Fast DRR splat rendering using common consumer graphics hardware  

Science Conference Proceedings (OSTI)

Digitally rendered radiographs (DRR) are a vital part of various medical image processing applications such as 2D/3D registration for patient pose determination in image-guided radiotherapy procedures. This paper presents a technique to accelerate DRR creation by using conventional graphics hardware for the rendering process. DRR computation itself is done by an efficient volume rendering method named wobbled splatting. For programming the graphics hardware, NVIDIAs C for Graphics (Cg) is used. The description of an algorithm used for rendering DRRs on the graphics hardware is presented, together with a benchmark comparing this technique to a CPU-based wobbled splatting program. Results show a reduction of rendering time by about 70%-90% depending on the amount of data. For instance, rendering a volume of 2x10{sup 6} voxels is feasible at an update rate of 38 Hz compared to 6 Hz on a common Intel-based PC using the graphics processing unit (GPU) of a conventional graphics adapter. In addition, wobbled splatting using graphics hardware for DRR computation provides higher resolution DRRs with comparable image quality due to special processing characteristics of the GPU. We conclude that DRR generation on common graphics hardware using the freely available Cg environment is a major step toward 2D/3D registration in clinical routine.

Resolution-independent surface rendering using programmable graphics hardware  

DOE Patents (OSTI)

Surfaces defined by a Bezier tetrahedron, and in particular quadric surfaces, are rendered on programmable graphics hardware. Pixels are rendered through triangular sides of the tetrahedra and locations on the shapes, as well as surface normals for lighting evaluations, are computed using pixel shader computations. Additionally, vertex shaders are used to aid interpolation over a small number of values as input to the pixel shaders. Through this, rendering of the surfaces is performed independently of viewing resolution, allowing for advanced level-of-detail management. By individually rendering tetrahedrally-defined surfaces which together form complex shapes, the complex shapes can be rendered in their entirety.

A Survey of Ocean Simulation and Rendering Techniques in Computer Graphics  

E-Print Network (OSTI)

This paper presents a survey of ocean simulation and rendering methods in computer graphics. To model and animate the ocean's surface, these methods mainly rely on two main approaches: on the one hand, those which approximate ocean dynamics with parametric, spectral or hybrid models and use empirical laws from oceanographic research. We will see that this type of methods essentially allows the simulation of ocean scenes in the deep water domain, without breaking waves. On the other hand, physically-based methods use Navier-Stokes Equations (NSE) to represent breaking waves and more generally ocean surface near the shore. We also describe ocean rendering methods in computer graphics, with a special interest in the simulation of phenomena such as foam and spray, and light's interaction with the ocean surface.

Parallel sphere rendering  

SciTech Connect

Sphere rendering is an important method for visualizing molecular dynamics data. This paper presents a parallel divide-and-conquer algorithm that is almost 90 times faster than current graphics workstations. To render extremely large data sets and large images, the algorithm uses the MIMD features of the supercomputers to divide up the data, render independent partial images, and then finally composite the multiple partial images using an optimal method. The algorithm and performance results are presented for the CM-5 and the T3D.

Remote interactive direct volume rendering of AMR data  

SciTech Connect

We describe a framework for direct volume rendering of adaptive mesh refinement (AMR) data that operates directly on the hierarchical grid structure, without the need to resample data onto a single, uniform rectilinear grid. The framework can be used for a range of renderers optimized for particular hardware architectures: a hardware-assisted renderer for single-processor graphics workstations, and a massively parallel software-only renderer for supercomputers. It is also possible to use the framework for distributed rendering servers. By exploiting the multiresolution structure of AMR data, the hardware-assisted renderers can render large AMR data sets at interactive rates, even if the data is stored remotely.

Using Procedural RenderMan Shaders for Global Illumination  

E-Print Network (OSTI)

Global illumination techniques like radiosity or Monte-Carlo ray-tracing are becoming standard features of rendering systems. However, there is currently no accepted interface format which supports an appropriate physically-based scene description. In this paper we present extensions to the well-known RenderMan interface, which allow for a physically based scene description and support advanced global illumination techniques. Special emphasis has been laid on the support for procedural descriptions of reflection and emission by RenderMan surface shaders. So far, they could not be used with most global illumination algorithms. The extensions have been implemented in a physically-based rendering system and are illustrated with examples. 1. Introduction In recent years physically-based rendering and global illumination have became major topics in computer graphics. While these techniques are on the edge of being used in commercial applications, it is getting more and more important to fi...

