  1. Adaptation of a Control Center Development Environment for Industrial Process Control

    NASA Technical Reports Server (NTRS)

    Killough, Ronnie L.; Malik, James M.

    1994-01-01

    In the control center, raw telemetry data is received for storage, display, and analysis. This raw data must be combined and manipulated in various ways by mathematical computations to facilitate analysis, provide diversified fault detection mechanisms, and enhance display readability. A development tool called the Graphical Computation Builder (GCB) has been implemented which provides flight controllers with the capability to implement computations for use in the control center. The GCB provides a language that contains both general programming constructs and language elements specifically tailored for the control center environment. The GCB concept allows staff who are not skilled in computer programming to author and maintain computer programs. The GCB user is isolated from the details of external subsystem interfaces and has access to high-level functions such as matrix operators, trigonometric functions, and unit conversion macros. The GCB provides a high level of feedback during computation development that improves upon the often cryptic errors produced by computer language compilers. An equivalent need can be identified in the industrial data acquisition and process control domain: that of an integrated graphical development tool tailored to the application to hide the operating system, computer language, and data acquisition interface details. The GCB features a modular design which makes it suitable for technology transfer without significant rework. Control center-specific language elements can be replaced by elements specific to industrial process control.

    2002-01-01

    The ISS finally reached an operational state and exists for local and remote users. Onboard payload systems are managed by the Huntsville Operations Support Center (HOSC). Users access HOSC systems by internet protocols in support of daily operations, preflight simulation, and test. In support of this diverse user community, a modem security architecture has been implemented. The architecture has evolved over time from an isolated but open system to a system which supports local and remote access to the ISS over broad geographic regions. This has been accomplished through the use of an evolved security strategy, PKI, and custom design. Through this paper, descriptions of the migration process and the lessons learned are presented. This will include product decision criteria, rationale, and the use of commodity products in the end architecture. This paper will also stress the need for interoperability of various products and the effects of seemingly insignificant details.

    2010-01-01

    The technology of transmitting voice over data networks has been available for over 10 years. Mass market VoIP services for consumers to make and receive standard telephone calls over broadband Internet networks have grown in the last 5 years. While operational costs are less with VoIP implementations as opposed to time division multiplexing (TDM) based voice switches, is it still advantageous to convert a mission control center s voice system to this newer technology? Marshall Space Flight Center (MSFC) Huntsville Operations Support Center (HOSC) has converted its mission voice services to a commercial product that utilizes VoIP technology. Results from this testing, design, and installation have shown unique considerations that must be addressed before user operations. There are many factors to consider for a control center voice design. Technology advantages and disadvantages were investigated as they refer to cost. There were integration concerns which could lead to complex failure scenarios but simpler integration for the mission infrastructure. MSFC HOSC will benefit from this voice conversion with less product replacement cost, less operations cost and a more integrated mission services environment.

  11. The Electronic Documentation Project in the NASA mission control center environment

    Wang, Lui; Leigh, Albert

    1994-01-01

    NASA's space programs like many other technical programs of its magnitude is supported by a large volume of technical documents. These documents are not only diverse but also abundant. Management, maintenance, and retrieval of these documents is a challenging problem by itself; but, relating and cross-referencing this wealth of information when it is all on a medium of paper is an even greater challenge. The Electronic Documentation Project (EDP) is to provide an electronic system capable of developing, distributing and controlling changes for crew/ground controller procedures and related documents. There are two primary motives for the solution. The first motive is to reduce the cost of maintaining the current paper based method of operations by replacing paper documents with electronic information storage and retrieval. And, the other is to improve the efficiency and provide enhanced flexibility in document usage. Initially, the current paper based system will be faithfully reproduced in an electronic format to be used in the document viewing system. In addition, this metaphor will have hypertext extensions. Hypertext features support basic functions such as full text searches, key word searches, data retrieval, and traversal between nodes of information as well as speeding up the data access rate. They enable related but separate documents to have relationships, and allow the user to explore information naturally through non-linear link traversals. The basic operational requirements of the document viewing system are to: provide an electronic corollary to the current method of paper based document usage; supplement and ultimately replace paper-based documents; maintain focused toward control center operations such as Flight Data File, Flight Rules and Console Handbook viewing; and be available NASA wide.

    1994-01-01

    Today, any approach to the design of new space systems must take into consideration an important constraint, namely costs. This approach is our guideline for new missions and also applies to the ground segment, and particularly to the control center. CNES has carried out a study on a recent control center for application satellites in order to take advantage of the experience gained. This analysis, the purpose of which is to determine, a posteriori, the costs of architecture needs and choices, takes hardware and software costs into account and makes a number of recommendations.

    2003-06-01

    Plants will play an essential role in providing life support for any long-term space exploration or habitation. We are evaluating the feasibility of an adaptable system for measuring the response of plants to any unique space condition and optimizing plant performance under those conditions. The proposed system is based on a unique combination of systems including the rapid advances in the field of plant genomics, microarray technology for measuring gene expression, bioinformatics, gene pathways and networks, physiological measurements in controlled environments, and advances in automation and robotics. The resulting flexible module for monitoring and optimizing plant responses will be able to be inserted as a cassette into a variety of platforms and missions for either experimental or life support purposes. The results from future plant functional genomics projects have great potential to be applied to those plant species most likely to be used in space environments. Eventually, it will be possible to use the plant genetic assessment and control system to optimize the performance of any plant in any space environment. In addition to allowing the effective control of environmental parameters for enhanced plant productivity and other life support functions, the proposed module will also allow the selection or engineering of plants to thrive in specific space environments. The proposed project will advance human exploration of space in the near- and mid-term future on the International Space Station and free-flying satellites and in the far-term for longer duration missions and eventual space habitation.

    2002-01-01

    The Virtual Mission Operations Center - Collaborative Environment (VMOC-CE) intent is to have a central access point for all the resources used in a collaborative mission operations environment to assist mission operators in communicating on-site and off-site in the investigation and resolution of anomalies. It is a framework that as a minimum incorporates online chat, realtime file sharing and remote application sharing components in one central location. The use of a collaborative environment in mission operations opens up the possibilities for a central framework for other project members to access and interact with mission operations staff remotely. The goal of the Virtual Mission Operations Center (VMOC) Project is to identify, develop, and infuse technology to enable mission control by on-call personnel in geographically dispersed locations. In order to achieve this goal, the following capabilities are needed: Autonomous mission control systems Automated systems to contact on-call personnel Synthesis and presentation of mission control status and history information Desktop tools for data and situation analysis Secure mechanism for remote collaboration commanding Collaborative environment for remote cooperative work The VMOC-CE is a collaborative environment that facilitates remote cooperative work. It is an application instance of the Virtual System Design Environment (VSDE), developed by NASA Goddard Space Flight Center's (GSFC) Systems Engineering Services & Advanced Concepts (SESAC) Branch. The VSDE is a web-based portal that includes a knowledge repository and collaborative environment to serve science and engineering teams in product development. It is a "one stop shop" for product design, providing users real-time access to product development data, engineering and management tools, and relevant design specifications and resources through the Internet. The initial focus of the VSDE has been to serve teams working in the early portion of the system

    Physics in a many-center environment was born as the electron physics of metals. Electrons moving from the electrolyte of a battery to anode metal become quasi-particles with a many-centers geometry. The Ion Band State Theory of cold fusion assumes that a fraction of the deuterons in PdDx reconfigure to a many-centers geometry. Many-center geometry seems to apply to deuteron populations in nano-metal crystals as studied by Arata and Zhang, to Bloch-sensitive nuclei created in Iwamura's permeation studies, to the metastable nuclei forming alpha shower flakes as discovered by Oriani and Fisher and reproducibly produced by P. Mosier-Boss. T.A. Chubb, Infinite Energy, Issue 70, in press (2006) T.A. Chubb, ``Many-Centers Nuclei,'' submitted to Infinite Energy T.A. Chubb and S.R. Chubb, Fusion Technol.,20, 93 (1991).

    Launch vehicles within the international community vary greatly in their configuration and processing. Each launch site has a unique processing flow based on the specific launch vehicle configuration. Launch and flight operations are managed through a set of control centers associated with each launch site. Each launch site has a control center for launch operations; however flight operations support varies from being co-located with the launch site to being shared with the space vehicle control center. There is also a nuance of some having an engineering support center which may be co-located with either the launch or flight control center, or in a separate geographical location altogether. A survey of control center architectures is presented for various launch vehicles including the NASA Space Launch System (SLS), United Launch Alliance (ULA) Atlas V and Delta IV, and the European Space Agency (ESA) Ariane 5. Each of these control center architectures shares some similarities in basic structure while differences in functional distribution also exist. The driving functions which lead to these factors are considered and a model of control center architectures is proposed which supports these commonalities and variations.

    To investigate use of an improved ocular tear film analysis protocol (OPI 2.0) in the Controlled Adverse Environment (CAE(SM)) model of dry eye disease, and to examine the utility of new metrics in the identification of subpopulations of dry eye patients. Thirty-three dry eye subjects completed a single-center, single-visit, pilot CAE study. The primary endpoint was mean break-up area (MBA) as assessed by the OPI 2.0 system. Secondary endpoints included corneal fluorescein staining, tear film break-up time, and OPI 2.0 system measurements. Subjects were also asked to rate their ocular discomfort throughout the CAE. Dry eye endpoints were measured at baseline, immediately following a 90-minute CAE exposure, and again 30 minutes after exposure. The post-CAE measurements of MBA showed a statistically significant decrease from the baseline measurements. The decrease was relatively specific to those patients with moderate to severe dry eye, as measured by baseline MBA. Secondary endpoints including palpebral fissure size, corneal staining, and redness, also showed significant changes when pre- and post-CAE measurements were compared. A correlation analysis identified specific associations between MBA, blink rate, and palpebral fissure size. Comparison of MBA responses allowed us to identify subpopulations of subjects who exhibited different compensatory mechanisms in response to CAE challenge. Of note, none of the measures of tear film break-up time showed statistically significant changes or correlations in pre-, versus post-CAE measures. This pilot study confirms that the tear film metric MBA can detect changes in the ocular surface induced by a CAE, and that these changes are correlated with other, established measures of dry eye disease. The observed decrease in MBA following CAE exposure demonstrates that compensatory mechanisms are initiated during the CAE exposure, and that this compensation may provide the means to identify and characterize clinically relevant

    1993-01-01

    The Solar Anomolous and Magnetospheric Explorer (SAMPEX) satellite was launched in July 1992. It was the first in the NASA Small Explorer (SMEX) series. In building the real-time control center facility, several new mission support challenges had to be met: CCSDS telemetry and command format, 900 Kbps telemetry data, and shorter turn-around time for control center development than previous missions. The SAMPEX Payload Operations Control Ccnter (POCC) was also the first control center for a new satellite to be based on the Transportable Payload Operations Control Center (TPOCC) system architecture and methodology. This approach has both guided the implementation of the SAMPEX control center and provided some of the building blocks. By using the TPOCC architecture to build the SAMPEX POCC, the real-time operations area was miniaturized into one room, whereas previous missions needed multiple large rooms. The development cost of the SAMPEX POCC was reduced from previous missions and will provide for further cost savings in the future SMEX satellites. This paper describes the system as built and some of the enhancements in progress to create this teleoperations environment.

  16. Environment control system

    DOEpatents

    Sammarone, Dino G.

    1978-01-01

    A system for controlling the environment of an enclosed area in nuclear reactor installations. The system permits the changing of the environment from nitrogen to air, or from air to nitrogen, without the release of any radioactivity or process gas to the outside atmosphere. In changing from a nitrogen to an air environment, oxygen is inserted into the enclosed area at the same rate which the nitrogen-oxygen gas mixture is removed from the enclosed area. The nitrogen-oxygen gas mixture removed from the enclosed area is mixed with hydrogen, the hydrogen recombining with the oxygen present in the gas to form water. The water is then removed from the system and, if it contains any radioactive products, can be utilized to form concrete, which can then be transferred to a licensed burial site. The process gas is purified further by stripping it of carbon dioxide and then distilling it to remove any xenon, krypton, and other fission or non-condensable gases. The pure nitrogen is stored as either a cryogenic liquid or a gas. In changing from an air to nitrogen environment, the gas is removed from the enclosed area, mixed with hydrogen to remove the oxygen present, dried, passed through adsorption beds to remove any fission gases, and reinserted into the enclosed area. Additionally, the nitrogen stored during the nitrogen to air change, is inserted into the enclosed area, the nitrogen from both sources being inserted into the enclosed area at the same rate as the removal of the gas from the containment area. As designed, the amount of nitrogen stored during the nitrogen to air change substantially equals that required to replace oxygen removed during an air to nitrogen change.

    Swarbrick, Margaret; Schmidt, Lisa T; Pratt, Carlos W

    2009-07-01

    Consumer-operated self-help centers were designed to provide social environments that promote participant empowerment and satisfaction. This exploratory, descriptive study examined how variance in empowerment and satisfaction scores could be explained by participants' perceptions of the social environment factors (relationship, personal growth, and systems maintenance and change) and quantity of participation. Participants (N = 144) involved in consumer-operated self-help centers completed a four-part, 161-item survey designed to capture perceptions of satisfaction, empowerment, social environment factors, quantity of center participation, and demographic data. Significant relationships were found between participant satisfaction and the three social environment factors. Findings also indicated that participant empowerment was related to quantity of self-help center involvement. From these exploratory analyses, recommendations are made on how to improve consumer-run self-help center operations.

    1988-01-01

    To assess the cost and area/volume requirements of a farm in a space station or Lunar or Martian base, a few laboratories in the United States, the Soviet Union, France, and Japan are studying optimum controlled environments for the production of selected crops. Temperature, light, photoperiod, CO2, humidity, the root-zone environment, and cultivars are the primary factors being manipulated to increase yields and harvest index. Our best wheat yields on a time basis (24 g m-2 day-1 of edible biomass) are five times good field yields and twice the world record. Similar yields have been obtained in other laboratories with potatoes and lettuce; soybeans are also promising. These figures suggest that approximately 30 m2 under continuous production could support an astronaut with sufficient protein and about 2800 kcal day-1. Scientists under Iosif Gitelzon in Krasnoyarsk, Siberia, have lived in a closed system for up to 5 months, producing 80% of their own food. Thirty square meters for crops were allotted to each of the two men taking part in the experiment. A functional controlled-environment life-support system (CELSS) will require the refined application of several disciplines: controlled-environment agriculture, food preparation, waste disposal, and control-systems technology, to list only the broadest categories. It has seemed intuitively evident that ways could be found to prepare food, regenerate plant nutrients from wastes, and even control and integrate several subsystems of a CELSS. But could sufficient food be produced in the limited areas and with the limited energy that might be available? Clearly, detailed studies of food production were necessary.

  9. Capaciflector-based virtual force control and centering

    NASA Technical Reports Server (NTRS)

    Nguyen, Charles C.

    1993-01-01

    This report presents a novel concept of force control, called virtual force control. The virtual force concept avoids sudden step transition of position control to contact force control resulting in contact force disturbance when a robot end-effector makes contact with the environment. A virtual force/position control scheme consists of two loops: the force control loop and the position control loop. While the position control loop regulates the free motion, the force control loop regulates the contact force after making contact with the environment and the virtual force measured by a range sensor called capaciflector in the virtual environment. After presenting the concept of virtual force control, the report introduces a centering scheme in which the virtual force controller is employed to measure three points on a cone so that its center can be located. Experimental results of a one-degree-of-freedom virtual force control scheme applied in berthing an orbital replaceable unit are reported and compared with those of conventional pure contact force control cases.

  12. Space weather activities at NOAA s Space Environment Center

    NASA Astrophysics Data System (ADS)

    Kunches, J.

    The NOAA Space Environment Center is the focal point for real-time space weather monitoring and prediction in the United States . The Space Weather Operations (SWO) division staffs a 24-hour/day operations center, through which both in-situ and remotely sensed data and imagery flow. These diverse data streams are analyzed continuously, and that information is applied to both predictions and specifications of various aspects of the space environment. These include the behavior of the geomagnetic field, the character of the ionosphere, and the strength of the near-earth radiation environment. Models are brought to bear in each of thes e areas, as SEC has an active research-to-operations transition effort. The Rapid Prototyping Center is the venue through which pertinent models and data must pass to be brought into the operational arena. The model outputs are then made available both internally and externally. SEC is a member of the International Space Environment Service (ISES), a partnership currently consisting of eleven nations. The mission of the ISES is to encourage and facilitate near-real-time international monitoring and prediction of the space environment by: the rapid exchange of space environment information; the standardization of the methodology for space environment observations and data reduction; the uniform publication of observations and statistics; and the application of standardized space environment products and services to assist users in reducing the impact of space weather on activities of human interest. An overview of the operational attributes of the SEC, and the function of the ISES, will be presented. Additional issues related to space weather customers, new data streams to be available in the near-term, and how these new data and imagery will be integrated int o operations will be discussed.

    Children are sensitive to indoor environmental pollution. Up until now there has been a lack of data on air quality in child day care centers. The aim of this study is to document the indoor environment quality of Paris child day care centers by repeated measurements, and to compare pollutant levels in child day care centers with levels in Paris dwellings. We selected 28 child day care centers frequented by a random sample of babies who participated in the PARIS birth cohort environmental investigation, and visited the child day care centers for one week twice in one year. Biological contaminants assessed were fungi, endotoxin, dust mite allergens, and chemical pollutants: aldehydes, volatile organic compounds and nitrogen dioxide (NO2). Relative humidity, temperature, and carbon dioxide levels were measured simultaneously. A standardized questionnaire was used to gather information about the buildings and their inhabitants. Airborne endotoxin levels in child day care centers were higher than those found in Paris dwellings. Dust mite allergens in child day care centers were below the threshold level for sensitization in the majority of samples, and in common with dwelling samples. Penicillium and Cladosporium were the most commonly identified genera fungi. The child day care center indoor/outdoor ratio for most chemical pollutants was above unity except for NO2, the levels for NO2 being significantly higher than those measured in homes. Chemical and biological contamination in child day care centers appears to be low, apart from endotoxin and NO2. Failure to take child exposure in child day care centers into account could result in an overestimation of children's exposure to other pollutants. Copyright © 2011 Elsevier Inc.

  15. Operating and Managing a Backup Control Center

    2010-01-01

    Due to the criticality of continuous mission operations, some control centers must plan for alternate locations in the event an emergency shuts down the primary control center. Johnson Space Center (JSC) in Houston, Texas is the Mission Control Center (MCC) for the International Space Station (ISS). Due to Houston s proximity to the Gulf of Mexico, JSC is prone to threats from hurricanes which could cause flooding, wind damage, and electrical outages to the buildings supporting the MCC. Marshall Space Flight Center (MSFC) has the capability to be the Backup Control Center for the ISS if the situation is needed. While the MSFC Huntsville Operations Support Center (HOSC) does house the BCC, the prime customer and operator of the ISS is still the JSC flight operations team. To satisfy the customer and maintain continuous mission operations, the BCC has critical infrastructure that hosts ISS ground systems and flight operations equipment that mirrors the prime mission control facility. However, a complete duplicate of Mission Control Center in another remote location is very expensive to recreate. The HOSC has infrastructure and services that MCC utilized for its backup control center to reduce the costs of a somewhat redundant service. While labor talents are equivalent, experiences are not. Certain operations are maintained in a redundant mode, while others are simply maintained as single string with adequate sparing levels of equipment. Personnel at the BCC facility must be trained and certified to an adequate level on primary MCC systems. Negotiations with the customer were done to match requirements with existing capabilities, and to prioritize resources for appropriate level of service. Because some of these systems are shared, an activation of the backup control center will cause a suspension of scheduled HOSC activities that may share resources needed by the BCC. For example, the MCC is monitoring a hurricane in the Gulf of Mexico. As the threat to MCC

    Distribution centers location problem is concerned with how to select distribution centers from the potential set so that the total relevant cost is minimized. This paper mainly investigates this problem under fuzzy environment. Consequentially, chance-constrained programming model for the problem is designed and some properties of the model are investigated. Tabu search algorithm, genetic algorithm and fuzzy simulation algorithm are integrated to seek the approximate best solution of the model. A numerical example is also given to show the application of the algorithm.

    1987-01-01

    The present optimization study for maximum yield and quality conditions in the lunar or Martian Controlled Environment Life Support System (CELSS)-based growth of wheat has determined that, for 23-57 g/sq m per day of edible biomass, minimum CELSS size must be of the order of 12-30 sq m/person. About 600 W/sq m of electricity would be consumed by the artificial lighting required; temperature, irradiance, photoperiod, CO2 levels, humidity, and wind velocity are all controlled. A rock wool plant support allows direct seeding, and densities of up to 10,000 plants/sq m. Densities of up to 2000 plants/sq m appear to increase seed yields.

    The Payload Operations Integration Center (POIC) at the Marshall Space Flight Center supports the International Space Station (ISS) through remote interfaces around the world. The POIC was originally designed as a gateway to space for remote facilities; ranging from an individual user to a full-scale multiuser environment. This achievement was accomplished while meeting program requirements and accommodating the injection of modern technology on an ongoing basis to ensure cost effective operations. This paper will discuss the open POIC architecture developed to support similar and dissimilar remote operations centers. It will include technologies, protocols, and compromises which on a day to day basis support ongoing operations. Additional areas covered include centralized management of shared resources and methods utilized to provide highly available and restricted resources to remote users. Finally, the effort of coordinating the actions of participants will be discussed.

    Conditions are optimized for maximum yield and quality of wheat to be used in a controlled environment life support system (CELSS) in a Lunar or Martian base or a spacecraft. With yields of 23 to 57 g/sq m/d of edible biomass, a minimum size for a CELSS would be between 12 and 30 sq m per person, utilizing about 600 W/sq m of electrical energy for artificial light. Temperature, irradiance, photoperiod, carbon dioxide levels, humidity, and wind velocity are controlled in growth chambers. Nutrient solutions (adjusted for wheat) are supplied to the roots via a recirculating system that controls pH by adding HNO3 and controlling the NO3/NH4 ratio in solution. A rock-wool plant support allows direct seeding and densities up to 10,000 plants sq m. Densities up to 2000 plants/sq m appear to increase seed yield. Biomass production increases almost linearily with increasing irradiance from 400 to 1700 micromol/sq m/s of photosynthetic photon flux, but the efficiency of light utilization decreases over this range. Photoperiod and temperature both have a profound influence on floral initiation, spikelet formation, stem elongation, and fertilization.

    Our goal is to optimize conditions for maximum yield and quality of wheat to be used in a controlled-environment, life-support system (CELSS) in a Lunar or Martian base or perhaps in a space craft. With yields of 23 to 57 g m-2 d-1 of edible biomass, a minimum size for a CELSS would be between 12 and 30 m2 per person, utilizing about 600 W m-2 of electrical energy for artificial light. Temperature, irradiance, photoperiod, carbon-dioxide levels, humidity, and wind velocity are controlled in state-of-the-art growth chambers. Nutrient solutions (adjusted for wheat) are supplied to the roots via a recirculating system that controls pH by adding HNO3 and controlling the NO3/NH4 ratio in solution. A rock-wool plant support allows direct seeding and densities up to 10,000 plants per meter2. Densities up to 2000 plants m-2 appear to increase seed yield. Biomass production increases almost linearily with increasing irradiance from 400 to 1700 μmol m-2 s-1 of photosynthetic photon flux (PPF), but the efficiency of light utilization decreases over this range. Photoperiod and temperature both have a profound influence on floral initiation, spikelet formation, stem elongation, and fertilization. High temperatures (25 to 27°C) and long days shorten the life cycle and promote rapid growth, but cooler temperatures (20°C) and shorter days greatly increase seed number per head and thus yield (g m-2). The life cycle is lengthened in these conditions but yield per day (g m-2 d-1) is still increased. We have evaluated about 600 cultivars from around the world and have developed several breeding lines for our controlled conditions. Some of our ultra-dwarf lines (30 to 50 cm tall) look especially promising with high yields and high harvest indices (percent edible biomass).

