave conditions.

Nanotubes May Break Through "Chip Wall"

NASA Technical Reports Server (NTRS)

Laufenberg, Larry

2003-01-01

In 1965, just four years after the first planar integrated circuit (IC) was discovered, Cordon Moore observed that the number of transistors per integrated circuit had grown exponentially. He predicted that this would continue, and the media soon began to call his prophesy "Moore's Law" For nearly forty years, Moore's Law has been validated by the technological progress achieved in the semiconductor industry. Now, however, industry experts are warning of a "Red Brick Wall" that may soon block the continued scaling predicted by by Moore's Law. The "red bricks" in the wall are those areas of technical challenge for which no known manufacturable solution exists. One such "brick" is the challenge of finding a new material and processing technology to replace the metals used today to interconnect transistors on a chip.

NASA Technical Reports Server (NTRS)

Walker, H., Jr.

1975-01-01

The problems of mooring and ground handling rigid airships are discussed. A brief history of Mooring and Ground Handling Rigid Airships from July 2, 1900 through September 1, 1939 is included. Also a brief history of ground handling developments with large U. S. Navy nonrigid airships between September 1, 1939 and August 31, 1962 is included wherein developed equipment and techniques appear applicable to future large rigid airships. Finally recommendations are made pertaining to equipment and procedures which appear desirable and feasible for future rigid airship programs.

Measuring Turbulence from Moored Acoustic Doppler Velocimeters. A Manual to Quantifying Inflow at Tidal Energy Sites

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kilcher, Levi; Thomson, Jim; Talbert, Joe

This work details a methodology for measuring hub height inflow turbulence using moored acoustic Doppler velocimiters (ADVs). This approach is motivated by the shortcomings of alternatives. For example, remote velocity measurements (i.e., from acoustic Doppler profilers) lack sufficient precision for device simulation, and rigid tower-mounted measurements are very expensive and technically challenging in the tidal environment. Moorings offer a low-cost, site-adaptable and robust deployment platform, and ADVs provide the necessary precision to accurately quantify turbulence.

To examine short-term and midterm outcomes after the David and Bentall procedures in patients with an acute type A aortic dissection. Between 2001 and 2017, patients (n = 135) with acute type A aortic dissection underwent an aortic root replacement with either the David (n = 40) or Bentall (n = 95) procedure. Perioperative outcome, reoperation rate, aortic valve function, and long-term survival were evaluated. The median age of the entire cohort was 56 years. Rates of malperfusion (21%), shock (16%), history of renal failure (4%), and extent of surgery were similar between David and Bentall groups. However, the David group was significantly younger (45 versus 61 years) with less hypertension (45% versus 66%), coronary artery disease (0% versus 17%), valvulopathy (5% versus 19%), and prior cardiac surgery (5% versus 21%). Overall operative mortality was 9.6% (David 3% and Bentall 13%). Composite outcome comprising myocardial infarction, stroke, new-onset renal failure, and operative mortality was 18% in the entire cohort (David 5% and Bentall 23%). In the David group, the freedom of moderate aortic insufficiency was 95% at 10 years. The rate of reoperation for pathology of the proximal aorta or aortic valve was 0% and 2% for the David and Bentall groups, respectively. Ten-year Kaplan-Meier survival was 66% (95% confidence interval: 51% to 77%) for the entire cohort, with 98% (95% confidence interval: 84% to 99%) survival in the David group and 57% (95% confidence interval: 42% to 70%) survival in the Bentall group. Both the David and Bentall procedures are appropriate surgical approaches for aortic root replacement in select patients with an acute type A aortic dissection.

Use of multi-disciplinary mooring data to extend intermittent OA observations from ship surveys

NASA Astrophysics Data System (ADS)

Send, U.; Ohman, M. D.; Martz, T. R.; Dickson, A. G.; Feely, R. A.; Demer, D.; Washburn, L.

2012-12-01

Ship surveys along the US West Coast have provided valuable insight into the conditions and changes in the water column that affect the ocean acidification state. Examples are the decades of CalCOFI sampling off southern California, and the West Coast ship survey published in Feely et al 2008. What is lacking in these observations is a description of the temporal variability of the conditions observed, and of the processes at work that lead to observed conditions or changes. Multi-disciplinary moorings are ideally suited for adding this dimension to the available observations which is critical for an understanding of the OA mechanisms. One example is the occurrence of corrosive water near the seafloor on the continental shelf, which was found in the Feely et al survey. Time series data from a mooring off Del Mar, California, with oxygen and pH sensors near the bottom in 100m depth show the frequency and intensity of corrosive and hypoxic conditions there, and how they relate to physical processes (cross-shelf and along-shelf flow), biological conditions, and climate processes (here La Nina). In the upwelling and open-ocean regimes off Pt. Conception two moorings (CCE1, CCE2) have been collecting data since early 2009 and 2010, respectively, co-located with CalCOFI stations and CCE LTER cardinal sites for ship observations. A glider also routinely passes by these moorings (along CalCOFI line 80). The moorings carry physical, oxygen, pH, pCO2, nutrient, and ecosystem sensors (chlorophyll fluorescence, water column irradiance absorption, acoustic backscatter) and telemeter most data in real-time. The mooring time series show the variability of OA parameters on daily, weekly, seasonal, and interannual time scales, and in the context of the spatial and historical sampling from ships. The multi-disciplinary sensor suite allows to study the forcing of the OA variability on those various time scales, and the impact on the ecosystem. Combined with the spatial information from ships, and with the physical and biological variables observed at the mooring, we can also start to estimate individual terms in a carbon budget. Examples for these applications will be given in the presentation.

2013-08-01

The 11th Anglo-French Physical Acoustics Conference (AFPAC) was held in Brighton, UK on 18-20 January 2012. This event, which is an annual collaboration between the Physical Acoustics Group (PAG) of the Institute of Physics and the Groupe d'Acoustique Physique, Sous-marine et UltraSonore (GAPSUS) of the Société Française d'Acoustique, successfully achieved its main aim of being a small, friendly meeting of high scientific quality, welcoming younger researchers and PhD students and covering a broad range of subjects in Acoustics. The participants heard 44 excellent presentations covering an exciting and diverse range of subjects, from audio acoustics to guided waves in composites and from phononic crystals to ultrasound surgery. As is the custom at these meetings, four prominent invited speakers set the pace for the event; these were Keith Attenborough (The Open University, UK), Claire Prada (Institut Langevin, France), David Moore (University of Nottingham, UK) and Philippe Roux (IS Terre, France). The submission of manuscripts for publication in the proceedings was, as in previous years, on a voluntary basis and in these proceedings we present 11 peer reviewed papers. Due to some unforeseen problems there has been a longer than planned delay in preparing these proceedings, for which the Editors sincerely apologise to the authors and the community.

'Nothing is so soon forgot as pain': Reading Agony in Adam Smith's The Theory of Moral Sentiments.

PubMed

Franson, Craig

2014-01-01

Giving a rigorous philosophical explanation to the imagination's role in sympathy, Adam Smith's The Theory of Moral Sentiments became a central text in Romantic aesthetics. It not only justified the age's vogue for making suffering an object of artistic pleasure, it treated suffering's affectivity as the very foundation of society. Depicting agony as a spectacle to be read by others, Smith transformed morality into rhetoric, making human subjects into readers of a sentimentalised, textual world. Yet Smith's work restricted the bonds of sympathy, too, following established distinctions between mind and body that helped him to exclude physical pain from sympathetic response. This essay looks to Smith's context in the overlapping philosophical and medical discourses of the Scottish Enlightenment, exploring his moral theory's resonance with the nerve theories of Robert Whytt and William Cullen, then the leading figures in Scotland's rising medical community. Deepening our understanding of Smith's probable sources, it reframes Smith's intellectual and ideological legacy, foregrounding some of the ambivalent cultural and political implications of Smith's troubling censure of physical pain.

The education and medical practice of Dr. James McCune Smith (1813-1865), first black American to hold a medical degree.

PubMed Central

Morgan, Thomas M.

2003-01-01

James McCune Smith (1813-1865)--first black American to obtain a medical degree, prominent abolitionist and suffragist, compassionate physician, prolific writer, and public intellectual--has been relatively neglected by historians of medicine. No biography of Smith exists to this day, though he has been the subject of several essays. Born, in his own words, "the son of a self-emancipated bond-woman," and denied admission to colleges in the United States, his native land, Smith earned medical, master's, and baccalaureate degrees at Glasgow University in Scotland. On his return to New York City in 1837, Smith became the first black physician to publish articles in US medical journals. Smith was broadly involved in the anti-slavery and suffrage movements, contributing to and editing abolitionist newspapers and serving as an officer of many organizations for the improvement of social conditions in the black community. In his scientific writings Smith debunked the racial theories in Thomas Jefferson's Notes on the State of Virginia, refuted phrenology and homeopathy, and responded with a forceful statistical critique to the racially biased US Census of 1840. Frederick Douglass, Gerrit Smith, and John Brown personally collaborated with James McCune Smith in the fight for black freedom. As the learned physician-scholar of the abolition movement, Smith was instrumental in making the overthrow of slavery credible and successful. Images Figure 1 PMID:12911258

Model-based assessment of a Northwestern Tropical Pacific moored array to monitor intraseasonal variability

NASA Astrophysics Data System (ADS)

Liu, Danian; Zhu, Jiang; Shu, Yeqiang; Wang, Dongxiao; Wang, Weiqiang; Cai, Shuqun

2018-06-01

The Northwestern Tropical Pacific Ocean (NWTPO) moorings observing system, including 15 moorings, was established in 2013 to provide velocity profile data. Observing system simulation experiments (OSSEs) were carried out to assess the ability of the observation system to monitor intraseasonal variability in a pilot study, where ideal "mooring-observed" velocity was assimilated using Ensemble Optimal Interpolation (EnOI) based on the Regional Oceanic Modeling System (ROMS). Because errors between the control and "nature" runs have a mesoscale structure, a random ensemble derived from 20-90-day bandpass-filtered nine-year model outputs is proved to be more appropriate for the NWTPO mooring array assimilation than a random ensemble derived from a 30-day running mean. The simulation of the intraseasonal currents in the North Equatorial Current (NEC), North Equatorial Countercurrent (NECC), and Equatorial Undercurrent (EUC) areas can be improved by assimilating velocity profiles using a 20-90-day bandpass-filtered ensemble. The root mean square errors (RMSEs) of the intraseasonal zonal (U) and meridional velocity (V) above 500 m depth within the study area (between 0°N-18°N and 122°E-147°E) were reduced by 15.4% and 16.9%, respectively. Improvements in the downstream area of the NEC moorings transect were optimum where the RMSEs of the intraseasonal velocities above 500 m were reduced by more than 30%. Assimilating velocity profiles can have a positive impact on the simulation and forecast of thermohaline structure and sea level anomalies in the ocean.

Maintaining Moore's law: enabling cost-friendly dimensional scaling

NASA Astrophysics Data System (ADS)

Mallik, Arindam; Ryckaert, Julien; Mercha, Abdelkarim; Verkest, Diederik; Ronse, Kurt; Thean, Aaron

2015-03-01

Moore's Law (Moore's Observation) has been driving the progress in semiconductor technology for the past 50 years. The semiconductor industry is at a juncture where significant increase in manufacturing cost is foreseen to sustain the past trend of dimensional scaling. At N10 and N7 technology nodes, the industry is struggling to find a cost-friendly solution. At a device level, technologists have come up with novel devices (finFET, Gate-All-Around), material innovations (SiGe, Ge) to boost performance and reduce power consumption. On the other hand, from the patterning side, the relative slow ramp-up of alternative lithography technologies like EUVL and DSA pushes the industry to adopt a severely multi-patterning-based solution. Both of these technological transformations have a big impact on die yield and eventually die cost. This paper is aimed to analyze the impact on manufacturing cost to keep the Moore's law alive. We have proposed and analyzed various patterning schemes that can enable cost-friendly scaling. We evaluated the impact of EUVL introduction on tackling the high cost of manufacturing. The primary objective of this paper is to maintain Moore's scaling from a patterning perspective and analyzing EUV lithography introduction at a die level.

Summary: The database for annotation, visualization and integrated discovery (DAVID), which can be freely accessed at http://david.abcc.ncifcrf.gov/, is a web-based online bioinformatics resource that aims to provide tools for the functional interpretation of large lists of genes/proteins. It has been used by researchers from more than 5000 institutes worldwide, with a daily submission rate of ∼1200 gene lists from ∼400 unique researchers, and has been cited by more than 6000 scientific publications. However, the current web interface does not support programmatic access to DAVID, and the uniform resource locator (URL)-based application programming interface (API) has a limit on URL size and is stateless in nature as it uses URL request and response messages to communicate with the server, without keeping any state-related details.

