The Impact of Virtual Reality-based Learning Environment Design Features on Students' Academic Achievements  

E-Print Network (OSTI)

Virtual reality-based instruction such as virtual worlds, games, and simulations are becoming very popular in K-12 and higher education. Three manuscripts that report the results of investigations of these increasingly prevalent instructional media were developed for this dissertation. The purpose of the first study, a meta-analysis, was to analyze the instructional effectiveness of virtual reality-based instruction when compared to the traditional methods of instruction. In addition, this study also explored selected instructional design features of the virtual learning environment that moderated the relationship between instructional method and the academic achievements. Analyses of 63 experimental or quasi-experimental studies that studied learning outcomes of virtual reality-based instruction in K-12 or higher education settings yielded a mean effect size of g = 0.47 (SE = 0.02) suggesting that virtual reality-based instruction is an effective medium of delivering instruction. Further analyses examined factors that influence its effectiveness. The purpose of the second study was to examine a model of the impact of a 3-D desktop virtual reality environment on the learner characteristics (i.e. perceptual and psychological variables) that can enhance chemistry-related learning achievements in an introductory college chemistry class. A theoretical model of the relationships of features of 3-D virtual reality environments and students' experiences in the environments to outcomes on a chemistry learning test and measures of spatial ability and self-efficacy was tested using structural equation modeling. Usability strongly mediated the relationship between 3-D virtual reality features, spatial orientation, self-efficacy, and presence. Spatial orientation and self-efficacy had a statistically significant, positive impact on the chemistry learning test. The purpose of the third study was to investigate the potential of Second Life (SL), a 3-D virtual world, to enhance undergraduate students? learning of a foundational chemistry concept, spatial ability, and self-efficacy. A quasi-experimental pretest-posttest control group design was used. A total of 387 participants completed three assignment activities either in Second Life or using 2-D images. The difference between the scores of 3-D virtual environment-based group and the 2-D images-based group was not statistically significant for any of the measures.

Women negotiating collaborative learning: an exploratory study of undergraduate students in a select university setting  

E-Print Network (OSTI)

The purpose of the study is to explore women's experiences as they negotiate collaborative group projects in a college course. This qualitative study extends the existing literature by providing depth to the research on women's learning through observation of women in group activities, surveys about college students' attitudes toward collaborative learning, and in-depth interviews with university women. The study isolates four ways women negotiate collaborative learning in a college course. (1) Women take group work seriously and consider it to be very important. (2) Women are often leaders in group work. Sixty-four percent of the women and only two percent of the men said they are usually the leader in collaborative learning situations. (3) Women end up doing more than their share of the work, although they may have won the leadership roles. (4) Earning good grades is very important to the women studied, and they are willing to work harder than anyone else in a group to earn them. The theories of how women learn include the debate over whether women are relational or task-oriented. The conclusion of this study is that in the university classes studied, women are both. However, textbooks on collaborative learning may contain passages that indicate that in mixed-sex groups males will emerge as leaders. In addition, some textbooks suggest that women might lead when groups are primarily dealing with relationship issues, and men will lead when groups are primarily task-oriented or where a democratic rather than a participatory style is preferred. Discussions of collaborative learning often include the goal of helping counterweigh the hidden curriculum that diminishes women. Although collaborative learning can be an important classroom technique, this study points out that it is important that collaborative learning and feminist pedagogy not be conflated. Some collaborative learning groups are a site of discrimination and power difference for women.

Going to the End of the Earth to Learn About the Beginning of the Universe  

SciTech Connect

The cosmic microwave background (CMB) is revolutionizing our understanding of the Universe. The CMB is the most powerful piece of evidence that we live in a geometrically flat Universe, dominated by cold dark matter and dark energy. Even with this basic cosmological model established, there are still many outstanding questions: What is dark energy? What is the sum of the neutrino masses? Are there unknown particle species that we can detect cosmologically? Did Inflation happen? I will review the history of measurements of the CMB; what have they told us so far, and how the South Pole has developed into the premier site for observations of the CMB. Finally, I will discuss new measurements and cosmological results from the South Pole Telescope, a 10-meter diameter telescope that is making precision measurements of the temperature and polarization anisotropy of the CMB.

Virtual Laboratories  

E-Print Network (OSTI)

At the frontier of most areas in science, computer simulations play a central role. The traditional division of natural science into experimental and theoretical investigations is now completely outdated. Instead, theory, simulation, and experimentation form three equally essential aspects, each with its own unique flavor and challenges. Yet, education in computational science is still lagging far behind, and the number of text books in this area is minuscule compared to the many text books on theoretical and experimental science. As a result, many researchers still carry out simulations in a haphazard way, without properly setting up the computational equivalent of a well equipped laboratory. The art of creating such a virtual laboratory, while providing proper extensibility and documentation, is still in its infancy. A new approach is described here, Open Knowledge, as an extension of the notion of Open Source software. Besides open source code, manuals, and primers, an open knowledge project provides simulated dialogues between code developers, thus sharing not only the code, but also the motivations behind the code.

DOE Patents (OSTI)

An apparatus and method of issuing commands to a computer by a user interfacing with a virtual reality environment are disclosed. To issue a command, the user directs gaze at a virtual button within the virtual reality environment, causing a perceptible change in the virtual button, which then sends a command corresponding to the virtual button to the computer, optionally after a confirming action is performed by the user, such as depressing a thumb switch. 4 figs.

Virtual PCR  

Science Conference Proceedings (OSTI)

