    The Lidar In-Space Technology Experiment (LITE) is being developed by NASA/Langley Research Center for a series off lights on the space shuttle beginning in 1994. Employing a three-wave-length ND:YAG laser and a 1-m-diameter telescope, the system is a test-bed for the development of technology required for future operational spaceborne lidars. The system has been designed to observe clouds, tropospheric and stratospheric aerosols, characteristics of the planetary boundary layer, and stratospheric density and temperature perturbations with much greater resolution than is available from current orbiting sensors. In addition to providing unique datasets on these phenomena, the data obtained will be useful in improving retrieval algorithms currently in use. Observations of clouds and the planetary boundary layer will aid in the development of global climate model (GCM) parameterizations. This article briefly describes the LITE program and discusses the types of scientific investigations planned for the first flight.

    This paper presents the results of the modal survey test of the Lidar In-space Technology Experiment (LITE), a Space Shuttle payload mounted in a Spacelab flight single pallet. The test was performed by the Dynamics Test Branch at Marshall Space Flight Center, AL and run in two phases. In the first phase, an unloaded orthogrid connected to the pallet with 52 tension struts was tested. This test included 73 measurement points in three directions. In the second phase, the pallet was integrated with mass simulators mounted on the flight support structure to represent the dynamics (weight and center of gravity) of the various components comprising the LITE experiment and instrumented at 213 points in 3 directions. The test article was suspended by an air bag system to simulate a free-free boundary condition. This paper presents the results obtained from the testing and analytical model correlation efforts. The effect of the suspension system on the test article is also discussed.

    2004-12-01

    Hands-on, inquiry-based, constructivist activity offers students a powerful way to explore, uncover and ultimately gain a feel for the nature of science. In order to make practicable a more genuine approach to learning astronomy, we have undertaken the development of hands-on (and eyes-on) materials that can be used in introductory undergraduate astronomy courses. These materials focus on light and optics. Over the past several years as part of Project LITE (Light Inquiry Through Experiments), we have developed a kit of optical materials that is integrated with a set of Java applets. The combined kit and software allows students to do actual experiments concerning geometrical optics, fluorescence, phosphorescence, polarization and other topics by making use of the photons that are emitted by their computer screens. We have also developed a suite of over 100 Flash applets that allow students to directly explore many aspects of visual perception. A major effort of the project concerns spectroscopy, since it is arguably the most important tool used by astronomers to disentangle the nature of the universe. It is also one of the most challenging subjects to teach in undergraduate astronomy courses. The spectroscopy component of Project LITE includes take-home laboratory materials and experiments that are integrated with web-based software. We have also developed a novel quantitative handheld binocular spectrometer (patent pending). Our major spectroscopic software is called the Spectrum Explorer (SPEX). It allows students to create, manipulate and explore all types of spectra including blackbody, power law, emission and absorption. We are now extending the SPEX capabilities to help students gain easy access to the astronomical spectra included in the NVO databases. All of the Project LITE software can be found http://lite.bu.edu. Project LITE is supported by Grant #DUE-0125992 from the NSF Division of Undergraduate Education.

    Full Text Available Exelis has recently developed a novel laser-based instrument to aid in the autonomous real-time monitoring and mapping of CO2 concentration over a two-dimensional area. The Greenhouse gas Laser Imaging Tomography Experiment (GreenLITE instrument uses two transceivers and a series of retroreflectors to continuously measure the differential transmission over a number of overlapping lines of sight or “chords”, forming a plane. By inverting the differential transmission measurements along with locally measured temperature (T, pressure (P and relative humidity (RH the average concentration of CO2 along each chord can be determined and, based on the overlap between chords, a 2D map of CO2 concentration over the measurement plane can be estimated. The GreenLITE system was deployed to the Zero Emissions Research and Technology (ZERT center in Bozeman, Montana, in Aug-Sept 2014, where more than 200 hours of data were collected over a wide range of environmental conditions, while utilizing a controlled release of CO2 into a segmented underground pipe [1]. The system demonstrated the ability to identify persistent CO2 sources at the test facility and showed strong correlation with an independent measurement using a LI-COR based system. Here we describe the measurement approach, instrument design, and results from the deployment to the ZERT site.

    This report describes the development and testing of a novel system, the Greenhouse gas Laser Imaging Tomography Experiment (GreenLITE), for Monitoring, Reporting and Verification (MRV) of CO2 at Geological Carbon Storage (GCS) sites. The system consists of a pair of laser based transceivers, a number of retroreflectors, and a set of cloud based data processing, storage and dissemination tools, which enable 2-D mapping of the CO2 in near real time. A system was built, tested locally in New Haven, Indiana, and then deployed to the Zero Emissions Research and Technology (ZERT) facility in Bozeman, MT. Testing at ZERT demonstrated the ability of the GreenLITE system to identify and map small underground leaks, in the presence of other biological sources and with widely varying background concentrations. The system was then ruggedized and tested at the Harris test site in New Haven, IN, during winter time while exposed to temperatures as low as -15 °CºC. Additional testing was conducted using simulated concentration enhancements to validate the 2-D retrieval accuracy. This test resulted in a high confidence in the reconstruction ability to identify sources to tens of meters resolution in this configuration. Finally, the system was deployed for a period of approximately 6 months to an active industrial site, Illinois Basin – Decatur Project (IBDP), where >1M metric tons of CO2 had been injected into an underground sandstone basin. The main objective of this final deployment was to demonstrate autonomous operation over a wide range of environmental conditions with very little human interaction, and to demonstrate the feasibility of the system for long term deployment in a GCS environment.

    The ATLAS experiment has been running continuous simulated events production since more than two years. A considerable fraction of the jobs is daily submitted and handled via the gLite Workload Management System, which overcomes several limitationsof the previous LCG Resource Broker. The gLite WMS has been tested very intensively for the LHC experiments use cases for more than six months, both in terms of performance and reliability. The tests were carried out by the LCG Experiment Integration Support team (in close contact with the experiments) together with the EGEE integration and certification team and the gLite middleware developers. A pragmatic iterative and interactive approach allowed a very quick rollout of fixes and their rapid deployment, together with new functionalities, for the ATLAS production activities. The same approach is being adopted for other middleware components like the gLite and CREAM Computing Elements. In this contribution we will summarize the learning from the gLite WMS testing a...

    The LHC experiments will study the physics of p-p interactions at a centre-of-mass energy of 14 TeV using the LHC accelerator at CERN. The primary purpose of their research is the discovery of the Higgs boson and of new physics at the TeV scale. The LHC experiments are undoubtedly the most demanding communities for the EGEE infrastructure. They have thousands of collaborators who expect to run their physics analyses on the data that will be collected starting from late 2007. It is expected that each experiment will need to run hundreds of thousands of jobs per day, including: event reconstruction from raw data, analysis on reconstructed data, and Monte Carlo simulation. The management of such amounts of jobs is an extremely complicated task and the gLite WMS is being considered as a candidate to perform it. This report describes the experience of the ATLAS and the CMS experiments using the gLite Workload Management System as a tool to submit both simulation and analysis jobs. In fact, this experience has led ...

    The Limb-Imaging Ionospheric and Thermospheric Extreme-ultraviolet Spectrograph (LITES) was launched as part of the Space Test Program Houston #5 (STP-H5) payload aboard a commercial resupply flight on February 19, 2017 and was subsequently installed on the International Space Station (ISS). LITES is an imaging spectrograph that spans the 60 - 140 nm wavelength range at 1 nm spectral resolution and samples tangent altitudes 150 - 350 km with 0.2° angular resolution. LITES, in combination with the GPS Radio Occultation and Ultraviolet Photometry - Colocated (GROUP-C) experiment, which includes a GPS receiver and a nadir viewing 135.6 nm photometer, jointly collect new information on the thermosphere and the ionosphere using simultaneous UV and radio emissions. LITES, which uses standard stars to perform in-flight calibration, observes altitude profiles of day and night airglow emissions that are being used to infer thermospheric and ionospheric density profiles. Furthermore, due to the inclination of the ISS, LITES has also observed auroral spectrum and their altitude and spatial variations. Finally, geomagnetic storm effects on its UV emissions can be used to remotely sense their effects on the upper atmospheric morphology. These ISS observations,which are complement to the upcoming ICON and GOLD NASA missions, are focused on ionosphere-atmosphere coupling and global-scale atmospheric response to space weather observed from higher altitudes . We will present an overview of the LITES instrument, some early results from the first few months of operations. We will also summarize the advantages in calibration and validation activities that are possible through space-based LITES, GROUP-C and stellar measurements and simultaneous ground-based optical and radar observations.

    Roettker, William

    1995-01-01

    The Lidar In-Space Technology Experiment (LITE) was developed at NASA s Langley Research Center to explore the applications of lidar operated from an orbital platform. As a technology demonstration experiment, LITE was developed to gain experience designing and building future operational orbiting lidar systems. Since LITE was the first lidar system to be flown in space, an important objective was to validate instrument design principles in such areas as thermal control, laser performance, instrument alignment and control, and autonomous operations. Thermal and structural analysis models of the instrument were developed during the design process to predict the behavior of the instrument during its mission. In order to validate those mathematical models, extensive engineering data was recorded during all phases of LITE's mission. This inflight engineering data was compared with preflight predictions and, when required, adjustments to the thermal and structural models were made to more accurately match the instrument s actual behavior. The results of this process for the thermal analysis and design of LITE are presented in this paper.

  17. The Project LITE Spectrum Explorer

    Brecher, K.; Carr, P.; Garik, P.; Weeks, E.

    2002-12-01

    We are developing a powerful new software tool which can help students at all levels understand the spectral properties of light. As a recent AAS survey of astronomy faculty members found (The Physics Teacher, 39, 52, 2001), essentially all introductory astronomy courses spend a significant amount of time dealing with the nature of light. Among the most difficult concepts for students to master are Kirchhoff's laws, blackbody radiation, the Stefan-Boltzmann law, Wien's law, the nature and causes of emission and absorption lines, and the relation of spectra to the underlying astronomical and physical processes producing them. Students often seem baffled by the connection between a spectrum seen visually as a color band and the same spectrum plotted graphically as intensity versus wavelength or frequency. The "Spectrum Explorer", a JAVA applet, is being developed as part of "Project LITE: Light Inquiry Through Experiments" to address these issues. It can be used by instructors in lecture presentations and by students learning at home or working in laboratory settings. We will show some of the current capabilities of the software which include simultaneous display of multiple spectra (normalized and non-normalized as a function of either wavelength or frequency) and the ability to manipulate blackbody spectra. Our future development plans include the addition of a variety of spectral data sets (from physics and chemistry as well as from astronomy); computed inputs from basic quantum mechanics (e.g. Zeeman effect in hydrogen) and from astronomical models (e.g. time varying spectra in binary stars); and the ability to test the effect of filters and physical processes (e.g. Rayleigh scattering) on input spectra. The Spectrum Explorer (along with many other applets about both the physical and perceptual nature of light) can be found on the Project LITE web site http://lite.bu.edu.

    SIM Lite Astrometric Observatory, a space borne mission to be located in a solar Earth-trailing orbit, will conduct high precision differential astrometry. During the 5-year mission, SIM Lite will search about 60 nearby Sun-like stars for exoplanets of mass down to one Earth mass, in the Habitable Zone of those stars. In addition, SIM Lite will survey the architecture of planetary systems of about 1000 stars of all ages and types. SIM Lite will also build a 4 micro-arc-second astrometric grid and perform global astrometry on a variety of astrophysics objects. The instrument consists of two Michelson stellar interferometers and a precision telescope. The Science interferometer is composed of two 50 cm collectors separated by a 6 meter baseline. The technology development was completed in 2005. The mission is now ready for full flight implementation.

  19. JELC-LITE: Unconventional Instructional Design for Special Operations Training

    Science.gov (United States)

    Friedman, Mark

    2012-01-01

    Current special operations staff training is based on the Joint Event Life Cycle (JELC). It addresses operational level tasks in multi-week, live military exercises which are planned over a 12 to 18 month timeframe. As the military experiences changing global mission sets, shorter training events using distributed technologies will increasingly be needed to augment traditional training. JELC-Lite is a new approach for providing relevant training between large scale exercises. This new streamlined, responsive training model uses distributed and virtualized training technologies to establish simulated scenarios. It keeps proficiency levels closer to optimal levels -- thereby reducing the performance degradation inherent in periodic training. It can be delivered to military as well as under-reached interagency groups to facilitate agile, repetitive training events. JELC-Lite is described by four phases paralleling the JELC, differing mostly in scope and scale. It has been successfully used with a Theater Special Operations Command and fits well within the current environment of reduced personnel and financial resources.

    1976-12-08

    A one-year technology-transfer project involving ERDA installations and Hawaii consisted of sending teams from the Lawrence Livermore Laboratory on week-long field trips every two months to test the effectiveness of different methods of transferring technology information from federal sources to civilian clients. The team was questioned primarily on non-energy matters, and the energy questions asked related mostly to individuals or small industries. The team responed to all questions and found that a wide range of knowledge was more effective than having a sequence of experts. Hawaiians considered current major ERDA projects to be irrelevant to their needs. The team was most successful on a one-to-one basis because large groups and state agencies tend to be more policy- than action-oriented. Personal followup was considered essential. The team also learned that their visits generated ten times as many inquiries as were received unsolicited by the laboratory. Most inquiries involved biomass and use of agricultural wastes, solar energy, and transportation. An important contribution of the team's workshops was linking groups to work together on common problems. An appendix lists the subjects of queries and the names and addresses of consortium participants and Hawaiian contacts. (DCK)

    The MIT Space Engineering Research Center and the Jet Propulsion Laboratory stand ready to advance science sensor technology for discrete-aperture astronomical instruments such as space-based optical interferometers. The objective of the Stellar Interferometer Technology Experiment (SITE) is to demonstrate system-level functionality of a space-based stellar interferometer through the use of enabling and enhancing Controlled-Structures Technologies (CST). SITE mounts to the Mission Peculiar Experiment Support System inside the Shuttle payload bay. Starlight, entering through two apertures, is steered to a combining plate where it is interferred. Interference requires 27 nanometer pathlength (phasing) and 0.29 archsecond wavefront-tilt (pointing) control. The resulting 15 milli-archsecond angular resolution exceeds that of current earth-orbiting telescopes while maintaining low cost by exploiting active optics and structural control technologies. With these technologies, unforeseen and time-varying disturbances can be rejected while relaxing reliance on ground alignment and calibration. SITE will reduce the risk and cost of advanced optical space systems by validating critical technologies in their operational environment. Moreover, these technologies are directly applicable to commercially driven applications such as precision matching, optical scanning, and vibration and noise control systems for the aerospace, medical, and automotive sectors. The SITE team consists of experienced university, government, and industry researchers, scientists, and engineers with extensive expertise in optical interferometry, nano-precision opto-mechanical control and spaceflight experimentation. The experience exists and the technology is mature. SITE will validate these technologies on a functioning interferometer science sensor in order to confirm definitely their readiness to be baselined for future science missions.

    similarity to multiple missions. It then becomes possible to procure solar array modules in advance of mission definition and respond quickly and inexpensively to a selected mission's unique requirements. The solar array modular architecture allows the procurement of solar array modules before the array geometry has been frozen. This reduces the effect of procurement lead-time on the mission integration and test flow by as much as 50%. Second, by spreading the non-recurring costs over multiple missions, the cost per unit area is also reduced. In the case of the SMEX-Lite procurement, this reduction was by about one third of the cost per unit area compared to previous SMEX mission-unique procurements. Third, the modular architecture greatly facilitates the infusion of new solar cell technologies into flight programs as these technologies become available. New solar cell technologies need only be fabricated onto a standard-sized module to be incorporated into the next available mission. The modular solar array can be flown in a mixed configuration with some new and some standard cell technologies. Since each module has its own wiring terminals, the array can be arranged as desired electrically with little impact to cost and schedule. The solar array modular architecture does impose some additional constraints on systems and subsystem engineers. First, they must work with discrete solar array modules rather than size the array to fit exactly within an available envelope. The array area is constrained to an integer multiple of the module area. Second, the modular design is optimized for space radiation and thermal environments not greatly different from a typical SMEX LEO environment. For example, a mission with a highly elliptical orbit (e.g., Polar, SMEX/FAST) would require thicker coverglasses to protect the solar cells from the more intense radiation environment.

    Recently a new laser based approach for measuring area with potential for producing 2D estimates of the concentration spatial distribution has been developed through a cooperative agreement with the National Energy and Technology Laboratory of the Department of Energy, Exelis Inc. and AER Inc. The new approach is based on a pair of continuous wave intensity modulated laser absorption spectrometer transceivers, combined with a series of retro reflectors located around the perimeter of the area being monitored. The main goal of this cooperative agreement is monitoring, reporting and verification for ground carbon capture and storage projects. The system was recently tested at the Zero Emission Research and Technology site in Bozeman, MT, with underground leak rates ranging from 0.1 – 0.3 metric ton per day (T/d), as well as a 0.8 T/d surface release. Over 200 hours of data were collected over a rectangular grid 180m x 200m between August 18th and September 9th. In addition, multiple days of in situ data were acquired for the same site, using a Licor gas analyzer systems. Initial comparisons between the laser-based system and the in situ agree very well. The system is designed to operate remotely and transmit the data via a 3G/4G connection along with weather data for the site. An all web-based system ingests the data, populates a database, performs the inversion to ppm CO2 using the Line-by-Line Radiative Transfer Model (LBLRTM), and displays plots and statistics for the retrieved data. We will present an overview of the GreenLITE measurement system, outline the retrieval and reconstruction approach, and discuss results from extensive field testing.

    2008-01-01

    The medical imaging community uses the DICOM image format and protocol to store and exchange data. The Medical Data Manager (MDM) is an interface between DICOM compliant systems such as PACS and the EGEE Data Management System. It opens hospital imaging networks to the world scale Grid while protecting sensitive medical data. It can be accessed transparently from any gLite service. It is an important milestone towards adoption of Grid technologies in the medical imaging community. Hospitals continuously produce tremendous amounts of image data that is managed by local PACS (Picture Archiving and Communication Systems). These systems are often limited to a local network access although the community experiences a growing interest for data sharing and remote processing. Indeed, patient data is often spread out different medical data acquisition centers. Furthermore, researchers in the area often need to analyze large populations whose data can be gathered through federations of PACS. Opening PACS to the outer I...

    1988-01-01

    A study was conducted to identify on-orbit integrated facility needs to support in-space technology experiments on the Space Station and associated free flyers. In particular, the first task was to examine the proposed technology development missions (TDMX's) from the model mission set and other proposed experimental facilities, both individually and by theme, to determine how and if the experiments might be combined, what equipment might be shared, what equipment might be used as generic equipment for continued experimentation, and what experiments will conflict with the conduct of other experiments or Space Station operations. Then using these results, to determine on-orbit facility needs to optimize the implementation of technology payloads. Finally, to develop one or more scenarios, design concepts, and outfitting requirements for implementation of onboard technology experiments.

  20. Study of atmospheric parameters measurements using MM-wave radar in synergy with LITE-2

    Science.gov (United States)

    Andrawis, Madeleine Y.

    1994-01-01

    The Lidar In-Space Technology Experiment, (LITE), has been developed, designed, and built by NASA Langley Research Center, to be flown on the space shuttle 'Discovery' on September 9, 1994. Lidar, which stands for light detecting and ranging, is a radar system that uses short pulses of laser light instead of radio waves in the case of the common radar. This space-based lidar offers atmospheric measurements of stratospheric and tropospheric aerosols, the planetary boundary layer, cloud top heights, and atmospheric temperature and density in the 10-40 km altitude range. A study is being done on the use, advantages, and limitations of a millimeterwave radar to be utilized in synergy with the Lidar system, for the LITE-2 experiment to be flown on a future space shuttle mission. The lower atmospheric attenuation, compared to infrared and optical frequencies, permits the millimeter-wave signals to penetrate through the clouds and measure multi-layered clouds, cloud thickness, and cloud-base height. These measurements would provide a useful input to radiation computations used in the operational numerical weather prediction models, and for forecasting. High power levels, optimum modulation, data processing, and high antenna gain are used to increase the operating range, while space environment, radar tradeoffs, and power availability are considered. Preliminary, numerical calculations are made, using the specifications of an experimental system constructed at Georgia Tech. The noncoherent 94 GHz millimeter-wave radar system has a pulsed output with peak value of 1 kW. The backscatter cross section of the particles to be measured, that are present in the volume covered by the beam footprint, is also studied.

    We evaluate the impact of technology adoption subsidies on investment behavior in an individual choice experiment. In a laboratory setting professional managers are confronted with an intertemporal decision problem in which they have to decide whether or not to search for, and possibly adopt, a new technology. Technologies differ in the per-period benefits they yield, and their purchase price increases with the per-period benefits provided. We introduce a subsidy on the more expensive technologies (that also yield larger per-period benefits), and find that the subsidy scheme induces agents to search for and adopt these more expensive technologies even though the subsidy itself is too small to render these technologies profitable. We speculate that the result is driven by the positive connotation (affect) that the concept 'subsidy' invokes. (author)

    Of all technologies, nuclear technology is perhaps the most interdisciplinary in character as it encompasses such varied fields as nuclear physics, reactor physics, mechanical, electrical electronics controls, metallurgical and even civil and geological engineering. When we speak of transfer of acquisition of nuclear technology we imply cumulative know-how in many fields, most of which are not nuclear per se but are essential for building the necessry infrastructure and back-up facilities for developing and implementing any nuclear energy program. In Pakistan, efforts on utilization of nuclear energy for peaceful applications were initiated about twenty years ago. During these years stepwise development of nuclear technology has taken place. The experience gained by Pakistan so far in transfer of nuclear technology is discussed. Suggestions have been made for continuing the transfer of this most essential technology from the advanced to the developing countries while making sure that necessary safeguard requirements are fullfilled

    The Advanced Communication Technology Satellite (ACTS) is a key to reaching NASA's goal of developing high-risk, advanced communications technology using multiple frequency bands to support the nation's future communication needs. Using the multiple, dynamic hopping spot beams, and advanced on board switching and processing systems, ACTS will open a new era in communications satellite technology. One of the key technologies to be validated as part of the ACTS program is the multibeam antenna with rapidly reconfigurable hopping and fixed spot beam to serve users equipped with small-aperature terminals within the coverage areas. The proposed antenna technology experiments are designed to evaluate in-orbit ACTS multibeam antenna performance (radiation pattern, gain, cross pol levels, etc.).

  7. Technologies of democracy: experiments and demonstrations.

    Science.gov (United States)

    Laurent, Brice

    2011-12-01

    Technologies of democracy are instruments based on material apparatus, social practices and expert knowledge that organize the participation of various publics in the definition and treatment of public problems. Using three examples related to the engagement of publics in nanotechnology in France (a citizen conference, a series of public meetings, and an industrial design process), the paper argues that Science and Technology Studies provide useful tools and methods for the analysis of technologies of democracy. Operations of experiments and public demonstrations can be described, as well as controversies about technologies of democracy giving rise to counter-experiments and counter-demonstrations. The political value of the analysis of public engagement lies in the description of processes of stabilization of democratic orders and in the display of potential alternative political arrangements.

  8. Canadian Experience in Nuclear Power Technology Transfer

    International Nuclear Information System (INIS)

    Boulton, J.

    1987-01-01

    Technology transfer has and will continue to play a major role in the development of nuclear power programs. From the early beginnings of the development of the peaceful uses of nuclear power by just a few nations in the mid-1940s there has been a considerable transfer of technology and today 34 countries have nuclear programs in various stages of development. Indeed, some of the major nuclear vendors achieves their present position through a process of technology transfer and subsequent development. Canada, one of the early leaders in the development of nuclear power, has experience with a wide range of programs bout within its own borders and with other countries. This paper briefly describes this experience and the lessons learned from Canada's involvement in the transfer of nuclear power technology. Nuclear technology is complex and diverse and yet it can be assimilated by a nation given a fire commitment of both suppliers and recipients of technology to achieve success. Canada has reaped large benefits from its nuclear program and we believe this has been instrumentally linked to the sharing of goals and opportunity for participation over extended periods of time by many interests within the Canadian infrastructure. While Canada has accumulated considerable expertise in nuclear technology transfer, we believe there is still much for US to learn. Achieving proficiency in any of the many kinds of nuclear related technologies will place a heavy burden on the financial and human resources of a nation. Care must be taken to plan carefully the total criteria which will assure national benefits in industrial and economic development. Above all, effective transfer of nuclear technology requires a long term commitment by both parties

    The CMS experiment at LHC started using the Resource Broker (by the EDG and LCG projects) to submit Monte Carlo production and analysis jobs to distributed computing resources of the WLCG infrastructure over 6 years ago. Since 2006 the gLite Workload Management System (WMS) and Logging \\& Bookkeeping (LB) are used. The interaction with the gLite-WMS/LB happens through the CMS production and analysis frameworks, respectively ProdAgent and CRAB, through a common component, BOSSLite. The important improvements recently made in the gLite-WMS/LB as well as in the CMS tools and the intrinsic independence of different WMS/LB instances allow CMS to reach the stability and scalability needed for LHC operations. In particular the use of a multi-threaded approach in BOSSLite allowed to increase the scalability of the systems significantly. In this work we present the operational set up of CMS production and analysis based on the gLite-WMS and the performances obtained in the past data challenges and in the daily Mon...

  10. The plasma focus - numerical experiments leading technology

    International Nuclear Information System (INIS)

    Saw, S.H.; Lee, S.

    2013-01-01

    Numerical experiments on the plasma focus are now used routinely to assist design and provide reference points for diagnostics. More importantly guidance has been given regarding the implementation of technology for new generations of plasma focus devices. For example intensive series of experiments have shown that it is of no use to reduce static bank inductance L0 below certain values because of the consistent loading effects of the plasma focus dynamics on the capacitor bank. Thus whilst it was thought that the PF1000 could receive major benefits by reducing its bank inductance L 0 , numerical experiments have shown to the contrary that its present L 0 of 30 nH is already optimum and that reducing L 0 would be a very expensive fruitless exercise. This knowledge gained from numerical experiments now acts as a general valuable guideline to all high performance (ie low inductance) plasma focus devices not to unnecessarily attempt to further lower the static inductance L 0 . The numerical experiments also show that the deterioration of the yield scaling law (e.g. the fusion neutron yield scaling with storage energy) is inevitable again due to the consistent loading effect of the plasma focus, which becomes more and more dominant as capacitor bank impedance reduces with increasing capacitance C 0 as storage energy is increased. This line of thinking has led to the suggestion of using higher voltages (as an alternative to increasing C 0 ) and to seeding of Deuterium with noble gases in order to enhance compression through thermodynamic mechanisms and through radiation cooling effects of strong line radiation. Circuit manipulation e.g. to enhance focus pinch compression by current-stepping is also being numerically experimented upon. Ultimately however systems have to be built, guided by numerical experiments, so that the predicted technology may be proven and realized. (author)

    Spacecraft electric propulsion technology is reviewed here to provide mission planners and potential users with a better appreciation of its capabilities and limitations. Flight experience provides the best measure of EP technology readiness. We describe and document the flight history and development status of EP in domestic, foreign, and commercial programs. Low-power resistojets, arcjets, ion engines, and plasma thrusters are applicable today for stationkeeping and drag compensation. Future high-power systems would enable large velocity-change maneuvers. The trade-space of EP encompasses significant performance benefits (reduced propellant mass, enhanced payload, system-level synergism), along with challenges (hardware development, system operations, non-technical issues). The choice of design parameters (thrust, specific impulse, input power) depends on how much of a change from traditional spacecraft operations is acceptable for a given mission - greater change will yield a greater payoff.

    Full Text Available Information and communication technology (ICT is a prime modality of ordering in the contemporary world. However, order creates and needs its own disorder, and ICT has a long record of failing to deliver on its promises and creating the experience of disorder. This paper looks at the myths of ordering around ICT and then looks at people's experiences of ICT disorder. In particular it looks at three factors: the informal networks that develop because of problems with ICT and with ICT help; the failure of management and communication in hierarchy and finally the failure of requirements engineering to live up to its promise. This focus on disorder may suggest a new way of approaching the so-called ‘Information Society’.