The database for annotation, visualization and integrated discovery (DAVID), which can be freely accessed at http://david.abcc.ncifcrf.gov/, is a web-based online bioinformatics resource that aims to provide tools for the functional interpretation of large lists of genes/proteins. It has been used by researchers from more than 5000 institutes worldwide, with a daily submission rate of ∼1200 gene lists from ∼400 unique researchers, and has been cited by more than 6000 scientific publications. However, the current web interface does not support programmatic access to DAVID, and the uniform resource locator (URL)-based application programming interface (API) has a limit on URL size and is stateless in nature as it uses URL request and response messages to communicate with the server, without keeping any state-related details.

A ferromagnetic material involving nickel-iron particles embedded in a polyethylene matrix is synthesized and electrically characterized between 1 and 12 GHz. These measurements show the combination of electric and magnetic activity along with significant loss terms. We take benefit of these properties for the design of broadband electromagnetic absorbers. To this aim, we use a fractal structuring based on Moore curves. The advantage of etching patterns over metallic ones is clearly evidenced, and several pattern absorbers identified by their Moore's order iteration are designed and analyzed under oblique incidence.

Gary Jordan (Host): Houston, we have a podcast. Welcome to the official podcast of the NASA Johnson Space Center, episode 45, "Digital Space". I'm Gary Jordan, and I'll be your host today. So, in this podcast, we bring in the experts, NASA scientists, engineers, astronauts, sometimes our leaders. We bring them right here on the show to tell you about all the cool stuff that's going on right here at NASA. So, today, we're talking about data and information in space and here at the Johnson Space Center with Annette Moore. She's the Director of our Information Resources Director and the Chief Information Officer here in Houston. And, we had a great discussion about the tech we use for human spaceflight operations, including space station imagery and how it's changed over time. And then, how the Johnson Space Center is handling the multiple petabytes of data. It's actually unbelievable how much data we have. The multiple petabytes of data and information that we use all the time in our everyday lives. So, with no further delay, let's go light speed and jump right ahead to our talk with Ms. Annette Moore. Enjoy. [ Music ] Annette Moore: T minus five seconds and counting. Mark. [ Inaudible Comment ] Annette Moore: Houston, we have a podcast. [ Music ] Host: All right. Annette, thank you so much for coming on the podcast today to talk about this digital space. Annette Moore: Well, I'm pretty excited about this, and I'm glad I had the opportunity to sit down and talk with you. Host: Absolutely. And, it's, I'm particularly excited about it because we're talking about data, that not only we deal with every day, but was we were, we were just chatting just a little bit before this. There's a whole history of data, and we have, you know, we have records of all of the history of our flights that we have to maintain to a certain level, and we are required to maintain in a way that is going to, I guess, we're going to pass forth and make sure that we can retain for years to come. Annette Moore: Absolutely. Yeah. Host: There's a lot of stuff here. Annette Moore: Yeah. Host: And, we're talking about data from, from some of the Legacy programs, too, right? Annette Moore: You bet. Host: We're talking about Apollo, Gemini. Annette Moore: Apollo, Gemini. You bet. Yes, yes. Host: Wow. So, why don't we start, start with that? Why don't we start with some of the data that we're, that we're dealing with? Kind of continuing from the conversation that we were talking about earlier. What is some of the historical data that we have, and how are we keeping it? Annette Moore: So, we have data that dates all the way back to the Apollo program, and that data is kept in various forms of media. So, originally, you might imagine when we first started getting that data, that data was on paper. It was on tape. And, I mean the old fashioned, reel-to-reel tape. And, as we've moved more into the digital age, we're converting that to digital. Of course, NARA has, which is the National Archives, they have certain requirements for how they will receive data, how long data has to be retained at the federal agency. So, we have retention schedules. And so, we follow those retention schedule for when a program ends and how long we actually keep that data at the center. And then, it transfers over to NARA. But, again, as I said, NARA has some stringent requirements on how they will or will not except that data. So, we are certainly abiding by those requirements from NARA, the retention schedule and the media in which we store that data and send that data to NARA. But, it is a plethora of history, a plethora of data and information, and it tells an incredible story of NASA and the space program. Annette Moore: Yeah, a lot of the things that you see on documentaries, you know. And, I'm imagining is you have to, you have to sort of cradle the data, take care of it, raise it to be. Annette Moore: Absolutely. Host: I guess what NARA is requiring it to be. Annette Moore: Yeah, absolutely. Host: And then, send it off into the world to. Annette Moore: Yeah, yeah. Host: I guess, I guess explore and be used. Annette Moore: Yeah. Well, we value that data very much. We have some of that data in the form of oral history where folks have actually interviewed folks from the old programs, and they have a wealth of information and data that they share. And, that data is not just used for the purposes of memorable content, but it's actually used to inform some of our programs moving forward. Host: Yeah. And, talking about data, just, the landscape where we are now, we're dealing with just insane amount of data. Yeah, and you're talking multiple petabytes. Annette Moore: Yeah. Host: You were talking before. Annette Moore: Yeah. Host: Just billions. It's. Annette Moore: Billions and billions of data. Yeah. Host: It's incredible. So, let's, I guess, start from the beginning and see how we got to this point. How did we get so much data? What were we dealing with, what were some of the legacy technology and information that we were dealing with, and the start of the space program? Annette Moore: So, you know, it's really interesting because I'm going to kind of date myself here. So, I started back in the shuttle day, and I can remember working over in building 30. And, pretty much like, and I wasn't, I wasn't this far dated back. But, when you go to the bank, and you have the pneumatic tubes that they send your money through, through the teller. You know, that actually started as far back as that, you know, in terms of how you transmitted the data. Now, we transmit the data over network lines. We transmit the data via station coming downlinked to the Mission Control. We transmit the data in various forms. We receive the data in various forms. We analyze the data, and then we store the data in various forms. And so, that dates all the way back to the beginning of the shuttle program, all the way back to the beginning of the Apollo era, all the way back to when we were looking at data and deciphering that data and deciding how we needed to store that data, what we needed with that data. And, what data was important and what data wasn't. I think back then, everything was data. We kept everything. We stored everything. When programs expire, they're supposed to actually bring those, that data current and put that data in a format and a form that can go to NARA. We have boxes and boxes of data over, and our archivist is storing that data when a program ends. And so, I've been across several of the centers, and I'm just astounded by the data that they have that they're collecting and that they're storing. So, that's something that we're known for. That's part of our legacy. And, I think it's a great legacy that we have. Host: Yeah. Annette Moore: Yeah. Host: That's, well, the history is phenomenal. Annette Moore: The history is, it's phenomenal. It is. Yeah. Host: So, when you're talking about different kinds of data, going back to those tube days, the pneumatic tubes. You're not talking about information that's stored electronically. You're talking about. Annette Moore: That's right. Host: Physical copies of data that have to be. Annette Moore: That's absolutely right. Host: Physically filed away. Annette Moore: That's absolutely right. I'll tell you, that's true even in our medical profession. Think about when you used to go to that, again, I'm going to age myself. When you, you know, I'd go to the dentist's office, and they'd role out the file cabinet, you know. They'd have the tall file cabinets, and they literally would have a rotary. And, they would roll out, and that's how they stored data. That data now, because there are government requirements now to go to an electronic format for that data. And so, we've moved into that age. We weren't always there. We've moved into that age but think about the cycles of individuals that it takes, the cycles of time, the cycles of transferring across the age of technology to convert that data into a format that is now usable in this current age. So, we've gone through quite a transition with the data. Host: Now, there was, there was a lot of data in our history, too, and, you know, file cabinets, right? You're rolling stuff out. But, not only that, even the technology that was digital. Annette Moore: That's right. Host: Took up a lot of space. Annette Moore: Took up a lot of space. It did. You know, I can remember in my early days of program, and we had the big, round discs that had all of the data for your program files that you would store. It's quite different, and now, you have, what, a little disc that you pop in. You have a little thumb drive that you pop in. Host: Yeah. Annette Moore: But, that actually has tons of data on it as well. Host: But, that's just because of how technology has progressed. Now. Annette Moore: Absolutely. Host: What used to take an entire room, maybe even a floor, we can go back to store the amount of data that you can now store on a thumb drive. Annette Moore: Yes, absolutely. Absolutely. You bet. Host: Now, I'm thinking about Mission Control. This is always one of my, one of my just, I'm blown away by this statistic is the comparison of the data that Mission Control was dealing with versus what a current smartphone can deal with. Annette Moore: Yeah. [laughs] Host: Is it true a smartphone can actually compute more? Annette Moore: That's absolutely true. Back in the Apollo era, that is absolutely true. You bet. Yeah. Host: Wow. Because you were dealing with kilobytes of data, right? Annette Moore: You bet. You bet. Host: Unbelievable. Annette Moore: Yeah, that is. Host: How did that, how did, how can you fly a rocket, how can you communicate a deal with space systems with such little data? It, I mean, why can I not fly a rocket with my phone right now? [ Laughter ] Annette Moore: Well, technology has advanced over time. What we have done with that technology has also changed over time. And, I think our goals and our objectives and where we were trying to get, that's changed over time. And so, with that, all of the things that are associated with it, not just the technology, but the smarts that it takes to do that. That's changed over time. How we test has changed. How we prepare for flight readiness has changed. And so, all of that with that, that advancement of technology has been very necessary. I always tell people NASA hires smart people, and they absolutely do. I look back in the John Glenn day, and I look at what those guys were doing and what they were computing in their heads, what they were computing with pen and paper and how we do it very differently now. But, it's still the same, math is math, yeah. Host: That's true. Yeah, we just have a lot more, I guess, computer help. Annette Moore: We have a lot more computer help. We absolutely do. Host: Yeah. Annette Moore: Yeah. Host: So, the processes of just working in Mission Control, working here and dealing with data. Now, you're talking about converting from a time of you're doing math with hand. Annette Moore: With hand. Host: And, a pen, on your desk, and just dealing with all of the computer. How have you seen the workplace shift over time or know about the shift over time between just dealing with more and more data? Annette Moore: So, it's shift everywhere from the physical construct of the work environment to what's necessary, the tools that are necessary for you to do your job, to the whole thought process behind how you do your job. That has shift. If you look back into even how we were simulated in our work environment, how we work closely together in big rooms where information was being shared. You share information. I share information across the continent to other folks. I share information across to other centers that are on opposite ends of the spectrum from me. So, you share information, and you look at how you do that and how we had to do it once. And, it really composites setting with everyone in the same place at the same time. But, now, technology affords us an allows us to share that information across the globe. I mean, that's phenomenal to me. You know, I think that's how we learn, and that's what we've learned so well. Host: It is, I consider it a fortunate thing that we can access so much information so readily. But, at the same time, sometimes I just want to shut off my phone. Annette Moore: I know. Host: And, just ignore [inaudible]. Annette Moore: I know, yeah. Host: We are very connected. Annette Moore: Yes. Host: Almost too connected. Annette Moore: Well, you know, that, so that's interesting that you say that because the conundrum associated with that is you're concerned then, what about the security of that data that I'm sharing. Host: Yeah. Annette Moore: That becomes a huge concern, and certainly, in my environment, in the CIO environment, in the IT world, you hear it every day. You hear about breeches and compromises. So, we used to be concerned about the device and making sure that the device is secure. What you're really concerned about, and it's a conversation we're having right now, is the data that's on that device. You want to make sure that that data is secure. So, that's huge. Host: Yeah. Because the kinds of data we [inaudible], and we should probably clarify this, is there's so much data, but it's pretty diverse, too. You know. Annette Moore: It is. Host: We're dealing with just regular math equations, like we were saying before, but then, also, there's sensitive aspect to it. Annette Moore: Yeah. You bet you. Host: There's stuff that is preliminary that can be, there's certain sensitivities that you have to protect. Annette Moore: Absolutely. You have scientific data. You have engineering data. You have health data. You have PII data. Very sensitive data at very different levels of that data. You have data that's associated with flight equipment and flight hardware. You have software, and so, yes, it has to be protected, and it has to be protected at different levels. Host: Now, we as a federal agency, I'm sure, have much more restrictions on these kinds of things. Annette Moore: Absolutely. Host: So, what's the environment on what we do to protect this data? Annette Moore: Absolutely. So, we have requirements that all federal agencies are accountable to through OMB, through NIS. Cybersecurity related requirements that require us to secure the data, to protect the data. Now, it's interesting because, as a federal agency, one of the things that NASA has to do is to share that data. That is publicly available data, and so we share that data. We have a Space Act agreement that talks about the sharing of that data with the public, but we also have a requirement and a responsibility to protect that data. And so, with that comes a lot of requirements. Currently, I will tell you at the agency level, through the Office of the CIO, Department of Homeland Security, and it's not just for NASA. It's for all federal agencies. They're providing tools and capabilities that enable us to store that data, to secure that data, and to ensure the security and the protection of that data. Host: And, what's, I guess, unique about this, and you kind of eluded to this before was you're protecting the data that you have, because it's your data, right? But, in order to operate, because we are, we're not just NASA. We are partnered with international. Annette Moore: Absolutely. Host: You know, we're partnered with nations across the globe. Annette Moore: Yes. Host: And, you're right, we have to share this information. So, how do you ensure that we can share what we need to share but that we're going to stay protected, and we're not going to have some sort of incident where people are going to be exposed? Annette Moore: So, they have the same requirements levied on them, and I can assure you they have the same concerns that we have ensure that they share the right information, that they share the right data, and that they protect the data that they share. And so, through our IT security program here at the Johnson Space Center, we're accountable to the OCI, or the Office of the CIO at the agency level. We're accountable to external entities such as Department of Homeland Security, Office of Management and Budget. There are requirements that are levied on us for our cybersecurity program. And, at the center here, through my office, we have a cybersecurity office that's actually our IT security office. With each organization here at the Johnson Space Center, you have representatives within those directorates that are responsible for the security of the systems and the data within their organization. And so, that accountability goes across the board. So, cybersecurity is a responsibility of everyone. That's everyone's responsibility. In your work environment as well as in your home environment. Host: You're right, because ultimately, it's your data, and you might not be a person who's a technical person to deal with it, but ultimately, it's your data that you're responsible for. So, you have to make sure that it's protects, and you're constantly thinking about, am I protected. Annette Moore: Yes. Host: Yeah. Annette Moore: Yes. Host: So, you're talking about requirements, and you're talking about, from the federal level, these restrictions being imposed. What are some of the things that we are required to do? What are some of the, give me an example of a requirement. Annette Moore: Right. Host: That may be, maybe is more difficult to do business. But, is essentially to make sure that we are protected. Annette Moore: So, every system that we have here at the Johnson Space Center has to be under security plan. And, it has to have the authority to operate. So, as the Center's CIO and as the authorizing official for some of those systems, I have to say that that system has the authority to operate. Well, that system has to meet certain requirements. It has to make sure that it has patching. There is scanning and vulnerability testing that's done on those systems, and if any of that is not successful, there has to be a plan of action and milestones and a mitigation plan and strategy to make sure that those systems are healthy. Or, those systems should not be connected to our network. That's a requirement for every system on this Center. And so, when I sign my name to a system as authorizing official, I'm saying that that system is healthy, it does not put the Center at risk, it does not put us in a situation of possible vulnerability occurring with that system. And, I'm signing off on that, as