Visual Data Analysis as an Integral Part of Environmental Management  

Science Conference Proceedings (OSTI)

The U.S. Department of Energy's (DOE) Office of Environmental Management (DOE/EM) currently supports an effort to understand and predict contaminant fate and transport in natural and engineered systems. Geologists, hydrologists, physicists and computer scientists are working together to create models of existing contaminated sites and to simulate their behavior. Simulation results are verified based on historical data and extrapolated into the future. Visualization is used for model setup verification, visual analysis of high-performance computing simulation results, and uncertainty quantification. This article describes the challenges and solutions for visual data analysis, which impacts the decision-making process for each of the contaminated sites. Lessons learned from these simulations will also have an impact on deciding on treatment measures for other, similarly contaminated areas, including those affected by more recent events, such as Chernobyl and Fukushima.

Visualizing Diurnal Population Change in Urban Areas for Emergency Management  

SciTech Connect

There is an increasing need for a quick, simple method to represent diurnal population change in metropolitan areas for effective emergency management and risk analysis. Many geographic studies rely on decennial U.S. Census data that assume that urban populations are static in space and time. This has obvious limitations in the context of dynamic geographic problems. The U.S. Department of Transportation publishes population data at the transportation analysis zone level in fifteen-minute increments. This level of spatial and temporal detail allows for improved dynamic population modeling. This article presents a methodology for visualizing and analyzing diurnal population change for metropolitan areas based on this readily available data. Areal interpolation within a geographic information system is used to create twenty-four (one per hour) population surfaces for the larger metropolitan area of Salt Lake County, Utah. The resulting surfaces represent diurnal population change for an average workday and are easily combined to produce an animation that illustrates population dynamics throughout the day. A case study of using the method to visualize population distributions in an emergency management context is provided using two scenarios: a chemical release and a dirty bomb in Salt Lake County. This methodology can be used to address a wide variety of problems in emergency management.

The Role of Visualization Systems in Managing the Energy of Production Systems  

E-Print Network (OSTI)

The convergence of sustainability pressures, rising energy prices, and insatiable demand all will have a profound impact on our relationship with energy and its effect on the macro economy. There's no shortage of industrial users eager to turn crisis into future profits by taking the steps to gain control over energy costs and consumption. All this promise has led to the expansion of the presence of energy visualization products, or energy management dashboards, which all claim to offer unique features and attributes that enable the superior management of energy resources. Many of these systems are designed to optimize the energy of building systems and utilities: HVAC, water distribution, pneumatics, boilers, etc. In a typical industrial process facility, however, these systems account for only 16 percent of the energy demand. This paper highlights the potential of energy optimization of production systems, and defines five proven techniques, called process demand functions, that can be leveraged to mitigate process energy. For each process demand function, the role of the visualization system will be highlighted

Phase contrast imaging of cochlear soft tissue.  

SciTech Connect

A noninvasive technique to image soft tissue could expedite diagnosis and disease management in the auditory system. We propose inline phase contrast imaging with hard X-rays as a novel method that overcomes the limitations of conventional absorption radiography for imaging soft tissue. In this study, phase contrast imaging of mouse cochleae was performed at the Argonne National Laboratory Advanced Photon Source. The phase contrast tomographic reconstructions show soft tissue structures of the cochlea, including the inner pillar cells, the inner spiral sulcus, the tectorial membrane, the basilar membrane, and the Reissner's membrane. The results suggest that phase contrast X-ray imaging and tomographic techniques hold promise to noninvasively image cochlear structures at an unprecedented cellular level.

Management  

E-Print Network (OSTI)

Research has indicated that, depending upon driver and passenger characteristics, passengers can have either a positive or negative influence upon driver behaviour. In conclusion to a recent study investigating the roles that passengers can play to influence, positively and negatively, driver behaviour, Regan and Mitsopoulos (2001) recommended, among other things, that the principles of Crew Resource Management (CRM) training may increase passengers ability to positively influence driver behaviour and also drivers ability to accept constructive feedback. The present study investigated the potential application of CRM training within young driver training in the Australian Capital Territory (ACT). This involved a literature review, an analysis of the differences between the driving and aviation domains, an analysis of the team-based activities and the knowledge, skills and attitudes required during driving to perform those activities, consultation with CRM experts from the aviation and medicine domains and the conduct of six focus groups involving young learner drivers, provisional licence drivers and course teachers. The findings indicate that CRM training as part of young driver training in the ACT is a viable concept to pursue. The application of CRM training within young driver training has potential to significantly enhance the positive and reduce the negative effects of passengers on young driver behaviour, and thus the safety of young drivers and passengers alike. The outcomes of this study formed the basis for a set of recommendations for the development of a young driver CRM training program in the ACT.

High Quality Image of Biomedical Object by X-ray Refraction Based Contrast Computed Tomography  

SciTech Connect

Recently we have developed a new Computed Tomography (CT) algorithm for refraction contrast that uses the optics of diffraction-enhanced imaging. We applied this new method to visualize soft tissue which is not visualized by the current absorption based contrast. The meaning of the contrast that appears in refraction-contrast X-ray CT images must be clarified from a biologic or anatomic point of view. It has been reported that the contrast is made with the specific gravity map with a range of approximately 10 {mu}arc sec. However, the relationship between the contrast and biologic or anatomic findings has not been investigated, to our knowledge. We compared refraction-contrast X-ray CT images with microscopic X-ray images, and we evaluated refractive indexes of pathologic lesions on phase-contrast X-ray CT images. We focused our attenuation of breast cancer and lung cancer as samples. X-ray refraction based Computed Tomography was appeared to be a pathological ability to depict the boundary between cancer nest and normal tissue, and inner structure of the disease.

Designing Effective Algorithm Visualizations  

E-Print Network (OSTI)

Advances in computing technology and the aordability of software and high-performance graphics hardware enabled rapid growth of visual tools. Today, not only very expensive workstations, but also low-cost PCs are capable of running computationally demanding visualization systems. Algorithm visualizations or the graphic depiction of algorithms in execution have been used in explaining, designing and analyzing algorithms since the early 1980s. Although many tools have been developed over the past twenty years, not enough attention has been paid to the analysis of users, their needs, tasks, and goals. This paper provides an overview of algorithm visualization techniques, based on the premise that a rethinking of algorithm animation design is required in order to harness its power for enhancing learning. More information about the topic can be found on the author's web page. 1

An Assessment of Visual Testing  

SciTech Connect

In response to increasing interest from nuclear utilities in replacing some volumetric examinations of nuclear reactor components with remote visual testing, the Pacific Northwest National Laboratory has examined the capabilities of remote visual testing for the Nuclear Regulatory Commission. This report describes visual testing and explores the visual acuities of the camera systems used to examine nuclear reactor components. The types and sizes of cracks typically found in nuclear reactor components are reviewed. The current standards in visual testing are examined critically, and several suggestions for improving these standards are proposed. Also proposed for future work is a round robin test to determine the effectiveness of visual tests and experimental studies to determine the values for magnification and resolution needed to reliably image very tight cracks.

3D Visualization of Water Transport in Ferns  

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

3D Visualization of Water Transport 3D Visualization of Water Transport in Ferns 3D Visualization of Water Transport in Ferns Print Monday, 08 April 2013 00:00 Plants transport water through elongated cells called xylem. However, in trees such as eucalyptus or redwood, the xylem tissue-better known as wood-bears the weight of the branches and leaves, giving rise to the often massive canopies characteristic of these species. We know much about water transport in woody plants, but considerably less about primitive plants such as ferns. Not only have ferns played an important role in the evolution of trees and shrubs but collectively, these plant forms are a fascinating study in contrasts because ferns use xylem strictly for water transport, leaving structural support to other tissues. Given the global distribution and impressive diversity of ferns, how has their xylem evolved to deal with variable habitat water availability?

This patent relates to a device for developing a phase contrast signal for a scanning transmission electron microscope. The lens system of the microscope is operated in a condition of defocus so that predictable alternate concentric regions of high and low electron density exist in the cone of illumination. Two phase detectors are placed beneath the object inside the cone of illumination, with the first detector having the form of a zone plate, each of its rings covering alternate regions of either higher or lower electron density. The second detector is so configured that it covers the regions of electron density not covered by the first detector. Each detector measures the number of electrons incident thereon and the signal developed by the first detector is subtracted from the signal developed by the record detector to provide a phase contrast signal.

High Performance Multivariate Visual Data Exploration for Extremely Large Data  

SciTech Connect

One of the central challenges in modern science is the need to quickly derive knowledge and understanding from large, complex collections of data. We present a new approach that deals with this challenge by combining and extending techniques from high performance visual data analysis and scientific data management. This approach is demonstrated within the context of gaining insight from complex, time-varying datasets produced by a laser wakefield accelerator simulation. Our approach leverages histogram-based parallel coordinates for both visual information display as well as a vehicle for guiding a data mining operation. Data extraction and subsetting are implemented with state-of-the-art index/query technology. This approach, while applied here to accelerator science, is generally applicable to a broad set of science applications, and is implemented in a production-quality visual data analysis infrastructure. We conduct a detailed performance analysis and demonstrate good scalability on a distributed memory Cray XT4 system.

Advances in reactor physics education: Visualization of reactor parameters  

Science Conference Proceedings (OSTI)

Modern computer codes allow detailed neutron transport calculations. In combination with advanced 3D visualization software capable of treating large amounts of data in real time they form a powerful tool that can be used as a convenient modern educational tool for reactor operators, nuclear engineers, students and specialists involved in reactor operation and design. Visualization is applicable not only in education and training, but also as a tool for fuel management, core analysis and irradiation planning. The paper treats the visualization of neutron transport in different moderators, neutron flux and power distributions in two nuclear reactors (TRIGA type research reactor and a typical PWR). The distributions are calculated with MCNP and CORD-2 computer codes and presented using Amira software. (authors)

Static contrast enhancement layer for photolithographic processes  

DOE Patents (OSTI)

In the ever expanding microelectronic industry, there is a constant demand for improved photolithographic techniques useful in the manufacture of integrated circuits and the like. Over the years, however, the linewidths of structures patterned for microelectronic fabrication have continued to decrease. At present, 0.8 {mu}m lines and spaces are now imaged in commercial production and much smaller features are predicted for the near future. These feature sizes represent a significant drop below the previously predicted limit of optical lithography, originally thought to be around 1.25 {mu}m. These advances have been due in large part to the extensive worldwide research effort in improved optical patterning techniques. One of the more significant developments in optical patterning has been the advent of contrast enhancement layer lithography. A static stable contrast enhancement layer is provided for improving the resolution possible in photolithographic processes which comprises a photoacid generator such as an onium salt and acid-base indicator dye such as methyl yellow incorporated into a polymeric binder. The contrast enhancement layer is coated onto a conventional photoresist, and upon exposure to light in the appropriate absorption range, the salt undergoes a transformation to a strong Bronsted acid which will then bleach the indicator dye. The system is particularly designed so that an in situ contact mask is formed in a first deep UV exposure which is used to mask light projected upon the photoresist at a second wavelength.