    2016-05-01

    Nitrogen-vacancy (NV) centers in diamond have emerged as a versatile atom-like system, finding diverse applications in metrology and quantum information science, but interaction between the NV center's electronic spin and its nuclear spin environment represent a major source of decoherence. We use optical techniques to monitor and control the nuclear bath surrounding an NV center. Specifically, we create an optical Λ-system using the | +/- 1 > components of the NV center's spin-triplet ground state. When the Zeeman splitting between the two states is equal to the two-photon detuning between the lasers, population is trapped in the resulting dark state. Measuring the rate at which the NV center escapes from the dark state therefore gives information on how spin bath dynamics change the effective magnetic field experienced by the NV center. By monitoring statistics of the emitted photons, we plan to probe non-equilibrium dynamics of the bath.

    This paper describes the capabilities and features of the X-33 Range Operations Center at NASA Dryden Flight Research Center. All the unprocessed data will be collected and transmitted over fiber optic lines to the Lockheed Operations Control Center for real-time flight monitoring of the X-33 vehicle. By using the existing capabilities of the Western Aeronautical Test Range, the Range Operations Center will provide the ability to monitor all down-range tracking sites for the Extended Test Range systems. In addition to radar tracking and aircraft telemetry data, the Telemetry and Radar Acquisition and Processing System is being enhanced to acquire vehicle command data, differential Global Positioning System corrections and telemetry receiver signal level status. The Telemetry and Radar Acquisition Processing System provides the flexibility to satisfy all X-33 data processing requirements quickly and efficiently. Additionally, the Telemetry and Radar Acquisition Processing System will run a real-time link margin analysis program. The results of this model will be compared in real-time with actual flight data. The hardware and software concepts presented in this paper describe a method of merging all types of data into a common database for real-time display in the Range Operations Center in support of the X-33 program. All types of data will be processed for real-time analysis and display of the range system status to ensure public safety.

    CNES(F) is responsible for the development of a new generation of Operational Control Center (CMP) which will operate the new heliosynchronous remote sensing satellite (SPOT4). This Operational Control Center takes large benefit from the experience of the first generation of control center and from the recent advances in computer technology and standards. The CMP is designed for operating two satellites all the same time with a reduced pool of controllers. The architecture of this CMP is simple, robust, and flexible, since it is based on powerful distributed workstations interconnected through an Ethernet LAN. The application software uses modern and formal software engineering methods, in order to improve quality and reliability, and facilitate maintenance. This software is table driven so it can be easily adapted to other operational needs. Operation tasks are automated to the maximum extent, so that it could be possible to operate the CMP automatically with very limited human interference for supervision and decision making. This paper provides an overview of the SPOTS mission and associated ground segment. It also details the CMP, its functions, and its software and hardware architecture.

  3. Delivering risk information in a dynamic information environment: Framing and authoritative voice in Centers for Disease Control (CDC) and primetime broadcast news media communications during the 2014 Ebola outbreak.

    PubMed

    Kott, Anne; Limaye, Rupali J

    2016-11-01

    During a disease outbreak, media serve as primary transmitters of information from public health agencies to the public, and have been shown to influence both behavior and perception of risk. Differences in news frequency, framing and information source can impact the public's interpretation of risk messages and subsequent attitudes and behaviors about a particular threat. The media's framing of an outbreak is important, as it may affect both perception of risk and the ability to process important health information. To understand how risk communication by the Centers for Disease Control and Prevention (CDC) during the 2014 Ebola outbreak was framed and delivered and to what extent primetime broadcast news media mirrored CDC's framing and authoritative voice, 209 CDC communications and primetime broadcast transcripts issued between July 24 and December 29, 2014 were analyzed and coded by thematic frame and authoritative voice. Dominant frame and voice were determined for each month and for overall period of analysis. Medical frame was dominant in CDC (60%), Anderson Cooper 360 (49%), The Rachel Maddow Show (47%) and All In with Chris Hayes (47%). The human interest frame was dominant in The Kelly File (45%), while The O'Reilly Factor coverage was equally split between sociopolitical and medical frames (28%, respectively). Primetime news media also changed dominant frames over time. Dominant authoritative voice in CDC communications was that of CDC officials, while primetime news dominantly featured local and federal (non-CDC) government officials and academic/medical experts. Differences in framing and delivery could have led the public to interpret risk in a different way than intended by CDC. Overall, public health agencies should consider adapting risk communication strategies to account for a dynamic news environment and the media's agenda. Options include adapting communications to short-form styles and embracing the concept of storytelling. Copyright © 2016

  4. Re-engineering regional poison control center services.

    PubMed

    Wieland, M J

    1996-04-01

    In summary, I propose a model of poison control service delivery to replace poison control centers. A handful of financially self-sustaining poison consult centers would remain. All other services would be provided by health plans to their members, including those covered under State-funded managed care. The need for continued fundraising efforts would be eliminated. Rather than devoting large sums of money to consolidate the State's 6 centers into 1 large center, I encourage Blue Cross of California to fund the protocol development process that will drive a true restructuring effort for poison control services. In our hearts, if our goal is to ensure continued service provision, then let's take the initiative to re-engineer the way we do business. The risks of doing nothing more than seek continued funding for the existing service delivery model should be painfully obvious by now. If your individual goals include survival for your center, then there's great news. The demand for call centers providing a wide range of advice services is approaching a critical level. Most health and hospital systems are moving to a managed care environment. Health care delivery is quickly moving out of the hospital to ambulatory services. Telemedicine is here--and growing very quickly. Distance learning technology is knocking at the door. There is plenty to do. With sound strategic development, your center will survive--it just won't look or feel the same as its does today. Survival the way it used to be ...uh, except for the computers and stuff.

    2015-12-01

    The technology and computer science registered a large development in the last years. Most systems that use high technologies require special working conditions. The monitoring and the controlling are very important. The temperature and the humidity are important parameters in the operation of computer systems, industrial and research, maintaining it between certain values to ensure their proper functioning being important. Usually, the temperature is maintained in the established range using an air conditioning system, but the humidity is affected. In the present work we developed an application based on a board with own firmware called "AVR_NET_IO" using a microcontroller ATmega32 type for temperature and humidity monitoring in Data Center of INCDTIM. On this board, temperature sensors were connected to measure the temperature in different points of the Data Center and outside of this. Humidity monitoring is performed using data from integrated sensors of the air conditioning system, thus achieving a correlation between humidity and temperature variation. It was developed a software application (CM-1) together with the hardware, which allows temperature monitoring and register inside Data Center and trigger an alarm when variations are greater with 3°C than established limits of the temperature.

    1988-01-01

    The spacecraft command/control environment is becoming increasingly complex. As we enter the era of Space Station and the era of more highly automated systems, it is evident that the critical roles played by operations personnel in supervising the many required control center system components is becoming more cognitively demanding. In addition, the changing and emerging roles in the operations picture have far-reaching effects on the achievement of mission objectives. Thus highly trained and competent operations personnel are mandatory for success. Keeping pace with these developments has been computer-aided instruction utilizing various artificial intelligence technologies. The impacts of this growing capability on the stringent requirements for efficient and effective control center operations personnel is an area of much concentrated study. Some of the research and development of automated tutoring systems for the spacecraft command/control environment is addressed.

    Center of gravity (CG) is likely to be an important variable in astronaut performance during partial gravity extravehicular activity (EVA). The Apollo Lunar EVA experience revealed challenges with suit stability and control. The EVA Physiology, Systems and Performance Project (EPSP) in conjunction with the Constellation EVA Systems Project Office have developed plans to systematically understand the role of suit weight, CG and suit pressure on astronaut performance in partial gravity environments. This presentation based upon CG studies seeks to understand the impact of varied CG on human performance in lunar gravity.

  16. Effect of production environment on labor demand in Veterans Affairs medical center pharmacies.

    PubMed

    Brooks, J M; Kirking, D M

    1995-04-15

    The relationship between pharmacy production environment and labor-time requirements was estimated by using data from Veterans Affairs medical center (VAMC) pharmacies. Economic theory was used to derive equations for estimating labor-time requirements for pharmacy services that take into account differences in production environment (factors that cannot be controlled by the pharmacy manager within a given observation period, such as pharmacy service mix and distance to patient care wards). The equations were estimated by using information obtained from the Department of Veterans Affairs (VA) and from a mail survey of VAMC pharmacy chiefs. The resulting estimates of labor-time requirements were compared with pharmacy labor-time requirements produced by the VA in 1989. Labor-time requirements varied dramatically with production environment, and the labor-time requirements calculated in this study generally exceeded those used by the VA. Accurate forecasts of required pharmacist and technician labor time must take into account the production environment within each pharmacy.

  18. Preventing racism and promoting social justice: person-centered and environment-centered interventions.

    PubMed

    Buhin, Larisa; Vera, Elizabeth M

    2009-01-01

    This paper proposes that prevention of racism is a social justice issue in light of the pervasively detrimental effects of racism on all members of our society and the especially traumatizing effects for people of color. Review of contact theory and its extensions provides the theoretical background for person-focused prevention strategies. Specifically, the paper describes a model primary prevention program to address the development of racist attitudes and beliefs in White children as a way of stopping future racist traumatization of people of color. Advocating for public policy changes is discussed as a valuable environment-centered prevention tool in working toward social justice. Implications for training incorporating multicultural counseling competencies, critical psychology, prevention science, and advocacy are discussed.

  20. Environment and health: Probes and sensors for environment digital control

    NASA Astrophysics Data System (ADS)

    Schettini, Chiara

    2014-05-01

    The idea of studying the environment using New Technologies (NT) came from a MIUR (Ministry of Education of the Italian Government) notice that allocated funds for the realization of innovative school science projects. The "Environment and Health" project uses probes and sensors for digital control of environment (water, air and soil). The working group was composed of 4 Science teachers from 'Liceo Statale G. Mazzini ', under the coordination of teacher Chiara Schettini. The Didactic Section of Naples City of Sciences helped the teachers in developing the project and it organized a refresher course for them on the utilization of digital control sensors. The project connects Environment and Technology because the study of the natural aspects and the analysis of the chemical-physical parameters give students and teachers skills for studying the environment based on the utilization of NT in computing data elaboration. During the practical project, samples of air, water and soil are gathered in different contexts. Sample analysis was done in the school's scientific laboratory with digitally controlled sensors. The data are elaborated with specific software and the results have been written in a booklet and in a computing database. During the first year, the project involved 6 school classes (age of the students 14—15 years), under the coordination of Science teachers. The project aims are: 1) making students more aware about environmental matters 2) achieving basic skills for evaluating air, water and soil quality. 3) achieving strong skills for the utilization of digitally controlled sensors. 4) achieving computing skills for elaborating and presenting data. The project aims to develop a large environmental conscience and the need of a ' good ' environment for defending our health. Moreover it would increase the importance of NT as an instrument of knowledge.

  5. Analyzing the teaching style of nursing faculty. Does it promote a student-centered or teacher-centered learning environment?

    PubMed

    Schaefer, Karen Moore; Zygmont, Dolores

    2003-01-01

    The purposes of this study were to a) describe the predominant teaching style of a group of nursing faculty members, either as teacher centered or student centered, and b) to compare teaching style to the instructional methods the faculty members used in the courses they taught and to their stated philosophies of teaching/learning. Findings indicate that the participants were more teacher centered than student centered; their written philosophies supported the teacher-centered approach. However, evidence that faculty used student-centered language, often in a teacher-centered context, indicates that participants in the study may recognize the need for a student-centered environment but may have difficulty with implementation. Recommendations for faculty members and administrators are offered.

  12. NASA's Contributions to Controlled Environment Agriculture

    Wheeler, Raymond M.

    2016-01-01

    It may come as a surprise, but NASA has been a long-standing sponsor of controlled environment agriculture (CEA) research. This is based on the potential for using plants (crops) for life support systems in space. Through photosynthesis, crops could produce food and oxygen for humans, while removing CO2. In addition, plant transpiration could help purify waste water. NASAs interest in bioregenerative life support dates back to the late 1950s. At that time, much of the testing focused on algae, but over the years moved toward higher plants as CEA techniques improved. Throughout the 1980s and 90s, extensive testing was carried out at different universities to gather horticultural data for a range of crops, including wheat, soybean, lettuce, potato, sweet potato, cowpea, rice and more. These studies examined different electric light sources, mineral nutrition, recirculating hydroponics, effects of CO2, temperature, photosynthetic photon flux (PPF), and photoperiod on the crops, and identified cultivars that would be useful for space. Findings from these studies were then used to conduct large scale (20 sq m), closed atmosphere tests at Kennedy Space Center, and later at NASA Johnson Space Center, where plant growth chambers were linked to human habitats. Results showed that with high light input and careful horticultural management, about 20-25 sq m of crops under continuous cultivation could produce the O2 for one person, and about 40-50 sq m could produce enough dietary calories. The ability to sustain these production levels and accurately assess system costs and failures needs further study. In all likelihood, the use of plants for life support will evolve, where for early missions like the International Space Station, crops will be grown in small chambers to provide supplemental fresh foods. As mission durations and distances increase, the systems could expand to assume more of the life support burden. But the constraints of space travel require that these

    The energy management system (EMS) industry is presenting the utility end-user a backdrop of competing choices and complex technology trends. Understanding new trends, such as open architecture computer configurations, local area networks, microcomputer EMSs, full graphics, and artificial intelligence requires a high level of experience and data gathering. This article conceptually describes the ability to migrate applications among computers of different vendors and different sizes (from PCs to supercomputers), as operating needs change and grow. The essential thrust of this article is to answer the questions many utility practitioners have been asking about open systems, standards, architectures, and available choices. These questions are fundamental to providing a computational application environment in which the tools required for intelligent and adaptive power system control can be operated. These tools are being designed for standards-driven, open-hardware platforms. Users are offered many choices of how to modify their EMS systems and must prepare their staffs to participate in the explosion of new technology.

    The present study compared the accuracy of cue-outcome knowledge gained during prediction-based and control-based learning in stable and unstable dynamic environments. Participants either learnt to make cue-interventions in order to control an outcome, or learnt to predict the outcome from observing changes to the cue values. Study 1 (N = 60) revealed that in tests of control, after a short period of familiarization, performance of Predictors was equivalent to Controllers. Study 2 (N = 28) showed that Controllers showed equivalent task knowledge when to compared to Predictors. Though both Controllers and Predictors showed good performance at test, overall Controllers showed an advantage. The cue-outcome knowledge acquired during learning was sufficiently flexible to enable successful transfer to tests of control and prediction. PMID:22419913

    1995-03-01

    When asked what comes to mind when they think of ``controlling work`` in the office, people may respond with ``overbearing boss,`` ``no autonomy,`` or ``Theory X management.`` The idea of controlling work in white collar or administrative environments can have a negative connotation. However, office life is often chaotic and miserable precisely because the work processes are out of control, and managers must spend their time looking over people`s shoulders and fighting fires. While management styles and structures vary, the need for control of work processes does not. Workers in many environments are being reorganized into self-managed work teams. These teams are expected to manage their own work through increased autonomy and empowerment. However, even empowered work teams must manage their work processes because of process variation. The amount of incoming jobs vary with both expected (seasonal) and unexpected demand. The mixture of job types vary over time, changing the need for certain skills or knowledge. And illness and turnover affect the availability of workers with needed skills and knowledge. Clearly, there is still a need to control work, whether the authority for controlling work is vested in one person or many. Visual control concepts provide simple, inexpensive, and flexible mechanisms for managing processes in work teams and continuous improvement administrative environments.

    Automatic recognition, inspection, manipulation and assembly of objects will be a common denominator in most of tomorrow's highly automated factories. These tasks will be handled by intelligent computer controlled robots with multisensor capabilities which contribute to desired flexibility and adaptability. The control of a robot in such a multisensor environment becomes of crucial importance as the complexity of the problem grows exponentially with the number of sensors, tasks, commands and objects. In this paper we present an approach which uses CAD (Computer-Aided Design) based geometric and functional models of objects together with action oriented neuroschemas to recognize and manipulate objects by a robot in a multisensor environment. The hierarchical robot control system is being implemented on a BBN Butterfly multi processor.

Thus this workshop was convened to reevaluate the technology that is available today and to work toward developing guidelines for the most effective use of lighting in controlled environments with emphasis on lighting for plants but also to initiate interest in the development of improved guidelines for human and animal research. There are a number of established guidelines for lighting in human and animal environments. Development of new lighting guidelines is necessary for three reasons: (1) recent scientific discoveries show that in addition to supporting the sensation of vision, light has profound nonvisual biological and behavioral effects in both animals and humans; (2) federal regulations (EPACT 1992) are requiring all indoor environments to become more energy efficient with a specific emphasis on energy conservation in lighting; (3) lighting engineers and manufacturers have developed a wealth of new light sources and lighting products that can be applied in animal and human environments. The workshop was aimed at bringing together plant scientists and physical scientists to interact in the discussions. It involved participation of biological scientists involved in studying mechanisms of light reactions and those involved in utilizing lighting for production of plants and maintenance of animals in controlled environments. It included participation of physical scientists from universities and government involved in research as well as those from industry involved in producing lamps and in construction of controlled growth facilities. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.

  16. Interactive Formation Control in Complex Environments.

    PubMed

    Henry, Joseph; Shum, Hubert P H; Komura, Taku

    2013-08-13

    The degrees of freedom of a crowd is much higher than that provided by a standard user input device. Typically, crowd control systems require multiple passes to design crowd movements by specifying waypoints, and then defining character trajectories and crowd formation. Such multi-pass control would spoil the responsiveness and excitement of real-time control systems. In this paper, we propose a single-pass algorithm to control a crowd in complex environments. We observe that low level details in crowd movement are related to interactions between characters and the environment, such as diverging/merging at cross points, or climbing over obstacles. Therefore, we simplify the problem by representing the crowd with a deformable mesh, and allow the user, via multi-touch input, to specify high level movements and formations that are important for context delivery. To help prevent congestion, our system dynamically reassigns characters in the formation by employing a mass transport solver to minimise their overall movement. The solver uses a cost function to evaluate the impact from the environment, including obstacles and areas affecting movement speed. Experimental results show realistic crowd movement created with minimal high-level user inputs. Our algorithm is particularly useful for real-time applications including strategy games and interactive animation creation.

  18. Active vibration control in microgravity environment

    Gerhold, Carl H.

    1987-01-01

    The low gravity environment of the space station is suitable for experiments or manufacturing processes which require near zero gravity. An experiment was fabricated to test the validity of the active control process and to verify the flow and control parameters identified in a theoretical model. Zero gravity is approximated in the horizontal plane using a low friction air bearing table. An analog control system was designed to activate calibrated air jets when displacement of the test mass is sensed. The experiment demonstrates that an air jet control system introduces an effective damping factor to control oscillatory response. The amount of damping as well as the flow parameters, such as pressure drop across the valve and flow rate of air, are verified by the analytical model.

  19. Homeostasis control of building environment using sensor agent robot

    NASA Astrophysics Data System (ADS)

    Nagahama, Eri; Mita, Akira

    2012-04-01

    A human centered system for building is demanded to meet variety of needs due to the diversification and maturation of society. Smart buildings and smart houses have been studied to satisfy this demand. However, it is difficult for such systems to respond flexibly to unexpected events and needs that are caused by aging and complicate emotion changes. With this regards, we suggest "Biofied Buildings". The goal for this research is to realize buildings that are safer, more comfortable and more energy-efficient by embedding adaptive functions of life into buildings. In this paper, we propose a new control system for building environments, focused on physiological adaptation, particularly homeostasis, endocrine system and immune system. Residents are used as living sensors and controllers in the control loop. A sensor agent robot is used to acquire resident's discomfort feeling, and to output hormone-like signals to activate devices to control the environments. The proposed system could control many devices without establishing complicated scenarios. Results obtained from some simulations and the demonstration experiments using an LED lighting system showed that the proposed system were able to achieve robust and stable control of environments without complicated scenarios.

  20. Common front end systems for Space Shuttle and Space Station control centers at Johnson Space Center

    NASA Technical Reports Server (NTRS)

    Uljon, Linda; Muratore, John

    1993-01-01

    In the beginning of the fiscal year 1992, the development organizations of Johnson Space Center (JSC) were poised to begin two major projects: the Space Station Control Center and the refurbishment of the telemetry processing area of the Space Shuttle Mission Control Center. A study team established that a common front end concept could be used and could reduce development costs for both projects. A standard processor was defined to support most of the front end functions of both control centers and supports a consolidation of control positions which effectively reduces operations cost. This paper defines that common concept and describes the progress that has been made in development of the Consolidated Communications Facility (CCF) during the past year.

  5. Comparison of a center and off-center BWR control rod drop accident

    SciTech Connect

    Cokinos, D.M.; Neogy, P.; Carew, J.F.

    1984-07-01

    A BWR control rod drop accident (RDA) induces a rapid core power transient involving strong neutronic/thermal-hydraulic coupling, which requires a detailed multi-dimensional spatial kinetics analysis. Typical two-dimensional (r,z) RDA calculations require that the dropped rod be a center rod, as a result of geometric limitations, while in three-dimensional (x,y,z) calculations the dropped rod is generally taken to be the center rod in order to allow a quarter-core representation and limit computer running times. However, for typical BWR core loadings, the highest worth rod is not necessarily the center rod and it is not known, a priori, what effect this difference in spatial location has on the RDA dynamics. In order to evaluate the effects of this simplification, three-dimensional RAMONA-3B calculations have been performed for both a center and off-center control rod drop accident.

  6. Controlled environments alter nutrient content of soybeans

    1997-01-01

    Information about compositional changes in plants grown in controlled environments is essential for developing a safe, nutritious diet for a Controlled Ecological Life-Support System (CELSS). Information now is available for some CELSS candidate crops, but detailed information has been lacking for soybeans. To determine the effect of environment on macronutrient and mineral composition of soybeans, plants were grown both in the field and in a controlled environment where the hydroponic nutrient solution, photosynthetic flux (PPF), and CO_2 level were manipulated to achieve rapid growth rates. Plants were harvested at seed maturity, separated into discrete parts, and oven dried prior to chemical analysis. Plant material was analyzed for proximate composition (moisture, protein, lipid, ash, and carbohydrate), total nitrogen (N), nonprotein N (NPN), nitrate, minerals, amino acid composition, and total dietary fiber. The effect of environment on composition varied by cultivar and plant part. Chamber-grown plants generally exhibited the following characteristics compared with field-grown plants: 1) increased total N and protein N for all plant parts, 2) increased nitrate in leaves and stems but not in seeds, 3) increased lipids in seeds, and 4) decreased Ca:P ratio for stems, pods, and leaves. These trends are consistent with data for other CELSS crops. Total N, protein N, and amino acid contents for 350 ppm CO_2 and 1000 ppm CO_2 were similar for seeds, but protein N and amino acid contents for leaves were higher at 350 ppm CO_2 than at 1000 ppm CO_2. Total dietary fiber content of soybean leaves was higher with 350 ppm CO_2 than with 1000 ppm CO_2. Such data will help in selecting of crop species, cultivars, and growing conditions to ensure safe, nutritious diets for CELSS.

    Malloch, K

    1999-01-01

    Patient care executives are continually challenged to increase productivity without additional expense or negative effect on patient care quality. Identifying the optimal organizational set of circumstances that meets the needs of all stakeholders is a challenge for even the most dedicated and skilled executive. This article is a case study in which healthcare leaders intuitively believed in a healing environment and successfully implemented the organizational changes necessary to translate the essence of healing into their traditional organization. The experiences of seven executives within the organization provide critical information for organizations considering implementation of a healing model in traditional settings. Characteristics of a healing model, planning and implementation considerations, and the measurement of the outcomes are identified. In addition, the research methodology used to examine the relationship of healing model characteristics to selected organizational outcomes is described.

  10. Contemplating the plasmalemmal control center model

    NASA Technical Reports Server (NTRS)

    Pickard, B. G.