    In Korea, since 1978, the commercial nuclear power plant was operated. After 10 years, from 1988, the nuclear fuel was produced by KNF (Korea Nuclear Fuel). The Fuel Service Team was established at KNF in 1995. Through the technical self reliance periods in cooperate with advanced foreign companies for 5 years, KNF has started to carry out fuel service activities onsite in domestic nuclear power plants. By ceaseless improving and advancing our own methodologies, after that, KNF is able to provide the most safe and reliable fuel repair services and poolside examinations including the root cause analysis of failed fuels. Recently, KNF developed the fuel cleaning system using ultrasonic technique for crud removal, and the CANDU fuel sipping system to detect a failed fuel bundle in PHWR. In this paper, all of KNF's fuel service technologies are briefly described, and the gained experience in shown

    Satyanarayan, Arvind; Moritz, Dominik; Wongsuphasawat, Kanit; Heer, Jeffrey

    2017-01-01

    We present Vega-Lite, a high-level grammar that enables rapid specification of interactive data visualizations. Vega-Lite combines a traditional grammar of graphics, providing visual encoding rules and a composition algebra for layered and multi-view displays, with a novel grammar of interaction. Users specify interactive semantics by composing selections. In Vega-Lite, a selection is an abstraction that defines input event processing, points of interest, and a predicate function for inclusion testing. Selections parameterize visual encodings by serving as input data, defining scale extents, or by driving conditional logic. The Vega-Lite compiler automatically synthesizes requisite data flow and event handling logic, which users can override for further customization. In contrast to existing reactive specifications, Vega-Lite selections decompose an interaction design into concise, enumerable semantic units. We evaluate Vega-Lite through a range of examples, demonstrating succinct specification of both customized interaction methods and common techniques such as panning, zooming, and linked selection.

  20. Reliability and Accuracy of Batak Lite Tests Used for Assessing Coordination Motor Abilities in Wrestlers

    2014-07-01

    Full Text Available Introduction. The aim of this work was to assess selected validity criteria of motor tasks included in Batak Lite. The tasks are used to control coordination motor abilities in athletes of different sports. Material and methods. Twenty male Greco-Roman wrestlers from the sports school SMS in Radom were included in the study. They were 17-18 years of age and their training experience was 4-7.5 years long. The validity of motor tasks was determined on the basis of two criteria, i.e. reliability and diagnostic accuracy. To define the reliability of the tests, the research was carried out twice with an interval of 5-7-days (test-retest. Diagnostic accuracy of selected indices was determined with the help of three main criteria. The analysis included 6 motor tasks performed with the use of Batak Lite. Results. Tests I, II, IV and V are characterised by reliability coefficients higher than 0.50 and, regardless of the assumed accuracy criterion, by coefficients higher than 0.30. Thus, they meet the validity requirements within the assessed criteria. The highest accuracy coefficients were observed in motor tests assessing quick reaction (r = 0.46-0.63, simple reaction including sensory (r = 0.61-0.78, motor (r = 0.33-0.46 and complex (r = 0.34-0.49 reactions as well as spatio-temporal orientation (r = 0.33-0.49 and movement coupling (r = 0.34-0.49. Conclusions. Four Batak Lite tests displayed sufficient reliability and diagnostic accuracy. Therefore, they can be implemented in the training process of wrestlers. The strongest correlation was noted between Batak Lite tests and motor tests that assessed quick reaction, spatio-temporal orientation and movement coupling.

    I will introduce and describe Aladin Lite1, a lightweight interactive sky viewer running natively in the browser. The past five years have seen the emergence of powerful and complex web applications, thanks to major improvements in JavaScript engines and the advent of HTML5. At the same time, browser plugins Java applets, Flash, Silverlight) that were commonly used to run rich Internet applications are declining and are not well suited for mobile devices. The Aladin team took this opportunity to develop Aladin Lite, a lightweight version of Aladin geared towards simple visualization of a sky region. Relying on the widely supported HTML5 canvas element, it provides an intuitive user interface running on desktops and tablets. This first version allows one to interactively visualize multi-resolution HEALPix image and superimpose tabular data and footprints. Aladin Lite is easily embeddable on any web page and may be of interest for data providers which will be able to use it as an interactive previewer for their own image surveys, previously pre-processed as explained in details in the poster "Create & publish your Hierarchical Progressive Survey". I will present the main features of Aladin Lite as well as the JavaScript API which gives the building blocks to create rich interactions between a web page and Aladin Lite.

  5. Implementation of MP_Lite for the VI Architecture

    2001-01-01

    MP_Lite is a light weight message-passing library designed to deliver the maximum performance to applications in a portable and user friendly manner. The Virtual Interface (VI) architecture is a user-level communication protocol that bypasses the operating system to provide much better performance than traditional network architectures. By combining the high efficiency of MP_Lite and high performance of the VI architecture, they are able to implement a high performance message-passing library that has much lower latency and better throughput. The design and implementation of MP_Lite for M-VIA, which is a modular implementation of the VI architecture on Linux, is discussed in this thesis. By using the eager protocol for sending short messages, MP_Lite M-VIA has much lower latency on both Fast Ethernet and Gigabit Ethernet. The handshake protocol and RDMA mechanism provides double the throughput that MPICH can deliver for long messages. MP_Lite M-VIA also has the ability to channel-bonding multiple network interface cards to increase the potential bandwidth between nodes. Using multiple Fast Ethernet cards can double or even triple the maximum throughput without increasing the cost of a PC cluster greatly.

    This paper describes the outstanding performance of the indigenous development program of nuclear power technology such as the design and fabrication of both CANDU and PWR fuel and in the design and construction of nuclear steam supply system in Korea. The success has been accomplished through the successful technology transfer from foreign suppliers and efficient utilization of R and D manpower in the design and engineering of nuclear power projects. In order to implement the technology transfer successfully, the joint design concept has been introduced along with effective on-the-job training and the transfer of design documents and computer codes. Korea's successful development of nuclear power program has resulted in rapid expansion of nuclear power generation capacity in a short time, and the nuclear power has contributed to the national economy through lowering electricity price by about 50 % as well as stabilizing electricity supply in 1980s. The nuclear power is expected to play a key role in the future electricity supply in Korea. Now Korea is under way of taking a step toward advanced nuclear technology. The national electricity system expansion plan includes 18 more units of NPPs to be constructed by the year 2006. In this circumstance, the country has fixed the national long-term nuclear R and D program (lgg2-2001) to enhance the national capability of nuclear technology. This paper also briefly describes future prospects of nuclear technology development program in Korea

    This study examined the relations of preservice science teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences to their self-efficacy beliefs about technological pedagogical content knowledge (TPACK). The present study also investigated interrelations among preservice teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences. The participants of study were 665 elementary preservice science teachers (467 females, 198 males) from 7 colleges in Turkey. The proposed model based on educational technology literature was tested using structural equation modeling. The model testing results revealed that preservice teachers' technology competencies and experiences mediated the relation of technology ownership to their TPACK self efficacy beliefs. The direct relation of their possession of technology to their TPACK self efficacy beliefs was insignificant while the indirect relation through their technology competencies and experiences was significant. The results also indicated there were significant direct effects of preservice teachers' attitudes towards technology use, technology competencies, and experiences on their TPACK self efficacy beliefs.

  13. How medical technologies shape the experience of illness.

    Hofmann, Bjørn; Svenaeus, Fredrik

    2018-02-03

    In this article we explore how diagnostic and therapeutic technologies shape the lived experiences of illness for patients. By analysing a wide range of examples, we identify six ways that technology can (trans)form the experience of illness (and health). First, technology may create awareness of disease by revealing asymptomatic signs or markers (imaging techniques, blood tests). Second, the technology can reveal risk factors for developing diseases (e.g., high blood pressure or genetic tests that reveal risks of falling ill in the future). Third, the technology can affect and change an already present illness experience (e.g., the way blood sugar measurement affects the perceived symptoms of diabetes). Fourth, therapeutic technologies may redefine our experiences of a certain condition as diseased rather than unfortunate (e.g. assisted reproductive technologies or symptom based diagnoses in psychiatry). Fifth, technology influences illness experiences through altering social-cultural norms and values regarding various diagnoses. Sixth, technology influences and changes our experiences of being healthy in contrast and relation to being diseased and ill. This typology of how technology forms illness and related conditions calls for reflection regarding the phenomenology of technology and health. How are medical technologies and their outcomes perceived and understood by patients? The phenomenological way of approaching illness as a lived, bodily being-in-the-world is an important approach for better understanding and evaluating the effects that medical technologies may have on our health, not only in defining, diagnosing, or treating diseases, but also in making us feel more vulnerable and less healthy in different regards.

    The large helical device (LHD), which is the world largest helical confinement system, is a national project serving Japanese fusion community. In LHD, experiments of 7000 shots are carried out for 250 proposals every year. Efficient experiment arrangement is required in order to carry out many collaborators' proposal. Sometimes collaborators who are not familiar to LHD stay at NIFS only a few day to join the experiment. Issues are as follows: how to reduce collaborator's effort, how to reduce manager's effort to optimize the schedule; how to publicize plan and results of the experiment. We have developed web systems of virtual printer, experimental proposal and scheduling by using Ruby on Rails (RoR), which encapsulates relational data base (RDB) and AJAX. RDB enables to make tables by searching and sorting data with key words. Web servers are equipped in the virtual computer system in order to minimize efforts and cost of maintenance. The LHD web portal has been also developed in order to provide collaborators an efficient and intuitive interface to access the above systems, to take LHD information, and to use tools for LHD data analysis. The web systems have reduced collaborators' and managers' efforts significantly.

    Belgium pioneered in non energetic applications of nuclear science. In 1970, the National Institute for Radioisotopes (IRE) was founded on the ground of the experience acquired at the CEN/SCK, for developing nuclear techniques oriented to the well-being of population. In 1978 IRE started operation of 2 γ-irradiation units with a 2.25 million Ci Co 60 , source having a capacity for sterilization of more than 100 m 3 of product per day. this installation is currently operated by Griffith-Mediris (Group Griffith Micro Science) and has accumulated 20 years of experience for irradiation of foodstuffs, medical appliances and pharmaceuticals. In 1986, IRE was producing radioisotopes from accelerators and joined UCL for founding Ion Beam Applications (IBA) company which shortly became the world leader for design and delivery of cyclotrons. More recently, on the basis of French CEA patent, IBA developed the Rhodotron, an e-beam accelerator, with an X-ray option, which is now facing commercial success i area of ionization of food and medical appliances. IRE developed also expertise for the back-end of these activities i.e. final disposal of radioactive sealed source and dismantling of the installations. (author)

    The infusion of health care technologies into the home leads to substantial changes in the nature of work for home care nurses and their patients. Nurses and nursing practice must change to capitalize on these innovations. As part of a randomized field experiment evaluating web-based support for home care of patients with chronic heart disease, we engaged nine nurses in a dialogue about their experience integrating this modification of care delivery into their practice. They shared their perceptions of the work they needed to do and their perceptions and expectations for patients and themselves in using technologies to promote and manage self-care. We document three overarching themes that identify preexisting factors that influenced integration or represent the consequences of technology integration into home care: doing tasks differently, making accommodations in the home for devices and computers, and being mindful of existing expectations and skills of both nurses and patients.

    The COLD-SAT spacecraft will perform subcritical liquid hydrogen storage and transfer experiments under low-gravity conditions to provide engineering data for future space transportation missions. Consisting of an experiment module mated to a spacecraft bus, COLD-SAT will be placed in an initial 460 km circular orbit by an Atlas I commercial launch vehicle. After deployment, the three-axis-controlled spacecraft bus will provide electric power, experiment control and data management, communications, and attitude control along with propulsive acceleration levels ranging from 10 (-6) to 10(-4) g. These accelerations are an important aspect of some of the experiments, as it is desired to know the effects that low gravity levels might have on the heat and mass transfer processes involved. The experiment module will contain the three liquid hydrogen tanks, valves, pressurization equipment, and instrumentation. At launch all the hydrogen will be in the largest tank, which has helium-purged MLI and is loaded and topped off by the hydrogen tanking system used for the Centaur upper stage of the Atlas. The two smaller tanks will be utilized in orbit for performing some of the experiments. The experiments are grouped into two classes on the basis of their priority, and include six regarded as enabling technology and nine regarded as enhancing technology.

    2002-07-01

    The NASA Integrated Vehicle Health Management (IVHM) Technology Experiment for X-37 was intended to run IVHM software on board the X-37 spacecraft. The X-37 is an unpiloted vehicle designed to orbit the Earth for up to 21 days before landing on a runway. The objectives of the experiment were to demonstrate the benefits of in-flight IVHM to the operation of a Reusable Launch Vehicle, to advance the Technology Readiness Level of this IVHM technology within a flight environment, and to demonstrate that the IVHM software could operate on the Vehicle Management Computer. The scope of the experiment was to perform real-time fault detection and isolation for X-37's electrical power system and electro-mechanical actuators. The experiment used Livingstone, a software system that performs diagnosis using a qualitative, model-based reasoning approach that searches system-wide interactions to detect and isolate failures. Two of the challenges we faced were to make this research software more efficient so that it would fit within the limited computational resources that were available to us on the X-37 spacecraft, and to modify it so that it satisfied the X-37's software safety requirements. Although the experiment is currently unfunded, the development effort resulted in major improvements in Livingstone's efficiency and safety. This paper reviews some of the details of the modeling and integration efforts, and some of the lessons that were learned.

    With a focus on gaining an empirically derived understanding of the underlying psychological dimensions and processes behind people’s experiences with technology, this book contributes to the debate of user experience (UX) within several disciplines, including HCI, design and marketing. It analyses UX dynamics at various time scales, and explores the very nature of time and meaning in the context of UX.Experience with Technology uses personal construct theory (PCT) as a theoretical and methodological starting point to this project. Major case-studies are described that examine people’s exp

    Vehicle-based crash avoidance systems can potentially reduce crashes, but success depends on driver acceptance and understanding. This study gauged driver use, experience, and acceptance among early adopters of select technologies. Telephone interviews were conducted in early 2009 with 380 owners of Volvo vehicles equipped with forward collision warning with autobrake, lane departure warning, side-view assist, and/or active bi-xenon headlights and 485 owners of Infiniti vehicles with lane departure warning/prevention. Most owners kept systems turned on most of the time, especially forward collision warning with autobrake and side-view assist. The exception was lane departure prevention; many owners were unaware they had it, and the system must be activated each time the vehicle is started. Most owners reported being safer with the technologies and would want them again on their next vehicles. Perceived false or unnecessary warnings were fairly common, particularly with side-view assist. Some systems were annoying, especially lane departure warning. Many owners reported safer driving behaviors such as greater use of turn signals (lane departure warning), increased following distance (forward collision warning), and checking side mirrors more frequently (side-view assist), but some reported driving faster at night (active headlights). Despite some unnecessary or annoying warnings, most Volvo and Infiniti owners use crash avoidance systems most of the time. Among early adopters, the first requirement of effective warning systems (that owners use the technology) seems largely met. Systems requiring activation by drivers for each trip are used less often. Owner experience with the latest technologies from other automobile manufacturers should be studied, as well as for vehicles on which technologies are standard (versus optional) equipment. The effectiveness of technologies in preventing and mitigating crashes and injuries, and user acceptance of interfaces, should be

    LiteBIRD [Lite (Light) satellite for the studies of B-mode polarization and Inflation from cosmic background Radiation Detection] is a small satellite to map the polarization of the cosmic microwave background (CMB) radiation over the full sky at large angular scales with unprecedented precision. Cosmological inflation, which is the leading hypothesis to resolve the problems in the Big Bang theory, predicts that primordial gravitational waves were created during the inflationary era. Measurements of polarization of the CMB radiation are known as the best probe to detect the primordial gravitational waves. The LiteBIRD working group is authorized by the Japanese Steering Committee for Space Science (SCSS) and is supported by JAXA. It has more than 50 members from Japan, USA and Canada. The scientific objective of LiteBIRD is to test all the representative inflation models that satisfy single-field slow-roll conditions and lie in the large-field regime. To this end, the requirement on the precision of the tensor-to-scalar ratio, r, at LiteBIRD is equal to or less than 0.001. Our baseline design adopts an array of multi-chroic superconducting polarimeters that are read out with high multiplexing factors in the frequency domain for a compact focal plane. The required sensitivity of 1.8μKarcmin is achieved with 2000 TES bolometers at 100mK. The cryogenic system is based on the Stirling/JT technology developed for SPICA, and the continuous ADR system shares the design with future X-ray satellites.

  9. Transforming Inclusion: Designing in the Experience of Greater Technological Possibility.

    Universal Design seeks to contribute to the sustainability and inclusivity of communities and co-design and participatory methods are a critical tool in this evolution. The fact that technology permeates our society is undeniable and the form and materials that technology takes in turn shape the basics of human life such as being able to shower and toilet oneself. In contrast, the various existing approaches to co-design have very different sorts of metaphysical, epistemological and normative assumptions behind them. As a result, design has recognised a set of problems surrounding the position of the "user" in design innovation. Additionally, there are many different perspectives on technology and the role of technology in co-design methods. Consequently, there are a number of different ways of conceiving of the "problem" of integrating technologies into co-design methods. Traditionally, participatory design has been viewed as merely the insertion of a more public dialog of the potential target market within technological design practices. Our research indicates that most if not all co-designers rely on their own personal and collective knowledge and experience and that if this is not actively explored as a part of a co-design methodology that both participation and innovation will be less than hoped for. For instance, assuming only known fixtures, fittings with current codes and standards is unlikely to result in product innovation.

    1978-01-01

    A heavy ion beam probe plasma diagnostic system has been developed for the Laser Initiated Target Experiment (LITE) at UTRC. This is the first application of ion beam probing to a plasma confined by a strongly three dimensional magnetic field. The deep magnetic well, minimum-B field produced by the ''baseball'' magnet coil results in complex trajectories and severe defocusing of both the injected primary beam and detected secondary beam. Spatial resolution can be maintained by aperturing the entrance slit to the detector or installing compensating ion optics. The system is capable of space and time resolved measurements of plastic density and space potential near the central region of the mirror-confined plasma. 11 refs

    The technical issues and requirements of experiments and facilities for fusion nuclear technology (FNT) have been investigated. The nuclear subsystems addressed are: a) blanket, b) radiation shield, c) tritium processing system, and d) plasma interactive components. Emphasis has been placed on the important and complex development problems of the blanket. A technical planning process for FNT has been developed and applied, including four major elements: 1) characterization of issues, 2) quantification of testing requirements, 3) evaluation of facilities, and 4) development of a test plan to identify the role, timing, characteristics and costs of major experiments and facilities

    This paper discusses the development and results of two intelligent structures space-flight experiments, each of which could affect architecture designs of future spacecraft. The first, the advanced controls technology experiment I (ACTEX I), is a variable stiffness tripod structure riding as a secondary payload on a classified spacecraft. It has been operating well past its expected life since becoming operational in 1996. Over 60 on-orbit experiments have been run on the ACTEX I flight experiment. These experiments form the basis for in-space controller design problems and for concluding lifetime/reliability data on the active control components. Transfer functions taken during the life of ACTEX I have shown consistent predictability and stability in structural behavior, including consistency with those measurements taken on the ground prior to a three year storage period and the launch event. ACTEX I can change its modal characteristics by employing its dynamic change mechanism that varies preloads in portions of its structure. Active control experiments have demonstrated maximum vibration reductions of 29 dB and 16 dB in the first two variable modes of the system, while operating over a remarkable on-orbit temperature range of -80 °C to 129 °C. The second experiment, ACTEX II, was successfully designed, ground-tested, and integrated on an experimental Department of Defense satellite prior to its loss during a launch vehicle failure in 1995. ACTEX II also had variable modal behavior by virtue of a two-axis gimbal and added challenges of structural flexibility by being a large deployable appendage. Although the loss of ACTEX II did not provide space environment experience, ground testing resulted in space qualifying the hardware and demonstrated 21 dB, 14 dB, and 8 dB reductions in amplitude of the first three primary structural modes. ACTEX II could use either active and/or passive techniques to affect vibration suppression. Both experiments trailblazed

    AUTHOR|(CDS)2088631; The ATLAS collaboration

    2017-01-01

    Because of their performance characteristics high-performance fabrics like Infiniband or OmniPath are interesting technologies for many local area network applications, including data acquisition systems for high-energy physics experiments like the ATLAS experiment at CERN. This paper analyzes existing APIs for high-performance fabrics and evaluates their suitability for data acquisition systems in terms of performance and domain applicability. The study finds that existing software APIs for high-performance interconnects are focused on applications in high-performance computing with specific workloads and are not compatible with the requirements of data acquisition systems. To evaluate the use of high-performance interconnects in data acquisition systems a custom library, NetIO, is presented and compared against existing technologies. NetIO has a message queue-like interface which matches the ATLAS use case better than traditional HPC APIs like MPI. The architecture of NetIO is based on a interchangeable bac...

    Crash avoidance technologies can potentially prevent or mitigate many crashes, but their success depends in part on driver acceptance. Owners of 2010-2012 model Volvo vehicles with several technologies were interviewed about their experiences. Interviews were conducted in summer 2012 with 155 owners of vehicles with City Safety as a standard feature; 145 owners with an optional technology package that included adaptive cruise control, distance alert, collision warning with full auto brake (and pedestrian detection on certain models), driver alert control, and lane departure warning; and 172 owners with both City Safety and the technology package. The survey response rates were 21 percent for owners with City Safety, 30 percent for owners with the technology package, and 27 percent for owners with both. Ten percent of owners opted out before the telephone survey began, and 18 percent declined to participate when called. Despite some annoyance, most respondents always leave the systems on, although fewer do so for lane departure warning (59%). For each of the systems, at least 80 percent of respondents with the system would want it on their next vehicle. Many respondents reported safer driving habits with the systems (e.g., following less closely with adaptive cruise control, using turn signals more often with lane departure warning). Fewer respondents reported potentially unsafe behavior, such as allowing the vehicle to brake for them at least some of the time. About one third of respondents experienced autonomous braking when they believed they were at risk of crashing, and about one fifth of respondents thought it had prevented a crash. About one fifth of respondents with the technology package reported that they were confused or misunderstood which safety system had activated in their vehicle. Consistent with the results for early adopters in the previous survey of Volvo and Infiniti owners, the present survey found that driver acceptance of the technologies

    2007-01-01

    This report examines two important generic photovoltaic technologies at particularly revealing stages of development, i.e., the stages between R&D and stable commercial production and profitable sales. Based on two historical cases, it attempts to shed light on the difference between: (1) costs and schedules validated by actual manufacturing and market experience, and (2) estimated costs and schedules that rely on technology forecasts and engineering estimates. The amorphous Silicon case also identifies some of the costs that are incurred in meeting specific market requirements, while the Cadmium Telluride case identifies many of the operational challenges involved in transferring R&D results to production. The transition between R&D and commercial success takes a great deal of time and money for emerging energy conversion technologies in general. The experience reported here can be instructive to those managing comparable efforts, and to their investors. It can also be instructive to R&D managers responsible for positioning such new technologies for commercial success.

    Numerous studies have demonstrated a relationship between adherence to Mediterranean diet and prevention of chronic degenerative diseases. The aim of this study was to validate a novel instrument to measure adherence to Mediterranean diet based on the literature (the MEDI-LITE score). Two-hundred-and-four clinically healthy subjects completed both the MEDI-LITE score and the validated MedDietScore (MDS). Significant positive correlation between the MEDI-LITE and the MDS scores was found in the study population (R = .70; p MEDI-LITE evidenced a significant discriminative capacity between adherents and non-adherents to the Mediterranean diet pattern (optimal cut-off point = 8.50; sensitivity = 96%; specificity = 38%). In conclusion, our findings show that the MEDI-LITE score well correlate with MDS in both global score and in most of the items related to the specific food categories.

    The Limb-Imaging Ionospheric and Thermospheric Extreme-Ultraviolet Spectrograph (LITES) is an extreme-ultraviolet imaging spectrograph that launched in February 2017 and was installed on the International Space Station (ISS). LITES is limb-viewing ( 150 - 350 km tangent altitude) and measures airglow emissions from 60 - 140 nm with 0.2° angular and 1 nm spectral resolutions. We present early LITES results of observations during a G2 geomagnetic storm in April 2017. In addition to LITES data, we will show complementary ground-based incoherent scatter radar (ISR) observations from Millstone Hill during this storm. The combination of LITES EUV space-based observations with the ground-based radio data is an example of the capability of campaign-style measurements of the ionosphere-thermosphere system using multiwavelength ground- and space-based instruments.

    To describe how virtual patients are being used to simulate real-life clinical scenarios in undergraduate pharmacy education in Europe. One hundred ninety-four participants at the 2011 Congress of the European Pharmaceutical Students Association (EPSA) completed an exploratory cross-sectional survey instrument. Of the 46 universities and 23 countries represented at the EPSA Congress, only 12 students from 6 universities in 6 different countries reported having experience with virtual patient technology. The students were satisfied with the virtual patient technology and considered it more useful as a teaching and learning tool than an assessment tool. Respondents who had not used virtual patient technology expressed support regarding its potential benefits in pharmacy education. French and Dutch students were significantly less interested in virtual patient technology than were their counterparts from other European countries. The limited use of virtual patients in pharmacy education in Europe suggests the need for initiatives to increase the use of virtual patient technology and the benefits of computer-assisted learning in pharmacy education.

  20. Evaluation of technology transferring: The experiences of the first Navy Domestic Technology Transfair. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1989-12-31

    In August 1989 the Office of the Chief of Naval Research and the American Defense Preparedness Association conducted the first Navy Domestic Technology Transfair. The objective of the Transfair was to expose the US Navy`s years of solid experience across a broad span of technology to organizations outside of the Navy. It was an opportunity for private industry to capitalize on the Navy developed technology and this opening for industry was the primary focus of the Transfair. The event provided a unique forum to meet leading Navy scientific and engineering innovators face-to-face. Information was available concerning licensing of naval technology that was for sale to the private sector. Further, discussions covered opportunities for new cooperative research and development agreements with Navy laboratories and R&D activities. These agreements were authorized under the Federal Technology Transfer Act of 1986. The Transfair program was conducted in such a manner as to allow each Navy inventor, either scientist or engineer, to present a system, piece of hardware, or licensable concept in a formal paper presentation. Then, the Navy inventors were available in two, two-hour periods in which individual discussions were conducted, with attendees pursuing specific venues of cooperative agreements as desired. This report provides specifics concerning the technologies that were made available for transfer to the private sector during the Transfair. The Transfair concept sought to add special emphasis to the opening that the 1988 Technology Transfer Act brought to the marketplace. The experience was a step in the education of the possibilities for cooperation between the government and the private sector to share technology. Of additional significance is the economic enhancement for business expansion with the application of the technology to markets beyond defense.

    It is generally assumed that incoming students in medical education programs will be better equipped for the "digital age" given their younger age and an educational upbringing in which technology was seemingly omnipresent. In particular, many assume that today's medical students are more likely to hold positive attitudes and increased comfortability with technology and possess greater information technology (IT) skills. The purpose of this study was to compare responses of incoming veterinary medical students to a series of IT-related questions contained in a common questionnaire over the course of a 10-year period (2005-2015) to discern whether students' attitudes have improved and uses and comfortability with technology have increased as anticipated. A survey measuring attitudes and preferences, computing experience, and technology ownership was administered each year for the past 10 years to incoming veterinary medical students at a large veterinary school in the United States. Students' responses to survey items were compared at 3 data points (2005, 2010, and 2015). Today's incoming veterinary medical students tend to indicate the same desire to improve skills using spreadsheets and web page design as incoming students from 10 years ago. It seems that despite technological advances and increased exposure to such applications and skills, there remains a challenge for students to "keep up" with the ever evolving technology. Moreover, although students continue to report they are very comfortable with using a computer (and related devices), many use their computers as typewriters or word processors, as opposed to a means for performing more advanced computing functions. In general, today's medical students are not expert computer users as many assume. Despite an upbringing in a digitized world, many students still lack many basic computing skills.