The polymerase chain reaction (PCR) stands among the keystone technologies for analysis of biological sequence data. PCR is used to amplify DNA, to generate many copies from as little as a single template. This is essential, for example, in processing forensic DNA samples, pathogen detection in clinical or biothreat surveillance applications, and medical genotyping for diagnosis and treatment of disease. It is used in virtually every laboratory doing molecular, cellular, genetic, ecologic, forensic, or medical research. Despite its ubiquity, we lack the precise predictive capability that would enable detailed optimization of PCR reaction dynamics. In this LDRD, we proposed to develop Virtual PCR (VPCR) software, a computational method to model the kinetic, thermodynamic, and biological processes of PCR reactions. Given a successful completion, these tools will allow us to predict both the sequences and concentrations of all species that are amplified during PCR. The ability to answer the following questions will allow us both to optimize the PCR process and interpret the PCR results: What products are amplified when sequence mixtures are present, containing multiple, closely related targets and multiplexed primers, which may hybridize with sequence mismatches? What are the effects of time, temperature, and DNA concentrations on the concentrations of products? A better understanding of these issues will improve the design and interpretation of PCR reactions. The status of the VPCR project after 1.5 years of funding is consistent with the goals of the overall project which was scoped for 3 years of funding. At half way through the projected timeline of the project we have an early beta version of the VPCR code. We have begun investigating means to improve the robustness of the code, performed preliminary experiments to test the code and begun drafting manuscripts for publication. Although an experimental protocol for testing the code was developed, the preliminary experiments were tainted by contaminated products received from the manufacturer. Much knowledge has been gained in the development of the code thus far, but without final debugging, increasing its robustness and verifying it against experimental results, the papers which we have drafted to share our findings still require the final data necessary for publication. The following sections summarize our final progress on VPCR as it stands after 1.5 years of effort on an ambitious project scoped for a 3 year period. We have additional details of the methods than are provided here, but would like to have legal protection in place before releasing them. The result of this project, a suite of programs that predict PCR products as a function of reaction conditions and sequences, will be used to address outstanding questions in pathogen detection and forensics at LLNL. VPCR should enable scientists to optimize PCR protocols in terms of time, temperature, ion concentration, and primer sequences and concentrations, and to estimate products and error rates in advance of performing experiments. Our proposed capabilities are well ahead of all currently available technologies, which do not model non-equilibrium kinetics, polymerase extension, or predict multiple or undesired PCR products. We are currently seeking DHS funding to complete the project, at which time licensing opportunities will be explored, an updated patent application will be prepared, and a publication will be submitted. A provisional and a full patent application have already been filed (1).

Transportation planning: A virtual reality  

SciTech Connect

An important factor in the development of any base technology is generating it in such a way that these technologies will continue to be useful through systems upgrades and implementation philosophy metamorphoses. Base technologies of traffic engineering including transportation modeling, traffic impact forecasting, traffic operation management, emergency situation routing and re-routing, and signal systems optimization should all be designed with the future in mind. Advanced Traffic Engineering topics, such as Intelligent Vehicle Highway Systems, are designed with advanced engineering concepts such as rules-based design and artificial intelligence. All aspects of development of base technologies must include Total Quality Engineering as the primary factor in order to succeed. This philosophy for development of base technologies for the County of Los Alamos is being developed leveraging the resources of the Center for Advanced Engineering Technology (CAET) at the Los Alamos National Laboratory. The mission of the CAET is to develop next-generation engineering technology that supports the Los Alamos National Laboratory`s mission and to transfer that technology to industry and academia. The CAET`s goal is to promote industrial, academic, and government interactions in diverse areas of engineering technology, such as, design, analysis, manufacturing, virtual enterprise, robotics, telepresence, rapid prototyping, and virtual environment technology. The Center is expanding, enhancing, and increasing core competencies at the Los Alamos National Laboratory. The CAET has three major thrust areas: development of base technologies, virtual environment technology applications, and educational outreach and training. Virtual environment technology immerses a user in a nonexistent or augmented environment for research or training purposes. Virtual environment technology illustrates the axiom, ``The best way to learn is by doing.``

High availability using virtualization  

E-Print Network (OSTI)

High availability has always been one of the main problems for a data center. Till now high availability was achieved by host per host redundancy, a highly expensive method in terms of hardware and human costs. A new approach to the problem can be offered by virtualization. Using virtualization, it is possible to achieve a redundancy system for all the services running on a data center. This new approach to high availability allows to share the running virtual machines over the servers up and running, by exploiting the features of the virtualization layer: start, stop and move virtual machines between physical hosts. The system (3RC) is based on a finite state machine with hysteresis, providing the possibility to restart each virtual machine over any physical host, or reinstall it from scratch. A complete infrastructure has been developed to install operating system and middleware in a few minutes. To virtualize the main servers of a data center, a new procedure has been developed to migrate physical to virtu...

E-Print Network (OSTI)

The levels of immersion and presence felt by users in a Virtual Environment (VE) are very important factors that dictate the quality of the Virtual Reality (VR) experience. Sensori-motor systems, both hardware and software, are the components of a VR system that contribute to generate the VEs and to create the feeling of being there. This paper reviews the different visualization hardware/software components that are at the heart of a VR system and provides means for assessing their performance in the context of various applications. Because of its historical and functional importance in the field of VR, visualization hardware is reviewed first (HMDs, VRDs, stereo glasses, CRT, LCD monitors and Plasma displays...). Then, a list of the most important insights, which should be addressed when designing and assembling a VR system, are discussed. Finally, visualization software is covered in the context of the available hardware components.

Recent Developments in Virtual Reality Based Education  

E-Print Network (OSTI)

A series of virtual reality based educational modules are being developed to explore the capabilities of this emerging technology, and to determine how and where virtual reality can provide the greatest benefits to engineering educators. The most advanced application, Vicher, has been significantly expanded and split into two modules. Student evaluations of a newly developed safety analysis module show great promise, but also the need for further development. Other modules being developed cover topics in atomic crystal structures, fluid flow characteristics, thermodynamic relationships, and four component azeotropic distillation. This paper will describe the latest developments in the ongoing investigation of virtual reality as an educational medium. INTRODUCTION AND BACKGROUND Engineering educators are making use of an increasing number of computer simulation packages to aid them in attaining their educational objectives 5,7,9,10. The reasons for doing so include the desire to reach students that have alternate learning styles 4,11, to provide experience based education 6, and to augment traditional laboratory facilities that are being stretched increasingly thin with growing enrollments 3.

Virtual Human Problem Solving Environments  

SciTech Connect

Abstract. Interest in complex integrated digital or virtual human modeling has seen a significant increase over the last decade. Coincident with that increased interest, Oak Ridge National Laboratory (ORNL) initiated the development of a human simulation tool, the Virtual Human. The Virtual Human includes a problem-solving environment (PSE) for implementing the integration of physiological models in different programming languages and connecting physiological function to anatomy. The Virtual Human PSE (VHPSE) provides the computational framework with which to develop the concept of a "Virtual Human." Supporting the framework is a data definition for modeling parameters, PhysioML, a Virtual Human Database (VHDB), and a Web-based graphical user interface (GUI) developed using Java. Following description of the VHPSE, we discuss four example implementations of models within the framework. Further expansion of a human modeling environment was carried out in the Defense Advanced Research Projects Agency Virtual Soldier Project. SCIRun served as the Virtual Soldier problem solving environment (VSPSE). We review and compare specific developments in these projects that have significant potential for the future of Virtual Human modeling and simulation. We conclude with an evaluation of areas of future work that will provide important extensions to the VHPSE and VSPSE and make possible a fully-integrated environment for human anatomical and physiological modeling: the Virtual Human.