    1994-01-01

    An abundant epidermal mechanosensory calcium-selective ion channel appears able not only to detect mechanical stimuli such as those that initiate gravitropism but also to detect thermal, electrical, and various chemical stimuli. Because it responds to multimodal input with a second messenger output, this channel system seems likely to be an integrator that can engage in feedbacks with many other systems of the cell--and feedback is the hallmark of regulation. In general, the mechanical tension required for channel activation is likely transmitted from the relatively rigid cell wall to the plasma membrane system via linkage or adhesion sites that display antigenicities recognized by antibodies to animal beta-1 integrin, vitronectin, and fibronectin and which have mechanical connections to the cytoskeleton. Thus, functionally, leverage exerted against any given adhesion site will tend to control channels within a surrounding domain. Reactions initiated by passage of calcium ions through the channels could presumably be more effectively regulated if channels within the domains were somewhat clustered and if appropriate receptors, kinases, porters, pumps, and some key cytoskeletal anchoring sites were in turn clustered about them. Accumulating evidence suggests not only that activity of clusters of channels may contribute to control of cytoskeletal architecture and of regulatory protein function within their domain, but also that both a variety of regulatory proteins and components of the cortical cytoskeleton may contribute to control of channel activity. The emerging capabilities of electronic optical microscopy are well suited for resolving the spatial distributions of many of these cytoskeletal and regulatory molecules in living cells, and for following some of their behaviors as channels are stimulated to open and cytosolic calcium builds in their vicinity. Such microscopy, coupled with biochemical and physiological probing, should help to establish the nature of

    This paper describes a closed-loop control system for controlling the irradiance and spectral quality generated by fluorescent lamps in a controlled environment chamber. The 400 to 800 nm irradiance and the ratio of the red waveband (600 to 700 nm) to the far-red waveband (700 to 800 nm) were independently controlled and varied as functions of time. A suggested application is to investigate the possibility of synergistic effects of changing irradiance levels and changing spectral distributions on photoperiodism and photomorphogenesis.

    Blanc, P D; Kearney, T E; Olson, K R

    1995-01-01

    We assessed fatal drug overdose and poisoning case surveillance by a regional poison control center, comparing it with medical examiner determinations of death by poisoning over the same 2-year period and from the same catchment area. We studied 358 fatal cases of poisoning or drug overdose reported by a medical examiner and 10 fatal cases of poisoning or drug overdose reported by a poison control center, analyzing demographics and other case-associated factors with with possible successful poison control center case surveillance. Of the medical examiner cases, 245 (68%) were prehospital deaths. Of the remaining 113 emergency department or hospital cases, only 5 (4.4%) were also reported to the poison control center. Compared with cases involving illicit drugs, other narcotics, and sedative drugs, those that involved other prescription drugs (relative odds, 30.6; 95% confidence interval, 2.7 to 351) and over-the-counter products and other substances (odds ratio, 18.9; 95% confidence interval, 1.4 to 257) were significantly more likely to be reported to the poison control center. Most fatal cases of poisoning and drug overdose are not detected through poison control center surveillance. For prevention and treatment, health planners and policy makers should recognize the implications of case underreporting. PMID:7618309

  18. User-centered virtual environment assessment and design for cognitive rehabilitation applications

    NASA Astrophysics Data System (ADS)

    Fidopiastis, Cali Michael

    Virtual environment (VE) design for cognitive rehabilitation necessitates a new methodology to ensure the validity of the resulting rehabilitation assessment. We propose that benchmarking the VE system technology utilizing a user-centered approach should precede the VE construction. Further, user performance baselines should be measured throughout testing as a control for adaptive effects that may confound the metrics chosen to evaluate the rehabilitation treatment. To support these claims we present data obtained from two modules of a user-centered head-mounted display (HMD) assessment battery, specifically resolution visual acuity and stereoacuity. Resolution visual acuity and stereoacuity assessments provide information about the image quality achieved by an HMD based upon its unique system parameters. When applying a user-centered approach, we were able to quantify limitations in the VE system components (e.g., low microdisplay resolution) and separately point to user characteristics (e.g., changes in dark focus) that may introduce error in the evaluation of VE based rehabilitation protocols. Based on these results, we provide guidelines for calibrating and benchmarking HMDs. In addition, we discuss potential extensions of the assessment to address higher level usability issues. We intend to test the proposed framework within the Human Experience Modeler (HEM), a testbed created at the University of Central Florida to evaluate technologies that may enhance cognitive rehabilitation effectiveness. Preliminary results of a feasibility pilot study conducted with a memory impaired participant showed that the HEM provides the control and repeatability needed to conduct such technology comparisons. Further, the HEM affords the opportunity to integrate new brain imaging technologies (i.e., functional Near Infrared Imaging) to evaluate brain plasticity associated with VE based cognitive rehabilitation.

  19. Control of fluidic environments by mushrooms

    NASA Astrophysics Data System (ADS)

    2013-11-01

    Thousands of fungal species rely on mushrooms for spore release and dispersal. Long distance spore dispersal by wind is instrumental to maintain genetic diversity and to the spread of pathogenic species. The conventional view is that fungi enjoy little control over the mechanism of dispersal. A spore falling from the mushroom cap can only hope to be picked up by a favorable airflow and carried away from the gap between the mushroom cap and the ground. We show that fungi actively manipulate their local fluidic environment by altering the buoyancy of the air surrounding the mushroom using a combination of water vapor and active cooling. This manipulation allows spore escape and dispersal from caps that may be spaced a few millimeters above the ground, or apart from each other. Through high speed videography, scaling analysis and indirect measurements, we reveal the fluid mechanics of spore escape, and how they are controlled by the biophysical properties of the mushroom.

  20. Candidate Species Selection and Controlled Environment Injuries

    NASA Technical Reports Server (NTRS)

    Tibbitts, T. W.

    1982-01-01

    Research was undertaken to attempt to identify the causal agents for intumescences that develop on many different species of plants in controlled environments. Concentration and filtration procedures were not successful in identifying any particular compounds. The injury was found to develop, even though the atmosphere for the plants is filtered through activated charcoal, potassium permanganate, or is subjected to catalytic combustion at 450 C. Thus, the causal agent is apparently either an oxidized compound or specific element, or the result of some unrecognized variation in physical conditions around the plants. The research has demonstrated that the injury is controlled to a significant extent by temperature. Growing temperatures of 20 degrees and 25 degrees C resulted in serious injury on plants, but temperatures of 30 C resulted in very little injury.

    A system is provided to control the environment experienced by a child in a child safety seat. Each of a plurality of thermoelectric elements is individually controllable to be one of heated and cooled relative to an ambient temperature. A first portion of the thermoelectric elements are positioned on the child safety seat such that a child sitting therein is positioned thereover. A ventilator coupled to the child safety seat moves air past a second portion of the thermoelectric elements and filters the air moved therepast. One or more jets coupled to the ventilator receive the filtered air. Each jet is coupled to the child safety seat and can be positioned to direct the heated/cooled filtered air to the vicinity of the head of the child sitting in the child safety seat.

    McCormick, Bonnie Day

    The purpose of this study is to determine the effectiveness of the revision of an undergraduate biology course to meet the standards set forth by current science education reform documents. This course was revised by a collaborate team at a small, religious, liberal arts university located in an urban area of South Texas. This institution is a Hispanic serving institution where the majority of students are Hispanic. The female population of this institution is approximately 70 percent. The course was revised to meet teaching standards called for in the National Science Education Standards. The guiding principle was to use an instructional model that was based on constructivist theories of learning. The lecture and laboratory sections of the course were combined into a class that met two days a week for three hours. A learner-centered instructional model based on learning cycles and the 5E model were used to organize instruction. Three sections of the experimental course were compared to three control sections that were taught in a traditional format of a three-hour lecture with a separate lab. Instruments that measured classroom learning environment, achievement, and attitude toward science were given at the beginning and conclusion of the course. Qualitative data was gathered from a questionnaire, university course evaluations, and student portfolios. Results of the learning environment survey found that two sections of the control class used some active learning within the context of the traditional lecture. These sections were analyzed as a modified lecture and the other control section as the traditional lecture. The experimental sections were the integrated sections. Subjects in the traditional and integrated sections scored higher on the content knowledge test than those in the modified section. This suggests that the integrated course was as successful as the traditional method in acquisition of content knowledge. Subjects the integrated course and the

    2003-01-01

    This study investigated pediatric pain control practices in North American Burn Centers using a mail-in survey. Questions were asked regarding pain control practices, pain assessment methods, and perceived treatment efficacy for inpatients and outpatients in four age groups. Eighty-two centers responded with 111 surveys. Intravenous morphine was the most frequently used analgesic for wound care pain. The most common background pain medications were intravenous morphine, acetaminophen with codeine, and acetaminophen alone. The use of long-acting medications increased with increasing age. Additional areas reported in the text include nonpharmacologic and pharmacologic adjuvants, treatment of itching, pain assessment, outpatient pain management, and efficacy of pain control and assessment practices. There have been great advances in pediatric burn pain control and assessment in recent years, but room for improvement remains. This study provides a basis for evaluation and comparison among burn centers. It further highlights areas that may warrant additional study and intervention.

    A new generation of Mini All-purpose Satellite Control Centers (MASCC) has been developed by CNES (F). They turn out to be easily adaptable to different kinds of satellites, both Low Earth Orbital or Geostationary. The features of MASCC allow both standard satellite control activities, and checking of passengers experiments hosted on a space platform. In the different environments in which it may be used, MASCC provides standard broadcasting of telemetry parameters on animated synoptics (curves, bar graphs, alphanumeric displays, ...), which turns out to be a very useful and ergonomic medium for operational teams or satellite specialists. Special care has been taken during the MASCC development about two points: - automation of all routine tasks, allowing automated operation, and limiting human commitment to system supervision and decision making, - software adaptability. To reach these two main objectives, the MASCC design provides:(1) a simple, robust and flexible hardware architecture, based on powerful distributed workstations; and (2) a table-driven software architecture, easily adapted to various operational needs. Satellite characteristics are described in a central Data Base. Hence, the processing of telemetry and commands is largely independent from the satellite itself. In order to validate these capabilities, the MASCC has been customized to several types of satellites and orbital platforms: (1) SPOT4, the French new generation of remote sensing satellites; (2) TELECOM2, the French geostationary TV and telecommunication satellite; and (3) MIR, the Russian orbital platform. MASCC development has been completed by the third quarter of 1993. This paper will provide first a description of the MASCC basic functions, of its hardware and software design. It will then detail the increased automation capability, along with the easy adaptation of the MASCC to new satellites with minimal software modifications.

    2002-01-01

    Marshall Space Flight Center has developed world-class space environmental effects testing facilities to simulate the space environment. The combined environmental effects test system exposes temperature-controlled samples to simultaneous protons, high- and low-energy electrons, vacuum ultraviolet (VUV) radiation, and near-ultraviolet (NUV) radiation. Separate chambers for studying the effects of NUV and VUV at elevated temperatures are also available. The Atomic Oxygen Beam Facility exposes samples to atomic oxygen of 5 eV energy to simulate low-Earth orbit (LEO). The LEO space plasma simulators are used to study current collection to biased spacecraft surfaces, arcing from insulators and electrical conductivity of materials. Plasma propulsion techniques are analyzed using the Marshall magnetic mirror system. The micro light gas gun simulates micrometeoroid and space debris impacts. Candidate materials and hardware for spacecraft can be evaluated for durability in the space environment with a variety of analytical techniques. Mass, solar absorptance, infrared emittance, transmission, reflectance, bidirectional reflectance distribution function, and surface morphology characterization can be performed. The data from the space environmental effects testing facilities, combined with analytical results from flight experiments, enable the Environmental Effects Group to determine optimum materials for use on spacecraft.

    Virtual reality exposure therapy has been proposed as a viable alternative in the treatment of anxiety disorders, including social anxiety disorder. Therapists could benefit from extensive control of anxiety eliciting stimuli during virtual exposure. Two stimuli controls are studied in this study: the social dialogue situation, and the dialogue feedback responses (negative or positive) between a human and a virtual character. In the first study, 16 participants were exposed in three virtual reality scenarios: a neutral virtual world, blind date scenario, and job interview scenario. Results showed a significant difference between the three virtual scenarios in the level of self-reported anxiety and heart rate. In the second study, 24 participants were exposed to a job interview scenario in a virtual environment where the ratio between negative and positive dialogue feedback responses of a virtual character was systematically varied on-the-fly. Results yielded that within a dialogue the more positive dialogue feedback resulted in less self-reported anxiety, lower heart rate, and longer answers, while more negative dialogue feedback of the virtual character resulted in the opposite. The correlations between on the one hand the dialogue stressor ratio and on the other hand the means of SUD score, heart rate and audio length in the eight dialogue conditions showed a strong relationship: r(6) = 0.91, p = 0.002; r(6) = 0.76, p = 0.028 and r(6) = −0.94, p = 0.001 respectively. Furthermore, more anticipatory anxiety reported before exposure was found to coincide with more self-reported anxiety, and shorter answers during the virtual exposure. These results demonstrate that social dialogues in a virtual environment can be effectively manipulated for therapeutic purposes. PMID:24671006

Results yielded that within a dialogue the more positive dialogue feedback resulted in less self-reported anxiety, lower heart rate, and longer answers, while more negative dialogue feedback of the virtual character resulted in the opposite. The correlations between on the one hand the dialogue stressor ratio and on the other hand the means of SUD score, heart rate and audio length in the eight dialogue conditions showed a strong relationship: r(6) = 0.91, p = 0.002; r(6) = 0.76, p = 0.028 and r(6) = -0.94, p = 0.001 respectively. Furthermore, more anticipatory anxiety reported before exposure was found to coincide with more self-reported anxiety, and shorter answers during the virtual exposure. These results demonstrate that social dialogues in a virtual environment can be effectively manipulated for therapeutic purposes.

    The majority of children in the United States attend out-of-home child care. However, little is known about the nutritional quality of foods served and the mealtime environments. We assessed 96 child care centers over one full day using a researcher-administered structured observation and document review. We focused on eight nutrition domains: (1) fruits and vegetables, (2) whole grains, (3) high-sugar, high-salt, and high-fat foods, (4) beverages, (5) food availability and service, (6) staff behaviors, (7) training and education, and (8) policies. We computed daily means and frequencies for each domain. Seventy-five percent of centers participated in the Child and Adult Care Food Program, indicating they served low-income children. Centers enrolled 66 children on average; 60% were white, 28% were black, 4% were Native American, and 8% identified as mixed race. On the day of observation, seven centers did not serve a fruit and 15 did not serve a vegetable. Eighty centers served a high-sugar or high-salt food and 84 did not serve any whole grains. Five centers did not provide water indoors to children, 22 served juice twice, and 50 served whole milk. Seventeen centers had a vending machine on site visible to parents and children. Overall, children were served excessive juice, high-sugar and high-salt snack foods, and too much whole milk. Centers had room for improvement and could strive to serve more nutritious foods and create healthier mealtime environments for children.

  1. Access control mechanisms for distributed healthcare environments.

    Sergl-Pommerening, Marita

    2004-01-01

    Today's IT-infrastructure provides more and more possibilities to share electronic patient data across several healthcare organizations and hospital departments. A strong requirement is sufficient data protection and security measures complying with the medical confidentiality and the data protection laws of each state or country like the European directive on data protection or the U.S. HIPAA privacy rule. In essence, the access control mechanisms and authorization structures of information systems must be able to realize the Need-To-Access principle. This principle can be understood as a set of context-sensitive access rules, regarding the patient's path across the organizations. The access control mechanisms of today's health information systems do not sufficiently satisfy this requirement, because information about participation of persons or organizations is not available within each system in a distributed environment. This problem could be solved by appropriate security services. The CORBA healthcare domain standard contains such a service for obtaining authorization decisions and administrating access decision policies (RAD). At the university hospital of Mainz we have developed an access control system (MACS), which includes the main functionality of the RAD specification and the access control logic that is needed for such a service. The basic design principles of our approach are role-based authorization, user rights with static and dynamic authorization data, context rules and the separation of three cooperating servers that provide up-to-date knowledge about users, roles and responsibilities. This paper introduces the design principles and the system design and critically evaluates the concepts based on practical experience.

    The Mission Control Center (MCC), located at the Johnson Space Center near Houston, Texas, is the primary point of control and monitoring for National Space Transportation System (NSTS) flight activities. NSTS flight managers monitor and command spacecraft from one of two Flight Control Rooms (FCR). Each FCR is equipped with five large screen displays for group dissemination of spacecraft system status and vehicle position relative to Earth geography. The primary or center screen display is ten feet in height and twenty feet in width. The secondary or side screens are seven and one-hald feet high and ten feet wide. The center screen projection system is exhibiting high maintenance costs and is considered to be in wear-out phase. The replacement of the large center screen displays at the MCC is complicated by the unique requirements of the Flight Controller user. These requirements demand a very high performance, multiple color projection system capable of the display of high resolution text, graphics and images produced in near real time. The current system to be replaced, the replacement system requirements, the efforts necessary to procure the major element of this system (the projector) for the government, and how the new capabilities are to be integrated into the existing MCC operational configuration are discussed.

  4. Development of a Set of Indicators to Evaluate Injury Control Research Centers.

    Few methods have been defined for evaluating the individual and collective impacts of academic research centers. In this project, with input from injury center directors, we systematically defined indicators to assess the progress and contributions of individual Injury Control Research Centers (ICRCs) and, ultimately, to monitor progress of the overall injury center program. We used several methods of deriving a list of recommended priority and supplemental indicators. This included published literature review, telephone interviews with selected federal agency staff, an e-mail survey of injury center directors, an e-mail survey of staff at the Centers for Disease Control and Prevention, a two-stage Delphi process (e-mailed), and an in-person focus group with injury center directors. We derived the final indicators from an analysis of ratings of potential indicators by center directors and CDC staff. We also examined qualitative responses to open-ended items that address conceptual and implementation issues. All currently funded ICRCs participated in at least one part of the process, resulting in a list of 27 primary indicators (some with subcomponents), 31 supplemental indicators, and multiple suggestions for using the indicators. Our results support an approach that combines standardized definitions and quantifiable indicators with qualitative reporting, which allows consideration of center distinctions and priorities. The center directors urged caution in using the indicators, given funding constraints and recognition of unique institutional environments. While focused on injury research centers, we suggest these indicators also may be useful to academic research centers of other types. © The Author(s) 2014.

    The municipal electric utility of Empresas Publicas de Medellin (EPM) in Medellin, Colombia, has completed the installation and testing of their new control center. These facilities, which include all the functions expected from a modern control center, were implemented through carefully monitored and executed project stages, which are described in this article. EPM generates and transmits 1400 MW of exclusively hydroelectric energy to their service territory of the city of Medellin and nine neighboring cities and 77 smaller cities. The EPM system load ranges from 400 MW to 1200 MW.

  6. History and applications in controlled environments

    The widespread application of electric (often called artificial) light in greenhouses, growing rooms, and plant growth chambers would presuppose that the role of phytochrome would be considered in the selection and use of such lighting systems. Part of the problem is that many students, and indeed an unfortunate number of senior scientists, seem to regard phytochrome as a laboratory phenomenon without much application in the real world. They simply have not grasped the concept that phytochrome is functioning through all stages of plant development, wherever plants are grown. It is certainly true, as Meijer (1971) stated, that one cannot compare experimental results obtained under very strict laboratory conditions with plant irradiation in glasshouses and in growth rooms. For example, the action spectrum for flowering of the long-day plant, Hyoscyamus niger, clearly shows that red radiation is the most efficient portion of the spectrum for promoting flower initiation, but in practical photoperiod control red or fluorescent lamps do not promote flowering nearly as well as the mixture of red and far-red in incandescent lamps. Nevertheless, much evidence exists that documents phytochrome control of plant growth and development in controlled environments and under natural conditions. When Karl Norris developed the first practical portable spectroradiometer about 1962 some of the first measurements were to determine the red/far-red ratios under tree canopies. These measurements showed clearly the predominance of far-red in the understory and suggested that far-red was contributing to the elongation exhibited by many species growing in the shade, and possibly was a factor in the induction of light requirements in seeds. Subsequently we used Catalpa leaves as far-red filters to make light-insensitive lettuce seed light requiring.

    Learning environments overtly or implicitly address patient-centered values and have been the focus of research for more than 40 years, often in studies about the "hidden curriculum." However, many of these studies occurred at single medical schools and used time-intensive ethnographic methods. This field of inquiry lacks survey methods and information about how learning environments differ across medical schools. To examine patient-centered characteristics of learning environments at 9 U.S. medical schools. Cross-sectional internet-based survey. Eight-hundred and twenty-three third- and fourth-year medical students in the classes of 2002 and 2003. We measured the patient-centeredness of learning environments with the Communication, Curriculum, and Culture (C3) Instrument, a 29-item validated measure that characterizes the degree to which a medical school's environment fosters patient-centered care. The C3 Instrument contains 3 content areas (role modeling, students' experiences, and support for students' patient-centered behaviors), and is designed to measure these areas independent of respondents' attitudes about patient-centered care. We also collected demographic and attitudinal information from respondents. The variability of C3 scores across schools in each of the 3 content areas of the instrument was striking and statistically significant (P values ranged from .001 to .004). In addition, the patterns of scores on the 3 content areas differed from school to school. The 9 schools demonstrated unique and different learning environments both in terms of magnitude and patterns of characteristics. Further multiinstitutional study of hidden curricula is needed to further establish the degree of variability that exists, and to assist educators in making informed choices about how to intervene at their own schools.

  17. Earth Rings for Planetary Environment Control

    NASA Astrophysics Data System (ADS)

    Pearson, Jerome; Oldson, John; Levin, Eugene; Carroll, Joseph

    2002-01-01

    For most of its past, large parts of the Earth have experienced subtropical climates, with high sea levels and no polar icecaps. This warmer environment was punctuated 570, 280, and 3 million years ago with periods of glaciation that covered temperate regions with thick ice for millions of years. At the end of the current ice age, a warmer climate could flood coastal cities, even without human-caused global warming. In addition, asteroids bombard the Earth periodically, with impacts large enough to destroy most life on Earth, and the sun is warming inexorably. This paper proposes a concept to solve these problems simultaneously, by creating an artificial planetary ring about the Earth to shade it. Past proposals for space climate control have depended on gigantic engineering structures launched from Earth and placed in Earth orbit or at the Earth-Sun L1 libration point, requiring fabrication, large launch masses and expense, constant control, and repair. Our solution is to begin by using lunar material, and then mine and remove Earth-orbit-crossing asteroids and discard the tailings into Earth orbit, to form a broad, flat ring like those of Saturn. This solution is evaluated and compared with other alternatives. Such ring systems can persist for thousands of years, and can be maintained by shepherding satellites or by continual replenishment from new asteroids to replace the edges of the ring lost by diffusion. An Earth ring at R = 1.3-1.83 RE would shade only the equatorial regions, moderating climate extremes, and could reverse a century of global warming. It could also absorb particles from the radiation belts, making trips to high Earth orbit and GEO safer for humans and for electronics. It would also light the night many times as bright as the full moon. A preliminary design of the ring is developed, including its location, mass, composition, stability, and timescale required. A one-dimensional climate model is used to evaluate the Earth ring performance

  20. Future Concepts for Realtime Data Interfaces for Control Centers

    NASA Technical Reports Server (NTRS)

    Kearney, Mike W., III

    2004-01-01

    Existing methods of exchanging realtime data between the major control centers in the International Space Station program have resulted in a patchwork of local formats being imposed on each Mission Control Center. This puts the burden on a data customer to comply with the proprietary data formats of each data supplier. This has increased the cost and complexity for each participant, limited access to mission data and hampered the development of efficient and flexible operations concepts. Ideally, a universal format should be promoted in the industry to prevent the unnecessary burden of each center processing a different data format standard for every external interface with another center. With the broad acceptance of XML and other conventions used in other industries, it is now time for the Aerospace industry to fully engage and establish such a standard. This paper will briefly consider the components that would be required by such a standard (XML schema, data dictionaries, etc.) in order to accomplish the goal of a universal low-cost interface, and acquire broad industry acceptance. We will then examine current approaches being developed by standards bodies and other groups. The current state of CCSDS panel work will be reviewed, with a survey of the degree of industry acceptance. Other widely accepted commercial approaches will be considered, sometimes complimentary to the standards work, but sometimes not. The question is whether de facto industry standards are in concert with, or in conflict with the direction of the standards bodies. And given that state of affairs, the author will consider whether a new program establishing its Mission Control Center should implement a data interface based on those standards. The author proposes that broad industry support to unify the various efforts will enable collaboration between control centers and space programs to a wider degree than is currently available. This will reduce the cost for programs to provide realtime

    Spacelab-3 launched aboard STS-51B, with the major science objective being to perform engineering tests on two new facilities: the rodent animal holding facility and the primate animal holding facility. In addition, scientists observed the animals to obtain first hand knowledge of the effects of launch and reentry stresses and behavior. The need for suitable animal housing to support research in space led to the development of the Research Animal Holding Facility at the Ames Research Center. Scientists often study animals to find clues to human physiology and behavior. Rats, insects, and microorganisms had already been studied aboard the Shuttle on previous missions. On Spacelab-3, scientists had a chance to observe a large number of animals living in space in a specially designed and independently controlled housing facility. Marshall Space Flight Center (MSFC) had management responsibility for the Spacelab-3 mission. This photograph depicts activities during the mission at the Huntsville Operations Support Center (HOSC) Spacelab Payload Operations Control Center (SL POCC) at MSFC.

