Radio and distance learning in Pakistan.  

PubMed

Radio is a powerful communication vehicle in Pakistan able to reach 3/4 of urban and 2/3 of rural households. Until 1974, most radio broadcasts of the Pakistan Broadcasting Corporation, a state monopoly, were in the categories of music, drama, and features; news and current affairs; and religious broadcasts. The Allama Iqbal Open University (AIOU), a distance learning educational institution, was established through an act of the Pakistan Parliament in 1974 and is the only institution in the country to use radio broadcasts for its curriculum. Also established in 1974 within the AIOU was the Institute of Educational Technology (IET). The IET channels the transmission and flow of well-designed educational messages and lessons from the teachers to the students by employing distance teaching methodology that seeks to reinforce students' weekly lessons. IET closely integrates its activities within the University's academic departments. IET staff members not only participate in the development of course curriculum and syllabi, but also help to identify course content needing reinforcement through radio. While the teachers at AIOU convert the course curricula into distance-learning self-study activity-oriented correspondence texts, IET producers transcribe these scripts into actual production scripts. Feedback from students and findings of the University's Research and Statistical Cell are used to make revisions in the scripts. The AIOU enrolls an average of 100,000 students each year. Expansion is being limited only by the costs of purchasing time from the Pakistan Broadcasting Corporation (Rs 2000 for a 15-minute lesson) and the availability of appropriate time slots.

Opening education.

Spurred by the publication of Massachusetts Institute of Technology OpenCourseWare in 2002, the open educational resources (OER) movement, which has rapidly expanded and captured the imagination and energy of millions of creators and users throughout the world, now faces many opportunities and substantial challenges as it moves to become an integral part of the world's educational environment. The confluence of the Web and a spirit of sharing intellectual property have fueled a worldwide movement to make knowledge and education materials open to all for use. OER are content (courses, books, lesson plans, articles, etc.), tools (virtual laboratories, simulations, and games), and software that support learning and educational practice. OER are free on the Web, and most have licenses that allow copyright holders to retain ownership while providing specified rights for use in original and modified forms. At the least, OER have helped to level the distribution of knowledge across the world. A second promise of OER is to help transform educational practices. This article explores the history of and promises and challenges for OER. PMID:19119226

Although antinuclear campaigns seem to be effective, public communication and education efforts on low-level radioactive waste have mixed results. Attempts at public information programs on low-level radioactive waste still focus on influencing public opinion. A question then is: {open_quotes}Is it preferable to have a program focus on public education that will empower individuals to make informed decisions rather than trying to influence them in their decisions?{close_quotes} To address this question, a case study with both quantitative and qualitative data will be used. The Ohio Low-Level Radioactive Waste Education Program has a goal to provide people with information they want/need to make their own decisions. The program initiated its efforts by conducting a statewide survey to determine information needed by people and where they turned for that information. This presentation reports data from the survey and then explores the program development process in which programs were designed and presented using the information. Pre and post data from the programs reveal attitude and knowledge shifts.

Ladies and Gentlemen To quote Mr Jean Terrien: "Physics must be one step ahead of metrology". A long-serving Director of the BIPM, he said these words when visiting the IMGC in 1970 as a member of the scientific board of our Institute. At that time it was still an open question whether the IMGC should start research work on the absolute measurement of silicon lattice spacing. Mr Terrien underlined the revolutionary character of x-ray interferometry and, eventually, he caused the balance needle to lean towards the ... right direction. Mr Terrien correctly foresaw that, like Michelson's interferometer of 1880, x-ray interferometry could have a prominent place in today's science and technology. And while, in the first case, after more than a century we can see instruments based on electromagnetic wave interaction within every one's reach in laboratories and, sometimes, in workshops, in the second case, twenty-five years since the first development of an x-ray interferometer we can witness its role in nanometrology. Today and tomorrow we meet to discuss how to go beyond the sixth decimal place in the value of the Avogadro constant. We are aware that the quest for this achievement requires the cooperation of scientists with complementary capabilities. I am sure that the present workshop is a very good opportunity to present and discuss results and to improve and extend existing cooperation. The new adjustment of fundamental constants envisaged by the CODATA Task Group is redoubling scientists' efforts to produce competitive values of NA. The results of the measurements of the silicon lattice spacing in terms of an optical wavelength, which were available for the 1986 adjustment, combined with the determination of silicon molar volume, demonstrate how such an NA determination produces a consistent set of other constants and opens the way to a possible redefinition of the kilogram. We shall see in these two days how far we have progressed along this road. For us at the IMGC this is an extremely valuable opportunity to compare our results with others using combined x-ray and optical interferometry to measure Si lattice spacing and dimensional and mass metrology to determine Si density. The initial impetus for the organization of this workshop was given by several colleagues, and with special emphasis and competence by the late Prof. Peter Seyfried of the PTB. We all mourn the loss of such a distinguished scientist to whom very important achievements in NA determination have to be credited. Prof. Seyfried was well known at the IMGC, some of our scientists having very profitably cooperated with him and his co-workers—a cooperation that is being steadily carried on. I wish to acknowledge the endorsements of the Regione Piemonte, of the CNR, of Turin University, and of the Commission of the European Communities, in terms of grants and other resources without which the workshop could not have been realized. I also wish to very warmly thank my colleagues on the Organizing Committee who have worked so well for this event. Lastly, I am pleased to acknowledge the fruitful cooperation between the IMGC and the Istituto di Fisica Generale "A Avogadro"—not the first case of its kind and, I am convinced, not the last. To conclude, let me draw your attention to an enlargement of an Italian stamp commemorating A Avogadro. The statement reads: "Equal volumes of gas in the same temperature and pressure conditions contain the same number of molecules". He simply stated the existence of such a number, leaving us with the pleasure of measuring it.

Open Rotor Aeroacoustic Modeling  

NASA Technical Reports Server (NTRS)

Owing to their inherent fuel efficiency, there is renewed interest in developing open rotor propulsion systems that are both efficient and quiet. The major contributor to the overall noise of an open rotor system is the propulsor noise, which is produced as a result of the interaction of the airstream with the counter-rotating blades. As such, robust aeroacoustic prediction methods are an essential ingredient in any approach to designing low-noise open rotor systems. To that end, an effort has been underway at NASA to assess current open rotor noise prediction tools and develop new capabilities. Under this effort, high-fidelity aerodynamic simulations of a benchmark open rotor blade set were carried out and used to make noise predictions via existing NASA open rotor noise prediction codes. The results have been compared with the aerodynamic and acoustic data that were acquired for this benchmark open rotor blade set. The emphasis of this paper is on providing a summary of recent results from a NASA Glenn effort to validate an in-house open noise prediction code called LINPROP which is based on a high-blade-count asymptotic approximation to the Ffowcs-Williams Hawkings Equation. The results suggest that while predicting the absolute levels may be difficult, the noise trends are reasonably well predicted by this approach.

Demystifying Open Access

The tenets of Open Access are to grant anyone, anywhere and anytime free access to the results of scientific research. HEP spearheaded the Open Access dissemination of scientific results with the mass mailing of preprints in the pre-WWW era and with the launch of the arXiv preprint system at the dawn of the '90s. The HEP community is now ready for a further push to Open Access while retaining all the advantages of the peer-review system and, at the same time, bring the spiralling cost of journal subscriptions under control. I will present a possible plan for the conversion to Open Access of HEP peer-reviewed journals, through a consortium of HEP funding agencies, laboratories and libraries: SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics). SCOAP3 will engage with scientific publishers towards building a sustainable model for Open Access publishing, which is as transparent as possible for HEP authors. The current system in which journals income comes from subscription fees is replaced with a scheme where SCOAP3 compensates publishers for the costs incurred to organise the peer-review service and give Open Access to the final version of articles. SCOAP3 will be funded by all countries active in HEP under a 'fair share' scenario, according to their production of HEP articles. In this talk I will present a short overview of the history of Open Access in HEP, the details of the SCOAP3 model and the outlook for its implementation.

I will present a possible plan for the conversion to Open Access of HEP peer-reviewed journals, through a consortium of HEP funding agencies, laboratories and libraries: SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics). SCOAP3 will engage with scientific publishers towards building a sustainable model for Open Access publishing, which is as transparent as possible for HEP authors. The current system in which journals income comes from subscription fees is replaced with a scheme where SCOAP3 compensates publishers for the costs incurred to organise the peer-review service and give Open Access to the final version of articles. SCOAP3 will be funded by all countries active in HEP under a "fair share" scenario, according to their production of HEP articles. In this talk I will present a short overview of the history of Open Access in HEP, the details of the SCOAP3 model and the outlook for its implementation.

Over recent years, there has been a strong trend towards designing open space offices. One of the driving forces is the notion of the office as a site primarily for knowledge sharing. Yet designers interpret the value of openness in different ways, resulting in different outcomes and opportunities for interaction. To understand the interplay between spatial form and social life

In Praise of Openness  

NASA Astrophysics Data System (ADS)

Open access brings greater visibility and impact to the work of scientists as is evidenced in the examples discussed in this paper. Researchers are often reluctant and afraid to deposit their works in Institutional Repositories. However, as is shown here, once they do so, they do not regret it. Open access will shortly become the norm and will be accepted by the vast majority of scientists. Seen through the lens of the philosophy of Bertrand Russell, the moral, economic and philosophical imperatives for open access are indeed strong.

Open cycle thermoacoustics  

SciTech Connect

A new type of thermodynamic device combining a thermodynamic cycle with the externally applied steady flow of an open thermodynamic process is discussed and experimentally demonstrated. The gas flowing through this device can be heated or cooled in a series of semi-open cyclic steps. The combination of open and cyclic flows makes possible the elimination of some or all of the heat exchangers (with their associated irreversibility). Heat is directly exchanged with the process fluid as it flows through the device when operating as a refrigerator, producing a staging effect that tends to increase First Law thermodynamic efficiency. An open-flow thermoacoustic refrigerator was built to demonstrate this concept. Several approaches are presented that describe the physical characteristics of this device. Tests have been conducted on this refrigerator with good agreement with a proposed theory.

OpenTopography  

NASA Astrophysics Data System (ADS)

OpenTopography is a cyberinfrastructure-based facility for online access to high-resolution topography and tools. The project is an outcome of the Geosciences Network (GEON) project, which was a research project funded several years ago in the US to investigate the use of cyberinfrastructure to support research and education in the geosciences. OpenTopography provides online access to large LiDAR point cloud datasets along with services for processing these data. Users are able to generate custom DEMs by invoking DEM services provided by OpenTopography with custom parameter values. Users can track the progress of their jobs, and a private myOpenTopo area retains job information and job outputs. Data available at OpenTopography are provided by a variety of data acquisition groups under joint agreements and memoranda of understanding (MoU). These include national facilities such as the National Center for Airborne Lidar Mapping, as well as local, state, and federal agencies. OpenTopography is also being designed as a hub for high-resolution topography resources. Datasets and services available at other locations can also be registered here, providing a "one-stop shop" for such information. We will describe the OpenTopography system architecture and its current set of features, including the service-oriented architecture, a job-tracking database, and social networking features. We will also describe several design and development activities underway to archive and publish datasets using digital object identifiers (DOIs); create a more flexible and scalable high-performance environment for processing of large datasets; extend support for satellite-based and terrestrial lidar as well as synthetic aperture radar (SAR) data; and create a "pluggable" infrastructure for third-party services. OpenTopography has successfully created a facility for sharing lidar data. In the next phase, we are developing a facility that will also enable equally easy and successful sharing of services related to these data.