El principio de incerteza de Heisenberg: En 1927, Heisenberg enunció una propiedad fundamental de la mecánica cuántica que dice que es imposible medir EN FORMA EXACTA AMBOS, la posición de una partícula y su ímpetu. Cuanto mayor sea la precisión con que determinamos una, menos sabremos de la otra. Este es el llamado Principio de incerteza de Heisenberg. La relación matemática que lo expresa es: Significa que la incertidumbre en la posición (x), multiplicada por la incertidumbre en el momento (p), es mayor o igual que una constante (h-barra dividido por dos.) Este principio puede también ser escrito en términos de energía y tiempo: Significa que la incertidumbre en la energía de una partícula

Virtual Optical Comparator  

SciTech Connect

The Virtual Optical Comparator, VOC, was conceived as a result of the limitations of conventional optical comparators and vision systems. Piece part designs for mechanisms have started to include precision features on the face of parts that must be viewed using a reflected image rather than a profile shadow. The VOC concept uses a computer generated overlay and a digital camera to measure features on a video screen. The advantage of this system is superior edge detection compared to traditional systems. No vinyl charts are procured or inspected. The part size and expensive fixtures are no longer a concern because of the range of the X-Y table of the Virtual Optical Comparator. Product redesigns require only changes to the CAD image overlays; new vinyl charts are not required. The inspection process is more ergonomic by allowing the operator to view the part sitting at a desk rather than standing over a 30 inch screen. The procurement cost for the VOC will be less than a traditional comparator with a much smaller footprint with less maintenance and energy requirements.

Primitive Virtual Negative Charge  

E-Print Network (OSTI)

Physical fields, such as gravity and electromagnetic field, are interpreted as results from rearrangement of vacuum particles to get the equilibrium of net charge density and net mass density in 4-dimensional complex space. Then, both fields should interact to each other in that physical interaction is considered as a field-to-field interaction. Hence, Mass-Charge interaction is introduced with primitive-virtual negative charge defined for the mass. With the concept of Mass-Charge interaction electric equilibrium of the earth is discussed, especially about the electric field and magnetic field of the earth. For unsettled phenomena related with the earth's gravity, such as antigravity phenomenon, gravity anomalies during the solar eclipses, the connection between geomagnetic storms and earthquakes, etc., possible explanations are discussed.

VR/IS Lab Virtual Actor research overview  

SciTech Connect

This overview presents current research at Sandia National Laboratories in the Virtual Reality and Intelligent Simulation Lab. Into an existing distributed VR environment which we have been developing, and which provides shared immersion for multiple users, we are adding virtual actor support. The virtual actor support we are adding to this environment is intended to provide semi-autonomous actors, with oversight and high-level guiding control by a director/user, and to allow the overall action to be driven by a scenario. We present an overview of the environment into which our virtual actors will be added in Section 3, and discuss the direction of the Virtual Actor research itself in Section 4. We will briefly review related work in Section 2. First however we need to place the research in the context of what motivates it. The motivation for our construction of this environment, and the line of research associated with it, is based on a long-term program of providing support, through simulation, for situational training, by which we mean a type of training in which students learn to handle multiple situations or scenarios. In these situations, the student may encounter events ranging from the routine occurance to the rare emergency. Indeed, the appeal of such training systems is that they could allow the student to experience and develop effective responses for situations they would otherwise have no opportunity to practice, until they happened to encounter an actual occurance. Examples of the type of students for this kind of training would be security forces or emergency response forces. An example of the type of training scenario we would like to support is given in Section 4.2.

Advanced virtual energy simulation training and research: IGCC with CO2 capture power plant  

SciTech Connect

In this presentation, we highlight the deployment of a real-time dynamic simulator of an integrated gasification combined cycle (IGCC) power plant with CO{sub 2} capture at the Department of Energy's (DOE) National Energy Technology Laboratory's (NETL) Advanced Virtual Energy Simulation Training and Research (AVESTARTM) Center. The Center was established as part of the DOE's accelerating initiative to advance new clean coal technology for power generation. IGCC systems are an attractive technology option, generating low-cost electricity by converting coal and/or other fuels into a clean synthesis gas mixture in a process that is efficient and environmentally superior to conventional power plants. The IGCC dynamic simulator builds on, and reaches beyond, conventional power plant simulators to merge, for the first time, a 'gasification with CO{sub 2} capture' process simulator with a 'combined-cycle' power simulator. Fueled with coal, petroleum coke, and/or biomass, the gasification island of the simulated IGCC plant consists of two oxygen-blown, downward-fired, entrained-flow, slagging gasifiers with radiant syngas coolers and two-stage sour shift reactors, followed by a dual-stage acid gas removal process for CO{sub 2} capture. The combined cycle island consists of two F-class gas turbines, steam turbine, and a heat recovery steam generator with three-pressure levels. The dynamic simulator can be used for normal base-load operation, as well as plant start-up and shut down. The real-time dynamic simulator also responds satisfactorily to process disturbances, feedstock blending and switchovers, fluctuations in ambient conditions, and power demand load shedding. In addition, the full-scope simulator handles a wide range of abnormal situations, including equipment malfunctions and failures, together with changes initiated through actions from plant field operators. By providing a comprehensive IGCC operator training system, the AVESTAR Center is poised to develop a workforce well-prepared to operate and control commercial-scale gasification-based power plants capable of 90% pre-combustion CO{sub 2} capture and compression, as well as low sulfur, mercury, and NOx emissions. With additional support from the NETL-Regional University Alliance (NETL-RUA), the Center will educate and train engineering students and researchers by providing hands-on 'learning by operating' experience The AVESTAR Center also offers unique collaborative R&D opportunities in high-fidelity dynamic modeling, advanced process control, real-time optimization, and virtual plant simulation. Objectives and goals are aimed at safe and effective management of power generation systems for optimal efficiency, while protecting the environment. To add another dimension of realism to the AVESTAR experience, NETL will introduce an immersive training system with innovative three-dimensional virtual reality technology. Wearing a stereoscopic headset or eyewear, trainees will enter an interactive virtual environment that will allow them to move freely throughout the simulated 3-D facility to study and learn various aspects of IGCC plant operation, control, and safety. Such combined operator and immersive training systems go beyond traditional simulation and include more realistic scenarios, improved communication, and collaboration among co-workers.

Pipeline morphing is a simple but effectivetechnique for reconfiguring pipelined FPGA designs at run time. By overlapping computation and reconfiguration, the latency associated with emptying and refilling a pipeline can be avoided. Weshowhow morphing can be applied to linear and mesh pipelines at both word-level and bit-level, and explain how this method can be implemented using Xilinx 6200 FPGAs. We also present an approach using morphing to map a large virtual pipeline onto a small physical pipeline, and the trade-offs involved are discussed.

The Idaho National Laboratory (INL) in collaboration with the U.S. Geological Survey (USGS) virtually assessed the gross power potential of all natural streams in the United States of America and identified feasible potential project sites and estimated their developable power potential. The results of this virtual prospecting have been incorporated into a GIS application called the Virtual Hydropower Prospector that is available for public use on the Internet.