Accelerating Network Traffic Analytics Using Query-DrivenVisualization  

SciTech Connect

Realizing operational analytics solutions where large and complex data must be analyzed in a time-critical fashion entails integrating many different types of technology. This paper focuses on an interdisciplinary combination of scientific data management and visualization/analysis technologies targeted at reducing the time required for data filtering, querying, hypothesis testing and knowledge discovery in the domain of network connection data analysis. We show that use of compressed bitmap indexing can quickly answer queries in an interactive visual data analysis application, and compare its performance with two alternatives for serial and parallel filtering/querying on 2.5 billion records worth of network connection data collected over a period of 42 weeks. Our approach to visual network connection data exploration centers on two primary factors: interactive ad-hoc and multiresolution query formulation and execution over n dimensions and visual display of then-dimensional histogram results. This combination is applied in a case study to detect a distributed network scan and to then identify the set of remote hosts participating in the attack. Our approach is sufficiently general to be applied to a diverse set of data understanding problems as well as used in conjunction with a diverse set of analysis and visualization tools.

A method for developing visually intelligent construction scheduling data  

E-Print Network (OSTI)

The integration of methods, materials, and manpower is the basis for planning the activities of a construction project. The scheduling of these resources used during the construction of buildings is a critical factor that can dramatically affect a project's budget, timeline, and overall success. Consequently, much effort should be placed on the schedule's development to define an accurate timeline of predicted construction activities. To aid this effort, tools such as activity-based simulation models and three-dimensional visualization techniques have been utilized to improve the accuracy of scheduling. While simulation models use general programming language to create numeric models of processes in areas of management and manufacturing, construction visualization allows still and animated visual analyses of three-dimensional virtual worlds. Thus, this research integrates numerical activity-based simulation with visual animation to create optimized and intelligent construction scheduling data. This integration improves the accuracy, prediction, and comprehensive capability of construction schedules. The results show that efficiently scheduled construction processes can be created to reduce time and costs and provide visual training data for the owners, contractors, and workers.

A Flexible Approach for the Statistical Visualization of Ensemble Data  

SciTech Connect

Scientists are increasingly moving towards ensemble data sets to explore relationships present in dynamic systems. Ensemble data sets combine spatio-temporal simulation results generated using multiple numerical models, sampled input conditions and perturbed parameters. While ensemble data sets are a powerful tool for mitigating uncertainty, they pose significant visualization and analysis challenges due to their complexity. We present a collection of overview and statistical displays linked through a high level of interactivity to provide a framework for gaining key scientific insight into the distribution of the simulation results as well as the uncertainty associated with the data. In contrast to methods that present large amounts of diverse information in a single display, we argue that combining multiple linked statistical displays yields a clearer presentation of the data and facilitates a greater level of visual data analysis. We demonstrate this approach using driving problems from climate modeling and meteorology and discuss generalizations to other fields.

Subterranean formation permeability contrast correction methods  

SciTech Connect

This patent describes a method of correcting the permeability contrast in a subterranean formation penetrated by a well bore to improve the sweep efficiency of waterflooding operations carried out therein, the formation containing at least one high permeability zone lying adjacent to at least one low permeability zone, which zones are in fluid communication with one another at the boundary therebetween. It comprises isolating the high permeability zone from the low permeability zone; injecting a crosslinkable aqueous polymer solution into the high permeability zone in an amount sufficient to substantially fill some the zone therewith, the crosslinkable aqueous polymer solution being capable of plugging the high permeability zone when crosslinked; isolating the low permeability zone from the high permeability zone; injecting into the low permeability zone an aqueous liquid containing a crosslinking agent which upon contact with the aqueous polymer solution causes the solution to form a crosslinked gel; and displacing the aqueous liquid containing the crosslinking agent through the low permeability zone so that the crosslinking agent contact the aqueous polymer solution and forms a crosslinked gel at least at the boundary between the zones whereby fluid communication between the zones is reduced and subsequently injected flood water is substantially confined to the low permeability zone.

Visual Outcome in Meningiomas Around Anterior Visual Pathways Treated With Linear Accelerator Fractionated Stereotactic Radiotherapy  

SciTech Connect

Purpose: Meningiomas threatening the anterior visual pathways (AVPs) and not amenable for surgery are currently treated with multisession stereotactic radiotherapy. Stereotactic radiotherapy is available with a number of devices. The most ubiquitous include the gamma knife, CyberKnife, tomotherapy, and isocentric linear accelerator systems. The purpose of our study was to describe a case series of AVP meningiomas treated with linear accelerator fractionated stereotactic radiotherapy (FSRT) using the multiple, noncoplanar, dynamic conformal rotation paradigm and to compare the success and complication rates with those reported for other techniques. Patients and Methods: We included all patients with AVP meningiomas followed up at our neuro-ophthalmology unit for a minimum of 12 months after FSRT. We compared the details of the neuro-ophthalmologic examinations and tumor size before and after FSRT and at the end of follow-up. Results: Of 87 patients with AVP meningiomas, 17 had been referred for FSRT. Of the 17 patients, 16 completed >12 months of follow-up (mean 39). Of the 16 patients, 11 had undergone surgery before FSRT and 5 had undergone FSRT as first-line management. Tumor control was achieved in 14 of the 16 patients, with three meningiomas shrinking in size after RT. Two meningiomas progressed, one in an area that was outside the radiation field. The visual function had improved in 6 or stabilized in 8 of the 16 patients (88%) and worsened in 2 (12%). Conclusions: Linear accelerator fractionated RT using the multiple noncoplanar dynamic rotation conformal paradigm can be offered to patients with meningiomas that threaten the anterior visual pathways as an adjunct to surgery or as first-line treatment, with results comparable to those reported for other stereotactic RT techniques.

Visualizing Gene Expression In Situ  

Science Conference Proceedings (OSTI)

Visualizing bacterial cells and describing their responses to the environment are difficult tasks. Their small size is the chief reason for the difficulty, which means that we must often use many millions of cells in a sample in order to determine what the average response of the bacteria is. However, an average response can sometimes mask important events in bacterial physiology, which means that our understanding of these organisms will suffer. We have used a variety of instruments to visualize bacterial cells, all of which tell us something different about the sample. We use a fluorescence activated cell sorter to sort cells based on the fluorescence provided by bioreporter genes, and these can be used to select for particular genetic mutations. Cells can be visualized by epifluorescent microscopy, and sensitive photodetectors can be added that allow us to find a single bacterial cell that is fluorescent or bioluminescent. We have also used standard photomultipliers to examine cell aggregates as field bioreporter microorganisms. Examples of each of these instruments show how our understanding of bacterial physiology has changed with the technology.

They recommend the installation of a visual alarm system to supplement the page/party phone system The purpose of this analysis is to identify data communication highway design approaches, and provide justification for the selected or recommended alternatives for the data communication of the subsurface visual alarm system. This analysis is being prepared to document a basis for the design selection of the data communication method. This analysis will briefly describe existing data or voice communication or monitoring systems within the ESF, and look at how these may be revised or adapted to support the needed data highway of the subsurface visual alarm. system. The existing PLC communication system installed in subsurface is providing data communication for alcove No.5 ventilation fans, south portal ventilation fans, bulkhead doors and generator monitoring system. It is given that the data communication of the subsurface visual alarm system will be a digital based system. It is also given that it is most feasible to take advantage of existing systems and equipment and not consider an entirely new data communication system design and installation. The scope and primary objectives of this analysis are to: (1) Briefly review and describe existing available data communication highways or systems within the ESF. (2) Examine technical characteristics of an existing system to disqualify a design alternative is paramount in minimizing the number of and depth of a system review. (3) Apply general engineering design practices or criteria such as relative cost, and degree of difficulty and complexity in determining requirements in adapting existing data communication highways to support the subsurface visual alarm system. These requirements would include such things as added or new communication cables, added Programmable Logic Controller (PLC), Inputs and Outputs (I/O), and communication hardware components, and human machine interfaces and their software operating system. (4) Select the best data communication highway system based on this review of adapting or integrating with existing data communication systems.

Visualizing large data sets in the earth sciences  

SciTech Connect

With single data sets containing billions of points, meteorologists and other earth scientists face an avalanche of data received from their remote-sensing instruments and numerical simulation models. The Space Science and Engineering Center (SSEC) at the University of Wisconsin-Madison led the evolution of weather visualization systems from paper to electronic displays with their Mancomputer Interactive Data Access System (MCIDAS). They have continued this evolution into animated three-dimensional images and recently into highly interactive displays. Their software can manage, analyze, and visualize large data sets that span many physical variables (such as temperature, pressure, humidity, and wind speed), as well as time and three spatial dimensions. McIDAS has produced three-dimensional animations of data sets from many diverse sources on videotape and on a special binocular stereo workstation. Its applications are discussed in this paper.

Visualization of Scalar Adaptive Mesh Refinement Data  

SciTech Connect

Adaptive Mesh Refinement (AMR) is a highly effective computation method for simulations that span a large range of spatiotemporal scales, such as astrophysical simulations, which must accommodate ranges from interstellar to sub-planetary. Most mainstream visualization tools still lack support for AMR grids as a first class data type and AMR code teams use custom built applications for AMR visualization. The Department of Energy's (DOE's) Science Discovery through Advanced Computing (SciDAC) Visualization and Analytics Center for Enabling Technologies (VACET) is currently working on extending VisIt, which is an open source visualization tool that accommodates AMR as a first-class data type. These efforts will bridge the gap between general-purpose visualization applications and highly specialized AMR visual analysis applications. Here, we give an overview of the state of the art in AMR scalar data visualization research.

Visualization on supercomputing platform level II ASC milestone (3537-1B) results from Sandia.  

SciTech Connect

This report provides documentation for the completion of the Sandia portion of the ASC Level II Visualization on the platform milestone. This ASC Level II milestone is a joint milestone between Sandia National Laboratories and Los Alamos National Laboratories. This milestone contains functionality required for performing visualization directly on a supercomputing platform, which is necessary for peta-scale visualization. Sandia's contribution concerns in-situ visualization, running a visualization in tandem with a solver. Visualization and analysis of petascale data is limited by several factors which must be addressed as ACES delivers the Cielo platform. Two primary difficulties are: (1) Performance of interactive rendering, which is most computationally intensive portion of the visualization process. For terascale platforms, commodity clusters with graphics processors(GPUs) have been used for interactive rendering. For petascale platforms, visualization and rendering may be able to run efficiently on the supercomputer platform itself. (2) I/O bandwidth, which limits how much information can be written to disk. If we simply analyze the sparse information that is saved to disk we miss the opportunity to analyze the rich information produced every timestep by the simulation. For the first issue, we are pursuing in-situ analysis, in which simulations are coupled directly with analysis libraries at runtime. This milestone will evaluate the visualization and rendering performance of current and next generation supercomputers in contrast to GPU-based visualization clusters, and evaluate the performance of common analysis libraries coupled with the simulation that analyze and write data to disk during a running simulation. This milestone will explore, evaluate and advance the maturity level of these technologies and their applicability to problems of interest to the ASC program. Scientific simulation on parallel supercomputers is traditionally performed in four sequential steps: meshing, partitioning, solver, and visualization. Not all of these components are necessarily run on the supercomputer. In particular, the meshing and visualization typically happen on smaller but more interactive computing resources. However, the previous decade has seen a growth in both the need and ability to perform scalable parallel analysis, and this gives motivation for coupling the solver and visualization.