Open-Source Colorimeter  

PubMed Central

The high cost of what have historically been sophisticated research-related sensors and tools has limited their adoption to a relatively small group of well-funded researchers. This paper provides a methodology for applying an open-source approach to design and development of a colorimeter. A 3-D printable, open-source colorimeter utilizing only open-source hardware and software solutions and readily available discrete components is discussed and its performance compared to a commercial portable colorimeter. Performance is evaluated with commercial vials prepared for the closed reflux chemical oxygen demand (COD) method. This approach reduced the cost of reliable closed reflux COD by two orders of magnitude making it an economic alternative for the vast majority of potential users. The open-source colorimeter demonstrated good reproducibility and serves as a platform for further development and derivation of the design for other, similar purposes such as nephelometry. This approach promises unprecedented access to sophisticated instrumentation based on low-cost sensors by those most in need of it, under-developed and developing world laboratories. PMID:23604032

rOpenSci - open tools for open science  

NASA Astrophysics Data System (ADS)

Solving many of the basic and applied challenges in ecology and evolution requires access to large amounts of data, often spanning long spatial and temporal scales. The long-established model where researchers collect and analyze their own data will soon be replaced by one where disparate datasets are brought to bear on both basic and applied problems. As science becomes more data-driven, it faces a whole new set of challenges. Researchers will not only have to maintain expertise in their domains but also learn new skills to curate, retrieve, and analyze these newly available data. In order to fully realize the potential of data-driven science and allow researchers to draw insights from these vast data stores, we need to address challenges associated with all aspects of the research life cycle. To foster and support a new generation of data-driven science, my colleagues and I founded a project called rOpenSci (http://ropensci.org). The project is an integrated effort to build tools and training using Ecology and Evolution as a model community. In this talk I will outline several of the barriers that need to be overcome including better incentive mechanisms for data, training gaps, and lowering technical barriers.

Background The Blue Obelisk movement was established in 2005 as a response to the lack of Open Data, Open Standards and Open Source (ODOSOS) in chemistry. It aims to make it easier to carry out chemistry research by promoting interoperability between chemistry software, encouraging cooperation between Open Source developers, and developing community resources and Open Standards. Results This contribution looks back on the work carried out by the Blue Obelisk in the past 5 years and surveys progress and remaining challenges in the areas of Open Data, Open Standards, and Open Source in chemistry. Conclusions We show that the Blue Obelisk has been very successful in bringing together researchers and developers with common interests in ODOSOS, leading to development of many useful resources freely available to the chemistry community.

Open accelerating structures  

SciTech Connect

An ''Open'' Accelerating Structure must first perform the mode matching function of any accelerating structure, i.e., it must couple an incoming free field to an accelerating mode. The simplest open periodic structure that can be considered is a grating. There has been an attempt to employ an inverse Purcell effect by illuminating a grating from directly above with plane parallel light and passing the particles over the surface of the grating at right angles to the lines. Unfortunately, it has been shown by the Lawson theorem that these geometries fail to accelerate relativistic particles. This paper will restate Lawson's theorem but show that it applies only to the simple two-dimensional situation. It is shown that accelerating fields above grating can be made to fall off exponentially from that surface. Several structures are examined that deal with the problem of fields spreading over the whole grating surface.

Why should Industry care? They should care because we in Government want the best Industry has to offer. Industry is in the business of pushing technology to greater and greater capabilities through innovation. Examples of innovations are on full display at this conference, such as exploring the impact of difficult environmental conditions on technical performance. Industry is creating the tools which will continue to give the Navy and Marine Corps important tactical advantages over our adversaries.

Open scientific communication urged  

NASA Astrophysics Data System (ADS)

In a report released last week the National Academy of Sciences' Panel on Scientific Communication and National Security concluded that the ‘limited and uncertain benefits’ of controls on the dissemination of scientific and technological research are ‘outweighed by the importance of scientific progress, which open communication accelerates, to the overall welfare of the nation.’ The 18-member panel, chaired by Dale R. Corson, president emeritus of Cornell University, was created last spring (Eos, April 20, 1982, p. 241) to examine the delicate balance between open dissemination of scientific and technical information and the U.S. government's desire to protect scientific and technological achievements from being translated into military advantages for our political adversaries.The panel dealt almost exclusively with the relationship between the United States and the Soviet Union but noted that there are ‘clear problems in scientific communication and national security involving Third World countries.’ Further study of this matter is necessary.

Triggered plasma opening switch  

SciTech Connect

A triggerable plasma opening switch for connecting a megavolt, megampere power supply to a load is described comprising: cathode means having an input end, an output end, and a switch portion between the ends; anode means having an input end, an output end, and a switch portion between the ends and spaced from the switch portion of the cathode means by a gap; whereby the power supply is connectable between the input ends and the load is connectable between the output ends; plasma source means for filling the gap with a plasma for providing a current path for shorting current from the load; and triggering means for generating a magnetic field for controllably moving the plasma away from one of the anode or the cathode to generate an insulating gap and to block the electron flow across the gap, thereby opening the switch and permitting current to flow from the power supply to the load.

Plasma opening switch  

DOEpatents

A command triggered plasma opening switch assembly using an amplification stage. The assembly surrounds a coaxial transmission line and has a main plasma opening switch (POS) close to the load and a trigger POS upstream from the main POS. The trigger POS establishes two different current pathways through the assembly depended on whether it has received a trigger current pulse. The initial pathway has both POS's with plasma between their anodes and cathodes to form a short across the transmission line and isolating the load. The final current pathway is formed when the trigger POS receives a trigger current pulse which energizes its fast coil to push the conductive plasma out from between its anode and cathode, allowing the main transmission line current to pass to the fast coil of the main POS, thus pushing its plasma out the way so as to establish a direct current pathway to the load.

Open Architecture Network  

NSDL National Science Digital Library

The Open Architecture Network site starts things off with a bold and passionate statement: "Le Corbusier had it all wrong". It's definitely a good way to get visitors" attention upon entering the site. The Network is an online, open source community which seeks to improve living conditions through innovative and sustainable design. On the site, visitors can share their design ideas and plans, review and comment on posted designs, and also collaborate with each other. Visitors will no doubt get exited about the "Projects" section, which is both intellectually stimulating and well-designed. Visitors can search the projects by status, region, location, or theme, or they can also perform a keyword search as well. There are some wonderful finds here, including a childcare school in Sri Lanka, a day laborer shelter, and a "Doc-in-a-Box", which is meant to serve as a mobile health care center.

Open Humanities Press  

NSDL National Science Digital Library

As more and more journals elect to move to an open-source model, it is delightful to learn about the existence of the Open Humanities Press (OHP). Their mission is "to make leading works of contemporary critical thought freely available worldwide." First-time visitors will want to look over the "About OHP" section before delving into the rest of the site. Afterwards, they should feel free to look through one of their seven journals, which include "Cosmos and History", "Culture Machine", "Film-Philosophy", and "Fibreculture". While all of the journals are worth a look, the "Film-Philosophy" journal is particularly compelling, and visitors can browse through issues back to 1997. Finally, visitors can also learn about submitting their work for consideration and also take in a few essays about the guiding principles and history of the OHP.

Open quantum system identification  

E-print Network

Engineering quantum systems offers great opportunities both technologically and scientifically for communication, computation, and simulation. The construction and operation of large scale quantum information devices presents a grand challenge and a major issue is the effective control of coherent dynamics. This is often in the presence of decoherence which further complicates the task of determining the behaviour of the system. Here, we show how to determine open system Markovian dynamics of a quantum system with restricted initialisation and partial output state information.

Open Lung Biopsy  

PubMed Central

Steady improvement in the diagnostic appraisal of obscure pulmonary and mediastinal disease has permitted more intelligent treatment, better prognosis, and where necessary more accurate assessment of compensability. Open lung biopsy is designed to obtain material for pathological study when there is no pleural, mediastinal, or airway lesion on which to base a working diagnosis. A study of 54 patients in whom lung biopsy was performed at the Toronto General Hospital and Weston Sanatorium is reported. A positive tissue diagnosis was obtained in approximately 75%. The procedure is considered relatively innocuous if sensible selection is exercised to exclude patients with terminal disease, particularly that associated with severe cardiorespiratory insufficiency. No major complications occurred in this series. It is concluded that open lung biopsy might reasonably receive much wider application than in the past in cases in which a definite diagnosis cannot otherwise be made.

An opening electromagnetic transducer  

NASA Astrophysics Data System (ADS)

Tubular solenoids have been widely used without any change since an electrical wire was discovered to create magnetic fields by Hans Christian Oersted in 1820 and thereby the wire was first coiled as a helix into a solenoid coil by William Sturgeon in 1823 and was improved by Joseph Henry in 1829 [see http://www.myetymology.com/encyclopedia/History_of_the_electricity.html; J. M. D. Coey, Magnetism and Magnetic Materials (Cambridge University Press, New York, 2010); and F. Winterberg, Plasma Phys. 8, 541553 (1996)]. A magnetic control method of C-shaped carrying-current wire is proposed, and thereby a new opening electromagnetic transducer evidently differing from the traditional tubular solenoid is created, capable of directly encircling and centering the acted objects in it, bringing about convenient and innovative electromagnetic energy conversion for electromagnetic heating, electromagnetic excitation, physical information capture, and electro-mechanical motion used in science research, industry, and even biomedical activities.

High-performance buildings require an integrated design approach for all systems to work together optimally; systems integration needs to be incorporated in the earliest stages of design for efforts to be cost and energy-use effective. Building designers need a full-featured software framework to support rigorous, multidisciplinary building simulation. An open source framework - the OpenStudio Software Development Kit (SDK) - is being developed to address this need. In this paper, we discuss the needs that drive OpenStudio's system architecture and goals, provide a development status report (the SDK is currently in alpha release), and present a brief case study that illustrates its utility and flexibility.

Partially Opened Oven on Phoenix  

NASA Technical Reports Server (NTRS)

This view from the Robotic Arm Camera on NASA's Phoenix Mars Lander shows partial opening of doors to one of the tiny ovens of the Thermal and Evolved-Gas Analyzer.

Each oven has a pair of spring-loaded doors. Near the center of the image, the partial opening of a pair of doors reveals screen over the opening where a soil sample will be delivered. The door to the right is fully opened and the one to the left is partially deployed. The doors are 10 centimeters (4 inches) long. The opening is 4 centimeters (1.5 inches) wide.

Tests on the Phoenix testbed at the University of Arizona, Tucson, indicate that a soil sample could be delivered into the oven through the partially opened doors. Engineers are also exploring possibilities for opening the doors more completely.This image was taken during Phoenix's eighth Martian day, or sol (June 2, 2008).

The Phoenix Mission is led by the University of Arizona, Tucson, on behalf of NASA. Project management of the mission is by NASA's Jet Propulsion Laboratory, Pasadena, Calif. Spacecraft development is by Lockheed Martin Space Systems, Denver.