Virtually simulating the next generation of clean energy technologies: NETL's AVESTAR Center is dedicated to the safe, reliable and efficient operation of advanced energy plants with carbon capture  

SciTech Connect

Imagine using a real-time virtual simulator to learn to fly a space shuttle or rebuild your car's transmission without touching a piece of equipment or getting your hands dirty. Now, apply this concept to learning how to operate and control a state-of-the-art, electricity-producing power plant capable of carbon dioxide (CO{sub 2}) capture. That's what the National Energy Technology Laboratory's (NETL) Advanced Virtual Energy Simulation Training and Research (AVESTAR) Center (www.netl.doe.gov/avestar) is designed to do. Established as part of the Department of Energy's (DOE) initiative to advance new clean energy technology for power generation, the AVESTAR Center focuses primarily on providing simulation-based training for process engineers and energy plant operators, starting with the deployment of a first-of-a-kind operator training simulator for an integrated gasification combined cycle (IGCC) power plant with CO{sub 2} capture. The IGCC dynamic simulator builds on, and reaches beyond, conventional power plant simulators to merge, for the first time, a 'gasification with CO{sub 2} capture' process simulator with a 'combined-cycle' power simulator. Based on Invensys Operations Management's SimSci-Esscor DYNSIM software, the high-fidelity dynamic simulator provides realistic training on IGCC plant operations, including normal and faulted operations, as well as plant start-up, shutdown and power demand load changes. The highly flexible simulator also allows for testing of different types of fuel sources, such as petcoke and biomass, as well as co-firing fuel mixtures. The IGCC dynamic simulator is available at AVESTAR's two locations, NETL (Figure 1) and West Virginia University's National Research Center for Coal and Energy (www.nrcce.wvu.edu), both in Morgantown, W.Va. By offering a comprehensive IGCC training program, AVESTAR aims to develop a workforce well prepared to operate, control and manage commercial-scale gasification-based power plants with CO{sub 2} capture. The facility and simulator at West Virginia University promotes NETL's outreach mission by offering hands-on simulator training and education to researchers and university students.

High availability using virtualization - 3RC  

E-Print Network (OSTI)

High availability has always been one of the main problems for a data center. Till now high availability was achieved by host per host redundancy, a highly expensive method in terms of hardware and human costs. A new approach to the problem can be offered by virtualization. Using virtualization, it is possible to achieve a redundancy system for all the services running on a data center. This new approach to high availability allows the running virtual machines to be distributed over a small number of servers, by exploiting the features of the virtualization layer: start, stop and move virtual machines between physical hosts. The 3RC system is based on a finite state machine, providing the possibility to restart each virtual machine over any physical host, or reinstall it from scratch. A complete infrastructure has been developed to install operating system and middleware in a few minutes. To virtualize the main servers of a data center, a new procedure has been developed to migrate physical to virtual hosts. ...

Information, learning and falsification  

E-Print Network (OSTI)

Broadly speaking, there are two approaches to quantifying information. The first, Shannon information, takes events as belonging to ensembles and quantifies the information resulting from observing the given event in terms of the number of alternate events that have been ruled out. The second, algorithmic information or Kolmogorov complexity, takes events as strings and, given a universal Turing machine, quantifies the information content of a string as the length of the shortest program producing it. This note describes a new method of quantifying information, effective information, that links algorithmic information to Shannon information, and also links both to capacities arising in statistical learning theory. After introducing the measure, we show that it provides a non-universal analog of algorithmic information. We then apply it to derive basic capacities in statistical learning theory: empirical VC-entropy and empirical Rademacher complexity. A nice byproduct of our approach is an interpretation of th...

Kitten is an OS under development at Sandia that implements a lightweight kernel architecture to provide predictable behavior and increased flexibility on large machines, while also providing Linux binary compatibility. Palacios is a VMM that is under development at Northwestern University and the University of New Mexico. Palacios, which can be embedded into Kitten and other OSes, supports existing, unmodified applications and operating systems by using virtualization that leverages hardware technologies. We describe the design and implementation of both Kitten and Palacios. Our benchmarks show that they provide near native, scalable performance. Palacios and Kitten provide an incremental path to using supercomputer resources that is not performance-compromised.

Home-based Shared Virtual Memory  

E-Print Network (OSTI)

In this dissertation, I investigate how to improve the performance of shared virtual memory (SVM) by examining consistency models, protocols, hardware support and applications. The main conclusion of this research is that the performance of shared virtual memory can be significantly improved when performance-enhancing techniques from all these areas are combined. This dissertation proposes home-based lazy release consistency as a simple, effective, and scalable way to build shared virtual memory systems. In home-based protocols each shared page has a home to which all writes are propagated and from which all copies are derived. Two home-based protocols are described, implemented and evaluated on two hardware and software platforms: Automatic Update Release Consistency (AURC), which requires hardware support for fine-grained remote writes (automatic updates), and Homebased Lazy Release Consistency (HLRC), which is implemented exclusively in software. The dissertation investigates the ...

Virtual radiation fields for ALARA determination  

SciTech Connect

As computing power has increased, so too has the ability to model and simulate complex systems and processes. In addition, virtual reality technology has made it possible to visualize and understand many complex scientific and engineering problems. For this reason, a virtual dosimetry program called Virtual Radiation Fields (VRF) is developed to model radiation dose rate and cumulative dose to a receptor operating in a virtual radiation environment. With the design and testing of many facilities and products taking place in the virtual world, this program facilitates the concurrent consideration of radiological concerns during the design process. Three-dimensional (3D) graphical presentation of the radiation environment is made possible through the use of IGRIP, a graphical modeling program developed by Deneb Robotics, Inc. The VRF simulation program was designed to model and display a virtual dosimeter. As a demonstration of the program`s capability, the Hanford tank, C-106, was modeled to predict radiation doses to robotic equipment used to remove radioactive waste from the tank. To validate VRF dose predictions, comparison was made with reported values for tank C-106, which showed agreement to within 0.5%. Graphical information is presented regarding the 3D dose rate variation inside the tank. Cumulative dose predictions were made for the cleanup operations of tank C-106. A four-dimensional dose rate map generated by VRF was used to model the dose rate not only in 3D space but also as a function of the amount of waste remaining in the tank. This allowed VRF to predict dose rate at any stage in the waste removal process for an accurate simulation of the radiological conditions throughout the tank cleanup procedure.