Optimal Seabed Habitat Mapping Using Multibeam Acoustics with Associated Physical and Visual Sampling Devices - At Sea Trials  

E-Print Network (OSTI)

Australia is custodian to a large marine jurisdiction with associated seabed habitats that need to be managed for multiple use purposes. Mapping seabed habitats or their surrogates is a fundamental first step in this process, with methods that can map large areas of seabed such as multibeam swath mapping sonars representing attractive tools. A methodology of optimally mapping the seabed is presented using a swath mapper in conjunction with biophysical, geophysical and video/photographic devices. A Simrad EM1002 swath mapper was used in April 2000 to map selected sites on the shelf and upper slope. The swath mapper produced three data products (being, bathymetry, backscatter and sun illuminated bathymetry imagery) that were visually inspected to target the variety of substrate types. Limitations in the imagery were observed due to instrument frequency, beamwidth, pulse length, depth and across track resolution as well as changing oceanographic and weather conditions. The biophysical, geophysical and video/photographic sampling was targeted on the contrasting features in the imagery. The video/photographic sampling proved the best tool for understanding the backscatter images and their relation to geological and biological attributes. The swath mapper proved (not surprisingly) to be an invaluable tool for undertaking investigations of the seabed, providing higher resolution bathymetry and backscatter than our existing single beam devices. A significant advantage for habitat mapping was the reduction in time consuming direct and visual sampling by mapping out seabed regions of like character. The ability of the swath mapped bathymetry and backscatter to provide a surrogate for specific geological and biological attributes that are independent of instrument paramet...

Collaborative Visualization for Large-Scale Accelerator Electromagnetic Modeling  

SciTech Connect

In the Phase I SBIR we proposed a ParaView-based solution to provide an environment for individuals to actively collaborate in the visualization process. The technical objectives of Phase I were: (1) to determine the set of features required for an effect collaborative system; (2) to implement a two-person collaborative prototype; and (3) to implement key collaborative features such as control locking and annotation. Accordingly, we implemented a ParaView-based collaboration prototype with support for collaborating with up to four simultaneous clients. We also implemented collaborative features such as control locking, chatting, annotation etc. Due to in part of the flexibility provided by the ParaView framework and the design features implemented in the prototype, we were able to support collaboration with multiple views, instead of a simple give as initially proposed in Phase I. In this section we will summarize the results we obtained during the Phase I project. ParaView is complex, scalable, client-server application framework built on top of the VTK visualization engine. During the implementation of the Phase I prototype, we realized that the ParaView framework naturally supports collaboration technology; hence we were able to go beyond the proposed Phase I prototype in several ways. For example, we were able to support for multiple views, enable server-as well as client-side rendering, and manage up to four heterogeneous clients. The success we achieved with Phase I clearly demonstrated the technical feasibility of the ParaView based collaborative framework we are proposing in the Phase II effort. We also investigated using the web browser as one of the means of participating in a collaborative session. This would enable non-visualization experts to participate in the collaboration process without being intimidated by a complex application such as ParaView. Hence we also developed a prototype web visualization applet that makes it possible for interactive visualization over the web.

Visualization at Supercomputing Centers: The Tale of Little Big Iron and the Three Skinny Guys  

SciTech Connect

Supercomputing Centers (SC's) are unique resources that aim to enable scientific knowledge discovery through the use of large computational resources, the Big Iron. Design, acquisition, installation, and management of the Big Iron are activities that are carefully planned and monitored. Since these Big Iron systems produce a tsunami of data, it is natural to co-locate visualization and analysis infrastructure as part of the same facility. This infrastructure consists of hardware (Little Iron) and staff (Skinny Guys). Our collective experience suggests that design, acquisition, installation, and management of the Little Iron and Skinny Guys does not receive the same level of treatment as that of the Big Iron. The main focus of this article is to explore different aspects of planning, designing, fielding, and maintaining the visualization and analysis infrastructure at supercomputing centers. Some of the questions we explore in this article include:"How should the Little Iron be sized to adequately support visualization and analysis of data coming off the Big Iron?" What sort of capabilities does it need to have?" Related questions concern the size of visualization support staff:"How big should a visualization program be (number of persons) and what should the staff do?" and"How much of the visualization should be provided as a support service, and how much should applications scientists be expected to do on their own?"

Indirect MR lymphangiography of the head and neck using conventional gadolinium contrast: A pilot study in humans  

SciTech Connect

Purpose: To evaluate indirect magnetic resonance lymphangiography (MR-LAG) using interstitial injection of conventional gadolinium contrast (gadoteridol and gadopentetate dimeglumine) for delineating the primary lymphatic drainage of head-and-neck sites. Methods and Materials: We performed head-and-neck MR-LAG in 5 healthy volunteers, with injection of dermal and mucosal sites. We evaluated the safety of the procedure, the patterns of enhancement categorized by injection site and nodal level, the time course of enhancement, the optimal concentration and volume of contrast, and the optimal imaging sequence. Results: The worst side effects of interstitial contrast injection were brief, mild pain and swelling at the injected sites that were self-limited. MR-LAG resulted in consistent visualization of the primary lymphatic drainage pattern specific to each injected site, which was reproducible on repeated examinations. The best enhancement was obtained with injection of small volumes (0.3-0.5 mL) of either agent diluted, imaging within 5-15 min of injection, and a three-dimensional fast spoiled gradient echo sequence with magnetization transfer. Conclusions: We found head-and-neck MR-LAG to be a safe, convenient imaging method that provides functional information about the lymphatic drainage of injected sites. Applied to head-and-neck cancer, it has the potential to identify sites at highest risk of occult metastatic spread for radiotherapy or surgical planning, and possibly to visualize micrometastases.

Designing Educationally Effective Algorithm Visualizations  

E-Print Network (OSTI)

Despite the intuitively compelling adage "a picture is worth a thousand words," attempts over the past decade to use animations to explain algorithms to students have produced disappointing results. In most cases interesting algorithm animations were designed, but no formal, systematic evaluations were conducted. When such evaluations were performed the results were mixed, with compelling evidence for the instructional superiority of algorithm animations failing to emerge. It is in this context that we embarked on a research program to develop educationally effective algorithm visualizations. This program was based on the premise that animations needed to be embedded in a knowledge and context providing hypermedia environment in order to effectively harness their power to enhance learning. This paper describes the architecture of the resulting Hypermedia Algorithm Visualization system HalVis. Four empirical studies with HalVis are described, which demonstrated that the extent of learning exhibited by students who used HalVis was significantly greater than that of students who used means of traditional instruction or a typical algorithm animation.

Time course of information processing in visual and haptic object classification  

E-Print Network (OSTI)

Vision identifies objects rapidly and efficiently. In contrast, object recognition by touch is much slower. Furthermore, haptics usually serially accumulates information from different parts of objects, whereas vision typically processes object information in parallel. Is hap- tic object identification slower simply due to sequential information acquisition and the resulting memory load or due to more fundamental processing differences between the senses? To compare the time course of visual and haptic object recognition, we slowed visual processing using a novel, restricted viewing technique. In an electroencephalo- graphic (EEG) experiment, participants discriminated familiar, nameable from unfamiliar, unnamable objects both visually and haptically. Analyses focused on the evoked and total fronto-central theta-band (57 Hz; a marker of working memory) and the occipital upper alpha-band (1012 Hz; a marker of perceptual processing) locked to the onset of classi- fication. Decreases in total upper alpha-band activity for haptic identification of objects indicate a likely processing role of multisensory extrastriate areas. Long-latency modula- tions of alpha-band activity differentiated between familiar and unfamiliar objects in haptics but not in vision. In contrast, theta-band activity showed a general increase over time for the slowed-down visual recognition task only. We conclude that haptic object recognition relies on common representations with vision but also that there are fundamental differ- ences between the senses that do not merely arise from differences in their speed of processing.

Visually simulating realistic fluid motion  

E-Print Network (OSTI)

In this thesis we investigate various methods for visually simulating fluid flow. The focus is on implementing effective fluid simulation within an interactive animation system. Two implementations have been developed based on derivations and simplifications of the Navier-Stokes' equations. The first implementation is the most accurate and follows the physics of fluid dynamics more closely. However, the high computation times incurred by this implementation make it inappropriate as an interactive method. The second approach is not as accurate as the first one, however it incurs lower computation times. This second method is only able to model a subset of the total fluid behavior. The second method has been integrated into an interactive modeling and animation environment. Several examples are included.

First Generation ASCI Production Visualization Environments  

SciTech Connect

The delivery of the first one tera-operations/sec computer has significantly impacted production data visualization, affecting data transfer, post processing, and rendering. Terascale computing has motivated a need to consider the entire data visualization system; improving a single algorithm is not sufficient. This paper presents a systems approach to decrease by a factor of four the time required to prepare large data sets for visualization.For daily production use, all stages in the processing pipeline from physics simulation code to pixels on a screen, must be balanced to yield good overall performance. Also, to complete the data path from screen to the analyst's eye, user display systems for individuals and teams are examined. Performance of the initial visualization system is compared with recent improvements. Lessons learned from the coordinated deployment of improved algorithms are also discussed, including the need for 64 bit addressing and a fully parallel data visualization pipeline.

Visualization at Supercomputing Centers: The Tale of Little Big Iron and the Three Skinny Guys  

SciTech Connect

Supercomputing centers are unique resources that aim to enable scientific knowledge discovery by employing large computational resources - the 'Big Iron.' Design, acquisition, installation, and management of the Big Iron are carefully planned and monitored. Because these Big Iron systems produce a tsunami of data, it's natural to colocate the visualization and analysis infrastructure. This infrastructure consists of hardware (Little Iron) and staff (Skinny Guys). Our collective experience suggests that design, acquisition, installation, and management of the Little Iron and Skinny Guys doesn't receive the same level of treatment as that of the Big Iron. This article explores the following questions about the Little Iron: How should we size the Little Iron to adequately support visualization and analysis of data coming off the Big Iron? What sort of capabilities must it have? Related questions concern the size of visualization support staff: How big should a visualization program be - that is, how many Skinny Guys should it have? What should the staff do? How much of the visualization should be provided as a support service, and how much should applications scientists be expected to do on their own?

In-vivo imaging of the photoreceptor mosaic in retinal dystrophies and correlations with visual function  

SciTech Connect

To relate in-vivo microscopic retinal changes to visual function assessed with clinical tests in patients with various forms of retinal dystrophies. The UC Davis Adaptive Optics (AO) Fundus Camera was used to acquire in-vivo retinal images at the cellular level. Visual function tests, consisting of visual field analysis, multifocal electroretinography (mfERG), contrast sensitivity and color vision measures, were performed on all subjects. Five patients with different forms of retinal dystrophies and three control subjects were recruited. Cone densities were quantified for all retinal images. In all images of diseased retinas, there were extensive areas of dark space between groups of photoreceptors, where no cone photoreceptors were evident. These irregular features were not seen in healthy retinas, but were characteristic features in fundi with retinal dystrophies. There was a correlation between functional vision loss and the extent to which the irregularities occurred in retinal images. Cone densities were found to decrease with an associated decrease in retinal function. AO fundus photography is a reliable technique for assessing and quantifying the changes in the photoreceptor layer as disease progresses. Furthermore, this technique can be useful in cases where visual function tests give borderline or ambiguous results, as it allows visualization of individual photoreceptors.