This paper presents a remote rendering application that involves the extension of the Visualization Toolkit (vtk) and the Video Conferencing Tool (vie) for use in remote rendering complete with interaction from the remote site using the vie user interface. Vtk is an open source C++ library, with Tel, Python, and Java bindings for computer graphics, image processing, and visualization [3]. Vtk provides a higher level of support, beyond the traditional low-level libraries, for creating visualization applications. Vtk includes algorithms to support the visualization of scalars, vectors, and tensors. Vic is a flexible tool built by Lawrence Berkeley National Laboratory for real-time video conferencing over the Internet [2]. Vie's user interface is built as Tcl/Tk script embedded in the applications. This allows developers to prototype changes to the interface in a simple and straightforward manner.

The F-Buffer: A Rasterization-Order FIFO Buffer for Multi-Pass Rendering  

E-Print Network (OSTI)

Multi-pass rendering is a common method of virtualizing graphics hardware to overcome limited resources. Most current multi-pass rendering techniques use the RGBA framebuffer to store intermediate results between each pass. This method of storing intermediate results makes it difficult to correctly render partially-transparent surfaces, and reduces the performance of shaders that need to preserve more than one intermediate result between passes. We propose an alternative approach to storing intermediate results that solves these problems. This approach stores intermediate colors (or other values) that are generated by a rendering pass in a FIFO buffer as the values exit the fragment pipeline. On a subsequent pass, the contents of the FIFO buffer are fed into the top of the fragment pipeline. We refer to this FIFO buffer as a fragment-stream buffer (or F-buffer), because this approach has the effect of associating intermediate results with particular rasterization fragments, rather than with an (x,y) location in the framebuffer. Implementing an F-buffer requires some changes to current mainstream graphics architectures, but these changes can be minor. We describe the design space associated with implementing an F-buffer, and compare the F-buffer to recirculating pipeline designs. We implement F-buffers in the Mesa software renderer, and demonstrate our programmable-shading system running on top of this renderer.

A Volume Rendering Extension for the OpenSG Scene Graph API  

E-Print Network (OSTI)

We will present the current state of our ongoing work on a simple to use, extensible and cross-platform volume rendering library. Primary target of our framework is interactive scientific visualization, but volumetric effects are also desirable in other fields of computer graphics, e.g. virtual reality applications. The framework we present is based on texture-based direct volume rendering. We apply the concept of volume shaders and demonstrate their usefulness in terms of flexibility, extensibility and adaption to new or different graphics hardware. Our framework is based on the OpenSG scene graph API, that is designed especially with multi-threading and cluster-rendering in mind, thus, it is very easy to integrate volumetric visualizations into powerful virtual reality systems.

Introduction to Graphical Modelling  

E-Print Network (OSTI)

The aim of this chapter is twofold. In the first part we will provide a brief overview of the mathematical and statistical foundations of graphical models, along with their fundamental properties, estimation and basic inference procedures. In particular we will develop Markov networks (also known as Markov random fields) and Bayesian networks, which comprise most past and current literature on graphical models. In the second part we will review some applications of graphical models in systems biology.

Use of Hybrid Rendering Styles for Presentation  

E-Print Network (OSTI)

This paper presents hybrid rendering that combines the use of photorealistic and non-photorealistic rendering styles in the same image. This allows to extend the set of expression dimensions available in a visualization environment. To provide general applicability, this use of hybrid rendering styles is controlled by an XML-based scene description. We discuss the according schema definition and present an architecture for implementing the presented methods as well as two exemplary applications.