Some aspects of virtual black holes  

SciTech Connect

We first consider consistently third-quantize modified gravity. We then analyze certain aspects of virtual black holes in this third-quantized modified gravity. We see how a statistical mechanical origin for the Bekenstein-Hawking entropy naturally arises in this model. Furthermore, the area and hence the entropy of a real macroscopic black hole is quantized in this model. Virtual black holes cause a loss of quantum coherence, which gives an intrinsic entropy to all physical systems that can be used to define a direction of time and hence provide a solution to the problem of time.

Ion mobility spectrometer with virtual aperture grid  

DOE Patents (OSTI)

An ion mobility spectrometer does not require a physical aperture grid to prevent premature ion detector response. The last electrodes adjacent to the ion collector (typically the last four or five) have an electrode pitch that is less than the width of the ion swarm and each of the adjacent electrodes is connected to a source of free charge, thereby providing a virtual aperture grid at the end of the drift region that shields the ion collector from the mirror current of the approaching ion swarm. The virtual aperture grid is less complex in assembly and function and is less sensitive to vibrations than the physical aperture grid.

Toward a virtual building laboratory  

SciTech Connect

In order to achieve in a timely manner the large energy and dollar savings technically possible through improvements in building energy efficiency, it will be necessary to solve the problem of design failure risk. The most economical method of doing this would be to learn to calculate building performance with sufficient detail, accuracy and reliability to avoid design failure. Existing building simulation models (BSM) are a large step in this direction, but are still not capable of this level of modeling. Developments in computational fluid dynamics (CFD) techniques now allow one to construct a road map from present BSM's to a complete building physical model. The most useful first step is a building interior model (BIM) that would allow prediction of local conditions affecting occupant health and comfort. To provide reliable prediction a BIM must incorporate the correct physical boundary conditions on a building interior. Doing so raises a number of specific technical problems and research questions. The solution of these within a context useful for building research and design is not likely to result from other research on CFD, which is directed toward the solution of different types of problems. A six-step plan for incorporating the correct boundary conditions within the context of the model problem of a large atrium has been outlined. A promising strategy for constructing a BIM is the overset grid technique for representing a building space in a CFD calculation. This technique promises to adapt well to building design and allows a step-by-step approach. A state-of-the-art CFD computer code using this technique has been adapted to the problem and can form the departure point for this research.

The Universe Adventure - The Modern Universe  

NLE Websites -- All DOE Office Websites (Extended Search)

Modern Universe Modern Universe Like astronomers throughout history, modern cosmologists are interested in making an accurate model of the Universe. Starting with the laws of physics which explain how fundamental particles and forces interact, physicists derive general equations describing the evolution of the Universe's structure. Cosmologists use experimental evidence to select a set of initial conditions enabling them to solve the general equations, and calculate the state of the Universe at times in the past, present, or future. This generates a possible model, which can be tested by comparing the phenomena it predicts with observational data. In this manner, following the rigorous scientific method, cosmologists work to build a successful Universal model. In the next section we will examine evidence for the current Big Bang

A Virtual Engineering Framework for Simulating Advanced Power System  

SciTech Connect

In this report is described the work effort performed to provide NETL with VE-Suite based Virtual Engineering software and enhanced equipment models to support NETL's Advanced Process Engineering Co-simulation (APECS) framework for advanced power generation systems. Enhancements to the software framework facilitated an important link between APECS and the virtual engineering capabilities provided by VE-Suite (e.g., equipment and process visualization, information assimilation). Model enhancements focused on improving predictions for the performance of entrained flow coal gasifiers and important auxiliary equipment (e.g., Air Separation Units) used in coal gasification systems. In addition, a Reduced Order Model generation tool and software to provide a coupling between APECS/AspenPlus and the GE GateCycle simulation system were developed. CAPE-Open model interfaces were employed where needed. The improved simulation capability is demonstrated on selected test problems. As part of the project an Advisory Panel was formed to provide guidance on the issues on which to focus the work effort. The Advisory Panel included experts from industry and academics in gasification, CO2 capture issues, process simulation and representatives from technology developers and the electric utility industry. To optimize the benefit to NETL, REI coordinated its efforts with NETL and NETL funded projects at Iowa State University, Carnegie Mellon University and ANSYS/Fluent, Inc. The improved simulation capabilities incorporated into APECS will enable researchers and engineers to better understand the interactions of different equipment components, identify weaknesses and processes needing improvement and thereby allow more efficient, less expensive plants to be developed and brought on-line faster and in a more cost-effective manner. These enhancements to APECS represent an important step toward having a fully integrated environment for performing plant simulation and engineering. Furthermore, with little effort the modeling capabilities described in this report can be extended to support other DOE programs, such as ultra super critical boiler development, oxy-combustion boiler development or modifications to existing plants to include CO2 capture and sequestration.

Integrating High Performance Computing and Virtual Environments  

E-Print Network (OSTI)

High performance computing has become accepted as a tool that can be used to solve many large scale computational problems. Because of the complexity of the problems associated with high performance computing, visualization of the output of high performance computing applications has always been an important factor in providing a complete problem solving environment for the high performance computing user. As visualization technology advances, it is important to consider what impacts those advances will have on the integration of high performance computing and visualization. Virtual environments are the most recent, and arguably the most powerful, visualization environments in use today. In this paper we analyze the current state of the research of integrating visualization, and in particular virtual environments, with high performance computing. We also present a framework for implementing such an environment and report on the status of its implementation at the Australian National Un...

Virtual Appliances for Deploying and Maintaining Software  

E-Print Network (OSTI)

This paper attempts to address the complexity of system administration by making the labor of applying software updates independent of the number of computers on which the software is run. Complete networks of machines are packaged up as data; we refer to them as virtual appliances. The publisher of an appliance controls the software installed on the appliance, from the operating system to the applications, and is responsible for keeping the appliance up to date. These appliances can be configured by users to fit their needs; the configuration is captured such that it can be reapplied automatically when the appliance's software is updated. We have developed a compute utility, called the Collective, which assigns virtual appliances to hardware dynamically and automatically. By keeping software up to date, our approach prevents security break-ins due to fixed vulnerabilities.

A web-based virtual lighting simulator  

SciTech Connect

This paper is about a web-based ''virtual lighting simulator,'' which is intended to allow architects and lighting designers to quickly assess the effect of key parameters on the daylighting and lighting performance in various space types. The virtual lighting simulator consists of a web-based interface that allows navigation through a large database of images and data, which were generated through parametric lighting simulations. At its current form, the virtual lighting simulator has two main modules, one for daylighting and one for electric lighting. The daylighting module includes images and data for a small office space, varying most key daylighting parameters, such as window size and orientation, glazing type, surface reflectance, sky conditions, time of the year, etc. The electric lighting module includes images and data for five space types (classroom, small office, large open office, warehouse and small retail), varying key lighting parameters, such as the electric lighting system, surface reflectance, dimming/switching, etc. The computed images include perspectives and plans and are displayed in various formats to support qualitative as well as quantitative assessment. The quantitative information is in the form of iso-contour lines superimposed on the images, as well as false color images and statistical information on work plane illuminance. The qualitative information includes images that are adjusted to account for the sensitivity and adaptation of the human eye. The paper also includes a section on the major technical issues and their resolution.