NASA Open Rotor Noise Research  

NASA Technical Reports Server (NTRS)

Owing to their inherent fuel burn efficiency advantage compared with the current generation high bypass ratio turbofan engines, there is resurgent interest in developing open rotor propulsion systems for powering the next generation commercial aircraft. However, to make open rotor systems truly competitive, they must be made to be acoustically acceptable too. To address this challenge, NASA in collaboration with industry is exploring the design space for low-noise open rotor propulsion systems. The focus is on the system level assessment of the open rotors compared with other candidate concepts like the ultra high bypass ratio cycle engines. To that end there is an extensive research effort at NASA focused on component testing and diagnostics of the open rotor acoustic performance as well as assessment and improvement of open rotor noise prediction tools. In this presentation and overview of the current NASA research on open rotor noise will be provided. Two NASA projects, the Environmentally Responsible Aviation Project and the Subsonic Fixed Wing Project, have been funding this research effort.

First Monday: Open Access Publishing

The peer-reviewed Internet journal, First Monday (discussed in the August 23, 1996 Scout Report), presents a dreary picture for open access publishing and research. The author of this article, Joseph J. Esposito, comments on The Unexpected Future of Open Access Publishing. Esposito is skeptical of the idea that the age of the Internet and online publishing will bring access to the world's research publications free for everyone, "by shifting the costs to other places in the value chain and disintermediating publishers." Instead, he argues that Open Access will come about at the cost of authors and their proxies. The author details his argument regarding these unanticipated outcomes in this article.

Background New experimental methods must be developed to study interaction networks in systems biology. To reduce biological noise, individual subjects, such as single cells, should be analyzed using high throughput approaches. The measurement of several correlative physical properties would further improve data consistency. Accordingly, a considerable quantity of data must be acquired, correlated, catalogued and stored in a database for subsequent analysis. Results We have developed openBEB (open Biological Experiment Browser), a software framework for data acquisition, coordination, annotation and synchronization with database solutions such as openBIS. OpenBEB consists of two main parts: A core program and a plug-in manager. Whereas the data-type independent core of openBEB maintains a local container of raw-data and metadata and provides annotation and data management tools, all data-specific tasks are performed by plug-ins. The open architecture of openBEB enables the fast integration of plug-ins, e.g., for data acquisition or visualization. A macro-interpreter allows the automation and coordination of the different modules. An update and deployment mechanism keeps the core program, the plug-ins and the metadata definition files in sync with a central repository. Conclusions The versatility, the simple deployment and update mechanism, and the scalability in terms of module integration offered by openBEB make this software interesting for a large scientific community. OpenBEB targets three types of researcher, ideally working closely together: (i) Engineers and scientists developing new methods and instruments, e.g., for systems-biology, (ii) scientists performing biological experiments, (iii) theoreticians and mathematicians analyzing data. The design of openBEB enables the rapid development of plug-ins, which will inherently benefit from the “house keeping” abilities of the core program. We report the use of openBEB to combine live cell microscopy, microfluidic control and visual proteomics. In this example, measurements from diverse complementary techniques are combined and correlated. PMID:24666611

Open Mushrooms: Stickiness revisited  

E-print Network

We investigate mushroom billiards, a class of dynamical systems with sharply divided phase space. For typical values of the control parameter of the system $\\rho$, an infinite number of marginally unstable periodic orbits (MUPOs) exist making the system sticky in the sense that unstable orbits approach regular regions in phase space and thus exhibit regular behaviour for long periods of time. The problem of finding these MUPOs is expressed as the well known problem of finding optimal rational approximations of a real number, subject to some system-specific constraints. By introducing a generalized mushroom and using properties of continued fractions, we describe a zero measure set of control parameter values $\\rho\\in(0,1)$ for which all MUPOs are destroyed and therefore the system is less sticky. The open mushroom (billiard with a hole) is then considered in order to quantify the stickiness exhibited and exact leading order expressions for the algebraic decay of the survival probability function $P(t)$ are ca...

Laparoscopic Versus Open Colorectal Surgery  

PubMed Central

Objective The primary endpoint was to compare the impact of laparoscopic and open colorectal surgery on 30-day postoperative morbidity. Lymphocyte proliferation to mitogens and gut oxygen tension were surrogate endpoints. Summary Background Data Evidence-based proof of the effect of laparoscopic colorectal surgery on immunometabolic response and clinically relevant outcome variables is scanty. Further randomized trials are desirable before proposing laparoscopy as a superior technique. Methods Two hundred sixty-nine patients with colorectal disease were randomly assigned to laparoscopic (n = 136) or open (n = 133) colorectal resection. Four trained members of the surgical staff who were not involved in the study registered postoperative complications. Lymphocyte proliferation to Candida albicans and phytohemagglutinin was evaluated before and 3 and 15 days after surgery. Operative gut oxygen tension was monitored continuously by a polarographic microprobe. Results In the laparoscopic group the conversion rate was 5.1%. The overall morbidity rate was 20.6% in the laparoscopic group and 38.3% in the open group. Postoperative infections occurred in 15 of the 136 patients in the laparoscopic group and 31 of the 133 patients in the open group. The mean length of hospital stay was 10.4 ± 2.9 days in the laparoscopic group and 12.5 ± 4.1 days in the open group. On postoperative day 3, lymphocyte proliferation was impaired in both groups. Fifteen days after surgery, the proliferation index returned to baseline values only in the laparoscopic group. Intraoperative gut oxygen tension was higher in the laparoscopic than in the open group. Conclusions Laparoscopic colorectal surgery resulted in a significant reduction of 30-day postoperative morbidity. Lymphocyte proliferation and gut oxygen tension were better preserved in the laparoscopic group than in the open group. PMID:12454514

Veratridine modifies open sodium channels  

PubMed Central

The state dependence of Na channel modification by the alkaloid neurotoxin veratridine was investigated with single-channel and whole- cell voltage-clamp recording in neuroblastoma cells. Several tests of whole-cell Na current behavior in the presence of veratridine supported the hypothesis that Na channels must be open in order to undergo modification by the neurotoxin. Modification was use dependent and required depolarizing pulses, the voltage dependence of production of modified channels was similar to that of normal current activation, and prepulses that caused inactivation of normal current had a parallel effect on the generation of modified current. This hypothesis was then examined directly at the single-channel level. Modified channel openings were easily distinguished from normal openings by their smaller current amplitude and longer burst times. The modification event was often seen as a sudden, dramatic reduction of current through an open Na channel and produced a somewhat flickery channel event having a mean lifetime of 1.6 s at an estimated absolute membrane potential of -45 mV (23 degrees C). The modified channel had a slope conductance of 4 pS, which was 20-25% the size of the slope conductance of normal channels with the 300 mM NaCl pipette solution used. Most modified channel openings were initiated by depolarizing pulses, began within the first 10 ms of the depolarizing step, and were closely associated with the prior opening of single normal Na channels, which supports the hypothesis that modification occurs from the normal open state.

The VLT Opening Symposium  

NASA Astrophysics Data System (ADS)

Scientists Meet in Antofagasta to Discuss Front-Line Astrophysics To mark the beginning of the VLT era, the European Southern Observatory is organizing a VLT Opening Symposium which will take place in Antofagasta (Chile) on 1-4 March 1999, just before the start of regular observations with the ESO Very Large Telescope on April 1, 1999. The Symposium occupies four full days and is held on the campus of the Universidad Catolica del Norte. It consists of plenary sessions on "Science in the VLT Era and Beyond" and three parallel Workshops on "Clusters of Galaxies at High Redshift" , "Star-way to the Universe" and "From Extrasolar Planets to Brown Dwarfs" . There will be many presentations of recent work at the major astronomical facilities in the world. The meeting provides a very useful forum to discuss the latest developments and, in this sense, contributes to the planning of future research with the VLT and other large telescopes. The symposium will be opened with a talk by the ESO Director General, Prof. Riccardo Giacconi , on "Paranal - an observatory for the 21st century". It will be followed by reports about the first scientific results from the main astronomical instruments on VLT UT1, FORS1 and ISAAC. The Symposium participants will see the VLT in operation during special visits to the Paranal Observatory. Press conferences are being arranged each afternoon to inform about the highlights of the conference. After the Symposium, there will be an Official Inauguration Ceremony at Paranal on 5 March Contributions from ESO ESO scientists will make several presentations at the Symposium. They include general reviews of various research fields as well as important new data and results from the VLT that show the great potential of this new astronomical facility. Some of the recent work is described in this Press Release, together with images and spectra of a large variety of objects. Note that all of these data will soon become publicly available via the VLT Archive. The text below summarizes the individual projects. Comprehensive texts with all photos and diagrammes are available in nine separate web documents ( ESO PR Photos 08/99 to 16/99 ) that may be accessed via the links at the top of each section. The degree of detail and level of complexity of the texts depend on the subject and the available materials. 1. Dwarf Galaxies in the Local Group ESO PR Photo 10a/99 ESO PR Photo 10a/99 The Antlia Galaxy (FORS1 colour composite) . Access full text and PR Photos 10a-d/99 In addition to large spiral galaxies like the Milky Way Galaxy, the Andromeda Galaxy and Messier 33, the Local Group of Galaxies contains many dwarf galaxies. The VLT has observed two of these, Antlia and NGC 6822 . Antlia is a low-surface brightness, spheroidal dwarf galaxy that was only discovered in 1997. While it contains a large amount of atomic hydrogen at its centre, no young stars are found, and it appears that most of its stars are old. This is unlike other dwarf galaxies in the Milky Way neighbourhood, as star formation is expected to occur within dense hydrogen clouds. Further observations will be necessary to understand this unusual characteristics. The VLT also obtained images of an irregular dwarf galaxy in the Local Group, NGC 6822, as well as spectra of some of its stars. This galaxy is of the "irregular" type and is situated at a distance of about 2 million light-years. A comparison of the spectra of supergiant stars in NGC 6822 shows that many spectral lines are much weaker than in stars of similar type in the Milky Way, but of similar strength as in stars in the Small Magellanic Cloud. This confirms an earlier finding that NGC 6822 has chemical composition (a lower "metallicity") that is different from what is observed in our Galaxy. 2.

Topics in Open Topological Strings  

E-print Network

This thesis is based on some selected topics in open topological string theory which I have worked on during my Ph.D. It comprises an introductory part where I have focused on the points most needed for the later chapters, trading completeness for conciseness and clarity. Then, following [12], we discuss tadpole cancellation for topological strings where we mainly show how its implementation is needed for ensuring the same "odd" moduli decoupling encountered in the closed theory. Next we move to analyse how the open and closed effective field theories for the B model interact writing the complete Lagrangian. We first check it deriving some already known tree level amplitudes in term of target space quantities, and then we extend the recipe to new results; later we implement open closed duality from a target field theory perspective. This last subject is also analysed from a worldsheet point of view extending the analysis of [13]. Some ideas for future research are briefly reported.