Graphics Turing Test  

E-Print Network (OSTI)

We define a Graphics Turing Test to measure graphics performance in a similar manner to the definition of the traditional Turing Test. To pass the test one needs to reach a computational scale, the Graphics Turing Scale, for which Computer Generated Imagery becomes comparatively indistinguishable from real images while also being interactive. We derive an estimate for this computational scale which, although large, is within reach of todays supercomputers. We consider advantages and disadvantages of various computer systems designed to pass the Graphics Turing Test. Finally we discuss commercial applications from the creation of such a system, in particular Interactive Cinema. Defining graphics computing scales can be difficult. Traditional methods such as counting triangles drawn per second can be misleading especially if a large per-centage of the computing power is going into shading code or a physics simulation which can be involved in making the graphics image realistic. More than fifty years ago Alan Turing faced a similar challenge in evaluating the

A shader based approach to painterly rendering  

E-Print Network (OSTI)

The purpose of this thesis is to develop a texture-based painterly shader that would render computer generated objects or scenes with strokes that are visually similar to paint media like watercolor, oil paint or dry media such as crayons, chalk, et cetera. This method would need an input scene in the form of three dimensional polygonal or NURBS meshes. While the structure of the meshes and the lighting in the scene would both play a crucial role in the ?nal appearance of the scene, the painterly look will be imparted through a shader. This method, therefore, is essentially a rendering technique. Several modi?able parameters in the shader gives the user artistic freedom while overall introducing some amount of automation in the painterly rendering process.

Research Statement: Multiresolution in Graphics and Simulation  

E-Print Network (OSTI)

Introduction and Summary The primary goal of my research is to develop simple computational models for simulating the behavior of physical systems. I draw on ideas from graphics, applied mathematics, di#erential geometry, and engineering. My research shows that simple approaches need not sacrifice accuracy or performance. Simple approaches lead to more insight, wider adoption by the scientific computing community, and the opportunity to pursue more ambitious applications to mechanical engineering, medicine, biology, and computer graphics. With this philosophy in mind I am focusing on two key aspects of simulation. First, to improve scalability of simulators with respect to large datasets and high geometric complexity, I am developing a framework for adaptive multiresolution simulation. Second, I am developing discrete models: geometric descriptions of physical phenomena distilled into their most fundamental form.

Evaluation of Subdivision Surfaces on Programmable Graphics Hardware  

E-Print Network (OSTI)

High-order smooth surface primitives, such as subdivision patches for example, are attractive for the modeling of free-form surfaces. In contrast to meshes they require only a few control points to specify large sections of a surface. Unfortunately, much of this bandwidth advantage is lost when such surfaces have to be tessellated on the CPU prior to transmission over the graphics bus and rendering on the graphics card. For surfaces built through linear combination of basis functions it is possible to precompute tessellations and use these to evaluate the surface at runtime in a simple computation performed entirely on a programmable graphics processor (GPU). The improved bandwidth requirements---only control points need transmission during animation, for example---coupled with the high performance of GPUs, allows us to achieve tessellation rates up to 24 million vertices per second on a 500 MHz GeForce FX.

Graphical Representation of Supersymmetry  

E-Print Network (OSTI)

A graphical representation of supersymmetry is presented. It clearly expresses the chiral flow appearing in SUSY quantities, by representing spinors by {\\it directed lines} (arrows). The chiral suffixes are expressed by the directions (up, down, left, right) of the arrows. The SL(2,C) invariants are represented by {\\it wedges}. Both the Weyl spinor and the Majorana spinor are treated. We are free from the complicated symbols of spinor suffixes. The method is applied to the 5D supersymmetry. Many applications are expected. The result is suitable for coding a computer program and is highly expected to be applicable to various SUSY theories (including Supergravity) in various dimensions.

Development of computer graphics  

SciTech Connect

The purpose of this project was to screen and evaluate three graphics packages as to their suitability for displaying concentration contour graphs. The information to be displayed is from computer code simulations describing air-born contaminant transport. The three evaluation programs were MONGO (John Tonry, MIT, Cambridge, MA, 02139), Mathematica (Wolfram Research Inc.), and NCSA Image (National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign). After a preliminary investigation of each package, NCSA Image appeared to be significantly superior for generating the desired concentration contour graphs. Hence subsequent work and this report describes the implementation and testing of NCSA Image on both an Apple MacII and Sun 4 computers. NCSA Image includes several utilities (Layout, DataScope, HDF, and PalEdit) which were used in this study and installed on Dr. Ted Yamada`s Mac II computer. Dr. Yamada provided two sets of air pollution plume data which were displayed using NCSA Image. Both sets were animated into a sequential expanding plume series.