are the other authorizing officials for systems here at the Center. That's a requirement, not just for NASA, but for other federal agencies for their systems. The PIV implementation that we're doing right now, that's securing access to your devices, to your computer, and making sure that where you're going on the network, you have authority, and you have the right to access those systems and that data on those systems. Host: So, that's the, that's the badges that we carry around. Annette Moore: That's the badges. Host: That identify us, but then also say I am Gary, and I can access this computer. Annette Moore: Absolutely. You bet. Host: On the available access that's on this chip. Annette Moore: You bet. Host: Okay. Annette Moore: Yeah. Host: And so, basically, you're saying that all of these, all of these systems are carefully watched, and if some, and they are scanned. Annette Moore: Yes. Host: And, if something is revealed to say there is a vulnerability, there's a chance that something bad could happen, you make a plan of action to go fix it. Annette Moore: Absolutely. Host: Okay. Annette Moore: Absolutely. We don't want things connected to our network that could put us at risk. So, we have critical mission data. We have sensitive human health and performance data. We don't want anything on our systems, in our data, that could put us at risk or that could put our crew at risk or the vehicle at risk. Host: Do you see a lot of instances of folks trying to hack us, trying to, trying to get into our systems and, just you realize, because you understand probably the scope more than any of us. You know, we're sitting pretty. We're on our email. We're doing our thing, but you're saying maybe there's a side to this where we are being attacked. And, maybe we just don't know it, but our security is good enough where we don't know it. Annette Moore: Yeah. Yeah. I think you should always assume that your best posture is to be a posture where you're secured, and you're protected. I think everyone should always assume. I assume that at home with my home computer. You know, I don't click on links. I don't download things that are not credible. I assume that on my home system, I assume that on my work systems. We all should at all times. I mean, I'm not sure about you, but I've gotten a letter or two from LPM about my data being compromised because of a store that I've shopped at and my credit card number got out, as did other folks. I've been in that situation before. I just recently sent one of my siblings a text message. I said, "Hey, I know you were shopping here last month. I just saw on the new where they had a breech." I said, "You probably want to write them, and you probably want to contact your bank." I think we should always all assume that I'm going to be safe and I'm going to make sure that my systems and my data is secure. Host: Yeah. You have to be, it's kind of, you have to be constantly vigilant. Annette Moore: Yes, you do. Host: You have to be constantly aware. Annette Moore: Yes. Yes. Host: Which is kind of a burden, but also necessary. Annette Moore: It's necessary. Yeah, yeah. Host: Now, I was talking about, we were talking about requirements before, and there's obviously security requirements to make sure we're safe. But, going back, we were talking a little bit about NARA and requirements for storing data. What do we have to do to make sure that we are archiving all these great things that we're doing properly so that it could be stored properly? Like, mission videos, like when we do cool things in space and have video of it. I want to make sure that that's kept. Annette Moore: So, we have a records manager. We have each organization has someone within their directorate who is responsible for making sure that we're following the guidelines of NARA. That actually should start at the very beginning of a program, at the very beginning of a program, and it's the same way you do security. You don't do security at the end of the system. You do security at the very beginning, from cradle to grave. And, it's the same way with records retention. When you start kicking off a program, you should, then, start actually recording your records and keeping your records and keeping them according to the requirements for NARA. And so, when that program ends, you've got all your records according to how you're supposed to capture your records, record your records, save your records, file your records. You've got all of that in order. And, that's critically important. As I said, a lot of that data is used on newer programs from previous programs. I had a visit out to Wallace, actually to, I'm sorry, White Sands a couple of months ago. And, years ago, at the very beginning of my career, I worked on small ICPM missiles, and I worked at Peacekeeper and Minuteman. And, to my surprise, I walked in, and there was the missile head from Peacekeeper that I worked on years ago, early in my career. And, we're using information from that to help inform us as we move forward with our new programs such as Orion. And, I was just like, "Wow, that was at the beginning of my career. I can't believe I'm seeing this," you know. Host: Blast from the past. Annette Moore: But that shows the criticality and the importance of maintaining good records and keeping those records from the beginning of a program to the end of that program and making sure that that data and that information, then, can be passed on for future programs. Host: Yes, because it's learning. Annette Moore: It's learning. Absolutely. Host: It's learning. In order to make things better, you need to know how they were first. Annette Moore: Absolutely. Host: Yeah. Annette Moore: Yeah. Host: So, so, we have these requirements to document thing a certain way. Were these, have we captured everything successful, or are there things that we're just, we're just not going to get? Annette Moore: I think what we've done is we've learned along the way. I think we've learned and we've gotten smarter with how we have captured records, how we have retained those records, how we have stored those records. And, I think that program has improved over the years. I've seen it just in the span of time that I've been working in the office of the CIO. I've seen where we've gotten really smart. We've partnered with other organizations. We've partnered with other federal agencies. NARA is very helpful and very good at helping federal agencies [inaudible] because that is a legacy, not just of a federal agency, not just of a program. That's the legacy of our country. Host: Right. Annette Moore: Yeah. Host: Yeah. You know, they want to make sure that it's not lost. Annette Moore: They want to make sure. Yeah. Host: So, they will help us along the way to make sure. Annette Moore: They help us, yeah. Host: Okay. Annette Moore: Yeah. Host: So, so, where, yeah, make sure that we capture all this great history that we're doing. Annette Moore: Yeah. Yeah. Host: Now, I think one of the biggest challenges is it's got to be technology because what used to be maybe a little datapoints with kilobytes of information, now we're getting video. Now, we're going to HD video. Annette Moore: Yeah. Host: There's not only a different kind of data that we're dealing with, but it's larger. Annette Moore: It's larger. Host: And, we got to figure out where to put it because that's a lot of data. Annette Moore: Larger, very sophisticated. Host: Yeah. Annette Moore: Different ways to manipulate the data, different ways to manage the data and maintain the data. And so, we have to progress with the progression of the technology. We have to get smarter with the technology, and we have to really learn how to use it and leverage it to the best advantage that we can and to ensure that it provides capability that we need. Host: So, it sounds like one of the biggest challenges is going to be balance. Balance on the requirements that you have for certain technologies, but then also making sure that you're keeping up with the technology itself. Annette Moore: You bet. Absolutely. Host: So, maybe technology, and people talk about this all the time, is progressing so fast. Annette Moore: Yeah. Host: Not a lot of people can keep up with it. So, how do you write procedures and rules to make sure that we can keep up with it, at least to the best of our knowledge and capability? Annette Moore: So, one of the things that I think is hugely important is that we are staying out there ahead of the technology, or at least in sync with the technology. So, one of the things that we like to ensure that the folks on our team are doing, that they're exposed to this growth in technology, that they're partnering with other organizations outside of federal government, outside of NASA, because folks outside of federal government are, they're taking the risk that we sometimes don't take because we just don't have the opportunity to take that risk. Our schedules, our projects, our timelines, the fact that we're doing, dealing with humans in space, it maybe allows us to not take some of the risks that other folks take in terms of progressing technology. But, in partnering with those folks, benchmarking with those folks, we're learning where the technology is going. I was just at a CIO face to face last week, and we're talking about what are we going to look like three to five to ten years from now. We're not talking about what are we going to look like a year from now. We're talking about what is it going to look like three to five to ten years from now. We have to do that. Host: Yeah. Annette Moore: Yeah. Host: Now, the difficulty is you can, looking ahead, try to think three, five, ten, but then, there's so many technologies that maybe we don't even know are on the horizon. Annette Moore: We don't know. Yeah. Host: That you have to plan for. Annette Moore: Yeah. Host: That's got to be difficult. Annette Moore: Absolutely. Absolutely. Yeah. Host: I know there's just a lot of challenges with dealing with this data, and we were talking about, we're talking about HD video, and now I know recently, we were doing 4K downlinks. Where, now, we're dealing with 4K. Annette Moore: Yeah. Host: So, one of the biggest things I'm thinking of is storage. Do we store a lot of things here on the Center? Annette Moore: We do. We have a data center here, and it's interesting. I love that you just asked me that because we just entered a wonderful partnership that I'm very proud of with Station where we moved over to a new storage content platform for them for all of the imagery that we get, the still, the video. Everything that we get that's downlinked from Station. This is data that we're getting every day. So, just imagine, just the flood of data that's coming in every day. And, we actually entered a partnership with them just last year on a content platform for their storage, and we presented a business case to them. And, this was so exciting for us because it provided us an opportunity not look at where they are just right now. But, at the rate that we're getting data from Station, and that rate is not going to slow down. We wanted to provide a storage platform for them that would allow them to look years out and continue to build on that and not have to be concerned about I'm going to run out of storage space. And so, we sat with them, and we worked with them to understand what their requirements would be, not just for today, but where they saw themselves, five, ten, years from now and built this platform for them out in our data center. And, we're very proud of that. It was a great partnership that we had with them, and we're going to continue to build on that. Host: It was very exciting. Annette Moore: Yeah. Very exciting. Yeah. Host: Now, I think, you know, you're talking about planning, planning farther ahead, even. Annette Moore: Yes. Host: With these, with these servers. So, I'm sure you're thinking of this is going to meet our capabilities for storing now, and then, going back to the requirements of we have to keep our data for. Annette Moore: Yes. Host: A certain amount of time, and then, fit it for NARA requirements. Annette Moore: Exactly. Host: I'm sure that's part of the plan, too. Annette Moore: Yes. Yes. And, part of what we look at when we look at that, as well, particularly in the subject of storage, is we look at, so, when do we move or what do we move into the cloud environment. Because, that allows us more elasticity in terms of storage capability for our data. You know, there's that security element around that as well. Host: Yeah. Annette Moore: Who owns your data? Host: Right. Annette Moore: You know, what are the requirements for your data being in the cloud? What's the cost of being in the cloud? So, those are all of the things that you have to consider, and that's certainly part of the conversation when we look at what our options are for storage. And, not just storage, but how we can securely store our data and affordably store our data. Host: It's a big balance, right? Annette Moore: It is. Host: Secure but affordability. Because you can keep it here, but then you have to buy these servers. Now, you have to have this machinery, this hardware that's going to keep everything. That can get up the costs. It's yours, and you're secure because it's not, you know it's your data. So, you got that, but then, at the same time, technology is maybe going toward the cloud, and how do we fit things into the cloud but make it still ours? I can see where there's a lot of back and forth there. Annette Moore: I love where this conversation is going because we were just talking earlier about requirements that are imposed on us at a federal level. We're a federal agency. Host: Yeah. Annette Moore: And, one of the things that we had a requirement for, and not just us NASA, but federal agencies, was to reduce our footprint for our data center. Reduce our physical footprint, the number of data centers that we have. And so, that's when you look at technologies like going to cloud and how you can enable that. Host: Wow. So, okay. So, it's actually looking at requirements to limit what we have physically, and to. Annette Moore: Absolutely. Host: Actually opt into using cloud technology. Annette Moore: Yeah. Host: That's pretty significant. Annette Moore: That is. Host: But, now, you have a whole bunch of more challenges of security and ownership and. Annette Moore: Absolutely. Host: Stuff like that that you have to deal with down the road. Annette Moore: Absolutely. Yes. Host: Lot of challenges going on. Annette Moore: Lot of challenges, but you know, I will tell you, I really see those challenges as opportunities. And, that's what I tell my team. Those challenges are really opportunities for us to move forward, you know. I want to be in control of my destiny. Host: Yeah. Annette Moore: I don't want someone to be in control of that for me. I want to be in control of that. I want to be at the table when we're talking about where this agency is going to be three, five, ten years from now, what our future looks like. That's hugely exciting. Host: It is very exciting. Now, thinking towards the future and making sure we can, we can get there, I actually am going to redivert this to the past. And, we were talking about, you know, we have data centers that have this digital technology stored in these servers. So, we can, we can house our own data here, but we have different types of data. We have, we have tapes from the Apollo days and from, and from shuttle days that we need to convert. What's that process look like? How are we doing that? How are we taking this older technology and converting it? Annette Moore: I would love to take you on a tour out to what we call our farm, because. Host: Okay. Annette Moore: We literally have the reel-to-reel tapes that I can remember as a kid. You probably can't, but I can. [ Laughter ] You know, the reel-to-reel tapes, and we are actually converting that to digital format. And so, that's happening right here on site. That's happening at other centers because other centers have that same challenge. When you think back to that era where all you had were the reel-to-reel tapes. That's all you had. So, now, you've got to convert that because some of that tape also is going through what they call the vinegar syndrome where it's deteriorating. So, that's history. That's information. You'll never recapture that if you lose that. So, you want to convert those things to their appropriate format. And, of course, that's not something that NARA would accept. If you've got film that's going through the vinegar syndrome that would not be a good storage solution for NARA with all of the responsibilities that they have for maintaining the legacy for our nation. So, we are, we have moved to technology that is allowing us to convert it. Now, here's the challenge. As you said, plethora and plethora of data. Host: Oh, so much. Annette Moore: So, the time that it takes to do that conversion, trying to do that quick and where that data is still good, and you can get it converted to that new format. Host: You're right. Because you're talking about, I mean, like, shuttle missions, for example. Annette Moore: Exactly. Host: That lasted for weeks, and you just have a continuous stream of weeks of data. Annette Moore: Absolutely. Host: That you have to convert. Annette Moore: Absolutely. Host: But, it's, I like how you're saying that it's, not only is it a requirement that we have to have it digital in order to store it with NARA, now you're talking about just saving the film itself. Annette Moore: The film itself. Yeah. Host: The film itself is going to disappear if we don't do something. Annette Moore: Absolutely. Host: So, we have to do something to save that data. Annette Moore: Absolutely. Absolutely. You know, I'm so proud that the folks in my organization understand the importance of that, the importance of that, the history that that has a legacy that that has, and that they're committed to that. And, I, when I visit the other centers, I see that same commitment to that, you know. And, it's great. Host: It's a lot of hard work. Annette Moore: Yeah, it is. Host: Because it's very monotonous labor, right? You have to, all right. Put in another film reel. Here we go. I mean, there's a lot to it, but it's vital to save that stuff. Annette Moore: And, I got to tell you, I'm going to, you want you to hold me to this. I'm going to take you on a tour out to our farm where the guys are doing that. Host: All right. Annette Moore: They understand that when they pick up that reel of film, that's history that they have in their hand. Host: Yeah. Annette Moore: I can recall getting a call from the guys out there, and they had found a reel of film that showed the original construction of Johnson Space Center. And, they were so excited. They were, "You won't believe what we came across. You won't believe what we found." You know, I mean, they had, they take great pride in doing that, and that's so cool, I think. Host: To be, I mean, to be the first person to hold that. Annette Moore: Yeah, yeah. Host: Film reel in decades. Annette Moore: Yeah. Host: That's got to feel very special. Annette Moore: Yeah. Host: And, to say, "I'm going to save this!" Annette Moore: Yeah. Host: "I'm going to be the person that going to save this." Annette Moore: Exactly, exactly. Host: "For somebody else." It's on record, though, so I'm going to hold you to it. Annette Moore: Yeah, yeah. Host: The tour. [ Laughter ] Annette Moore: You bet. You bet. Host: So, this is probably a very important question to follow up on is we're saving all this data. It's history. We're putting into the archives. What, what are some of the ways that we can use that data? Why would we save all of it versus just, eh, this is important? We don't need it. We don't need to save it. It's just going to take up space. How do you decide what's important, what's not, and why to save it? Annette Moore: So, there