Open Syntaxin Docks Synaptic Vesicles  

PubMed Central

Synaptic vesicles dock to the plasma membrane at synapses to facilitate rapid exocytosis. Docking was originally proposed to require the soluble N-ethylmaleimide–sensitive fusion attachment protein receptor (SNARE) proteins; however, perturbation studies suggested that docking was independent of the SNARE proteins. We now find that the SNARE protein syntaxin is required for docking of all vesicles at synapses in the nematode Caenorhabditis elegans. The active zone protein UNC-13, which interacts with syntaxin, is also required for docking in the active zone. The docking defects in unc-13 mutants can be fully rescued by overexpressing a constitutively open form of syntaxin, but not by wild-type syntaxin. These experiments support a model for docking in which UNC-13 converts syntaxin from the closed to the open state, and open syntaxin acts directly in docking vesicles to the plasma membrane. These data provide a molecular basis for synaptic vesicle docking. PMID:17645391

Open Access (OA) in scholarly literature means the "immediate, free availability on the public internet, permitting any users to read, download, copy, distribute, print, search or link to the full text of these articles". The Open Access movement has been made possible thanks to the wide-spread availability of internet access and has received increasing interest since the 1990s, mostly due to the fast rising journal subscription prices. This presentation will review the current situation of Open Access in astronomy. It will answer the question why it makes sense to publish in an OA journal and will provide criteria to judge the quality of OA journals and publishers, along with suggestions how to identify so-called predatory publishers.

The Open Quantum Brownian Motion  

E-print Network

Using quantum parallelism on random walks as original seed, we introduce new quantum stochastic processes, the open quantum Brownian motions. They describe the behaviors of quantum walkers -- with internal degrees of freedom which serve as random gyroscopes -- interacting with series of probes. These processes may also be viewed as the scaling limit of open quantum random walks and we develop this approach along three different lines: quantum trajectory, quantum dynamical map, and quantum stochastic differential equation. We also present a study of the simplest case, with a two level system as internal gyroscope, illustrating the interplay between ballistic and diffusive behaviors at work in these processes.

OOI's Cyberinfrastructure: An Opening  

NASA Astrophysics Data System (ADS)

The Ocean Observatories Initiative is a long-term, NSF-funded program to provide 25-30 years of sustained ocean measurements to study climate variability, ocean circulation and ecosystem dynamics, air-sea exchange, seafloor processes, and plate-scale geodynamics. The OOI will enable powerful new scientific approaches for exploring the complexities of Earth-ocean-atmosphere interactions, thereby accelerating progress toward the goal of understanding, predicting, and managing our ocean environment. The OOI can foster new discoveries that, in turn, move research in unforeseen directions. The OOI Cyberinfrastructure will connect and coordinate the operations of OOI marine components and data processes, to meet the objectives of the oceanographic research and education communities. The CI will let all users easily interact with deployed resources, access collected data, and apply those data to their specific research and educational needs. The CI is a free and open product that adopts innovative and flexible strategies to bring the oceans to users, any time, any place, on any suitable device. The OOI CI is dedicated to "using the latest computing technologies to solve the interoperability problem among vast amounts of heterogeneous geospatial data from various sources." OOI CI's charge is to be transformative, and its technologies and goals are just that (see URL). The Cyberinfrastructure integrates state-of-the-art and best-practice approaches to provide fully interoperable access to the widest possible collection of geospatial data. From the system-of-systems model of the planned observatories and the ingestion of data, models, and services; to the configurable, automated workflows producing real-time products, data curation and quality management strategies are supported to the fullest possible extent. How do we build a system to efficiently support 750 core instruments across numerous platform types, add as-yet unknown instruments during the operations phase, and support any number of processes and external data in the system throughout its 25+ years of operation? What key strategies must be adopted, architectural approaches applied, and technologies integrated to provide complete discovery, access, and use of the system and its data? What defines the critical characteristics expected of the core system, the complete system, and the transformative system? And how can this system be leveraged by multiple science users, programs, and organizations beyond its initial target functionality? We will present the CI team's best responses to these questions. The project is completing Release 2, two-thirds of the way to a fully public release, and halfway to the final system. The engagement of OOI marine operations and marine science teams prepares us to support marine operations, and the software will be applied to "real operations" very soon. Most of the fundamental marine and operational scenarios are in place at a basic level, and the capabilities have been laid out for a full suite of mature operations and science activities. From these beginnings, we offer technical, social, and strategic perspectives on the challenges and solutions in geoinformatics data systems, and ask "Where to from here?" Funding for OOI is provided by the National Science Foundation through a Cooperative Agreement with the Consortium for Ocean Leadership, which in turn funds the CI project.

Open Geodata Initiative for Romania  

NASA Astrophysics Data System (ADS)

The concept of open data access is a very important topic nowadays. The concept assumes that all data collected or generated by public sector bodies (excepting personal data and data protected under existing privacy protection or accessibility rules) is made publicly accessible in commonly-used, machine-readable formats and can be re-used for any purpose, commercial or non-commercial. Governmental agencies are considered to be the most significant data owners and providers in modern societies. The sheer volume and wealth of this data makes apparent the potential benefits of reusing, combining, and processing governmental data. Even though metadata (information about the data) is sometimes published, administrations typically express reluctance to making their data available, for various reasons, cultural, political, legal, institutional and technical. The governmental spatial information (also called geospatial data, georeferenced data or geodata) producers in Romania are no exception -with the additional situation that even metadata is not usually available. Starting from 2013 a joint program between a Swiss partner (The Swiss Federal Institute of Technology ETH- Zurich - Institute of Cartography and Geoinformation) and a Romanian partner (Technical University of Civil Engineering - UTCB) is developed in order to establish a new approach on the open geodata topic. The main objective of the project GEOIDEA.RO (GEodata Openness Initiative for Development and Economic Advancement in ROmania) is to improve the scientific basis for open geodata model adoption in Romania. Is our believe that publishing government geodata in Romania over the Internet,under an open license and in a reusable format can strengthen citizen engagement and yield new innovative businesses, bringing substantial social and economic gains.

Laparoscopic Versus Open Colorectal Surgery  

PubMed Central

Summary Background Data: Studies comparing the costs of colorectal resection by laparoscopic (LPS) and open approaches are small sized or not randomized. The main purpose of this study is to compare the hospital costs of LPS and open colorectal surgery in a large series of randomized patients. Methods: A total of 517 patients with colorectal disease were randomly assigned to LPS (n = 258) or open (n = 259) resection. The following costs were calculated: surgical instruments, operative room (OR) occupation, routine care, postoperative morbidity, and length of hospital stay (LOS). Follow-up for postoperative morbidity was carried out for 30 days after hospital discharge. Results: Operative time was 37 minutes longer in the LPS group. Overall morbidity rate was 18.2% (47 of 258) in the LPS versus 34.7% (90 of 259) in the open group (P = 0.0005). The mean LOS was 9.9 (2.6) days in the LPS group and 12.4 (3.9) days in the open group (P < 0.0001). The additional OR charge in the LPS group was €1171 per patient randomized (€864 due to surgical instruments and €307 due to longer time). The saving in the LPS group was €1046 per patient randomized (€401 due to shorter LOS and €645 due to the lower cost of postoperative complications). The net balance resulted in €125 extra cost per patient allocated to the LPS group. Conclusions: The present cost-benefit analysis showed a slight additional cost in the LPS group. The better postoperative short-term outcome in patients receiving LPS had a key role to nearly balance the operative room charges due to laparoscopy. PMID:16327499

Open Source, Open Standards, and Health Care Information Systems

Recognition of the improvements in patient safety, quality of patient care, and efficiency that health care information systems have the potential to bring has led to significant investment. Globally the sale of health care information systems now represents a multibillion dollar industry. As policy makers, health care professionals, and patients, we have a responsibility to maximize the return on this investment. To this end we analyze alternative licensing and software development models, as well as the role of standards. We describe how licensing affects development. We argue for the superiority of open source licensing to promote safer, more effective health care information systems. We claim that open source licensing in health care information systems is essential to rational procurement strategy. PMID:21447469

Open Source and Open Access Resources for Quantum Physics Education  

NSDL National Science Digital Library

Quantum mechanics is both a topic of great importance to modern science, engineering, and technology, and a topic with many inherent barriers to learning and understanding. Computational resources are vital tools for developing deep conceptual understanding of quantum systems for students new to the subject. This article outlines two projects that are taking an open source/open access approach to create and share teaching and learning resources for quantum physics. The Open Source Physics project provides program libraries, programming tools, example simulations, and pedagogical resources for instructors wishing to give a rich experience to their students. These simulations and student activities are, in turn, being integrated into a world-wide collection of teaching and learning resources available through the Quantum Exchange, a part of the ComPADRE Portal to the National Science Digital Library. Both of these projects use technologies that encourage community development and collaboration. Using these tools, faculty can create learning experiences, share and discuss their content with others, and combine resources in new ways. Examples of the available content and tools are given, along with an introduction to accessing and using these resources.

The Commercial Open Source Business Model  

NASA Astrophysics Data System (ADS)

Commercial open source software projects are open source software projects that are owned by a single firm that derives a direct and significant revenue stream from the software. Commercial open source at first glance represents an economic paradox: How can a firm earn money if it is making its product available for free as open source? This paper presents the core properties of com mercial open source business models and discusses how they work. Using a commercial open source approach, firms can get to market faster with a superior product at lower cost than possible for traditional competitors. The paper shows how these benefits accrue from an engaged and self-supporting user community. Lacking any prior comprehensive reference, this paper is based on an analysis of public statements by practitioners of commercial open source. It forges the various anecdotes into a coherent description of revenue generation strategies and relevant business functions.

Morphology of Galactic Open Clusters  

E-print Network

We analyzed the shapes of Galactic open clusters by the star counting technique with the 2MASS star catalog database. Morphological parameters such as the ellipticity and size have been derived via stellar density distribution, weighed by clustering probability. We find that most star clusters are elongated, even for the youngest star clusters of a few million years old, which are located near to the Galactic disk. The shapes of young star clusters must reflect the conditions in the parental molecular clouds and during the cluster formation process. As an open cluster ages, stellar dynamics cause the inner part of the cluster to circularize, but the overall radius gets larger and the stellar density becomes sparser. We discuss how internal relaxation process competes with Galactic external perturbation during cluster evolution.

Increased security through open source  

E-print Network

In this paper we discuss the impact of open source on both the security and transparency of a software system. We focus on the more technical aspects of this issue, combining and extending arguments developed over the years. We stress that our discussion of the problem only applies to software for general purpose computing systems. For embedded systems, where the software usually cannot easily be patched or upgraded, different considerations may apply.