A COMPUTATIONAL WORKBENCH ENVIRONMENT FOR VIRTUAL POWER PLANT SIMULATION  

DOE Green Energy (OSTI)

In this report is described the work effort to develop and demonstrate a software framework to support advanced process simulations to evaluate the performance of advanced power systems. Integrated into the framework are a broad range of models, analysis tools, and visualization methods that can be used for the plant evaluation. The framework provides a tightly integrated problem-solving environment, with plug-and-play functionality, and includes a hierarchy of models, ranging from fast running process models to detailed reacting CFD models. The framework places no inherent limitations on the type of physics that can be modeled, numerical techniques, or programming languages used to implement the equipment models, or the type or amount of data that can be exchanged between models. Tools are provided to analyze simulation results at multiple levels of detail, ranging from simple tabular outputs to advanced solution visualization methods. All models and tools communicate in a seamless manner. The framework can be coupled to other software frameworks that provide different modeling capabilities. Three software frameworks were developed during the course of the project. The first framework focused on simulating the performance of the DOE Low Emissions Boiler System Proof of Concept facility, an advanced pulverized-coal combustion-based power plant. The second framework targeted simulating the performance of an Integrated coal Gasification Combined Cycle - Fuel Cell Turbine (IGCC-FCT) plant configuration. The coal gasifier models included both CFD and process models for the commercially dominant systems. Interfacing models to the framework was performed using VES-Open, and tests were performed to demonstrate interfacing CAPE-Open compliant models to the framework. The IGCC-FCT framework was subsequently extended to support Virtual Engineering concepts in which plant configurations can be constructed and interrogated in a three-dimensional, user-centered, interactive, immersive environment. The Virtual Engineering Framework (VEF), in effect a prototype framework, was developed through close collaboration with NETL supported research teams from Iowa State University Virtual Reality Applications Center (ISU-VRAC) and Carnegie Mellon University (CMU). The VEF is open source, compatible across systems ranging from inexpensive desktop PCs to large-scale, immersive facilities and provides support for heterogeneous distributed computing of plant simulations. The ability to compute plant economics through an interface that coupled the CMU IECM tool to the VEF was demonstrated, and the ability to couple the VEF to Aspen Plus, a commercial flowsheet modeling tool, was demonstrated. Models were interfaced to the framework using VES-Open. Tests were performed for interfacing CAPE-Open-compliant models to the framework. Where available, the developed models and plant simulations have been benchmarked against data from the open literature. The VEF has been installed at NETL. The VEF provides simulation capabilities not available in commercial simulation tools. It provides DOE engineers, scientists, and decision makers with a flexible and extensible simulation system that can be used to reduce the time, technical risk, and cost to develop the next generation of advanced, coal-fired power systems that will have low emissions and high efficiency. Furthermore, the VEF provides a common simulation system that NETL can use to help manage Advanced Power Systems Research projects, including both combustion- and gasification-based technologies.

The Universe Adventure - Expansion  

NLE Websites -- All DOE Office Websites (Extended Search)

Expansion: Chunk-by-Chunk Expansion: Chunk-by-Chunk A sample of the Universe. A very small portion of the Universe. In order to better understand the significance of expansion, let's look at a cubic sample of space. By considering a finite volume we can follow changes in the size of the Universe as we move forwards and backwards in time. Remember, only the size of the cube will change. The galaxies inside the cube stay the same size. This animation illustrates how our cubic piece of the Universe changes with time. If the Universe followed the simplest expansionary models, its size would increase linearly with time. The Universe would continue to expand at a constant rate forever. If you look at only a narrow time-slice of the Universe's history, it does, in fact, appear that this is how the Universe

Virtual environments for nuclear power plant design  

SciTech Connect

In the design and operation of nuclear power plants, the visualization process inherent in virtual environments (VE) allows for abstract design concepts to be made concrete and simulated without using a physical mock-up. This helps reduce the time and effort required to design and understand the system, thus providing the design team with a less complicated arrangement. Also, the outcome of human interactions with the components and system can be minimized through various testing of scenarios in real-time without the threat of injury to the user or damage to the equipment. If implemented, this will lead to a minimal total design and construction effort for nuclear power plants (NPP).

Beam discharge excited by distributed virtual cathode  

Science Conference Proceedings (OSTI)

A new type of beam discharge, i.e., beam discharge with a distributed virtual cathode (VC) is proposed and considered by numerical simulation. The discharge is established during counter motion of high-current electron beams in a gas-filled equipotential cavity and is characterized by a state of hot dense electron plasma of primary electrons. The discharge temporal dynamics is studied. It is shown that the VC lifetime depends linearly from this sum in a wide range of the sum of beam currents, from the boundary current of two-beam instability to the critical current of Pierce instability. Generation of nonlinear electrostatic structures shaped as phase bubbles in the discharge is detected, and their dynamics is studied. The parameters are determined, at which the multiple coexistence of phase bubbles and their coalescence during collisions is observed.

Unitary constraints on Deeply Virtual Compton Scattering  

SciTech Connect

At moderately low momentum transfer ($-t$ up to 1 GeV$^2$) the coupling to the vector meson production channels gives the dominant contribution to real Compton and deeply virtual Compton scattering (DVCS). Starting from a Regge Pole approach that successfully describes vector meson production, the singular part of the corresponding box diagrams (where the intermediate vector meson-baryon pair propagates on-shell) is evaluated without any further assumptions (unitarity). Such a treatment explains not only the unexpectedly large DVCS unpolarized cross section that has been recently measured at Jefferson Laboratory (JLab), but also all the beam spin and charge asymmetries that has been measured at JLab and Hermes, without explicit need of Generalized Parton Distributions (GPD). The issue of the relationship between the two approaches is addressed.

Virtual radiation fields -- A virtual environment tool for radiological analysis and simulation  

Science Conference Proceedings (OSTI)

A virtual reality system was developed for computational and graphical modeling and simulation of radiation environments. This system, called Virtual Radiation Fields (VRF), demonstrates the usefulness of radiological analysis in simulation-based design for predicting radiation doses for robotic equipment and personnel working in a radiation environment. The system was developed for use in determining the radiation doses for robotic equipment to be used in tank-waste retrieval operations at the Hanford National Laboratory. As a reference case, specific application is made to simulate cleanup operations for Hanford tank C-106. A three-dimensional model representation of the tank and its predicted radiation levels are presented and analyzed. Tank cleanup operations were simulated to understand how radiation levels change during the cleanup phase and to predict cumulative radiation doses to robotic equipment to aid in the development of maintenance and replacement schedules.