Contrast analysis and stability on the ExAO testbed  

SciTech Connect

High-contrast adaptive optics systems, such as those needed to image extrasolar planets, are known to require excellent wavefront control and diffraction suppression. The Laboratory for Adaptive Optics at UC Santa Cruz is investigating limits to high-contrast imaging in support of the Gemini Planet Imager. Previous contrast measurements were made with a simple single-opening prolate spheroid shaped pupil that produced a limited region of high-contrast, particularly when wavefront errors were corrected with the 1024-actuator Boston Micromachines MEMS deformable mirror currently in use on the testbed. A more sophisticated shaped pupil is now being used that has a much larger region of interest facilitating a better understanding of high-contrast measurements. In particular we examine the effect of heat sources in the testbed on PSF stability. We find that rms image motion scales as 0.02 {lambda}/D per watt when the heat source is near the pupil plane. As a result heat sources of greater than 5 watts should be avoided near pupil planes for GPI. The safest place to introduce heat is near a focal plane. Heat also can effect the standard deviation of the high-contrast region but in the final instrument other sources of error should be more significant.

3D visualization of port simulation.  

SciTech Connect

Affordable and realistic three dimensional visualization technology can be applied to large scale constructive simulations such as the port simulation model, PORTSIM. These visualization tools enhance the experienced planner's ability to form mental models of how seaport operations will unfold when the simulation model is implemented and executed. They also offer unique opportunities to train new planners not only in the use of the simulation model but on the layout and design of seaports. Simulation visualization capabilities are enhanced by borrowing from work on interface design, camera control, and data presentation. Using selective fidelity, the designers of these visualization systems can reduce their time and efforts by concentrating on those features which yield the most value for their simulation. Offering the user various observational tools allows the freedom to simply watch or engage in the simulation without getting lost. Identifying the underlying infrastructure or cargo items with labels can provide useful information at the risk of some visual clutter. The PortVis visualization expands the PORTSIM user base which can benefit from the results provided by this capability, especially in strategic planning, mission rehearsal, and training. Strategic planners will immediately reap the benefits of seeing the impact of increased throughput visually without keeping track of statistical data. Mission rehearsal and training users will have an effective training tool to supplement their operational training exercises which are limited in number because of their high costs. Having another effective training modality in this visualization system allows more training to take place and more personnel to gain an understanding of seaport operations. This simulation and visualization training can be accomplished at lower cost than would be possible for the operational training exercises alone. The application of PORTSIM and PortVis will lead to more efficient planning overall and ultimately increase port utilization and throughput, decreasing the amount of time required to transport cargo from its origin to its final destination.

Ontology-enriched Visualization of Human Anatomy  

SciTech Connect

The project focuses on the problem of presenting a human anatomical 3D model associated with other types of human systemic information ranging from physiological to anatomical information while navigating the 3D model. We propose a solution that integrates a visual 3D interface and navigation features with the display of structured information contained in an ontology of anatomy where the structures of the human body are formally and semantically linked. The displayed and annotated anatomy serves as a visual entry point into a patient's anatomy, medical indicators and other information. The ontology of medical information provides labeling to the highlighted anatomical parts in the 3D display. Because of the logical organization and links between anatomical objects found in the ontology and associated 3D model, the analysis of a structure by a physician is greatly enhanced. Navigation within the 3D visualization and between this visualization and objects representing anatomical concepts within the model is also featured.

Hypertools in image and volume visualization  

SciTech Connect

This paper describes our experience in image and volume visualization at the Lawrence Livermore National Laboratory. After an introduction on visualization issues, we present a new software approach to the analysis and visualization of images and volumes. The efficiency of the visualization process is improved by letting the user combine small and reusable applications by the means of a machine-independent interpreted language such as Tcl/Tk. These hypertools can communicate with each other over a network, which has a direct impact on the design of graphical interfaces. We first describe the implementation of a flexible gray-scale image widget that can handle large data sets, provides complete control of the color palette and allows for manual and semi-interactive segmentation. This visualization tool can be embedded in a data-flow image processing environment to assess the quality of acquisition, preprocessing and filtering of raw data. This approach combines the simplicity of visual programming with the power of a high-level interpreted language. We show how hypertools can be used in surface and volume rendering and how they increase the interaction efficiency by performing complex or tedious tasks automatically. One biomedical application is presented.

Visualization requires high performance computers. In order to use these shared high performance computers located at national centers, the authors need an environment for remote visualization. Remote visualization is a special process that uses computing resources and data that are physically distributed over long distances. In their experimental environment, a parallel raytracer is designed for the rendering task. It allows one to efficiently visualize molecular dynamics simulations represented by three dimensional ball-and-stick models. Different issues encountered in creating their platform are discussed, such as I/O, load balancing, and data distribution.

High contrast, CdTe portal scanner for radiation therapy  

Science Conference Proceedings (OSTI)

This paper reports on one of the most promising new technologies for improving the qualify of radiation therapy, the use of real-time systems to produce portal images. In the authors' approach, they are constructing a linear array of 256 CdTe photovoltaic detectors attached to a very compact linear scanner, all of which will be mounted in a cassette shaped package to be located under the patient table. The high stopping power of the CdTe allows a high contrast image to be made using only a single Linac pulse per line, resulting in a high contrast image in under 5 seconds.

A New Tool for Effective and Efficient Project Management  

SciTech Connect

Organizations routinely handle thousands of projects per year, and it is difficult to manage all these projects concurrently. Too often, projects do not get the attention they need when they need it. Management inattention can lead to late projects or projects with less than desirable content and/or deliverables. This paper discusses the application of Visual Project Management (VPM) as a method to track and manage projects. The VPM approach proved to be a powerful management tool without the overhead and restrictions of traditional management methods.

Geospatial Visualization of Global Satellite Images with Vis-EROS  

SciTech Connect

The Earth Resources Observation and Science (EROS) Center of U.S. Geological Survey is currently managing and maintaining the world largest satellite images distribution system, which provides 24/7 free download service for researchers all over the globe in many areas such as Geology, Hydrology, Climate Modeling, and Earth Sciences. A large amount of geospatial data contained in satellite images maintained by EROS is generated every day. However, this data is not well utilized due to the lack of efficient data visualization tools. This software implements a method for visualizing various characteristics of the global satellite image download requests. More specifically, Keyhole Markup Language (KML) files are generated which can be loaded into an earth browser such as Google Earth. Colored rectangles associated with stored satellite scenes are painted onto the earth browser; and the color and opacity of each rectangle is varied as a function of the popularity of the corresponding satellite image. An analysis of the geospatial information obtained relative to specified time constraints provides an ability to relate image download requests to environmental, political, and social events.

Grating Based, Phase Contrast Radiography with Bremsstrahlung Source  

SciTech Connect

Phase-contrast radiography (PCR) generates an image from gradients in the phase of the probing X-radiation induced by the radiographic object, and can therefore make visible features difficult or impossible to see with conventional, absorption-contrast (ACR) radiography. For any particular object, variations in either the real or imaginary parts of the index of refraction could be greater. Most practical difficulties of PCR arise from the very small deviation from unity (~10-5-10-6, depending of material and energy) of the real part of the index of refraction. In principal, straightforward shadowgraphy would provide a phase-contrast image, but in practice this is usually overwhelmed by the zero-order (bright field) signal. Eliminating this sets the phase-contrast signal against a dark field (as in Schlieren photography with visible light). One way to do this with X-rays is with a grating that produces a Talbot interference pattern. Minute variations in optical path lengths through the radiographic object can significantly shift the Talbot fringes, and these shifts constitute a dark-field signal separate from the zero-order wave. This technique has recently been investigated up to ~20keV [1-3]; this work addresses what sets the practical upper limit, and where that limit is. These appear to be grating fabrication, and ~60keV, respectively.

Collaborative Visualization for Large-Scale Accelerator Electromagnetic Modeling (Final Report)  

Science Conference Proceedings (OSTI)

This report contains the comprehensive summary of the work performed on the SBIR Phase II, Collaborative Visualization for Large-Scale Accelerator Electromagnetic Modeling at Kitware Inc. in collaboration with Stanford Linear Accelerator Center (SLAC). The goal of the work was to develop collaborative visualization tools for large-scale data as illustrated in the figure below. The solutions we proposed address the typical problems faced by geographicallyand organizationally-separated research and engineering teams, who produce large data (either through simulation or experimental measurement) and wish to work together to analyze and understand their data. Because the data is large, we expect that it cannot be easily transported to each team member's work site, and that the visualization server must reside near the data. Further, we also expect that each work site has heterogeneous resources: some with large computing clients, tiled (or large) displays and high bandwidth; others sites as simple as a team member on a laptop computer. Our solution is based on the open-source, widely used ParaView large-data visualization application. We extended this tool to support multiple collaborative clients who may locally visualize data, and then periodically rejoin and synchronize with the group to discuss their findings. Options for managing session control, adding annotation, and defining the visualization pipeline, among others, were incorporated. We also developed and deployed a Web visualization framework based on ParaView that enables the Web browser to act as a participating client in a collaborative session. The ParaView Web Visualization framework leverages various Web technologies including WebGL, JavaScript, Java and Flash to enable interactive 3D visualization over the web using ParaView as the visualization server. We steered the development of this technology by teaming with the SLAC National Accelerator Laboratory. SLAC has a computationally-intensive problem important to the nations scientific progress as described shortly. Further, SLAC researchers routinely generate massive amounts of data, and frequently collaborate with other researchers located around the world. Thus SLAC is an ideal teammate through which to develop, test and deploy this technology. The nature of the datasets generated by simulations performed at SLAC presented unique visualization challenges especially when dealing with higher-order elements that were addressed during this Phase II. During this Phase II, we have developed a strong platform for collaborative visualization based on ParaView. We have developed and deployed a ParaView Web Visualization framework that can be used for effective collaboration over the Web. Collaborating and visualizing over the Web presents the community with unique opportunities for sharing and accessing visualization and HPC resources that hitherto with either inaccessible or difficult to use. The technology we developed in here will alleviate both these issues as it becomes widely deployed and adopted.

NV: Nessus Vulnerability Visualization for the Web  

SciTech Connect

Network vulnerability is a critical component of network se- curity. Yet vulnerability analysis has received relatively lit- tle attention from the security visualization community. In this paper we describe nv, a web-based Nessus vulnerability visualization. Nv utilizes treemaps and linked histograms to allow system administrators to discover, analyze, and man- age vulnerabilities on their networks. In addition to visual- izing single Nessus scans, nv supports the analysis of sequen- tial scans by showing which vulnerabilities have been fixed, remain open, or are newly discovered. Nv was also designed to operate completely in-browser, to avoid sending sensitive data to outside servers. We discuss the design of nv, as well as provide case studies demonstrating vulnerability analysis workflows which include a multiple-node testbed and data from the 2011 VAST Challenge.

Visual Specification of Complex Database Actions  

E-Print Network (OSTI)

The paper presents an approach to specify in an integrated way by visual, diagrammatic languages the structural and behavioural aspects of database applications. Hereby, well-known extended Entity-Relationship diagrams are employed to specify the structural aspects. The behavioural aspects of a database application are specified by using ViAL (Visual Action Language). ViAL specifications are a special kind of data (or better object) flow diagrams, where so-called elementary actions are used as basic building blocks. These elementary actions are automatically derived from a given EER diagram. They guarantee that after finishing their execution all inherent integrity constraints are fulfilled. The paper explains the features of the language ViAL and gives some illustrating examples. 1 Introduction Nowadays, semantic data models are regarded as convenient means to specify database applications [11]. Most of these approaches offer corresponding visual specification languages which eases b...