Open-Coil Retraction Spring  

PubMed Central

Sliding mechanic has become a popular method for space closure with developments in preadjusted edgewise appliance. Furthermore, various space closing auxiliaries have been developed and evaluated extensively for their clinical efficiency. Their effectiveness enhanced with optimum force magnitude and low-load deflection rate (LDR)/force decay. With the advent of NiTi springs in orthodontics, LDRs have been markedly reduced. For use of NiTi, clinician has to depend upon prefabricated closed coil springs. “Open Coil Retraction Spring (OCRS)” is developed utilizing NiTi open-coil spring for orthodontic space closure. This paper describes fabrication and clinical application of OCRS which have number of advantages. It sustains low LDR with optimum force magnitude. Its design is adjustable for desired length and force level. It is fail-safe for both activation and deactivation (i.e., it cannot be over activated, and decompression limit of open coil is also controlled by the operator, resp.). A possibility to offset the OCRS away from mucosa helps to reduce its soft-tissue impingement. PMID:22567437

OPENING ANGLES OF COLLAPSAR JETS  

SciTech Connect

We investigate the jet propagation and breakout from the stellar progenitor for gamma-ray burst (GRB) collapsars by performing two-dimensional relativistic hydrodynamic simulations and analytical modeling. We find that the jet opening angle is given by ?{sub j} ? 1/5?{sub 0} and infer the initial Lorentz factor of the jet at the central engine, ?{sub 0}, is a few for existing observations of ?{sub j}. The jet keeps the Lorentz factor low inside the star by converging cylindrically via collimation shocks under the cocoon pressure and accelerates at jet breakout before the free expansion to a hollow-cone structure. In this new picture, the GRB duration is determined by the sound crossing time of the cocoon, after which the opening angle widens, reducing the apparent luminosity. Some bursts violating the maximum opening angle ?{sub j,{sub max}} ? 1/5 ? 12° imply the existence of a baryon-rich sheath or a long-acting jet. We can explain the slopes in both Amati and Yonetoku spectral relations using an off-centered photosphere model, if we make only one assumption that the total jet luminosity is proportional to the initial Lorentz factor of the jet. We also numerically calibrate the pre-breakout model (Bromberg et al.) for later use.

Opening Angles of Collapsar Jets

We investigate the jet propagation and breakout from the stellar progenitor for gamma-ray burst (GRB) collapsars by performing two-dimensional relativistic hydrodynamic simulations and analytical modeling. We find that the jet opening angle is given by ? j ~ 1/5?0 and infer the initial Lorentz factor of the jet at the central engine, ?0, is a few for existing observations of ? j . The jet keeps the Lorentz factor low inside the star by converging cylindrically via collimation shocks under the cocoon pressure and accelerates at jet breakout before the free expansion to a hollow-cone structure. In this new picture, the GRB duration is determined by the sound crossing time of the cocoon, after which the opening angle widens, reducing the apparent luminosity.

Inflation on an Open Racetrack  

SciTech Connect

We present a variant of warped D-brane inflation by incorporating multiple sets of holomorphically - embedded D7-branes involved in moduli stabilization with extent into a warped throat. The resultant D3-brane motion depends on the D7-brane configuration and the relative position of the D3-brane in these backgrounds. The non-perturbative moduli stabilization superpotential takes the racetrack form, but the additional D3-brane open string moduli dependence provides more flexibilities in model building. For concreteness, we consider D3-brane motion in the warped deformed conifold with the presence of multiple D7-branes, and derive the scalar potential valid for the entire throat. By explicit tuning of the microphysical parameters, we obtain inflationary trajectories near an inflection point for various D7-brane configurations. Moreover, the open racetrack potential admits approximate Minkowski vacua before uplifting. We demonstrate with a concrete D-brane inflation model where the Hubble scale during inflation can exceed the gravitino mass. Finally, the multiple sets of D7-branes present in this open racetrack setup also provides a mechanism to stabilize the D3-brane to metastable vacua in the intermediate region of the warped throat.

Quantum Entanglement in Open Systems  

SciTech Connect

In the framework of the theory of open systems based on completely positive quantum dynamical semigroups, the master equation for two independent harmonic oscillators interacting with an environment is solved in the asymptotic long-time regime. Using the Peres-Simon necessary and sufficient condition for separability of two-mode Gaussian states, we show that the two non-interacting systems become asymptotically entangled for certain environments, so that in the long-time regime they manifest non-local quantum correlations. We calculate also the logarithmic negativity characterizing the degree of entanglement of the asymptotic state.

FLOSS projects are organized and developed in a fundamentally different way than CSS projects. FLOSS projects simply do not develop code as CSS projects do.

Macroeconomics in an open economy.

The customary treatment of national economies as closed and self-contained must be substantially modified to allow for those economies that typically trade goods, services, and securities with other countries in increasing volume. Open economy macroeconomics is essential to understanding the major events of the U.S. economy over the past half dozen years. Both the sharp rise in the dollar and the unprecedentedly large U.S. trade deficit are linked to the U.S. budget deficit, as is the drop in the rate of inflation. PMID:17756868

Open questions in classical gravity  

SciTech Connect

In this work, the authors discuss some outstanding open questions regarding the validity and uniqueness of the standard second-order Newton-Einstein classical gravitational theory. On the observational side the authors discuss the degree to which the realm of validity of Newton's law of gravity can actually be extended to distances much larger than the solar system distance scales on which the law was originally established. On the theoretical side the authors identify some commonly accepted (but actually still open to question) assumptions which go into the formulation of the standard second-order Einstein theory in the first place. In particular, it is shown that while the familiar second-order Poisson gravitational equation (and accordingly its second-order covariant Einstein generalization) may be sufficient to yield Newton's law of gravity they are not in fact necessary. The standard theory thus still awaits the identification of some principle which would then make it necessary too. It is shown that current observational information does not exclusively mandate the standard theory, and that the conformal invariant fourth-order theory of gravity considered recently by Mannheim and Kazanas is also able to meet the constraints of data, and in fact to do so without the need for any so far unobserved nonluminous or dark matter. 37 refs., 7 figs.

Java based open architecture controller  

SciTech Connect

At Lawrence Livermore National Laboratory (LLNL) the authors have been developing an open architecture machine tool controller. This work has been patterned after the General Motors (GM) led Open Modular Architecture Controller (OMAC) work, where they have been involved since its inception. The OMAC work has centered on creating sets of implementation neutral application programming interfaces (APIs) for machine control software components. In the work at LLNL, they were among the early adopters of the Java programming language. As an application programming language, it is particularly well suited for component software development. The language contains many features, which along with a well-defined implementation API (such as the OMAC APIs) allows third party binary files to be integrated into a working system. Because of its interpreted nature, Java allows rapid integration testing of components. However, for real-time systems development, the Java programming language presents many drawbacks. For instance, lack of well defined scheduling semantics and threading behavior can present many unwanted challenges. Also, the interpreted nature of the standard Java Virtual Machine (JVM) presents an immediate performance hit. Various real-time Java vendors are currently addressing some of these drawbacks. The various pluses and minuses of using the Java programming language and environment, with regard to a component-based controller, will be outlined.

Plasma opening switch conduction scaling  

SciTech Connect

Plasma opening switch (POS) experiments performed on the Hawk generator [Commisso {ital et} {ital al}., Phys. Fluids B {bold 4}, 2368 (1992)] (750 kA, 1.2 {mu}s) determine the dependence of the conduction current and conduction time on plasma density, electrode dimensions, and current rise rate. The experiments indicate that for a range of parameters, conduction is controlled by magnetohydrodynamic (MHD) distortion of the plasma, resulting in a low density region where opening can occur, possibly by erosion. The MHD distortion corresponds to an axial translation of the plasma center-of-mass by half the initial plasma length, leading to a simple scaling relation between the conduction current and time, and the injected plasma density and POS electrode dimensions that is applicable to a large number of POS experiments. For smaller currents and conduction times, the Hawk data suggest a non-MHD conduction limit that may correspond to electromagnetohydrodynamic (EMH) field penetration through the POS plasma. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.

Effects of artificial openings of intermittently opening estuaries on macroinvertebrate assemblages of the entrance barrier  

NASA Astrophysics Data System (ADS)

Intermittently opening estuaries are artificially opened to manage flood risk, water quality, recreational amenity, and fisheries; however, the ecological impacts of this management technique are incompletely understood. During 2001 and 2004, this study assessed the impacts of artificial openings on the macroinvertebrates of entrance barriers of intermittently opening estuaries in New South Wales (Australia). In 2001 macroinvertebrates were sampled once before artificial opening and 9 and 25 d after re-formation of the entrance barrier. A multiple before-after-control-impact analysis found that, although entrance barriers were destroyed by the artificial openings and then re-formed naturally by wave action, significant interactions for taxonomic richness, density of the amphipod Paracalliope australis (Gammaridae) and density of the gastropod mollusc Aschoris victoriae (Hydrobiidae) meant that the effects of this disturbance could not be distinguished from the natural variations that occurred in unopened estuaries. Multivariate analyses found that assemblages at both opened and unopened estuaries changed from before to after the openings, and the magnitude of the dissimilarity between times varied between estuaries. In 2004, macroinvertebrates were sampled on three randomly selected days within each of three periods (before, 3 d and 42 d after) at one opened and three unopened estuaries. Asymmetrical analysis of this modified before-after-control-impact study found that the change in taxonomic richness at the opened estuary from before to after opening did not differ from temporal changes that occurred in unopened estuaries. Short-term variation (i.e. between days) in total density of macroinvertebrates and density of P. australis in the re-formed entrance barrier of the opened estuary also did not differ from the variation in the control estuaries. Additionally, assemblage structure was not significantly changed by the opening and assemblages at two control estuaries were also unchanged over the same time. Individual taxa and assemblages of macroinvertebrates in entrance barriers of these intermittently open estuarine systems appear to be resilient to the habitat disturbance caused by artificial openings.

Defining an Open Source Strategy for NASA  

NASA Astrophysics Data System (ADS)

Over the course of the past year, we have worked to help frame a strategy for NASA and open source software. This includes defining information processes to understand open source licensing, attribution, commerciality, redistribution, communities, architectures, and interactions within the agency. Specifically we held a training session at the NASA Earth Science Data Systems Working Group meeting in Open Source software as it relates to the NASA Earth Science data systems enterprise, including EOSDIS, the Distributed Active Archive Centers (DAACs), ACCESS proposals, and the MEASURES communities, and efforts to understand how open source software can be both consumed and produced within that ecosystem. In addition, we presented at the 1st NASA Open Source Summit (OSS) and helped to define an agency-level strategy, a set of recommendations and paths forward for how to identify healthy open source communities, how to deal with issues such as contributions originating from other agencies, and how to search out talent with the right skills to develop software for NASA in the modern age. This talk will review our current recommendations for open source at NASA, and will cover the set of thirteen recommendations output from the NASA Open Source Summit and discuss some of their implications for the agency.

Measured opening characteristics of an electromagnetically opened diaphragm for the Langley expansion tunnel  

NASA Technical Reports Server (NTRS)

Results from an experimental study of the opening characteristics of an electromagnetically opened, 15.24 cm diameter diaphragm are presented. This diaphragm consists of a polyester film bonded to a preformed wire and is opened by passing a current pulse (capacitor discharge) through the wire. The diaphragm separates the acceleration section of the expansion tunnel from the nozzle so that the nozzle may be at a lower pressure than the acceleration section prior to a test. Opening times and cleanness of the opened area were examined for dependence on diaphragm thickness, on wire diameter, on technique of bonding the wire to the diaphragm, and on voltage and energy level of the energy source. Time histories of the pitot pressure measured at the expansion-tunnel nozzle entrance location are presented for (1) no diaphragm, (2) a flow-opened diaphragm, and (3) an electromagnetically opened diaphragm.