Data Protection and Rapid Recovery From Attack With A Virtual Private File Server and Virtual Machine Appliances  

E-Print Network (OSTI)

When a personal computer is attacked, both personal data like digital photos and system configuration information like installed programs can be lost. To protect personal data, we house it in a file server virtual machine running on the same physical host and export it to other virtual machines running on the same host. We implement this private file server virtual machine using a modified version of an NFS server installed in a virtual machine under various virtualization environments such as Xen and VMware. We also demonstrate that by placing the users applications in a virtual machine rather than directly on the base machine we can provide near instant recovery of system configuration information. We quantify the costs of this architecture by comparing benchmarks running directly on a base operating system and accessing data in a local filesystem to those running in a guest operating system and accessing data in an NFS partition mounted from a file server virtual machine. We find that for Xen the overhead of read intensive workloads is at most 5 % and for write intensive workloads the overhead is at most 24%. For system benchmarks that stress CPU and memory performance, we see no noticeable degradation.

University Prosperity Game. Final report  

Science Conference Proceedings (OSTI)

Prosperity Games are an outgrowth and adaptation of move/countermove and seminar War Games. Prosperity Games are simulations that explore complex issues in a variety of areas including economics, politics, sociology, environment, education and research. These issues can be examined from a variety of perspectives ranging from a global, macroeconomic and geopolitical viewpoint down to the details of customer/supplier/market interactions in specific industries. All Prosperity Games are unique in that both the game format and the player contributions vary from game to game. This report documents the University Prosperity Game conducted under the sponsorship of the Anderson Schools of Management at the University of New Mexico. This Prosperity Game was initially designed for the roadmap making effort of the National Electronics Manufacturing Initiative (NEMI) of the Electronics Subcommittee of the Civilian Industrial Technology Committee under the aegis of the National Science and Technology Council. The game was modified to support course material in MGT 508, Ethical, Political, and Social Environment of Business. Thirty-five students participated as role players. In this educational context the game`s main objectives were to: (1) introduce and teach global competitiveness and business cultures in an experiential classroom setting; (2) explore ethical, political, and social issues and address them in the context of global markets and competition; and (3) obtain non-government views regarding the technical and non-technical (i.e., policy) issues developed in the NEMI roadmap-making endeavor. The negotiations and agreements made during the game, along with the student journals detailing the players feelings and reactions to the gaming experience, provide valuable insight into the benefits of simulation as an advanced learning tool in higher education.

We describe the process used in combining an existing computer simulation with both Virtual Reality (VR) input and output devices, and conventional visualization tools, so as to make the simulation easier to use and the results easier to understand. VR input technology facilitates direct user manipulation of three dimensional simulation parameters. Commercially available visualization tools provide a flexible environment for representing abstract scientific data. VR output technology provides a more flexible and convincing way to view the visualization results than is afforded in contemporary visualization software. The desired goal of this process is a prototype system that minimizes man-machine interface barriers, as well as enhanced control over the simulation itself, so as to maximize the use of scientific judgement and intuition. In environmental remediation, the goal is to clean up contaminants either by removing them or rendering them non-toxic. A computer model simulates water or chemical flooding to mobilize and extract hydrocarbon contaminants from a volume of saturated soil/rock. Several wells are drilled in the vicinity of the contaminant, water and/or chemicals are injected into some of the wells, and fluid containing the mobilized hydrocarbons is pumped out of the remaining wells. The user is tasked with finding well locations and pumping rates that maximize recovery of the contaminants while minimizing drilling and pumping costs to clean up the site of interest.

Structured Query Language for Virtual Observatory  

E-Print Network (OSTI)

Currently two query languages are defined as standards for the Virtual Observatory (VO). Astronomical Data Query Language (ADQL) is used for catalog data query and Simple Image Access Protocol (SIAP) is for image data query. As a result, when we query each data service, we need to know in advance which language is supported and then construct a query language accordingly. The construct of SIAP is simple, but they have a limited capability. For example, there is no way to specify multiple regions in one query, and it is difficult to specify complex query conditions. In this paper, we propose a unified query language for any kind of astronomical database on the basis of SQL99. SQL is a query language optimized for a table data, so to apply the SQL to the image and spectrum data set, the data structure need to be mapped to a table like structure. We present specification of this query language and an example of the architecture for the database system.

Quantum mechanical Universal constructor  

E-Print Network (OSTI)

Arbitrary quantum states cannot be copied. In fact, to make a copy we must provide complete information about the system. However, can a quantum system self-replicate? This is not answered by the no-cloning theorem. In the classical context, Von Neumann showed that a `universal constructor' can exist which can self-replicate an arbitrary system, provided that it had access to instructions for making copy of the system. We question the existence of a universal constructor that may allow for the self-replication of an arbitrary quantum system. We prove that there is no deterministic universal quantum constructor which can operate with finite resources. Further, we delineate conditions under which such a universal constructor can be designed to operate dterministically and probabilistically.

Thermodynamics of Fractal Universe  

E-Print Network (OSTI)

We investigate the thermodynamical properties of the apparent horizon in a fractal universe. We find that one can always rewrite the Friedmann equation of the fractal universe in the form of the entropy balance relation $ \\delta Q=T_h d{S_h}$, where $ \\delta Q $ and $ T_{h} $ are the energy flux and Unruh temperature seen by an accelerated observer just inside the apparent horizon. We find that the entropy $S_h$ consists two terms, the first one which obeys the usual area law and the second part which is the entropy production term due to nonequilibrium thermodynamics of fractal universe. This shows that in a fractal universe, a treatment with nonequilibrium thermodynamics of spacetime may be needed. We also study the generalized second law of thermodynamics in the framework of fractal universe. When the temperature of the apparent horizon and the matter fields inside the horizon are equal, i.e. $T=T_h$, the generalized second law of thermodynamics can be fulfilled provided the deceleration and the equation of state parameters ranges either as $-1 \\leq q thermodynamics can be secured in a fractal universe by suitably choosing the fractal parameter $\\beta$.