Variable Interactions in Query-Driven Visualization  

SciTech Connect

One fundamental element of scientific inquiry is discoveringrelationships, particularly the interactions between different variablesin observed or simulated phenomena. Building upon our prior work in thefield of Query-Driven Visualization, where visual data analysisprocessing is focused on subsets of large data deemed to be"scientifically interesting," this new work focuses on a novel knowledgediscovery capability suitable for use with petascale class datasets. Itenables visual presentation of the presence or absence of relationships(correlations) between variables in data subsets produced by Query-Drivenmethodologies. This technique holds great potential for enablingknowledge discovery from large and complex datasets currently emergingfrom SciDAC and INCITE projects. It is sufficiently generally to beapplicable to any time of complex, time-varying, multivariate data fromstructured, unstructured or adaptive grids.

Importance-driven compositing window management  

E-Print Network (OSTI)

In this paper we present importance-driven compositing window management, which considers windows not only as basic rectangular shapes but also integrates the importance of the windows content using a bottom-up visual attention model. Based on this information, importance-driven compositing optimizes the spatial window layout for maximum visibility and interactivity of occluded content in combination with see-through windows. We employ this technique for emerging window manager functions to minimize information overlap caused by popping up windows or floating toolbars and to improve the access to occluded window content. An initial user study indicates that our technique provides a more effective and satisfactory access to occluded information than the well-adopted Alt+Tab window switching technique and see-through windows without optimized spatial layout.

System and method for floating-substrate passive voltage contrast  

DOE Patents (OSTI)

A passive voltage contrast (PVC) system and method are disclosed for analyzing ICs to locate defects and failure mechanisms. During analysis a device side of a semiconductor die containing the IC is maintained in an electrically-floating condition without any ground electrical connection while a charged particle beam is scanned over the device side. Secondary particle emission from the device side of the IC is detected to form an image of device features, including electrical vias connected to transistor gates or to other structures in the IC. A difference in image contrast allows the defects or failure mechanisms be pinpointed. Varying the scan rate can, in some instances, produce an image reversal to facilitate precisely locating the defects or failure mechanisms in the IC. The system and method are useful for failure analysis of ICs formed on substrates (e.g. bulk semiconductor substrates and SOI substrates) and other types of structures.

Rectangular-Mask Coronagraphs for High-Contrast Imaging  

E-Print Network (OSTI)

We present yet another new family of masks for high-contrast imaging as required for the to-be-built terrestrial planet finder space telescope. The ``best'' design involves a square entrance pupil having a 4-vane spider, a square image-plane mask containing a plus-sign shaped occulter to block the starlight inside 0.6 lambda/D, and a Lyot-plane mask consisting of a rectangular array of rectangular opennings. Using Fraunhofer analysis, we show that the optical system can image a planet 10^{-10} times as bright as an on-axis star in four rectangular regions given by {(xi,zeta): 1.4 stripes of opaque material with the stripes oriented at right angles to each other. We call these striped masks barcode masks. We show that it is sufficient for the barcode masks by themselves to provide 10^{-5} contrast. This then guarantees that the full system will provide the required 10^{-10} contrast.

Developing Guidelines for Assessing Visual Analytics Environments  

SciTech Connect

Visual analytic systems can be evaluated from a user perspective with quantitative metrics (i.e., time to complete the analysis or the accuracy of the solution found). However, qualitative measures are also useful in a user assessment. These include such measures as the utility of the interactive visualizations in the analysis process and the user's assessment of the efficiency of the analytic process. Quantitative measures can be found if data sets with embedded ground truth are used for analysis. Qualitative measures are more elusive. In this paper we report on an experiment with professional analysts who ranked five of submissions to the VAST 2009 Challenge and provided the rationale for their rankings. Their comments were used in conjunction with a meta-analysis of the 2009 VAST Challenge reviews to produce a set of guidelines for visual analytic systems. As visual analytic software is expected to eventually help in all aspects of analysis, we expect to see future systems provide more help with generating the final report. Hence, researchers also need to have an understanding of what makes a good analytic product. Therefore we asked the analysts to rank the situational assessments of four grand challenge entries and to provide comments on those assessments. We used these comments to produce guidelines for researchers to use in evaluating their analytic reports.

A Visual Agent for Performance Graphics  

E-Print Network (OSTI)

Visual Agents are software entities which assist people in performing graphical tasks. One useful and interesting graphical task is to make a textand -graphic record of a group meeting. When the recording is done live in view of the group on a large display, such as on a whiteboard, it is a performing art which can be called "Group Graphics. " During group graphics, collaboration is enhanced because the group members can see the record as it is being made, offering suggestions and corrections. And if graphic recording of this kind takes place on a large computer display, then visual agents can be brought into play. Presented in this paper is a visual agent which acts as a whiteboard assistant for group graphics, helping a person to graphically record the conversation and concepts of a working group on a large display. 1 Context: Performance Text-Graphics on the Big Screen The long term goal of this work has been to construct a visual medium which will support the improvisational crea...

To ensure contractors establish, document, and maintain adequate purchasing systems. 2. To ensure contractors flow down contract requirements to subcontractors. WHY IS SUBCONTRACT MANAGEMENT IMPORTANT? In many Department prime contracts a significant portion of the obligated dollars is spent on subcontract work. Due to the absence of a direct contractual relationship with the subcontractor, the Department must rely on the prime contractor to manage subcontract work. Subcontractors perform significant work efforts at sites and are an integral part of the site's success. Prime

A Coprocessor for Accelerating Visual Information Processing  

E-Print Network (OSTI)

Visual information processing will play an increasingly important role in future electronics systems. In many applications, e.g. video surveillance cameras, data throughput of microprocessors is not sufficient and power consumption is too high. Instruction profiling on a typical test algorithm has shown that pixel address calculations are the dominant operations to be optimized. Therefore AddressLib, a structured scheme for pixel addressing was developed, that can be accelerated by AddressEngine, a coprocessor for visual information processing. In this paper, the architectural design of AddressEngine is described, which in the first step supports a subset of the AddressLib. Dataflow and memory organization are optimized during architectural design. AddressEngine was implemented in a FPGA and was tested with MPEG-7 Global Motion Estimation algorithm. Results on processing speed and circuit complexity are given and compared to a pure software implementation. The next step will be the support for the full Addres...

A Stereographic Visualization Environment and its Applications  

SciTech Connect

The data visualization activity at Brookhaven National Laboratory is rooted in programs extending back several decades to develop, evaluate and deploy imaging instruments. Several of these developments, such as Magnetic Resonance Imaging (MRI) and Positron Emission Tomography (PET) technology, were targeted for medical imaging. Other applications made use of images derived from larger, general purpose scientific instruments such as the Laboratory's nuclear reactors and particle accelerators. The most recent impetus to the program has been from a cooperative research and development project between BNL and two industrial companies, GTE and Mobil Oil involving microtomographic imaging of oil reservoir rock, which included development of a novel stereoscopic visualization theatre. This 'Vis Theatre' has been subsequently used for research in other scientific disciplines, and has attracted considerable attention in both the technical literature and even the popular press.

Visualizing Energy Resources Dynamically on Earth  

Science Conference Proceedings (OSTI)

For the North American hurricane season, in partnership with the Tennessee Valley Authority (TVA) and working with the U.S. Department of Energy, Office of Electricity Delivery and Energy Reliability, we have developed a capability that helps visualize the status of the electric transmission system infrastructure. The capability toolkit, called VERDE - Visualizing Energy Resources Dynamically on Earth, takes advantage of the Google Earth platform to display spatiotemporally informed power grid and related data. Custom libraries describe the electrical transmission network in the Eastern United States and the dynamic status of each transmission line. Standard Google Earth layers provide additional spatial context. In addition to live status, VERDE provides a framework and mechanism to ingest and intuitively present predictive models, data from different sources, and response needs.

Visualization of salt-induced stress perturbations.  

Science Conference Proceedings (OSTI)

An important challenge encountered during post-processing of finite element analyses is the visualizing of three-dimensional fields of real-valued second-order tensors. Namely, as finite element meshes become more complex and detailed, evaluation and presentation of the principal stresses becomes correspondingly problematic. In this paper, we describe techniques used to visualize simulations of perturbed in-situ stress fields associated with hypothetical salt bodies in the Gulf of Mexico. We present an adaptation of the Mohr diagram, a graphical paper and pencil method used by the material mechanics community for estimating coordinate transformations for stress tensors, as a new tensor glyph for dynamically exploring tensor variables within three-dimensional finite element models. This interactive glyph can be used as either a probe or a filter through brushing and linking.

Target Visualization at the National Ignition Facility  

SciTech Connect

As the National Ignition Facility continues its campaign to achieve ignition, new methods and tools will be required to measure the quality of the targets used to achieve this goal. Techniques have been developed to measure target surface features using a phase-shifting diffraction interferometer and Leica Microsystems confocal microscope. Using these techniques we are able to produce a detailed view of the shell surface, which in turn allows us to refine target manufacturing and cleaning processes. However, the volume of data produced limits the methods by which this data can be effectively viewed by a user. This paper introduces an image-based visualization system for data exploration of target shells at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory. It aims to combine multiple image sets into a single visualization to provide a method of navigating the data in ways that are not possible with existing tools.

Topological Cacti: Visualizing Contour-based Statistics  

SciTech Connect

Contours, the connected components of level sets, play an important role in understanding the global structure of a scalar field. In particular their nestingbehavior and topology-often represented in form of a contour tree-have been used extensively for visualization and analysis. However, traditional contour trees onlyencode structural properties like number of contours or the nesting of contours, but little quantitative information such as volume or other statistics. Here we use thesegmentation implied by a contour tree to compute a large number of per-contour (interval) based statistics of both the function defining the contour tree as well asother co-located functions. We introduce a new visual metaphor for contour trees, called topological cacti, that extends the traditional toporrery display of acontour tree to display additional quantitative information as width of the cactus trunk and length of its spikes. We apply the new technique to scalar fields ofvarying dimension and different measures to demonstrate the effectiveness of the approach.

Automated visual direction : LDRD 38623 final report.  

Science Conference Proceedings (OSTI)

Mobile manipulator systems used by emergency response operators consist of an articulated robot arm, a remotely driven base, a collection of cameras, and a remote communications link. Typically the system is completely teleoperated, with the operator using live video feedback to monitor and assess the environment, plan task activities, and to conduct the operations via remote control input devices. The capabilities of these systems are limited, and operators rarely attempt sophisticated operations such as retrieving and utilizing tools, deploying sensors, or building up world models. This project has focused on methods to utilize this video information to enable monitored autonomous behaviors for the mobile manipulator system, with the goal of improving the overall effectiveness of the human/robot system. Work includes visual servoing, visual targeting, utilization of embedded video in 3-D models, and improved methods of camera utilization and calibration.

The goals of this research include developing and identifying software technologies, which facilitate the use of buildings described in Building Information Modeling (BIM) tools in both a simulation and visualization. The study focused on the development of a tool to fulfill the visualization needs of a Visual Energy Use System. To accomplish this, the study identified an open BIM file standard, the Industry Foundation Classes (IFC). The study also identified a video game based 3D virtual environment, the Doom 3 Engine. A tool developed during the study, IFCtoMAP, converts IFC data into the .MAP file format understood by the Doom 3 Engine. Finally, the study identified the IFCtoIDF utility, which translates IFC data into a format understood by the building energy simulation program EnergyPlus. Data from the Building Information Modeling tool Revit Building exports to the .IFC file format, which in turn drives the two conversion utilities IFCtoMAP and IFCtoIDF. The output of the IFCtoIDF tool consists of an .IDF file that EnergyPlus uses to perform an energy simulation. The output of the IFCtoMAP tool consists of a .MAP file, which the Doom 3 game engine uses to display three dimensional first person perspective visualization. The result of the study was the successful creation of an automated tool that converts building geometry found in .IFC files into the .MAP file format understood by Doom 3 game engine. This document details the methods employed by the IFCtoMAP software along with a brief discussion of the IFCtoIDF conversion utility.