are certain requirements for what you have to save. NARA has some requirements on that in terms of the kinds of things you save. I'll give you an example. Even senior executives, things like their email records, that is considered a record. Think about that. Think about what's documented with our Presidents. You know, speeches that they've had, decisions that they've made, you know, law that has been enacted. There is a reason we say that it tells a story. It is our legacy. It says who we are. It informs us. It's in our textbooks. It informs us. It helps us in terms of building our future. Those are things that are vitally important to us as individuals, vitally important to us as a nation, vitally important to us on this globe. Host: Yes, yeah. So, it's, you recognize the importance. I think one of the things on my mind is immediately going to is whenever we've had, whenever we've had some of the recent accidents, right? Annette Moore: Absolutely. Host: So, like, if you're talking about the Columbia accident. Annette Moore: Absolutely. Host: Now, you have this data where you can go back. Annette Moore: Absolutely. Host: Look at every excruciating detail. Annette Moore: Absolutely. Host: Because we have it. Because you saved it. Annette Moore: Yes. Host: And, it's crucial to find out what went wrong, what can we do to fix it, what can we do to prevent it from happening in the future. Annette Moore: You can even think in everyday terms of how we study weather data. You know, so, I was impacted by Hurricane Harvey. Host: Yeah. Annette Moore: And, when I think about the studies that go behind weather and weather patterns and things that they watch for the weather, I'm very grateful for that because that alerts us, it alarms us in a way that keeps us safe. But, that's important for our survival. This data is as well. Host: Yeah. Annette Moore: The survival of our crew. Host: Exactly. It's like the more you know, the more informed decision you can make to make the best decision. Annette Moore: Absolutely. Yeah. Host: Yeah. I'm sorry to hear about Harvey. You were talking. Annette Moore: Yeah. Host: A little bit before, and you are just, it's been crazy with all the traveling. You can't even unload the boxes into the house. It's got to be brutal. Annette Moore: Yeah. Host: You know, looking at, looking at, going back to imagery, I think this is one component of your division that I think is just absolutely fascinating. Annette Moore: Yeah. It is. Host: When you're talking about the beautiful images we're getting from 250 miles above the space station, but all of the rest. What are we, what's the story there? What's the story of the whole imagery component of the division? Annette Moore: So, we have imagery online. We have, as I said, we're getting around the clock. And, I don't think people realize this, but over in building eight, we're getting around the clock downlink from Station. If it's still, if it's video, it's imagery, it's photo shots. We get imagery from test data, and when engineering directorate does test data, we get photos from that. I mean, we get this data around the clock. That's, it tells a story. Host: Yeah. Annette Moore: It absolutely does. That data is used for tests. It's used for engineering analysis. It's used for data analysis. It's used for capturing and telling the story for when the crew is onboard, and what's happening throughout their duration of their crew time. It's used for all of those things, and we keep that data. That imagery is stored. It's very important for us. It's very important for the crew. When they come back, and they've got that data from their flight, they can use that data to do analysis, to do some forward work. That's hugely important. It's hugely important for folks in the engineering directorate as they're making decisions about test data and what they need to tweak, what works, what doesn't work. Hugely important. Yeah. Host: Now, that's actually, I think, one of the coolest parts about the imagery department is you have these still photographers, and not only are they taking artistic photographs and the ones you see online, the films you see of rockets going up. But, it's not, the purpose isn't because it's pretty. Annette Moore: No. Host: The purpose is, like, they're taking close up pictures of hardware. Annette Moore: That's right. Host: They're taking photos of even the crew. Annette Moore: That's right. Host: Is grabbing a camera onboard and taking photos. Annette Moore: That's right. Host: Of things that don't really look too great, but it is vital for engineering purposes. Because it's, like what you said. I love that phrasing. It tells a story. All right. What's going on here? What's the layout? How can we fix it? There's a lot of, it's important, and not only to store but to keep track of, to organize. That must be a pain to organize all those images. Annette Moore: Yeah. Annette Moore: That, well, I think the folks who do that, I've walked through our area where we have all of our imagery, and the folks who are doing that, they love that. And, they, it's like you get to experience having been on station, and you are not really there. You get to experience it as they go through all of these photos, as they go through this still imagery, as they go through the video. They get to be a part of that experience. Host: Yeah. They're part of the story. Annette Moore: Yeah. Host: Because they're living through it, and they're, they have to organize it in their head and come up, like you said. Annette Moore: Yeah. Host: With a story. And, I think the, you hinted at this before, where they're putting it is called imagery online, right? Annette Moore: Yes, it is. Host: That's the repository, right? Annette Moore: It is. Host: That's where everything's going. And, it's just I use it all the time, but it's a place where you can search the images you need. Annette Moore: Yeah. Yeah. Host: So, I'm, you know, me being in PAO, I search the ones that are prettier. That we can put on the web and share with people. Annette Moore: Well, you know, you guys have a pretty cool, cool role. So, I was at the last [inaudible] launch, and you know that we have folks who travel there from PAO who are taking the pictures. And, they're taking the pictures of the launch absolutely. They're taking the pictures of the crew coming out, and they're in their gear, and they're getting ready to get on the bus to go over to the launch pad. Absolutely taking pictures of that, but you know what they're also taking pictures of? I watched one of our astronauts interact with the children of one of our crewmen who is going up. And, you capture that. That's nothing like that. You know, the time that he took with these kids. Their father was getting read to go up. You know, the time that he took with them, and there was someone capturing all of this. You know, that's, do you know what that will mean to them years from now when they look back at that? Host: Oh, yeah. Annette Moore: Yeah. Host: You know, I've talked with quite a few folks on the podcast, and sometimes it just comes down to a single moment. It comes down to, you know, I had one guest write a letter to NASA just say, "Hey, I'm trying to be an astronaut. What should I do?" Annette Moore: Yeah. Yeah. Host: And, they wrote back, and they sent something. Annette Moore: Yeah. Host: Back to her. Annette Moore: Yeah. Host: And, she's like, "Yes. I am so motivated." She dedicated her entire school career and career after that to eventually getting to the Center. Annette Moore: There's nothing that compares to the experience of the human element, one person to. Nothing that compares to that. And, the fact that we can capture that through photos, through imagery, through video, that we capture it in so many ways. That we capture that in the records that we keep and that we pass on from one program to another, that informs the next program and the next mission. Yeah. Host: So, how much of it do we, do we keep for these informational purposes, that we keep for the engineering purposes, for learning and making our systems better and assessing and stuff like that? But, and then, how much are we looking at historical photos and maybe current photos and then sharing them out? What are we doing to share with the public? Annette Moore: So, our imagery online. Anyone within the NASA community can get through that. We also have an agreement with U of H Clear Lake. So, we have some imagery and some things through U of H Clear Lake. So, they actually have some records as well on file. So, NASA, if you look in our Space Act agreement, you know, we're a public entity. We're not an entity unto ourselves, so we exist for the purpose of, you know, of furthering humans in exploration, in space, and in all of those avenues. And so, the data that we have is not just unto ourselves. Certainly, there is a proprietary piece of that data that is used for research, that's used for human exploration, that's used for the furtherment of other missions and other programs. But, there's also a portion of that data that we are obligated to make available to the public. There is a portion of that data for historical purposes that we're obligated through NARA to make available as well. And so, that data is not just something that we parse out amongst the NASA community, but that data is shared across all kinds of venues for various reasons. Research and development, engineering, scientific and data analysis, for the general public. You know, and that's absolutely obvious when you look at our education program and how we make information available through our education program. Host: That's interesting that they're obligated. That we, we have a requirement to share this stuff. Do you know how far back we have to go until it says, "Anything past this date, that's the [inaudible],"? Annette Moore: So, for your program, when you start your program up, NARA has what they call a retention schedule. So, that retention schedule says this data, this kind of data, you have to save. You have to archive it for this period of time. And, after that period of time, you're not obligated. So, our in building 412, we have data that we're obligated to hold on site, physically, on site until its retention date has passed. And, we have what's called retention schedules. Once it hits its retention schedule, then we can send it to NARA, but it has a requirement that you hold it. And, that's for a reason. So, when we sent something to NARA, once we sent it to NARA, we have to, then, retrieve it. So, if you have to retrieve that data because you want to study that for another program that's coming up. So, it costs us to store the data with NARA, and it also costs us to retrieve that data. Host: Oh, yeah. Annette Moore: So, we want to retain that data and hold on to it until we can get as much as we can out of the life of that data. Host: Yeah. Annette Moore: And then, we will pass that data on according to the retention schedules. So, there are requirements on the data, and it has retention schedules that NARA establishes for the data. Host: So, it's like, we're required to retain it here, and that makes sense because it's fresh data. We want to use it. We want to have ready access to it. Annette Moore: Absolutely. Host: Limit the cost of it. We want to protect it. That makes a lot of sense. And then, it comes to a certain point where you have to retain it for, like you said, this amount of time. And then, you go over to NARA, and then, I guess, when it goes to NARA, that's public record, and right? Annette Moore: Right. And so, you also have what are called permanent records. Host: Permanent. Annette Moore: There are things that are permanent records. So, that's in that movie, "Raiders of the Lost Ark". When he goes, you know, those are, that's permanent records. Those records will never be destroyed. So, yeah. Host: Wow. Annette Moore: Yeah. Host: Now, I can't even imagine the amount of data to be permanent. Annette Moore: So, on one of my next trips to D.C., I'm going to the National Archives because I want to see for myself. I've actually had friends who have gone to the National archives and researched generations and generations back in their family. Host: Wow. Annette Moore: Yeah. Host: Oh, because they, yeah, archive all of that stuff. Annette Moore: Yeah. Annette Moore: Oh, my gosh. Annette Moore: Yeah. Annette Moore: I can't even imagine. That's so, that's like a never-ending construction project. Annette Moore: Yeah, yeah. Annette Moore: To build more and more as more data comes in. And, yet, we're required to keep more data, and. Annette Moore: Yeah. Host: Data becomes larger. I'm thinking. Annette Moore: Yes, it does. Host: My media files are up to 4K video. Oh, my gosh, dealing with that is such a pain. Annette Moore: Yeah. Host: It takes forever to downlink from the Station, and then it takes forever to work with. I mean, I have a tight computer, but, man, that's a lot. I think, so, what's nice about having you here, Annette, is you oversee all of this, right? So, you oversee the imagery. You oversee the storage. You oversee. So, there's so much to IRD that you're directorate, that it's just unbelievable. And then, on top of that, you're CIO. You got a large responsibility. I think one of the biggest things, and it's selfish for me as an employee here, but you're looking at working with ASIS, right? And, end user, so my computer. Not only are you looking at the imagery from the station, you're looking at my computer. So, how does that work? How do we manage the information technology that we have at our desks? Annette Moore: So, I'm responsible for that, as you said, and I'm responsible for that through two contract vehicles. So, we have the enterprise contract vehicle which is through ASIS, NIX east and west. So, we have the enterprise model, and then I have local contract that provides some additional IT support to the Center. And so, that's managed through two different offices within IRD. The IC Office has the ASIS contract under them, and then the IB office which is my information management. And then, my multimedia office. I think you probably know Ed and his team. So, they manage those two separate contracts. And, I'm responsible for that for the Center. And, I take that very personally. You know, when someone says, "Well, my computer is, I'm having issues with my computer." I take that very personally. You know. Host: Yeah. Annette Moore: I'm responsible for that, and that means a lot to me. You know, I've, I call folks. "So, how's your computer? Did we fix it? Is everything okay? Follow back with me and let me know if you're not satisfied with." So, I'm responsible for that as the CIO and as the director of IRD. It's kind of like a Dr. Jekyll Mr. Hyde thing. So, as a Director of IRD, that's the provider of your IT services here at the Center. As the CIO, that's almost like the policing and enforcing. That's the policy piece, the oversight. And, you see how the two can, might sometime conflict. Host: Yeah. Yeah. Annette Moore: But, I take both of those roles very seriously. The customer experience is paramount for me. That's critical, so. Host: It's a lot to oversee. How do you do it? What's your background, by the way? Annette Moore: So, I'm, my undergrad is in double e, electrical engineering. Host: Okay. Annette Moore: And then, so here is a twist. My Masters is in Elementary Ed. Host: Whoa. Annette Moore: Yeah. Interesting story. So, as a freshman, my mom and I were just, she was my best friend going through school. And, when I got ready to graduate, she told me, she said, "You're going to major in electrical engineering." I'm like, "Why?" She said, "Because you'll do well in that, and you'll make good money. And, you'll just do well in that." Unfortunately, my mom passed of breast cancer my freshman semester that I was in college. That was such a hard blow for me. That was really hard. I almost did not make it through school, I'll tell you that. Host: Yeah. It must have been hard. Annette Moore: But, it taught me a lot. It taught me a lot about perseverance. It taught me a lot about what's important. It taught me a lot about people. So, the way I do this job is that I trust the people who do the job. And, I tell the folks in my organization, "I work for you. My job is to ensure that you have everything that you need to be successful. If you don't, then I have not done my job." And so, I very much see myself as a servant leader. I'm service oriented in making sure that the people at this center have everything that they need to do the mission and make sure that the mission is successful. So. Host: That's it. That, you do it, you don't do it all. You empower others to do it all. Annette Moore: Absolutely. Absolutely. Host: And, maintain that accountability and trust within the organization. Annette Moore: Absolutely. Host: Huge part of being a leader. Annette Moore: Yeah. I tell them, "You guys are the smart people in the room. Not me." [ Laughter ] And, I'm smart enough to know that. Host: And, I'm smart enough to let you be smart. Annette Moore: Absolutely. Host: There you go. All right. Well, Annette, that is such a nice overview of IRD. I feel like there's more that we can go into, but it's just hearing your passion for what you do and what you oversee, and not only that, but the people that you work with. It's truly inspiring. So, I appreciate you coming on the podcast today. Annette Moore: Oh, thank you so much. I appreciate you asking me to do this, and you've got it on record. I'm going to ask [inaudible] so I can get you out to the farm because I really want you to see this. It's pretty cool. It's cool. Host: That would be lovely. Thank you. Annette Moore: Yeah. Yeah. Thank you. [ Music ] Houston, go ahead. [inaudible] shuttle. Roger. [inaudible] Space for all mankind. Actually a huge honor to break a record like this. Not because they are easy, but because they are hard. Houston, welcome to space [echo]. Host: Hey, thanks for sticking around. So, today, we talked with Ms. Annette Moore about the data and information that we're dealing with in space and then also here in the Center at the NASA Johnson Space Center. Some of the places that we store imagery, deal with imagery, protect imagery, and data and information. And, it's actually incredible. This is episode 45 of the podcast. We are in no particular order. It's just, that's just how we keep track of everything. So, you can go back and listen other great podcasts on dealing with the space station and especially here on the Center. We actually talked a while back. I'm trying to remember which episode. I think it's episode 12, we talked with the Center Director, Ellen Ochoa about just what we do here in Houston. And, this is just a small part of what we do in Houston, and yet, it's so broad and huge. It's actually incredible. So, you can go listen to that one. I think it's called "Leading Human Space Exploration". I believe it's episode 12. Otherwise, you can listen to some of our other NASA podcasts. We have "Gravity Assist" hosted up at headquarters by Dr. Jim Green that talks about planetary science, and then we have our friends over in Ames Research Center for their podcast "NASA in Silicon Valley". They talk about the stuff that they're doing over there in California and helping us out with some of the research aboard the International Space Station. Otherwise, you can visit our social media sites, both the NASA Johnson Space Center accounts and International Space Station accounts on Facebook, Instagram, and Twitter. Use the hashtag ask NASA on your favorite platform to submit an idea. And then, we'll make sure to make it into an episode of "Houston, We Have a Podcast". So, this episode was recorded on April 18, 2018. Thanks to Alex Perryman, Kelly Humphries, Pat Ryan, Bill Stafford, and Eloisa Sidler. And, thanks again to Ms. Annette Moore for coming on the show. We'll be back next week.