Local and Global Illumination in the Volume Rendering Integral  

SciTech Connect

This article is intended as an update of the major survey by Max [1] on optical models for direct volume rendering. It provides a brief overview of the subject scope covered by [1], and brings recent developments, such as new shadow algorithms and refraction rendering, into the perspective. In particular, we examine three fundamentals aspects of direct volume rendering, namely the volume rendering integral, local illumination models and global illumination models, in a wavelength-independent manner. We review the developments on spectral volume rendering, in which visible light are considered as a form of electromagnetic radiation, optical models are implemented in conjunction with representations of spectral power distribution. This survey can provide a basis for, and encourage, new efforts for developing and using complex illumination models to achieve better realism and perception through optical correctness.

Extending Document Summarization to Information Graphics  

E-Print Network (OSTI)

Information graphics (non-pictorial graphics such as bar charts or line graphs) are an important component of multimedia documents. Often such graphics convey information that is not contained elsewhere in the document. Thus document summarization must be extended to include summarization of information graphics. This paper addresses our work on graphic summarization. It argues that the message that the graphic designer intended to convey must play a major role in determining the content of the summary, and it outlines our approach to identifying this intended message and using it to construct the summary. 1

Blasting, graphical interfaces and Unix  

SciTech Connect

A discrete element computer program, DMC (Distinct Motion Code) was developed to simulate blast-induced rock motion. To simplify the complex task of entering material and explosive design parameters as well as bench configuration, a full-featured graphical interface has been developed. DMC is currently executed on both Sun SPARCstation 2 and Sun SPARCstation 10 platforms and routinely used to model bench and crater blasting problems. This paper will document the design and development of the full-featured interface to DMC. The development of the interface will be tracked through the various stages, highlighting the adjustments made to allow the necessary parameters to be entered in terms and units that field blasters understand. The paper also discusses a novel way of entering non-integer numbers and the techniques necessary to display blasting parameters in an understandable visual manner. A video presentation will demonstrate the graphics interface and explains its use.

PICASSO: A GENERAL INTERACTIVE GRAPHICS MODELING PROGRAM.  

DOE Green Energy (OSTI)

This report is intended to serve as a user's manual for PICASSO. The detailed description of the concepts involved and the methods used in implementing those concepts will be treated in a subsequent paper and are incorporated in the Ph.D. thesis of one of the authors. The program evolved from earlier work on a graphics program for printed circuit board design which had a fixed library of elements. The need for a dynamic graphics program (i.e., one which allows the creation of new elements as required) soon became obvious, and the generality of such a program for mathematical modeling was a major factor in the development of PICASSO. It was thought that the present stage of development of this modeling program had reached a point that a report such as this would be useful in creating a broader interest in the field. However, work continues to further generalize the program into such areas as computer animation, 3-D display and modeling, and a more general interface to available ''analysis'' routines, such as the available compilers and interpreters. It should be emphasized that the program is continually changing as new ideas and applications arise. For example, in order to create a modeling system which is complete in some sense, PICASSO was designed explicitly to interface with the CDC analysis program MIMIC. The next step, already under investigation, is to allow for user-defined output templates to specify,the form of the output of a model. This feature, along with the capability for multiple definitions of an element, will allow for several types of analysis to be done on a single model. Another innovation being studied is the provision for ''robot'' commands, with which the user may define a sequence of. commands to be carried out on demand, in much the same way as mechanical ''robots'' are programmed. For this reason there will usually be several versions of PICASSO available, one of which is relatively ''bug-free''. The authors wish to gratefully acknowledge support from the Math and. Computing Division and the Electrical Engineering Department of the Lawrence Berkeley Laboratory, and the Department of Electrical Engineering and Computer Science of the University of California, Berkeley. Specifically, we wish to thank Ivan Wood and Horace Warnock of EE Drafting for support and many suggestions; Michiyuki Nakamura, Richard LaPierre, John Mendes, Don Evans and Frank Neu of EE Research and Development for many suggestions and interesting applications; Professor Baskin, EECS Department, UCB, James Baker and Carl Quong, Math and Computing, LBL for support and encouragement; and Norma Hart for preparing the manuscript.