    The LiteBIRD satellite aims at detecting a signature imprinted on the cosmic microwave background (CMB) by the primordial gravitational wave predicted in inflation, which is an exponentially expanding era before the hot big bang. The extraction of such weak spiral polarization patterns requires the precise subtraction of our Galaxy's foreground emission such as the synchrotron and the dust emission. In order to separate them from the CMB by using their spectral shape differences, LiteBIRD covers a wide range of observing frequencies. The main telescope, Low Frequency Telescope (LFT), covers the CMB peak frequencies as well as the synchrotron emission. Based on the required sizes of optical elements in the LFT, an order of one meter, the telescope will consist of reflectors rather than lenses since the latter is limited in size availabilities of the corresponding materials. The image quality analysis provides the requirements of reflector surface shape errors within 30um rms. The requirement on surface roughness of 2μm rms is determined from the reflectance requirement. Based on these requirements, we have carried out tradeoff studies on materials used for reflectors and their support structures. One possibility is to athermalize with aluminum, with the expected thermal contract of 0.4% from room temperature to 4-10 K. Another possibility is CFRP with cyanate resin, which is lighter and has negligibly small thermal contraction. For the reflector surface shape measurements including in low temperature, photogrammetry is a strong candidate with suitable accuracy and dynamic range of measurements.

    2015-01-01

    New battery systems having high energy density are actively being researched in order to satisfy the rapidly developing market for longer-lasting mobile electronics and hybrid electric vehicles. Here, we report a new Li-Te secondary battery system with a redox potential of ~1.7 V (vs. Li+/Li) adapted on a Li metal anode and an advanced Te/C nanocomposite cathode. Using a simple concept of transforming TeO2 into nanocrystalline Te by mechanical reduction, we designed an advanced, mechanically reduced Te/C nanocomposite electrode material with high energy density (initial discharge/charge: 1088/740 mA h cm-3), excellent cyclability (ca. 705 mA h cm-3 over 100 cycles), and fast rate capability (ca. 550 mA h cm-3 at 5C rate). The mechanically reduced Te/C nanocomposite electrodes were found to be suitable for use as either the cathode in Li-Te secondary batteries or a high-potential anode in rechargeable Li-ion batteries. We firmly believe that the mechanically reduced Te/C nanocomposite constitutes a breakthrough for the realization and mass production of excellent energy storage systems.

    Over the next three years the research program of the Heavy Ion Fusion Virtual National Laboratory (HIF-VNL), a collaboration among LBNL, LLNL, and PPPL, is focused on separate scientific experiments in the injection, transport and focusing of intense heavy ion beams at currents from 100 mA to 1 A. As a next major step in the HIF-VNL program, we aim for a complete 'source-to-target' experiment, the Integrated Beam Experiment (IBX). By combining the experience gained in the current separate beam experiments IBX would allow the integrated scientific study of the evolution of a single heavy ion beam at high current (∼1 A) through all sections of a possible heavy ion fusion accelerator: the injection, acceleration, compression, and beam focusing.This paper describes the main parameters and technology choices of the planned IBX experiment. IBX will accelerate singly charged potassium or argon ion beams up to 10 MeV final energy and a longitudinal beam compression ratio of 10, resulting in a beam current at target of more than 10 Amperes.

    For more than 10 years the conventional media for High Energy Physics has been 9 track magnetic tape in various densities. More recently, especially in Europe, the IBM 3480 technology has been adopted while in the United States, especially at Fermilab, 8mm is being used by the largest experiments as a primary recording media and where possible they are using 8mm for the production, analysis and distribution of data summary tapes. VHS and Digital Audio tape have recurrently appeared but seem to serve primarily as back-up storage media. The reasons for what appear to be a radical departure are many. Economics, form factor, and convenience are dominant among the reasons. The traditional data media suppliers seem to have been content to evolve the traditional media at their own pace with only modest enhancements primarily in value engineering'' of extant products. Meanwhile, start-up companies providing small system and workstations sought other media both to reduce the price of their offerings and respond to the real need of lower cost back-up for lower cost systems. This happening in a market context where traditional computer systems vendors were leaving the tape market altogether or shifting to 3480'' technology which has certainly created a climate for reconsideration and change. The newest data storage products, in most cases, are not coming from the technologies developed by the computing industry but by the audio and video industry. Just where these flopticals, opticals, 19 mm tape and the new underlying technologies, such as, digital paper'' may fit in the HEP computing requirement picture will be reviewed. What these technologies do for and to HEP will be discussed along with some suggestions for a methodology for tracking and evaluating extant and emerging technologies.

    The development of charged particle bombardment experiments to simulate neutron irradiation induced swelling in austenitic alloys is briefly described. The applications of these techniques in LMFBR core materials technology are discussed. It is shown that use of the techniques to study the behavior of cold-worked Type-316 was instrumental in demonstrating at an early date the need for advanced materials. The simulation techniques then were used to identify alloying elements which can markedly decrease swelling and thus a focused reactor irradiation program is now in place to allow the future use of a lower swelling alloy for LMFBR core components

    Nixdorf, U.

    1993-12-01

    High Energy Physics experiments are known for their production of large amounts of data. Even small projects may have to manage several Giga Byte of event information. One possible solution for the management of this data is to use today's technology to archive the raw data files in tertiary storage and build on-line catalogs which reference interesting data. This approach has been taken by the Gammas, Electrons and Muons (GEM) Collaboration for their evaluation of muon chamber technologies at the Superconducting Super Collider Laboratory (SSCL). Several technologies were installed and tested during a 6 month period. Events produced were first recorded in the UNIX filesystem of the data acquisition system and then migrated to the Physics Detector Simulation Facility (PDSF) for long term storage. The software system makes use of a commercial relational database management system (SYBASE) and the Data Management System (DMS), a tape archival system developed at the SSCL. The components are distributed among several machines inside and outside PDSF. A Motif-based graphical user interface (GUI) enables physicists to retrieve interesting runs from the archive using the on-line database catalog

    Full Text Available The paper will explore how a social media based E-learning 2.0 solution for formal learning (social IS can be implemented, focusing on the technology acceptance process. The paper aims to increase the knowledge on how the acceptance regarding social media based E-learning 2.0 information systems for formal learning can be increased and how the acceptance affects the social learning experience. To achieve this, the paper relies on both a qualitative and quantitative approach and is primarily inductive. The paper concludes that the acceptance cannot be seen as a linear process, as is common practice. Instead, one should see the process of acceptance as interlinked with the experience and external variables in a continuous process that can either ‘spiral’ upwards or downwards. Furthermore, the paper identifies the problem of innovation resistance. The paper then analyzes information gathered from industry experts, practitioners and a live case to find how one can improve acceptance and thereby the social learning experience. Once these variables have been identified the paper presents strategic advice. The paper ends by a discussion of the results, both regarding the impact and contrast to previous research as well as highlighting areas for further research

    The Laser Astrometric Test of Relativity (LATOR) is a Michelson-Morley-type experiment designed to test the Einstein's general theory of relativity in the most intense gravitational environment available in the solar system - the close proximity to the Sun. By using independent time-series of highly accurate measurements of the Shapiro time-delay (laser ranging accurate to 1 cm) and interferometric astrometry (accurate to 0.1 picoradian), LATOR will measure gravitational deflection of light by the solar gravity with accuracy of 1 part in a billion, a factor {30,000 better than currently available. LATOR will perform series of highly-accurate tests of gravitation and cosmology in its search for cosmological remnants of scalar field in the solar system. We present science, technology and mission design for the LATOR mission.

    The aim of the Technical Workshop on safeguards was to encourage a clearer understanding of the IAEA Safeguards System, its origins and evolution and the present state of the art. Presentations held by the IAEA officials and outside experts examined as well other components of the non-proliferation regime, the current practices and procedures, and the future prospects. A series of presentations described the characteristics of the interaction between global and regional verification systems and described relevant past and present experience. Prominence given to such state of the art verification technologies as environmental sampling, satellite imaging and monitoring thorough remote and unattended techniques demonstrated, beyond any doubt, the essentially dynamic nature of verification. It is generally acknowledged that there have been major achievements in preventing spread of nuclear weapons, but no verification system can in itself prevent proliferation

  1. Magnetic confinement of laser produced LiH plasma in LITE

    International Nuclear Information System (INIS)

    Ard, W.B.; Stufflebeam, J.H.; Tomlinson, R.G.

    1976-01-01

    In the LITE experiment, a hot, dense plasma produced by laser heating of an approximately 100 μ dia LiH particle is used to fill a minimum-B baseball coil mirror magnetic containment field. The confined laser produced plasma subsequently serves as the target for an energetic neutral hydrogen beam in experiments to investigate the target plasma buildup approach for creating and sustaining an equilibrium, steady state mirror fusion plasma. In the experiments, the LiH particle is positioned in vacuum at the laser beam focus by a feedback particle suspension system and heated by two sided irradiation with the focused dual beam, 50 j, 7 nsec output of a Q-switched Nd-glass laser. The energy density of the laser produced plasma is initially much greater than that of the surrounding magnetic field and the plasma expands, converting its internal energy into expansion kinetic energy and displacement of the magnetic field. As the energy density falls below that of the magnetic field, the expansion is stopped and the plasma becomes trapped, making the transition to a low beta, mirror confined plasma. This report is concerned with the properties and behavior of the plasma in the confinement stage

    Hospital Based Health Technology Assessment (HBHTA) practices, to inform decision making at the hospital level, emerged as urgent priority for policy makers, hospital managers, and professionals. The present study crystallized the results achieved by the testing of an original framework for HBHTA, developed within Lombardy Region: the IMPlementation of A Quick hospital-based HTA (IMPAQHTA). The study tested: (i) the HBHTA framework efficiency, (ii) feasibility, (iii) the tool utility and completeness, considering dimensions and sub-dimensions. The IMPAQHTA framework deployed the Regional HTA program, activated in 2008 in Lombardy, at the hospital level. The relevance and feasibility of the framework were tested over a 3-year period through a large-scale empirical experiment, involving seventy-four healthcare professionals organized in different HBHTA teams for assessing thirty-two different technologies within twenty-two different hospitals. Semi-structured interviews and self-reported questionnaires were used to collect data regarding the relevance and feasibility of the IMPAQHTA framework. The proposed HBHTA framework proved to be suitable for application at the hospital level, in the Italian context, permitting a quick assessment (11 working days) and providing hospital decision makers with relevant and quantitative information. Performances in terms of feasibility, utility, completeness, and easiness proved to be satisfactory. The IMPAQHTA was considered to be a complete and feasible HBHTA framework, as well as being replicable to different technologies within any hospital settings, thus demonstrating the capability of a hospital to develop a complete HTA, if supported by adequate and well defined tools and quantitative metrics.

  3. Experience with civil plutonium management: Technology and economics

    1997-01-01

    Recent NEA work on plutonium has been, essentially, targeted at economic and scientific aspects and the need to identify suitable technical solutions, despite the existing political uncertainties associated with their implementation. Such studies provide the facts and current views concerning plutonium and its civil use; address questions influencing the choice of fuel cycle options and illustrate how economic and logistic assessments of the alternatives could be undertaken. An ad-hoc expert group, with a membership drawn from fifteen countries and three international organisations, which was formed in early 1994 under the auspices of the NEA, with the task of identifying, examining and evaluating the broad technical questions related to plutonium management, has just published its work. This paper discusses the work and main conclusions of the expert group and focuses on the following two topics: Technologies, already implemented, which provide for short and medium-term storage of plutonium or for recycling the plutonium through reactors. A brief review is provided of experience gained with them and technical commentaries are made on their potential future deployment; Such technologies may, in the longer term, be joined by a further range which are, in some cases, already under development. Attention is drawn to those additional options that may become available. Another NEA expert group studied in detail the economics of the open and closed fuel cycles and reported, in 1994, its main findings: Some economic considerations of importance to various aspects of plutonium recycling are also presented in this paper.

    Increasing awareness on environmental damage and climate change has induced many nations to engage in green growth. South Korea, as one of the largest consumers of energy, is no exception and has shown its determination to pursue green growth in the future. In order to do so, South Korea plans to substitute fossil fuel with alternative sources in electricity generation. However, the key constraint to green growth is the high cost faced by renewable electricity generation. Fortunately, nuclear energy can serve as an economic alternative to fossil fuel. To achieve CO 2 emission reduction and faster economic growth, it is wise to analyze prospects of alternatives using experience curve framework. The results and industry background are consistent for nuclear technology, and the results suggest that nuclear should serve as the main substitute. Consideration of policy risk inherent in renewable also strengthens the argument. Renewable technologies, on the other hand, showed overstated learning capacity that is partially inconsistent with technological background. Nevertheless, the renewable (photovoltaic and fuel cell) should help nuclear marginally in substituting fossil fuel in South Korea's Electricity Generation. - Highlights: ► Progress ratios of renewable energy show great prospect. ► The policy risk is inherent in renewable and may overestimate its prospect. ► Nuclear sources are economic and less affected by policy risk. ► Fuel cell and photovoltaic should help nuclear marginally in green growth.

  6. AECL experience with low-level radioactive waste technologies

    Buckley, L.P.; Charlesworth, D.H.

    1988-08-01

    Atomic Energy of Canada Limited (AECL), as the Canadian government agency responsible for research and development of peaceful uses of nuclear energy, has had experience in handling a wide variety of radioactive wastes for over 40 years. Low-level radioactive waste (LLRW) is generated in Canada from nuclear fuel manufacturers and nuclear power facilities, from medical and industrial uses of radioisotopes and from research facilities. The technologies with which AECL has strength lie in the areas of processing, storage, disposal and safety assessment of LLRW. While compaction and incineration are the predominant methods practised for solid wastes, purification techniques and volume reduction methods are used for liquid wastes. The methods for processing continue to be developed to improve and increase the efficiency of operation and to accommodate the transition from storage of the waste to disposal. Site-specific studies and planning for a LLRW disposal repository to replace current storage facilities are well underway with in-service operation to begin in 1991. The waste will be disposed of in an intrusion-resistant underground structure designed to have a service life of over 500 years. Beyond this period of time the radioactivity in the waste will have decayed to innocuous levels. Safety assessments of LLRW disposal are performed with the aid of a series of interconnected mathematical models developed at Chalk River specifically to predict the movement of radionuclides through and away from the repository after its closure and the subsequent health effects of the released radionuclides on the public. The various technologies for dealing with radioactive wastes from their creation to disposal will be discussed. 14 refs

    Kolotkin, Ronette L; Crosby, Ross D

    2002-03-01

    The short form of impact of weight on quality of life (IWQOL)-Lite is a 31-item, self-report, obesity-specific measure of health-related quality of life (HRQOL) that consists of a total score and scores on each of five scales--physical function, self-esteem, sexual life, public distress, and work--and that exhibits strong psychometric properties. This study was undertaken in order to assess test-retest reliability and discriminant validity in a heterogeneous sample of individuals not in treatment. Individuals were recruited from the community to complete questionnaires that included the IWQOL-Lite, SF-36, Rosenberg self-esteem (RSE) scale, Marlowe-Crowne social desirability scale, global ratings of quality of life, and sexual functioning and public distress ratings. Persons currently enrolled in weight loss programs or with a body mass index (BMI) of less than 18.5 were dropped from the analyses, leaving 341 females and 153 males for analysis, with an average BMI of 27.4. For test-retest reliability, 112 participants completed the IWQOL-Lite again. ANOVA revealed significant main effects for BMI for all IWQOL-Lite scales and total score. Females showed greater impairment than males on all scales except public distress. Internal consistency ranged from 0.816 to 0.944 for IWQOL-Lite scales and was 0.958 for total score. Test-retest reliability ranged from 0.814 to 0.877 for scales and was 0.937 for total score. Internal consistency and test-retest results for overweight/obese subjects were similar to those obtained for the total sample. There was strong evidence for convergent and discriminant validity of the IWQOL-Lite in overweight/obese subjects. As in previous studies conducted on treatment-seeking obese persons, the IWQOL-Lite appears to be a reliable and valid measure of obesity-specific quality of life in overweight/obese persons not seeking treatment.

    The Workload Management System is the gLite service supporting the distributed production and analysis activities of various HEP experiments. It is responsible of dispatching computing jobs to remote computing facilities by matching job requirements and the resource status information collected from the Grid information services. Given the distributed and heterogeneous nature of the Grid, the monitoring of the job lifecycle and of the aggregate workflow patterns generated by multiple user communities, and the reliability of the service are of great importance. In this paper we deal with the problem of WMS monitoring and management. We present the architecture and implementation of the WMSMonitor, a tool for WMS monitoring and management, which has been designed to meet the needs of various WMS user categories: administrators, developers, advanced Grid users and performance testers. The tool was successfully deployed to monitor the progress of WMS job submission activities during HEP computing challenges. We also describe how, for each WMS in a cluster, WMSMonitor produces status indexes and a load metric that can be used for automated notification of critical events via Nagios, or for ranking of service instances deployed in load balancing mode.

    Mobile telephones have significant potential for use in psychological research, possessing unique characteristics-not least their ubiquity--that may make them useful tools for psychologists. We examined whether it is possible to measure reaction times (RTs) accurately using Adobe Flash Lite on mobile phones. We ran simple and choice RT experiments on two widely available mobile phones, a Nokia 6110 Navigator and a Sony Ericsson W810i, using a wireless application protocol (WAP) connection to access the Internet from the devices. RTs were compared within subjects with those obtained using a Linux-based millisecond-accurate measurement system. Results show that measured RTs were significantly longer on mobile devices, and that overall RTs and distribution of RTs varied across devices.

    3D Monte Carlo transport codes are extensively used in neutronic analysis, especially in radiation protection and shielding analyses for fission and fusion reactors. TRIPOLI-4{sup ®} is a Monte Carlo code developed by CEA. The aim of this paper is to show its capability to model a large-scale fusion reactor with complex neutron source and geometry. A benchmark between MCNP5 and TRIPOLI-4{sup ®}, on the ITER A-lite model was carried out; neutron flux, nuclear heating in the blankets and tritium production rate in the European TBMs were evaluated and compared. The methodology to build the TRIPOLI-4{sup ®} A-lite model is based on MCAM and the MCNP A-lite model. Simplified TBMs, from KIT, were integrated in the equatorial-port. A good agreement between MCNP and TRIPOLI-4{sup ®} is shown; discrepancies are mainly included in the statistical error.

    The SIM Lite Astrometric Observatory will be the first space-based Michelson interferometer operating in the visible wavelength, with the ability to perform ultra-high precision astrometric measurements on distant celestial objects. SIM Lite data will address in a fundamental way questions such as characterization of Earth-mass planets around nearby stars. To accomplish these goals it is necessary to rely on a model-based systems engineering approach - much more so than most other space missions. This paper will describe in further detail the components of this end-to-end performance model, called "SIM-sim", and show how it has helped the systems engineering process.

    This paper represents a progress report on HyLite (Hypermedia Library technology): a research and development activity to produce a versatile system as part of NASA's technology thrusts in automation, information sciences, and communications. HyLite can be used as a system or tool to facilitate the creation and maintenance of large distributed electronic libraries. The contents of such a library may be software components, hardware parts or designs, scientific data sets or databases, configuration management information, etc. Proliferation of computer use has made the diversity and quantity of information too large for any single user to sort, process, and utilize effectively. In response to this information deluge, we have created HyLite to enable the user to process relevant information into a more efficient organization for presentation, retrieval, and readability. To accomplish this end, we have incorporated various AI techniques into the HyLite hypermedia engine to facilitate parameters and properties of the system. The proposed techniques include intelligent searching tools for the libraries, intelligent retrievals, and navigational assistance based on user histories. HyLite itself is based on an earlier project, the Encyclopedia of Software Components (ESC) which used hypermedia to facilitate and encourage software reuse.

    VanDalsem, William R.; Livingston, Mary E.; Melton, John E.; Torres, Francisco J.; Stremel, Paul M.

    1999-01-01

    Continuous improvement of aerospace product development processes is a driving requirement across much of the aerospace community. As up to 90% of the cost of an aerospace product is committed during the first 10% of the development cycle, there is a strong emphasis on capturing, creating, and communicating better information (both requirements and performance) early in the product development process. The community has responded by pursuing the development of computer-based systems designed to enhance the decision-making capabilities of product development individuals and teams. Recently, the historical foci on sharing the geometrical representation and on configuration management are being augmented: 1) Physics-based analysis tools for filling the design space database; 2) Distributed computational resources to reduce response time and cost; 3) Web-based technologies to relieve machine-dependence; and 4) Artificial intelligence technologies to accelerate processes and reduce process variability. The Advanced Design Technologies Testbed (ADTT) activity at NASA Ames Research Center was initiated to study the strengths and weaknesses of the technologies supporting each of these trends, as well as the overall impact of the combination of these trends on a product development event. Lessons learned and recommendations for future activities are reported.

    Orlov, Sergei S.; Abarzhi, Snezhana I.; Oh, Se Baek; Barbastathis, George; Sreenivasan, Katepalli R.

    2010-01-01

    Modern technologies offer new opportunities for experimentalists in a variety of research areas of fluid dynamics. Improvements are now possible in the state-of-the-art in precision, dynamic range, reproducibility, motion-control accuracy, data-acquisition rate and information capacity. These improvements are required for understanding complex turbulent flows under realistic conditions, and for allowing unambiguous comparisons to be made with new theoretical approaches and large-scale numerical simulations. One of the new technologies is high-performance digital holography. State-of-the-art motion control, electronics and optical imaging allow for the realization of turbulent flows with very high Reynolds number (more than 107) on a relatively small laboratory scale, and quantification of their properties with high space–time resolutions and bandwidth. In-line digital holographic technology can provide complete three-dimensional mapping of the flow velocity and density fields at high data rates (over 1000 frames per second) over a relatively large spatial area with high spatial (1–10 μm) and temporal (better than a few nanoseconds) resolution, and can give accurate quantitative description of the fluid flows, including those of multi-phase and unsteady conditions. This technology can be applied in a variety of problems to study fundamental properties of flow–particle interactions, rotating flows, non-canonical boundary layers and Rayleigh–Taylor mixing. Some of these examples are discussed briefly. PMID:20211881

  2. The need to exchange experiences in nuclear technology

    International Nuclear Information System (INIS)

    Birkhofer, A.

    1991-01-01

    On December 7, 1965, H. Mandel invited members to the constituent session of the 'Committee for Exchanges of Operating Experience (ABE Committee)' of Working Group I of the Deutsches Atomforum. The proposal to institute regular exchanges of experience among all nuclear power plants under construction and in operation in the Federal Republic had come from A. Weckesser, Managing Director of the Gundremmingen Nuclear Power Station nearing completion at that time. The Committee was set up to improve the rather sporadic exchange of experience which had existed so far, especially with regard to the safety and availability of reactors, so that the results could be applied in practice systematically and a maximum level of operational safety could be achieved in this way. The annual reports of the 'Experiences with Nuclear Power Plants in the Federal Republic of Germany' ABE Committee were published each year in the 'atomwirtschaft' journal. In 1982, the ABE Committee was integrated into the Association of Large Power Plant Operators (Vereinigung der Grosskraftwerksbetreiber, VGB) as Technical Committee on 'Exchanges of Operating Experiences'. Twenty-five years of exchanges of experiences among German nuclear power plants have shown that the importance of such cooperation was recognized and utilized at an early point in time, even including foreign VGB members operating nuclear power plants. Improvement as a result of learning from experience and, consequently, also from past mistakes is an approach not to be followed ad libitum in the case of nuclear power plants, as the great hazard potential associated with the presence of radioactive fission products does not permit uncritical operation by trial and error. Instead, learning from experience in this case must be pursued in areas not associated with real accident hazards. This approach is perhaps best called learning in anticipation of hazards. (orig.)

    Tarfasa, Solomon; Brouwer, Roy; Sheremet, Oleg; Bouma, Jetske

    2017-10-01

    Introducing water harvesting technology is expected to be more effective and last longer if farm households are involved in their design. The main objective of this study is to inform policymakers in Ethiopia about the most important terms and conditions to incentivize farmers to enter into a contractual agreement to invest in water harvesting on their land. In order to test the influence of the way the specific contractual terms and conditions are communicated to farm households, many of whom are illiterate, a split sample approach is applied with and without visual aids for technical, institutional, and economic contract characteristics. Both samples generate significantly different results, highlighting the importance of how information is conveyed to farm households. This pattern is confirmed when examining the self-reported importance attached to the various contract characteristics. Equality Constrained Latent Class models show that contract characteristics for which visual aids were developed are considered more attentively, emphasizing the importance of adequate communication tools in a developing country context where literacy rates are limited to increase water technology innovation uptake and reduce farm household vulnerability to droughts.

  14. Moroccan experience in nuclear sciences and technology: Present status

    International Nuclear Information System (INIS)

    El Mediouri, K.

    2001-01-01

    The applications of nuclear technology started in Morocco in the early sixties and were developed particularly in the sectors of Agriculture, Education and Medicine. In the early seventies, these applications were extended to other important sectors such as Industry using gauges and NDT techniques, Mines and Hydrology. But a lack of sufficient and adequate infrastructure has limited the development of these applications. Further more, as Morocco relies totally on foreign imports to meet its energy needs, the option of nuclear power generation started to be considered seriously. This was the initiator of a real national reflection on an integrated program for all peaceful applications of nuclear energy which led to the progressive constitution of an institutional and regulatory frame. In this context, the National Center for Nuclear energy, Sciences and Techniques (CNESTEN), which is a public institution, was created in 1986. Its current programme and future are described in the paper. (author)

    Assisted reproductive technology (ART) programs are complex organizations requiring the integration of multiple disciplines. ISO 9001:2008 is a quality management system that is readily adaptable to an ART program. The value that ISO brings to the entire organization includes control of documents, clear delineation of responsibilities of staff members, documentation of the numerous processes and procedures, improvement in tracking and reducing errors, and overall better control of systems. A quality ART program sets quality objectives and monitors their progress. ISO provides a sense of transparency within the organization and clearer understanding of how service is provided to patients. Most importantly, ISO provides the framework to allow for continual improvement. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

  17. An economic perspective on experience curves and dynamic economies in renewable energy technologies

    International Nuclear Information System (INIS)

    Papineau, Maya

    2006-01-01

    This paper analyzes dynamic economies in renewable energy technologies. The paper has two contributions. The first is to test the robustness of experience in solar photovoltaic, solar thermal and wind energy to the addition of an explicit time trend, which has been done in experience studies for other industries, but not for renewable energy technologies. Estimation is carried out on the assumption that cumulative capacity, industry production, average firm production, and electricity generation affect experience and thus the fall in price. The second contribution is to test the impact of R and D on price reduction. In general cumulative experience is found to be highly statistically significant when estimated alone, and highly statistically insignificant when time is added to the model. The effect of R and D is small and statistically significant in solar photovoltaic technology and statistically insignificant in solar thermal and wind technologies

    2004-01-01

    SAMGrid is a globally distributed system for data handling and job management, developed at Fermilab for the D0 and CDF experiments in Run II. The Condor system is being developed at the University of Wisconsin for management of distributed resources, computational and otherwise. We briefly review the SAMGrid architecture and its interaction with Condor, which was presented earlier. We then present our experiences using the system in production, which have two distinct aspects. At the global level, we deployed Condor-G, the Grid-extended Condor, for the resource brokering and global scheduling of our jobs. At the heart of the system is Condor's Matchmaking Service. As a more recent work at the computing element level, we have been benefiting from the large computing cluster at the University of Wisconsin campus. The architecture of the computing facility and the philosophy of Condor's resource management have prompted us to improve the application infrastructure for D0 and CDF, in aspects such as parting with the shared file system or reliance on resources being dedicated. As a result, we have increased productivity and made our applications more portable and Grid-ready. Our fruitful collaboration with the Condor team has been made possible by the Particle Physics Data Grid

The results of laboratory research and testing of various construction materials of the Saltovo period are represented in the article: burnt and adobe bricks, tiles, ceramides, etc. The qualitative indicators of these materials and their comparative evaluations are cited. The technological parameters and processes applied in the manufacture of building ceramics are reconstructed. The methods currently used to assess the quality and to control production processes of modern building ceramics, were applied to test the archaeological samples submitted. The different kind of raw materials and finished products resulting from their usage are characterized. An attempt was made to reproduce the process of building ceramics manufacture typical of the Khazar Khaganate period using experimental archeology methods. The experimental reconstruction of manufacturing and firing of the Semikarakor-Sarkel type bricks in the laboratory and field conditions is described.