Model Scaling of Hydrokinetic Ocean Renewable Energy Systems

NASA Astrophysics Data System (ADS)

von Ellenrieder, Karl; Valentine, William

2013-11-01

Numerical simulations are performed to validate a non-dimensional dynamic scaling procedure that can be applied to subsurface and deeply moored systems, such as hydrokinetic ocean renewable energy devices. The prototype systems are moored in water 400 m deep and include: subsurface spherical buoys moored in a shear current and excited by waves; an ocean current turbine excited by waves; and a deeply submerged spherical buoy in a shear current excited by strong current fluctuations. The corresponding model systems, which are scaled based on relative water depths of 10 m and 40 m, are also studied. For each case examined, the response of the model system closely matches the scaled response of the corresponding full-sized prototype system. The results suggest that laboratory-scale testing of complete ocean current renewable energy systems moored in a current is possible. This work was supported by the U.S. Southeast National Marine Renewable Energy Center (SNMREC).

Intraseasonal variability and tides in Makassar Strait

NASA Astrophysics Data System (ADS)

Susanto, R. Dwi; Gordon, Arnold L.; Sprintall, Janet; Herunadi, Bambang

2000-05-01

Intraseasonal variability and tides along the Makassar Strait, the major route of Indonesian throughflow, are investigated using spectral and time-frequency analyses which are applied to sea level, wind and mooring data. Semidiurnal and diurnal tides are dominant features, with higher (lower) semidiurnal (diurnal) energy in the north compared to the south. Sea levels and mooring data display intraseasonal variability which are probably a response to remotely forced Kelvin waves from the Indian Ocean through Lombok Strait and to Rossby waves from the Pacific Ocean. Sea levels in Tarakan and Balikpapan and Makassar mooring velocities reveal intraseasonal features with periods of 48-62 days associated with Rossby waves from the Sulawesi Sea. Kelvin wave features with periods of 67-100 days are seen in Bali (Lombok Strait), at the mooring sites and in Balikpapan, however, they are not seen in Tarakan, which implies that these waves diminish after passing through the Makassar Strait.

The Adventures of Captain John Smith, Pocahontas and a Sundial: Cosmology, Mathematics, and Power at the Time of Jamestown

NASA Astrophysics Data System (ADS)

Schechner, Sara J.

2007-12-01

While exploring the Chickahominy River in Virginia by canoe in December 1607, Captain John Smith was ambushed by 200 Powhatan Indians and chased into the swamp. Wounded by arrows and mired in the cold mud, Smith surrendered and was led to their chieftain, Opechancanough. Smith played for time. He pulled out his pocket sundial and proceeded to deliver a lecture on astronomy. The Indians marveled at the dancing needle of the magnetic compass, which they could plainly see but not touch because of the glass cover. They apparently thought less of his discourse in a foreign language on the sun, moon, and planets, as within the hour, Smith's captors had him tied to a tree and were ready to shoot him. But then, Opechancanough held the sundial aloft and spared Smith's life. For the next month, Smith was paraded around various Indian villages before being condemned to have his head bashed in. Pocahontas, however, threw herself across Smith's body in order to save his life. This legendary episode reveals more than Smith's ingenuity. His compass sundial, shaped and marked like a celestial globe, was a microcosm of his universe. It embodied the belief that the smallest things mirrored the large, that number was the key to God's creation, and that by means of mathematical instruments, men could dominate that world (or at least extricate themselves from tight spots!). This paper will examine the astronomical ideas and instruments on which these beliefs were based, and show how ultimately, Smith's sundial also represented the clash of two cosmologies-that of the Indians and European settlers.

Moore's law realities for recording systems and memory storage components: HDD, tape, NAND, and optical

NASA Astrophysics Data System (ADS)

Fontana, Robert E.; Decad, Gary M.

2018-05-01

This paper describes trends in the storage technologies associated with Linear Tape Open (LTO) Tape cartridges, hard disk drives (HDD), and NAND Flash based storage devices including solid-state drives (SSD). This technology discussion centers on the relationship between cost/bit and bit density and, specifically on how the Moore's Law perception that areal density doubling and cost/bit halving every two years is no longer being achieved for storage based components. This observation and a Moore's Law Discussion are demonstrated with data from 9-year storage technology trends, assembled from publically available industry reporting sources.

Moore-Federman syndrome and acromicric dysplasia: are they the same entity?

PubMed Central

Winter, R M; Patton, M A; Challener, J; Mueller, R F; Baraitser, M

1989-01-01

Four unrelated patients are reported with short stature, stiffness of the joints, short fingers, inability to make a fist, and thickened skin on the forearms. Investigations have failed to show a lysosomal storage disorder and radiographs show non-specific changes with a delayed carpal bone age. The clinical features in the four children are very similar to the recently described acromicric dysplasia. There are also similarities to Moore-Federman syndrome which has only been described in one family. The case is made that acromicric dysplasia and Moore-Federman syndrome are the same entity.

Generalized Moore Penrose Inverse of Normal Elements in a Ring with Involution

NASA Astrophysics Data System (ADS)

Titi Udjiani, SRRM; Harjito; Suryoto; Prima P, Nikken

2018-01-01

Based on the definition of a normal element in a ring with involution, it is found that each normal element is commutatively with the product of itself and the involution of itself. On the other hand, if the element of a ring with involution has generalized Moore Penrose inverse, then the element is also commutative with the product of itself and the involution of itself. In this paper, the phenomenon of the similarity properties from normal elements and generalized Moore Penrose inverse is used to establish the relationship between of them with them. .