The ECMWF OpenIFS model  

NASA Astrophysics Data System (ADS)

The ECMWF OpenIFS project started in December 2011 and has the overall aim of providing a version of the IFS model forecast system for research and education at external institutions. The OpenIFS model is a reduced version of IFS that includes all the forecast capability but without any data assimilation. Improvements to the code structure and installation/compilation process have been made for use by research groups on their own computer systems. Dedicated OpenIFS support is provided at ECMWF. In this presentation we describe the objectives of the OpenIFS project, with more details on the capability of the model. The first OpenIFS users were the Department of Meteorology (MISU), Stockholm University in November/December 2012 as part of their MSc course. By way of example of the use of the model, we present results from the model integrations carried out based on the Lothar storm over Europe in December 1999.

Forward Field Computation with OpenMEEG  

PubMed Central

To recover the sources giving rise to electro- and magnetoencephalography in individual measurements, realistic physiological modeling is required, and accurate numerical solutions must be computed. We present OpenMEEG, which solves the electromagnetic forward problem in the quasistatic regime, for head models with piecewise constant conductivity. The core of OpenMEEG consists of the symmetric Boundary Element Method, which is based on an extended Green Representation theorem. OpenMEEG is able to provide lead fields for four different electromagnetic forward problems: Electroencephalography (EEG), Magnetoencephalography (MEG), Electrical Impedance Tomography (EIT), and intracranial electric potentials (IPs). OpenMEEG is open source and multiplatform. It can be used from Python and Matlab in conjunction with toolboxes that solve the inverse problem; its integration within FieldTrip is operational since release 2.0. PMID:21437231

[Open access :an opportunity for biomedical research].  

PubMed

Open access within the scientific community depends on the scientific context and the practices of the field. In the biomedical domain, the communication of research results is characterised by the importance of the peer reviewing process, the existence of a hierarchy among journals and the transfer of copyright to the editor. Biomedical publishing has become a lucrative market and the growth of electronic journals has not helped lower the costs. Indeed, it is difficult for today's public institutions to gain access to all the scientific literature. Open access is thus imperative, as demonstrated through the positions taken by a growing number of research funding bodies, the development of open access journals and efforts made in promoting open archives. This article describes the setting up of an Inserm portal for publication in the context of the French national protocol for open-access self-archiving and in an international context. PMID:18789227

Monte-Carlo Opening Books for Amazons  

NASA Astrophysics Data System (ADS)

Automatically creating opening books is a natural step towards the building of strong game-playing programs, especially when there is little available knowledge about the game. However, while recent popular Monte-Carlo Tree-Search programs showed strong results for various games, we show here that programs based on such methods cannot efficiently use opening books created using algorithms based on minimax. To overcome this issue, we propose to use an MCTS-based technique, Meta-MCTS, to create such opening books. This method, while requiring some tuning to arrive at the best opening book possible, shows promising results to create an opening book for the game of the Amazons, even if this is at the cost of removing its Monte-Carlo part.

Achieving open access to conservation science.  

PubMed

Conservation science is a crisis discipline in which the results of scientific enquiry must be made available quickly to those implementing management. We assessed the extent to which scientific research published since the year 2000 in 20 conservation science journals is publicly available. Of the 19,207 papers published, 1,667 (8.68%) are freely downloadable from an official repository. Moreover, only 938 papers (4.88%) meet the standard definition of open access in which material can be freely reused providing attribution to the authors is given. This compares poorly with a comparable set of 20 evolutionary biology journals, where 31.93% of papers are freely downloadable and 7.49% are open access. Seventeen of the 20 conservation journals offer an open access option, but fewer than 5% of the papers are available through open access. The cost of accessing the full body of conservation science runs into tens of thousands of dollars per year for institutional subscribers, and many conservation practitioners cannot access pay-per-view science through their workplace. However, important initiatives such as Research4Life are making science available to organizations in developing countries. We urge authors of conservation science to pay for open access on a per-article basis or to choose publication in open access journals, taking care to ensure the license allows reuse for any purpose providing attribution is given. Currently, it would cost $51 million to make all conservation science published since 2000 freely available by paying the open access fees currently levied to authors. Publishers of conservation journals might consider more cost effective models for open access and conservation-oriented organizations running journals could consider a broader range of options for open access to nonmembers such as sponsorship of open access via membership fees.

Summing Planar Bosonic Open Strings  

SciTech Connect

In earlier work, planar graphs of massless {phi}{sup 3} theory were summed with the help of the light cone world sheet picture and the mean field approximation. In the present article, the same methods are applied to the problem of summing planar bosonic open strings. They find that in the ground state of the system, string boundaries form a condensate on the world sheet, and a new string emerges from this summation. Its slope is always greater than the initial slope, and it remains non-zero even when the initial slope is set equal to zero. If they assume the initial string tends to a field a theory in the zero slope limit, this result provides evidence for string formation in field theory.

Combined endovascular and open revascularization.  

PubMed

The last decade has borne witness to a transformation in the care of patients with vascular disease. There has been a rapid transition towards minimally invasive techniques as interventionalists obtain increasingly advanced catheter-based skills and access to newer and more sophisticated devices. Patients who are not candidates for completely percutaneous revascularization, or those felt to be at prohibitive risk for traditional surgical reconstruction, may benefit from hybrid therapy, a combination of open surgery and endovascular repair that offers patients the opportunity for complete revascularization with decreased morbidity and mortality. This review examines applications of hybrid procedures for treating patients with disabling claudication and limb-threatening ischemia, aortic arch disease, thoracoabdominal aneurysms, extra-cranial carotid disease, and coronary artery disease.

Open Architecture SDR for Space  

NASA Technical Reports Server (NTRS)

This paper describes an open-architecture SDR (software defined radio) infrastructure that is suitable for space-based operations (Space-SDR). SDR technologies will endow space and planetary exploration systems with dramatically increased capability, reduced power consumption, and significantly less mass than conventional systems, at costs reduced by vigorous competition, hardware commonality, dense integration, reduced obsolescence, interoperability, and software re-use. Significant progress has been recorded on developments like the Joint Tactical Radio System (JSTRS) Software Communication Architecture (SCA), which is oriented toward reconfigurable radios for defense forces operating in multiple theaters of engagement. The JTRS-SCA presents a consistent software interface for waveform development, and facilitates interoperability, waveform portability, software re-use, and technology evolution.

Toxic emissions from open burning.  

PubMed

This review compiled the data from recent actual and simulation studies on toxic emissions from open burning and categorized into sources, broadly as biomass and anthropogenic fuels. Emission factors, in mass of pollutant per mass of material being burned, and actual concentrations, in mass of pollutant per unit volume have been compared based on source classifications. In addition to gaseous emissions, this review presents the updated data on emissions to air in the form of particulate matter, and emissions to soil and water environment. Data from forest fires, accidental fires such as vehicle fires, house fires, and unintentional landfill fires are included in this review as well as combustion involving traditional and recreational activities.

An open letter was published by Latin American and Caribbean women during the Special Session of the UN General Assembly on the International Conference on Population and Development. The letter generally focused on the Church¿s stand on women's reproductive rights. In particular, it questioned the Church on the following aspects of reproductive health, which include: 1) maternal death related to lack of access to reproductive health care; 2) Vatican representatives insisting that only parents can supervise their children education and health, which also lead to many cases of sexual abuse and incest; 3) women's sexual inequality and daily violence; 4) the Vatican delegation blocking the advances of contraception, sexual education, and HIV prevention; 5) problems of migrants and allocation of resources; and 6) the Church failing to recognize the capacity of young people to make decisions based on their own conscience.

Bandgap Opening by Patterning Graphene  

PubMed Central

Owing to its remarkable electronic and transport properties, graphene has great potential of replacing silicon for next-generation electronics and optoelectronics; but its zero bandgap associated with Dirac fermions prevents such applications. Among numerous attempts to create semiconducting graphene, periodic patterning using defects, passivation, doping, nanoscale perforation, etc., is particularly promising and has been realized experimentally. However, despite extensive theoretical investigations, the precise role of periodic modulations on electronic structures of graphene remains elusive. Here we employ both the tight-binding modeling and first-principles electronic structure calculations to show that the appearance of bandgap in patterned graphene has a geometric symmetry origin. Thus the analytic rule of gap-opening by patterning graphene is derived, which indicates that if a modified graphene is a semiconductor, its two corresponding carbon nanotubes, whose chiral vectors equal graphene's supercell lattice vectors, are both semimetals.

Variational Functions in Open Systems  

NASA Astrophysics Data System (ADS)

This paper looks for an entropy-like quantity having a monotonic time development. In the case of spontaneous emission, the final state usually consists of a single ground state assigning zero to the ordinary expressions for entropy. Thus entropy ceases to be a monotonic measure of the direction of time. The point is illustrated by a simple test case consisting of three levels coupled by spontaneous emission. It is shown how this case allows the definition of a monotonic function. Using the theory of non-Hermitian operators, the paper shows how such a function may be constructed in the general case, and it explores the main consequences of the expressions suggested. The generalization of the entropy concept is found to relate to time-reversal properties of the dynamics. The paper concludes by discussing open questions and possible further explorations.

Open Standards for Emergency Mangement  

NASA Astrophysics Data System (ADS)

The mission of the OASIS (Organization for the Advancement of Structured Information Standards) Emergency Management Technical Committee (EM-TC) is to create incident and emergency-related standards for data interoperability. The TC welcomes participation from members of the emergency management community, developers and implementers, and members of the public concerned with disaster management and response. Since the foundation of the EM-TC in 2003, there have been several Standards developed to support this mission. The first and most widely accepted has been the Common Alerting Protocol (CAP). CAP has been adopted worldwide and is also ITU Recommendation 1303. The EM-TC has continued in the development of content data standards to support the emergency management mission. This suite of standards is referred to as the Emergency Data Exchange Language (EDXL) family of standards. The EDXL suite of standards are developed starting with a defined requirement from the response community. The requirements are vetted through a working group process, reviewed by the development community to determine whether the concepts once "standardized" will result in software that will be developed then provided with comments to the OASIS EM-TC for defining the standard. The OASIS process includes an open public review period where all comments are accepted and publically adjudicated. The EDXL-Distribution Element (DE), EDXL-Resource Management (RM), EDXL-Hospital Availability eXchange (HAVE) are all now ratified Standards. The EDXL-Situation Reporting (SitRep) Standard is in final review and the EXDL-Tracking of Emergency Patients (TEP) is in development. This presentation will briefly present each of the OASIS EM-TC Standards as well as the process for their development and review. Information will be provided about how to participate in the process as well as where open source code can be found to get started developing systems of systems using the EDXL Standards.