    Full Text Available We examine 4 different DON-toxin-containing (0.74 - 1.15 - 1.19 - 2.14 mg/kg winter wheat samples: they were debranned and undebranned, and we investigated the flour’s and the by-products’ (coarse, fine bran toxin content changes. SATAKE lab-debranner was used for debranning and BRABENDER lab-mill for the milling process. Without debranning, two sample flours were above the DON toxin limit (0.75 mg/kg, which are waste. By minimum debranning (and minimum debranning mass loss; 6-8%, our experience with whole flour is that the multi-stage debranning measurement significantly reduces the content of the flour’s DON toxin, while the milling by-products, only after careful consideration and DON toxin measurements, may be produced for public consumption and for feeding.

  9. Multimedia medical communication with ISDN technologies: early experiences

    1990-08-01

    ISDN provides the end user with a large number of services and the flexibility to easily modify the services they receive as their communications needs grow and change. It is our goal to use the advantages of the ISDNtechnology for a medical end user by supporting him with integrated image/voice/data information. We focus our developments to medical scenarios where general PACS concepts are not acceptable, currently or in the near future. An image/voice/data management and communications system using ISDN technology has been designed. First applications are developed - to acquire multiple image modalities such as CT, Angio and NI from several hospital departments, - to communicate with a remote image processing group (Computer Science Department), - to complement visual results wIth voice and data yielding integrated multimedia information, and - to distribute integrated multimedia information to medical end users such as surgeons and therapists. The integrated multimedia information is finally available at a specially configured PC-workstation in complete digital form. An interactive replay of this information complies with a video-standard (either NTSC or PAL) and may discard specific media-modality on demand. At any time a video copy of the complete or constituent integrated information can be saved on VHS-cassettes for further distribution. The image processing group currently creates standardized video clips for frequent surgical scenarios. This paper describes the network model for the in-house and remote ISDN communication of integrated multimedia information, traffic, and performance requirements. The flexibility and acceptance of this approach will be addressed by reviewing several surgical cases.

    While institutions have been keen to integrate information and communication technologies into medical education, little is known about the technological experiences of the current cohort of so-called 'Net Generation' students. This study investigated the technological experiences of medical students and determined whether there were differences between pre-clinical and clinical students. In 2006, 207 pre-clinical and 161 clinical students studying medicine at a major Australian university were surveyed. The questionnaire asked students about their access to, use of and skills with an array of technologies and technology-based tools. The results show that access to mobile phones, memory sticks, desktop computers, and broadband Internet connections was high while technologies such as PDAs were used in very low numbers. A factor analysis of students' use of 39 technology-based tools revealed nine clear activity types, including the 'standard' use of computers and mobile-phones, and the use of the Internet as a pastime activity, for podcasting and for accessing services. A comparison of pre-clinical and clinical students revealed a number of significant differences in terms of the frequency and skill with which these students use distinct technology-based tools. The findings inform current technology-based teaching and learning activities and shed light on potential areas of educational technology development.

    The use of interactive health technology (IHT) is a promising pathway to tackle self-management problems experienced by many chronically ill patients, including solid organ transplant (Tx) patients. Yet, to ensure that the IHT is accepted and used, a human-centered design process is needed, actively involving end users in all steps of the development process. A first critical, predevelopment step involves understanding end users' characteristics. This study therefore aims to (a) select an IHT platform to deliver a self-management support intervention most closely related to Tx patients' current use of information and communication technologies (ICTs), (b) understand Tx patients' overall willingness to use IHT for self-management support, and investigate associations with relevant technology acceptance variables, and (c) explore Tx patients' views on potential IHT features. We performed a cross-sectional, descriptive study between October and December 2013, enrolling a convenience sample of adult heart, lung, liver, and kidney Tx patients from the University Hospitals Leuven, Belgium. Broad inclusion criteria were applied to ensure a representative patient sample. We used a 35-item newly designed interview questionnaire to measure Tx patients' use of ICTs, their overall willingness to use IHT, and their views on potential IHT features, as well as relevant technology acceptance variables derived from the Unified Theory of Acceptance and Use of Technology and a literature review. Descriptive statistics were used as appropriate, and an ordinal logistic regression model was built to determine the association between Tx patients' overall willingness to use IHT, the selected technology acceptance variables, and patient characteristics. Out of 139 patients, 122 agreed to participate (32 heart, 30 lung, 30 liver, and 30 kidney Tx patients; participation rate: 88%). Most patients were male (57.4%), married or living together (68%), and had a mean age of 55.9 ± 13.4 years

  14. Experiences and Trends of Manufacturing Technology of Advanced Nuclear Fuels

    International Nuclear Information System (INIS)

    2012-08-01

    The 'Atoms for Peace' mission initiated in the mid-1950s paved the way for the development and deployment of nuclear fission reactors as a source of heat energy for electricity generation in nuclear power reactors and as a source of neutrons in non-power reactors for research, materials irradiation, and testing and production of radioisotopes. The fuels for nuclear reactors are manufactured from natural uranium (∼99.3% 238 U + ∼0.7% 235 U) and natural thorium (∼100% 232 Th) resources. Currently, most power and research reactors use 235 U, the only fissile isotope found in nature, as fuel. The fertile isotopes 238 U and 232 Th are transmuted in the reactor to human-made 239 Pu and 233 U fissile isotopes, respectively. Likewise, minor actinides (MA) (Np, Am and Cm) and other plutonium isotopes are also formed by a series of neutron capture reactions with 238 U and 235 U. Long term sustainability of nuclear power will depend to a great extent on the efficient, safe and secure utilization of fissile and fertile materials. Light water reactors (LWRs) account for more than 82% of the operating reactors, followed by pressurized heavy water reactors (PHWRs), which constitute ∼10% of reactors. LWRs will continue to dominate the nuclear power market for several decades, as long as economically viable natural uranium resources are available. Currently, the plutonium obtained from spent nuclear fuel is subjected to mono recycling in LWRs as uranium-plutonium mixed oxide (MOX), containing up to 12% PuO 2 , in a very limited way. The reprocessed uranium (RepU) is also re-enriched and recycled in LWRs in a few countries. Unfortunately, the utilization of natural uranium resources in thermal neutron reactors is 2 and MOX fuel technology has matured during the past five decades. These fuels are now being manufactured, used and reprocessed on an industrial scale. Mixed uranium- plutonium monocarbide (MC), mononitride (MN) and U-Pu-Zr alloys are recognized as advanced fuels

  18. Technology learning in a global - local perspective: - the interplay between technology diffusion, niche markets and experience curves

    International Nuclear Information System (INIS)

    Martinsen, Thomas

    2010-01-01

    Preventing dangerous global climate change requires timely deployment of nascent energy technologies with zero or low Co2 emissions. Managing the shift to a common sustainable technology path calls for insight about the influence of global technological change on the national energy system. Moreover, national policies are required to promote the shift to the new technology path. This calls for methods to analyse the national energy system within a global perspective. The objective of the work presented in this thesis was to investigate interplay between technology diffusion, niche markets and technology learning from the perspective of a small open economy like Norway. More specifically, develop methods to include the influence of technology learning manifested in experience and learning curves into national energy-economy-environment models. Moreover, apply the methods to investigate the potential influence and sensitivity to technology learning in a small open economy. In this thesis three such methods have been developed, applied and its importance assessed using Norway as an example. In this work three models have been linked. They are the global Energy Technology Perspectives model operated by the International Energy Agency, the Norwegian Markal model at the Institute for Energy Technology and the macro economic model MSG6 at Statistics Norway. Method one and two has been developed to manage the interplay between the models. In a local perspective technology learning in the global market is perceived as spillover. Based upon a review of the characteristics of technological change and learning curves and its application to energy system modelling some criteria important for the parameterization and modelling of spillover in a small open economy are suggested. The first method incorporates spillover into the national Markal model. The second method establishes a soft-link between the national models. The soft-link served two purposes; to provide input on demand

    In this paper we describe the use of CREAM and CEMonitor services for job submission and management within the gLite Grid middleware. Both CREAM and CEMonitor address one of the most fundamental operations of a Grid middleware, that is job submission and management. Specifically, CREAM is a job management service used for submitting, managing and monitoring computational jobs. CEMonitor is an event notification framework, which can be coupled with CREAM to provide the users with asynchronous job status change notifications. Both components have been integrated in the gLite Workload Management System by means of ICE (Interface to CREAM Environment). These software components have been released for production in the EGEE Grid infrastructure and, for what concerns the CEMonitor service, also in the OSG Grid. In this paper we report the current status of these services, the achieved results, and the issues that still have to be addressed.

    There is an urgent need to capture metadata on the rapidly growing number of genomic, metagenomic and related sequences, such as 16S ribosomal genes. This need is a major focus within the Genomic Standards Consortium (GSC), and Habitat is a key metadata descriptor in the proposed 'Minimum Information about a Genome Sequence' (MIGS) specification. The goal of the work described here is to provide a light-weight, easy-to-use (small) set of terms ('Habitat-Lite') that captures high-level information about habitat while preserving a mapping to the recently launched Environment Ontology (EnvO). Our motivation for building Habitat-Lite is to meet the needs of multiple users, such as annotators curating these data, database providers hosting the data, and biologists and bioinformaticians alike who need to search and employ such data in comparative analyses. Here, we report a case study based on semi-automated identification of terms from GenBank and GOLD. We estimate that the terms in the initial version of Habitat-Lite would provide useful labels for over 60% of the kinds of information found in the GenBank isolation-source field, and around 85% of the terms in the GOLD habitat field. We present a revised version of Habitat-Lite and invite the community's feedback on its further development in order to provide a minimum list of terms to capture high-level habitat information and to provide classification bins needed for future studies.

    By running applications and services closer to the user, edge processing provides many advantages, such as short response time and reduced network traffic. Deep-learning based algorithms provide significantly better performances than traditional algorithms in many fields but demand more resources, such as higher computational power and more memory. Hence, designing deep learning algorithms that are more suitable for resource-constrained mobile devices is vital. In this paper, we build a lightweight neural network, termed LiteNet which uses a deep learning algorithm design to diagnose arrhythmias, as an example to show how we design deep learning schemes for resource-constrained mobile devices. Compare to other deep learning models with an equivalent accuracy, LiteNet has several advantages. It requires less memory, incurs lower computational cost, and is more feasible for deployment on resource-constrained mobile devices. It can be trained faster than other neural network algorithms and requires less communication across different processing units during distributed training. It uses filters of heterogeneous size in a convolutional layer, which contributes to the generation of various feature maps. The algorithm was tested using the MIT-BIH electrocardiogram (ECG) arrhythmia database; the results showed that LiteNet outperforms comparable schemes in diagnosing arrhythmias, and in its feasibility for use at the mobile devices.

    2007-05-01

    Full Text Available Abstract Background Advances in structural biology, including structural genomics, have resulted in a rapid increase in the number of experimentally determined protein structures. However, about half of the structures deposited by the structural genomics consortia have little or no information about their biological function. Therefore, there is a need for tools for automatically and comprehensively annotating the function of protein structures. We aim to provide such tools by applying comparative protein structure annotation that relies on detectable relationships between protein structures to transfer functional annotations. Here we introduce two programs, AnnoLite and AnnoLyze, which use the structural alignments deposited in the DBAli database. Description AnnoLite predicts the SCOP, CATH, EC, InterPro, PfamA, and GO terms with an average sensitivity of ~90% and average precision of ~80%. AnnoLyze predicts ligand binding site and domain interaction patches with an average sensitivity of ~70% and average precision of ~30%, correctly localizing binding sites for small molecules in ~95% of its predictions. Conclusion The AnnoLite and AnnoLyze programs for comparative annotation of protein structures can reliably and automatically annotate new protein structures. The programs are fully accessible via the Internet as part of the DBAli suite of tools at http://salilab.org/DBAli/.

    Understanding technology dynamics, a fundamental driving factor of the evolution of energy systems, is essential for sound policy formulation and decision making. Technological change is not an autonomous process, but evolves from a number of endogenous interactions within the social system. Technologies evolve and improve only if experience with them is possible. Efforts must be devoted to improve our analytical tools concerning the treatment given to the technological variable, recognising the cumulative and gradual nature of technological change and the important role played by learning processes. This report presents a collection of works developed by the authors concerning the endogenisation of technological change in energy optimisation models, as a contribution to the Energy Technology Dynamics and Advanced Energy System Modelling Project (TEEM), developed in the framework of the Non Nuclear Energy Programme JOULE III of the European Union (DGXII). Here, learning curves, an empirically observed manifestation of the cumulative technological learning processes, are endogenised in two energy optimisation models. MARKAL, a widely used bottom-up model developed by the ETSAP programme of the IEA and ERIS, a model prototype, developed within the TEEM project for assessing different concepts and approaches. The methodological approach is described and some results and insights derived from the model analyses are presented. The incorporation of learning curves results in significantly different model outcomes than those obtained with traditional approaches. New, innovative technologies, hardly considered by the standard models, are introduced to the solution when endogenous learning is present. Up-front investments in initially expensive, but promising, technologies allow the necessary accumulation of experience to render them cost-effective.

    2013-09-01

    This paper examines how young peoples' lived experiences with personal technologies can be used to teach engineering ethics in a way which facilitates greater engagement with the subject. Engineering ethics can be challenging to teach: as a form of practical ethics, it is framed around future workplace experience in a professional setting which students are assumed to have no prior experience of. Yet the current generations of engineering students, who have been described as 'digital natives', do however have immersive personal experience with digital technologies; and experiential learning theory describes how students learn ethics more successfully when they can draw on personal experience which give context and meaning to abstract theories. This paper reviews current teaching practices in engineering ethics; and examines young people's engagement with technologies including cell phones, social networking sites, digital music and computer games to identify social and ethical elements of these practices which have relevance for the engineering ethics curricula. From this analysis three case studies are developed to illustrate how facets of the use of these technologies can be drawn on to teach topics including group work and communication; risk and safety; and engineering as social experimentation. Means for bridging personal experience and professional ethics when teaching these cases are discussed. The paper contributes to research and curriculum development in engineering ethics education, and to wider education research about methods of teaching 'the net generation'.

    This study explored the experience of children with physical disabilities using assistive technology for participation with schoolwork to gain a greater understanding of their perspectives and subjective experiences. A qualitative study involving thematic analysis of in-depth interviews of the child with a parent or significant adult. Purposeful sampling from a larger study recruited five children aged between 10 and 14 years, with differing physical disabilities who attended mainstream schools.

    Full Text Available In this paper, I report on preservice teachers’ reflections and perceptions on theirproblem-solving process in a technological context. The purpose of the study was to to investigatehow preservice teachers experience working individually in a dynamic geometry environment andhow these experiences affect their own mathematical activity when integrating content (nonroutineproblems and context (technology environment. Careful analysis of participants’ perceptionsregarding their thinking while engaged in problem solving, provided an opportunity to explorehow they explain the emergence of problem solving when working in a dynamic geometryenvironment. The two participants communicated their experience both through the lenses ofthemselves as problem solvers and as future mathematics educators. Moreover, the results of thestudy indicated that problem solving in a technology environment does not necessarily allow focuson decision-making, reflection, and problem solving processes as reported by previous research.

  15. Wright meets Markowitz: How standard portfolio theory changes when assets are technologies following experience curves

    OpenAIRE

    2017-01-01

    This paper considers how to optimally allocate investments in a portfolio of competing technologies. We introduce a simple model representing the underlying trade-off - between investing enough effort in any one project to spur rapid progress, and diversifying effort over many projects simultaneously to hedge against failure. We use stochastic experience curves to model the idea that investing more in a technology reduces its unit costs, and we use a mean-variance objective function to unders...

  19. Patients' and carers' experiences of interacting with home haemodialysis technology: implications for quality and safety.

    Science.gov (United States)

    2014-12-11

    Little is known about patients' and carers' experiences of interacting with home haemodialysis (HHD) technology, in terms of user experience, how the design of the technology supports safety and fits with home use, and how the broader context of service provision impacts on patients' use of the technology. Data were gathered through ethnographic observations and interviews with 19 patients and their carers associated with four different hospitals in the UK, using five different HHD machines. All patients were managing their condition successfully on HHD. Data were analysed qualitatively, focusing on themes of how individuals used the machines and how they managed their own safety. Findings are organised by three themes: learning to use the technology, usability of the technology, and managing safety during dialysis. Home patients want to live their lives fully, and value the freedom and autonomy that HHD gives them; they adapt use of the technology to their lives and their home context. They also consider the machines to be safe; nevertheless, most participants reported feeling scared and having to learn through mistakes in the early months of dialysing at home. Home care nurses and technicians provide invaluable support. Although participants reported on strategies for anticipating problems and keeping safe, perceived limitations of the technology and of the broader system of care led some to trade off safety against immediate quality of life. Enhancing the quality and safety of the patient experience in HHD involves designing technology and the broader system of care to take account of how individuals manage their dialysis in the home. Possible design improvements to enhance the quality and safety of the patient experience include features to help patients manage their dialysis (e.g. providing timely reminders of next steps) and features to support communication between families and professionals (e.g. through remote monitoring).

  20. The Relationship Between Digital Technology Experience, Daily Media Exposure and Working Memory Capacity

    Full Text Available Today’s youngsters interact with digital technologies to a great extent which leads scholars to question the influence of this exposure on human cognitive structure. Through resorting to digital nativity assumptions, it is presumed that cognitive architecture of the youth may change in accordance with digital technology use. In this regard, the current study investigated the relationship between digital technology experience, daily media exposure and working memory capacity of so-called digital native participants. A total of 572 undergraduate students responded to self-report measures, which addressed years of experience for 7 different digital devices and the daily time spent for 14 different digital activities. Participants’ working memory capacity was measured through the Computation Span and the Dot Matrix Test. While the former was used to measure the phonological loop capacity, the latter was used to address the visuo-spatial sketchpad capacity. Correlational analyses revealed that neither the phonological loop capacity nor the visuo-spatial sketchpad capacity was related to digital technology experience and daily media exposure. Thus, the transformative contribution of digital technology experience to human cognitive architecture could not be observed through the current measures

  13. A Qualitative Study on Transferring The Experience of Using Technology From Formal Education to Distance Education

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available With improvements in information technologies, distance education programs have become widespread. Institutions that offer distance education programs are increasing in number. Scholars who were used to face-to-face teaching began to give courses in distance education programs which entail technological teaching methods, a new teaching experience for the teachers. Formal education or face-to-face education and distance education have different dynamics. The transition to distance teaching from the first to the later involves the transmission of experiences of teaching with technology. For effective distance education, it is important to analyze the transmission of these teaching experiences. This study evaluates how faculty members' experiences with technologies in formal education are transmitted to distance education. Interviews were held with twelve scholars who have taught both formal and distance learning courses. The interviews were recorded. Content analysis method was used to obtain a deeper understanding of the data collected. It was found that the teaching materials used in the formal and distance educations were exactly the same. Some faculty members claimed that infrastructure and technical possibilities of the current system were not sufficient for the use of different teaching materials. However, this study suggests that teachers' beliefs about educational methods are the main reason that prevented the use of different teaching materials in distance education.

  18. Moral responsibility, technology, and experiences of the tragic: from Kierkegaard to offshore engineering.

    Science.gov (United States)

    Coeckelbergh, Mark

    2012-03-01

    The standard response to engineering disasters like the Deepwater Horizon case is to ascribe full moral responsibility to individuals and to collectives treated as individuals. However, this approach is inappropriate since concrete action and experience in engineering contexts seldom meets the criteria of our traditional moral theories. Technological action is often distributed rather than individual or collective, we lack full control of the technology and its consequences, and we lack knowledge and are uncertain about these consequences. In this paper, I analyse these problems by employing Kierkegaardian notions of tragedy and moral responsibility in order to account for experiences of the tragic in technological action. I argue that ascription of responsibility in engineering contexts should be sensitive to personal experiences of lack of control, uncertainty, role conflicts, social dependence, and tragic choice. I conclude that this does not justify evading individual and corporate responsibility, but inspires practices of responsibility ascription that are less 'harsh' on those directly involved in technological action, that listen to their personal experiences, and that encourage them to gain more knowledge about what they are doing. © The Author(s) 2010.

  2. Explaining experience curves for new energy technologies. A case study of liquefied natural gas

    International Nuclear Information System (INIS)

    Greaker, Mads; Lund Sagen, Eirik

    2008-01-01

    Many new energy technologies seem to experience a fall in unit price as they mature. In this paper we study the unit price of liquefying natural gas in order to make it transportable by ship to gas power installations all over the world. Our point of departure is the experience curve approach, however unlike many other studies of new energy technologies, we also seek to account for autonomous technological change, scale effects and the effects of upstream competition among technology suppliers. To our surprise we find that upstream competition is by far the most important factor contributing to the fall in unit price. With respect to the natural gas business, this may have implications for the future development in prices as the effect of increased upstream competition is temporary and likely to weaken a lot sooner than effects from learning and technological change. Another more general policy implication, is that while promoting new energy technologies, governments must not forget to pay attention to competition policy. (author)

  3. Learning to teach mathematics with technology: A survey of professional development needs, experiences and impacts

    Science.gov (United States)

    Bennison, Anne; Goos, Merrilyn

    2010-04-01

    The potential for digital technologies to enhance students' mathematics learning is widely recognised, and use of computers and graphics calculators is now encouraged or required by secondary school mathematics curriculum documents throughout Australia. However, previous research indicates that effective integration of technology into classroom practice remains patchy, with factors such as teacher knowledge, confidence, experience and beliefs, access to resources, and participation in professional development influencing uptake and implementation. This paper reports on a large-scale survey of technology-related professional development experiences and needs of Queensland secondary mathematics teachers. Teachers who had participated in professional development were found to be more confident in using technology and more convinced of its benefits in supporting students' learning of mathematics. Experienced, specialist mathematics teachers in large metropolitan schools were more likely than others to have attended technology-related professional development, with lack of time and limited access to resources acting as hindrances to many. Teachers expressed a clear preference for professional development that helps them meaningfully integrate technology into lessons to improve student learning of specific mathematical topics. These findings have implications for the design and delivery of professional development that improves teachers' knowledge, understanding, and skills in a diverse range of contexts.

  4. Nursing care in a high-technological environment: Experiences of critical care nurses.

    Tunlind, Adam; Granström, John; Engström, Åsa

    2015-04-01

    Management of technical equipment, such as ventilators, infusion pumps, monitors and dialysis, makes health care in an intensive care setting more complex. Technology can be defined as items, machinery and equipment that are connected to knowledge and management to maximise efficiency. Technology is not only the equipment itself, but also the knowledge of how to use it and the ability to convert it into nursing care. The aim of this study is to describe critical care nurses' experience of performing nursing care in a high technology healthcare environment. Qualitative, personal interviews were conducted during 2012 with eight critical care nurses in the northern part of Sweden. Interview transcripts were analysed using qualitative content analysis. Three themes with six categories emerged. The technology was described as a security that could facilitate nursing care, but also one that could sometimes present obstacles. The importance of using the clinical gaze was highlighted. Nursing care in a high technological environment must be seen as multi-faceted when it comes to how it affects CCNs' experience. The advanced care conducted in an ICU could not function without high-tech equipment, nor could care operate without skilled interpersonal interaction and maintenance of basal nursing. That technology is seen as a major tool and simultaneously as a barrier to patient-centred care. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2002-01-01

    The NASA Integrated Vehicle Health Management (IVHM) Technology Experiment for X-37 was intended to run IVHM software on-board the X-37 spacecraft. The X-37 is intended to be an unpiloted vehicle that would orbit the Earth for up to 21 days before landing on a runway. The objectives of the experiment were to demonstrate the benefits of in-flight IVHM to the operation of a Reusable Launch Vehicle, to advance the Technology Readiness Level of this IVHM technology within a flight environment, and to demonstrate that the IVHM software could operate on the Vehicle Management Computer. The scope of the experiment was to perform real-time fault detection and isolation for X-37's electrical power system and electro-mechanical actuators. The experiment used Livingstone, a software system that performs diagnosis using a qualitative, model-based reasoning approach that searches system-wide interactions to detect and isolate failures. Two of the challenges we faced were to make this research software more efficient so that it would fit within the limited computational resources that were available to us on the X-37 spacecraft, and to modify it so that it satisfied the X-37's software safety requirements. Although the experiment is currently unfunded, the development effort had value in that it resulted in major improvements in Livingstone's efficiency and safety. This paper reviews some of the details of the modeling and integration efforts, and some of the lessons that were learned.

While nursing practice is interwoven with technology, much of the literature in this area is speculative. Moreover, there is a debate as to whether and how 'high tech' and 'high touch' are reconcilable; this orientation is referred to as the optimism vs. pessimism debate. On a personal level, the motivation for this study came from the author's 13 years' experience in the critical care area. Following ethical approval, 10 experienced nurses from two cardiothoracic critical care units in Ireland participated in the study. A Heideggerian phenomenological methodology was used. Data collection consisted of unstructured interviews. A method of data analysis described by Walters was used. The findings provide research-based evidence to illuminate further the optimistic/pessimistic debate on technology in nursing. While the study demonstrates that the debate is far from resolved, it reveals a new finding: life-saving technology that supports the lives of critically ill patients can bring experienced nurses very close to their patients/families. The three main themes that emerged: 'alien environment', 'pulling together' and 'sharing the journey' were linked by a common thread of caring. Experienced critical care nurses are able to transcend the obtrusive nature of technology to deliver expert caring to their patients. However, the journey to proficiency in technology is very demanding and novice nurses have difficulty in caring with technology. Relevance to clinical practice. It is recommended that more emphasis be placed on supporting, assisting and educating inexperienced nurses in the critical care area and that the use of technology in nursing be given serious consideration.

    2009-01-01

    Nowadays public acceptance is the most frequent keyword used in the Brazilian nuclear scenario with the revival of the nuclear program, in which the construction of more nuclear power plants and a national radioactive waste repository are expected. The acceptance of such activities is tightly linked to a strategic communication plan, the effective tool to be implemented if success is intended. Isolated communication actions are being done in the nuclear area and this paper presents one example of them, describing the experience with college students from two educational institutions, who attended the lecture 'Nuclear technology: prejudice, fundamentals, applications and challenges'. Opinion surveys were done before and after each event, to know the opinions towards nuclear technology. The surveys were based on the choice of three words from about 10 not ordered stimulating keywords and each participant was invited to choose the first three ones that could represent the image he/she had when faced with the theme 'nuclear technology'. The lecture included topics covering positive and negative points of the nuclear technology. The measured results after the lectures shown positive perspective in the first images associated with the nuclear technology, despite focus on accidents was given in the final part of the event. The results show that some effectiveness on the target public was achieved in terms of bringing new perceptions on this technology. It is expected that this article can contribute somehow to the discussion of public acceptance of nuclear technology in Brazil. (author)

  15. Solar Alpha Rotary Joint (SARJ) Lubrication Interval Test and Evaluation (LITE). Post-Test Grease Analysis

    The Solar Alpha Rotary Joint (SARJ) is a mechanism of the International Space Station (ISS) that orients the solar power generating arrays toward the sun as the ISS orbits our planet. The orientation with the sun must be maintained to fully charge the ISS batteries and maintain all the other ISS electrical systems operating properly. In 2007, just a few months after full deployment, the starboard SARJ developed anomalies that warranted a full investigation including ISS Extravehicular Activity (EVA). The EVA uncovered unexpected debris that was due to degradation of a nitride layer on the SARJ bearing race. ISS personnel identified the failure root-cause and applied an aerospace grease to lubricate the area associated with the anomaly. The corrective action allowed the starboard SARJ to continue operating within the specified engineering parameters. The SARJ LITE (Lubrication Interval Test and Evaluation) program was initiated by NASA, Lockheed Martin, and Boeing to simulate the operation of the ISS SARJ for an extended time. The hardware was designed to test and evaluate the exact material components used aboard the ISS SARJ, but in a controlled area where engineers could continuously monitor the performance. After running the SARJ LITE test for an equivalent of 36+ years of continuous use, the test was opened to evaluate the metallography and lubrication. We have sampled the SARJ LITE rollers and plate to fully assess the grease used for lubrication. Chemical and thermal analysis of these samples has generated information that has allowed us to assess the location, migration, and current condition of the grease. The collective information will be key toward understanding and circumventing any performance deviations involving the ISS SARJ in the years to come.