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...

Interpreting the visual and cinematic style of Japanese anime using three-dimensional computer graphics  

E-Print Network (OSTI)

Due to the international popularity of Japanese anime and its recognition as a cinematic art form, creative professionals in the animation industry are impressed with not only the complexity and artistic fluidity of the animation style but also the variety of narrative themes. As an acceptable alternative to live action films, Japanese directors and animators have more liberty with narrative themes and explicit imagery in anime than their western counterparts, and anime is attracting a variety of audiences ranging from young children to adults. As a stylistic form of animation with a distinct line art style, anime is traditionally produced by hand. With the development of non-photorealistic rendering techniques such as toon shading, three-dimensional computer graphics are used in anime production, though with limited application. This thesis attempts to interpret the visual and cinematic style of anime entirely within a three-dimensional digital environment through character design, modeling, character animation, cinematography, and non-photorealistic rendering.

Real-Time Out-of-Core Rendering  

E-Print Network (OSTI)

Hierarchical levels of details (HLODs) have proven to be an efficient way to visualize complex environments and models even in an out-of-core system. Large objects are partitioned into a spatial hierarchy and for each node a level of detail is generated for efficient view-dependent rendering. To ensure correct matching between adjacent nodes in the hierarchy care has to be taken to prevent cracks along the cuts. This either leads to severe simplification constraints at the cuts and thus to a significantly higher number of triangles or the need for a costly runtime stitching of these nodes. In this paper we present an out-of-core visualization algorithm that overcomes this problem by filling the cracks generated by the simplification algorithm with appropriately shaded Fat Borders. Furthermore, several minor yet important improvements of previous approaches are made. This way we come up with a simple nevertheless efficient viewdependent rendering technique which allows for the natural incorporation of state-of-theart culling, simplification, compression and prefetching techniques leading to real-time rendering performance of the overall system. Several examples demonstrate the efficiency of our approach.

Customising Graphics Applications: Techniques and Programming Interface  

E-Print Network (OSTI)

This paper identifies opportunities for customising architectures for graphics applications, such as infrared simulation and geometric visualisation. We have studied methods for exploiting custom data formats and datapath widths, and for optimising graphics operations such as texture mapping and hidden-surface removal. Techniques for balancing the graphics pipeline and for runtime reconfiguration have been implemented. The customised architectures are captured in Handel-C, a Clike language supporting parallelism and flexible data size, and compiled for Xilinx 4000 and Virtex FPGAs. We have also developed an application programming interface based on the OpenGL standard for automatic speedup of graphics applications, including the Quake 2 action game. 1 Introduction Despite tremendous progress in the last thirty years, real-time generation of realistic images still offers many challenges. The demand for realism requires improvement in algorithms, frame rate and resolution, while the v...

Graphical calculus for Gaussian pure states  

E-Print Network (OSTI)

We provide a unified graphical calculus for all Gaussian pure states, including graph transformation rules for all local and semi-local Gaussian unitary operations, as well as local quadrature measurements. We then use this graphical calculus to analyze continuous-variable (CV) cluster states, the essential resource for one-way quantum computing with CV systems. Current graphical approaches to CV cluster states are only valid in the unphysical limit of infinite squeezing, and the associated graph transformation rules only apply when the initial and final states are of this form. Our formalism applies to all Gaussian pure states and subsumes these rules in a natural way. In addition, the term "CV graph state" currently has several inequivalent definitions in use. Using this formalism we provide a single unifying definition that encompasses all of them. We provide many examples of how the formalism may be used in the context of CV cluster states: defining the "closest" CV cluster state to a given Gaussian pure state and quantifying the error in the approximation due to finite squeezing; analyzing the optimality of certain methods of generating CV cluster states; drawing connections between this new graphical formalism and bosonic Hamiltonians with Gaussian ground states, including those useful for CV one-way quantum computing; and deriving a graphical measure of bipartite entanglement for certain classes of CV cluster states. We mention other possible applications of this formalism and conclude with a brief note on fault tolerance in CV one-way quantum computing.