APPLYING SIMPLE TECHNOLOGY ACCOMPLISHES VISUAL INSPECTION CHALLENGES  

SciTech Connect

This paper discusses the successful implementation of simple video technologies at the Savannah River Site (SRS) to perform complex visual inspection, monitoring, and surveillance tasks. Because SRS facilities are similar to those of an industrial plant, the environmental and accessibility considerations for remote viewing are the primary determining factors in the selection of technology. The constraints and challenges associated with remote viewing are discussed, and examples of applications are given.

Visual Analytics for Roof Savings Calculator Ensembles  

SciTech Connect

The Roof Savings Calculator (RSC) has been deployed for DOE as an industry-consensus, web-based tool for easily running complex building energy simulations. These simulations allow both homeowners and experts to determine building-specific cost and energy savings for modern roof and attic technologies. Using a database of over 3 million RSC simulations for different combinations of parameters, we have built a visual analytics tool to assist in the exploration and identification of features in the data. Since the database contains multiple variables, both categorical and continuous, we employ a coordinated multi-view approach that allows coordinated feature exploration through multiple visualizations at once. The main component of our system, a parallel coordinates view, has been adapted to handle large-scale, mixed data types as are found in RSC simulations. Other visualizations include map coordinated plots, high dynamic range (HDR) line plot rendering, and an intuitive user interface. We demonstrate these techniques with several use cases that have helped identify software and parametric simulation issues.

Mobile visual examination and repackaging (MOVER) system  

SciTech Connect

Process engineering and waste technology teams at LOS Alamos National Laboratory delivered a prototype Mobile Visual Examination and Repackaging (MOVER) system to the Waste Isolation Pilot Plant (WIPP) outside of Carlsbad, NM in October, 2000. This system was developed in response to compliance issues with legacy waste that was packaged in 55 gallons drums prior to release of WIPP's waste acceptance criteria (WAC). A statistical percentage of these 55 gallon drums will be opened and visually examined (VE) as part of re-characterization using Non-destructive examination (NDE) procedures. VE is an intrusive technique since the drum is opened, and as a result, there are more risks in spreading contamination. Hence, VE is performed in a glovebox to protect the workers and the environment. During VE, waste is pulled out of one drum, visually examined, the amount of plutonium measured if necessary, and the waste repackaged into one or more drums. MOVER can perform all these operations, along with having the capability to house the glovebox operations and all support equipment in a 40-foot-long container that can be transported to a site on a semi-trailer. This container is divided into three rooms, providing the level of safety and containment of a fixed facility. A key asset of mobile systems is the inherent need for modular design that reduces infrastructure costs and overhead. A mobile system like MOVER represents a technology base aimed at meeting DOE schedules to accelerate decommissioning of many sites.

Measurements of Surface Heat Flux Measurements of Surface Heat Flux Over Contrasting Surfaces R. L. Coulter J. D. Shannon T. J. Martin Argonne National Laboratory Argonne, IL 60439 In a multilaboratory field study held near Boardman in northeastern Oregon in June 1991 and described in greater detail elsewhere (Doran et al. 1991), various properties of the surface and lower atmospheric boundary layer over heavily irrigated cropland and adjacent desert steppe were investigated. The locale was selected because its disparate characteristics over various spatial scales stress the ability of general circulation models (GCMs) to describe lower boundary conditions, particularly across the discontinuity between desert (in which turbulent flux of heat must be primarily as sensible heat) and large irrigated tracts (in which turbulent flux of latent heat should be the larger term).

Hard X-ray Phase-Contrast Tomographic Nanoimaging  

Science Conference Proceedings (OSTI)

Synchrotron-based full-field tomographic microscopy established itself as a tool for noninvasive investigations. Many beamlines worldwide routinely achieve micrometer spatial resolution while the isotropic 100-nm barrier is reached and trespassed only by few instruments, mainly in the soft x-ray regime. We present an x-ray, full-field microscope with tomographic capabilities operating at 10 keV and with a 3D isotropic resolution of 144 nm recently installed at the TOMCAT beamline of the Swiss Light Source. Custom optical components, including a beam-shaping condenser and phase-shifting dot arrays, were used to obtain an ideal, aperture-matched sample illumination and very sensitive phase-contrast imaging. The instrument has been successfully used for the nondestructive, volumetric investigation of single, unstained cells.

Visualization of manhole and precursor-type events for the Manhattan electrical distribution system  

E-Print Network (OSTI)

We present a visualization framework for analyzing the Consolidated Edison Company of New York (Con Edison) trouble tickets for the Manhattan electrical distribution system. The Con Edison Emergency Control System (ECS) is a work management tool that documents all events that occur in the electrical distribution system. The trouble ticket generated from ECS is a record of an event affecting the secondary (low-voltage) electrical distribution system, such as a manhole fire, manhole explosion, smoking manhole, no-light event, flickering light event, side-off partial outage, or burnout. The visualization tool outlined here is used alongside our preliminary statistical and machine learning work for predicting future manhole events. ECS tickets stored in our PostgreSQL database are displayed using Google Earths satellite images of Manhattan as a backdrop. The ability of this tool to display events relative to the surrounding buildings has already yielded some highly promising directions for our ongoing analysis.

IN-VIVO EXPOSURE CHARACTERIZATION AND VISUALIZATION OF SWNH AGGREGATES  

DOE Green Energy (OSTI)

As the manufacturing and use of nanomaterials and nanoparticle clusters/aggregates become prevalent in the future, it will be necessary to understand the biological interactions with this new class of materials introduced through various routes, intentionally or unintentionally. However, there currently exist a host of technical/methodological issues related to nanotoxicological study. For example, the ability to generate reproducible precision nanomaterial and nanoparticles is critically needed for both toxicological evaluation and pharmaceutical applications. Technology for tracing and visualization of nanomaterials in biological systems are also lacking. Single-walled carbon nanohorn (SWNH) is a unique carbon nanostructure belonging to the same family as the famous carbon nanotubes. SWNH aggregates can be produced through laser vaporization of carbon at room temperature; the aggregates are of particular interest to energy application such as hydrogen storage and new-generation of fuel cells. Unlike carbon nanotubes that are made using metal catalysts, SWNHs can be made without the use of a metal catalyst providing an opportunity for nanotoxicological study of purest carbon nanoparticles with no complication of trace metal toxicity that the nanotubes might have. We summarize results from our ongoing biological research on SWNHs. Our results were from in vivo animal aspiration experiments, in contrast to the results of a recent publication that were based on phenotypic observation of cell-line exposure experiments. The characterization results of ORNL-produced SWNHs are presented in Figure 1, which include low- (Figure 1a) and high-resolution (Figure 1b) structural images of SWNHs, the thermal gravimetric analysis (Figure 1c) and characteristic Raman (Figure 1d) results. We coated the SWNH powder with Pluronic F-127, which is a biocompatible polymer, to facilitate the dispersion of SWNHs in suspension during pressure-driven nebulization in mice aspiration and nose-only inhalation experiments. The phenotypic and genomic expression results are reported by. Twenty-two inflammatory measures from bronchoalveolar lavage were assayed. Only five showed significant changes from the control (e.g., G-CSF, GM-CSF, IP-10, and IL-5) in 24 hours after exposure indicating acute inflammatory responses; however, the responses subsided in 7 days and no significant difference could be found between the control and exposed groups. Whole lung microarray analysis also found few differences between SWNH-exposed and controls of several genes in 24 hours. The SWNH aggregates did penetrate cell membranes; the stained optical microscopy images show the presence of SWNH aggregates in mice red blood cell. The images results are consistent with visualization by using the Scanning Near Field Ultrasound Holography (SNFUH) available at the Oak Ridge National Laboratory. The SNFUH also provided transport information regarding the transport dynamics of the SWNH aggregates into the cells. The visualization showing consistent results with those obtained from the stained optical microscopy.

Advanced visualization techniques can be used to investigate gamma ray and neutron dose rates around complex dose rate intensive operations. A method has been developed where thousands of dose points are calculated using the MCNP(Monte Carlo N-Particle) computer code and then displayed to create color contour plots of the dose rate for complex geometries. Once these contour plots are created, they are sequenced together creating an animation to dynamically show how the dose rate changes with changes in the geometry or source over time.

MANAGEMENT SUMMARY  

E-Print Network (OSTI)

need to effectively manage business performance. This has never been more true than in todays complex, highly regulated and confusing business environment which requires better decisions and improved execution now! In spite of the billions of dollars invested in infor-mation technology to address these challenges, managers and executives in many organizations still make key decisions underpinned by their own personal versions of documents and spread-sheets. Their organization struggles to provide a seamless flow of trusted information between customers, suppliers and their employees. The result is that most organizations cannot provide their people with the right information at the right time, and in attempting to do so are committing significant resources to compiling and auditing numbers instead of using them to inform the business. Consequently, they are far more reac-tive than proactive and ultimately they are not efficiently and effectively managing their current and future performance. Leading organizations are investing in managing information and developing predictive insights to drive sustainable business results. These com-panies have become masters in Performance Management- going beyond mere users of business intelligence to become the Intelligent Enterprises. ...a new breed of company is upping the stakes....have dominated their fields by deploy-ing industrial-strength analytics across a wide variety of activities. In essence, they are trans-forming their organiza-tions into armies of killer apps and crunching their way to victory.

Visualization Tools for Lattice QCD - Final Report  

Science Conference Proceedings (OSTI)

Our research project is about the development of visualization tools for Lattice QCD. We developed various tools by extending existing libraries, adding new algorithms, exposing new APIs, and creating web interfaces (including the new NERSC gauge connection web site). Our tools cover the full stack of operations from automating download of data, to generating VTK #12;files (topological charge, plaquette, Polyakov lines, quark and meson propagators, currents), to turning the VTK #12;files into images, movies, and web pages. Some of the tools have their own web interfaces. Some Lattice QCD visualization have been created in the past but, to our knowledge, our tools are the only ones of their kind since they are general purpose, customizable, and relatively easy to use. We believe they will be valuable to physicists working in the #12;field. They can be used to better teach Lattice QCD concepts to new graduate students; they can be used to observe the changes in topological charge density and detect possible sources of bias in computations; they can be used to observe the convergence of the algorithms at a local level and determine possible problems; they can be used to probe heavy-light mesons with currents and determine their spatial distribution; they can be used to detect corrupted gauge configurations. There are some indirect results of this grant that will benefit a broader audience than Lattice QCD physicists.