    La neuromyélite optique de Devic est une pathologie inflammatoire démyélinisante du système nerveux central qui affecte électivement la moelle spinale, le nerf optique et les régions cérébrales à haute expression d’antigènes aquaporine 4. Il s’agit d’une pathologie auto-immune sévère due à des auto-anticorps dirigés contre l’aquaporine 4, à taux de morbidité et de mortalité élevé. Contrairement à d’autres pathologies inflammatoires notamment la sclérose en plaques ou polyarthrite rhumatoïde, la grossesse n’exerce aucune influence sur l’activité de la neuromyélite optique d’où la nécessité d’instaurer un traitement de fond durant toute la grossesse. La corticothérapie représente le traitement de premier choix de la neuromyélite optique durant la grossesse. D’autres traitements peuvent également être utilisés notamment le rituximab, certains immunosuppresseurs, les immunoglobulines. Le traitement par immunosuppresseurs ou rituximab est proposé lorsque la corticothérapie au long cours est contre-indiquée ou en cas d’inefficacité à celle-ci ou encore lorsque les effets secondaires sont intolérables. Les immunoglobulines sont administrées en cas de poussées sévères de la neuromyélite optique qui ne répondent pas aux bolus de methylprednisolone. Les immunoglobulines peuvent également être poursuivies seules à la dose 0,4g/kg/j toutes les 6 à 8 semaines jusqu’à l’accouchement. La plasmaphérèse est également une bonne alternative aux bolus de methylprednisolone lorsque les poussées sont très sévères. PMID:27800085

    Full Text Available The purpose of this article is to investigate both digital and non-digital technologies used to promote the sharing of learning experiences in learning through research in Basic Education. For such, a qualitative approach was followed, with data being gathered through a semistructured interview with seven Basic Education teachers working in different areas (History, Pedagogy, Computing and Geography in both public and private schools in the Vale do Taquari/RS/BRA region. Moreover, the individuals involved are undergraduate Master Degree at the Post-Graduation Teaching Program at a Higher Education Institution. Content analysis was used to analyze the gathered data. The theoretical foundation used for this study is based on the teaching through research presumptions and in the relation between technology and pedagogical practices. The collected data allowed for the construction of two analysis categories: a learning experiences shared through immaterial technological resources; b learning experiences shared through material technological resources. The results point towards the importance of producing posters and panels, as well as using the digital board, the Internet, game assembly programs and animations together with the teaching and learning processes in Basic Education.

  2. Experiences of using mobile technologies and virtual field tours in Physical Geography: implications for hydrology education

    2012-05-01

    Full Text Available Education in hydrology is changing rapidly due to diversification of students, emergent major scientific and practical challenges that our discipline must engage with, shifting pedagogic ideas and higher education environments, the need for students to develop new discipline specific and transferrable skills, and the advent of innovative technologies for learning and teaching. This paper focuses on new technologies in the context of learning and teaching in Physical Geography and reflects on the implications of our experiences for education in hydrology. We evaluate the experience of designing and trialling novel mobile technology-based field exercises and a virtual field tour for a Year 1 undergraduate Physical Geography module at a UK university. The new exercises are based on using and obtaining spatial data, operation of meteorological equipment (explained using an interactive DVD, and include introductions to global positioning systems (GPS and geographical information systems (GIS. The technology and exercises were well received in a pilot study and subsequent rolling-out to the full student cohort (∼150 students. A statistically significant improvement in marks was observed following the redesign. Although the students enjoyed using mobile technology, the increased interactivity and opportunity for peer learning were considered to be the primary benefits by students. This is reinforced further by student preference for the new interactive virtual field tour over the previous "show-and-tell" field exercise. Despite the new exercises having many advantages, exercise development was not trivial due to the high start-up costs, the need for provision of sufficient technical support and the relative difficulty of making year-to-year changes (to the virtual field tour in particular. Our experiences are highly relevant to the implementation of novel learning and teaching technologies in hydrology education.

    Several public health education programs and government agencies across the country have started offering virtual or online training programs in emergency preparedness for people who are likely to be involved in managing or responding to different types of emergency situations such as natural disasters, epidemics, bioterrorism, etc. While such online training programs are more convenient and cost-effective than traditional classroom-based programs, their success depends to a great extent on the underlying technological environment. Specifically, in an online technological environment, different types of user experiences come in to play-users' utilitarian or pragmatic experience, their fun or hedonic experience, their social experience, and most importantly, their usability experience-and these different user experiences critically shape the program outcomes, including course completion rates. This study adopts a multi-disciplinary approach and draws on theories in human computer interaction, distance learning theories, usability research, and online consumer behavior to evaluate users' experience with the technological environment of an online emergency preparedness training program and discusses its implications for the design of effective online training programs. . Data was collected using a questionnaire from 377 subjects who had registered for and participated in online public health preparedness training courses offered by a large public university in the Northeast. Analysis of the data indicates that as predicted, participants had higher levels of pragmatic and usability experiences compared to their hedonic and sociability experiences. Results also indicate that people who experienced higher levels of pragmatic, hedonic, sociability and usability experiences were more likely to complete the course(s) they registered for compared to those who reported lower levels. The study findings hold important implications for the design of effective online emergency

    This article analyzes nanotechnology as an experiment in democratic deliberation, one that seems motivated both by a desire to improve deliberative democracy and to protect the technology from undue public interference. However, rather than involving amplified (overstated) risks, nanotechnology appears to involve attenuated (understated) risks. Results from a 3-year panel study are presented to illustrate the ways in which citizens form opinions about nanotechnology, supporting the assertion that public opinion about complex technology can be both reasonable and stable. Nevertheless, the authors also voice concern that, in the absence of public pressure, risk regulation may not evolve as swiftly as it should to protect both society and industry.

  6. Using Inertial Sensors in Smartphones for Curriculum Experiments of Inertial Navigation Technology

    2015-03-01

    Full Text Available Inertial technology has been used in a wide range of applications such as guidance, navigation, and motion tracking. However, there are few undergraduate courses that focus on the inertial technology. Traditional inertial navigation systems (INS and relevant testing facilities are expensive and complicated in operation, which makes it inconvenient and risky to perform teaching experiments with such systems. To solve this issue, this paper proposes the idea of using smartphones, which are ubiquitous and commonly contain off-the-shelf inertial sensors, as the experimental devices. A series of curriculum experiments are designed, including the Allan variance test, the calibration test, the initial leveling test and the drift feature test. These experiments are well-selected and can be implemented simply with the smartphones and without any other specialized tools. The curriculum syllabus was designed and tentatively carried out on 14 undergraduate students with a science and engineering background. Feedback from the students show that the curriculum can help them gain a comprehensive understanding of the inertial technology such as calibration and modeling of the sensor errors, determination of the device attitude and accumulation of the sensor errors in the navigation algorithm. The use of inertial sensors in smartphones provides the students the first-hand experiences and intuitive feelings about the function of inertial sensors. Moreover, it can motivate students to utilize ubiquitous low-cost sensors in their future research.

    Assistive technology for computer access can be used to facilitate people with a spinal cord injury to utilize mainstream computer applications, thereby enabling participation in a variety of meaningful occupations. The aim of this study was to gain an understanding of the experiences of clients with tetraplegia trialing assistive technologies for computer access during different stages in a public rehabilitation service. In order to explore the experiences of clients with tetraplegia trialing assistive technologies for computer use, qualitative methodology was selected. Data were collected from seven participants using semi-structured interviews, which were audio-taped, transcribed and analyzed thematically. Three main themes were identified. These were: getting back into life, assisting in adjusting to injury and learning new skills. The findings from this study demonstrated that people with tetraplegia can be assisted to return to previous life roles or engage in new roles, through developing skills in the use of assistive technology for computer access. Being able to use computers for meaningful activities contributed to the participants gaining an enhanced sense of self-efficacy, and thereby quality of life. Implications for Rehabilitation Findings from this pilot study indicate that people with tetraplegia can be assisted to return to previous life roles, and develop new roles that have meaning to them through the use of assistive technologies for computer use. Being able to use the internet to socialize, and complete daily tasks, contributed to the participants gaining a sense of control over their lives. Early introduction to assistive technology is important to ensure sufficient time for newly injured people to feel comfortable enough with the assistive technology to use the computers productively by the time of discharge. Further research into this important and expanding area is indicated.

    A big affection of the rock environment and groundwaters occurred during the chemical mining of uranium in the years 1966 to 1996 in the neighbourhood of the town Straz pod Ralskem in the Czech Republic. It is necessary to clean the residual technological solutions (RTS) from the underground. The pH of the solutions in some places is still less than 2 and the concentration of sulphates reaches up to 65 g/l. The remedial activities consist of pumping of the RTS from the ground and reprocessing of the RTS in the surface technologies. The implementation of the new neutralization technologies NDS ML and NDS 10 help us with increasing of the efficiency of the remedial process. The NDS ML technology ('Mother liquor reprocessing station') started its operation in 2009 and it processes the concentrated technological solution from the evaporation station after the alum crystallization (mother liquor) with the concentration of total dissolved solids up to 250 g/l. The principle is the neutralization of the acid solutions with the aid of the lime milk. The suspension is then filtrated in the filter press, the filter cake is deposited in the tailings pond and the filtrate is injected back into the underground rock environment. The NDS 10 technology ('Neutralization and Decontamination Station NDS 10') started its operation in 2012 and it works on the same technological principle as the NDS ML station. The difference is that the NDS 10 station can process higher volume (4.4 m 3 /min) of the RTS with lower concentration of total dissolved solids 20 - 25 g/l. This poster describes the experiences of the state enterprise DIAMO with putting of these two neutralization technologies into operation and with using of the lime milk neutralization in such a large scale.

    The complexity of modern industrial processes and the large amount of data available to their operators make it difficult to monitor their status and diagnose potential failures. Although there have been many attempts to apply knowledge-based technologies to this problem, there have not been any convincing success. This paper describes recent experiences with a technology that combines artificial intelligence and simulation techniques for building real-time monitoring and diagnosis systems. A prototype system for monitoring and diagnosing the feedwater system of a nuclear power plant built using this technology is described. The paper then describes several interesting classes of failures that the prototype is capable of diagnosing. (author). 19 refs, 6 figs

    DIAMO, state owned enterprise, has a wide experience in uranium mining with the use of classical deep mining, acid in situ leaching and uranium ore processing. The sandstone deposits in Straz block have been exploited since 1968. Geological and hydrogeological conditions of the deposits and the short distance between the deep mine and ISL wellfields requires pumping huge amounts of fresh and/or acid mine water, their treatment and subsequent discharge into streams. DIAMO developed and applied several technologies for different types of wastewater treatment from the start of mining. Practically all of these technologies are used in the current phase of uranium deposit restoration after mining. It is possible to apply these technologies both in the production phase and during the restoration of underground water. In some cases, it is very desirable to combine two or several of them.

    Primordial gravitational waves generated by inflation have produced an odd-parity pattern B-mode in the cosmic microwave background (CMB) polarization. LiteBIRD (Light satellite for the studies of B-mode polarization and Inflation from cosmic background Radiation Detection) aims at detecting this B-mode polarization precisely. It requires about 2000 detectors capable of detecting a frequency range from 50 GHz to 250 GHz with ultra low noise. Superconducting detectors are suitable for this requirement. We have fabricated and tested microwave kinetic inductance detectors (MKIDs) and developed a new readout system. We have designed antenna-coupled MKIDs. Quasi-particles are created by incident radiation and are detected as a change of the surface impedance of a superconductor strip. This change of the surface impedance is translated into the change of the resonant frequency of a microwave signal transmitted through the resonator. We also have developed a new readout system for MKIDs. The newly developed readout system is not only able to read out the amplitude and the phase data with the homodyne detection for multi-channels, but also provides a unique feature of tracking the resonant frequency of the target resonator. This mechanism enables us to detect signals with a large dynamic range. We report on the recent R and D status of the developing MKIDs and on the read-out system for LiteBIRD.

    The United States has a long and successful history of cooperation with treaty partners in monitoring and verification. For strategic arms reduction treaties, our collaboration has resulted in the development and application of systems with limited complexity and intrusiveness. As we progress beyond New START (NST) along the 'road to zero', the reduced number of nuclear weapons is likely to require increased confidence in monitoring and verification techniques. This may place increased demands on the technology to verify the presence of a nuclear weapon and even confirm the presence of a certain type. Simultaneously, this technology must include the ability to protect each treaty partner's sensitive nuclear weapons information. Mutual development of this technology by treaty partners offers the best approach for acceptance in treaty negotiations. This same approach of mutual cooperation and development is essential for developing nuclear test monitoring technology in support of the Comprehensive Nuclear Test Ban Treaty (CTBT). Our ability to detect low yield and evasive testing will be enhanced through mutually developed techniques and experiments using laboratory laser experiments and high explosives tests in a variety of locations and geologies.

    Pregnancies achieved through medical treatments following a period of infertility may demand extra emotional and practical investment from women. This paper aims at understanding the experience of pregnancy after Assisted Reproductive Technology, and exploring whether this experience is affected by previous failed infertility treatments. This paper uses a qualitative approach. Participants were nineteen expectant first-time mothers from Brazil who conceived through Assisted Reproductive Technology treatment. During the third trimester of gestation, a semi-structured interview was administered to assess perceptions of and feelings about treatment and pregnancy. Interview transcripts were analysed using thematic analysis, and the sample was divided into two groups according to whether it was the participant's first treatment or not. Themes identified include: tolerance of the demands of treatment and pregnancy, consideration of the mechanics of treatment and pregnancy, and emotionally painful aspects of treatment and pregnancy. Pregnancy itself was regarded as a reward or compensation for the difficulties undergone. Perspectives differed according to whether pregnancy followed the first Assisted Reproductive Technology treatment; those who had undergone previously unsuccessful treatments focused less on the mechanical aspects of the process but were more concerned about possible physical problems. The similarities and differences found according to number of treatments attempted should be taken into consideration when providing psychological support for expectant Assisted Reproductive Technology mothers.

    Electron beam flue gas treatment technology is one of the most advanced technologies among new generation air pollution control processes. It is the only one process for simultaneous removal of SO 2 and NO x , applied in the industrial scale. Moreover other pollutants as acidic compounds, VOC and dioxins can be removed in one step. Among the other advantages a fully usable by-product – a fertilizer is created in the process. The industrial demonstrational plant was constructed in EPS Pomorzany in Szczecin (Poland). The facility treats the flue gases of maximum flow of 270.000 Nm 3 /h, which are irradiated by four accelerators of 700 keV electron energy and 260 kW beam power each. The removal efficiency of SO 2 in this installation may reach 95%, while removal efficiency of NO x – 70%. Apart of technical analysis also economical calculations of investment and operational costs of EBFGT installations, based on the data obtained on the Polish installation, was performed. The results show that in the case of multi-pollutant control the electron beam technology is strongly competitive to conventional technologies. Description of the experiences obtained during the operation of the plant and further possibilities of the technology development are presented in this paper. (author)

    1994-01-01

    The Phillips Laboratory at the Edwards Air Force Base has developed the Advanced Space Structures Technology Research Experiment (ASTREX) facility to serve as a testbed for demonstrating the applicability of proven theories to the challenges of spacecraft maneuvers and structural control. This report describes the work performed on the ASTREX test article by Texas A&M University under contract NAS119373 as a part of the Control-Structure Interaction (CSI) Guest Investigator Program. The focus of this work is on maneuvering the ASTREX test article with compressed air thrusters that can be throttled, while attenuating structural excitation. The theoretical foundation for designing the near minimum-time thrust commands is based on the generation of smooth, parameterized optimal open-loop control profiles, and the determination of control laws for final position regulation and tracking using Lyapunov stability theory. Details of the theory, mathematical modeling, model updating, and compensation for the presence of 'real world' effects are described and the experimental results are presented. The results show an excellent match between theory and experiments.

    In this paper, the gasification conditions, the gasifier structure, the measuring system and the gasification rationale of a pilot project experiment of underground coal gasification (UCG) in the Liuzhuang Colliery, Tangshan, are illustrated. The technique of two-phase underground coal gasification is proposed. The detection of the moving speed and the length of the gasification working face is made using radon probing technology. An analysis of the experiment results indicates that the output of air gas is 3000 m 3 /h with a heating value of about 4.18 MJ/m 3 , while the output of water gas is 2000 m 3 /h with a heating value of over 11.00 MJ/m 3 , of which H 2 content is above 40% with a maximum of 71.68%. The cyclical time of two-phase underground gasification is 16 h, with 8 h for each phase. This prolongs the time when the high-heating value gas is produced. The moving speed of the gasification working face in two alternative gasifiers is identified, i.e. 0.204 and 0.487 m/d, respectively. The success of the pilot project experiment of the underground gasification reveals the strides that have been made toward the commercialization of the UCG in China. It also further justifies the reasonability and feasibility of the new technology of long channel, big section, two-phase underground gasification. A conclusion is also drawn that the technology of the pilot project experiment can be popularized in old and discarded coal mines

    The Personnel Dosimetry Operations Team at the Los Alamos National Laboratory (LANL) has accepted the LITES dosimeter reader into its suite of radiation dose measurement instruments. The LITES instrument transmits coherent light from a HeNe laser through the pertinent track etch foil and a photodiode measures the amount of light scattered by the etched tracks. A small beam stop blocks the main laser light, while a lens refocuses the scattered light into the photodiode. Three stepper motors in the current LITES system are used to position a carousel that holds 36 track etch dosimeters. Preliminary work with the LITES system demonstrated the device had a linear response in counting foils subjected to exposures up to 50 mSv (5.0 rem). The United States Department of Energy requires that annual general employee dose not exceed 50 mSv (5.0 rem). On a regular basis, LANL uses the Autoscan 60 reader system (Thermo Electron Corp.) for counting track etch dosimeters. However, LANL uses a 15 hour etch process for CR39 dosimeters, and this produces more and larger track etch pits than the 6 hour etch used by many institutions. Therefore, LANL only uses the Autoscan 60 for measuring neutron dose equivalent up to exposure levels of about 3 mSv (300 mrem). The LITES system has a measured lower limit of detection (LLD) of about 0.6 mSv (60 mrem), and it has a correlation coefficient of R 2 = 0.99 over an exposure range up to 500 mSv (50.0 rem). A series of blind studies were done using three methods: the Autoscan 60 system, manual counting by optical microscope, and the LITES instrument. A collection of track etch dosimeters of unknown NDE (neutron dose equivalent) were analyzed using the three methods, and the (PC) performance coefficient was calculated when the NDE became known. The Autoscan 60 and optical microscope methods had a combined PC = 0.171, and the LITES instrument had a PC = 0.194, where a PC less than or equal to 0.300 is considered satisfactory.

    Paediatric tonsillectomy is a common procedure and one of the first skills acquired by surgical trainees. Post-tonsillectomy bleeding is one of the most significant complications. This study examined post-tonsillectomy bleed rates associated with technology and level of surgical experience. Data were collected on all tonsillectomies performed by surgical consultants (n = 6) and trainees (n = 10) at affiliated hospitals over a nine-month period. Hospital records were audited for post-tonsillectomy bleeding re-admissions and returns to the operating theatre. A total of 1396 tonsillectomies were performed (279 by trainees, 1117 by consultant surgeons). Primary post-tonsillectomy bleed rates were equivalent between trainees and consultants. Secondary bleed rates were significantly greater for trainees (10.0 per cent) compared to consultants (3.3 per cent), as were return to operating theatre rates (2.5 per cent vs 0.7 per cent). Amongst consultants, technology used was not associated with differences in secondary post-tonsillectomy bleeding and returns to the operating theatre. Our data suggest that experience of the surgeon may have greater bearing on post-tonsillectomy bleed rates than the technology used.

The aim of the paper is to investigate modern approaches to building design that involve implementation of various energy-saving technologies in diverse climates and at different structural levels, including the levels of urban development, functionality, planning, construction and engineering. The research methodology is based on the comprehensive analysis of the advanced global expertise in the design and construction of energy-efficient high-rise buildings, with the examination of their positive and negative features. The research also defines the basic principles of energy-efficient architecture. Besides, it draws parallels between the climate characteristics of countries that lead in the field of energy-efficient high-rise construction, on the one hand, and the climate in Russia, on the other, which makes it possible to use the vast experience of many countries, wholly or partially. The paper also gives an analytical review of the results arrived at by implementing energy efficiency principles into high-rise architecture. The study findings determine the impact of energy-efficient technologies on high-rise architecture and planning solutions. In conclusion, the research states that, apart from aesthetic and compositional interpretation of architectural forms, an architect nowadays has to address the task of finding a synthesis between technological and architectural solutions, which requires knowledge of advanced technologies. The study findings reveal that the implementation of modern energy-efficient technologies into high-rise construction is of immediate interest and is sure to bring long-term benefits.

    Authentic research opportunities in the classroom are most impactful when they are student-driven and inquiry-based. These experiences are even more powerful when they involve technology and meaningful connections with scientists. In today's classrooms, activities are driven by state required skills, education standards, and state mandated testing. Therefore, programs that incorporate authentic research must address the needs of teachers. NASA's Expedition Earth and Beyond (EEAB) Program has developed a framework that addresses teacher needs and incorporates the use of technology and access to mentors to promote and enhance authentic research in the classroom. EEAB is a student involvement program that facilitates student investigations of Earth or planetary comparisons using NASA data. To promote student-led research, EEAB provides standards-aligned, inquiry-based curricular resources, an implementation structure to facilitate research, educator professional development, and ongoing support. This framework also provides teachers with the option to incorporate the use of technology and connect students with a mentor, both of which can enrich student research experiences. The framework is structured by a modeled 9-step process of science which helps students organize their research. With more schools gaining increased access to technology, EEAB has created an option to help schools take advantage of students' interest and comfort with technology by leveraging the use of available technologies to enhance student research. The use of technology not only allows students to collaborate and share their research, it also provides a mechanism for them to work with a mentor. This framework was tested during the 2010/2011 school year. Team workspaces hosted on Wikispaces for Educators allow students to initiate their research and refine their research question initially without external input. This allows teams to work independently and rely on the skills and interests of

    This study examines the role of video technology in the development of cooking skills. The study explored the views of 141 female participants on whether video technology can promote confidence in learning new cooking skills to assist in meal preparation. Prior to each focus group participants took part in a cooking experiment to assess the most effective method of learning for low-skilled cooks across four experimental conditions (recipe card only; recipe card plus video demonstration; recipe card plus video demonstration conducted in segmented stages; and recipe card plus video demonstration whereby participants freely accessed video demonstrations as and when needed). Focus group findings revealed that video technology was perceived to assist learning in the cooking process in the following ways: (1) improved comprehension of the cooking process; (2) real-time reassurance in the cooking process; (3) assisting the acquisition of new cooking skills; and (4) enhancing the enjoyment of the cooking process. These findings display the potential for video technology to promote motivation and confidence as well as enhancing cooking skills among low-skilled individuals wishing to cook from scratch using fresh ingredients.

    It is imperative to tackle the issue globally mobilizing all available policies and measures. One of the important ones among them is technology transfer and diffusion. By utilizing international co-operation, industry can promote such measures in two ways: through government policy and through industry's own voluntary initiative. Needless to say, various government policies and measures play essential role. By the same token, industry initiative can complement them. There is much literature documenting the former. On the contrary there are few on the latter. This paper sheds light on the latter. The purpose of this paper is to explore the effectiveness of global voluntary sectoral approach for technology diffusion and transfer based on steel sector experience. The goal is to contribute toward building a worldwide low-carbon society by manufacturing goods with less energy through international cooperation of each sector. The authors believe that the voluntary sectoral approach is an effective method with political and practical feasibilities, and hope to see the continued growth of more initiatives based on this approach. - Highlights: → There exist huge reduction potentials in steel industries globally. → Technology transfer and diffusion are keys to achieve reductions. → Main barriers are economic, technological and policy-related. → Case studies in overcoming barriers are discussed. → In steel industry, a voluntary sectoral approach has shown to be effective.

The aim of this study was to investigate the impact of age, cognition, self-efficacy, and technology experience on the ability of older people to perceive and use iPad tablet computers for this purpose. Twenty-eight participants were interviewed using a structured interview guide and questionnaires, and a practical test of how to use the iPad was performed. The Mini-Mental State Examination (MMSE was used to assess cognition. Cognitive deficits and low self-efficacy significantly reduced the ability of the subjects to use the smart house technology and to perceive the smart house technology service as provided. Age was unrelated to the outcome variables. Finally, technology experience had an effect on technology perception. If further research supports these findings, it should influence smart-house implementation in an elderly population, raising awareness of usability problems in older people with low self-efficacy and cognitive problems.Keywords: smart house technology, iPad, cognition, self-efficacy, technology experience, elderly

    Many people with disabilities use assistive technology devices (ATDs) for computer access. The specific focus of this exploratory study was (a) to assess the experiences, opinions, and satisfaction levels of 24 individuals with disabilities using computer-related ATDs; (b) to investigate their awareness of health risk factors related to computer usage; and (c) to examine the psychosocial impact of computer-related ATDs on users. Data were collected via telephone interviews with 24 individuals with physical disabilities who had experience using one or more ATDs. The Quebec User Evaluation with Assistive Technology instrument was used to evaluate users' satisfaction with ATDs in a number of dimensions, including their physical attributes. The Psychosocial Impact of Assistive Devices Scale measured the psychosocial impact (i.e., independence, competence, and adequacy) of an ATD on users. Additional questions were posed to gather information about user's opinions and experiences. Training appeared to be an important component for ATD users, many of whom preferred a setting to try out devices rather than group or individual training. Respondents with visual impairments revealed a higher level of adaptability versus those without visual impairments (p = .001). Additional research is needed to develop specific survey items focused on users of computer-related ATDs and the evaluation of the psychosocial impact of ATDs on computer users.

    2007-01-01

    The impact of foundry-to-foundry variability and bias conditions during irradiation on the Total Ionizing Dose (TID) response of commercial 130-nm CMOS technologies have been investigated for applications in High Energy Physics (HEP) experiments. n- and p-channel MOSFETs from three different manufacturers have been irradiated with X-rays up to more than 100 Mrad (SiO2). Even though the effects of TID are qualitatively similar, the amount of degradation is shown to vary considerably from foundry to foundry, probably depending on the processing of the STI oxide and/or doping profile in the substrate. The bias during irradiation showed to have a strong impact as well on the TID response, proving that exposure at worst case bias conditions largely overestimates the degradation a device may experience during its lifetime. Overall, our results increase the confidence that 130-nm CMOS technologies can be used in future HEP experiments even without Hardness-By-Design solutions, provided that constant monitoring of th...

    Full Text Available A technological divide exists in Zimbabwe between urban and rural schools that puts rural based students at a disadvantage. In Zimbabwe, the government, through the president donated computers to most rural schools in a bid to bridge the digital divide between rural and urban schools. The purpose of this phenomenological study was to understand the experiences of Advanced Level students using computers at two rural boarding Catholic High Schools in Zimbabwe. The study was guided by two research questions: (1 How do Advanced level students in the rural areas use computers at their school? and (2 What is the experience of using computers for Advanced Level students in the rural areas of Zimbabwe? By performing this study, it was possible to understand from the students’ experiences whether computer usage was for educational learning or not. The results of the phenomenological study showed that students’ experiences can be broadly classified into five themes, namely worthwhile (interesting experience, accessibility issues, teachers’ monopoly, research and social use, and Internet availability. The participants proposed teachers use computers, but not monopolize computer usage. The solution to the computer shortage may be solved by having donors and government help in the acquisitioning of more computers.