    Spacelab-3 launched aboard STS-51B, with the major science objective being to perform engineering tests on two new facilities: the rodent animal holding facility and the primate animal holding facility. In addition, scientists observed the animals to obtain first hand knowledge of the effects of launch and reentry stresses and behavior. The need for suitable animal housing to support research in space led to the development of the Research Animal Holding Facility at the Ames Research Center. Scientists often study animals to find clues to human physiology and behavior. Rats, insects, and microorganisms had already been studied aboard the Shuttle on previous missions. On Spacelab-3, scientists had a chance to observe a large number of animals living in space in a specially designed and independently controlled housing facility. Marshall Space Flight Center (MSFC) had management responsibility for the Spacelab 3 mission. This photograph depicts activities during the mission at the Huntsville Operations Support Center (HOSC) Spacelab Payload Operations Control Center (SL POCC) at MSFC.

    The construction of data center network by applying SDN technology has become a hot research topic. The SDN architecture has innovatively separated the control plane from the data plane which makes the network more software-oriented and agile. Moreover, it provides virtual multi-tenancy, effective scheduling resources and centralized control strategies to meet the demand for cloud computing data center. However, the explosion of network information is facing severe challenges for SDN controller. The flow storage and lookup mechanisms based on TCAM device have led to the restriction of scalability, high cost and energy consumption. In view of this, a source-controlled data center network (SCDCN) model is proposed herein. The SCDCN model applies a new type of source routing address named the vector address (VA) as the packet-switching label. The VA completely defines the communication path and the data forwarding process can be finished solely relying on VA. There are four advantages in the SCDCN architecture. 1) The model adopts hierarchical multi-controllers and abstracts large-scale data center network into some small network domains that has solved the restriction for the processing ability of single controller and reduced the computational complexity. 2) Vector switches (VS) developed in the core network no longer apply TCAM for table storage and lookup that has significantly cut down the cost and complexity for switches. Meanwhile, the problem of scalability can be solved effectively. 3) The SCDCN model simplifies the establishment process for new flows and there is no need to download flow tables to VS. The amount of control signaling consumed when establishing new flows can be significantly decreased. 4) We design the VS on the NetFPGA platform. The statistical results show that the hardware resource consumption in a VS is about 27% of that in an OFS.

    Determine the relationship between obesogenic characteristics of childcare and child adiposity in tribally-affiliated centers in Oklahoma. The two-day Environment and Policy Assessment and Observation (EPAO) included a total environment (TE), nutrition (N), and physical activity (PA) score and took place in 11 centers across Oklahoma. Eighty-two preschool children (3-5 years) participated. Child height and weight were measured and overweight status (≥ 85th percentile for age and sex) was determined. Regression models, fit using Generalized Estimating Equations methodology to account for clustering by center were used and adjusted for center characteristics. Participants were 3.8 (0.8) years old, 55% male, 67% American Indian (AI) and 38% overweight. A healthier TE and PA was associated with a reduced odds of overweight, which remained significant after adjusting for some center characteristics, but not all. A healthier TE, N, and PA was associated with lower BMI percentile, which remained significant after some center-level adjustments, but not all. Lower sedentary opportunity and sedentary time were no longer associated with reduced odds of overweight following adjustment. Lower opportunity for high sugar and high fat foods and minutes of active play were associated with reduced odds of overweight in some adjusted models. Collectively unadjusted and adjusted models demonstrate that some aspects of a healthier childcare center environment are associated with reduced odds of overweight and lower BMI percentile in preschool children attending tribally-affiliated childcare in Oklahoma. Future research should examine the association of childcare and health behaviors and further explore the role of potential confounders.

    The American Association of Poison Control Centers (AAPCC; http://www.aapcc.org) maintains the national database of information logged by the country's 61 Poison Control Centers (PCCs). Case records in this database are from self-reported calls: they reflect only information provided when the public or healthcare professionals report an actual or potential exposure to a substance (e.g., an ingestion, inhalation, or topical exposure.), or request information/educational materials. Exposures do not necessarily represent a poisoning or overdose. The AAPCC is not able to completely verify the accuracy of every report made to member centers. Additional exposures may go unreported to PCCs, and data referenced from the AAPCC should not be construed to represent the complete incidence of national exposures to any substance(s). U.S. Poison Centers make possible the compilation and reporting of this report through their staffs' meticulous documentation of each case using standardized definitions and compatible computer systems. The 61 participating poison centers in 2005 are: Regional Poison Control Center, Birmingham, AL; Alabama Poison Center, Tuscaloosa, AL; Arizona Poison and Drug Information Center, Tucson, AZ; Banner Poison Control Center, Phoenix, AZ; Arkansas Poison and Drug Information Center, Little Rock, AK; California Poison Control System-Fresno/Madera Division, CA; California Poison Control System-Sacramento Division, CA; California Poison Control System-San Diego Division, CA; California Poison Control System-San Francisco Division, CA; Rocky Mountain Poison and Drug Center, Denver, CO; Connecticut Poison Control Center, Farmington, CT; National Capital Poison Center, Washington, DC; Florida Poison Information Center, Tampa, FL; Florida Poison Information Center, Jacksonville, FL; Florida Poison Information Center, Miami, FL; Georgia Poison Center, Atlanta, GA; Illinois Poison Center, Chicago, IL; Indiana

    The article deals with a pilot investigation into the audio communication of cosmonauts with ground controllers. The purpose was to verify in space flight the patterns and trends revealed in model tests of intergroup communication, and to pinpoint the signature of multinational crew communication with 2 national mission control centers (MCCs). The investigation employed authors' content-analysis adapted to the scenario of long-duration mission. The investigation resulted in a phenomenon of double-loop ground-orbit communication, divergence, difference in opinion predictable from the concept formulated by G.T.Beregovoi. Also, there was a notable difference of expressions used by controllers of 2 MCCs.

    The ultrathin transition metal dichalcogenides (TMDs) have emerged as promising materials for various applications using two dimensional semiconductors. They have attracted increasing attention due to their unique optical properties originate from neutral and charged excitons. In this paper, we study the strong localization of exciton center-of-mass motion within random potential fluctuations caused by the monolayer defects. Here, we report negatively charged exciton formation in monolayer TMDs, notably tungsten disulfide WS2. Our theory is based on an effective mass model of neutral and charged excitons, parameterized by ab-initio calculations. Taking into the account the strong correlation between the monolayer WS2 and the surrounding dielectric environment, our theoretical results are in good agreement with one-photon photoluminescence (PL) and reflectivity measurements. We also show that the exciton state with p-symmetry, experimentally observed by two-photon PL emission, is energetically below the 2s-state. We use the equilibrium mass action law, to quantify the relative weight of exciton and trion PL. We show that exciton and trion emission can be tuned and controlled by external parameters like temperature, pumping, and injection electrons. Finally, in comparison with experimental measurements, we show that exciton emission in monolayer tungsten dichalcogenides is substantially reduced. This feature suggests that free exciton can be trapped in disordered potential wells to form a localized exciton and therefore offers a route toward novel optical properties.

    A system which will provide real-time failure management support to the Space Station Freedom program is described. The system's use of a simplified form of model based reasoning qualifies it as an advanced automation system. However, it differs from most such systems in that it was designed from the outset to meet two sets of requirements. First, it must provide a useful increment to the fault management capabilities of the Johnson Space Center (JSC) Control Center Complex (CCC) Fault Detection Management system. Second, it must satisfy CCC operational environment constraints such as cost, computer resource requirements, verification, and validation, etc. The need to meet both requirement sets presents a much greater design challenge than would have been the case had functionality been the sole design consideration. The choice of technology, discussing aspects of that choice and the process for migrating it into the control center is overviewed.

    The management of patients from administrative admission through the orthopedic-surgical treatment to completion of the billing is complex. Additional challenges originate from the necessity to treat patients in both outpatient and inpatient departments and in more than one medical sector. A superior coordination is essential for a successful cooperation of the various procedures of controlling. The model of a medical controlling department as a service center with effective competence in the management of service and cost, functions as a successful solution to the problem. Central elements of a successful medical economical case management are a well-defined assignment of tasks and definitions of intersections, the integration of health professionals and administrative employees, the utilization of software for process control and the implementation of inlier controlling.

    Objectives We introduce and describe the Breast Cancer and the Environment Research Centers (BCERC), a research network with a transdisciplinary approach to elucidating the role of environmental factors in pubertal development as a window on breast cancer etiology. We describe the organization of four national centers integrated into the BCERC network. Data sources Investigators use a common conceptual framework based on multiple levels of biologic, behavioral, and social organization across the life span. The approach connects basic biologic studies with rodent models and tissue culture systems, a coordinated multicenter epidemiologic cohort study of prepubertal girls, and the integration of community members of breast cancer advocates as key members of the research team to comprise the network. Data extraction Relevant literature is reviewed that describes current knowledge across levels of organization. Individual research questions and hypotheses in BCERC are driven by gaps in our knowledge that are presented at genetic, metabolic, cellular, individual, and environmental (physical and social) levels. Data synthesis As data collection on the cohort, animal experiments, and analyses proceed, results will be synthesized through a transdisciplinary approach. Conclusion Center investigators are addressing a large number of specific research questions related to early pubertal onset, which is an established risk factor for breast cancer. BCERC research findings aimed at the primary prevention of breast cancer will be disseminated to the scientific community and to the public by breast cancer advocates, who have been integral members of the research process from its inception.

    2004-01-01

    The Community Health Center Network measured the prevalence of glycemic control in diabetic patients at 7 community health centers as part of its clinical quality improvement program. A cross-sectional survey was carried out in a random sample of 1817 diabetic patients having 1 or more encounters from October 1, 2000 to September 30, 2001. Computerized laboratory results for hemoglobin A1c (HbA1c) tests were available for half the sample. Manual review of medical charts was carried out for the rest. The proportion of diabetic patients with 1 or more HbA1c tests in the measurement year was 91% (CI95%: 90-93%) and poor glycemic control (HbA1c > 9%) occurred in 27% (CIM%: 25-30%). The mean of the most recent test was 7.8%. The frequency of testing varied significantly by clinic from 79% to 94% and increased with the number of encounters. Poor glycemic control also varied significantly by clinic (17-48%) and was significantly better in females and older patients. Measures of glycemic control were not associated with ethnicity or insurance status in multivariate analyses. A high proportion of diabetic patients received appropriate care, and this care was not associated with ethnicity or insurance status. The data warehouse was an essential tool for the clinical quality improvement program.

    2014-01-01

    This lecture will provide an overview of the aircraft turbine engine control research at NASA (National Aeronautics and Space Administration) Glenn Research Center (GRC). A brief introduction to the engine control problem is first provided with a description of the current state-of-the-art control law structure. A historical aspect of engine control development since the 1940s is then provided with a special emphasis on the contributions of GRC. The traditional engine control problem has been to provide a means to safely transition the engine from one steady-state operating point to another based on the pilot throttle inputs. With the increased emphasis on aircraft safety, enhanced performance and affordability, and the need to reduce the environmental impact of aircraft, there are many new challenges being faced by the designers of aircraft propulsion systems. The Controls and Dynamics Branch (CDB) at GRC is leading and participating in various projects in partnership with other organizations within GRC and across NASA, other government agencies, the U.S. aerospace industry, and academia to develop advanced propulsion controls and diagnostics technologies that will help meet the challenging goals of NASA programs under the Aeronautics Research Mission. The second part of the lecture provides an overview of the various CDB technology development activities in aircraft engine control and diagnostics, both current and some accomplished in the recent past. The motivation for each of the research efforts, the research approach, technical challenges and the key progress to date are summarized. The technologies to be discussed include system level engine control concepts, gas path diagnostics, active component control, and distributed engine control architecture. The lecture will end with a futuristic perspective of how the various current technology developments will lead to an Intelligent and Autonomous Propulsion System requiring none to very minimum pilot interface

    Poison control center data are used in research and surveillance. Due to the large volume of information, these efforts are dependent on data being recorded in machine readable format. However, poison center records include non-machine readable text fields and machine readable coded fields, some of which are duplicative. Duplicating this data increases the chance of inaccurate/incomplete coding. For surveillance efforts to be effective, coding should be complete and accurate. Investigators identified a convenience sample of 964 records and reviewed the substance code determining if it matched its text field. They also reviewed the coded clinical effects and treatments determining if they matched the notes text field. The substance code matched its text field for 91.4% of the substances. The clinical effects and treatments codes matched their text field for 72.6% and 82.4% of occurrences respectively. This under-reporting of clinical effects and treatments has surveillance and public health implications.

    1997-07-01

    Operations and maintenance continued this month at the Electric Power Research Institute`s (EPRI`s) Environmental Control Technology Center (ECTC). Testing for the month involved the Dry Sorbent Injection (DST) test block with the Carbon Injection System. The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit, the 0.4 MW Mini-Pilot Wet Scrubber, and the 4.0 MW Pilot Wet Scrubber remained idle this month in a cold-standby mode and were inspected regularly. These units remain available for testing as future project work is identified. The 1990 Clean Air Act Amendments have required that the Environmental Protection Agency (EPA) assess the health risks and environmental effects associated with air toxic emissions (primarily mercury) from fossil-fuel fired utility boilers. EPRI has sponsored research on environmental mercury since 1983 to determine the factors that may influence human health, and to determine the role of electric power generating stations in contributing to those factors. Over the last four years, EPRI`s Environmental Control Technology Center (ECTC) has conducted EPRI and DOE sponsored testing to develop and demonstrate appropriate measurement methods and control technologies for power plant atmospheric mercury emissions. Building upon the experience and expertise of the EPRI ECTC, a test program was initiated at the Center in July to further evaluate dry sorbent-based injection technologies upstream of a cold-side ESP for mercury control, and to determine the effects of such sorbents on ESP performance. The results from this program will be compared to the results from previous DOE/EPRI demonstrations, and to other ongoing programs. The primary objectives of this test program are to: (1) Determine the levels of mercury removal achievable by dry sorbent injection upstream of an electrostatic precipitator (ESP). The process parameters to be investigated include sorbent residence time, sorbent type, sorbent size, sorbent loading, and flue gas

    The EVA Physiology, Systems and Performance (EPSP) Project is performing tests in different analog environments to understand human performance during Extravehicular Activity (EVA) with the aim of developing more safe and efficient systems for lunar exploration missions and the Constellation Program. The project is characterizing human EVA performance in studies using several test beds, including the underwater NASA Extreme Environment Mission Operations (NEEMO) and Neutral Buoyancy Laboratory (NBL) facilities, JSC fs Partial Gravity Simulator (POGO), and the NASA Reduced Gravity Office (RGO) parabolic flight aircraft. Using these varied testing environments, NASA can gain a more complete understanding of human performance issues related to EVA and the limitations of each testing environment. Tests are focused on identifying and understanding the EVA system factors that affect human performance such as center of gravity (CG), inertial mass, ground reaction forces (GRF), suit weight, and suit pressure. The test results will lead to the development of lunar EVA systems operations concepts and design requirements that optimize human performance and exploration capabilities. METHODS: Tests were conducted in the NBL and during NEEMO missions in the NOAA Aquarius Habitat. A reconfigurable back pack with repositionable mass was used to simulate Perfect, Low, Forward, High, Aft and NASA Baseline CG locations. Subjects performed simulated exploration tasks that included ambulation, kneel and recovery, rock pick-up, and shoveling. Testing using POGO, that simulates partial gravity via pneumatic weight offload system and a similar reconfigurable rig, is underway for a subset of the same tasks. Additionally, test trials are being performed on the RGO parabolic flight aircraft. Subject performance was assessed using a modified Cooper-Harper scale to assess operator compensation required to achieve desired performance. All CG locations are based on the assumption of a

    The paper summarizes Active Flow Control projects currently underway at the NASA Langley Research Center. Technology development is being pursued within a multidisciplinary, cooperative approach, involving the classical disciplines of fluid mechanics, structural mechanics, material science, acoustics, and stability and control theory. Complementing the companion papers in this session, the present paper will focus on projects that have the goal of extending the state-of-the-art in the measurement, prediction, and control of unsteady, nonlinear aerodynamics. Toward this goal, innovative actuators, micro and macro sensors, and control strategies are considered for high payoff flow control applications. The target payoffs are outlined within each section below. Validation of the approaches range from bench-top experiments to wind-tunnel experiments to flight tests. Obtaining correlations for future actuator and sensor designs are implicit in the discussion. The products of the demonstration projects and design tool development from the fundamental NASA R&D level technology will then be transferred to the Applied Research components within NASA, DOD, and US Industry.

    To successfully operate a photovoltaic (PV) array system in space requires planning and testing to account for the effects of the space environment. It is critical to understand space environment interactions not only on the PV components, but also the array substrate materials, wiring harnesses, connectors, and protection circuitry (e.g. blocking diodes). Key elements of the space environment which must be accounted for in a PV system design include: Solar Photon Radiation, Charged Particle Radiation, Plasma, and Thermal Cycling. While solar photon radiation is central to generating power in PV systems, the complete spectrum includes short wavelength ultraviolet components, which photo-ionize materials, as well as long wavelength infrared which heat materials. High energy electron radiation has been demonstrated to significantly reduce the output power of III-V type PV cells; and proton radiation damages material surfaces - often impacting coverglasses and antireflective coatings. Plasma environments influence electrostatic charging of PV array materials, and must be understood to ensure that long duration arcs do not form and potentially destroy PV cells. Thermal cycling impacts all components on a PV array by inducing stresses due to thermal expansion and contraction. Given such demanding environments, and the complexity of structures and materials that form a PV array system, mission success can only be ensured through realistic testing in the laboratory. NASA's Marshall Space Flight Center has developed a broad space environment test capability to allow PV array designers and manufacturers to verify their system's integrity and avoid costly on-orbit failures. The Marshall Space Flight Center test capabilities are available to government, commercial, and university customers. Test solutions are tailored to meet the customer's needs, and can include performance assessments, such as flash testing in the case of PV cells.

    2007-10-01

    Eszopiclone is a nonbenzodiazepine hypnotic for the treatment of insomnia and classified as schedule IV controlled substance. Limited information exists on eszopiclone ingestions reported to poison control centers. The distribution of eszopiclone ingestions reported to Texas poison control centers during 2005-2006 was determined for various factors. In addition, triage guidelines for the management of such ingestions were drafted. Of 525 total eszopiclone ingestions, 259 involved coingestants. Of coingestant cases, 78.8% involved suspected attempted suicide and 90.7% were managed at a healthcare facility. Of 266 ingestions of eszopiclone alone, 40.2% were suspected attempted suicide and 62.0% were managed at a healthcare facility. A final medical outcome and dose ingested were known for 60 ingestions of eszopiclone alone. The mean dose was 28.3 mg (range 0.3-210 mg). Ingestions of eszopiclone alone of < or =6 and >6 mg differed with respect to the proportion involving suspected attempted suicide (0.0% versus 64.7%), final medical outcome of minor or moderate effect (38.5% versus 67.6%) and management at a healthcare facility (34.6% versus 91.2%). Using 6 mg as a threshold dose for referral to a healthcare facility, 78% of cases not already at/en route to a healthcare facility were managed according drafted triage guidelines.

  8. The transition to massively parallel computing within a production environment at a DOE access center

    SciTech Connect

    McCoy, M.G.

    1993-04-01

    In contemplating the transition from sequential to MP computing, the National Energy Research Supercomputer Center (NERSC) is faced with the frictions inherent in the duality of its mission. There have been two goals, the first has been to provide a stable, serviceable, production environment to the user base, the second to bring the most capable early serial supercomputers to the Center to make possible the leading edge simulations. This seeming conundrum has in reality been a source of strength. The task of meeting both goals was faced before with the CRAY 1 which, as delivered, was all iron; so the problems associated with the advent of parallel computers are not entirely new, but they are serious. Current vector supercomputers, such as the C90, offer mature production environments, including software tools, a large applications base, and generality; these machines can be used to attack the spectrum of scientific applications by a large user base knowledgeable in programming techniques for this architecture. Parallel computers to date have offered less developed, even rudimentary, working environments, a sparse applications base, and forced specialization. They have been specialized in terms of programming models, and specialized in terms of the kinds of applications which would do well on the machines. Given this context, why do many service computer centers feel that now is the time to cease or slow the procurement of traditional vector supercomputers in favor of MP systems? What are some of the issues that NERSC must face to engineer a smooth transition? The answers to these questions are multifaceted and by no means completely clear. However, a route exists as a result of early efforts at the Laboratories combined with research within the HPCC Program. One can begin with an analysis of why the hardware and software appearing shortly should be made available to the mainstream, and then address what would be required in an initial production environment.

  9. Control of the aseptic processing environment.

    PubMed

    Frieben, W R

    1983-11-01

    Methods used by industry with applications to hospital pharmacy for maintaining an aseptic environment in production of sterile pharmaceutical products are discussed. A major source of product contamination is airborne microorganisms. The laminar-airflow workbench with a high-efficiency particulate air filter provides an ultraclean environment for preparation of sterile products. However, the workbench does not guarantee sterility of products and is not effective if not properly installed and maintained or if the operator uses poor aseptic technique. The laminar-airflow workbench should be tested for leaks, airflow velocity, and airflow patterns when installed, and the workbench should be checked periodically thereafter. The workbench should be placed in a cleanroom where traffic and air disturbances that might affect the laminar airflow are eliminated. A major source of airborne microbial contamination in cleanrooms is people. Personnel movement through an area and presence of personnel without lint-free, nonshedding protective garments increase the levels of microbial contaminants in an area. The transport of nonsterile products (bottles, boxes, paper products) into a cleanroom should be minimized. The cleanroom itself should be sanitized and should be immaculate. Microbial or particulate monitoring should be conducted in the cleanroom using a quantitative method, and corrective-action limits should be set. Hospital pharmacists should examine industrial sterile-processing techniques and apply them to the preparation of sterile products.

    Chamber A is the largest thermal vacuum chamber at the Johnson Space Center and is one of the largest space environment chambers in the world. The chamber is 19.8 m (65 ft) in diameter and 36.6 m (120 ft) tall and is equipped with cryogenic liquid nitrogen panels (shrouds) and gaseous helium shrouds to create a simulated space environment. The chamber was originally built to support testing of the Apollo Service and Command Module for lunar missions, but underwent major modifications to be able to test the James Webb Space Telescope in a simulated deep space environment. To date seven tests have been performed in preparation of testing the flight optics for the James Webb Space Telescope (JWST). Each test has had a uniquie thermal profile and set of thermal requirements for cooling down and warming up, controlling contamination, and releasing condensed air. These range from temperatures from 335K to 15K, with tight uniformity and controllability for maintining thermal stability and pressure control. One unique requirement for two test was structurally proof loading hardware by creating thermal gradients at specific temperatures. This paper will discuss the thermal requirements and goals of the tests, the original requirements of the chamber thermal systems for planned operation, and how the new requirements were met by the team using the hardware, system flexiblilty, and engineering creativity. It will also discuss the mistakes and successes to meet the unique goals, especially when meeting the thermal proof load.

    Command and control in today's battlefield environment requires efficient and effective control of massive amounts of constantly changing information from a variety of databases and real-time sensors. Using advanced information technology for presentation and interactive control enables more extensive data fusion and correlation to present an accurate picture of the battlespace to commanders and their staffs. The Interactive DataWall being developed by the Advanced Displays and Intelligent Interfaces (ADII) technology team of the Air Force Research Laboratory's Information Directorate (AFRL/IF) is a strong contender for solving the information management problems facing the 21st century military commander. It provides an ultra high-resolution large screen display with multi-modal, wireless interaction. Commercial off-the-shelf (COTS) technology has been combined with specialized hardware and software developed in-house to provide a unique capability for multimedia data display and control. The technology once isolated to a laboratory environment has been packaged into deployable systems that have been successfully transitioned to support the warfighter in the field.