Towards the Integration of APECS and VE-Suite for Virtual Power Plant Co-Simulation  

SciTech Connect

Process modeling and simulation tools are widely used for the design and operation of advanced power generation systems. These tools enable engineers to solve the critical process systems engineering problems that arise throughout the lifecycle of a power plant, such as designing a new process, troubleshooting a process unit or optimizing operations of the full process. To analyze the impact of complex thermal and fluid flow phenomena on overall power plant performance, the Department of Energys (DOE) National Energy Technology Laboratory (NETL) has developed the Advanced Process Engineering Co-Simulator (APECS). The APECS system is an integrated software suite that combines process simulation (e.g., Aspen Plus) and high-fidelity equipment simulations such as those based on computational fluid dynamics (CFD), together with advanced analysis capabilities including case studies, sensitivity analysis, stochastic simulation for risk/uncertainty analysis, and multi-objective optimization. In this paper we discuss the initial phases of the integration of the APECS system with the immersive and interactive virtual engineering software, VE-Suite, developed at Iowa State University and Ames Laboratory. VE-Suite uses the ActiveX (OLE Automation) controls in the Aspen Plus process simulator wrapped by the CASI library developed by Reaction Engineering International to run process/CFD co-simulations and query for results. This integration represents a necessary step in the development of virtual power plant co-simulations that will ultimately reduce the time, cost, and technical risk of developing advanced power generation systems.

Exploration of deeply virtual Compton scattering on the neutron in the Hall A of Jefferson Laboratory  

SciTech Connect

Generalized Parton Distributions (GPDs) are universal functions which provide a comprehensive description of hadron properties in terms of quarks and gluons. Deeply Virtual Compton Scattering (DVCS) is the simplest hard exclusive process involving GPDs. In particular, the DVCS on the neutron is mostly sensitive to E, the less constrained GPD, wich allows to access to the quark angular momentum. The first dedicated DVCS experiment on the neutron ran in the Hall A of Jefferson Lab in fall 2004. The high luminosity of the experiment and the resulting background rate recquired specific devices which are decribed in this document. The analysis methods and the experiment results, leading to preliminary constraints on the GPD E, are presented.

Universe Adventure Web Standards

Universe Universe Adventure Web Standards for the Smart Physics Student Author: Patrick Lii - plii@ugastro.berkeley.edu Date: August 3, 2007 ABSTRACT You may be wondering: why are the Universe Adventure web standards so impor- tant? And why do I have to read this stupid document about them? The old versions of our site were plagued with messy (and faulty) coding: the pages were littered with broken links, missing images, broken flash files, and all sorts of other problems which made the site highly inaccessible. When we tried to fix these errors, we found that the coding was so incredibly messy that a simple edit like changing some of the words in a paragraph or adding an image took hours rather than minutes. In fact, the coding was so horrific that we simply constructed an entirely new site rather than making the laborious attempt to fix the old one. In order to make sure that future students working

Energy management for hypervisor-based virtual machines  

E-Print Network (OSTI)

Current approaches to power management are based on operating systems with full knowledge of and full control over the underlying hardware; the distributed nature of multi-layered virtual machine environments renders such approaches insufficient. In this paper, we present a novel framework for energy management in modular, multi-layered operating system structures. The framework provides a unified model to partition and distribute energy, and mechanisms for energy-aware resource accounting and allocation. As a key property, the framework explicitly takes the recursive energy consumption into account, which is spent, e.g., in the virtualization layer or subsequent driver components. Our prototypical implementation targets hypervisor-based virtual machine systems and comprises two components: a host-level subsystem, which controls machine-wide energy constraints and enforces them among all guest OSes and service components, and, complementary, an energy-aware guest operating system, capable of fine-grained applicationspecific energy management. Guest level energy management thereby relies on effective virtualization of physical energy effects provided by the virtual machine monitor. Experiments with CPU and disk devices and an external data acquisition system demonstrate that our framework accurately controls and stipulates the power consumption of individual hardware devices, both for energy-aware and energyunaware guest operating systems. 1

EGR Distribution in Engine Cylinders Using Advanced Virtual Simulation  

DOE Green Energy (OSTI)

Exhaust Gas Recirculation (EGR) is a well-known technology for reduction of NOx in diesel engines. With the demand for extremely low engine out NOx emissions, it is important to have a consistently balanced EGR flow to individual engine cylinders. Otherwise, the variation in the cylinders' NOx contribution to the overall engine emissions will produce unacceptable variability. This presentation will demonstrate the effective use of advanced virtual simulation in the development of a balanced EGR distribution in engine cylinders. An initial design is analyzed reflecting the variance in the EGR distribution, quantitatively and visually. Iterative virtual lab tests result in an optimized system.

Expansion of the Universe Expansion of the Universe Redshift Expansion of Space Redshifts Light The expansion of space redshifts light. As space expands, light waves get stretched and their wavelengths shift. The more that light is stretched, the longer its wavelengths become, and the color of each wave shifts toward the red end of the light spectrum. We say that this light is redshifted. The Doppler Effect in action. A moving fire truck's siren changes pitch as it moves past you. This is known as the Doppler Effect. To get a better idea of how this actually works, we'll look at a common phenomenon: the Doppler Effect. Imagine you hear a fire truck coming right toward you.

Our View of the Universe Our View of the Universe All observations that have been made using the most powerful telescopes show that the universe looks the same in all directions. The average density of galaxies is the same throughout the universe and does not change with distance or direction. This is called the Cosmological Principle. Distribution of Galaxies On average and at large scales, the distribution of galaxies is the same throughout the universe. Since the expansion of space occurs evenly at every point in the universe, galaxies are separating from each other at about the same pace, giving the universe a nearly uniform density and structure. As a result, the universe appears smooth at large distance scales. In scientific terms, it is said to be homogeneous and isotropic.

Teaching and learning physics: A model for coordinating physics instruction, outreach, and research  

E-Print Network (OSTI)

This paper describes the development of a new university physics course designed to integrate physics, education, research, and community partnerships. The coordinated system of activities links the new course to local community efforts in pre-college education, university education, university outreach, and research on teaching and learning. As documented both by gains on conceptual surveys and by qualitative analyses of field-notes and audiotapes of class, the course facilitates student learning of physics, as well as student mastery of theories and practices of teaching and learning physics. Simultaneously, the course supports university efforts in community outreach and creates a rich environment for education research. The following narrative describes the motivation, structure, implementation, effectiveness, and potential for extending and sustaining this alternative model for university level science education.

Training managers: a case study of a French corporate university  

E-Print Network (OSTI)

This paper will analyze the learning design from the learning designers and trainers point of view. Focusing on the training system, we use a threefold model: ideational, functional and experienced dimensions of a training system. In the French public mail company, training for all managers is provided by a department of the Corporate University: the School of Managers. How has the project evolved since the original plan? If there are some gaps, how can we analyze the fact that, when it comes to innovation, "things never go exactly as planned"? Using interviews with designers and trainers involved in this project (N=7), we present the results of a discourse analysis performed with computer-assisted software. Answering the main goals of the research, the results will help us to better understand the prior ideas of the people in charge of the original system about (a) professionalization of managers, and (b) emotional and socioaffective dimensions of learning.