DISCONNECTING OPEN SOLAR MAGNETIC FLUX  

SciTech Connect

Disconnection of open magnetic flux by reconnection is required to balance the injection of open flux by coronal mass ejections and other eruptive events. Making use of recent advances in heliospheric background subtraction, we have imaged many abrupt disconnection events. These events produce dense plasma clouds whose distinctive shape can now be traced from the corona across the inner solar system via heliospheric imaging. The morphology of each initial event is characteristic of magnetic reconnection across a current sheet, and the newly disconnected flux takes the form of a 'U-'shaped loop that moves outward, accreting coronal and solar wind material. We analyzed one such event on 2008 December 18 as it formed and accelerated at 20 m s{sup -2} to 320 km s{sup -1}, thereafter expanding self-similarly until it exited our field of view 1.2 AU from the Sun. From acceleration and photometric mass estimates we derive the coronal magnetic field strength to be 8 {mu}T, 6 R{sub Sun} above the photosphere, and the entrained flux to be 1.6 Multiplication-Sign 10{sup 11} Wb (1.6 Multiplication-Sign 10{sup 19} Mx). We model the feature's propagation by balancing inferred magnetic tension force against accretion drag. This model is consistent with the feature's behavior and accepted solar wind parameters. By counting events over a 36 day window, we estimate a global event rate of 1 day{sup -1} and a global solar minimum unsigned flux disconnection rate of 6 Multiplication-Sign 10{sup 13} Wb yr{sup -1} (6 Multiplication-Sign 10{sup 21} Mx yr{sup -1}) by this mechanism. That rate corresponds to {approx} - 0.2 nT yr{sup -1} change in the radial heliospheric field at 1 AU, indicating that the mechanism is important to the heliospheric flux balance.

The open quantum Brownian motions  

NASA Astrophysics Data System (ADS)

Using quantum parallelism on random walks as the original seed, we introduce new quantum stochastic processes, the open quantum Brownian motions. They describe the behaviors of quantum walkers—with internal degrees of freedom which serve as random gyroscopes—interacting with a series of probes which serve as quantum coins. These processes may also be viewed as the scaling limit of open quantum random walks and we develop this approach along three different lines: the quantum trajectory, the quantum dynamical map and the quantum stochastic differential equation. We also present a study of the simplest case, with a two level system as an internal gyroscope, illustrating the interplay between the ballistic and diffusive behaviors at work in these processes. Notation H_z : orbital (walker) Hilbert space, {C}^{{Z}} in the discrete, L^2({R}) in the continuum H_c : internal spin (or gyroscope) Hilbert space H_sys=H_z\\otimesH_c : system Hilbert space H_p : probe (or quantum coin) Hilbert space, H_p={C}^2 \\rho^tot_t : density matrix for the total system (walker + internal spin + quantum coins) \\bar \\rho_t : reduced density matrix on H_sys : \\bar\\rho_t=\\int dxdy\\, \\bar\\rho_t(x,y)\\otimes | x \\rangle _z\\langle y | \\hat \\rho_t : system density matrix in a quantum trajectory: \\hat\\rho_t=\\int dxdy\\, \\hat\\rho_t(x,y)\\otimes | x \\rangle _z\\langle y | .

Trapping light in open plasmonic nanostructures  

NASA Astrophysics Data System (ADS)

In open resonators the energy associated with a localized photonic excitation is lost in the form of a radiated wave, in the same manner that a classical charged particle in a curved orbit loses energy in the form of electromagnetic radiation. As a consequence, photonic modes in conventional spatially bounded open resonators have finite decay times. Here, we theoretically show that, surprisingly, in the limit of vanishing material loss, plasmons give the opportunity to have light localization in open spatially bounded systems with infinitely large lifetimes.

OPENING ADDRESS: Heterostructures in Semiconductors  

NASA Astrophysics Data System (ADS)

Good morning, Gentlemen! On behalf of the Nobel Foundation, I should like to welcome you to the Nobel Symposium on "Heterostructures in Semiconductors". It gives me great pleasure to see so many colleagues and old friends from all over the world in the audience and, in particular, to bid welcome to our Nobel laureates, Prof. Esaki and Prof. von Klitzing. In front of a different audience I would now commend the scientific and technological importance of heterostructures in semiconductors and emphatically emphasise that heterostructures, as an important contribution to microelectronics and, hence, information technology, have changed societies all over the world. I would also mention that information technology is one of the most important global key industries which covers a wide field of important areas each of which bears its own character. Ever since the invention of the transistor, we have witnessed a fantastic growth in semiconductor technology, leading to more complex functions and higher densities of devices. This development would hardly be possible without an increasing understanding of semiconductor materials and new concepts in material growth techniques which allow the fabrication of previously unknown semiconductor structures. But here and today I will not do it because it would mean to carry coals to Newcastle. I will therefore not remind you that heterostructures were already suggested and discussed in detail a long time before proper technologies were available for the fabrication of such structures. Now, heterostructures are a foundation in science and part of our everyday life. Though this is certainly true, it is nevertheless fair to say that not all properties of heterostructures are yet understood and that further technologies have to be developed before a still better understanding is obtained. The organisers therefore hope that this symposium will contribute not only to improving our understanding of heterostructures but also to opening new perspectives for future applications. We are most grateful that you agreed with the special format of the symposium which clearly does not follow conven- tional conferences. Allow me to call your special attention once again to two main differences: The presentations are not review papers praising already achieved break-throughs but introductions to a list of open questions and issues for which our understanding is still unsatisfactory. To give such presentations requires courage and scientific integrity. I would like to thank all speakers now already for their willingness to cope with such a difficult task. We have allocated at least 50 minutes for discussion after each presentation not only for discussing the paper as such but, if possible, to find answers to the open questions. If one or several participants in the audience during the discussion think they can contribute to improving our understanding of heterostructures, they are invited to write their ideas up and, if the referees agree, we are more than happy to publish these ideas in the proceedings. We admit that the program is rather demanding. For that reason, we plan to have a break on Thursday afternoon by first going to Denmark and touring the Hamlet castle of Kronborg. We then sail back to Sweden and will be hosted by the Krapperup castle where we will have a candle-light dinner and thereafter a baroque music concert featuring the Concerto Copenhagen. All participants, observers, and accompanying spouses are invited and we hope you will all enjoy the excur- sion. The local organising committee acknowledges with pleasure the financial and all other support received from the Nobel Foundation and the Nobel Institute of Physics as well as the initial initiative taken by the chairman of the Nobel Com- mittee for Physics, Prof. Nordling, who was the first to suggest this Nobel Symposium on "Heterostructures in Semicon- ductors". Special thanks also to the members of the program committee who have been of inestimable value in putting together the program and suggesting speakers and pote

Open Access to essential health care information.  

PubMed

Open Access publishing is a valuable resource for the synthesis and distribution of essential health care information. This article discusses the potential benefits of Open Access, specifically in terms of Low and Middle Income (LAMI) countries in which there is currently a lack of informed health care providers - mainly a consequence of poor availability to information. We propose that without copyright restrictions, Open Access facilitates distribution of the most relevant research and health care information. Furthermore, we suggest that the technology and infrastructure that has been put in place for Open Access could be used to publish download-able manuals, guides or basic handbooks created by healthcare providers in LAMI countries.

Randomized control of open quantum systems  

E-print Network

The problem of open-loop dynamical control of generic open quantum systems is addressed. In particular, I focus on the task of effectively switching off environmental couplings responsible for unwanted decoherence and dissipation effects. After revisiting the standard framework for dynamical decoupling via deterministic controls, I describe a different approach whereby the controller intentionally acquires a random component. An explicit error bound on worst-case performance of stochastic decoupling is presented.

Open cycle - OTEC turbine design  

NASA Astrophysics Data System (ADS)

The design of a low-pressure, open cycle ocean thermal energy conversion system (OTEC) is described. Near-surface ocean water at 80 F is allowed to expand in a one-half psi evaporator for passage through a turbine; cold water (40 F), pumped upward from a 3,000 ft depth, is used to recondense the steam. Plans for a 2.5-3 MWe prototype plant, as a proof-of-principle project for a 100 MWe plant, include seawater pumps driven off the generator shaft, potable water as a by-product of the condensor, ease of access for O and M, and an integrated, gear-driven deaerator system with reinjection into the warm seawater discharge. An inlet flow of 3,000,000 cu ft/sec, a single stage vertical turbine with 40 ft fiber reinforced composite blades, 200 rpm operation on a 65 ft diameter disk, and an overall efficiency of 3% are features of the 100 MWe plant. A flowfield analysis, a velocity triangle analysis, and a structural dynamics analysis are outlined, along with materials applications and manufacturing process considerations in blade design. The 3MWe OTEC will be one-sixth the size of a 100MWe OTEC.

Studies of Degraded Smelt Spout Opening Tubes  

SciTech Connect

Co-extruded type 304L stainless steel/SA210 carbon steel tubes have been used on the floors and lower walls of many black liquor recovery boilers to address the wall thinning problem that had been an issue for boiler owners and operators. Use of these tubes greatly reduced the corrosion issue, but corrosion was still sometimes observed and cracking was discovered in some tubes, particularly those that are bent to form the openings for smelt spouts. Because cracks in the opening tubes were sometimes observed to extend a significant distance into the tube wall and because these cracks were found fairly frequently, tubes made from a number of alternate cladding materials were tried in place of the 304L clad opening tubes. This paper describes the results of examinations of spout opening tubes of the standard 304L/carbon steel and of several of the alternate materials that have been tried. In addition to the corrosion and cracking seen in the spout opening tubes, another issue associated with these tubes has been observed. Preferential corrosion of the cap welds is sometimes seen on butt welds attaching the spout opening tubes made with alternate cladding materials to the standard 304L/carbon steel co-extruded wall tubes. Some information on the observations of this corrosion is also included in this paper.

Open-pit equipment notebook  

SciTech Connect

Beds of consolidated material need to be drilled and blasted before successful excavation. In open-pit mining it is common to move fragmented material across to spoil piles by dragline, shovel, or bucketwheel excavator. One method recently introduced uses explosives to throw much of the overburden across the pit, thus reducing the amount of material needing rehandling. The increased cost of explosives must be balanced with the reduced cost of power needed by the prime excavator. The drill hole pattern and the use of high energy explosives require careful design. Making the choice between hydraulic excavators with a backhoe or front shovel, wheel loaders, and rope-operated shovels continues to be an interesting area of debate. While the rope-operated electric shovel is best for large output, smaller shovels are being replaced by hydraulic excavators for numerous reasons. One of the advantages of hydraulic excavators is that they weigh around half that of rope-operated shovels with the same size bucket. Another advantage is their mobility. They can move at a speed roughly twice that of a rope-operated shovel. Hydraulic excavators can successfully attack a solid face that needs blasting before being loaded by a wheel loader or rope-operated shovel. Neither the rope-operated shovel nor the wheel loader has the wrist-action of the hydraulic excavator. The backhoe's ability to dig below the level on which it is situated and to load trucks that are on the pit floor is important. Recently, many equipment manufacturers have introduced microprocessor-controlled systems for higher power and simpler operation. The choice between wheel loaders and hydraulic excavators should be based on site conditions.