    Electrical systems can be categorized as critical systems where failure can result in significant financial loss, injury or threats to human life. The operators of the electric power control centers perform an activity in a specialized environment and have to carry it out by mobilizing knowledge and reasoning to which they have adequate training under the terms of the existing rules. To reach this there is a common mental request of personnel involved in these centers due the need to maintain attention, memory and reasoning request. In this sense, this study aims to evaluate the Mental Workload of technical workers of the Control Centers of Electrical Energy. It was undertaken a research on operators control centers of the electricity sector in Northeast Brazil. It was used for systematic observations, followed by interview and application of the instrument National Aeronautics and Space Administration Task Load Index known as NASA-TLX. As a result there will be subsidies for an assessment of mental workload of operators, and a contribution to improving the processes of managing the operation of electric utilities and the quality of workers.

    1994-12-31

    This paper presents work done by Oak Ridge National Laboratory and Remotec, Inc., to develop a new operator-centered control system for Remotec`s Andros telerobot. Andros robots are presently used by numerous electric utilities, the armed forces, and numerous law enforcement agencies to perform tasks which are hazardous for human operators. This project has automated task components and enhanced the video graphics display of the robot`s position in the environment to significantly reduce operator workload. The procedure of automating a telerobot requires the addition of computer power to the robot, along with a variety of sensors and encoders to provide information about the robots performance in and relationship to its environment The resulting vehicle serves as a platform for research on strategies to integrate automated tasks with those performed by a human operator. The addition of these capabilities will greatly enhance the safety and efficiency of performance in hazardous environments.

    With the increased emphasis on aircraft safety, enhanced performance and affordability, and the need to reduce the environmental impact of aircraft, there are many new challenges being faced by the designers of aircraft propulsion systems. Also the propulsion systems required to enable the National Aeronautics and Space Administration (NASA) Vision for Space Exploration in an affordable manner will need to have high reliability, safety and autonomous operation capability. The Controls and Dynamics Branch (CDB) at NASA Glenn Research Center (GRC) in Cleveland, Ohio, is leading and participating in various projects in partnership with other organizations within GRC and across NASA, the U.S. aerospace industry, and academia to develop advanced controls and health management technologies that will help meet these challenges through the concept of Intelligent Propulsion Systems. This paper describes the current activities of the CDB under the NASA Aeronautics Research and Exploration Systems Missions. The programmatic structure of the CDB activities is described along with a brief overview of each of the CDB tasks including research objectives, technical challenges, and recent accomplishments. These tasks include active control of propulsion system components, intelligent propulsion diagnostics and control for reliable fault identification and accommodation, distributed engine control, and investigations into unsteady propulsion systems.

    This paper describes the further development of the substantive theory Optimising Personal Control to Facilitate Emotional Comfort. In previous work, emotional comfort was identified as a therapeutic state that was influenced by several factors, one of which was the hospital environment. This paper focuses on aspects within the hospital environment that patients perceive to influence their feelings of personal control. A relationship between control and health has been discussed in previous literature. There are indications that aspects of the hospital environment can impact on a patient's perception of control. This project explored personal control in relation to the hospital environment from the perspective of patients. Grounded theory method was used. Data were collected from patients' interviews and field observations and analysed using the constant comparative method. Interviews were tape-recorded and transcribed verbatim. A qualitative data computer program was used to manage the data. The results confirmed the findings of the original study where hospitalised patients were found to experience feelings of reduced personal control. The conditions of level of security, level of knowing and level of personal value were described in terms of their contribution to the patient's feelings of personal control. Specific directions for further research into the development and evaluation of therapeutic hospital environments that promote personal control and the associated emotional comfort are provided. This research highlights the importance of considering patients' feelings of personal control during their hospital stay. Several directions for establishment of therapeutic environments within hospitals are provided, but more research in this area is recommended.

    Railway freight center location problem is an important issue in railway freight transport programming. This paper focuses on the railway freight center location problem in uncertain environment. Seeing that the expected value model ignores the negative influence of disadvantageous scenarios, a robust optimization model was proposed. The robust optimization model takes expected cost and deviation value of the scenarios as the objective. A cloud adaptive clonal selection algorithm (C-ACSA) was presented. It combines adaptive clonal selection algorithm with Cloud Model which can improve the convergence rate. Design of the code and progress of the algorithm were proposed. Result of the example demonstrates the model and algorithm are effective. Compared with the expected value cases, the amount of disadvantageous scenarios in robust model reduces from 163 to 21, which prove the result of robust model is more reliable.

    2015-01-01

    CubeSats, Communication Satellites, and Outer Planet Science Satellites all share one thing in common: Mission success depends on maintaining power in the harsh space environment. For a vast majority of satellites, spacecraft power is sourced by a photovoltaic (PV) array system. Built around PV cells, the array systems also include wiring, substrates, connectors, and protection diodes. Each of these components must function properly throughout the mission in order for power production to remain at nominal levels. Failure of even one component can lead to a crippling loss of power. To help ensure PV array systems do not suffer failures on-orbit due to the space environment, NASA's Marshall Space Flight Center (MSFC) has developed a wide ranging test and evaluation capability. Key elements of this capability include: Testing: a. Ultraviolet (UV) Exposure b. Charged Particle Radiation (Electron and Proton) c. Thermal Cycling d. Plasma and Beam Environments Evaluation: a. Electrostatic Discharge (ESD) Screening b. Optical Inspection and easurement c. PV Power Output including Large Area Pulsed Solar Simulator (LAPSS) measurements This paper will describe the elements of the space environment which particularly impact PV array systems. MSFC test capabilities will be described to show how the relevant space environments can be applied to PV array systems in the laboratory. A discussion of MSFC evaluation capabilities will also be provided. The sample evaluation capabilities offer test engineers a means to quantify the effects of the space environment on their PV array system or component. Finally, examples will be shown of the effects of the space environment on actual PV array materials tested at MSFC.

    The widespread application of electric (often called artificial) light in greenhouses, growing rooms, and plant growth chambers would presuppose that the role of phytochrome would be considered in the selection and use of such lighting systems. Unfortunately this is not usually the case. Part of the problem is that many students, and indeed an unfortunate number of senior scientists, seem to regard phytochrome as a laboratory phenomenon without much application in the real world. They simply have not grasped the concept that phytochrome is functioning through all stages of plant development, wherever plants are grown. It is certainly true, as Meijer (1971) stated, that one cannot compare experimental results obtained under very strict laboratory conditions with plant irradiation in glasshouses and in growth rooms. When Karl Norris developed the first practical portable spectroradiometer about 1962, some of the first measurements were to determine the red/far-red ratios under tree canopies. These measurements showed clearly the predominance of far-red in the understory and suggested that far-red was contributing to the elongation exhibited by many species growing in the shade, and possibly was a factor in the induction of light requirements in seeds. Subsequently we used Catalpa leaves as far-red filters to make light-insensitive lettuce seed light requiring. Much more detailed work has since been done on phytochrome effects in the natural environment, and it is encouraging to note that efforts are bring made to apply phytochrome research to horticulture.

    As part of this nation-wide study, in September 2006, historical survey and evaluation of NASA-owned and managed facilities was conducted by NASA's Lyndon B. Johnson Space Center (JSC) in Houston, Texas. The results of this study are presented in a report entitled, Survey and Evaluation of NASA-owned Historic Facilities and Properties in the Context of the U.S. Space Shuttle Program, Lyndon B. Johnson Space Center, Houston, Texas, prepared in November 2007 by NASA JSC s contractor, Archaeological Consultants, Inc. As a result of this survey, the Mission Control Center (Building 30) was determined eligible for listing in the NRHP, with concurrence by the Texas State Historic Preservation Officer (SHPO). The survey concluded that Building 30 is eligible for the NRHP under Criteria A and C in the context of the U.S. Space Shuttle Program (1969-2010). Because it has achieved significance within the past 50 years, Criteria Consideration G applies. It should be noted that the Mission Control Center was designated a National Historic Landmark in 1985 for its role in the Apollo 11 Lunar Landing. At the time of this documentation, Building 30 was still used to support the SSP as an engineering research facility, which is also sometimes used for astronaut training. This documentation package precedes any undertaking as defined by Section 106 of the NHPA, as amended, and implemented in 36 CFR Part 800, as NASA JSC has decided to proactively pursue efforts to mitigate the potential adverse affects of any future modifications to the facility. It includes a historical summary of the Space Shuttle program; the history of JSC in relation to the SSP; a narrative of the history of Building 30 and how it supported the SSP; and a physical description of the structure. In addition, photographs documenting the construction and historical use of Building 30 in support of the SSP, as well as photographs of the facility documenting the existing conditions, special technological features

    2017-01-01

    This presentation will provide an overview of how NASA has been conducting corrosion testing in the Natural Marine Environment at the Kennedy Space Center, Florida, U.S. The following questions will be addressed: What factors should be considered when selecting and constructing a test site? What are the attributes of a good test site? Is more severe always better? What environmental parameters should be monitored? How frequently? What factors should be considered when designing test specimens? Are current test standards sufficient? How do diurnal, annual and other fluctuations in corrosivity influence tests? How are test results interpreted? Can they be quantified?

    To aid the planning of the Apollo Soyuz Test Program (ASTP), certain natural environment statistical relationships are presented, based on Markov theory and empirical counts. The practical results are in terms of conditional probability of favorable and unfavorable launch conditions at Kennedy Space Center (KSC). They are based upon 15 years of recorded weather data which are analyzed under a set of natural environmental launch constraints. Three specific forecasting problems were treated: (1) the length of record of past weather which is useful to a prediction; (2) the effect of persistence in runs of favorable and unfavorable conditions; and (3) the forecasting of future weather in probabilistic terms.

    An approach for establishing quality control in processes which exhibit undesired continual or intermittent excursions in key process parameters is discussed. The method is called deterministic manufacturing, and it is designed to employ automatic monitoring of the key process variables for process certification, but utilizes only sample certification of the process output to verify the validity of the measurement process. The system utilizes a local minicomputer to sample the appropriate process parameters that describe the condition of the machine tool, the cutting process, and the computer numerical control system. Sampled data are pre-processed by the minicomputer and then sent to a host computer that maintains a permanent data base describing the manufacturing conditions for each work piece. Parts are accepted if the various parameters remain within the required limits during the machining cycle. The need for additional actions is flagged if limits are exceeded. With this system it is possible to retrospectively examine the process status just prior to the occurrence of a problem. (LEW)

  10. Follower-Centered Perspective on Feedback: Effects of Feedback Seeking on Identification and Feedback Environment

    2017-01-01

    In the formation mechanism of the feedback environment, the existing research pays attention to external feedback sources and regards individuals as objects passively accepting feedback. Thus, the external source fails to realize the individuals’ need for feedback, and the feedback environment cannot provide them with useful information, leading to a feedback vacuum. The aim of this study is to examine the effect of feedback-seeking by different strategies on the supervisor-feedback environment through supervisor identification. The article consists of an empirical study with a sample of 264 employees in China; here, participants complete a series of questionnaires in three waves. After controlling for the effects of demography, the results indicate that supervisor identification partially mediates the relationship between feedback-seeking (including feedback monitoring and feedback inquiry) and the supervisor-feedback environment. Implications are also discussed.

  11. Adaptation of Control Center Software to Commerical Real-Time Display Applications

    1994-01-01

    NASA-Marshall Space Flight Center (MSFC) is currently developing an enhanced Huntsville Operation Support Center (HOSC) system designed to support multiple spacecraft missions. The Enhanced HOSC is based upon a distributed computing architecture using graphic workstation hardware and industry standard software including POSIX, X Windows, Motif, TCP/IP, and ANSI C. Southwest Research Institute (SwRI) is currently developing a prototype of the Display Services application for this system. Display Services provides the capability to generate and operate real-time data-driven graphic displays. This prototype is a highly functional application designed to allow system end users to easily generate complex data-driven displays. The prototype is easy to use, flexible, highly functional, and portable. Although this prototype is being developed for NASA-MSFC, the general-purpose real-time display capability can be reused in similar mission and process control environments. This includes any environment depending heavily upon real-time data acquisition and display. Reuse of the prototype will be a straight-forward transition because the prototype is portable, is designed to add new display types easily, has a user interface which is separated from the application code, and is very independent of the specifics of NASA-MSFC's system. Reuse of this prototype in other environments is a excellent alternative to creation of a new custom application, or for environments with a large number of users, to purchasing a COTS package.

  12. A cell-centered, agent-based framework that enables flexible environment granularities.

    Mechanistic explanations of cell-level phenomena typically adopt an observer perspective. Explanations developed from a cell's perspective may offer new insights. Agent-based models lend themselves to model from an individual perspective, and existing agent-based models generally utilize a regular lattice-based environment. A framework which utilizes a cell's perspective in an off-lattice environment could improve the overall understanding of biological phenomena. We present an agent-based, discrete event framework, with a demonstrative focus on biomimetic agents. The framework was first developed in 2-dimensions and then extended, with a subset of behaviors, to 3-dimensions. The framework is expected to facilitate studies of more complex biological phenomena through exploitation of a dynamic Delaunay and Voronoi off-lattice environment. We used the framework to model biological cells and to specifically demonstrate basic biological cell behaviors in two- and three-dimensional space. Potential use cases are highlighted, suggesting the utility of the framework in various scenarios. The framework presented in this manuscript expands on existing cell- and agent-centered methods by offering a new perspective in an off-lattice environment. As the demand for biomimetic models grows, the demand for new methods, such as the presented Delaunay and Voronoi framework, is expected to increase.

  13. Mission Control Center (MCC) System Specification for the Shuttle Orbital Flight Test (OFT) Timeframe

    1976-01-01

    System specifications to be used by the mission control center (MCC) for the shuttle orbital flight test (OFT) time frame were described. The three support systems discussed are the communication interface system (CIS), the data computation complex (DCC), and the display and control system (DCS), all of which may interfere with, and share processing facilities with other applications processing supporting current MCC programs. The MCC shall provide centralized control of the space shuttle OFT from launch through orbital flight, entry, and landing until the Orbiter comes to a stop on the runway. This control shall include the functions of vehicle management in the area of hardware configuration (verification), flight planning, communication and instrumentation configuration management, trajectory, software and consumables, payloads management, flight safety, and verification of test conditions/environment.

    Research consistently finds that low self-control is significantly correlated with delinquency. Only recently, however, have researchers started to examine associations between parental low self-control, family environments, and child antisocial behavior. Adding to this emerging area of research, the current study examines associations between parental low self-control, aspects of the family environment, and officially recoded juvenile delinquency among a sample (N = 101) of juveniles processed through a juvenile justice assessment facility located in the Southeastern United States. Furthermore, it considers whether aspects of family environments, particularly family cohesion, family conflict, and parental efficacy, mediate the influence of parental low self-control on delinquency. The results of a series of analyses indicate that parental low self-control is correlated with various aspects of family environments and juvenile delinquency, and that the association between parental low self-control and juvenile delinquency is mediated by family environments. Supplementary analyses also suggest that the association between parental low self-control and the family environment may be reciprocal.

    This article synthesizes and describes the lessons learned from the Network Operations Control Center (NOCC) upgrade project, from the requirements phase through development and test and transfer. At the outset, the NOCC upgrade was being performed simultaneously with two other interfacing and dependent upgrades at the Signal Processing Center (SPC) and Ground Communications Facility (GCF), thereby adding a significant measure of complexity to the management and overall coordination of the development and transfer-to-operations (DTO) effort. Like other success stories, this project carried with it the traditional elements of top management support and exceptional dedication of cognizant personnel. Additionally, there were several NOCC-specific reasons for success, such as end-to-end system engineering, adoption of open-system architecture, thorough requirements management, and use of appropriate off-the-shelf technologies. On the other hand, there were several difficulties, such as ill-defined external interfaces, transition issues caused by new communications protocols, ambivalent use of two sets of policies and standards, and mistailoring of the new JPL management standard (due to the lack of practical guidelines). This article highlights the key lessons learned, as a means of constructive suggestions for the benefit of future projects.

    1988-01-01

    This report summarizes the current status of CTA's investigation of methods and tools for automating the software development process in NASA Goddard Space Flight Center, Code 500. The emphasis in this effort has been on methods and tools in support of software reuse. The most recent phase of the effort has been a domain analysis of Payload Operations Control Center (POCC) software. This report summarizes the results of the domain analysis, and proposes an approach to semi-automatic development of POCC Application Processor (AP) software based on these results. The domain analysis enabled us to abstract, from specific systems, the typical components of a POCC AP. We were also able to identify patterns in the way one AP might be different from another. These two perspectives--aspects that tend to change from AP to AP, and aspects that tend to remain the same--suggest an overall approach to the reuse of POCC AP software. We found that different parts of an AP require different development technologies. We propose a hybrid approach that combines constructive and generative technologies. Constructive methods emphasize the assembly of pre-defined reusable components. Generative methods provide for automated generation of software from specifications in a very-high-level language (VHLL).

    1995-12-01

    The medical office building (MOB) has been the mainstay of the health care industry for many years. Recently, with the development of new diagnostic and treatment equipment, new facilities are being designed and built. Some are large, serving many physicians and their patients. Others are quite small, having as few as two doctors. Some are new structures while others are converted facilities. Some are located close to the hospitals they are associated with; others are located as satellites at the fringe of a hospital`s local service area. Mechanical systems vary widely and are dictated by building size, number of offices, number of treatment rooms, patient capacity, local codes, and the requirements of the staff. In a large MOB, the systems would like include HVAC, extensive plumbing, fire protection, and medical gas systems. A small, two- or three-doctor office may only have HVAC, basic plumbing, and perhaps some detectors. This article examines the environmental control aspects of medical clinics, including facilities with one or two offices and multistory medical office buildings.

    The sporangiophore of the fungus Phycomyces bends away from nearby objects without ever touching them. It has been thought that these objects act as aerodynamic obstacles that damp random winds, thereby generating asymmetric distributions of a growth-promoting gas emitted by the growth zone. In the interest of testing this hypothesis, we studied avoidance in an environmental chamber in which convection was suppressed by a shallow thermal gradient. We also controlled pressure, temperature, and relative humidity of the air, electrostatic charge, and ambient light. A protocol was established that yielded avoidance rates constant from sporangiophore to sporangiophore to within +/- 10%. We found that avoidance occurred at normal rates in the complete absence of random winds. The rates were smaller at 100% than at lower values of relative humidity, but not by much. Remarkably, at a distance as great as 0.5 mm, avoidance from a 30-micron diam glass fiber (aligned parallel to the sporangiophore) was about the same as that from a planar glass sheet. However, the rate for the fiber fell more rapidly with distance. The rate for the sheet remained nearly constant out to approximately 4 mm. We conclude that avoidance depends either on adsorption by the barrier of a growth-inhibiting substance or emission by the barrier of a growth-promoting substance; it cannot occur by passive reflection. Models that can explain these effects are analyzed in the Appendix. PMID:3567313

  19. Factors controlling arsenic adsorption in the environment

    Recent epidemiological studies on arsenic report that the cancer risk associated with arsenic at the current maximum contaminant level (MCL) of 50 {mu}g/L is much greater than previously believed. In response to these findings, the U.S. Environmental Protection Agency intends to decrease the MCL to between 2 and 20 {mu}g/L. The efficiency of arsenic removal in water treatment and the ambient levels of arsenic in source waters are both strongly influenced by the extent of arsenic adsorption to oxide surfaces. An investigation of ft factors controlling arsenic adsorption is crucial to evaluate properly the effectiveness of arsenic removal technologies such as enhanced coagulation. This study examined the effects of the following parameters on arsenic adsorption to preformed hydrous ferric oxide: arsenic oxidation state, initial arsenic concentration, pH and the presence of sulfate. The studies were carried out over initial arsenic concentrations between 2.5 and 100 {mu}g/L (0.33 and 1.34 {mu}M).

    Orbital flight tests of the Space Shuttle Program involved three types of activities, including classic flight testing of the vehicle hardware and software, operational procedures evaluation and development, and performance of payload mission operations. This combination of activities required a capability of the Mission Control Center (MCC) to provide thorough support to the Orbiter and its crew across a broad spectrum of activities. Attention is given to MCC organization, the general functions performed by the MCC teams, a flight support description, the motivation for a change in MCC operations, support elements, orbit phase functions, and dynamic flight phase functions. It is pointed out that the MCC facilities for the operational mode of support will not be fully implemented until 1984.

    General concern about increasing reports of emergencies caused by or attributed to the exposure of human beings to various toxic agents has created demand for assessing the informational performance of a Brazilian network of 34 poison control centers (PCCs), located in different regions of the country and pertaining to the National Poison Information System (SINITOX). The primary purpose of these PCCs is to inform the public, prevent cases of poisoning, and provide medical care. This paper analyzes the available resources for identifying cases of poisoning, preventing new occurrences, and monitoring the consequences of toxic agents. This paper also analyzes data recorded front 1990 to 1992. The objective is to identify the main constraints to using health-data and management information as decision-making tools at the local level.

    A computer program has been developed for the dietetic service of the Clinical Research Center at the University of Florida. Presently, it is used in menu planning and nutrient analysis for selective, controlled-nutrient diets and for constant diets. The program is able to compute food weights for a patient-selected daily menu which would satisfy up to twenty-three nutrient constraints and which may be optimized with respect to one or more of these. The principal benefit of the program is a saving in the dietetian's time in calculating the nutrient content of the diet and in planning diets with several constrained nutrients. It is also being used as a teaching resource for dietetic interns and dietetic trainees.

Fracture rate was significantly greater in residents with: epilepsy, older age, male gender, white race, independent ambulation, osteoporosis, and residence in intermediate care (versus skilled nursing) units; it was not affected by severity of mental retardation. Hand and foot bones were fractured in 58% of cases. Femur fracture occurred in 13 cases (7%). Fracture was caused by a fall in 41 cases (23%); its cause was indeterminable in 105 cases (58%). Fractures, occurring without significant injury, may be an important cause of preventable disability in this population. Control measures are suggested. Images Figure 1. Figure 2. PMID:10344173

    Child-care centers are an integral part of life for many families with young children. American Indian children are at elevated health risk because of higher levels of obesity and associated health behaviors. Our aim was to assess the child-care environment and children's physical activity (PA) and dietary intake in young children attending tribally affiliated child care. We conducted a cross-sectional study. Participants were from 11 tribally affiliated child-care centers across Oklahoma and included 82 children aged 3 to 5 years old. Classroom observations were conducted using the Environmental and Policy Assessment Observation to measure PA and nutrition environments. Children wore an ActiGraph GT3X accelerometer and lunchtime plate waste was observed. Descriptive statistics, including mean±standard deviation and frequencies, were calculated for the children's behaviors and environment. The total environment score was 23.9±5.2 (maximum=43). The nutrition score was 12.5±3.1 (maximum=21). The PA score was 11.7±2.2 (maximum=22). The participants were 3.8±0.1 years old, 55% were male, 67% were American Indian, and 38% were overweight or obese. Accelerometers were worn for 5.9±1.7 hours, excluding naptime. Children accumulated 4.3±2.2 min/h of moderate to vigorous PA, 4,294±1,883 steps/day, and 12.1±3.7 steps/min. At lunch, children were served 510±241 kcal, and consumed 387±239 kcal. Lunches consisted of 47% carbohydrate, 20% protein, and 33% fat. Total number of F/V served was 2.9±1.9 and consumed was 2.3±1.8, while whole grains served and consumed were 0.3±0.4 and 0.2±0.4, respectively, and lean proteins served and consumed were 0.3±0.4 and 0.2±0.4, respectively. This study describes obesogenic aspects of the child-care environment and identifies areas for improvement. Children did not accumulate adequate PA or consume calories or fat excessively. Children consumed multiple F/V; however, more whole grains and lean proteins could be provided

  11. Body orientation and center of mass control in microgravity

    Massion, J.; Popov, K.; Fabre, J.-C.; Rage, P.; Gurfmkel, V.