Applying Object-Oriented Design to Structured Graphics  

E-Print Network (OSTI)

Structured graphics is useful for building applications that use a direct manipulation metaphor. Objectoriented languages offer inheritance, encapsulation, and runtime binding of operations to objects. Unfortunately, standard structured graphics packages do not use an object-oriented model, and object-oriented systems do not provide general-purpose structured graphics, relying instead on low-level graphics primitives. An object-oriented approach to structured graphics can give application programmers the benefits of both paradigms. We have implemented a two-dimensional structured graphics library in C++ that presents an object-oriented model to the programmer. The graphic class defines a general graphical object from which all others are derived. The picture subclass supports hierarchical composition of graphics. Programmers can define new graphical objects either statically by subclassing or dynamically by composing instances of existing classes. We have used both this library and an...

On-the-Fly Decompression and Rendering of Multiresolution Terrain  

SciTech Connect

We present a streaming geometry compression codec for multiresolution, uniformly-gridded, triangular terrain patches that supports very fast decompression. Our method is based on linear prediction and residual coding for lossless compression of the full-resolution data. As simplified patches on coarser levels in the hierarchy already incur some data loss, we optionally allow further quantization for more lossy compression. The quantization levels are adaptive on a per-patch basis, while still permitting seamless, adaptive tessellations of the terrain. Our geometry compression on such a hierarchy achieves compression ratios of 3:1 to 12:1. Our scheme is not only suitable for fast decompression on the CPU, but also for parallel decoding on the GPU with peak throughput over 2 billion triangles per second. Each terrain patch is independently decompressed on the fly from a variable-rate bitstream by a GPU geometry program with no branches or conditionals. Thus we can store the geometry compressed on the GPU, reducing storage and bandwidth requirements throughout the system. In our rendering approach, only compressed bitstreams and the decoded height values in the view-dependent 'cut' are explicitly stored on the GPU. Normal vectors are computed in a streaming fashion, and remaining geometry and texture coordinates, as well as mesh connectivity, are shared and re-used for all patches. We demonstrate and evaluate our algorithms on a small prototype system in which all compressed geometry fits in the GPU memory and decompression occurs on the fly every rendering frame without any cache maintenance.

Approaching the exa-scale: a real-world evaluation of rendering extremely large data sets  

Science Conference Proceedings (OSTI)

Extremely large scale analysis is becoming increasingly important as supercomputers and their simulations move from petascale to exascale. The lack of dedicated hardware acceleration for rendering on today's supercomputing platforms motivates our detailed evaluation of the possibility of interactive rendering on the supercomputer. In order to facilitate our understanding of rendering on the supercomputing platform, we focus on scalability of rendering algorithms and architecture envisioned for exascale datasets. To understand tradeoffs for dealing with extremely large datasets, we compare three different rendering algorithms for large polygonal data: software based ray tracing, software based rasterization and hardware accelerated rasterization. We present a case study of strong and weak scaling of rendering extremely large data on both GPU and CPU based parallel supercomputers using Para View, a parallel visualization tool. Wc use three different data sets: two synthetic and one from a scientific application. At an extreme scale, algorithmic rendering choices make a difference and should be considered while approaching exascale computing, visualization, and analysis. We find software based ray-tracing offers a viable approach for scalable rendering of the projected future massive data sizes.

An adaptable computing environment is implemented with software entities termed "s-machines", which self-assemble into hierarchical data structures capable of rendering and interacting with the computing environment. A hierarchical data structure includes a first hierarchical s-machine bound to a second hierarchical s-machine. The first hierarchical s-machine is associated with a first layer of a rendering region on a display screen and the second hierarchical s-machine is associated with a second layer of the rendering region overlaying at least a portion of the first layer. A screen element s-machine is linked to the first hierarchical s-machine. The screen element s-machine manages data associated with a screen element rendered to the display screen within the rendering region at the first layer.