From Question Answering to Visual Exploration  

SciTech Connect

Research in Question Answering has focused on the quality of information retrieval or extraction using the metrics of precision and recall to judge success; these metrics drive toward finding the specific best answer(s) and are best supportive of a lookup type of search. These do not address the opportunity that users? natural language questions present for exploratory interactions. In this paper, we present an integrated Question Answering environment that combines a visual analytics tool for unstructured text and a state-of-the-art query expansion tool designed to compliment the cognitive processes associated with an information analysts work flow. Analysts are seldom looking for factoid answers to simple questions; their information needs are much more complex in that they may be interested in patterns of answers over time, conflicting information, and even related non-answer data may be critical to learning about a problem or reaching prudent conclusions. In our visual analytics tool, questions result in a comprehensive answer space that allows users to explore the variety within the answers and spot related information in the rest of the data. The exploratory nature of the dialog between the user and this system requires tailored evaluation methods that better address the evolving user goals and counter cognitive biases inherent to exploratory search tasks.

Capturing and Using Knowledge about the Use of Visualization Toolkits  

Science Conference Proceedings (OSTI)

When constructing visualization pipelines using toolkits such as Visualization Toolkit (VTK) and Generic Mapping Tools (GMT), developers must understand (1) what toolkit operators will transform their data from its raw state to some required view state and (2) what viewers are available to present the generated view. Traditionally, developers learn about how to construct visualization pipelines by reading documentation and inspecting code examples, which can be costly in terms of the time and effort expended. Once an initial pipeline is constructed, developers may still have to undergo a trial and error process before a satisfactory visualization is generated. This paper presents the Visualization Knowledge Project (VisKo) that is built on a knowledge base of visualization toolkit operators and how they can be piped together to form visualization pipelines. Developers may now rely on VisKo to guide them when constructing visualization pipelines and in some cases, when VisKo has complete knowledge about some set of operators (i.e., sequencing and parameter settings), automatically generate a fully functional visualization pipeline.

VISMASHUP: streamlining the creation of custom visualization applications  

SciTech Connect

Visualization is essential for understanding the increasing volumes of digital data. However, the process required to create insightful visualizations is involved and time consuming. Although several visualization tools are available, including tools with sophisticated visual interfaces, they are out of reach for users who have little or no knowledge of visualization techniques and/or who do not have programming expertise. In this paper, we propose VISMASHUP, a new framework for streamlining the creation of customized visualization applications. Because these applications can be customized for very specific tasks, they can hide much of the complexity in a visualization specification and make it easier for users to explore visualizations by manipulating a small set of parameters. We describe the framework and how it supports the various tasks a designer needs to carry out to develop an application, from mining and exploring a set of visualization specifications (pipelines), to the creation of simplified views of the pipelines, and the automatic generation of the application and its interface. We also describe the implementation of the system and demonstrate its use in two real application scenarios.

Ignition may happen in the middle or displaced slightly to one side, but this simulation explores the consequences of central ignition. In a localized hot spot, represented here by a deformed sphere with an average radius of 100 km, carbon is assumed to have already fused to iron, producing hot ash (~10 billion K) with a density about 20% less than its surroundings. As the burning progresses, this hot buoyant ash rises up and interacts with cold fuel. Rayleigh-Taylor fingers give rise to shear and turbulence, which interacts with the flame, causing it to move faster. In about 2 seconds, the energy released blows the entire white dwarf star up,

Understanding visual preferences for landscapes: an examination of the relationship between aesthetics and emotional bonding  

E-Print Network (OSTI)

The relationship between humans and the quality of the environment have been examined primarily through two conceptual constructs: landscape aesthetics and place attachment or emotional place bonding. The former focuses on the physical environment and the latter focuses on the emotional or symbolic environment. This study focused on understanding the relationship between the two constructs, and provided a framework to integrate them toward a more comprehensive visual preference for landscapes. Nasars (1989) symbolic model was used as a guiding concept in the study. A web-based survey was used to collect peoples responses to landscapes portrayed in photographs. Four primary measures were used in the survey: landscape aesthetic, typicality (to a national park), emotional place bonding, and landscape visual preference. To further examine the effect of place meaning on responses to landscapes, respondents were told during the survey that landscape pictures were taken from different places, which were assigned randomly as place labels (national park, commercial recreation area, local park, and scenic area). Results indicated that emotional place bonding was significantly and positively influenced by perceived landscape aesthetics through four components: complexity, mystery, coherence, and legibility. Complexity and mystery had more influence on emotional place bonding than the other two components. Results also provided empirical support for Nasars (1989) symbolic model. The effect of landscape aesthetics on landscape visual preference was partially mediated by typicality and emotional place bonding. The typicality of a scene to a national park was found to positively influence peoples emotional bonding to the place. The four randomly assigned place labels did not elicit significantly different preferences or emotional responses to the places. This study documented how landscape aesthetics and emotional bonding can be integrated into visual preferences for landscapes. Results also provided evidence for the potential to use emotional bonding information to manage physical landscapes. The study contributes to our understanding and can assist with environment planning and management. Both physical appearance and symbolic/emotional meaning are very important to human perceptions of landscapes, and other attempts should be made to understand how the two constructs contribute to visual preference in future research.

The Development of Quality Assurance and Visualization for Safety Assessment System  

Science Conference Proceedings (OSTI)

Site Information and Total Environmental data management System (SITES) is an integrated program for overall data acquisition, environmental monitoring, and safety analysis. SITES is composed of three main modules such as site database system, safety assessment system and environmental monitoring system named SECURE, SAINT and SUDAL, respectively. SAINT abbreviated for Safety Assessment Integration system is the integrated interface for the radioactive waste safety assessment codes in the SITES. SAINT is developed for the application and analysis of data from SECURE and for the systematic management of the resulted data from the safety assessment. The Quality Assurance module in SAINT is implemented to enhance the reliability of safety assessment results. The visualization in SAINT is purposed of reliability, comprehension of safety assessment results and user's convenience which can easily recognize the assessment results using the geographic information.

The dynamics of individual nucleosomes controls the chromatin condensation pathway: direct AFM visualization of variant chromatin  

E-Print Network (OSTI)

Chromatin organization and dynamics is studied in this work at scales ranging from single nucleosome to nucleosomal array by using a unique combination of biochemical assays, single molecule imaging technique and numerical modeling. We demonstrate that a subtle modification in the nucleosome structure induced by the histone variant H2A.Bbd drastically modifies the higher order organization of the nucleosomal arrays. Importantly, as directly visualized by AFM, conventional H2A nucleosomal arrays exhibit specific local organization, in contrast to H2A.Bbd arrays, which show ?beads on a string? structure. The combination of systematic image analysis and theoretical modeling allows a quantitative description relating the observed gross structural changes of the arrays to their local organization. Our results strongly suggest that higher-order organization of H1-free nucleosomal arrays is mainly determined by the fluctuation properties of individual nucleosomes. Moreover, numerical simulations suggest the existenc...

Visual Debugging of Visualization Software: A Case Study for Particle Systems  

SciTech Connect

Visualization systems are complex dynamic software systems. Debugging such systems is difficult using conventional debuggers because the programmer must try to imagine the three-dimensional geometry based on a list of positions and attributes. In addition, the programmer must be able to mentally animate changes in those positions and attributes to grasp dynamic behaviors within the algorithm. In this paper we shall show that representing geometry, attributes, and relationships graphically permits visual pattern recognition skills to be applied to the debugging problem. The particular application is a particle system used for isosurface extraction from volumetric data. Coloring particles based on individual attributes is especially helpful when these colorings are viewed as animations over successive iterations in the program. Although we describe a particular application, the types of tools that we discuss can be applied to a variety of problems.

Three-dimensional visualization of reactive flows in complex geometries  

SciTech Connect

The visualization of fluid flows has become more challenging, as recent advancements in computational methods have increased the complexity and size of simulations. Our objective is to develop a flexible flow visualization tool for fluid simulations that include the full physics and geometrical complexities found in modeling practical combustion systems, such as internal combustion engines. The challenges to flow visualization come from: (1) the large simulation output, especially when using massively parallel computers; (2) the increasingly complex geometries that include moving surfaces such as pistons and valves; (3) the complex physical phenomena in realistic problems of fuel injection, combustion fronts, boundary flows, and large scale turbulence; and (4) the numerical complexity of indirect addressing of computational elements, variable mesh connectivity, distorted elements, and moving meshes. We have developed a visualization program that addresses these complexities. The program was developed as a post-processor to the KIVA family of codes for reactive flow simulations. Because of the complexity of the KIVA codes, the visualization program is very versatile and applicable to any code with meshes of arbitrary hexahedrons. No comparable commercial visualization package could be found. To visualize the fluid flow, we use mass-less tracer particles that follow the movement of the fluid as determined from output files from the simulation. The movement of the tracer particles is based on a second-order spatial and temporal interpolation of the fluid velocities from successive simulation output files. The visualization program runs on a Silicon Graphics IRIS GTX workstation.

Spatio-temporal Visualization for Environmental Decision Support  

Science Conference Proceedings (OSTI)

Traditional visualization of earth surface features has been addressed through visual exploration, analysis, synthesis, and presentation of observable geospatial data. However, characterizing the changes in their observable and unobservable properties of geospatial features is critical for planning and policy formulation. Recent approaches are addressing modeling and visualization of the temporal dynamics that describe observed and/or predicted physical and socioeconomic processes using vast volumes of earth observation (imagery and other geophysical) data from remote sensor networks. This paper provides an overview of selected geospatial modeling and simulation, exploratory analysis of earth observation data, and high performance visualization research at Oak Ridge National Laboratory for developing novel data driven approaches for geospatial knowledge discovery and visualization relevant to environmental decision support.

Managing PCBs  

Science Conference Proceedings (OSTI)

Compliance with Environmental Protection Agency regulations for managing the polychlorinated biphenyls (PCBs) that were widely distributed in electrical equipment will be costly to the utility industry, estimated at over $5 billion over a ten-year period by the Electric Power Research Institute (EPRI). Most of the budget could be needed to identify and reclaim 2.5 million contaminated transformers. Three divisions are coordinating EPRI research efforts with those of other companies and utilities in the areas of detection, destruction, spill cleanup, disposal, and health effects. (DCK)

A Four Channel 250 MHz Visual Counter  

Science Conference Proceedings (OSTI)

A visual counter rated at 250 mhz. with a pulse-pair resolution of 2.6 nanoseconds for nuclear instrument module (NIM) signals has been designed. Pulse widths for NIM signals must be equal to or greater than 2 ns. The counter has a separate input for transistor-transistor logic (TTL) signals and for this logic level it operates at rates equal to or less than 190 mhz. TTL pulses must be greater than 4 ns. The design was implemented on a printed circuit card. Four of these cards were packaged into a single unit resulting in a four channel device that can be mounted into a 19 inch rack. Seven units were built; they are presently used in the experimental area and in the Main Control Room of the Bevalac. The counter accepts well defined NIM or TTL signals internally terminated with 50 ohms. All the controls and the signal input connectors are located on the front panel. An Overflow output, Gate, and Reset inputs are located on the back panel. The counters have 8 Light Emitting Diode digit displays which are 20.3 mm high with a viewing distance rating of 10 meters. Light filters are used for the LED displays greatly enhancing their visibility.

From Mesh Generation to Scientific Visualization:  

E-Print Network (OSTI)

Parallel supercomputing has typically focused on the inner kernel of scientific simulations: the solver. The front and back ends of the simulation pipeline---problem description and interpretation of the output---have taken a back seat to the solver when it comes to attention paid to scalability and performance, and are often relegated to offline, sequential computation. As the largest simulations move beyond the realm of the terascale and into the petascale, this decomposition in tasks and platforms becomes increasingly untenable. We propose an end-to-end approach in which all simulation components---meshing, partitioning, solver, and visualization---are tightly coupled and execute in parallel with shared data structures and no intermediate I/O. We present our implementation of this new approach in the context of octree-based finite element simulation of earthquake ground motion. Performance evaluation on up to 2048 processors demonstrates the ability of the end-toend approach to overcome the scalability bottlenecks of the traditional approach.