    The control of the body orientation and the center of mass position with respect to the feet was investigated under normo- and microgravity (space flight Altair), during erect posture and at the end of a forward or backward upper trunk movement. It was observed that during erect posture, the trunk orientation with respect to the vertical was inclined some 6 ° forward in both subjects under microgravity, whereas it was vertical or slightly backward oriented under normogravity. Under microgravity, on the contrary, the initial position CM changed either backwards or forwards. This result suggests that the inclined trunk posture might be due to misevaluating the vertically under microgravity and that different control mechanisms are involved in orienting the trunk and placing the CM. It was also noted that the final position of the CM at the end of the movement did not differ markedly between microgravity and normogravity. This result suggests that the kinematic synergies which stabilize the CM during uppertrunk movements may result from an automatic central control which is independent from the gravity constraints.

    A Centaur rocket control room in the Development Engineering Building (DEB) at the National Aeronautics and Space Administration (NASA) Lewis Research Center in Cleveland, Ohio. The DEB, completed in the mid-1960s, provided office space for several hundred development engineers outside the center’s main gate. The location of the DEB emphasized the development staff’s separation from the research side of the laboratory. This control room at Lewis was directly linked to Cape Kennedy. The Lewis staff in Cleveland could monitor and back up the Lewis launch team in the actual control room at the Cape. This photograph was taken during the preparations for the Titan-Centaur-Helios launch on December 10, 1974. The panels to the left listed the countdown events for the Centaur rocket. The launch countdown clock can be seen above these panels. The two panels on the right listed events predicted to occur during the flight and the availability of the tracking stations. The clock above the panels indicated the time remaining before the launch window expired. The Launch Vehicles Division was created in 1969 to manage the launches of all Centaur and Agena rockets. The Launch Vehicles Division worked with the engineers to design the payload in a manner that ensured that its size and weight were within Centaur’s parameters. They also developed the proper trajectory analysis for the launch. These trajectories often had to be adjusted if the launch did not occur on the planned date.

    1988-01-01

    Plant growth in a controlled ecological life support system may entail the build-up over extended time periods of phytotoxic concentrations of volatile organic compounds produced by the plants themselves. Ethylene is a prominent gaseous emission of plants, and is the focus of this report. The objective was to determine the rate of ethylene release by spring wheat, white potato, and lettuce during early, middle, and late growth stages, and during both the light and dark segments of the diurnal cycle. Plants grown hydroponically using the nutrient film technique were covered with plexiglass containers for 4 to 6 h. At intervals after enclosure, gas samples were withdrawn with a syringe and analyzed for ethylene with a gas chromatograph. Lettuce produced 10 to 100 times more ethylene than wheat or potato, with production rates ranging from 141 to 158 ng g-dry/wt/h. Wheat produced from 1.7 to 14.3 ng g-dry/wt/h, with senescent wheat producing the least amount and flowering wheat the most. Potatoes produced the least amount of ethylene, with values never exceeding 5 ng g-dry/wt/h. Lettuce and potatoes each produced ethylene at similar rates whether in dark period or light period. Ethylene sequestering of 33 to 43 percent by the plexiglass enclosures indicated that these production estimates may be low by one-third to one-half. These results suggest that concern for ethylene build-up in a contained atmosphere should be greatest when growing lettuce, and less when growing wheat or potato.

The requirements for a Manned Space-Laboratories Control Center (MSCC) as defined at the beginning of the planning and construction process in 1987 and the resulting modifications during the various programmatic scenario changes on NASA and ESA side between 1987 and now are presented. The validity of the original requirements with respect to the current scenario, which asks for a logical evolution from the execution of the D-2 mission in January 1993 via the European Columbus Precursor flights (in particular the E-1 mission) towards Columbus Attached Laboratory (APM)-operations by the end of this century are discussed. The resulting tasks of the MSCC for the various missions, the current configuration, and the ensuing operations concept leading from a more centralized concept for D-2 towards a decentralized payload operations concept for the APM and the implications with respect to European and International interfaces are presented. The planned Columbus MSCC facility architecture and its expected modifications introduced by the ESA Ministerial Conference in Munich (Nov. 1991) and follow-on discussions are briefly addressed. The last chapter outlines the planned services to be provided by the MSCC to the decentralized User (experimenter) community. Issues like decentralized mission planning on executional level, command validation, data flow coordination, archiving services, and telescience capabilities are highlighted from a MSCC point of view.

    To optimize family-centered care and the staff working environment, the physical care environment should be designed to meet the needs of the infants, their families, and staff. It is important to evaluate the effects of a purpose-built neonatal ward on staff perceptions of job strain, the psychosocial climate, and the appropriateness of the physical environment. This study collected information from staff at a neonatal intensive care unit (NICU), before and after the ward was relocated to a new NICU. Effects were measured using the following variables: job strain, person-centered climate and appropriateness-of-the-physical-environment questionnaires. Data were analyzed using repeated-measures generalized estimating equations and factor analysis. After staff began to work in the new NICU, their job strain significantly increased. At the 2-year follow-up, staff stress levels had returned to preintervention levels. Participating staff perceived the purpose-built neonatal ward as being a significantly more appropriate physical environment for family-centered care of the infants and their families. The staff also perceived the psychosocial climate of the new NICU as significantly more person-centered in terms of having a more homey, comfortable, and everyday ambience and thus experienced as being more supportive. An NICU built according to recommended standards optimized the physical care environment for family-centered care and increased the staff working climate.

  16. Electric Power Research Institute: environmental Control Technology Center.

    SciTech Connect

    1997-09-04

    Operations and maintenance continued this month at the Electric Power Research Institute`s (EPRI`s) Environmental Control Technology Center (ECTC). Testing for the month involved continued investigations into the Clear Liquor Scrubbing Process for the production of Anhydrous Calcium Sulfate (Anhydrite). The 1.0 MW Cold-Side Selective Catalytic Reduction (SCR) unit and the Carbon Injection System (the Pulse-jet Fabric Filter) remained idle this month in a cold-standby mode and were inspected regularly. From May 3-18, the NYSEG Kintigh Station and the ECTC were off-line for a two-week scheduled Station outage. During the ECTC outage, the major systems of the Center were inspected, and several preventive maintenance activities were completed. A listing of the major O&M outage activities completed during this period is presented in the Pilot/Mini-Pilot section of this report. In May 1997, an extension to the Anhydrite Production test block was started following the NYSEG outage. The extension to the Anhydrite Production test block is being funded by the Electric Power Research Institute (EPRI) after promising results from the original test program. Both EPRI and the Department of Energy (DOE) funded the original test program as part of the DOE`s Advanced Power Systems Program, whose mission is to accelerate the commercialization of affordable, high- efficiency, low-emission, coal-fueled electric generating technologies. While the pilot portion of the Anhydrite project was conducted on the 4.0 MW wet FGD pilot unit at EPRI`s Environmental Control Technology Center (ECTC) in Barker, New York, the extension mainly used the 0.4 MW Mini-Pilot wet FGD unit to reduce operating costs. The project is designed to develop an advanced FGD process that produces a useable byproduct, anhydrite (anhydrous calcium sulfate). The original CLS/Anhydrite process included three steps: chloride removal, clear liquor scrubbing, and anhydrite production. The final step in the process involved

    2013-05-01

    As more enterprises are enticed to move data to a cloud environment to enhance data sharing and reduce operating costs by exploiting shared resources, concerns have risen over the ability to secure information within the cloud. This paper examines how a traditional Identity and Access Control (IDAM) architecture can be adapted to address security concerns of a cloud environment. We propose changing the paradigm of IDAM form a pure trust model to a risk based model will enable information to be protected securely in a cloud environment without impacting efficiencies of cloud environments.

  5. Early prediction of student goals and affect in narrative-centered learning environments

    NASA Astrophysics Data System (ADS)

    Lee, Sunyoung

    Recent years have seen a growing recognition of the role of goal and affect recognition in intelligent tutoring systems. Goal recognition is the task of inferring users' goals from a sequence of observations of their actions. Because of the uncertainty inherent in every facet of human computer interaction, goal recognition is challenging, particularly in contexts in which users can perform many actions in any order, as is the case with intelligent tutoring systems. Affect recognition is the task of identifying the emotional state of a user from a variety of physical cues, which are produced in response to affective changes in the individual. Accurately recognizing student goals and affect states could contribute to more effective and motivating interactions in intelligent tutoring systems. By exploiting knowledge of student goals and affect states, intelligent tutoring systems can dynamically modify their behavior to better support individual students. To create effective interactions in intelligent tutoring systems, goal and affect recognition models should satisfy two key requirements. First, because incorrectly predicted goals and affect states could significantly diminish the effectiveness of interactive systems, goal and affect recognition models should provide accurate predictions of user goals and affect states. When observations of users' activities become available, recognizers should make accurate early" predictions. Second, goal and affect recognition models should be highly efficient so they can operate in real time. To address key issues, we present an inductive approach to recognizing student goals and affect states in intelligent tutoring systems by learning goals and affect recognition models. Our work focuses on goal and affect recognition in an important new class of intelligent tutoring systems, narrative-centered learning environments. We report the results of empirical studies of induced recognition models from observations of students

    With the advent of broadcast television as a constant source of information throughout the NASA manned space flight Mission Control Center (MCC) at the Johnson Space Center (JSC), the current Video Transport System (VTS) characteristics provides the ability to visually enhance real-time applications as a broadcast channel that decision making flight controllers come to rely on, but can be difficult to maintain and costly. The Operations Technology Facility (OTF) of the Mission Operations Facility Division (MOFD) has been tasked to provide insight to new innovative technological solutions for the MCC environment focusing on alternative architectures for a VTS. New technology will be provided to enable sharing of all imagery from one specific computer display, better known as Display Sharing (DS), to other computer displays and display systems such as; large projector systems, flight control rooms, and back supporting rooms throughout the facilities and other offsite centers using IP networks. It has been stated that Internet Protocol (IP) applications are easily readied to substitute for the current visual architecture, but quality and speed may need to be forfeited for reducing cost and maintainability. Although the IP infrastructure can support many technologies, the simple task of sharing ones computer display can be rather clumsy and difficult to configure and manage to the many operators and products. The DS process shall invest in collectively automating the sharing of images while focusing on such characteristics as; managing bandwidth, encrypting security measures, synchronizing disconnections from loss of signal / loss of acquisitions, performance latency, and provide functions like, scalability, multi-sharing, ease of initial integration / sustained configuration, integration with video adjustments packages, collaborative tools, host / recipient controllability, and the utmost paramount priority, an enterprise solution that provides ownership to the whole

    2003-09-01

    In this paper a survey of plant environment control in artificial greenhouse was put forward for discussing the future development. Firstly, plant environment control started with the closed loop control of air temperature in greenhouse. With the emergence of higher property computer, the adaptive control algorithm and system identification were integrated into the control system. As adaptation control is more depending on observation of variables by sensors and yet many variables are unobservable or difficult to observe, especially for observation of crop growth status, so model-based control algorithm were developed. In order to evade modeling difficulty, one method is predigesting the models and the other method is utilizing fuzzy logic and neural network technology that realize the models by the black box and gray box theory. Studies on control method of plant environment in greenhouse by means of expert system (ES) and artificial intelligence (AI) have been initiated and developed. Nowadays, the research of greenhouse environment control focus on energy saving, optimal economic profit, enviornment protection and continualy develop.

    1994-12-01

    The SSC is developing a design environment for control system development within the context of EPICS. The environment is aimed at developers of applications using the EPICS Input/Output Controller (IOC). The unique aspect of this effort is our emphasis on providing a simple and intuitive development environment compared with tools currently available. Our most important goal in this effort has been to hide the complexity of EPICS IOC development from the developers. This paper describes two tools which are under development; The Function Block Editor (FBE) and the State Machine Editor (SME). The FBE provides a visual editing environment for graphically describing control processes as a set of related functional blocks. The configuration of functional blocks is then translated into IOC records and executed. SME allows the user to visually construct a sequence using a notation we are modeling after Grafcet [1]. State machines are translated into EPICS State Notation Language programs and executed. Future extensions will be described.

    Chamber A is the largest thermal vacuum chamber at the Johnson Space Center and is one of the largest space environment chambers in the world. The chamber is 19.8 m (65 ft) in diameter and 36.6 m (120 ft) tall and is equipped with cryogenic liquid nitrogen panels (shrouds) and gaseous helium shrouds to create a simulated space environment. It was originally designed and built in the mid 1960 s to test the Apollo Command and Service Module and several manned tests were conducted on that spacecraft, contributing to the success of the program. The chamber has been used since that time to test spacecraft active thermal control systems, Shuttle DTO, DOD, and ESA hardware in simulated Low Earth Orbit (LEO) conditions. NASA is now moving from LEO towards exploration of locations with environments approaching those of deep space. Therefore, Chamber A has undergone major modifications to enable it to simulate these deeper space environments. Environmental requirements were driven, and modifications were funded by the James Webb Space Telescope program, and this telescope which will orbit Solar/Earth L2, will be the first test article to benefit from the chamber s new capabilities. To accommodate JWST, the Chamber A high vacuum system has been modernized, additional LN2 shrouds have been installed, the liquid nitrogen system has been modified to remove dependency on electrical power and increase its reliability, a new helium shroud/refrigeration system has been installed to create a colder more stable and uniform heat sink, and the controls have been updated to increase the level of automation and improve operator interfaces. Testing of these major modifications was conducted in August of 2012 and this initial test was very successful, with all major systems exceeding their performance requirements. This paper will outline the changes in overall environmental requirements, discuss the technical design data that was used in the decisions leading to the extensive modifications

    1989-01-01

    The KALI distributed robot programming and control environment is described within the context of its use in the Jet Propulsion Laboratory (JPL) telerobot project. The purpose of KALI is to provide a flexible robot programming and control environment for coordinated multi-arm robots. Flexibility, both in hardware configuration and software, is desired so that it can be easily modified to test various concepts in robot programming and control, e.g., multi-arm control, force control, sensor integration, teleoperation, and shared control. In the programming environment, user programs written in the C programming language describe trajectories for multiple coordinated manipulators with the aid of KALI function libraries. A system of multiple coordinated manipulators is considered within the programming environment as one motion system. The user plans the trajectory of one controlled Cartesian frame associated with a motion system and describes the positions of the manipulators with respect to that frame. Smooth Cartesian trajectories are achieved through a blending of successive path segments. The manipulator and load dynamics are considered during trajectory generation so that given interface force limits are not exceeded.

Each volunteering, consenting senior was placed into one of two groups: walking tours outside, then discussions (n=37); and focus group discussions indoors about photographs of BE conditions potentially influencing mobility (n=43). The authors sought to identify BE factors-both real and perceived by participating seniors-related to their ability to walk around senior wellness centers in a healthy and safe manner. The authors focused specifically on available literature and pilot study data for their concept of "safe senior zones" around senior wellness centers serving urban communities in this article. They also characterized their study population regarding sociodemographic variables and doctor-diagnosed chronic diseases, and types of walking aids reported used to help prevent falls. Their results can inform future applied practice and research on traffic-related exposures and BE factors concerning seniors, and support policy and planning to benefit community environmental public health.

    There is still no evidence in literature for damage control orthopaedics (DCO), early total care (ETC) or using external fixation solely in fractures of the long bones in multi-system-trauma. The aim of this study was to determine parameters influencing the choice of treatment in clinical routine (DCO, ETC, or EF) in femoral or tibial shaft fractures in combination with multi-system-trauma, severe soft tissue damage or both. Data of 236 patients with 280 fractures of long bones of the lower extremities treated at a level I trauma center were analysed. Clinical parameters on arrival (age, sex [m/f], ISS, fracture site [femur/tibia], soft tissue damage [closed or open fractures according to the Gustilo-Anderson classification], pulmonary injury [yes/no]) were collected and analysed whether they influence the choice of upcoming treatment (DCO/ETC/EF). Our findings showed that high ISS and severe soft tissue damage (grade III) significantly correlated with DCO. High ISS, old age, female sex and fracture site (tibia) correlated with EF. This group of sole use of external fixation had highest rate of complications, 69% were associated with at least one complication. Severely injured patients are treated significantly more often with DCO or EF. The presence of higher ISS (≥16) and of type III open fractures increased the use of DCO. However, ISS, fracture-site, patient's age, type III open fractures or sex (female) increased the use of EF compared to ETC.

    We tested two pigeons in a continuously streaming digital environment. Using animation software that constantly presented a dynamic, three-dimensional (3D) environment, the animals were tested with a conditional object identification task. The correct object at a given time depended on the virtual context currently streaming in front of the pigeon. Pigeons were required to accurately peck correct target objects in the environment for food reward, while suppressing any pecks to intermixed distractor objects which delayed the next object’s presentation. Experiment 1 established that the pigeons’ discrimination of two objects could be controlled by the surface material of the digital terrain. Experiment 2 established that the pigeons’ discrimination of four objects could be conjunctively controlled by both the surface material and topography of the streaming environment. These experiments indicate that pigeons can simultaneously process and use at least two context cues from a streaming environment to control their identification behavior of passing objects. These results add to the promise of testing interactive digital environments with animals to advance our understanding of cognition and behavior. PMID:26781058

    Space science models are essential component of integrated data environment. Space science models are indispensable tools to facilitate effective use of wide variety of distributed scientific sources and to place multi-point local measurements into global context. The Community Coordinated Modeling Center (CCMC) hosts a set of state-of-the- art space science models ranging from the solar atmosphere to the Earth's upper atmosphere. The majority of models residing at CCMC are comprehensive computationally intensive physics-based models. To allow the models to be driven by data relevant to particular events, the CCMC developed an online data file generation tool that automatically downloads data from data providers and transforms them to required format. CCMC provides a tailored web-based visualization interface for the model output, as well as the capability to download simulations output in portable standard format with comprehensive metadata and user-friendly model output analysis library of routines that can be called from any C supporting language. CCMC is developing data interpolation tools that enable to present model output in the same format as observations. CCMC invite community comments and suggestions to better address science needs for the integrated data environment.

    Leaders in academic health centers (AHCs) must create a vision for their academic unit embedded in a complex environment. A formal strategic planning process can be valuable to help shape a clear vision taking advantage of potential collaborations and to develop specific achievable long- and short-term goals. The authors describe the steps in a formal strategic planning process and illustrate it with the example of the Department of Medicine at the University of Toronto Faculty of Medicine beginning in 2004. The process included the active participation of over 300 faculty members, trainees, and stakeholders of the department and resulted in broad-based support and leadership for the resulting plan. The authors describe the steps, which include getting started, committing to planning principles, establishing the work plan, understanding the environment, pulling it all together, shaping the vision, testing strategic directions, building effective implementation, and promoting the plan. Articulation of vision, mission, and values informed the plan's development, as well as 10 key principles integral to the plan. Challenges and lessons learned are also described. The final strategic plan is an active core activity of the department, guiding decisions and resource allocation and facilitating measurement of success or shortcomings. The process the authors describe is applicable to multiple academic units, including divisions/sections, departments, or thematic programs in AHCs.

    Development of axonal connections between cat primary visual area 17 and visual motion processing center was studied to investigate cortico-cortical connection plasticity in ontogenesis as affected by an experimental modification of visual environment (flickering light stimulation). By using a retrograde axonal labeling by horseradish peroxidase, a distribution of initial neurons in area 17 that send afferent projections to PMLS (posterior medial part of lateral suprasylvian sulcus) was analyzed. Sixteen 5-week-old and 12-14-week-old kittens, than were reared in normal visual environment or were subjected to a flickering light of 15 Hz frequency, were examined. It was shown that session stimulation by flickering light led to an impairment of normal development of regular organization of the connections between these visual areas including the decrease of labeled surface area and labeled initial neuron density in area 17. The data obtained elucidate the structural bases of cortical mechanisms that underlie motion processing disturbances in kittens stimulated by a flickering light.

    BACKGROUND Numerically, nurses represent the largest healthcare profession, thus setting norms for the quality and safety of direct patient care. Evidence of a global shortage of nurses in all clinical practice settings across different healthcare systems and countries has been documented. The aims of the present study were: (1) to assess work environments in a sample of German transplant nurses, and (2) to compare their statements with a US-based sample. MATERIAL AND METHODS In a cross-sectional study, 181 transplant nurses from 16 German transplant centers provided information on their work environments. The translated version of the Job Design (JD) and Job Satisfaction (JS) survey showed satisfactory internal consistency for the JD (0.78) and JS (0.93) subscales. German nurses' work environments were compared with 331 transplant nurses from the US. RESULTS The majority of transplant nurses were female (81.8%), 55.4% were age 21-40 years, and 78.1% were employed full-time. German (versus US) transplant nurses reported their job design to be best for 'skill varieties' (p≤0.0002), and worst for 'autonomy' (p≤0.01). Job satisfaction was best with 'opportunities for autonomy and growth' (p≤0.0001), and 'pay and benefits' (p≤0.0001) was lowest. A higher professional degree (OR 1.57; p≤0.03; 95% CI 1.19-2.86), and longer time in transplant (OR 1.24; p≤0.001; 95% CI 1.11-1.38) showed a positive impact on German transplant nurses' perceptions of 'job satisfaction'. Nurses with time-dependent working contracts perceived more stress negatively affecting job satisfaction (OR 1.13; p≤0.009; 95% CI 1.02-12.82). CONCLUSIONS German specialty nurses working in the field of solid organ transplantation rate their work environments with respect to job design and job satisfaction as satisfactory. Institutions' investment into satisfactory nurse work environments and specializing nurses might increase the quality of care, thus improving patient outcomes.

    2002-01-01

    A computer program was developed to study multiple crop production and control in controlled environment plant production systems. The program simulates crop growth and development under nominal and off-nominal environments. Time-series crop models for wheat (Triticum aestivum), soybean (Glycine max), and white potato (Solanum tuberosum) are integrated with a model-based predictive controller. The controller evaluates and compensates for effects of environmental disturbances on crop production scheduling. The crop models consist of a set of nonlinear polynomial equations, six for each crop, developed using multivariate polynomial regression (MPR). Simulated data from DSSAT crop models, previously modified for crop production in controlled environments with hydroponics under elevated atmospheric carbon dioxide concentration, were used for the MPR fitting. The model-based predictive controller adjusts light intensity, air temperature, and carbon dioxide concentration set points in response to environmental perturbations. Control signals are determined from minimization of a cost function, which is based on the weighted control effort and squared-error between the system response and desired reference signal.

The Huntsville Operations Support Center (HOSC) Spacelab Payload Operations Control Center (SL POCC) at the Marshall Space Flight Center (MSFC) was the air/ground communication channel used between the astronauts and ground control teams during the Spacelab missions. Teams of controllers and researchers directed on-orbit science operations, sent commands to the spacecraft, received data from experiments aboard the Space Shuttle, adjusted mission schedules to take advantage of unexpected science opportunities or unexpected results, and worked with crew members to resolve problems with their experiments. Due to loss of data used for pointing and operating the ultraviolet telescopes, MSFC ground teams were forced to aim the telescopes with fine tuning by the flight crew.

    1993-01-01

    In its search for higher level computer interfaces and more realistic electronic simulations for measurement and spatial analysis in human factors design, NASA at MSFC is evaluating the functionality of virtual reality (VR) technology. Virtual reality simulation generates a three dimensional environment in which the participant appears to be enveloped. It is a type of interactive simulation in which humans are not only involved, but included. Virtual reality technology is still in the experimental phase, but it appears to be the next logical step after computer aided three-dimensional animation in transferring the viewer from a passive to an active role in experiencing and evaluating an environment. There is great potential for using this new technology when designing environments for more successful interaction, both with the environment and with another participant in a remote location. At the University of North Carolina, a VR simulation of a the planned Sitterson Hall, revealed a flaw in the building's design that had not been observed during examination of the more traditional building plan simulation methods on paper and on computer aided design (CAD) work station. The virtual environment enables multiple participants in remote locations to come together and interact with one another and with the environment. Each participant is capable of seeing herself and the other participants and of interacting with them within the simulated environment.