Aerodynamic and hydrodynamic model tests of the Enserch Garden Banks floating production facility

DOE Office of Scientific and Technical Information (OSTI.GOV)

Huang, E.W.; Bauer, T.C.; Kelly, P.J.

1995-12-01

This paper presents the results of aerodynamic and hydrodynamic model tests of the Enserch Garden Banks, a semisubmersible Floating Production Facility (FPF) moored in 2,190-ft waters. During the wind tunnel tests, the steady component of wind and current forces/moments at various skew and heel axes were measured. The results were compared and calibrated against analytical calculations using techniques recommended by ABS and API. During the wave basin recommend test the mooring line tensions and vessel motions including the effects of dynamic wind and current were measured. An analytical calculation of the airgap, vessel motions, and mooring line loads were comparedmore » with wave basin model test results. This paper discusses the test objectives, test setups and agendas for wind and wave basin testing of a deepwater permanently moored floating production system. The experience from these tests and the comparison of measured tests results with analytical calculations will be of value to designers and operators contemplating the use of a semisubmersible based floating production system. The analysis procedures are aimed at estimating (1) vessel motions, (2) airgap, and (3) mooring line tensions with reasonable accuracy. Finally, this paper demonstrates how the model test results were interpolated and adapted in the design loop.« less

Advanced mooring method for installation of Enserch Garden Banks 388 FPF mooring legs

DOE Office of Scientific and Technical Information (OSTI.GOV)

Honig, H.J.; Koolwijk, W.; Scovell, D.C.

1995-12-31

In the fall of 1994 HeereMac v.o.f installed the 12 mooring legs for Enserch Exploration`s Floating Production Facility in Garden Banks Block 388 in the Gulf of Mexico with the SSCV Balder. The installation of the catenary mooring system, each leg comprising several varying sections of spiral strand wire and chain, required sufficient handling and maneuverability power of the vessel, while enough holding capacity and stiffness of the system had to be provided. The most important aspects of the actual installation of the mooring legs are explained, for example, the use of a purpose built tipping winch. The method selectedmore » by HeereMac for station-keeping the Balder was to use a minimum number of anchor lines in combination with a tug, in order to maintain position and at the same time have an easy and controlled method of maneuvering to a new position. The method of station-keeping the SSCV in this way is part of a development towards full position control with a spread of tugs. In this paper the station-keeping system is described and the offshore experiences with the system are discussed. Some future developments with respect to tug-assisted station-keeping systems are highlighted.« less

Admiralty Inlet Hub-Height Turbulence Measurements from June 2012

DOE Data Explorer

Kilcher, Levi

2012-06-18

This data is from measurements at Admiralty Head, in admiralty inlet. The measurements were made using an IMU equipped ADV mounted on a mooring, the 'Tidal Turbulence Mooring' or 'TTM'. The inertial measurements from the IMU allows for removal of mooring motion in post processing. The mooring motion has been removed from the stream-wise and vertical velocity signals (u, w). The lateral (v) velocity may have some 'persistent motion contamination' due to mooring sway. The ADV was positioned 11m above the seafloor in 58m of water at 48.1515N, 122.6858W. Units ----- - Velocity data (_u, urot, uacc) is in m/s. - Acceleration (Accel) data is in m/s^2. - Angular rate (AngRt) data is in rad/s. - The components of all vectors are in 'ENU' orientation. That is, the first index is True East, the second is True North, and the third is Up (vertical). - All other quantities are in the units defined in the Nortek Manual. Motion correction and rotation into the ENU earth reference frame was performed using the Python-based open source DOLfYN library (http://lkilcher.github.io/dolfyn/). Details on motion correction can be found there. For additional details on this dataset see the included Marine Energy Technology Symposium paper.

Implementation of Distributed Services for a Deep Sea Moored Instrument Network

NASA Astrophysics Data System (ADS)

Oreilly, T. C.; Headley, K. L.; Risi, M.; Davis, D.; Edgington, D. R.; Salamy, K. A.; Chaffey, M.

2004-12-01

The Monterey Ocean Observing System (MOOS) is a moored observatory network consisting of interconnected instrument nodes on the sea surface, midwater, and deep sea floor. We describe Software Infrastructure and Applications for MOOS ("SIAM"), which implement the management, control, and data acquisition infrastructure for the moored observatory. Links in the MOOS network include fiber-optic and 10-BaseT copper connections between the at-sea nodes. A Globalstar satellite transceiver or 900 MHz Freewave terrestrial line-of-sight RF modem provides the link to shore. All of these links support Internet protocols, providing TCP/IP connectivity throughout a system that extends from shore to sensor nodes at the air-sea interface, through the oceanic water column to a benthic network of sensor nodes extending across the deep sea floor. Exploiting this TCP/IP infrastructure as well as capabilities provided by MBARI's MOOS mooring controller, we use powerful Internet software technologies to implement a distributed management, control and data acquisition system for the moored observatory. The system design meets the demanding functional requirements specified for MOOS. Nodes and their instruments are represented by Java RMI "services" having well defined software interfaces. Clients anywhere on the network can interact with any node or instrument through its corresponding service. A client may be on the same node as the service, may be on another node, or may reside on shore. Clients may be human, e.g. when a scientist on shore accesses a deployed instrument in real-time through a user interface. Clients may also be software components that interact autonomously with instruments and nodes, e.g. for purposes such as system resource management or autonomous detection and response to scientifically interesting events. All electrical power to the moored network is provided by solar and wind energy, and the RF shore-to-mooring links are intermittent and relatively low-bandwidth connections. Thus power and wireless bandwidth are limited resources that constrain our choice of service technologies and wireless access strategy. We describe and evaluate system performance in light of actual deployment of observatory elements in Monterey Bay, and discuss how the system can be developed further. We also consider management and control strategies for the cable-to-shore observatory known as MARS ("Monterey Accelerated Research System"). The MARS cable will provide high power and continuous high-bandwidth connectivity between seafloor instrument nodes and shore, thus removing key limitations of the moored observatory. Moreover MARS functional requirements may differ significantly from MOOS requirements. In light of these differences, we discuss how elements of our MOOS moored observatory architecture might be adapted to MARS.

Extraordinary flood response of a small urban watershed to short-duration convective rainfall

USGS Publications Warehouse

Smith, J.A.; Miller, A.J.; Baeck, M.L.; Nelson, P.A.; Fisher, G.T.; Meierdiercks, K.L.

2005-01-01

The 9.1 km2 Moores Run watershed in Baltimore, Maryland, experiences floods with unit discharge peaks exceeding 1 m3 s-1 km-2 12 times yr-1, on average. Few, if any, drainage basins in the continental United States have a higher frequency. A thunderstorm system on 13 June 2003 produced the record flood peak (13.2 m3 s-1 km-2) during the 6-yr stream gauging record of Moores Run. In this paper, the hydrometeorology, hydrology, and hydraulics of extreme floods in Moores Run are examined through analyses of the 13 June 2003 storm and flood, as well as other major storm and flood events during the 2000-03 time period. The 13 June 2003 flood, like most floods in Moores Run, was produced by an organized system of thunderstorms. Analyses of the 13 June 2003 storm, which are based on volume scan reflectivity observations from the Sterling, Virginia, WSR-88D radar, are used to characterize the spatial and temporal variability of flash flood producing rainfall. Hydrology of flood response in Moores Run is characterized by highly efficient concentration of runoff through the storm drain network and relatively low runoff ratios. A detailed survey of high-water marks for the 13 June 2003 flood is used, in combination with analyses based on a 2D, depth-averaged open channel flow model (TELEMAC 2D) to examine hydraulics of the 13 June 2003 flood. Hydraulic analyses are used to examine peak discharge estimates for the 13 June flood peak, propagation of flood waves in the Moores Run channel, and 2D flow features associated with channel and floodplain geometry. ?? 2005 American Meteorological Society.

This evening marks the first presentation of the American Geophysical Union's Waldo E. Smith Award. While all other AGU awards and honors are given for excellence in scientific research in one or another of the geophysical disciplines, this award is different. The Waldo E. Smith Award is given for dedicated and extraordinary service to geophysics and AGU. It is the principal purpose of this citation to show why it is particularly appropriate that an award for service to American geophysics should be called the Waldo E. Smith Award. A secondary objective, aimed at those present tonight, is to introduce the first recipient of this award, Waldo E. Smith, Executive Director Emeritus of AGU.

Landing flying qualities evaluation criteria for augmented aircraft

NASA Technical Reports Server (NTRS)

Radford, R. C.; Smith, R.; Bailey, R.

1980-01-01

The criteria evaluated were: Calspan Neal-Smith; Onstott (Northrop Time Domain); McDonnell-Douglas Equivalent System Approach; R. H. Smith Criterion. Each criterion was applied to the same set of longitudinal approach and landing flying qualities data. A revised version of the Neal-Smith criterion which is applicable to the landing task was developed and tested against other landing flying qualities data. Results indicated that both the revised Neal-Smith criterion and the Equivalent System Approach are good discriminators of pitch landing flying qualities; Neal-Smith has particular merit as a design guide, while the Equivalent System Approach is well suited for development of appropriate military specification requirements applicable to highly augmented aircraft.

Clostridium perfringens is an important pathogen causing sudden death syndrome, necrotic enteritis, and gas gangrene in ruminants, especially some deer species. Père David's deer (Elaphurus davidianus) is one of the world's rare species and is an endangered and protected species in China. Some Père David's deer in the Chinese Shishou Père David's Deer Preserve died due to C. perfringens infection. We investigated the toxin types and C. perfringens enterotoxin-positive (cpe(+)) strains of isolated C. perfringens in Père David's deer in China. We collected 155 fecal samples from the Beijing Nanhaizi Père David's Deer Park and the Jiangsu Dafeng Père David's Deer National Nature Reserve between July 2010 and July 2011. Bacteria isolated using blood agar and mannitol agar plates were identified by Gram staining and nested PCR for 16S rRNA. We isolated C. perfringens from 41 fecal samples and used PCR amplification of five toxin genes to identify the toxinotypes and the cpe(+) strains of C. perfringens. Twenty-one isolates were type A, 15 were type E, and five were type D. Fifteen isolates were cpe(+) strains, including eight that were type A and seven that were type E.

We report the first two year of results from a 10m deep mooring over a Posidonia Oceanica seagrass meadow (Corsica, France) where we deployed from August 2006 to August 2008 an array of 3 optodes, a fluorometer and a sensor for measurements of the partial pressure of CO2 (pCO2). The oxygen data are used to compute by mass balance ecosystem metabolic performance rates (gross primary production, community respiration, net community production). The comparison with rates derived from discrete benthic incubations (every 2 months) is very satisfactory. The pCO2 data are used to assess the sink or source of atmospheric CO2 of the Posidonia Oceanica seagrass meadow. An application of such a mooring is to detect changes in the productivity of the Posidonia meadow that can be used as indicators of overall ecosystem "health" or degradation by human activities. Such a mooring can be used as an affordable and simple tool for management and sustainable development of coastal areas in the Mediterranean.

We report the first three years of results from a 10m deep mooring over a Posidonia Oceanica seagrass meadow (Corsica, France) where we deployed from August 2006 to November 2009 an array of 3 optodes. The oxygen data are used to compute by mass balance ecosystem metabolic performance rates (gross primary production (GPP), community respiration (CR), net community production (NCP)), allowing a detailed analysis of seasonal and year-to-year variability of GPP, CR and NCP. The comparison of GPP and CR values derived from the O2 mass balance with rates derived from discrete benthic incubations (every 2 months in 2006-2007, every 4 months in 2008-2009) is very satisfactory. An application of such a mooring is to detect changes in the productivity of the Posidonia meadow that can be used as indicators of overall ecosystem "health" or degradation by human activities. Such a mooring can be used as an affordable and simple tool for management and sustainable development of coastal areas in the Mediterranean.

The detrimental consequences for seagrass of ineffective marine park management related to boat anchoring.

Posidonia oceanica (L.) Delile meadows are recognized as priority habitat for conservation by the EU Habitats Directive. The La Maddalena Archipelago National Park (Mediterranean Sea) P. oceanica meadow, the dominant coastal habitat of the area, is mostly threatened by boat anchoring. 12 years after the establishment of mooring fields and anchoring restrictions, a study was conducted to measure their effectiveness on the conservation of seagrass and the mitigation of anchoring damage. We found that: (i) the condition of P. oceanica was disturbed, both in the mooring fields and in control locations; (ii) mooring fields and anchoring restrictions did not show to be an efficient system for the protection of seagrass, in fact anchor scars increased after the tourist season; (iii) the mooring systems had an impact on the surrounding area of the meadow, probably due to their misuse. On the basis of these results, management recommendations for marine parks are proposed. Copyright © 2014 Elsevier Ltd. All rights reserved.