    The International Space Station demonstrates the greatest capabilities of human ingenuity, international cooperation and technology development. The complexity of this space structure is unprecedented; and training astronaut crews to maintain all its systems, as well as perform a multitude of research experiments, requires the most advanced training tools and techniques. Computer simulation and virtual environments are currently used by astronauts to train for robotic arm manipulations and extravehicular activities; but now, with the latest computer technologies and recent successes in areas of medical simulation, the capability exists to train astronauts for more hands-on research tasks using immersive virtual environments. We have developed a new technology, the Virtual Glovebox (VGX), for simulation of experimental tasks that astronauts will perform aboard the Space Station. The VGX may also be used by crew support teams for design of experiments, testing equipment integration capability and optimizing the procedures astronauts will use. This is done through the 3D, desk-top sized, reach-in virtual environment that can simulate the microgravity environment in space. Additional features of the VGX allow for networking multiple users over the internet and operation of tele-robotic devices through an intuitive user interface. Although the system was developed for astronaut training and assisting support crews, Earth-bound applications, many emphasizing homeland security, have also been identified. Examples include training experts to handle hazardous biological and/or chemical agents in a safe simulation, operation of tele-robotic systems for assessing and diffusing threats such as bombs, and providing remote medical assistance to field personnel through a collaborative virtual environment. Thus, the emerging VGX simulation technology, while developed for space- based applications, can serve a dual use facilitating homeland security here on Earth.

  6. New tools and technology for the study of human performance in simulator experiments

    The Halden Virtual Reality Centre has for the last four years reported a number of experiments in the area of real world application of virtual and augmented reality technology. The insights from these studies have been reviewed and reported as part of a PhD-thesis submitted at the Norwegian University of Science and Technology. This report is based on the thesis and contains a theoretical discussion of how the virtual and augmented reality technology could be used to extend human operator performance in control rooms to include co-operation with plant floor personnel and interaction with not already built equipment. This thesis suggests that new tools and technology can be used for production of relevant data and insights from the study of human performance in simulator and field experiments. It examines some of the theoretical perspectives behind data collection and human performance assessment, and argues for a high resemblance of the real world and use of subject matter expertise in simulator studies. A model is proposed, suggesting that human performance measurement should be tightly coupled to the topic of study and have a close connection to the time line. This coupling requires new techniques for continuous data collection, and eye movement tracking has been identified as a promising basis for this type of measures. One way of improving realism is to create virtual environments allowing for controlling more of the environment surrounding the test subjects. New application areas for virtual environments are discussed for use in control room and field studies. The combination of wearable computing, virtual and augmented (the use of computers to overlay virtual information onto the real world) reality provides many new possibilities to present information to operators. In two experiments, virtual and augmented reality techniques were used to visualise radiation fields for operators in a contaminated nuclear environment. This way the operators could train for

    Gazey, R.; Salman, S. K.; Aklil-D'Halluin, D. D.

    This paper aims to share the field application experience related to the development of an innovative stand-alone sustainable energy system known as the PURE project. The PURE project has been developed alongside a Knowledge Transfer Partnership (KTP) scheme, which is supported by the UK Department of Trade and Industry and executed by siGEN in collaboration with The Robert Gordon University. The system has been constructed within an industrial estate on the island of Unst in Shetland, 200 miles north of the Scottish mainland. The energy system now supplies five business properties with clean reliable power and utilises wind turbine and hydrogen technology to provide a sustainable energy source. The stored hydrogen gas generated by the system is used as an energy source for periods when electrical demand within the business properties exceeds wind turbine production. The hydrogen is also utilised as a fuel source for transportation and as a transportable energy source for mobile power generation. The paper therefore gives a detailed description of the PURE project and discusses the field experience accumulated during the development and installation of the system. It also shares a number of practical issues that had to be overcome during its integration and operation. The installation of the PURE project has resulted in a number of unexpected conclusions being identified and marks a significant step forward in the accessible deployment of this technology for community use.

    The US health care system has been slow to adopt Internet, mobile, and video technologies, which have the capability to engage patients in their own care, increase patients' access to providers, and possibly improve the quality of care while reducing costs. Nevertheless, there are some pockets of progress, including Kaiser Permanente Northern California (KPNC). In 2008 KPNC implemented an inpatient and ambulatory care electronic health record system for its 3.4 million members and developed a suite of patient-friendly Internet, mobile, and video tools. KPNC has achieved many successes. For example, the number of virtual "visits" grew from 4.1 million in 2008 to an estimated 10.5 million in 2013. This article describes KPNC's experience with Internet, mobile, and video technologies and the obstacles faced by other health care providers interested in embracing them. The obstacles include the predominant fee-for-service payment model, which does not reimburse for virtual visits; the considerable investment needed to deploy these technologies; and physician buy-in.

  19. 3D integration technology for hybrid pixel detectors designed for particle physics and imaging experiments

    Hybrid pixel detectors are now widely used in particle physics experiments and are becoming established at synchrotron light sources. They have also stimulated growing interest in other fields and, in particular, in medical imaging. Through the continuous pursuit of miniaturization in CMOS it has been possible to increase the functionality per pixel while maintaining or even shrinking pixel dimensions. The main constraint on the more extensive use of the technology in all fields is the cost of module building and the difficulty of covering large areas seamlessly. On another hand, in the field of electronic component integration, a new approach has been developed in the last years, called 3D Integration. This concept, based on using the vertical axis for component integration, allows improving the global performance of complex systems. Thanks to this technology, the cost and the form factor of components could be decreased and the performance of the global system could be enhanced. In the field of radiation imaging detectors the advantages of 3D Integration come from reduced inter chip dead area even on large surfaces and from improved detector construction yield resulting from the use of single chip 4-side buttable tiles. For many years, numerous R and centres and companies have put a lot of effort into developing 3D integration technologies and today, some mature technologies are ready for prototyping and production. The core technology of the 3D integration is the TSV (Through Silicon Via) and for many years, LETI has developed those technologies for various types of applications. In this paper we present how one of the TSV approaches developed by LETI, called TSV last, has been applied to a readout wafer containing readout chips intended for a hybrid pixel detector assembly. In the first part of this paper, the 3D design adapted to the read-out chip will be described. Then the complete process flow will be explained and, finally, the test strategy adopted and

  1. Future explosive pulse-power technology for high-energy plasma physics experiments

    1991-01-01

    A variety of high-performance pulse-power systems in the 10 to 20-MJ class have been built in the last ten years or are planned in the next 3--5 years. Such systems, using capacitive energy storage, are employed in particle beam fusion, x-ray effects, x-ray physics, and plasma physics experiments. Advances in the technology of high-energy- density capacitors over the same time period has substantially decreased the cost per joule of the basic capacitor and kept the total parts count in large systems within reason. Overall, the savings in capacitor costs has about balanced the generally increasing system costs keeping the total cost of large, high-performance systems at $1--2 per joule over the period. The next step, to 100-MJ class systems, will profit from the improvements of the last decade, but there seems little reason to project a lowering of the cost per joule. In contrast, there is every reason to expect the continuously growing system costs to outstrip any savings to be realized from improvements in capacitor technology. Over the same period, explosive pulse power systems in the 10 to 20-MJ class have been employed, routinely, in plasma physics experiments. These one- shot systems currently cost about $100 K for the generator and switching and deliver energy to a plasma physics experiment in a few microseconds. Comparing only hardware costs, such systems are competitive with capacitor systems for developmental activities involving 100--200 shots -- but not for repetitive applications involving 1000's of shots. At this rate, explosive systems are competitive systems for applications involving up to 200--500 shots. In this paper, we discuss general concepts for generators and power-conditioning systems appropriate for high-energy applications. We scope two such applications and show how explosive pulse power can address those applications. And we describe one example of an explosively powered generator suitable for 100-MJ operation

    Optimization experiment of SCR denitrification technologies on a 300MW unit was conducted. Adjustment of ammonia injection quantity of corresponding AIG was conducted after measuring the SCR export NOx concentration field in 250MW load, the distribution uniformity of NOx volume fraction at the outlet of both reactor A and B was improved significantly, where the relative standard deviation of NOx reduced respectively from 29.83% to 13.01% and 24.54% to 9.26%, simultaneously, the amount of ammonia escape of A, B reactor decrease respectively by 24.76%, 19.45%. The results of optimization experiment show that, optimal adjustment can improve the NOx concentration distribution, reduce the amount of ammonia escape in a certain extent, and judge whether the catalytic activity of the regional catalyzer is in good condition. As to the area where catalyst is ineffective, the effect of optimization experiment is limited, the catalyzer should be the timely replacement, so as to better protect downstream equipment.

    This study explores how older adults respond to audiovisual virtual reality (VR) and perceive its usefulness to their lives. Focus groups were conducted with residents of a retirement community after they viewed two audiovisual VR simulations (n = 41). Thematic analysis was used to identify patterns in responses. Older adults described positive and negative emotional reactions to aspects of the VR experience, articulated content preferences, shared ideas to improve the usability of the equipment, and identified facilitators and barriers that influenced perceived usefulness. Recommendations for improving this technology include maximizing the positive aspects of VR through increasing interactivity, facilitating socializing with friends or family, and enhancing older adults' ease of use. Desired content of simulations involved travel, continuing education, reminiscence, and self-care/therapy. Virtual reality was reviewed positively, yet modifications are necessary to facilitate optimal user experience and potential benefit for this population. As older adults are interested in using VR, especially if poor health prevents the continuation of desirable activities or new experiences, it is important to respond to older adults' preferences and remove barriers that limit use and enjoyment.

  7. Modelo analítico del efecto de PRS sobre satélites GPS

    Meza, A.; Brunini, C.; Usandivaras, J. C.

    El sistema GPS (Global Position System) es, hoy en día, la herramienta de navegación y posicionamiento más potente y lo será sin duda en la próxima década. Gran parte de su valiosa utilidad se debe a la alta precisión que permite lograr y ésta, a su vez, depende, entre otras causas, de la precisión con que se conocen las órbitas de los satélites. La presión de radiación solar (PRS) fija el límite de la precisión con que pueden calcularse en la actualidad las efemérides satelitarias. El objetivo de este trabajo es proponer una mejor resolución de este fenómeno. El modelo analítico aquí presentado, se basa en el análisis del comportamiento de los residuos de un ajuste por mínimos cuadrados en el que se utiliza el modelo de PRS propuesto por Beutler. El mismo consiste en un modelo determinista del fenómeno con dos parámetros libres. Los resultados obtenidos ponen de manifiesto que, aún después de aplicar dichos parámetros, prevalecen en los residuos efectos semidiurnos en las componentes radial,tangencial y normal. Estos resultados obtenidos se comparan con los de un trabajo desarrollado por el Instituto de Berne (Beutler et al., 1994), en el que se utilizaron como pseudo-observaciones las órbitas precisas del IGS (CODE). El intervalo de integración escogido por este centro fueron las semanas 680 y 681. En resumen se tienen arcos de 14 días para todos los satélites, donde las efemérides precisas de los mismos para los 14 días fueron utilizados como pseudo-observaciones. El modelo de fuerza que empleó dicho centro fue básicamente el tradicional en lo que respecta al modelo de las fuerzas gravitacionales, y para la PRS utilizo el modelo standard de Beutler. Los parámetros de este modelo junto con las 6 condiciones iniciales (posición y velocidad) fueron ajustados por el método general de mínimos cuadrados.

    The key to the success of nuclear information management depends on whether nuclear engineers focus their attention on such management or not. This paper focus to strategic management of nuclear technology information through the KNGR NIC experience. The present KEPCO systems on nuclear information are largely divided into four parts, which are Integrated NPP Information System, System by Business Process Reengineering for Construction, KNGR IMS and Document Management Systems of Plant DDCC. In order to accommodate effective system integration, it is not desirable that a system is subordinate to others because each system has its own work flows and practices site by site. Therefore for good NIS, the system should be developed by web-based, local computer system and bottom-up approach. NIC management have to focus on domain control, nuclear portal service and development of search engine.

    The key to the success of nuclear information management depends on whether nuclear engineers focus their attention on such management or not. This paper focus to strategic management of nuclear technology information through the KNGR NIC experience. The present KEPCO systems on nuclear information are largely divided into four parts, which are Integrated NPP Information System, System by Business Process Reengineering for Construction, KNGR IMS and Document Management Systems of Plant DDCC. In order to accommodate effective system integration, it is not desirable that a system is subordinate to others because each system has its own work flows and practices site by site. Therefore for good NIS, the system should be developed by web-based, local computer system and bottom-up approach. NIC management have to focus on domain control, nuclear portal service and development of search engine

    Taking advantage of the development of optical-fiber communication technologies, the fiber-optic gyroscope (often abbreviated FOG) started to be investigated in the mid-1970s, opening the way for a fully solid-state rotation sensor. It was firstly seen as dedicated to medium-grade applications (1 ° / h range), but today, it reaches strategic-grade performance (10-4 ° / h range) and surpasses its well-established competitor, the ring-laser gyroscope, in terms of bias noise and long-term stability. Further progresses remain possible, the challenge being the ultimate inertial navigation performance of one nautical mile per month corresponding to a long-term bias stability of 10-5 ° / h. This paper is also the opportunity to recall the historical context of Sagnac's experiment, the origin of all optical gyros. xml:lang="fr"

    Full Text Available There is growing evidence on the importance of rehabilitation interventions promoting the persistence of the sense of self in people with Alzheimer's disease (AD or other forms of dementia. Assistive Technologies (AT may contribute to the development of interventions aimed to improve adaptive responses to environmental demands. This, in turns, can promote self-awareness. At the same time AT can manage computer interfaces able to record and reproduce autobiographical multimedia contents that can be very useful during reminiscence tasks carried out during conversations with supportive staff. These tasks could promote the self-concept. Globally the AT can be of great help in setting up rehabilitation and leisure environments promoting the experience of self in people with AD and other dementias.

    To explore the nature of birthing in United States (U.S.) hospitals from 1973-2007 and to explicate and interpret common, often overlooked, birthing experiences and nursing care. A Heideggerian phenomenological approach utilizing in-depth interviews. Participants' homes in Washington, Idaho, and Oregon. A purposive sample of grand multiparaes (N = 14). Data were collected via open conversational interviews of 60-90 minutes recorded on digital media and completion of a demographic and birth attribute form. Field notes and interpretive commentary were used as additional data sources and were analyzed using an established Heideggerian approach. The participants came from diverse religious and ethical backgrounds and experienced 116 births (8.29 births per woman, 79% unmedicated), a Cesarean rate of 6%, and a breastfeeding rate of 99% with a mean duration of 12 months. Two overarching patterns emerged: pursuing the "'good birth": a safe passage for baby and being in-and-out of control: body, technology, others. Each pattern subsumed several overlapping themes. The first pattern revealed that women often desire a good birth in the safety of a hospital by navigating their options prior to and during the birth. The second pattern revealed a common, yet often unachievable, desire by all of those involved in the process to control birth. Harmonizing an exchange of ideas in a technologically advanced environment prevalent in hospitals today can increase the quality of intrapartum care. Encouraging anchored companions and promoting normal physiological birth will make hospitals places where women can experience a good birth and feel safe. © 2011 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

    Technology has the potential to impact cognition in many ways. Here we contrast two forms of technology usage: 1) media multitasking (i.e., the simultaneous consumption of multiple streams of media, such a texting while watching TV) and 2) playing action video games (a particular sub-type of video game). Previous work has outlined an association between high levels of media multitasking and specific deficits in handling distracting information, while playing action video games has been associated with enhanced attentional control. As these two factors are linked with reasonably opposing effects, failing to take them jointly into account may result in inappropriate conclusions as to the impact of technology use on attention. Across four experiments (AX-CPT, N-back, Task-switching and Filter task), testing different aspects of attention and cognition, we show that heavy media multitaskers perform worse than light media multitaskers. Contrary to previous reports though, the performance deficit was not specifically tied to distractors, but was instead more global in nature. Interestingly, participants with intermediate levels of media multitasking occasionally performed better than both light and heavy media multitaskers suggesting that the effects of increasing media multitasking are not monotonic. Action video game players, as expected, outperformed non-video game players on all tasks. However, surprisingly this was true only for participants with intermediate levels of media multitasking, suggesting that playing action video games does not protect against the deleterious effect of heavy media multitasking. Taken together this study shows that media consumption can have complex and counter-intuitive effects on attentional control. PMID:26474982

    Identifying research priorities is key to innovation and economic growth, since it informs decision makers on effectively targeting issues that have the greatest potential public benefit. As such, the process of setting research priorities is of pivotal importance for favouring the science, technology, and innovation (STI)-driven development of low- and middle-income countries. We report herein on a major cross-sectoral nationwide research priority setting effort recently carried out in Tanzania by the Tanzania Commission for Science and Technology (COSTECH) in partnership with the Council on Health Research for Development (COHRED) and the NEPAD Agency. The first of its type in the country, the process brought together stakeholders from 42 sub-sectors in science, technology, and health. The cross-sectoral research priority setting process consisted of a 'training-of-trainers' workshop, a demonstration workshop, and seven priority setting workshops delivered to representatives from public and private research and development institutions, universities, non-governmental organizations, and other agencies affiliated to COSTECH. The workshops resulted in ranked listings of research priorities for each sub-sector, totalling approximately 800 priorities. This large number was significantly reduced by an expert panel in order to build a manageable instrument aligned to national development plans that could be used to guide research investments. The Tanzania experience is an instructive example of the challenges and issues to be faced in when attempting to identify research priority areas and setting an STI research agenda in low- and middle-income countries. As countries increase their investment in research, it is essential to increase investment in research management and governance as well, a key and much needed capacity for countries to make proper use of research investments.

    2017-01-01

    Hospital-based health technology assessment (HTA) has become increasingly important in Brazil due to its strategic importance to promote adoption, incorporation, dissemination, and disinvestment of technologies. A strategy to foster hospital-based HTA was implemented in 2009 by creating hospital-based HTA nuclei (NATS) at university hospitals and other strategic hospitals. Between 2011 and 2012, we interviewed board members in twenty-three NATS located in all geographic regions of Brazil to assess their general characteristics, scientific output, and challenges. Of the total, 65 percent of the NATS belonged to teaching institutions, with 44 percent associated with federal universities. The bulk of their output was in the form of mini-HTA reports. Centers in the Southeast and South of Brazil had the highest production compared with other regions. Lack of expertise and low levels of advanced training were identified as limiting factors in the majority of centers. The experience of the initial twenty-three NATS could be considered positive and has led to the creation of new ones around Brazil. Regional disparities in workload, production, and technical training should be targeted by new policies toward hospital-based HTA in Brazil. The limits and possibilities for intensifying the strategy relate to continuous investment in priority studies, which simultaneously, allow professionals who work in hospitals to receive continued education and produce relevant HTA work in a timely manner.

    Full Text Available Microsatellites have been increasingly used as molecular marker in biodiversity conservation studies in the last years, due to two main characteristics: high level of polymorphism, and the possibility of working with low quantities of DNA which can be obtained without the sacrificing of the specie to study (non invasive samples. Microsatellite markers appear particularly useful to deal with issues such as detecting bottleneck, measuring gene flow and hybridization between populations, determining paternity, assigning individuals to their population of origin and determining population structure. This article highlights information about microsatellites (characteristics, advantages and limitations that can be used to determine if they are suitable markers to solve particular problems about an organism. It also outlines future considerations of these and other alternative markers.

    En los últimos años, la utilización de microsatélites como marcador molecular en estudios de conservación de la biodiversidad ha aumentado considerablemente, debido a dos características principales: su elevada tasa de polimorfismo y la posibilidad de poder trabajar con reducidas cantidades de ADN, que se pueden obtener sin que resulte necesario el sacrificio de ejemplares (es decir, no invasivas. Son particularmente útiles para resolver diversas cuestiones relacionadas con la conservación de la diversidad genómica, como la detección de posibles cuellos de botella, medida del flujo génico e hibridación entre poblaciones, determinación de paternidades, asignación de individuos a su población de origen y determinación de la estructura poblacional, entre otras. En este trabajo se revisa la información existente sobre microsatélites (características, ventajas y limitaciones, y en particular cuándo son más adecuados para resolver determinados problemas planteados para un organismo.

    Smart house technology using tablet computers may help older people to master activities of daily living by making it easier to perform daily tasks like controlling lights and indoor temperature throughout the house with a few keystrokes. The aim of this study was to investigate the impact of age, cognition, self-efficacy, and technology experience on the ability of older people to perceive and use iPad tablet computers for this purpose. Twenty-eight participants were interviewed using a structured interview guide and questionnaires, and a practical test of how to use the iPad was performed. The Mini-Mental State Examination (MMSE) was used to assess cognition. Cognitive deficits and low self-efficacy significantly reduced the ability of the subjects to use the smart house technology and to perceive the smart house technology service as provided. Age was unrelated to the outcome variables. Finally, technology experience had an effect on technology perception. If further research supports these findings, it should influence smart-house implementation in an elderly population, raising awareness of usability problems in older people with low self-efficacy and cognitive problems.

  6. Reducing cognitive load in the chemistry laboratory by using technology-driven guided inquiry experiments

    Science.gov (United States)

    Hubacz, Frank, Jr.

    The chemistry laboratory is an integral component of the learning experience for students enrolled in college-level general chemistry courses. Science education research has shown that guided inquiry investigations provide students with an optimum learning environment within the laboratory. These investigations reflect the basic tenets of constructivism by engaging students in a learning environment that allows them to experience what they learn and to then construct, in their own minds, a meaningful understanding of the ideas and concepts investigated. However, educational research also indicates that the physical plant of the laboratory environment combined with the procedural requirements of the investigation itself often produces a great demand upon a student's working memory. This demand, which is often superfluous to the chemical concept under investigation, creates a sensory overload or extraneous cognitive load within the working memory and becomes a significant obstacle to student learning. Extraneous cognitive load inhibits necessary schema formation within the learner's working memory thereby impeding the transfer of ideas to the learner's long-term memory. Cognitive Load Theory suggests that instructional material developed to reduce extraneous cognitive load leads to an improved learning environment for the student which better allows for schema formation. This study first compared the cognitive load demand, as measured by mental effort, experienced by 33 participants enrolled in a first-year general chemistry course in which the treatment group, using technology based investigations, and the non-treatment group, using traditional labware, investigated identical chemical concepts on five different exercises. Mental effort was measured via a mental effort survey, a statistical comparison of individual survey results to a procedural step count, and an analysis of fourteen post-treatment interviews. Next, a statistical analysis of achievement was

    NASA is planning missions to Mars every two years until 2010, these missions will rely on solar power. Sunlight on the surface of Mars is altered by airborne dust and fluctuates from day to day. The MATE flight experiment was designed to evaluate solar cell performance and will fly on the Mars 2001 surveyor Lander as part of the Mars In-Situ Propellant Production Precursor (MIP) package. MATE will measure several solar cell technologies and characterize the Martian environment's solar power. This will be done by measuring full IV curvers on solar cells, direct and global insolation, temperature, and spectral content. The lander is scheduled to launch in April 2001 and arrive on Mars in January of 2002. The site location has not been identified but will be near the equator, is a powered landing, and is baselined for 90 sols. The intent of this paper is to provide a brief overview of the MATE experiment and progress to date. The MATE Development Unit (DU) hardware has been built and has completed testing, work is beginning in the Qualification Unit which will start testing later this year, Flight Hardware is to be delivered next spring.

    Measured performance characteristics from ground test of the Transmitter Experiment Package (TEP) for the Communications Technology Satellite are presented. The experiment package consists of a 200 W Output Stage Tube (OST) powered by a Power Processing System (PPS). Descriptions of both the PPS and OST are given. The PPS provides the necessary voltages with a measured dc/dc conversion efficiency of 89 per cent. The OST, a traveling wave tube with multiple collectors, has a saturated rf output power of 224 W and operates at an overall efficiency exceeding 40 per cent over an 85 MHz bandwidth at 12 GHz. OST performance given includes frequency response, saturation characteristics, group delay, AM to PM conversion, intermodulation distortion, and two channel gain suppression. Single and dual channel FM video performance is presented. It was determined that for 12 MHz peak to peak frequency deviation on each channel, dual channel FM television signals can be transmitted through the TEP at 60 W, each channel, with 40 MHz channel spacing (center to center).

  9. EXPERIENCES OF POLISH MECHANICAL HEAT TREATMENT TECHNOLOGY APPLIED TO MUNICIPAL WASTE

    2017-08-01

    Full Text Available In Poland and in several EU countries, the processing of mixed municipal waste is based on waste treatment in mechanical and biological installations and thermal processing plants. The experience gained from the operation of these installations, particularly in the aspect of material recycling, what is important in an aspect of the circular economy formulation is not satisfactory. To think about a high level of reuse and recycling of municipal waste, which is expected to be at least 65% by 2030, efforts to improve waste quality are needed. Certainly, one of the solution is a selective collection of waste at source, but here it is important to say that it should be conducted at a real high level. How costly it is, many countries already know. In search of other methods the UK countries are turning their attention to mechanical heat treatment technology. In Poland there is one such installation so the idea of this paper is discuss issues connected with it. The practical experience of operating of this installations shows so far that the process gives an ability to match good process parameters to a variable input. The very good quality of secondary raw materials obtained in the process has a higher attractiveness to the final consumer. Also levels of recycling for the four fractions of waste, such as: paper, metals, plastics and glass are high and exceeds significantly factors achieved in the process of mechanical and biological treatment.

    The Space Technology 5(ST5) payload was successfully carried into orbit on an OSC Pegasus XL launch vehicle, which was carried aloft and dropped from the OSC Lockheed L-1011 from Vandenberg Air Force Base March 22,2006, at 9:03 am Eastern time, 6:03 am Pacific time. In order to reach the completion of the development and successful launch of ST 5, the systems integration and test(I&T) team determined that a different approach was required to meet the project requirements rather than the standard I&T approach used for single, room-sized satellites. The ST5 payload, part of NASA's New Millennium Program headquartered at JPL, consisted of three micro satellites (approximately 30 kg each) and the Pegasus Support Structure (PSS), the system that connected the spacecrafts to the launch vehicle and deployed the spacecrafts into orbit from the Pegasus XL launch vehicle. ST5 was a technology demonstration payload, intended to test six (6) new technologies for potential use for future space flights along with demonstrating the ability of small satellites to perform quality science. The main technology was a science grade magnetometer designed to take measurements of the earth's magnetic field. The three spacecraft were designed, integrated, and tested at NASA Goddard Space Flight Center with integration and environmental testing occurring in the Bldg. 7-1 0-15-29. The three spacecraft were integrated and tested by the same I&T team. The I&T Manager determined that there was insufficient time in the schedule to perform the three I&T spacecraft activities in series used standard approaches. The solution was for spacecraft #1 to undergo integration and test first, followed by spacecraft #2 and #3 simultaneously. This simultaneous integration was successful for several reasons. Each spacecraft had a Lead Test Conductor who planned and coordinated their spacecraft through its integration and test activities. One team of engineers and technicians executed the integration of all

    2003-07-01

    This thesis suggests that new tools and technology can be used for production of relevant data and insights from the study of human performance in simulator and field experiments. It examines some of the theoretical perspectives behind data collection and human performance assessment, and argues for a high resemblance of the real world and use of subject matter expertise in simulator studies. A model is proposed, suggesting that human performance measurement should be tightly coupled to the topic of study and have a close connection to the time line. This coupling requires new techniques for continuous data collection, and eye movement tracking has been identified as a promising basis for this type of measures. One way of improving realism is to create virtual environments allowing for controlling more of the environment surrounding the test subjects. New application areas for virtual environments are discussed for use in control room and field studies. The combination of wearable computing, virtual and augmented (the use of computers to overlay virtual information onto the real world) reality provides many new possibilities to present information to operators. In two experiments, virtual and augmented reality techniques were used to visualise radiation fields for operators in a contaminated nuclear environment. This way the operators could train for and execute their tasks in a way that minimised radiation exposure to the individual operator. Both experiments were successful in proving the concept of radiation visualisation. Virtual environments allow for early end-user feedback in the design and refurbishment of control room man-machine interfaces. The practical usability of VR in the control room setting was tested in two control room design experiments. The results show that with the right tools for solving the tasks under test, even desktop presentations of the virtual environment can provide sufficient resemblance of the real world.