  1. Improving the life science (biology) laboratory education experience: From an instructor-centered to a learner-centered educational environment

    NASA Astrophysics Data System (ADS)

    Stevens, Marcella Liffick

    The component parts of the educational experience in a freshman biology laboratory course could be improved if the knowledge, skills, and personality of the students could be integrated with the instructor's. Lack of integration of instruction with learning often results in students unwilling or unable to learn content and to transfer it to future courses. This research examined the component parts of instruction and learning for a freshman biology laboratory class and provided an alternative approach to the traditional experience in this lab. Outcome assessment revealed that students experiencing a learner-centered lab responded differently to instruction than students in the traditional lab did and expressed more of a learning orientation and awareness. Not all methods used were successful but course evaluations demonstrated an increased awareness of the learning process among students in the learner-centered lab. The alternative group indicated differences specifically directed toward learning, more often than the traditional group did.

  2. Multiagent Flight Control in Dynamic Environments with Cooperative Coevolutionary Algorithms

    2014-01-01

    Dynamic environments in which objectives and environmental features change with respect to time pose a difficult problem with regards to planning optimal paths through these environments. Path planning methods are typically computationally expensive, and are often difficult to implement in real time if system objectives are changed. This computational problem is compounded when multiple agents are present in the system, as the state and action space grows exponentially with the number of agents in the system. In this work, we use cooperative coevolutionary algorithms in order to develop policies which control agent motion in a dynamic multiagent unmanned aerial system environment such that goals and perceptions change, while ensuring safety constraints are not violated. Rather than replanning new paths when the environment changes, we develop a policy which can map the new environmental features to a trajectory for the agent while ensuring safe and reliable operation, while providing 92% of the theoretically optimal performance.

    The Oak Ridge National Laboratory is currently assisting in the development of advanced control systems for the next generation of nuclear power plants. This paper presents a prototype interactive and intelligent simulation environment being developed to support this effort. The environment combines tools from the field of Artificial Intelligence; in particular object-oriented programming, a LISP programming environment, and a direct manipulation user interface; with traditional numerical methods for simulating combined continuous/discrete processes. The resulting environment is highly interactive and easy to use. Models may be created and modified quickly through a window oriented direct manipulation interface. Models may be modified at any time, even as the simulation is running, and the results observed immediately via real-time graphics. 8 refs., 3 figs.

    In this paper we present a hybrid control scheme, combining the advantages of task-space and joint-space control. The controller is based on a human-like adaptive design, which minimises both control effort and tracking error. Our novel hybrid adaptive controller has been tested in extensive simulations, in a scenario where a Baxter robot manipulator is affected by external disturbances in the form of interaction with the environment and tool-like end-effector perturbations. The results demonstrated improved performance in the hybrid controller over both of its component parts. In addition, we introduce a novel method for online adaptation of learning parameters, using the fuzzy control formalism to utilise expert knowledge from the experimenter. This mechanism of meta-learning induces further improvement in performance and avoids the need for tuning through trial testing.

  10. A comparison of force control algorithms for robots in contact with flexible environments

    NASA Technical Reports Server (NTRS)

    Wilfinger, Lee S.

    1992-01-01

    In order to perform useful tasks, the robot end-effector must come into contact with its environment. For such tasks, force feedback is frequently used to control the interaction forces. Control of these forces is complicated by the fact that the flexibility of the environment affects the stability of the force control algorithm. Because of the wide variety of different materials present in everyday environments, it is necessary to gain an understanding of how environmental flexibility affects the stability of force control algorithms. This report presents the theory and experimental results of two force control algorithms: Position Accommodation Control and Direct Force Servoing. The implementation of each of these algorithms on a two-arm robotic test bed located in the Center for Intelligent Robotic Systems for Space Exploration (CIRSSE) is discussed in detail. The behavior of each algorithm when contacting materials of different flexibility is experimentally determined. In addition, several robustness improvements to the Direct Force Servoing algorithm are suggested and experimentally verified. Finally, a qualitative comparison of the force control algorithms is provided, along with a description of a general tuning process for each control method.

    In a system for optimizing crop growth, vegetation is cultivated in a contained environment, such as a greenhouse, an underground cavern or other enclosed space. Imaging equipment is positioned within or about the contained environment, to acquire spatially distributed crop growth information, and environmental sensors are provided to acquire data regarding multiple environmental conditions that can affect crop development. Illumination within the contained environment, and the addition of essential nutrients and chemicals are in turn controlled in response to data acquired by the imaging apparatus and environmental sensors, by an ''expert system'' which is trained to analyze and evaluate crop conditions. The expert system controls the spatial and temporal lighting pattern within the contained area, and the timing and allocation of nutrients and chemicals to achieve optimized crop development. A user can access the ''expert system'' remotely, to assess activity within the growth chamber, and can override the ''expert system''.

    2010-01-01

    Word processing was one of the earliest uses for small workstations, but we quickly learned that desktop computers were far more than e-typewriters. Similarly, "Web 2.0" capabilities, particularly advanced search engines, chats, wikis, blogs, social networking, and the like, offer tools that could significantly improve our efficiency at managing the avalanche of information and decisions needed to operate space vehicles in realtime. However, could does not necessarily equal should. We must wield two-edged swords carefully to avoid stabbing ourselves. This paper examines some Web 2.0 tools, with an emphasis on social media, and suggests which ones might be useful or harmful in real-time space operations co rnotl environments, based on the author s experience as a Payload Crew Communicator (PAYCOM) at Marshall Space Flight Center s (MSFC) Payload Operations Integration Center (POIC) for the International Space Station (ISS) and on discussions with other space flight operations control organizations and centers. There is also some discussion of an offering or two that may come from beyond the current cyber-horizon.

Observations of warm dust emission from the Galactic center were performed using the Faint Object Infrared Camera for the SOFIA Telescope (FORCAST). A dense, molecular torus referred to as the Circumnuclear Disk (CND) orbits Sgr A* with an inner radius of ~1.4 pc and extending to ~7 pc. The inner edge of the CND, which we refer to as the Circumnuclear Ring (CNR), exhibits features of a classic HII region and appears consistent with the prevailing paradigm in which the dust is heated by the Central cluster of hot, young stars. We do not detect any star formation occurring in the CNR; however, we reveal the presence of density “clumps” along the inner edge of the CNR. These clumps are not dense enough to be stable against tidal shear from Sgr A* and will be sheared out before completing a full orbit 10^5 yrs). Three Luminous Blue Variables (LBVs) are located in and near the Quintuplet Cluster 40 pc in projection from Sgr A*: qF362, the Pistol star, G0.120-0.048 (LBV3). FORCAST observation reveal the asymmetric, compressed shell of hot dust surrounding the Pistol Star and provide the first detection of the thermal emission from the symmetric, hot dust envelope surrounding LBV3. However, no detection of hot dust associated with qF362 is made. We argue that the Pistol star and LBV3 are identical “twins” that exhibit contrasting nebulae due to the external influence of their different environments. G-0.02-0.07, a complex consisting of three compact HII regions and one ultracompact HII region, is located at the edge of a molecular cloud 6 pc in projection to the east of Sgr A* and contains the most recent episode of star formation in the Galactic center. We probe the dust morphology, energetics, and composition of the regions to study the star forming conditions of a molecular

    Providing a controlled environment for growth of plants in a space environment involves development of unique technologies for the various subsystems of the plant growing facility. These subsystems must be capable of providing the desired environmental control within the operational constraints of currently available space vehicles, primarily the US Space Shuttle or the Russian Space Station, MIR. These constraints include available electrical power, limited total payload mass, and limited volume of the payload. In addition, the space hardware must meet safety requirements for a man-rated space vehicle. The ASTROCULTURE (TM) space-based plant growth unit provides control of temperature, humidity, and carbon dioxide concentration of the plant chamber air. A light emitting diode (LED) unit provides red and blue photons with a total intensity adjustable from 0 to 500 micromoles m-2 s-1. Ethylene released by the plant material is removed with a non-consumable ethylene removable unit. A porous tube and rooting matrix subsystem is used to supply water and nutrients to the plants. The ASTROCULTURE(TM) flight unit is sized to be accommodated in a single middeck locker of the US Space Shuttle, the SPACEHAB module, and with slight modification in the SPACELAB module. The environmental control capabilities of the subsystems used in the ASTROCULTURE(TM) flight unit have been validated in a microgravity environment during five US Space Shuttle missions, including two with plants. The unique environmental control technologies developed for the space-based plant growth facility can be used to enhance the environmental control capabilities of terrestrial controlled environment plant chambers.

    Cognitive-performance and motor-performance activities in multi-task, high-workload environments were assessed during astronaut performance in space flight and in isolation. Data was collected in microgravity on the International Micro-gravity Laboratory (IML) space shuttle mission (STS-42), and the Canadian Astronaut Program Space Unit Life Simulation (CAPSULS) mission offered an ideal opportunity to collect data for individuals in extreme isolation to complement the space flight data using similar hardware, software, and experimental protocols. The mental workload and performance experiment (MWPE) was performed during the IML-1 space flight mission, and the memory processes and motor control (MEMO) experiment was performed during the CAPSULS isolation mission. In both experiments, short-term exhaustive memory and fine motor control associated with human-computer interaction was studied. Memory processes were assessed using a Sternberg-like exhaustive memory search containing 1, 2, 4, or 7 letters. Fine motor control was assessed using velocity-controlled (joystick) and position-controlled (trackball) computer input devices to acquire targets as displayed on a computer screen. Subjects repeated the tasks under two conditions that tested perceptual motor adaptation strategies: 1) During adaptation to the microgravity environment; and 2) While wearing left-right reversing prism goggles during the CAPSULS mission. Both conditions significantly degraded motor performance but not cognitive performance. The data collected during both the MEMO experiment and the MWPE experiments enhance the knowledge base of human interface technology for human performance in extreme environments.

    1994-01-01

    An automated environment with hardware-in-the-loop has been developed by Rocketdyne Huntsville for test of a real-time control system. The target system of application is the man-rated real-time system which controls the Space Shuttle Main Engines (SSME). The primary use of the environment is software verification and validation, but it is also useful for evaluation and analysis of SSME avionics hardware and mathematical engine models. It provides a test bed for the integration of software and hardware. The principles and skills upon which it operates may be applied to other target systems, such as those requiring hardware-in-the-loop simulation and control system development. Potential applications are in problem domains demanding highly reliable software systems requiring testing to formal requirements and verifying successful transition to/from off-nominal system states.

    The changing face of contemporary military conflicts has forced a major shift of focus in tactical planning and evaluation from the classical Cold War battlefield to an asymmetric guerrilla-type warfare in densely populated urban areas. The new arena of conflict presents unique operational difficulties due to factors like complex mobility restrictions and the necessity to preserve civilian lives and infrastructure. In this paper we present a novel method for autonomous agent control in an urban environment. Our approach is based on fusing terrain information and agent goals for the purpose of transforming the problem of navigation in a complex environment with many obstacles into the easier problem of navigation in a virtual obstacle-free space. The main advantage of our approach is its ability to act as an adapter layer for a number of efficient agent control techniques which normally show poor performance when applied to an environment with many complex obstacles. Because of the very low computational and space complexity at runtime, our method is also particularly well suited for simulation or control of a huge number of agents (military as well as civilian) in a complex urban environment where traditional path-planning may be too expensive or where a just-in-time decision with hard real-time constraints is required.

    This paper presents an extreme environment capable Distributed Motor Controller (DMC) module suitable for operation with a distributed architecture of future spacecraft systems. This motor controller is designed to be a bus-based electronics module capable of operating a single Brushless DC motor in extreme space environments: temperature (-120 C to +85 C required, -180 C to +100 C stretch goal); radiation (>;20K required, >;100KRad stretch goal); >;360 cycles of operation. Achieving this objective will result in a scalable modular configuration for motor control with enhanced reliability that will greatly lower cost during the design, fabrication and ATLO phases of future missions. Within the heart of the DMC lies a pair of cold-capable Application Specific Integrated Circuits (ASICs) and a Field Programmable Gate Array (FPGA) that enable its miniaturization and operation in extreme environments. The ASICs are fabricated in the IBM 0.5 micron Silicon Germanium (SiGe) BiCMOS process and are comprised of Analog circuitry to provide telemetry information, sensor interface, and health and status of DMC. The FPGA contains logic to provide motor control, status monitoring and spacecraft interface. The testing and characterization of these ASICs have yielded excellent functionality in cold temperatures (-135 C). The DMC module has demonstrated successful operation of a motor at temperature.

    The Network Operations Control Center (NOCC) of the DSN is responsible for scheduling the resources of DSN, and monitoring all multi-mission spacecraft tracking activities in real-time. Operations performs this job with computer systems at JPL connected to over 100 computers at Goldstone, Australia and Spain. The old computer system became obsolete, and the first version of the new system was installed in 1991. Significant improvements for the computer-human interfaces became the dominant theme for the replacement project. Major issues required innovating problem solving. Among these issues were: How to present several thousand data elements on displays without overloading the operator? What is the best graphical representation of DSN end-to-end data flow? How to operate the system without memorizing mnemonics of hundreds of operator directives? Which computing environment will meet the competing performance requirements? This paper presents the technical challenges, engineering solutions, and results of the NOCC computer-human interface design.

    2014-01-01

    Dynamic flight environments in which objectives and environmental features change with respect to time pose a difficult problem with regards to planning optimal flight paths. Path planning methods are typically computationally expensive, and are often difficult to implement in real time if system objectives are changed. This computational problem is compounded when multiple agents are present in the system, as the state and action space grows exponentially. In this work, we use cooperative coevolutionary algorithms in order to develop policies which control agent motion in a dynamic multiagent unmanned aerial system environment such that goals and perceptions change, while ensuring safety constraints are not violated. Rather than replanning new paths when the environment changes, we develop a policy which can map the new environmental features to a trajectory for the agent while ensuring safe and reliable operation, while providing 92% of the theoretically optimal performance

    The prevalence of chronic kidney disease continues to increase worldwide, especially in our country with a consequent increase in patients requiring renal replacement therapy by hemodialysis, either temporarily or for life in the absence of a solid draft kidney transplant in the future. However, hemodialysis and peritoneal dialysis treatment are very expensive, very demanding in resources such as water and electricity and generate a large amount of waste. The objective of our work is to put the item in the environmental aspects of dialysis and its impact on the environment. This is a descriptive cross-sectional study conducted in the department of nephrology dialysis. Our hemodialysis center has 13 generators with a private water treatment (mono osmosis). Our annual water consumption for a single hemodialysis generator for 10hours per day and 6days per week is estimated at 93.6m(3). The production volume of water discharged from the reverse osmosis system (concentrate rejected) is 12m(3)/day (66% of the volume of water treated by reverse osmosis) with physico-chemical and bacteriological parameters remaining in the standards of WHO/FAO irrigation potential. The living water treatment as well as our 13 generators need more than 156 KW/day for work. The waste generated is about 23.5 tons/year, classified as high risk because of the high rates of hepatitis C in our center (48%) and severity of bacterial flora that we have identified in the post-generator dialysate thrown directly into sewers. Our natural resources are valuable especially that we are among the world exposed to water shortages in the near future (Haut-Commissariat des eaux et forêts et à la désertification du Maroc, 2009), which leads us to develop new programs to recycle waste and rejected in order to concentrate the reuse in various areas (irrigation, watering, sanitation, sterilization of surgical instruments), and to encourage the use of solar energy especially in a sunny country like ours.

    Presented is a collaborative project carrying out by joint team of researchers from the Institute of Monitoring of Climatic and Ecological Systems, Russia and Earth Systems Research Center, University of New Hampshire, USA. Its main objective is development of a hardware and software prototype of Distributed Research Center (DRC) for monitoring and projecting of regional climatic and and their impacts on the environment over the Northern extratropical areas. In the framework of the project new approaches to "cloud" processing and analysis of large geospatial datasets (big geospatial data) are being developed. It will be deployed on technical platforms of both institutions and applied in research of climate change and its consequences. Datasets available at NCEI and IMCES include multidimensional arrays of climatic, environmental, demographic, and socio-economic characteristics. The project is aimed at solving several major research and engineering tasks: 1) structure analysis of huge heterogeneous climate and environmental geospatial datasets used in the project, their preprocessing and unification; 2) development of a new distributed storage and processing model based on a "shared nothing" paradigm; 3) development of a dedicated database of metadata describing geospatial datasets used in the project; 4) development of a dedicated geoportal and a high-end graphical frontend providing intuitive user interface, internet-accessible online tools for analysis of geospatial data and web services for interoperability with other geoprocessing software packages. DRC will operate as a single access point to distributed archives of spatial data and online tools for their processing. Flexible modular computational engine running verified data processing routines will provide solid results of geospatial data analysis. "Cloud" data analysis and visualization approach will guarantee access to the DRC online tools and data from all over the world. Additionally, exporting of data

    This summer I was given the opportunity to work at the Habitability Design Center (HDC). NASA Johnson Space Center's HDC is currently developing Cislunar and Mars spacecraft mockups. I contributed to this effort by designing from scratch low cost, functional translational hand controllers (THCs) that will be used in spacecraft mission simulation in low to medium fidelity exploration spacecraft mockups. This project fell under the category of mechatronics, a combination of mechanical, electrical, and computer engineering. Being an aerospace engineering student, I was out of my comfort zone. And that was a wonderful thing. The autonomy that my mentor, Dr. Robert Howard, allowed me gave me the opportunity to learn by trying, failing, and trying again. This project was not only a professional success for me, but a significant learning experience. I appreciated the freedom that I had to take the time to learn new things for myself rather than blindly follow instructions. I was the sole person working on this project, and was required to work independently to solve the many hardware and software challenges that the project entailed. I researched THCs that have been used on the ISS, the Space Shuttle, and the Orion MPVC and based my design off of these. I worked through many redesigns before finding an optimal configuration of the necessary mechanisms and electrical components for the THC. Once I had a functional hardware design, I dove into the challenge of getting an Arduino Uno, an extremely low cost and easily programmable microcontroller, to behave as a human interface device. The THCs I built needed to be able to integrate to a mission simulation designed by NASA's Graphics and Visualization Lab. This proved to be the most challenging aspect of the project. To accomplish this I learned how to change the firmware of the USB serial converter microcontroller. The process was very complicated as it involved multiple software programs and manual flashing of pins on the

    We present the development of a stochastic control strategy that leverages the environmental dynamics and uncertainty to navigate in a stochastic fluidic environment. We assume that the domain is composed of the union of a collection of disjoint regions, each bounded by Lagrangian coherent structures (LCSs). We analyze a passive particle's noise-induced transition between adjacent LCS-bounded regions and show how most probable escape trajectories with respect to the transition probability between adjacent LCS-bounded regions can be determined. Additionally, we show how the likelihood of transition can be controlled through minimal actuation. The result is an energy efficient navigation strategy that leverages the inherent uncertainty of the surrounding flow field for controlling sensors in a noisy fluidic environment. We experimentally validate the proposed control strategy and show that the single vehicle control parameter exhibits a predictable exponential scaling with respect to the escape times and is effective even in situations where the structure of the flow is not fully known and control effort is costly.

    In December 1990 the Investigation and Prevention Branch, Hospital Infections Program, Centers for Disease Control and Prevention (CDC), developed the Hospital Infections Program infection control information system (HIP ICIS) to respond more efficiently to more than 200 public inquiries (telephone or written) that HIP receives daily. The HIP ICIS allows anyone with a Touch-Tone telephone, fax machine, or computer to access CDC information that answers the most commonly asked questions from infection control practitioners and other health care workers. The HIP ICIS has received approximately 56,608 inquiries; of these, 33% were about CDC guidelines on prevention and control of nosocomial infections, 25% about issues related to HIV, 16% about sterilization and disinfection of medical devices, 8% about methicillin-resistant Staphylococcus aureus, 3% about long-term care facilities, and 17% miscellaneous topics (e.g., nosocomial infection rates, infection control courses, and ventilation, construction, and renovation of hospitals). The HIP ICIS is an efficient method of providing infection control guidance to the infection control community. In this article, we a) review the history of the HIP ICIS, b) present data on HIP ICIS usage, c) summarize the current HIP ICIS contents, and d) present step-by-step instructions on how to access the HIP ICIS.

    OBJECTIVES. The study's objectives were to assess (1) control of a community outbreak of shigellosis through the promotion of handwashing, (2) risk factors in day-care centers, and (3) shigellosis attributable to attendance at a day-care center. METHODS. In 1991, an outbreak of Shigella sonnei infections occurred in Lexington-Fayette County, Ky; 14 licensed child day-care centers were involved. Communitywide promotion of hand washing was instituted along with diarrhea surveillance. A case-control study compared day-care centers that had confirmed cases of shigellosis with centers that had none. A family transmission study determined those cases attributable to attendance at day-care centers. RESULTS. The outbreak abated 3 weeks after the interventions' initiation. Day-care centers with outbreaks were more likely than those with no cases to have a food handler who changed diapers and to provide transportation for children from their homes to the center. These centers also had a higher toddler-to-toilet ratio than control centers (21 vs 12). In 58% of families with shigellosis, the first person with diarrhea during the outbreak was a child younger than 6 years; 92% of diarrheal illnesses among these children were attributable to day-care attendance. CONCLUSIONS. Community involvement in increasing hand washing most likely resulted in control of this shigellosis outbreak. Diarrhea prevention strategies in day-care centers could prevent substantial communitywide disease. PMID:7762715

    Virtual environments for software visualization may enable complex programs to be created and maintained. A typical application might be for control of regional electric power systems. As these encompass broader computer networks than ever, construction of such systems becomes very difficult. Conventional text-oriented environments are useful in programming individual processors. However, they are obviously insufficient to program a large and complicated system, that includes large numbers of computers connected to each other; such programming is called 'programming in the large.' As a solution for this problem, the authors are developing a graphic programming environment wherein one can visualize complicated software in virtual 3D world. One of the major features of the environment is the 3D representation of concurrent process. 3D representation is used to supply both network-wide interprocess programming capability (capability for 'programming in the large') and real-time programming capability. The authors' idea is to fuse both the block diagram (which is useful to check relationship among large number of processes or processors) and the time chart (which is useful to check precise timing for synchronization) into a single 3D space. The 3D representation gives us a capability for direct and intuitive planning or understanding of complicated relationship among many concurrent processes. To realize the 3D representation, a technology to enable easy handling of virtual 3D object is a definite necessity. Using a stereo display system and a gesture input device (VPL DataGlove), our prototype of the virtual workstation has been implemented. The workstation can supply the 'sensation' of the virtual 3D space to a programmer. Software for the 3D programming environment is implemented on the workstation. According to preliminary assessments, a 50 percent reduction of programming effort is achieved by using the virtual 3D environment. The authors expect that the 3D

  4. The Student-Centered Active Learning Environment for Undergraduate Programs (SCALE-UP) Project

    How do you keep a classroom of 100 undergraduates actively learning? Can students practice communication and teamwork skills in a large class? How do you boost the performance of underrepresented groups? The Student-Centered Active Learning Environment for Undergraduate Programs (SCALE-UP) Project has addressed these concerns. Because of their inclusion in a leading introductory physics textbook, project materials are used by more than 1/3 of all science, math, and engineering majors nationwide. The room design and pedagogy have been adopted at more than 100 leading institutions across the country. Physics, chemistry, math, astronomy, biology, engineering, earth sciences, and even literature classes are currently being taught this way. Educational research indicates that students should collaborate on interesting tasks and be deeply involved with the material they are studying. We promote active learning in a redesigned classroom for 100 students or more. (Of course, smaller classes can also benefit.) Class time is spent primarily on "tangibles" and "ponderables"--hands-on activities, simulations, and interesting questions. Nine students sit in three teams at round tables. Instructors circulate and engage in Socratic dialogues. The setting looks like a banquet hall, with lively interactions nearly all the time. Hundreds of hours of classroom video and audio recordings, transcripts of numerous interviews and focus groups, data from conceptual learning assessments (using widely-recognized instruments in a pretest/posttest protocol), and collected portfolios of student work are part of our rigorous assessment effort. Our findings (based on data from over 16,000 students collected over five years as well as replications at adopting sites) can be summarized as the following: 1) Female failure rate is 1/5 of previous levels, even though more is demanded of students. 2) Minority failure rate is 1/4 that seen in traditionally taught courses. 3) At-risk students are more

    Realistic models of neuromusculoskeletal systems can provide a safe and convenient environment for the design and evaluation of controllers for functional electrical stimulation (FES) prior to clinical trials. We have developed a set of integrated musculoskeletal modeling tools to facilitate the model building process. Simulink models of musculoskeletal systems are created using two software packages developed in our laboratory, Musculoskeletal Modeling in Simulink (MMS) and virtual muscle, in addition to one software package available commercially, SIMM (Musculographics Inc., USA). MMS converts anatomically accurate musculoskeletal models generated by SIMM into Simulink(R) blocks. It also removes run-time constraints on kinetic simulations in SIMM, and allows the development of complex musculoskeletal models without writing a line of code. Virtual muscle builds realistic Simulink models of muscles responding to either natural recruitment or FES. Models of sensorimotor control systems can be developed using various Matlab (Mathworks Inc., USA) toolboxes and integrated easily with these musculoskeletal blocks in the graphical environment of Simulink.