Guided Text Search Using Adaptive Visual Analytics  

SciTech Connect

This research demonstrates the promise of augmenting interactive visualizations with semi- supervised machine learning techniques to improve the discovery of significant associations and insights in the search and analysis of textual information. More specifically, we have developed a system called Gryffin that hosts a unique collection of techniques that facilitate individualized investigative search pertaining to an ever-changing set of analytical questions over an indexed collection of open-source documents related to critical national infrastructure. The Gryffin client hosts dynamic displays of the search results via focus+context record listings, temporal timelines, term-frequency views, and multiple coordinate views. Furthermore, as the analyst interacts with the display, the interactions are recorded and used to label the search records. These labeled records are then used to drive semi-supervised machine learning algorithms that re-rank the unlabeled search records such that potentially relevant records are moved to the top of the record listing. Gryffin is described in the context of the daily tasks encountered at the US Department of Homeland Security s Fusion Center, with whom we are collaborating in its development. The resulting system is capable of addressing the analysts information overload that can be directly attributed to the deluge of information that must be addressed in the search and investigative analysis of textual information.

Lee, and Robert D. Clear Call Number LBNL-4417E Abstract The objective of this study was to explore how calibrated high dynamic range (HDR) images (luminance maps) acquired in real world daylit environments can be used to characterize, evaluate, and compare visual comfort conditions of innovative facade shading and light-redirecting systems. Detailed (1536 x 1536 pixel) luminance maps were time-lapse acquired from two view positions in an unoccupied full scale testbed facility. These maps were analyzed using existing visual comfort metrics to quantify how innovative interior and exterior shading systems compare to conventional systems under real sun and sky conditions over a solstice-to-solstice test interval. The results provide a case study in the challenges and potential of methods of visualizing, evaluating and summarizing daily and seasonal variation of visual comfort conditions computed from large sets of image data.

Visualization of Force Fields in Protein StructurePrediction  

SciTech Connect

The force fields used in molecular computational biology are not mathematically defined in such a way that their mathematical representation would facilitate the straightforward application of volume visualization techniques. To visualize energy, it is necessary to define a spatial mapping for these fields. Equipped with such a mapping, we can generate volume renderings of the internal energy states in a molecule. We describe our force field, the spatial mapping that we used for energy, and the visualizations that we produced from this mapping. We provide images and animations that offer insight into the computational behavior of the energy optimization algorithms that we employ.

Querying for Feature Extraction and Visualization in Climate Modeling  

SciTech Connect

The ultimate goal of data visualization is to clearly portray features relevant to the problem being studied. This goal can be realized only if users can effectively communicate to the visualization software what features are of interest. To this end, we describe in this paper two query languages used by scientists to locate and visually emphasize relevant data in both space and time. These languages offer descriptive feedback and interactive refinement of query parameters, which are essential in any framework supporting queries of arbitrary complexity. We apply these languages to extract features of interest from climate model results and describe how they support rapid feature extraction from large datasets.

Visualization of High Resolution Spatial Mass Spectrometric Data during Acquisition  

Science Conference Proceedings (OSTI)

Mass Spectrometric Imaging (IMS) allows the generation of 2D ion density maps that help visualize molecules present in sections of tissues and cells. The combination of spatial and mass resolution results in large and complex data sets that require powerful and efficient analysis and interpretation. In this paper, a graphical user interface (GUI) that can visualize the large data during data acquisition itself is presented. The program also has the ability to perform processing and analysis of the dataset. The various functions of the GUI including visualization of mass spectra, generation of 2D maps for selected species, manipulation of the heat maps, and peak identification are also presented.

Anisotropy Characterization of I-125 Seed with Attached Encapsulated Cobalt Chloride Complex Contrast Agent Markers for MRI-Based Prostate Brachytherapy  

Science Conference Proceedings (OSTI)

We have developed a novel MRI marker for prostate brachytherapy. The purpose of this study was to evaluate the changes in anisotropy when cobalt chloride complex contrast agent encapsulated contrast agent markers (C4-ECAM) were placed adjacent to an iodine-125 (I-125) titanium seed, and to verify that the C4-ECAMs were visible on magnetic resonance imaging (MRI) after radiation exposure. Two C4-ECAMs were verified to be MRI visible in a phantom before radiation exposure. The C4-ECAMs were then attached to each end of a 12.7-U (10-mCi) I-125 titanium seed in a polymer tube. Anisotropy was measured and analyzed with the seed alone and with attached C4-ECAMs by suspending thermoluminescent dosimeters in a water phantom in 2 circles surrounding the radioactive source with radius of 1 or 2 cm. A T1-weighted MRI evaluation of C4-ECAMs was then performed after exposure to the amount of radiation typically delivered during 1 month of prostate brachytherapy. Measured values of the anisotropy function F(r, {theta}) for the I-125 seed with and without the C4-ECAMs were mutually statistically indistinguishable (standard error of the mean <4.2%) and agreed well with published TG-43 values for the bare seed. As expected, the anisotropy function {phi}{sub an}(r) for the 2 datasets (with and without C4-ECAMs) derived from the measured F(r, {theta}) did not exhibit statistically measurable difference. Both datasets showed agreement with the published TG-43 {phi}{sub an}(r) for the bare seed. The C4-ECAMs were well visualized by MRI after 1 month of radiation exposure. There were no changes in anisotropy when the C4-ECAMs were placed next to an I-125 radioactive seed, and the C4-ECAMs were visualized after radiation exposure.

Interactive Visualization Package for 4D Lattice Field Theories  

E-Print Network (OSTI)

Recent interest in exploring local vacuum structure of QCD through the properties of the eigenmodes of the lattice Dirac operators rises again the challenge to visualize four-dimensional objects and structures which appear in lattice field theories. In spite of complex and powerful commercial visualization software packages on the market, there are reasons to develop Interactive Visualization Package (IVP). We believe that an apprehension of the complex structures is possible only through the interactive approach, with the user being able to manipulate data representations and slices through the lattice in real-time. Further insight should also be gained by an interactive parallel examination of different physical quantities, e.g. eigenmode density with topological charge or action densities. Finally, thanks to constantly falling hardware prices, IVP makes it possible to use almost any Linux PC as a visualization tool for research in lattice field theory.

Top Ten Interaction Challenges in Extreme-Scale Visual Analytics  

Science Conference Proceedings (OSTI)

The chapter presents ten selected user interfaces and interaction challenges in extreme-scale visual analytics. The study of visual analytics is often referred to as 'the science of analytical reasoning facilitated by interactive visual interfaces' in the literature. The discussion focuses on the issues of applying visual analytics technologies to extreme-scale scientific and non-scientific data ranging from petabyte to exabyte in sizes. The ten challenges are: in situ interactive analysis, user-driven data reduction, scalability and multi-level hierarchy, representation of evidence and uncertainty, heterogeneous data fusion, data summarization and triage for interactive query, analytics of temporally evolving features, the human bottleneck, design and engineering development, and the Renaissance of conventional wisdom. The discussion addresses concerns that arise from different areas of hardware, software, computation, algorithms, and human factors. The chapter also evaluates the likelihood of success in meeting these challenges in the near future.

Sunfall: a collaborative visual analytics system for astrophysics  

Science Conference Proceedings (OSTI)

Computational and experimental sciences produce and collect ever-larger and complex datasets, often in large-scale, multi-institution projects. The inability to gain insight into complex scientific phenomena using current software tools is a bottleneck facing virtually all endeavors of science. In this paper, we introduce Sunfall, a collaborative visual analytics system developed for the Nearby Supernova Factory, an international astrophysics experiment and the largest data volume supernova search currently in operation. Sunfall utilizes novel interactive visualization and analysis techniques to facilitate deeper scientific insight into complex, noisy, high-dimensional, high-volume, time-critical data. The system combines novel image processing algorithms, statistical analysis, and machine learning with highly interactive visual interfaces to enable collaborative, user-driven scientific exploration of supernova image and spectral data. Sunfall is currently in operation at the Nearby Supernova Factory; it is the first visual analytics system in production use at a major astrophysics project.

VisIt: a component based parallel visualization package  

SciTech Connect

We are currently developing a component based, parallel visualization and graphical analysis tool for visualizing and analyzing data on two- and three-dimensional (20, 30) meshes. The tool consists of three primary components: a graphical user interface (GUI), a viewer, and a parallel compute engine. The components are designed to be operated in a distributed fashion with the GUI and viewer typically running on a high performance visualization server and the compute engine running on a large parallel platform. The viewer and compute engine are both based on the Visualization Toolkit (VTK), an open source object oriented data manipulation and visualization library. The compute engine will make use of parallel extensions to VTK, based on MPI, developed by Los Alamos National Laboratory in collaboration with the originators of P K . The compute engine will make use of meta-data so that it only operates on the portions of the data necessary to generate the image. The meta-data can either be created as the post-processing data is generated or as a pre-processing step to using VisIt. VisIt will be integrated with the VIEWS' Tera-Scale Browser, which will provide a high performance visual data browsing capability based on multi-resolution techniques.

Interactive Remote and Distributed Visualization of Fusion Simulation Results  

Science Conference Proceedings (OSTI)

The NERSC center has unique resources that are especially tailored for interactive, high performance remote visualization. The central interactive visualization resource is Escher.nersc.gov, which is a large symmetric multiprocessor equipped with multiple gigabit interconnects to NERSC storage systems, as well as a large amount of main memory and substantial directly attached storage. Using Escher, we employ a pipelined architecture to support the demands of interactive, high-performance remote visualization. The pipelined architecture refers to an assembly-line organization of software ''workers'' that each contribute to an overall work flow. The first worker in the assembly line the server runs interactively in parallel on Escher. Parallel execution of the server provides substantial I/O and processing capabilities where it is needed close to the data. The second worker in the assembly line runs on the scientists workstation in their office, and performs 3D rendering at interactive rates. Visualization results geometry are transmitted between the two stages in the pipeline. This combination has proven effective at providing interactive 3D scientific visualization capabilities to remotely located NERSC users. Amortizing data I/O and visualization processing over parallel processors located close to the data provides capabilities that are simply not available on any desktop platform. These capabilities are an example of NERSCs commitment to providing the best possible tools and infrastructure to the computational science community.

Large Data Visualization on Distributed Memory Mulit-GPU Clusters  

Science Conference Proceedings (OSTI)

Data sets of immense size are regularly generated on large scale computing resources. Even among more traditional methods for acquisition of volume data, such as MRI and CT scanners, data which is too large to be effectively visualization on standard workstations is now commonplace. One solution to this problem is to employ a 'visualization cluster,' a small to medium scale cluster dedicated to performing visualization and analysis of massive data sets generated on larger scale supercomputers. These clusters are designed to fit a different need than traditional supercomputers, and therefore their design mandates different hardware choices, such as increased memory, and more recently, graphics processing units (GPUs). While there has been much previous work on distributed memory visualization as well as GPU visualization, there is a relative dearth of algorithms which effectively use GPUs at a large scale in a distributed memory environment. In this work, we study a common visualization technique in a GPU-accelerated, distributed memory setting, and present performance characteristics when scaling to extremely large data sets.