    Kolo, Yovonda Ingram

    African American women are underrepresented in science, technology, engineering, and mathematics (STEM) fields throughout the United States. As the need for STEM professionals in the United States increases, it is important to ensure that African American women are among those professionals making valuable contributions to society. The purpose of this phenomenological study was to describe the experiences of African American young women in relation to STEM education. The research question for this study examined how experiences with STEM in K-10 education influenced African American young women's academic choices in their final years in high school. The theory of multicontextuality was used to provide the conceptual framework. The primary data source was interviews. The sample was composed of 11 African American young women in their junior or senior year in high school. Data were analyzed through the process of open coding, categorizing, and identifying emerging themes. Ten themes emerged from the answers to research questions. The themes were (a) high teacher expectations, (b) participation in extra-curricular activities, (c) engagement in group-work, (d) learning from lectures, (e) strong parental involvement, (f) helping others, (g) self-efficacy, (h) gender empowerment, (i) race empowerment, and (j) strategic recruitment practices. This study may lead to positive social change by adding to the understanding of the experiences of African American young women in STEM. By doing so, these findings might motivate other African American young women to pursue advanced STEM classes. These findings may also provide guidance to parents and educators to help increase the number of African American women in STEM.

    To manage data in the grid, with its jungle of protocols and enormous amount of data in different storage solutions, it is important to have a strong, versatile and reliable data management library. While there are several data management tools and libraries available, they all have different strengths and weaknesses, and it can be hard to decide which tool to use for which purpose. EMI is a collaboration between the European middleware providers aiming to take the best out of each middleware to create one consolidated, all-purpose grid middleware. When EMI started there were two main tools for managing data - gLite had lcg util and the GFAL library, ARC had the ARC data tools and libarcdata2. While different in design and purpose, they both have the same goal, to manage data in the grid. The design of the new EMI datalib was ready by the end of 2011, and a first prototype is now implemented and going through a thorough testing phase. This presentation will give the latest results of the consolidated library ...

    We report the discovery of two ultra-faint satellites in the vicinity of the Large Magellanic Cloud (LMC) in data from the Magellanic Satellites Survey (MagLiteS ). Situated 18 deg (˜20 kpc) from the LMC and separated from each other by only 18 arcmin, Carina II and III form an intriguing pair. By simultaneously modelling the spatial and the colour-magnitude stellar distributions, we find that both Carina II and Carina III are likely dwarf galaxies, although this is less clear for Carina III. There are in fact several obvious differences between the two satellites. While both are well described by an old and metal poor population, Carina II is located at ˜36 kpc from the Sun, with MV ˜ -4.5 and rh ˜ 90 pc, and it is further confirmed by the discovery of 3 RR Lyrae at the right distance. In contrast, Carina III is much more elongated, measured to be fainter (MV ˜ -2.4), significantly more compact (rh ˜ 30 pc), and closer to the Sun, at ˜28 kpc, placing it only 8 kpc away from Car II. Together with several other systems detected by the Dark Energy Camera, Carina II and III form a strongly anisotropic cloud of satellites in the vicinity of the Magellanic Clouds.

    Full Text Available Emprender el estudio de la élite política de Huelva y su comportamiento durante el período electoral de 1923 presenta para nosotros un doble interés. Por un lado, y en la medida en que la historia contemporánea onubense sigue siendo una gran desconocida, es nuestro objetivo contribuir a la colmatación de una extensa laguna historiográfica que requiere, con urgencia, una mayor atención de la que hasta ahora se le ha prestado. Por otro lado, y en un sentido más amplio, pretendemos proceder al análisis —en el marco de una sociedad de provincias de tipo medio— de una encrucijada histórica donde aparecen implicados fenómenos tan significativos como la crisis del sistema canovista, los planteamientos reformadores de la Concentración Liberal y el propio advenimiento de la Dictadura de Primo de Rivera.

Such a highly competitive and dynamic environment, organized to comply a business-oriented model, has already started pursuing quality criteria, thus requiring to formally define rigorous procedures, interfaces and roles for each step of the software life-cycle. This will ensure quality-certified releases and updates of the Grid middleware. In the European Middleware Initiative (EMI), the release management for one or more components will be organized into Product Team (PT) units, fully responsible for delivering production ready, quality-certified software and for coordinating each other to contribute to the EMI release as a whole. This paper presents the certification process, with respect to integration, installation, configuration and testing, adopted at INFN by the Product Team responsible for the gLite Web-Service based Computing Element (CREAM CE) and for the Workload Management System (WMS). The used resources, the testbeds layout, the integration and deployment methods, the certification steps to provide feedback to developers and to grant quality results are described.

    Full Text Available As particularidades nos instrumentos de sensoriamento remoto, mesmo quando possuem características semelhantes, torna as imagens geradas por estes, diferentes entre si. Visando isto, o objetivo do trabalho foi analisar a aplicabilidade e os limites de detecção na identificação de alvos naturais em diferentes imagens de satélites. A área de estudo está localizada no Estado de São Paulo dentro do Município de Onda Verde, os alvos naturais foram selecionados a partir de análises realizadas nas imagens e visita desses pontos em campo. Foram escolhidas áreas que apresentaram bom contraste com o entorno e fácil localização nas imagens de satélite. Para o processamento digital de imagem foi utilizado o software livre gvSIG. Neste estudo foram empregados dados de satélites de média resolução espacial como Landsat-5, CBERS-2B e IRS-P6, disponíveis na base de dados de domínio público do INPE (Instituto Nacional de Pesquisas Espaciais e imagens de alta resolução espacial dos satélites RapidEye e WorldView-2. Nos sensores de média resolução espacial, as menores resoluções espaciais dos sensores TM e LISS-3, não impediram a visualização dos alvos espectrais analisados, visto que, no CCD que possui uma maior resolução espacial, não foi possível a identificação dos alvos escolhidos. As imagens de alta resolução espacial RapidEye e WorldView apresentaram grande riqueza de detalhamento para a cobertura do solo, a isto atrela-se a alta resolução radiométrica desses satélites.

    Future missions to Mars will rely heavily on solar power from the sun, various solar cell types and structures must be evaluated to find the optimum. Sunlight on the surface of Mars is altered by air-borne dust that fluctuates in density from day to day. The dust affects both the intensity and spectral content of the sunlight. The MATE flight experiment was designed for this purpose and will fly on the Mars 2001 Surveyor Lander as part of the Mars In-Situ Propellant Production Precursor (MIP) package. MATE will measure the performance of several solar cell technologies and characterize the Martian environment in terms of solar power. This will be done by measuring full IV curves on solar cells, direct and global insolation, temperature, and spectral content. The Lander is is scheduled to launch in April 2001 and arrive on Mars in January of 2002. The site location has not been identified but will be near the equator and last from 100 to 300 days. The intent of this of this paper is to describe and update the progress on MATE. MATE has four main objectives for its mission to Mars. First is to measure the performance of solar cells daily on the surface of Mars, this will determine the day to day fluctuations in sunlight and temperature and provide a nominal power output. Second, in addition to measuring solar cell performance, it will allow for an intercomparison of different solar cell technologies. Third, It will study the long term effects of dust on the solar cells. Fourth and last, it will characterize the mars environment as viewed by the solar cell, measuring spectrum, insolation, and temperature.

    Nitrogen dioxide (NO2) is an air pollutant that has a large impact on human health and ecosystems, and it plays a key role in the formation of ozone and secondary particulate matter. Consequently, legal limit values for NO2 are set in the EU and elsewhere, and atmospheric observation networks typically include NO2 in their measurement programmes. Atmospheric NO2 is principally measured by chemiluminescence detection, an indirect measurement technique that requires conversion of NO2 into nitrogen monoxide (NO) and finally calculation of NO2 from the difference between total nitrogen oxides (NOx) and NO. Consequently, NO2 measurements with the chemiluminescence method have a relatively high measurement uncertainty and can be biased depending on the selectivity of the applied NO2 conversion method. In the past years, technologies for direct and selective measurement of NO2 have become available, e.g. cavity attenuated phase shift spectroscopy (CAPS), cavity enhanced laser absorption spectroscopy and quantum cascade laser absorption spectrometry (QCLAS). These technologies offer clear advantages over the indirect chemiluminescence method. We tested the above mentioned direct measurement techniques for NO2 over extended time periods at atmospheric measurement stations and report on our experience including comparisons with co-located chemiluminescence instruments equipped with molybdenum as well as photolytic NO2 converters. A still open issue related to the direct measurement of NO2 is instrument calibration. Accurate and traceable reference standards and NO2 calibration gases are needed. We present results from the application of different calibration strategies based on the use of static NO2 calibration gases as well as dynamic NO2 calibration gases produced by permeation and by gas-phase titration (GPT).

    on the each calibration graphics with different H2 concentration in standard gas mixtures. The graphics represent the power functions. The accuracy of the approximating functions is 3-18 %. At low concentrations (H2 make corrections, because measurements were made in wide temperature range (+29 - -20 C). To take this factor we added our network by meteorological sensors. Each sensor network node has a radio transceiver with an internal antenna or connection to an external antenna, a microcontroller, an electronic circuit for interfacing with the sensors and an energy source, usually a battery or an embedded form of energy harvesting. All nodes are equal and serve as routers, so there is no need to plan nodes placement in advance Mesh Network protocol. Every node maintains a local routing table with information about one or several neighbors. The signal transmission between nodes and router used radio channel 2.6 GHz. Communication between router and IT server used two methods: cable RS486 and GPRS modem. GPRS connection is unstable and influence on operating stability. There are some problems in using of directional antenna because of the high level of city's radio noises and radio interferences. Nevertheless, a number of experiments with use of different technical solutions allowed us to perform continuous monitoring during 2 months. As a result about 3 million data records were obtained during experimental works. This information provided an opportunity to develop the structure of database management systems to store data and the technology of online data collection from remote sensors. Using the abilities of program software a periodical (12h) automatic export/import was realized. Access to file on remote computers is opened using FTP protocol. Database forms derived tables for each sensors. We use triggers to modify data, for example, to modify signal from gas sensors to gas concentration, in depend of unique sensor name.

    New MMIS (Man Machine Interface System) technology is rapidly advanced as digital technology provides opportunity for more functionality and better cost effectiveness. Also, NPP (Nuclear Power Plant) operators are inclined to use the new technology for the construction of new plant and for the upgrade of existing plants. However, this new technology may include risks at the same time. These risks are mainly due to the poor reliability of newly developed technology. According to the user requirement (KURD: Korean Utility Requirement Document), advanced MMIS technology may be applied if it could be apparently needed to obtain a defined gain in simplicity or performance. For applying new MMIS technology, reliability needs to be verified on the basis of the requirements of proven technology. KURD suggests two methods for verifying satisfaction of the requirement of proven technology. These methods are to verity whether or not unproven MMIS technology has adequate reliability. First method is that it has at least three years of documented, satisfactory service as modules of subsystems in power plant applications similar to that in LWRs or in other than power plant applications which are similar to the use in the APR1400 M-MIS. Second method is that it has satisfactorily completed a defined program of prototype testing which has been designed to verify its performance in the APR1400 M-MIS application. But, new MMIS technology had not yet opportunity to apply in the Nuclear Power Plant. Therefore, we think that second method is the effective method to demonstrate reliability and performance of new technology through the experience accumulation test. In here, Experience accumulation test means that we emulate the process of nuclear power plant such as installation after shipping, trial operation, operation, and maintenance with MMIS facility and verify reliability and performance through various test method under the circumstance of emulation and if any problem occurs

  5. Multi-physic simulations of irradiation experiments in a technological irradiation reactor

    2007-09-01

    A Material Testing Reactor (MTR) makes it possible to irradiate material samples under intense neutron and photonic fluxes. These experiments are carried out in experimental devices localised in the reactor core or in periphery (reflector). Available physics simulation tools only treat, most of the time, one physics field in a very precise way. Multi-physic simulations of irradiation experiments therefore require a sequential use of several calculation codes and data exchanges between these codes: this corresponds to problems coupling. In order to facilitate multi-physic simulations, this thesis sets up a data model based on data-processing objects, called Technological Entities. This data model is common to all of the physics fields. It permits defining the geometry of an irradiation device in a parametric way and to associate information about materials to it. Numerical simulations are encapsulated into interfaces providing the ability to call specific functionalities with the same command (to initialize data, to launch calculations, to post-treat, to get results,... ). Thus, once encapsulated, numerical simulations can be re-used for various studies. This data model is developed in a SALOME platform component. The first application case made it possible to perform neutronic simulations (OSIRIS reactor and RJH) coupled with fuel behavior simulations. In a next step, thermal hydraulics could also be taken into account. In addition to the improvement of the calculation accuracy due to the physical phenomena coupling, the time spent in the development phase of the simulation is largely reduced and the possibilities of uncertainty treatment are under consideration.

    We drew on an interdisciplinary research design to examine stroke survivors' experiences of living with stroke and with technology in order to provide technology developers with insight into values, thoughts and feelings of the potential users of a to-be-designed robotic technology for home-based rehabilitation of the hand and wrist. Ten stroke survivors and their family carers were purposefully selected. On the first home visit, they were introduced to cultural probe. On the second visit, the content of the probe packs were used as prompt to conduct one-to-one interviews with them. The data generated was analysed using thematic analysis. A third home visit was conducted to evaluate the early prototype. User requirements were categorised into their network of relationships, their attitude towards technology, their skills, their goals and motivations. The user requirements were used to envision the requirements of the system including providing feedback on performance, motivational aspects and usability of the system. Participants' views on the system requirements were obtained during a participatory evaluation. This study showed that prior to the development of technology, it is important to engage with potential users to identify user requirements and subsequently envision system requirements based on users' views. Implications for Rehabilitation An understanding of how stroke survivors make sense of their experiences of living with stroke is needed to design home-based rehabilitation technologies. Linking stroke survivors' goals, motivations, behaviour, feelings and attitude to user requirements prior to technology development has a significant impact on improving the design.

    This presentation described Ontario Power Generation's experience in implementing a decision support tool to enable water management plans for its operations through technology solutions. All hydroelectric producers in Ontario are required to make water management plans in order to maintain water levels and flows in their operating regions. This regulation was created in response to environmental concerns as well as to changes in the electricity market and growth of residential and cottage property near water bodies. In order to keep informed and to address compliance issues, operators and managers need situation awareness information to balance operational decisions. The online Adaptive Water Management System (AWMS) decision support tool was recently adopted by Ontario Power Generation to provide information needed to address the requirements of Water Management Plans. The AWMS provides users with information on water levels and flows; the ability to implement, modify, and manage daily instructions at the facilities; track conditions in the watershed; and, provide a status of compliance. The tool was developed by 4DM Inc. in collaboration with Ottawa St. Lawrence Plant Group for the Madawaska River Watershed Management, a model partnership between operator, regulator and Public Advisory Committee to develop a water management plan.

    The processes and effects of coagulation-ultrafiltration (C-UF) and coagulation sedimentation-ultrafiltration (CS-UF) process used in the treatment of Dalangdian Reservoir water were compared. The experiment data indicated that 99% of turbidity removal and basically 100% of microorganism and algae removal were achieved in both C-UF and CS-UF process. The organic removal effect of CS-UF? process was slightly better than C-UF process. However, the organic removal effect under different processes was not obvious due to limitation of ultrafiltration membrane aperture. Polyaluminium chloride was taken as a coagulant in water plant. The aluminum ion removal result revealed that coagulant dosage was effectively saved by using membrane technology during megathermal high algae laden period. Within the range of certain reagent concentration and soaking time, air-water backwashing of every filtration cycle of membrane was conducted to effectively reduce membrane pollution. Besides, maintenance cleaning was conducted every 60 min. whether or not restorative cleaning was conducted depends on the pollution extent. After cleaning, recovery of membrane filtration effect was obvious.

    Full Text Available Aim: To analyse teachers’ experience in applying information communication technologies (from now on referred to as ICT during the study process. Methodology: The analysis is based on a qualitative research methodology determined by the novelty of the problem under analysis. Six teachers of the University X (faculty Y participating in the study were selected by applying a random sampling procedure and were interviewed by using the semi-structured interviews. Results: The research revealed that the use of ICT in the study process is still fragmented due to the lack of the teachers` ICT competence and to teaching priority given to direct communication. Because of the lack of higher level competence in ICT necessary for the efficient use of ICT tools in the study process, teachers as a rule resort to limited opportunities to increase the attractiveness of the process. Research limitations: in order to theoretically and empirically validate ICT applicationpossibilities in the study process, teachers of one faculty of one university have been interviewed. In view of this, the conclusions cannot be extended to all teachers. Practical significance: the research revealed problems faced by the university teachers in applying ICT during the study process. Identification of problems will facilitate a more efficient use of ICT in the study process, as well as the development of teachers’ qualification. Originality and value: the research provided more information on teachers` competence in using ICT.

    2001-01-01

    When studying applications in nuclear technology we need to understand and be able to predict the behavior of systems manufactured by human enterprise. First, the underlying basic physical and chemical phenomena need to be understood. We have then to predict the results from the interplay of the large number of the different basic events: i.e. the macroscopic effects. In order to be able to build confidence in our modelling capability, we need then to compare these results against measurements carried out on such systems. The different levels of modelling require the solution of different types of equations using different type of parameters. The tools required for carrying out a complete validated analysis are: - The basic nuclear or chemical data; - The computer codes, and; - The integral experiments. This article describes the role each component plays in a computational scheme designed for modelling purposes. It describes also which tools have been developed and are internationally available. The role of the OECD/NEA Data Bank, the Radiation Shielding Information Computational Center (RSICC), and the IAEA Nuclear Data Section are playing in making these elements available to the community of scientists and engineers is described.

    We have been developing a laser-cooling apparatus for flight on the International Space Station (ISS), with the intention of demonstrating linewidths on the cesium clock transition narrower than can be realized on the ground. GLACE (the Glovebox Laser- cooled Atomic Clock Experiment) is scheduled for launch on Utilization Flight 3 (UF3) in 2002, and will be mounted in one of the ISS Glovebox platforms for an anticipated 2-3 week run. Separate flight definition projects funded at NIST and Yale by the Micro- gravity Research Division of NASA as a part of its Laser Cooling and Atomic Physics (LCAP) program will follow GLACE. Core technologies for these and other LCAP missions are being developed at JPL, with the current emphasis on developing components such as the laser and optics subsystem, and non-magnetic vacuum-compatible mechanical shutters. Significant technical challenges in developing a space qualifiable laser cooling apparatus include reducing the volume, mass, and power requirements, while increasing the ruggedness and reliability in order to both withstand typical launch conditions and achieve several months of unattended operation. This work was performed at the Jet Propulsion Laboratory under a contract with the National Aeronautics and Space Administration.

    This multi-authored textbook addresses graduate students with a background in physics, mathematics or computer science. No research experience is necessary. Consequently, rather than comprehensively reviewing the vast body of knowledge and literature gathered in the past twenty years, this book concentrates on a number of carefully selected aspects of quantum information theory and technology. Given the highly interdisciplinary nature of the subject, the multi-authored approach brings together different points of view from various renowned experts, providing a coherent picture of the subject matter. The book consists of ten chapters and includes examples, problems, and exercises. The first five present the mathematical tools required for a full comprehension of various aspects of quantum mechanics, classical information, and coding theory. Chapter 6 deals with the manipulation and transmission of information in the quantum realm. Chapters 7 and 8 discuss experimental implementations of quantum information ideas using photons and atoms. Finally, chapters 9 and 10 address ground-breaking applications in cryptography and computation. (orig.)

  1. U.S. Experiences and Regulatory Challenges with New Medical Technologies

    International Nuclear Information System (INIS)

    2016-01-01

    There are many challenges in regulating new medical technologies in the United States. In the US, there are fifty different state agencies, several local and city agencies, and eleven federal agencies which all delve into some aspects of regulating the use of radiation. It also can take several years to promulgate new regulations for new technologies. Additionally, some technologies are used outside of their original approved/intended use which causes issues for regulators. Finally, many of our regulating agencies have limited resources to learn and train on the new technologies that are on the market. All of these reasons combine to make regulating new technologies and uses of radiation difficult. (author)

    The laser produced target plasma confined in the LITE minimum-B mirror magnetic field is shown along with a drawing of the confinement field line configuration. The plasma is generated by two beam, 1.06 micron, Nd-glass laser irradiation of LiH particles approximately 100 microns in diameter producing a plasma of approximately 10 16 hydrogen and lithium ions which expands in and is captured by the ''baseball'' confinement field. The plasma luminosity displays a plasma configuration which corresponds to the magnetic field geometry and indicates a plasma volume of approximately 400 cm 3 . Probe and microwave measurements confirm the plasma distribution indicated by the luminosity photographs. Charge collector probes located at a series of positions over a 120 0 arc in the mirror fan permit simultaneous observations of the plasma decay along field lines which pass through the mid-plane at different radial distances from the magnetic field axis. Plasma flux is observed with these probes to field lines 6 cm from the axis. Microwave measurements have been made with a strongly focused, 75 GHz (lambda = 4 mm) beam passing through the mid-plane, orthogonal to the mirror axis. Cut-off of the microwave beam transmission early in the confined plasma time history indicates that the radial dimension of the high density plasma region exceeds 2 cm. Measurement of the line density via interferometric measurements of the phase shift of the transmitted beam when the density has fallen below cut-off indicates an ''effective'' diameter of approximately 5 cm and an axial extent of approximately 20 cm. Thus, the plasma presents approximately 100 cm 2 target area to an incident neutral beam and occupies approximately 400 cm 3 volume

    Passive spectroscopic remote sensing of planetary atmospheres and surfaces in the thermal infrared is a powerful tool for obtaining information about surface and atmospheric temperatures, composition, and dynamics (via the thermal wind equation). Due to its broad spectral coverage, the Fourier transform spectrometer (FTS) is particularly suited to the exploration and discovery of molecular species. NASA's Goddard Space Flight Center (GSFC) developed the CIRS (Composite Infrared Spectrometer) FTS for the NASA/ESA Cassini mission to the Saturnian system. CIRS observes Saturn, Titan, icy moons such as Enceladus, and the rings in thermal self-emission over the spectral range of 7 to 1000 ell11. CIRS has given us important new insights into stratospheric composition and jets on Jupiter and Saturn, the cryo-geyser and thermal stripes on Enceladus, and the winter polar vortex on Titan. CIRS has a mass of 43 kg, contrasted with the earlier GSFC FTS, pre-Voyager IRIS (14 kg). Future low-cost planetary missions will have very tight constraints on science payload mass, thus we must endeavor to return to IRIS-level mass while maintaining CIRS-level science capabilities ("do more with less"). CIRS-lite achieves this by pursuing: a) more sensitive infrared detectors (high Tc superconductor) to enable smaller optics. b) changed long wavelength limit from 1000 to 300 microns to reduce diffraction by smaller optics. c) CVD (chemical vapor deposition) diamond beam-splitter for broad spectral coverage. d) single FTS architecture instead of a dual FTS architecture. e) novel materials, such as single crystal silicon for the input telescope primary.

    The goal of intelligent tutoring systems (ITS) that interact in natural language is to emulate the benefits that a well-trained human tutor provides to students, by interpreting student answers and appropriately responding in order to encourage elaboration. BRCA Gist is an ITS developed using AutoTutor Lite, a Web-based version of AutoTutor. Fuzzy-trace theory theoretically motivated the development of BRCA Gist, which engages people in tutorial dialogues to teach them about genetic breast cancer risk. We describe an empirical method to create tutorial dialogues and fine-tune the calibration of BRCA Gist's semantic processing engine without a team of computer scientists. We created five interactive dialogues centered on pedagogic questions such as "What should someone do if she receives a positive result for genetic risk of breast cancer?" This method involved an iterative refinement process of repeated testing with different texts and successively making adjustments to the tutor's expectations and settings in order to improve performance. The goal of this method was to enable BRCA Gist to interpret and respond to answers in a manner that best facilitated learning. We developed a method to analyze the efficacy of the tutor's dialogues. We found that BRCA Gist's assessment of participants' answers was highly correlated with the quality of the answers found by trained human judges using a reliable rubric. The dialogue quality between users and BRCA Gist predicted performance on a breast cancer risk knowledge test completed after exposure to the tutor. The appropriateness of BRCA Gist's feedback also predicted the quality of answers and breast cancer risk knowledge test scores.

    Recent attempts by large tobacco companies to represent themselves as socially responsible have been widely dismissed as image management. Existing research supports such claims by pointing to the failings and misleading nature of corporate social responsibility (CSR) initiatives. However, few studies have focused in depth on what tobacco companies hoped to achieve through CSR or reflected on the extent to which these ambitions have been realised. Iterative searching relating to CSR strategies was undertaken of internal British American Tobacco (BAT) documents, released through litigation in the US. Relevant documents (764) were indexed and qualitatively analysed. In the past decade, BAT has actively developed a wide-ranging CSR programme. Company documents indicate that one of the key aims of this programme was to help the company secure access to policymakers and, thereby, increase the company's chances of influencing policy decisions. Taking the UK as a case study, this paper demonstrates the way in which CSR can be used to renew and maintain dialogue with policymakers, even in ostensibly unreceptive political contexts. In practice, the impact of this political use of CSR is likely to be context specific; depending on factors such as policy élites' understanding of the credibility of companies as a reliable source of information. The findings suggest that tobacco company CSR strategies can enable access to and dialogue with policymakers and provide opportunities for issue definition. CSR should therefore be seen as a form of corporate political activity. This underlines the need for broad implementation of Article 5.3 of the Framework Convention on Tobacco Control. Measures are needed to ensure transparency of interactions between all parts of government and the tobacco industry and for policy makers to be made more aware of what companies hope to achieve through CSR.

  8. Experiments with a methodology to model the role of R and D expenditures in energy technology learning processes: first results

    International Nuclear Information System (INIS)

    Miketa, A.; Schrattenholzer, L.

    2004-01-01

    This paper presents the results of using a stylized optimization model of the global electricity supply system to analyze the optimal research and development (R and D) support for an energy technology. The model takes into account the dynamics of technological progress as described by a so-called two-factor learning curve (2FLC). The two factors are cumulative experience (''learning by doing'') and accumulated knowledge (''learning by searching''); the formulation is a straightforward expansion of conventional one-factor learning curves, in which only cumulative experience is included as a factor, which aggregates the effects of accumulated knowledge and cumulative experience, among others. The responsiveness of technological progress to the two factors is quantified using learning parameters, which are estimated using empirical data. Sensitivities of the model results to the parameters are also tested. The model results also address the effect of competition between technologies and of CO 2 constraints. The results are mainly methodological; one of the most interesting is that, at least up to a point, competition between technologies-in terms of both market share and R and D support-need not lead to ''lock-in'' or ''crowding-out''.

    Public engagement with science and technology is now widely used in science policy and communication. Touted as a means of enhancing democratic discussion of science and technology, analysis of public engagement with science and technology has shown that it is often weakly tied to scientific governance. In this article, we suggest that the notion of capacity building might be a way of reframing the democratic potential of public engagement with science and technology activities. Drawing on literatures from public policy and administration, we outline how public engagement with science and technology might build citizen capacity, before using the notion of capacity building to develop five principles for the design of public engagement with science and technology. We demonstrate the use of these principles through a discussion of the development and realization of the pilot for a large-scale public engagement with science and technology activity, the Futurescape City Tours, which was carried out in Arizona in 2012.