    The relationship between hand preference and duration of sleep was assessed in 40 healthy subjects using self-report estimates, sleep diaries, and wrist activity monitors during an uncontrolled 7-day at-home phase and during a controlled overnight stay in a sleep laboratory. Handedness was unrelated to any index of sleep duration when assessed in the unregulated home environment. In the controlled environment of the laboratory, however, greater right-hand dominance was positively correlated with more minutes of obtained sleep and greater sleep efficiency. Findings were consistent with previous reports which suggest measures of brain lateralization may be related to sleep and health but further suggest that these relationships may be easily obscured by extraneous environmental factors when assessed in an uncontrolled setting.

    2001-01-01

    As organizations begin to deploy large computational grids, it has become apparent that systems for observation and control of the resources, services, and applications that make up such grids are needed. Administrators must observe the operation of resources and services to ensure that they are operating correctly and they must control the resources and services to ensure that their operation meets the needs of users. Further, users need to observe the performance of their applications so that this performance can be improved and control how their applications execute in a dynamic grid environment. In this paper we describe our software framework for control and observation of resources, services, and applications that supports such uses and we provide examples of how our framework can be used.

    School-Based Health Centers (SBHCs) have improved access to primary and preventive health care for underserved children and youth by bringing comprehensive health services into the schools while addressing critical health problems that make it difficult for students to learn. Despite the findings on the positive effects of SBHCs on health outcomes, the literature investigating the relationship between SBHCs and the learning environment is scant. This study utilizes a quasi experimental study to investigate the moderating effects of school type on the relationship between school based health centers and the learning environment. Findings indicate that SBHCs in middle and elementary schools are associated with greater levels of school engagement and satisfaction with the learning environment than those in high schools.

  1. Mist control at a machining center, Part 2: Mist control following installation of air cleaners.

    PubMed

    Yacher, J M; Heitbrink, W A; Burroughs, G E

    2000-01-01

    At a machining center used to produce transaxle and transmission parts, aerosol instrumentation was used to quantitatively evaluate size-dependent mist generation of a synthetic metalworking fluid (MWF) consisting primarily of water and triethanolamine (TEA). This information was used to select an air cleaner for controlling the mist. During most machining operations, the MWF was flooded over the part. These machining operations were performed in a nearly complete enclosure that was exhausted to an air cleaner consisting of three sections: a fall-out chamber, a trifilter section to capture metal chips and mist, and a 1.13 m3/sec (2400 ft3/min) blower. The partnering company requested that National Institute for Occupational Safety and Health (NIOSH) researchers perform an evaluation of the effectiveness of a commercially available air cleaner. After NIOSH researchers characterized mist generation at the machining centers and found that performance of a test air cleaner appeared to be suitable, the company installed more than 25 air cleaners on different machining centers in this plant and enclosed the corresponding fluid filtration unit. The facility also has implemented a maintenance program for the air cleaners that involves regularly scheduled filter changes; performance is ensured by monitoring static pressure. A NIOSH-conducted air sampling evaluation showed that area TEA concentrations were reduced from a geometric mean of 0.25 to 0.03 mg/m3. Personal total particulate concentrations were reduced from a geometric mean of 0.22 to 0.06 mg/m3. These results show the effectiveness of this combination of enclosure, ventilation, and filtration to greatly reduce the exposure to MWF mist generated in modern machining centers.

    A state-of-the-art computational facility for aircraft flight control design, evaluation, and integration called CONDUIT (Control Designer's Unified Interface) has been developed. This paper describes the CONDUIT tool and case study applications to complex rotary- and fixed-wing fly-by-wire flight control problems. Control system analysis and design optimization methods are presented, including definition of design specifications and system models within CONDUIT, and the multi-objective function optimization (CONSOL-OPTCAD) used to tune the selected design parameters. Design examples are based on flight test programs for which extensive data are available for validation. CONDUIT is used to analyze baseline control laws against pertinent military handling qualities and control system specifications. In both case studies, CONDUIT successfully exploits trade-offs between forward loop and feedback dynamics to significantly improve the expected handling, qualities and minimize the required actuator authority. The CONDUIT system provides a new environment for integrated control system analysis and design, and has potential for significantly reducing the time and cost of control system flight test optimization.

    Department of Transportation (DOT) mandates reporting of all serious hazardous materials incidents. Hazardous material exposures may result in secondary contamination of emergency departments, or delayed clinical effects. Poison control centers specialize in the management of patients exposed to toxic substances; however, poison control center notification is not required. The objective is to determine the frequency of poison control center notification after serious hazardous materials incidents when patients were transported to a hospital. A retrospective analysis was conducted of serious hazardous materials incidents as reported by DOT, matched with data from the American Association of Poison Control Centers from 2002 through 2006 that involved patient transport. Incidents were divided into four groups: those reported to a poison control center within 0-360 minutes of the incident; those reported within 361-1440 minutes of the incident; those reported within 1441-4320 minutes of the incident; and no poison control center notification. Analyses were performed on variables including date, time, substance, and time to notification. Data were received in January 2008. One hundred fifty-four serious incidents met inclusion criteria. One hundred thirty-four incidents (87%) occurred without poison control center notification. Poison control centers were notified in 20 incidents (12.9%); 15 incidents (9.7%) were reported within 0-360 minutes of the incident (M=115 minutes, range=5-359 minutes); four incidents (2.6%) were reported within 361-1440 minutes of the incident (M=652 minutes, range=566-750 minutes); and one incident (0.7%) was reported after 4320 minutes following the incident. Most serious hazardous materials incidents involving patient transport are not reported to poison control centers. Opportunities exist to increase utilization of poison control center resources without increasing financial burdens of the hazardous materials incident. Published by

    This paper presents the process used by the Marshall Space Flight Center Natural Environments Branch (EV44) to quality control (QC) data from the Kennedy Space Center's 50-MHz Doppler Radar Wind Profiler for use in vehicle wind loads and steering commands. The database has been built to mitigate limitations of using the currently archived databases from weather balloons. The DRWP database contains wind measurements from approximately 2.7-18.6 km altitude at roughly five minute intervals for the August 1997 to December 2009 period of record, and the extensive QC process was designed to remove spurious data from various forms of atmospheric and non-atmospheric artifacts. The QC process is largely based on DRWP literature, but two new algorithms have been developed to remove data contaminated by convection and excessive first guess propagations from the Median Filter First Guess Algorithm. In addition to describing the automated and manual QC process in detail, this paper describes the extent of the data retained. Roughly 58% of all possible wind observations exist in the database, with approximately 100 times as many complete profile sets existing relative to the EV44 balloon databases. This increased sample of near-continuous wind profile measurements may help increase launch availability by reducing the uncertainty of wind changes during launch countdown

    Almost one-third of preschoolers spend regular time in child care centers where they can consume the majority of their daily dietary intake. The child care setting influences children's dietary intake. Thus, it is important to examine factors, such as local and state regulations, that influence the food environment at the center. This qualitative study explored directors' perceptions of how regulations influence the foods available at child care centers. Ten directors of centers in Travis County, Texas completed semi-structured interviews. Directors reported that changes in local health department regulations (e.g., kitchen specifications) result in less-healthful foods being served (e.g., more prepackaged foods). Directors of centers that do not participate in the federal Child and Adult Care Food Program (CACFP) said the state licensing regulations clarify the portion size and nutritional requirements for preschoolers thereby improving the nutritional quality of the food served. Directors of centers participating in CACFP said they are not affected by state mandates, because the CACFP regulations are more stringent. These findings suggest that state regulations that specify and quantify nutritional standards may beneficially impact preschoolers' diets. However, local health department regulations enacted to improve food safety may negatively influence the nutritional value of food served in centers.

    The management of organizations is responsible for risk management and control systems. HIV/AIDS could be a great threat in the achievement of strategic business objectives, implicating a great concern for management. Management needs to understand this possible risk. This study aims to identify the effect that HIV/AIDS could have on the different elements of the control environment. The archival research method was used. It was established that no formal research was conducted to date on the effect of HIV/AIDS on the control environment as a whole. Various studies have included the effect of HIV/AIDS on certain factors of the control environment. These studies will be discussed briefly to identify relevant findings. The study indicated that the disease could affect various aspects of the control environment, namely: competency of the workforce (e.g. productivity, quality of work, absenteeism, loss of skills and knowledge, training and recruitment, etc.); organizational structure (e.g. increase use of technology labour, disruption of processes, level of employees affected by the disease); human resource (HR) policies and practices (e.g. legislation applicable, prevention and awareness programmes, compensation and benefits). Research limitation: HIV/AIDS is a relatively new potential risk to organizations. Knowledge of the disease is limited. HIV/AIDS is also a very sensitive issue as people fear the disease and do not like to discuss its existence. Government determined that it should be a non-notifiable disease and the disease is currently greatly stigmatized. The databases of companies investigated by other research studies were not developed to gather all the relevant information. Management should be aware that HIV/AIDS poses a possible risk to organizations. Data on the effect of HIV/AIDS should be gathered and used in the decision-making process on how to manage this risk. To be able to fulfil this duty, management first has to determine: whether HIV/AIDS is

    Cancer is both highly feared and highly newsworthy, and there is a robust body of research documenting the content and effects of cancer news coverage on health behaviors and policy. Recent years have witnessed ongoing, transformative shifts in American journalism alongside rapid advances in communication technology and the public information environment. These changes create a pressing need to consider a new set of research questions, sampling strategies, measurement techniques, and theories of media effects to ensure continued relevance and adaptation of communication research to address critical cancer control concerns. This paper begins by briefly reviewing what we know about the role of cancer news in shaping cancer-related beliefs, attitudes, behaviors, and policies. We then outline challenges and opportunities, both theoretical and methodological, posed by the rapidly changing news media environment and the nature of audience engagement. We organize our discussion around three major shifts associated with the emerging news media environment as it relates to health communication: 1) speed and dynamism of news diffusion, 2) increased narrowcasting of media content for specialized audiences, and 3) broadened participation in shaping media content. In so doing, we articulate a set of questions for future theory and research, in an effort to catalyze innovative communication scholarship to improve cancer prevention and control.

    Singh, Bhim S.; Hasan, Mohammad H.

    2007-01-01

    Innovative multi-environment multimode thermal management architecture has been described that is capable of meeting widely varying thermal control requirements of various exploration mission scenarios currently under consideration. The proposed system is capable of operating in a single-phase or two-phase mode rejecting heat to the colder environment, operating in a two-phase mode with heat pump for rejecting heat to a warm environment, as well as using evaporative phasechange cooling for the mission phases where the radiator is incapable of rejecting the required heat. A single fluid loop can be used internal and external to the spacecraft for the acquisition, transport and rejection of heat by the selection of a working fluid that meets NASA safety requirements. Such a system may not be optimal for each individual mode of operation but its ability to function in multiple modes may permit global optimization of the thermal control system. The architecture also allows flexibility in partitioning of components between the various Constellation modules to take advantage of operational requirements in various modes consistent with the mission needs. Preliminary design calculations using R-134 as working fluid show the concept to be feasible to meet the heat rejection requirements that are representative of the Crew Exploration Vehicle and Lunar Access Module for nominal cases. More detailed analyses to establish performance under various modes and environmental conditions are underway.

    Ott-Grebogi-Yorke control and its map-based variants work by targeting the (linear) stable subspace of the target orbit so that after one application of the control the system will be in this subspace. I propose an n-step variation, where n is the dimension of the system, that sends any initial condition in a controllable region directly to the target orbit instead of its stable subspace. This method is time optimal, in that, up to modeling and measurement error, the system is completely controlled after n iterations of the control procedure. I demonstrate the procedure using a piecewise linear and a nonlinear two-dimensional map, and indicate how the technique may be extended to maps and flows of higher dimension.

    The availability of new genetic technologies has positioned the field of biological control as a test bed for theories in evolutionary biology and for understanding practical aspects of the release of genetically manipulated material. Purposeful introductions of pathogens, parasites, predators and herbivores, when considered as replicated semi-natural field experiments, show the unpredictable nature of biological colonization. The characteristics of organisms and their environments that determine this variation in the establishment and success of biological control can now be explored using genetic tools. Lessons from studies of classical biological control can help inform researchers and policy makers about the risks that are associated with the release of genetically modified organisms, particularly with respect to long-term evolutionary changes.

    2006-01-01

    The National Aeronautics and Space Administration (NASA) is embarking on a new era of Space Exploration, aimed at sending crewed spacecraft beyond Low Earth Orbit (LEO), in medium and long duration missions to the Lunar surface, Mars and beyond. The challenges of such missions are significant and will require new technologies and paradigms in vehicle design and mission operations. Current roles and responsibilities of spacecraft systems, crew and the flight control team, for example, may not be sustainable when real-time support is not assured due to distance-induced communication lags, radio blackouts, equipment failures, or other unexpected factors. Therefore, technologies and applications that enable greater Systems and Mission Management capabilities on-board the space-based system will be necessary to reduce the dependency on real-time critical Earth-based support. The focus of this paper is in such technologies that will be required to bring advance Systems and Mission Management capabilities to space-based environments where the crew will be required to manage both the systems performance and mission execution without dependence on the ground. We refer to this concept as autonomy. Environments that require high levels of autonomy include the cockpits of future spacecraft such as the Mars Exploration Vehicle, and space-based control centers such as a Lunar Base Command and Control Center. Furthermore, this paper will evaluate the requirements, available technology, and roadmap to enable full operational implementation of onboard System Health Management, Mission Planning/re-planning, Autonomous Task/Command Execution, and Human Computer Interface applications. The technology topics covered by the paper include enabling technology to perform Intelligent Caution and Warning, where the systems provides directly actionable data for human understanding and response to failures, task automation applications that automate nominal and Off-nominal task execution based

    Clinicians and researchers working with dementia caregivers typically assess caregiver stress in a clinic or research center, but caregivers' stress is rooted at home where they provide care. This study aimed to compare ratings of stress-related measures obtained in research settings and in the home using ecological momentary assessment (EMA). EMA of 18 caregivers (mean age 66.4 years ±7.8; 89% females) and 23 non-caregivers (mean age 66.4 years ±7.9; 87% females) was implemented using a personal digital assistant. Subjects rated their perceived stress, fatigue, coping with current situation, mindfulness, and situational demand once in the research center and again at 3-4 semi-random points during a day at home. The data from several assessments conducted at home were averaged for statistical analyses and compared with the data collected in the research center. The testing environment had a differential effect on caregivers and non-caregivers for the ratings of perceived stress (p < 0.01) and situational demand (p = 0.01). When tested in the research center, ratings for all measures were similar between groups, but when tested at home, caregivers rated their perceived stress as higher than non-caregivers (p = 0.02). Overall, caregivers reported higher perceived stress at home than in the research center (p = 0.02), and non-caregivers reported greater situational demand in the research center than at home (p < 0.01). The assessment method and environment affect stress-related outcomes. Evaluating participants in their natural environment provides a more sensitive measure of stress-related outcomes. EMA provides a convenient way to gather data when evaluating dementia caregivers.

  18. Controlling QoS in a collaborative multimedia environment

    A collaborative multimedia environment allows users to work remotely on common projects by sharing applications (e.g., CAD tools, text editors, white boards) and simultaneously communicate audiovisually. Several dedicated applications (e.g., MBone tools) exist for transmitting video, audio and data between users. Due to the fact that they have been developed for the Internet which does not provide any Quality of Service (QoS) guarantee, these applications do not or only partially support specification of QoS requirements by the user. In addition, they all come with different user interfaces. In this paper we first discuss the problems that we experienced both at the host and network levels when executing a multimedia application and varying its resource requirements. We then present the architectural details of a collaborative multimedia environment (CME) that we have been developing in order to help a user to set up and control a collaborative multimedia session.

    CO2 and water vapor fluxes of hydroponically grown wheat and soybean canopies were measured continuously in several environments with an open gas exchange system. Canopy CO2 fluxes reflect the photosynthetic efficiency of a plant community, and provide a record of plant growth and health. There were significant diurnal fluctuations in root and shoot CO2 fluxes, and in shoot water vapor fluxes. Canopy stomatal conductance (Gc) to water vapor was calculated from simultaneous measurements of canopy temperature (Tcan) and transpiration rates (Tr). Tr in the dark was substantial, and there were large diurnal fluctuations in both Gc and Tr. Canopy net Photosynthesis (Pnet), Tr, and Gc increased with increasing net radiation. Gc increased with Tr, suggesting that the stomata of plants in controlled environments (CEs) behave differently from field-grown plants. A transpiration model based on measurements of Gc was developed for CEs. The model accurately predicted Tr from a soybean canopy.

    The behavior in space environment of evaporated Al uncoated and coated with reactively deposited silicon oxide (SiOx), electron beam evaporated SiO2 and Al2O3, and Al and Ag coated with double layers of Al2O3 + SiOx is compared with metallized Teflon and Kapton, anodized Al (Alzak), and white paints. Flight data from three calorimetric experiments and one reflectometer flown in different orbital environments are compared with laboratory test data. The results demonstrate that evaporated thin films are extremely versatile and stable coatings for space applications. Through the use of control samples studied in different laboratory tests and monitored for up to 12,000 hours of solar exposure in different orbits, a classification of orbital severity and an estimate of laboratory simulation accuracy is obtained.

    High purity gas supply for optics purging and cleaning under vacuum is required to be maintained at the output of the mini-environment gas distribution box in EUV scanners. Typically H2 gas is used for cleaning and purging while N2 gas is used for purging H2 lines post exposure. An investigation of gas purifier performance for moisture removal is made under sub-atmospheric pressure conditions. An evaluation of moisture levels as a function of switching between H2 and N2 gas supply states is also conducted. A superior performance (below instrument LDL) is observed for HX (Entegris, Inc.) gas purifier under various test conditions in the 10-100 kPa pressure range. Our preliminary studies provide a better understanding of gas purifier related moisture outgassing under vacuum and should facilitate better control and standardization of tool set-up parameters for environment in EUV lithography.

    A methodology for designing active control laws in a computational aeroelasticity environment is given. The methodology involves employing a systems identification technique to develop an explicit state-space model for control law design from the output of a computational aeroelasticity code. The particular computational aeroelasticity code employed in this paper solves the transonic small disturbance aerodynamic equation using a time-accurate, finite-difference scheme. Linear structural dynamics equations are integrated simultaneously with the computational fluid dynamics equations to determine the time responses of the structure. These structural responses are employed as the input to a modern systems identification technique that determines the Markov parameters of an "equivalent linear system". The Eigensystem Realization Algorithm is then employed to develop an explicit state-space model of the equivalent linear system. The Linear Quadratic Guassian control law design technique is employed to design a control law. The computational aeroelasticity code is modified to accept control laws and perform closed-loop simulations. Flutter control of a rectangular wing model is chosen to demonstrate the methodology. Various cases are used to illustrate the usefulness of the methodology as the nonlinearity of the aeroelastic system is increased through increased angle-of-attack changes.

    Problems related to environmental noise are not a new subject, but they became a major issue to solve because of the increasing, in complexity and intensity, of human activities due technological advances. Numerous international studies had dealt with the exposure of critical patients to noisy environment such as the Neonatal Intensive Care Units; their results show that there are difficulties in the organization in the developing brain, it can damage the delicate auditory structures and can cause biorhythm disorders, specially in preterm infants. The objective of this paper is to present the development and implementation of a control system that includes technical-management-training aspects to regulate the levels of specific noise sources in the neonatal hospitalization environment. For this purpose, there were applied different tools like: observations, surveys, procedures, an electronic control device and a training program for a Neonatal Service Unit. As a result, all noise sources were identified -some of them are eliminable-; all the service stable staff categories participated voluntarily; environmental noise measurements yielded values between 62.5 and 64.6 dBA and maximum were between 86.1 and 89.7 dBA; it was designed and installed a noise control device and the staff is being trained in noise reduction best practices.

When applied at 8 as well as 4 days after seeding, triacontanol increased plant fresh and dry weight, leaf area, and mean relative growth rate 12% to 37%. There was no benefit of repeating application of triacontanol in terms of leaf dry weight gain.

    Space agricultural research at the Utah State University includes studies of wheat growth in a controlled environment life support system. Wheat was chosen as a candidate for research in bioregenerative systems because it can be processed into a variety of foods, it is an efficient producer, it is a major world food crop, much is known about wheat genetics and breeding, it grows well in continuous light, and converts energy into a high grain yield. Studies examine quantum yield and short-term photosynthesis, growth rates, yield and harvest index, plant density and light intensity, carbon dioxide concentrations, and breeding wheat for space agriculture.

    The overall objective of the SCEAS project was to integrate advanced greenhouse agriculture technology with various energy sources and innovative cooling/ventilation concepts to demonstrate technical and economic feasibility of these facilities in several climatic regions where conventional greenhouse technology will not permit yearround growing of certain crops. The designed facility is capable of high yields of practically any crop, even temperaturesensitive vegetables such as lettuce, in extremely hostile external environments. The recirculation and ventilation system provides considerable flexibility in precise control of temperature and humidity throughout the year and in reducing water and energy consumption.

    The functions of metal complexes are directly linked to the local environment in which they are housed; modifications to the local environment (or secondary coordination sphere) are known to produce changes in key properties of the metal centers that can affect reactivity. Noncovalent interactions are the most common and influential forces that regulate the properties of secondary coordination spheres, which leads to complexities in structure that are often difficult to achieve in synthetic systems. Using key architectural features from the active sites of metalloproteins as inspiration, we have developed molecular systems that enforce intramolecular hydrogen bonds (H-bonds) around a metal center via incorporation of H-bond donors and acceptors into rigid ligand scaffolds. We have utilized these molecular species to probe mechanistic aspects of biological dioxygen activation and water oxidation. This Account describes the stabilization and characterization of unusual M-oxo and heterobimetallic complexes. These types of species have been implicated in a range of oxidative processes in biology but are often difficult to study because of their inherent reactivity. Our H-bonding ligand systems allowed us to prepare an Fe(III)-oxo species directly from the activation of O2 that was subsequently oxidized to form a monomeric Fe(IV)-oxo species with an S = 2 spin state, similar to those species proposed as key intermediates in non-heme monooxygenases. We also demonstrated that a single Mn(III)-oxo center that was prepared from water could be converted to a high-spin Mn(V)-oxo species via stepwise oxidation, a process that mimics the oxidative charging of the oxygen-evolving complex (OEC) of photosystem II. Current mechanisms for photosynthetic O-O bond formation invoke a Mn(IV)-oxyl species rather than the isoelectronic Mn(V)-oxo system as the key oxidant based on computational studies. However, there is no experimental information to support the existence of a Mn

    location). Each digital entity that is ingested into the SCEC community library is processed and validated for conformance to SCEC standards. These steps generate provenance, descriptive, administrative, structural, and behavioral metadata. Using data grid technology, the descriptive metadata can be registered onto a logical name space that is controlled and managed by the SCEC digital library. A version of the SCEC community digital library is being implemented in the Storage Resource Broker. The SRB system provides almost all the features enumerated above. The peer-to-peer federation of metadata catalogs is planned for release in September, 2003. The SRB system is in production use in multiple projects, from high-energy physics, to astronomy, to earth systems science, to bio-informatics. The SCEC community library will be based on the definition of standard metadata attributes, the creation of logical collections within the SRB, the creation of access services, and the demonstration of a preservation environment. The use of the SRB for the SCEC digital library will sustain the expected collection size and collection capabilities.