To explore the details of Henry Hollingsworth Smith's (1815-1890) achievement as the first physician to organize in a systematic and chronologic manner the details of the history of surgery in America and prepare a register of men who performed surgical operations. The life of Smith, the earliest of the nation's surgeons to elucidate the history of American surgery, is little known. His boosting the image of the scalpel wielder helped shape the future of the craft, in particular, surgery's rise as a specialty and profession. An analysis of the published medical literature and unpublished documents relating to Smith and his work to document the history of American surgery. During the 1850 s, a time when surgery was not considered a separate branch of medicine but a mere technical mode of treatment, Smith's efforts in surgical history provided much needed encouragement to surgeons in their pursuit of professional recognition. Although Smith's accomplishment as the nation's first compiler of the history of American surgery has long been forgotten, his effort afforded the men who performed surgical operations their earliest measure of self-respect. As such, Smith belongs in America's pantheon of surgical heroes.

First Year Observations of Antarctic Circumpolar Current Variability and Internal Wave Activity from the DIMES Mooring Array

NASA Astrophysics Data System (ADS)

Brearley, J. A.; Sheen, K. L.; Naveira-Garabato, A. C.

2012-04-01

A key component of DIMES (Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean) is the deployment of a two-year cross-shaped mooring array in the Antarctic Circumpolar Current to the east of Drake Passage close to 57°W. Motivation for the cluster arises from the need to understand how eddies dissipate in the Southern Ocean, and specifically how much energy is extracted from the mesoscale by breaking internal waves, which in turn leads to turbulent mixing. The location of the mooring cluster was chosen to fulfil these objectives, being situated in a region of pronounced finestructure with high eddy kinetic energy and rough topography. The array, comprising 34 current meters and Microcats and a downward-looking ADCP, was first deployed in December 2009 and serviced in December 2010. Time series of current meter results from the most heavily-instrumented 'C' mooring indicate that a strong (up to 80 cms-1) surface-intensified north-eastward directed ACC occupies the region for most of the year, with over 85% of the variability in current speed being accounted for by equivalent barotropic fluctuations. A strong mean poleward heat flux is observed at the site, which compares favourably in magnitude with literature results from other ACC locations. Interestingly, four episodes of mid-depth (~2000 m) current speed maxima, each of a few days duration, were found during the 360-day time series, a situation also observed by the lowered ADCP during mooring servicing in December 2010. Early results indicate that these episodes, which coincide with time minima in stratification close to 2000 m, could profoundly influence the nature of eddy-internal wave interactions at these times. Quantification of the energy budget at the mooring cluster has been a key priority. When compared with previous moorings located in Drake Passage (Bryden, 1977), a near threefold-increase in mean eddy kinetic energy (EKE) is observed despite a small reduction in the mean kinetic energy between these sites. The magnitude of interactions between the available potential energy and EKE and between the EKE and mean kinetic energy are of similar magnitude to those observed in Drake Passage. Unfortunately, the collapse of two moorings early in 2010 has meant that second-year data will be required before the exchange of energy between the eddy and internal wave frequency bands can be rigorously quantified. However, data from the downward-looking ADCP between 2700 and 3400 m is starting to identify the important frequencies and mechanisms of internal wave activity.

What controls the oxidative ratio of UK peats? A multi-site study of elemental CHNO concentrations in peat cores

NASA Astrophysics Data System (ADS)

Clay, Gareth; Worrall, Fred; Masiello, Carrie

2013-04-01

The oxidative ratio (OR) is the amount of CO2 sequestered in the terrestrial biosphere for each mol of O2 produced. The OR governs the effectiveness of a terrestrial biome to mitigate the impact of anthropogenic CO2 emissions and it has been used to calculate the balance of terrestrial and oceanic carbon sinks across the globe. However, few studies have investigated the controls of the variability in OR. What factors affect OR - climate? Soil type? Vegetation type? N deposition? Land use? Land use change? Small shifts in OR could have important implications in the global partitioning of CO2 between the atmosphere, biosphere, and oceans. This study looks at peat soils from a series of sites representing a climatic transect across the UK. Duplicate peat cores were taken, along with samples of above-ground vegetation and litter, from sites in northern Scotland (Forsinard), southern Scotland (Auchencorth), northern England (Moor House; Thorne Moor) through the Welsh borders (Whixhall Moss) and Somerset levels (Westhay Moor) to Dartmoor and Bodmin Moor in the south west of England. Sub-samples of the cores were analysed for their CHNO concentrations using a Costech ECS 4010 Elemental combustion system. Using the method of Masiello et al. (2008), OR values could be calculated from these elemental concentrations. Results show that OR values of UK peats varied between 0.82 and 1.27 with a median value of 1.08 which is within the range of world soils. There were significant differences in OR of the peat between sites with the data falling into two broad groupings - Group 1: Forsinard, Auchencorth, Dartmoor and Bodmin Moor; Group 2: Moor House, Thorne Moor, Westhay Moor, Whixhall Moss. Whilst there were significant changes (p < 0.05) in elemental ratios with increasing peat depth (increasing C:N ratio and decreasing O:C ratio) there was no significant difference overall in OR with depth. This paper will explore some of the possible controlling factors on these ratios. Local vegetation was also sampled along with agricultural soils from the local area of the peat cores to compare the relative differences in different mediums. Significant differences (p < 0.01) between vegetation, agricultural soils and surface peat layers were found where vegetation had OR values of 1.03 ± 0.04 and agricultural soils had OR values of 1.15 ± 0.04. Further discussion of these results from these comparisons is also presented in this study.

Optimization of an acoustic telemetry array for detecting transmitter-implanted fish

USGS Publications Warehouse

Clements, S.; Jepsen, D.; Karnowski, M.; Schreck, C.B.

2005-01-01

The development of miniature acoustic transmitters and economical, robust automated receivers has enabled researchers to study the movement patterns and survival of teleosts in estuarine and ocean environments, including many species and age-classes that were previously considered too small for implantation. During 2001-2003, we optimized a receiver mooring system to minimize gear and data loss in areas where current action or wave action and acoustic noise are high. In addition, we conducted extensive tests to determine (1) the performance of a transmitter and receiver (Vemco, Ltd.) that are widely used, particularly in North America and Europe and (2) the optimal placement of receivers for recording the passage of fish past a point in a linear-flow environment. Our results suggest that in most locations the mooring system performs well with little loss of data; however, boat traffic remains a concern due to entanglement with the mooring system. We also found that the reception efficiency of the receivers depends largely on the method and location of deployment. In many cases, we observed a range of 0-100% reception efficiency (the percentage of known transmissions that are detected while the receiver is within range of the transmitter) when using a conventional method of mooring. The efficiency was improved by removal of the mounting bar and obstructions from the mooring line. ?? Copyright by the American Fisheries Society 2005.

Numerical modeling of a spherical buoy moored by a cable in three dimensions

NASA Astrophysics Data System (ADS)

Zhu, Xiangqian; Yoo, Wan-Suk

2016-05-01

Floating facilities have been studied based on the static analysis of mooring cables over the past decades. To analyze the floating system of a spherical buoy moored by a cable with a higher accuracy than before, the dynamics of the cables are considered in the construction of the numerical modeling. The cable modeling is established based on a new element frame through which the hydrodynamic loads are expressed efficiently. The accuracy of the cable modeling is verified with an experiment that is conducted by a catenary chain moving in a water tank. In addition, the modeling of a spherical buoy is established with respect to a spherical coordinate in three dimensions, which can suffers the gravity, the variable buoyancy and Froude-Krylov loads. Finally, the numerical modeling for the system of a spherical buoy moored by a cable is established, and a virtual simulation is proceeded with the X- and Y-directional linear waves and the X-directional current. The comparison with the commercial simulation code ProteusDS indicates that the system is accurately analyzed by the numerical modeling. The tensions within the cable, the motions of the system, and the relationship between the motions and waves are illustrated according to the defined sea state. The dynamics of the cables should be considered in analyzing the floating system of a spherical buoy moored by a cable.

Microbial communities and transformation of carbon compounds in bog soils of the taiga zone (Tomsk oblast)

Grodnitskaya, I. D.; Trusova, M. Yu.

2009-09-01

Two types of bogs were studied in Tomsk oblast—Maloe Zhukovskoe (an eutrophic peat low-moor bog) and Ozernoe (an oligotrophic peat high-moor bog). The gram-negative forms of Proteobacteria were found to be dominant and amounted to more than 40% of the total population of the microorganisms investigated. In the peat bogs, the population and diversity of the hydrolytic microbial complex, especially of the number of micromycetes, were lower than those in the mineral soils. The changes in the quantitative indices of the total microbiological activity of the bogs were established. The microbial biomass and the intensity of its respiration differed and were also related to the depth of the sampling. In the Zhukovskoe peat low-moor bog, the maximal biomass of heterotrophic microorganisms (154 μg of C/g of peat) was found in the aerobic zone at a depth of 0 to 10 cm. In the Ozernoe bog, the maximal biomass was determined in the zone of anaerobiosis at a depth of 300 cm (1947 μ g of C/g of peat). The molecular-genetic method was used for the determination of the spectrum of the methanogens. Seven unidentified dominant forms were revealed. The species diversity of the methanogens was higher in the oligotrophic high-moor bog than in the eutrophic low-moor bog.

The practise and practice of Bourdieu: the application of social theory to youth alcohol research.

PubMed

Lunnay, Belinda; Ward, Paul; Borlagdan, Joseph

2011-11-01

Some years ago Australian anthropologist David Moore criticised the predominant form of understanding youth alcohol consumption for residing with biomedical approaches that individualise and ultimately stigmatise drinking behaviour and 'ignore' the social context of consumption. Of interest here is the ongoing insufficient integration of alternative approaches to understanding young people's drinking. This paper presents theoretically informed qualitative research that investigates why young Australian females (aged 14-17) drink and how social and cultural context form the basis, rather than the periphery, of their drinking experience. We demonstrate the utility of Pierre Bourdieu's sociological framework for delving beyond the dichotomy of young people's drinking decisions as either a determination of their cultural environment or the singular result of a rational individual's independent decision-making. The paper is presented in two parts. First, we provide the interpretation, or 'practise', of Bourdieu's concepts through an outline and application of his complex theoretical constructs. Specifically, the concept of symbolic capital (or social power) is applied. Second, our explication of Bourdieu's 'practice', or epistemological contributions, offers a methodologically grounded example to other researchers seeking to attain more complete understandings of the social processes underpinning youth alcohol consumption. A sociological approach to exploring the complex relationship between drinking and contextual social factors amongst young Australian females is an unchartered area of enquiry. We contribute new theoretically supported insights to create a more complete picture of young females' drinking behaviours. Crown Copyright © 2011. Published by Elsevier B.V. All rights reserved.

Adam Smith and the Rhetoric of Style.

ERIC Educational Resources Information Center

Moran, Michael G.

Historians of rhetoric have generally accepted the view that Adam Smith rejected the principles of classical rhetoric. However, while there can be no doubt that Smith greatly truncated the five classical arts of rhetoric (invention, arrangement, style, memory, and delivery) by reducing his concerns largely to style and arrangement, he did not…

New developments in Smith-Magenis syndrome (del 17p11.2).

PubMed

Gropman, Andrea L; Elsea, Sarah; Duncan, Wallace C; Smith, Ann C M

2007-04-01

Recent clinical, neuroimaging, sleep, and molecular cytogenetic studies have provided new insights into the mechanisms leading to the Smith-Magenis phenotype and are summarized in this review. Cross sectional studies of patients with Smith-Magenis syndrome have found evidence for central and peripheral nervous system abnormalities, neurobehavioral disturbances, and an inverted pattern of melatonin secretion leading to circadian rhythm disturbance. A common chromosome 17p11.2 deletion interval spanning approximately 3.5 Mb is identified in about 70% of individuals with chromosome deletion. Recently heterozygous point mutations in the RAI1 gene within the Smith-Magenis syndrome critical region have been reported in Smith-Magenis syndrome patients without detectable deletion by fluorescent in-situ hybridization. Patients with intragenic mutations in RAI1 as well as those with deletions share most but not all aspects of the phenotype. Findings from molecular cytogenetic analysis suggest that other genes or genetic background may play a role in altering the functional availability of RAI1 for downstream effects. Further research into additional genes in the Smith-Magenis syndrome critical region will help define the role they play in modifying features or severity of the Smith-Magenis syndrome phenotype. More research is needed to translate advances in clinical research into new treatment options to address the sleep and neurobehavioral problems in this disorder.

A comparison of free weight squat to Smith machine squat using electromyography.