Role of coronoidectomy in increasing mouth opening  

PubMed Central

Aim: To evaluate the effectiveness of coronoidectomy in advanced (stage III-IV) oral submucous fibrosis (OSMF) and temporomandibular joint (TMJ) ankylosis. Materials and Methods: Five patients clinically diagnosed as grade III/IV OSMF (group 1) and seven patients clinically and radiographically confirmed as TMJ ankylosis (group 2) underwent surgery entailing coronoidectomy in addition to conventional surgical procedures required in both the conditions followed by vigorous mouth opening exercises. The results were evaluated using the interincisal distance at maximum mouth opening as the objective outcome over a follow-up period of 2 months. Results: OSMF patients (group I) showed a mean preoperative interincisal opening of 14.40 mm which increased to 24.60 mm after conventional procedures and showed further increment to 35 and 44.80 mm after unilateral and bilateral coronoidectomy, respectively; which was statistically significant (P = 0.043). Follow-up of 2 months showed a gradual increase in mean mouth opening compared to baseline which was also found to be statistically significant (P = 0.043). In TMJ ankylosis patients (group II), preoperative mean mouth opening of 6.71 mm increased to 24.29 mm after conventional procedures, and further to 37.29 mm after unilateral coronoidectomy which was statistically significant (P = 0.018). On subsequent follow-up of 2 months, a gradual increase in mean mouth opening compared to baseline was observed which was statistically significant (P = 0.018). Conclusion: Coronoidectomy is an effective adjunct in increasing intraoperative and stabilizing postoperative mouth opening.

Defining and using open architecture levels  

NASA Astrophysics Data System (ADS)

Open architecture (OA) within military systems enables delivery of increased warfighter capabilities in a shorter time at a reduced cost.i In fact in today's standards-aware environment, solutions are often proposed to the government that include OA as one of its basics design tenets. Yet the ability to measure and assess OA in an objective manner, particularly at the subsystem/component level within a system, remains an elusive proposition. Furthermore, it is increasingly apparent that the establishment of an innovation ecosystem of an open business model that leverages thirdparty development requires more than just technical modifications that promote openness. This paper proposes a framework to migrate not only towards technical openness, but also towards enabling and facilitating an open business model, driven by third party development, for military systems. This framework was developed originally for the U.S. Navy Littoral and Mine Warfare community; however, the principles and approach may be applied elsewhere within the Navy and Department of Defense.

Development organizations and International Non-Governmental Organizations have been emphasizing the high potential of Free and Open Source Software for the Less Developed Countries. Cost reduction, less vendor dependency and increased potential for local capacity development have been their main arguments. In spite of its advantages, Free and Open Source Software is not widely adopted at the African continent. In this book the authors will explore the grounds on with these expectations are based. Where do they come from and is there evidence to support these expectations? Over the past years several projects have been initiated and some good results have been achieved, but at the same time many challenges were encountered. What lessons can be drawn from these experiences and do these experiences contain enough evidence to support the high expectations? Several projects and their achievements will be considered. In the final part of the book the future of Free and Open Source Software for Development will be explored. Special attention is given to the African continent since here challenges are highest. What is the role of Free and open Source Software for Development and how do we need to position and explore the potential? What are the threats? The book aims at professionals that are engaged in the design and implementation of ICT for Development (ICT4D) projects and want to improve their understanding of the role Free and Open Source Software can play.

OpenFLUID: an open-source software environment for modelling fluxes in landscapes  

NASA Astrophysics Data System (ADS)

Integrative landscape functioning has become a common concept in environmental management. Landscapes are complex systems where many processes interact in time and space. In agro-ecosystems, these processes are mainly physical processes, including hydrological-processes, biological processes and human activities. Modelling such systems requires an interdisciplinary approach, coupling models coming from different disciplines, developed by different teams. In order to support collaborative works, involving many models coupled in time and space for integrative simulations, an open software modelling platform is a relevant answer. OpenFLUID is an open source software platform for modelling landscape functioning, mainly focused on spatial fluxes. It provides an advanced object-oriented architecture allowing to i) couple models developed de novo or from existing source code, and which are dynamically plugged to the platform, ii) represent landscapes as hierarchical graphs, taking into account multi-scale, spatial heterogeneities and landscape objects connectivity, iii) run and explore simulations in many ways : using the OpenFLUID software interfaces for users (command line interface, graphical user interface), or using external applications such as GNU R through the provided ROpenFLUID package. OpenFLUID is developed in C++ and relies on open source libraries only (Boost, libXML2, GLib/GTK, OGR/GDAL, …). For modelers and developers, OpenFLUID provides a dedicated environment for model development, which is based on an open source toolchain, including the Eclipse editor, the GCC compiler and the CMake build system. OpenFLUID is distributed under the GPLv3 open source license, with a special exception allowing to plug existing models licensed under any license. It is clearly in the spirit of sharing knowledge and favouring collaboration in a community of modelers. OpenFLUID has been involved in many research applications, such as modelling of hydrological network transfer, diagnosis and prediction of water quality taking into account human activities, study of the effect of spatial organization on hydrological fluxes, modelling of surface-subsurface water exchanges, … At LISAH research unit, OpenFLUID is the supporting development platform of the MHYDAS model, which is a distributed model for agrosystems (Moussa et al., 2002, Hydrological Processes, 16, 393-412).

FOSE: a framework for open science evaluation.  

PubMed

Pre-publication peer review of scientific literature in its present state suffers from a lack of evaluation validity and transparency to the community. Inspired by social networks, we propose a framework for the open exchange of post-publication evaluation to complement the current system. We first formulate a number of necessary conditions that should be met by any design dedicated to perform open scientific evaluation. To introduce our framework, we provide a basic data standard and communication protocol. We argue for the superiority of a provider-independent framework, over a few isolated implementations, which allows the collection and analysis of open evaluation content across a wide range of diverse providers like scientific journals, research institutions, social networks, publishers websites, and more. Furthermore, we describe how its technical implementation can be achieved by using existing web standards and technology. Finally, we illustrate this with a set of examples and discuss further potential. PMID:22754522

Hydraulically controlled discrete sampling from open boreholes.  

PubMed

Groundwater sampling from open boreholes in fractured-rock aquifers is particularly challenging because of mixing and dilution of fluid within the borehole from multiple fractures. This note presents an alternative to traditional sampling in open boreholes with packer assemblies. The alternative system called ZONFLO (zonal flow) is based on hydraulic control of borehole flow conditions. Fluid from discrete fractures zones are hydraulically isolated allowing for the collection of representative samples. In rough-faced open boreholes and formations with less competent rock, hydraulic containment may offer an attractive alternative to physical containment with packers. Preliminary test results indicate a discrete zone can be effectively hydraulically isolated from other zones within a borehole for the purpose of groundwater sampling using this new method.

Advanced emergency openings for commercial aircraft  

NASA Technical Reports Server (NTRS)

Explosively actuated openings in composite panels are proposed to enhance passenger survivability within commercial aircraft by providing improvements in emergency openings, fuselage venting, and fuel dump. The concept is to embed a tiny, highly stable explosive cord in the periphery of a load-carrying composite panel; on initiation of the cord, the panel is fractured to create a well-defined opening. The panel would be installed in the sides of the fuselage for passenger egress, in the top of the fuselage for smoke venting, and in the bottoms of the fuel cells for fuel dump. Described are the concerns with the use of explosive systems, safety improvements, advantages, experimental results, and recommended approach to gain acceptance and develop this concept.

Wide-open and scanning ESM systems  

NASA Astrophysics Data System (ADS)

A comparison is conducted between open and scanning Electronic Warfare Support Measures (ESM) systems. Wide open ESM systems are generally known as high probability of intercept systems, while scanning systems have a higher sensitivity. The interception capability of the RF part of both types of systems is discussed. Two fundamentally different antenna types are currently employed in ESM systems, including the rotating beam type and the omnidirectional antenna. Antennas belonging to the rotating beam type can be divided into conventional rotating antennas and phased array antennas. The rotational antenna has a certain frequency-dependent gain due to its directivity. The omnidirectional antenna is mostly of the multibeam type. A number of separate antennas is employed to cover 360 deg in azimuth. Attention is given to narrow-band and broadband receivers, interception by the scanning system, and interception by the wide-open system.

Physicochemical insight into gap openings in graphene  

PubMed Central

Based on a newly developed size-dependent cohesive energy formula for two-dimensional materials, a unified theoretical model was established to illustrate the gap openings in disordered graphene flakes, involving quantum dots, nanoribbons and nanoporous sheets. It tells us that the openings are essentially dominated by the variation in cohesive energy of C atoms, associated to the edge physicochemical nature regarding the coordination imperfection or the chemical bonding. In contrast to those ideal flakes, consequently, the gaps can be opened monotonously for disordered flakes on changing their sizes, affected by the dimension, geometric shape and the edge saturation. Using the density functional theory, accordingly, the electronic structures of disordered flakes differ to the ideal case because of the edge disorder. Our theoretical predictions have been validated by available experimental results, and provide us a distinct way for the quantitative modulation of bandgap in graphene for nanoelectronics.

[The publishing industry against open access journals].  

PubMed

Open-access journal publishing has significantly grown in recent years. Restricted access publications have, in turn, increasing access costs as they benefit from a unique economic model in which relevant work and essential inputs are provided free of charge to vendors who have a captive market that has almost no competition. An additional issue typical of industries that work under the copyright regime is that the oligopoly market structure of the publishing industry which in turn further contributes to increase their products' prices. Mandatory open-access policies, as determined by the NIH, constitute a threat to this business model and are being challenged by the industry on several fronts, including the passage of legislation to undermine these initiatives. The purpose of this commentary article was to review key aspects of this confrontation and to suggest potential strategies for encouraging open-access publishing in Brazil. PMID:23380837

Open Hardware for CERN's accelerator control systems  

NASA Astrophysics Data System (ADS)

The accelerator control systems at CERN will be upgraded and many electronics modules such as analog and digital I/O, level converters and repeaters, serial links and timing modules are being redesigned. The new developments are based on the FPGA Mezzanine Card, PCI Express and VME64x standards while the Wishbone specification is used as a system on a chip bus. To attract partners, the projects are developed in an `Open' fashion. Within this Open Hardware project new ways of working with industry are being evaluated and it has been proven that industry can be involved at all stages, from design to production and support.

Open Access: From Myth to Paradox  

ScienceCinema

True open access to scientific publications not only gives readers the possibility to read articles without paying subscription, but also makes the material available for automated ingestion and harvesting by 3rd parties. Once articles and associated data become universally treatable as computable objects, openly available to 3rd party aggregators and value-added services, what new services can we expect, and how will they change the way that researchers interact with their scholarly communications infrastructure? I will discuss straightforward applications of existing ideas and services, including citation analysis, collaborative filtering, external database linkages, interoperability, and other forms of automated markup, and speculate on the sociology of the next generation of users.

Bulk deformations of open topological string theory  

E-print Network

We present a general method to construct bulk-deformed open topological string theories from Landau-Ginzburg models. To this end we obtain a weak version of deformation quantisation, and we show how this together with the technique of homological perturbation allows to explicitly compute all bulk-deformed open topological string amplitudes at tree-level before tadpole-cancellation. Our approach is based on a coherent treatment of the problem in terms of the fundamental A-infinity- and L-infinity-structures involved.

Effect of noise in open chaotic billiards  

E-print Network

We investigate the effect of white-noise perturbations on chaotic trajectories in open billiards. We focus on the temporal decay of the survival probability for generic mixed-phase-space billiards. The survival probability has a total of five different decay regimes that prevail for different intermediate times. We combine new calculations and recent results on noise perturbed Hamiltonian systems to characterize the origin of these regimes, and to compute how the parameters scale with noise intensity and billiard openness. Numerical simulations in the annular billiard support and illustrate our results.