  16. The Teacher Technology Integration Experience: Practice and Reflection in the Classroom

    Directory of Open Access Journals (Sweden)

    Dana Ruggiero

    2015-05-01

    Full Text Available Previous studies indicated that the technology integration practices of teachers in the classroom often did not match their teaching styles. Researchers concluded that this was due, at least partially, to external barriers that prevented teachers from using technology in ways that matched their practiced teaching style. Many of these barriers, such as professional support and access to hardware and software, have been largely diminished over the last twenty years due to an influx of money and strategies for enhancing technology in primary and secondary schools in the United States. This mixed-methods research study was designed to examine the question, “What technology do teachers use and how do they use that technology to facilitate student learning?” K-12 classroom teachers were purposefully selected based on their full-time employment in a public, private, or religious school in a Midwestern state in the United States, supported by the endorsement of a school official. There were 1048 teachers from over 100 school corporations who completed an online survey consisting of six questions about classroom technology tools and professional development involving technology. Survey results suggest that technology integration is pervasive in the classroom with the most often used technology tool identified as PowerPoint. Moreover, teachers identified that training about technology is most effective when it is contextually based in their own classroom. Follow-up interviews were conducted with ten percent (n=111 of the teachers in order to examine the relationship between teachers’ daily classroom use of technology and their pedagogical practices. Results suggest a close relationship; for example, teachers with student-centric technology activities were supported by student-centric pedagogical practices in other areas. Moreover, teachers with strongly student-centered practices tended to exhibit a more pronounced need to create learning

    Sauerwein, Timothy A.; Gostomski, Thomas

    2008-01-01

    The ST5 technology demonstration mission led by GSFC of NASA's New Millennium Program managed by JPL consisted of three micro satellites (approximately 30 kg each) deployed into orbit from the Pegasus XL launch vehicle. In order to meet the launch date schedule of ST5, a different approach was required rather than the standard I&T approach used for single, room-sized satellites. The three spacecraft were designed, integrated, and tested at NASA Goddard Space Flight Center. It was determined that there was insufficient time in the schedule to perform three spacecraft I&T activities in series using standard approaches. The solution was for spacecraft #1 to undergo integration and test first, followed by spacecraft #2 and #3 simultaneously. This simultaneous integration was successful for several reasons. Each spacecraft had a Lead Test Conductor who planned and coordinated their spacecraft through its integration and test activities. One team of engineers and technicians executed the integration of all three spacecraft, learning and gaining knowledge and efficiency as spacecraft #1 integration and testing progressed. They became acutely familiar with the hardware, operation and processes for I&T, thus had the experience and knowledge to safely execute I&T for spacecraft #2 and #3. The integration team was extremely versatile; each member could perform many different activities or work any spacecraft, when needed. ST5 was successfully integrated, tested and shipped to the launch site per the I&T schedule that was planned three years previously. The I&T campaign was completed with ST5's successful launch on March 22, 2006.

  19. Analysis of diffusion paths for photovoltaic technology based on experience curves

    International Nuclear Information System (INIS)

    Poponi, Daniele

    2003-04-01

    This paper assesses the prospects for diffusion of photovoltaic (PV) technology for electricity generation in grid-connected systems. The analysis begins with the calculation of the break-even price of PV systems and modules, which is the price that can assure commercial viability without incentives or subsidies. The calculated average break-even price of PV systems for building-integrated applications is about US dollars 3.2/W p but can go up to about US dollars 4.5/W p in areas with very good solar irradiation and if a low real discount rate is applied. These are higher values than the break-even prices estimated in the literature to date. PV system break-even prices for intermediate load generation in utility-owned systems are also calculated, their average being about US dollars 1/W p The methodology of experience curves is used to predict what would be the different levels of cumulative world PV shipments required to reach the calculated break-even prices of PV systems, assuming different trends in the relationship between price and the increase in cumulative shipments. The years in which the break-even levels of cumulative shipments could be theoretically obtained are then calculated by considering different market growth rates. Photovoltaics could enter the niche of building-integrated applications without incentives in the first years of the next decade, provided that the PR is 80% and the average annual world market growth rate is at least 15%. The final part of the paper analyzes the niche markets or applications that seem promising for the diffusion of photovoltaics in the next few years (Author)

    O.I. OLADELE

    2010-09-01

    Full Text Available The development and dissemination of sawah rice eco-technology in Nigeria and Ghana as prerequisites for the actualization of green revolution in West Africa were described. It showed that the neglect of the eco-technology and the overemphasis of the biotechnology have rendered the ineffective transferability of the green revolution process from Asia to Africa. The sawah eco-technology increases yield up to 5 t/hm2 through bunding and the use of inlet and outlet connecting irrigation and drainage, which enhances effective water control and management, improves the efficiency of fertilizer, improves nitrogen fixation by soil microbes and algae, increases the use of wetlands, improves soil organic matter accumulation, suppresses weed growth, and enhances immune mechanism of rice through nutrient supply. The current experience has therefore established that the technology overcomes the constraints that have limited the realization of green revolution in West Africa.

    A 3-month-long, large-scale flume experiment involving research and testing of selected conventional and surrogate bedload-monitoring technologies was conducted in the Main Channel at the St. Anthony Falls Laboratory under the auspices of the National Center for Earth-surface Dynamics. These experiments, dubbed StreamLab06, involved 25 researchers and volunteers from academia, government, and the private sector. The research channel was equipped with a sediment-recirculation system and a sediment-flux monitoring system that allowed continuous measurement of sediment flux in the flume and provided a data set by which samplers were evaluated. Selected bedload-measurement technologies were tested under a range of flow and sediment-transport conditions. The experiment was conducted in two phases. The bed material in phase I was well-sorted siliceous sand (0.6-1.8 mm median diameter). A gravel mixture (1-32 mm median diameter) composed the bed material in phase II. Four conventional bedload samplers – a standard Helley-Smith, Elwha, BLH-84, and Toutle River II (TR-2) sampler – were manually deployed as part of both experiment phases. Bedload traps were deployed in study Phase II. Two surrogate bedload samplers – stationarymounted down-looking 600 kHz and 1200 kHz acoustic Doppler current profilers – were deployed in experiment phase II. This paper presents an overview of the experiment including the specific data-collection technologies used and the ambient hydraulic, sediment-transport and environmental conditions measured as part of the experiment. All data collected as part of the StreamLab06 experiments are, or will be available to the research community.

  12. Community Geothermal Technology Program: Cloth dyeing by geothermal steam. An experiment in technology transfer from Japan to Hawaii, Final report

    Energy Technology Data Exchange (ETDEWEB)

    Furumoto, A.S.

    1987-12-31

    This was an experiment to test whether cloth dyeing using geothermal steam (already proven in Japan) would be feasible in Hawaii. Results: Using a fabricated steam vat, cotton, silk, and synthetic can be dyed; the resulting material received high grades for steadfastness and permanency under dye testing. Techniques that were successful in Matsukawa, were replicated in Puna. However, attempts to embed leaf patterns on cloth using natural leaves and to extract natural dyes from Hawaiian plants were unsuccessful; the color of natural dyes deteriorated in hours. But chemical dyes gave brilliant hues or shades, in contrast to those in Japan where the steam there gave subdued tones. It is concluded that geothermal dyeing can be a viable cottage industry in Puna, Hawaii.

    The interRAI-Home Care (interRAI-HC) instrument is commonly used in routine care to assess care and service needs, resource utilisation and health outcomes of community dwelling home care clients. Potentially, the interRAI-HC can also be used to calculate societal costs in economic evaluations. The purpose of this study was to assess the convergent validity of the interRAI-HC instrument in comparison with the RUD Lite instrument for the calculation of societal costs among care-dependent community dwelling older adults. A within-subject design was used. Participants were 65 years and older and received professional community care in five countries. The RUD Lite was administered by trained (research) nurses or self-reports within 4 weeks after the interRAI-HC assessment. Agreement between the interRAI-HC and RUD Lite estimates was assessed using Spearman's correlation coefficients. We hypothesised that there was strong correlation (Spearman's ρ > 0.5) between resource utilisation estimates, costs of care estimates and total societal cost estimates derived from both instruments. Strong correlation was found between RUD Lite and interRAI-HC resource utilisation assessments for eight out of ten resource utilisation items. Total societal costs according to the RUD Lite were statistically significantly lower than according to the interRAI-HC (mean difference €-804, 95 % CI -1340; -269). The correlation between the instruments for total societal costs and all six cost categories was strong. The interRAI-HC has good convergent validity as compared with the RUD-Lite instrument to estimate societal cost of resource utilisation in community dwelling older adults. Since interRAI-HC assessments are part of routine care in many community care organisations and countries already, this finding may increase the feasibility of performing economic evaluations among community dwelling older adults.

    2010-02-01

    Abstract This paper explores the varied meanings and lived experiences of older people with dementia, in relation to everyday technologies in public spaces outside the home, through re-analysis of qualitative data generated from research that focused on the use of technology in supporting people with dementia to carry on with their everyday outside activities. The data have been re-analysed to critically examine how people with memory loss manage being outside in both familiar and unfamiliar public environments. In doing so the authors explore how technologies mediate between the physical and social environment in which people with dementia live. This paper highlights the importance of a neglected space within dementia research, namely the outside public environment. Although the outside environment and activities that take place in that space, for some, are curtailed, for others the physical and social security of familiar environments enables them to carry on with everyday activities in this public realm. Outside space can be both therapeutic and frightening and this paper demonstrates that people with dementia can sometimes feel out of place in public space. It however also shows the variety of ways people with dementia use everyday technologies to manage 'feeling out of place'.

    The results obtained show that it is possible to control light-weight robots with flexible links in a manner that produces good response time and does not induce unacceptable link vibrations. However, deflections induced by gravity cause large static position errors with such a control system. For this reason, it is not possible to use this control system for controlling motion in the direction of gravity. The control system does, on the other hand, have potential for use in space. However, in-space experiments will be needed to verify its applicability to robots moving in three dimensions.

    The applications of embedded system technologies have spread widely in various products, such as home appliances, cellular phones, automobiles, industrial machines and so on. Due to intensified competition, embedded software has expanded its role in realizing sophisticated functions, and new development methods like a hardware/software (HW/SW) co-design for uniting HW and SW development have been researched. The shortfall of embedded SW engineers was estimated to be approximately 99,000 in the year 2006, in Japan. Embedded SW engineers should understand HW technologies and system architecture design as well as SW technologies. However, a few universities offer this kind of education systematically. We propose a student experiment method for learning the basics of embedded system development, which includes a set of experiments for developing embedded SW, developing embedded HW and experiencing HW/SW co-design. The co-design experiment helps students learn about the basics of embedded system architecture design and the flow of designing actual HW and SW modules. We developed these experiments and evaluated them.

  13. Pennsylvania's technologically enhanced, naturally occurring radioactive material experiences and studies of the oil and gas industry.

    Allard, David J

    2015-02-01

    This presentation provides an overview of the Commonwealth of Pennsylvania's experiences and ongoing studies related to technologically enhanced, naturally occurring radioactive material (TENORM) in the oil and gas industry. It has been known for many years that Pennsylvania's geology is unique, with several areas having relatively high levels of natural uranium and thorium. In the 1950s, a few areas of the state were evaluated for commercial uranium production. In the late 1970s, scoping studies of radon in homes prompted the Pennsylvania Department of Environmental Protection (DEP) Bureau of Radiation Protection (BRP) to begin planning for a larger state-wide radon study. The BRP and Oil and Gas Bureau also performed a TENORM study of produced water in the early 1990s for a number of conventional oil and gas wells. More recently, BRP and the Bureau of Solid Waste developed radiation monitoring regulations for all Pennsylvania solid waste disposal facilities. These were implemented in 2001, prompting another evaluation of oil and gas operations and sludge generated from the treatment of conventionally produced water and brine but mainly focused on the disposal of TENORM solid waste in the state's Resource Conservation and Recovery Act Subtitle D landfills. However, since 2008, the increase in volumes of gas well wastewater and levels of Ra observed in the unconventional shale gas well flow-back fracking water has compelled DEP to fully re-examine these oil and gas operations. Specifically, with BRP in the lead, a new TENORM study of oil and gas operations and related wastewater treatment operations has been initiated (), supported by an American National Standards Institute standard on TENORM () and a U.S. Government Accountability Office report on shale resource development and risks (). This study began in early 2013 and will examine the potential public and worker radiation exposure and environmental impact as well as re-evaluate TENORM waste disposal. This

    The Monterey Coordinated Canyon Experiment (CCE) deployed an array of instruments along the Monterey Canyon floor to characterize the structure, velocity and frequency of sediment flows. CCE utilized novel technologies developed at MBARI to capture sediment flow data in unprecedented detail. 1. The Seafloor Instrument Node (SIN) at 1850 meters depth housed 3 ADCPs at 3 different frequencies, CTD, current meter, oxygen optode, fluorometer/backscatter sensor, and logged data at 10 second intervals or faster. The SIN included an acoustic modem for communication with shore through a Wave Glider relay, and provided high-resolution measurements of three flow events during three successive deployments over 1.5 years. 2. Beachball-sized Benthic Event Detectors (BEDs) were deployed on or under the seafloor to measure the characteristics of sediment density flows. Each BED recorded data from a pressure sensor and a 3-axis accelerometer and gyro to characterize motions during transport events (e.g. tumble vs rotation). An acoustic modem capable of operating through more than a meter of sediment enabled communications with a ship or autonomous surface vehicle. Multiple BEDs were deployed at various depths in the canyon during CCE, detecting and measuring many transport events; one BED moved 9 km down canyon in 50 minutes during one event. 3. Wave Glider Hot Spot (HS), equipped with acoustic and RF modems, acted as data relay between SIN, BEDs and shore, and acoustically located BEDs after sediment density flows.. In some cases HS relayed BED motion data to shore within a few hours of the event. HS provided an acoustic console to the SIN, allowing shore-based users to check SIN health and status, perform maintenance, etc. 4. Mapping operations were conducted 4 times at the SIN site to quantify depositional and erosional patterns, utilizing a prototype ultra-high-resolution mapping system on the ROV Doc Ricketts. The system consists of a 400-kHz Reson 7125 multibeam sonar, a 3

    The Synergy CircuLite micropump is a novel partial-support miniature left ventricular assist device that propels 2-3 l/min blood from the left atrium into the right subclavian artery. The ability of currently available investigative modalities to confirm Synergy pump malfunction is limited. The Synergy speed fluctuates periodically (at 10-s intervals) from the baseline to a transient decrease followed by a transient increase (alternating speed algorithm, ASA) with the purpose of changing the blood flow behaviour, thereby reducing thrombogenicity. The aim of this study was to develop a simple non-invasive monitoring technique to assess pump function based on the detection of the ASA in the peripheral microcirculation. Between February 2012 and July 2013, 10 patients with advanced chronic heart failure underwent Synergy implantation at our institution. The pump function was assessed by echocardiography and invasive monitoring according to standard protocols; additionally, the pump speed and power consumption were monitored. During the pump function assessment, the pulse oximeter waveform was recorded from the index fingers of the left and right hand with simultaneous pump auscultation using a stethoscope positioned on the pump (right infra-clavicular pocket). The pulse oximeter waveform was readily detectable from the right and left hand of all study patients. If the Synergy function was normal, there was a significant difference in the morphology of the pulse oximeter waveform from each hand: the ASA algorithm produced a more pronounced variation (giant wave) in the trace from the right hand than from the left. The giant waves invariably coincided with the sound variation associated with the ASA algorithms, which were detected regularly at 10-s intervals. We describe a simple, readily applicable, inexpensive, non-invasive technique that allows evaluation of Synergy pump function and may have diagnostic utility under conditions of suspected pump thrombus

A través de diferentes técnicas de análisis (escalamiento multidimensional, correlación y correlación parcial de matrices se puso a prueba si las distancias genéticas reflejaban las relaciones interpoblacionales esperadas a partir de la distribución geográfica o de relaciones lingüísticas entre las poblaciones. Además, se estimó en que grado las distintas medidas de distancias genéticas eran influenciadas por la diversidad (He de cada población. Los mapas genéticos muestran, principalmente para DST y DA, que las poblaciones aisladas y con bajo tamaño efectivo (Ne aparecen como outliers, mientras que las poblaciones con alto Ne y mayor flujo génico ocupan una posición central a bajos valores de distancia unas de otras y sin un patrón definido de agrupamiento. La falta de asociación entre distancias genéticas y lingüísticas o geográficas y por otra parte, la alta correlación negativa entre He y distancias génicas promedio por población confiman ese patrón, demostrando que la mayor parte de la variación interpoblacional puede ser explicada en función del grado de diversidad intrapoblacional. Es decir, las distancias genéticas no reflejan relaciones filogenéticas, lingüísticas o geográficas, sino más bien eventos demográficos recientes tales como cuellos de botella genético, efecto fundador o migración externa masiva. Este hecho puede ser comprobado por medio de otra metodología analítica, el modelo de Harpending y Ward.

  1. Interfacing Detectors and Collecting Data for Large-Scale Experiments in High Energy Physics Using COTS Technology

    CERN Document Server

    Schumacher, Jorn; Wandelli, Wainer

    Data-acquisition systems for high-energy physics experiments like the ATLAS experiment at the European particle-physics research institute CERN are used to record experimental physics data and are essential for the effective operation of an experiment. Located in underground facilities with limited space, power, cooling, and exposed to ionizing radiation and strong magnetic fields, data-acquisition systems have unique requirements and are challenging to design and build. Traditionally, these systems have been composed of custom-designed electronic components to be able to cope with the large data volumes that high-energy physics experiments generate and at the same time meet technological and environmental requirements. Custom-designed electronics is costly to develop, effortful to maintain and typically not very flexible. This thesis explores an alternative architecture for data-acquisition systems based on commercial off-the-shelf (COTS) components. A COTS-based data distribution device called FELIX that w...

    The UMLS Knowledge Source Server (UMLSKS), developed at the National Library of Medicine (NLM), makes the knowledge sources of the Unified Medical Language System (UMLS) available to the research community over the Internet. In 2003, the UMLSKS was redesigned utilizing state-of-the-art technologies available at that time. That design offered a significant improvement over the prior version but presented a set of technology-dependent issues that limited its functionality and usability. Four areas of desired improvement were identified: software interfaces, web interface content, system maintenance/deployment, and user authentication. By employing next generation web technologies, newer authentication paradigms and further refinements in modular design methods, these areas could be addressed and corrected to meet the ever increasing needs of UMLSKS developers. In this paper we detail the issues present with the existing system and describe the new system's design using new technologies considered entrants in the Web 2.0 development era.

    Full Text Available The United States Military Academy (USMA at West Point has the mission to produce officers for the U.S. Army. As part of the curriculum, the Academy requires all non-ABET major cadets (students to take two courses on information technology (IT with both courses focused on problem solving with technology. The first course is an introductory course offered in the freshman year while the second course is a more detailed course offered in the junior year. The Electrical Engineering and Computer Science Department uses an expanded definition of information technology; that is, any technology that acquires, transmits, processes, or displays information. Information technology is becoming increasingly important in the Army with the development and use of sensors, command and control systems, and other technologies to achieve information dominance. The course is divided into six modules: acquisition of data and sensors, transmission of data and networks, processing of data into information, display of information, legal and ethical issues of IT, and information dominance and operations. Cadets use a four-step problem solving methodology to develop and implement the components of an Information System to solve a real-world problem. The short-term impact of the course on the cadets has been very positive, and we are confident that the long-term impact will be substantial on the cadets and the Army. Cadets are exposed to a number of different technologies, gaining an understanding of how these technologies are used to acquire data, transmit data, process data into information, and display information to support decision making. In addition, the course projects help enforce the problem solving methodology where cadets analyze, design, implement, and test their solutions.

    In the advent of new technologies and knowledge, countries need to rely on one another for progress and development. At the same time, new challenges to development, which are beyond the competence of any country to approach individually, have emerged. These have led to greater need for international co-operation, particularly among the developing countries. In Malaysia, international technical co-operation has contributed significantly towards the development of nuclear technology. Malaysia has received technical assistance through the multilateral, regional and bilateral co-operation. This assistance complements the efforts of the government to meet the primary objectives of science and technology programme, which are; intensification of R and D capacity and applications of technologies, both acquired and developed, in national development. Over the last one and a half decade, more than 70 projects valued almost USD 15 millions, were implemented under the Technical Assistance Programme of the International Atomic Energy Agency and the Bilateral Technical Assistance Programme of Japan and Australia. Malaysia also has benefited from the regional technical co-operation programme such Regional Co-operative Agreement for Asia and Pacific Region, United Nation Department Programme, International Nuclear Co-operation in Asia. While receiving assistance, Malaysia continues to assist other developing countries in their development efforts in the fields of nuclear technology, through the various international co-operation programmes. This report reviews the technical assistance received through the international co-operation and its contributions towards the development of nuclear technology in Malaysia for period 1980 - 1996

    Full Text Available RFID technology has found a wide application in both civilian and military systems with very different purposes; moreover, a tremendous growth of its application is predicted in the future. As a support to core activities, both in the Army and business systems, logistics must provide the conditions for a continuous system optimization, which can be achieved by RFID technology. It provides data collecting, processing, automated identification and storage. The most important factors of logistics information systems are satisfied with this technology. The main feature of the logistics of controlling - that data is always to be collected at a source - is also present. Managing supply chains is almost inconceivable without modern information systems. This technology enables automated data processing thus creating conditions which facilitate decision making. Military applications of RFID technology include monitoring codified items to the extent required by competent commanders, as well as documenting changes in business processes within provided logistic functions of supply. This work gives an analytical approach to the methods of RFID technology application in foreign armies with regard to its possible introduction into the practice of the Serbian Army.

    Alternatives are being developed for waste treatment all over the world. Solidary selective collection is a recognized social technology for taking millions of people out of absolute poverty. However, this technology raises crucial questions regarding its nature and development perspective. What can be said of the legitimacy of a social technology that is born from misery and maintains wastepickers in precarious work conditions? This article approaches issues based on the analysis of the wastepickers' work process, highlighting the difficulties and interpersonal conflicts, the strong social bonds and creativity that reveal the potential of efficiency and solidarity of this social technology. The analyses are founded on empirical descriptions of work situations and organizational arrangements that the wastepickers themselves have developed. The observations were made during the work, followed by interviews focused on significant events and behaviors. The contradiction between efficiency and solidarity, which excludes workers from the formal labor market, finds in the associations a solution for people with different capacities. This social technology offers much more than simple survival or exoticism. The wastepickers create a sustainable mode of production, putting together economic, social and environmental criteria in an innovative and fair production technology.

    Schurr, M O; Arezzo, A; Buess, G F

    1999-11-01

    The advent of endoscopic techniques changed surgery in many regards. This paper intends to describe an overview about technologies to facilitate endoscopic surgery. The systems described have been developed for the use in general surgery, but an easy application also in the field of cardiac surgery seems realistic. The introduction of system technology and robotic technology enables today to design a highly ergonomic solo-surgery platform. To relief the surgeon from fatigue we developed a new chair dedicated to the functional needs of endoscopic surgery. The foot pedals for high frequency, suction and irrigation are integrated into the basis of the chair. The chair is driven by electric motors controlled with an additional foot pedal joystick to achieve the desired position in the OR. A major enhancement for endoscopic technology is the introduction of robotic technology to design assisting devices for solo-surgery and manipulators for microsurgical instrumentation. A further step in the employment of robotic technology is the design of 'master-slave manipulators' to provide the surgeon with additional degrees of freedom of instrumentation. In 1996 a first prototype of an endoscopic manipulator system. named ARTEMIS, could be used in experimental applications. The system consists of a user station (master) and an instrument station (slave). The surgeon sits at a console which integrates endoscopic monitors, communication facilities and two master devices to control the two slave arms which are mounted to the operating table. Clinical use of the system, however, will require further development in the area of slave mechanics and the control system. Finally the implementation of telecommunication technology in combination with robotic instruments will open new frontiers, such as teleconsulting, teleassistance and telemanipulation.

    2012-10-01

    Full Text Available For many decades, cathode ray tube (CRT monitors have been the dominant display technology in vision science. However, in recent years, most manufacturers stopped their CRT production lines, which enforces the application of alternative display technology in the field of vision science. Here, we analyze liquid crystal displays (LCDs and organic light-emitting diode (OLED monitors for their applicability in vision science experiments. Based on extensive measurements of their photometric output, we compare these technologies and contrast them with classical CRT monitors. Vision scientists aim to accurately present both static and dynamic stimuli on their display devices. As for the presentation of static stimuli, we demonstrate an increased accuracy for LCD and OLED devices compared to CRT monitors, because the former exhibit a higher degree of independence of neighboring pixels. As for dynamic presentations, both CRTs and OLEDs outperform LCD devices in terms of accuracy, because dynamic presentations on LCDs require a reorientation of the liquid crystal molecules, so that successive frames in time depend on each other. Together with widely unknown and uncontrolled technical artifacts, these properties of LCDs may impair visual experiments that require high temporal precision. Therefore, OLED monitors are more suitable for vision science experiments with respect to both their static and their temporal characteristics. However, for certain applications in visual neuroscience, the low duty cycle of some OLED devices may introduce frequencies to the photometric output which fall within the window of visibility of neurons in the visual cortex and therefore interfere with single unit recordings.

    Full Text Available Banks are the engines that drive the operations in the financial sector, money markets and growth of an economy. With the rapidly growing banking industry in India, frauds in banks are also increasing fast, and fraudsters have started using innovative methods. A questionnaire-based survey was conducted in 2013-14 among 345 bank employees to know their perception towards bank frauds, degree of their compliance level, and integration of technology to detect, control and prevent frauds. This study provides discussion of the attitudes, strategies, and the technology that bank specialists will need to combat frauds. Banks that can leverage advances in technology and analytics to improve fraud prevention will reduce their fraud losses. In 2015, the RBI introduced new mechanisms for banks to check loan frauds by taking pro-active steps by setting up a Central Fraud Registry, introduced the concept of Red Flagged Account, and Indian investigative agencies will soon start sharing their databases with banks.

    Full Text Available The number of individuals with dementia in Norway is more than 78,000, and, as in all other European countries, this figure is expected to rise over the coming decades. The Norwegian Health Directorate encourages municipalities to make use of ‘welfare technology’ in order to contribute to independent living and quality of life in older adults, to increase the quality of community health care, to save time when providing community health services and to reduce costs, e.g. admission to a nursing home. Introducing welfare technology to care recipients requires innovation on the part of the community health care service with regard to increasing the competency of the staff in the operation of the technologies, as well as in establishing an infrastructure for ‘digital communication’. Research has shown that access to assistive technology may support individuals with mild cognitive impairments, as well as in an early phase of dementia. However, it is crucial that the technology addresses an identified need, and that the device is tailored to the person’s preferences and context. Therefore, it is important to train health professionals to assess the user’s needs and preferences and to identify resources and limitations in the particular context. Alma’s House in Oslo is a demonstration site and education center for welfare technologies. The education program for the certification of Alma supervisors has become an important strategy in educating occupational therapists (OTs and nurses on how to assess user needs, identify appropriate technology and implement this into the care recipient’s home.

    Full Text Available This article aimed to answer how the use of computers and the Internet, directly and indirectly, has affected the time of teaching work and how these tool have determined the experience of teachers. Sources of research consisted of doctoral and master theses, as well as official documents that referring to these concepts and instruments. The survey instrument was developed as a form, using a software for the collection and analysis of data; for the assessment of the results we used the content analysis technique. The results show the relationship between time and experience under different cultural conventions that permeate the school, consolidating awareness under contradictions supported by the potential of new technologies in a condition of atrophying the experience to which the training process and the work of the teacher would tend to be reduced. The method is achieved from critical theory, especially the concepts of experience indicated by Adorno and Benjamin, ideology of technological rationality and industrial society, by Marcuse, and key concepts of dialectical materialism, such as alienated labor, commodity and machinery, from Marx.

    The testing of new technologies aboard the International Space Station (ISS) is facilitated through the use of a passive experiment container, or PEC, developed at the NASA Langley Research Center. The PEC is an aluminum suitcase approximately 2 ft square and 5 in. thick. Inside the PEC are mounted Materials International Space Station Experiment (MISSE) plates that contain the test articles. The PEC is carried to the ISS aboard the space shuttle or a Russian resupply vehicle, where astronauts attach it to a handrail on the outer surface of the ISS and deploy the PEC, which is to say the suitcase is opened 180 deg. Typically, the PEC is left in this position for approximately 1 year, at which point astronauts close the PEC and it is returned to Earth. In the past, the PECs have contained passive experiments, principally designed to characterize the durability of materials subjected to the ultraviolet radiation and atomic oxygen present at the ISS orbit. The MISSE5 experiment is intended to characterize state-of-art (SOA) and beyond photovoltaic technologies.

    2011-05-01

    Full Text Available This paper is innovating the theory of elités in the way it was configured by the Central and Eastern European thinking (researches and studies because it is focused on the way the changing of the electoral system influences the structure of political parliamentary elités. This study aims at revealing the connection between the electoral system and the structure of political élites, and it is based on two sociological researches that took place in the Romanian Parliament (Chamber of Deputies in two different chronological and political moments. The first chronological moment was in October 2008 and the second was in November 2009. The political moments are given by the presence of two different types of electoral systems. In the first research, the political élites analyzed belonged to a parliament elected by a proportional representation system (PR on closed lists, and in the second, the elections took place by „uninominal” system. It is shown that the change of electoral system from a period to another does determines the strategy of behavior of the political parliamentary élites and, implicitly, the functioning of parliamentary democracy through the political decisions that shape a certain behavior of élites.