PubMed

Schwanbeck, Shane; Chilibeck, Philip D; Binsted, Gordon

2009-12-01

The purpose of this experiment was to determine whether free weight or Smith machine squats were optimal for activating the prime movers of the legs and the stabilizers of the legs and the trunk. Six healthy participants performed 1 set of 8 repetitions (using a weight they could lift 8 times, i.e., 8RM, or 8 repetition maximum) for each of the free weight squat and Smith machine squat in a randomized order with a minimum of 3 days between sessions, while electromyographic (EMG) activity of the tibialis anterior, gastrocnemius, vastus medialis, vastus lateralis, biceps femoris, lumbar erector spinae, and rectus abdominus were simultaneously measured. Electromyographic activity was significantly higher by 34, 26, and 49 in the gastrocnemius, biceps femoris, and vastus medialis, respectively, during the free weight squat compared to the Smith machine squat (p < 0.05). There were no significant differences between free weight and Smith machine squat for any of the other muscles; however, the EMG averaged over all muscles during the free weight squat was 43% higher when compared to the Smith machine squat (p < 0.05). The free weight squat may be more beneficial than the Smith machine squat for individuals who are looking to strengthen plantar flexors, knee flexors, and knee extensors.

Application of MOS-1 MESSR image to the investigation of wetlands in Poyang Lake

NASA Astrophysics Data System (ADS)

Chen, Shuisen; Li, Yan

1998-08-01

The lake beach and grass moor land is a kind of typical wetlands. The area varies greatly with season in Poyang Lake region. Moreover, the field investigation of wetlands is almost impossible as geographical features and difficulties in transportation. The notes address the potential role of remote sensing in the surveying of the lake beach and grass moor land. In particular, the notes reflect the characteristics relationships between MOS-1 MESSR image and the wetlands. The application results show that MOS-1 MESSR image is effective in surveying the wetland area variation and distribution (lake, river, grass moor, mud flat, sand beach, etc.). detecting lake base shape, and analyzing eco-environment surrounded.

PubMed

Kharmanda, G

2016-11-01

A new strategy of multi-objective structural optimization is integrated into Austin-Moore prosthesis in order to improve its performance. The new resulting model is so-called Improved Austin-Moore. The topology optimization is considered as a conceptual design stage to sketch several kinds of hollow stems according to the daily loading cases. The shape optimization presents the detailed design stage considering several objectives. Here, A new multiplicative formulation is proposed as a performance scale in order to define the best compromise between several requirements. Numerical applications on 2D and 3D problems are carried out to show the advantages of the proposed model.

Aalbers, A.B.; Merchant, A.A.

1996-12-31

Far East Levingston Shipbuilding (FELS) is presently completing the construction of the Smedvig Production Unit SPU 380, which will be operated as FPSO for Esso Balder Field Offshore Norway. In good cooperation with FELS and ND and A Inc. of Houston an extensive model test program was carried out for approval and optimization of the DP assisted mooring system. The main aspects were: investigate the performance of the mooring in two water depths, i.e. 250 m and 70 m; optimization of DP control for the three azimuthing thrusters; measurement of motions and wave induced loads at e.g., the bilge keels,more » keel and deckhouse front; and determination of limit sea state for turning the vessel around against the weather. The tests were carried out in the Wave and Current Basin of MARIN, using a closed loop DP control system to steer the thrusters. The paper presents the findings with respect to the effect of DP control strategy on mooring loads and presents selected results of wave induced loads on bilge keels and deck house.« less

Analysis of ecological factors limiting the destruction of high-moor peat

NASA Astrophysics Data System (ADS)

Dobrovol'skaya, T. G.; Golovchenko, A. V.; Zvyagintsev, D. G.

2014-03-01

This review presents an analysis of literature data and original studies by the authors aimed at revealing the factors inhibiting the destruction of high-moor (oligotrophic) peat. Each of the ecological factors that prevent the decomposition of the high-moor peat by different groups of microorganisms is considered. The acid reaction, low temperatures, and lack of nutrients were found not to be the primary factors inhibiting the destruction of the peat. The limited content of oxygen in the peatbogs leads to a drastic decrease in the number of mycelial microorganisms and a reduction of the activity of hydrolytic and oxidizing enzymes. The main factor inhibiting the decomposition of sphagnum is its mechanical and chemical stability, since animals crushing sphagnum are absent in the soil, and this moss has polysaccharides of special composition. The toxicity of phenol compounds, which is manifested under the aerobic conditions, prevents the activity of all the hydrolytic enzymes. This is the main reason for the slow decomposition of sphagnum peat and the long-term preservation of the residues of bodies and food in high-moor peatlands.

Lateral vibration behavior analysis and TLD vibration absorption design of the soft yoke single-point mooring system

NASA Astrophysics Data System (ADS)

Lyu, Bai-cheng; Wu, Wen-hua; Yao, Wei-an; Du, Yu

2017-06-01

Mooring system is the key equipment of FPSO safe operation. The soft yoke mooring system is regarded as one of the best shallow water mooring strategies and widely applied to the oil exploitation in the Bohai Bay in China and the Gulf of Mexico. Based on the analysis of numerous monitoring data obtained by the prototype monitoring system of one FPSO in the Bohai Bay, the on-site lateral vibration behaviors found on the site of the soft yoke subject to wave load were analyzed. ADAMS simulation and model experiment were utilized to analyze the soft yoke lateral vibration and it was determined that lateral vibration was resonance behaviors caused by wave excitation. On the basis of the soft yoke longitudinal restoring force being guaranteed, a TLD-based vibration damper system was constructed and the vibration reduction experiments with multi-tank space and multi-load conditions were developed. The experimental results demonstrated that the proposed TLD vibration reduction system can effectively reduce lateral vibration of soft yoke structures.

Elevation Measurement Profile of Mars

NASA Technical Reports Server (NTRS)

1999-01-01

The elevation measurements were collected by the Mars Orbiter Laser Altimeter (MOLA) aboard Global Surveyor during the spring and summer of 1998, as the spacecraft orbited Mars in an interim elliptical orbit. MOLA sends laser pulses toward the planet and measures the precise amount of time before the reflected signals are received back at the instrument. From this data, scientists can infer surface and cloud heights.

During its mapping of the north polar cap, the MOLA instrument also made the first direct measurement of cloud heights on the red planet. Reflections from the atmosphere were obtained at altitudes from just above the surface to more than nine miles (approximately 15 kilometers) on about 80 percent of the laser profiles. Most clouds were observed at high latitudes, at the boundary of the ice cap and surrounding terrain.

Clouds observed over the polar cap are likely composed of carbon dioxide that condenses out of the atmosphere during northern hemisphere winter. Many clouds exhibit dynamic structure probably caused by winds interacting with surface topography, much as occurs on Earth when winds collide with mountains to produce turbulence.

The principal investigator for MOLA is Dr. David E. Smith of Goddard. The MOLA instrument was designed and built by the Laser Remote Sensing Branch of Laboratory for Terrestrial Physics at Goddard. The Mars Global Surveyor Mission is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for the NASA Office of Space Science.

Trapping of Momentum due to Low Salinity Water in the north Bay of Bengal

NASA Astrophysics Data System (ADS)

Chaudhuri, D.; Tandon, A.; Farrar, T.; Weller, R. A.; Venkatesan, R.; S, S.; MacKinnon, J. A.; D'Asaro, E. A.; Sengupta, D.

2016-02-01

We study the relation between near-surface ocean stratification and upper ocean currents (momentum) during the diurnal cycle and subseasonal "active-break cycle" of the summer monsoon in the north Bay of Bengal. We use time series of hourly observations from NIOT moorings BD08, BD09 and an INCOIS mooring near 18 N, 89 E in 2013, and data collected during two research cruises of ORV Sagar Nidhi in August-September 2014 and 2015. Our analyses are based on upper ocean profiles of temperature, salinity and density (from moorings and a shipborne underway conductivity-temperature-depth profiler), velocity (Acoustic Doppler Current Profiler), and surface forcing (meterology sensors on moored buoy and ship). Monsoon breaks are characterized by low rainfall, low wind speed (0-5 m/s) and high incident shortwave radiation, whereas active phases are marked by intense rainfall, high wind speed (8-16 m/s) and low incident sunlight. Our main findings are: (i) Net surface heat flux is positive (ocean gains heat) during break spells, and sea surface temperature (SST) rises by upto 1.5 C in 1-2 weeks. (ii) During breaks, day-night SST difference can reach 1.5C; mixed layer depth (MLD) shoals to 5m during day time, and deepens to 15-20 m by late night/early morning. (iii) During active spells, SST cools on subseasonal scales; MLD is deep (exceeding 20 m), and diurnal re-stratification is weak or absent. (iv) Once very low-salinity water (<30 psu) from rivers arrives at the moorings in late August, MLD remains shallow, and is insensitive to subseasonal changes in surface forcing. (v) Moored data and high-resolution observations from the summer 2014 and 2015 cruises reveal trapping of momentum from winds in a relatively thin surface layer when surface salinity is low and the shallow stratification is strong. Results of ingoing analyses will be presented at the meeting.

Will Moores law be sufficient?

DOE Office of Scientific and Technical Information (OSTI.GOV)

DeBenedictis, Erik P.

2004-07-01

It seems well understood that supercomputer simulation is an enabler for scientific discoveries, weapons, and other activities of value to society. It also seems widely believed that Moore's Law will make progressively more powerful supercomputers over time and thus enable more of these contributions. This paper seeks to add detail to these arguments, revealing them to be generally correct but not a smooth and effortless progression. This paper will review some key problems that can be solved with supercomputer simulation, showing that more powerful supercomputers will be useful up to a very high yet finite limit of around 1021 FLOPSmore » (1 Zettaflops) . The review will also show the basic nature of these extreme problems. This paper will review work by others showing that the theoretical maximum supercomputer power is very high indeed, but will explain how a straightforward extrapolation of Moore's Law will lead to technological maturity in a few decades. The power of a supercomputer at the maturity of Moore's Law will be very high by today's standards at 1016-1019 FLOPS (100 Petaflops to 10 Exaflops), depending on architecture, but distinctly below the level required for the most ambitious applications. Having established that Moore's Law will not be that last word in supercomputing, this paper will explore the nearer term issue of what a supercomputer will look like at maturity of Moore's Law. Our approach will quantify the maximum performance as permitted by the laws of physics for extension of current technology and then find a design that approaches this limit closely. We study a 'multi-architecture' for supercomputers that combines a microprocessor with other 'advanced' concepts and find it can reach the limits as well. This approach should be quite viable in the future because the microprocessor would provide compatibility with existing codes and programming styles while the 'advanced' features would provide a boost to the limits of performance.« less

Adam Smith and dependency.

PubMed

Ozler, Sule

2012-06-01

The focus of this paper is the works and life of Adam Smith, who is widely recognized as the father and founder of contemporary economics. Latent content analysis is applied to his seminal text in economics, An Inquiry into the Nature and Causes of the Wealth of Nations (1776). The results reveal that Smith considers dependence on others a problem and sees the solution to this problem in impersonalized interdependence. In addition, his views on social dependency and personal dependency, reflected in his Lectures on Jurisprudence (1963) and The Theory of Moral Sentiments (1759), are analyzed. This analysis suggests a central tension between dependence and independence in Smith's writings. The personal dependency patterns he exhibited in his life, which also suggest a tension between dependence and independence, are identified through a reading of his biographies. Based on insights from psychoanalytic literature, this paper proposes that developing the ideas in the Wealth of Nations was part of Smith's creative solution to this tension. In particular, his solution to one individual's dependence on another was through a system of impersonalized interdependence. In other words, Smith defended against his personal dependence through his economic theorizing.

Searching for Dark Matter Annihilation in the Smith High-Velocity Cloud

NASA Technical Reports Server (NTRS)

Drlica-Wagner, Alex; Gomez-Vargas, German A.; Hewitt, John W.; Linden, Tim; Tibaldo, Luigi

2014-01-01

Recent observations suggest that some high-velocity clouds may be confined by massive dark matter halos. In particular, the proximity and proposed dark matter content of the Smith Cloud make it a tempting target for the indirect detection of dark matter annihilation. We argue that the Smith Cloud may be a better target than some Milky Way dwarf spheroidal satellite galaxies and use gamma-ray observations from the Fermi Large Area Telescope to search for a dark matter annihilation signal. No significant gamma-ray excess is found coincident with the Smith Cloud, and we set strong limits on the dark matter annihilation cross section assuming a spatially extended dark matter profile consistent with dynamical modeling of the Smith Cloud. Notably, these limits exclude the canonical thermal relic cross section (approximately 3 x 10 (sup -26) cubic centimeters per second) for dark matter masses less than or approximately 30 gigaelectronvolts annihilating via the B/B- bar oscillation or tau/antitau channels for certain assumptions of the dark matter density profile; however, uncertainties in the dark matter content of the Smith Cloud may significantly weaken these constraints.

This article traces the travels of the Scottish physician Archibald Smith through the Peruvian Andes between the 1820s and 1860s. Despite his prominent role in the nineteenth-century Peruvian medical scene, almost nothing has been written on Archibald Smith. By exploring Smith's medical activities, publications, and debates, this article intends to uncover unexplored areas of Peruvian medical history, such as the animosity between local and foreign physicians during the post-Independence war era and the important role played by medical geography as a scientific discipline for redefining ethnical and regional issues.