Scientific statistics and graphics on the Macintosh  

SciTech Connect

In many organizations scientists have ready access to more than one computer, often both a workstation (e.g., SUN, HIP, SGI) as well as a Macintosh or other PC. The scientist commonly uses the work station for {open_quotes}number-crunching{close_quotes} and data analysis whereas the Macintosh is relegated to either word processing or serves as a {open_quotes}dumb terminal{close_quotes} to a larger mainframe computer. In an informal poll of the author`s colleagues, very few of them used their Macintoshes for either statistical analysis or for graphical data display. The author believes that this state of affairs is particularly unfortunate because over the last few years both the computational capability, and even more so, the software availability for the Macintosh have become quite formidable. In some instances, very powerful tools are now available on the Macintosh that may not exist (or be far too costly) on the so-called {open_quotes}high end{close_quotes} workstations. Many scientists are simply unaware of the wealth of extremely useful, {open_quotes}off-the-shelf{close_quote} software that already exists on the Macintosh for scientific graphical and statistical analysis. This paper is a very personal view illustrating several such software packages that have proved valuable in the author`s own work in the analysis and display of climatic datasets. It is not meant to be either an all-inclusive enumeration, nor is it to be taken as an endorsement of these products as the {open_quotes}best{close_quotes} of their class. Rather, it has been found, through extensive use that these few packages were generally capable of satisfying his particular needs for both statistical analysis and graphical data display. In the limited space available, the focus will be on some of the more novel features found to be of value.

We discuss an implementation of molecular dynamics (MD) simulations on a graphic processing unit (GPU) in the NVIDIA CUDA language. We tested our code on a modern GPU, the NVIDIA GeForce 8800 GTX. Results for two MD algorithms suitable for short-ranged and long-ranged interactions, and a congruential shift random number generator are presented. The performance of the GPU's is compared to their main processor counterpart. We achieve speedups of up to 80, 40 and 150 fold, respectively. With newest generation of GPU's one can run standard MD simulations at 10^7 flops/$.

Graphical Representation of Supersymmetry and Computer Calculation  

E-Print Network (OSTI)

A graphical representation of supersymmetry is presented. It clearly expresses the chiral flow appearing in SUSY quantities, by representing spinors by {\\it directed lines} (arrows). The chiral suffixes are expressed by the directions (up, down, left, right) of the arrows. The SL(2,C) invariants are represented by {\\it wedges}. We are free from the messy symbols of spinor suffixes. The method is applied to the 5D supersymmetry. Many applications are expected. The result is suitable for coding a computer program and is highly expected to be applicable to various SUSY theories (including Supergravity) in various dimensions.

Data Reduction and Analysis Graphical Organizer  

E-Print Network (OSTI)

Spectroscopic surveys are undergoing a rapid expansion in their data collecting capabilities, reaching the level of hundreds of spectra per pointing. An efficient use of such huge amounts of information requires a high degree of interconnection between the various tools involved in preparing the observations, reducing the data, and carrying out the data analysis. DRAGO (Data Reduction and Analysis Graphical Organizer) attempts to easy the process, by integrating in a global framework the main data handling components: from reduction pipelines, to data organization, plotting, and browsing tools, to storing the data reduction results in a database for further analysis. DRAGO allows the use of the astronomer own's preferred tools, by "plugging them in" in an environment which handles transparently the communications between them.

Unified Graphical Summary of Neutrino Mixing Parameters  

E-Print Network (OSTI)

The neutrino mixing parameters are presented in a number of different ways by the various experiments, e.g. SuperKamiokande, K2K, SNO, KamLAND and Chooz and also by the Particle Data Group. In this paper, we argue that presenting the data in terms of $\\sin^2 \\theta$, where $\\theta$ is the mixing angle appropriate for a given experiment has a direct physical interpretation. For current atmospheric, solar and reactor neutrino experiments, the $\\sin^2 \\theta$'s are effectively the probability of finding a given flavor in a particular neutrino mass eigenstate. The given flavor and particular mass eigenstate varies from experiment to experiment, however, the use of $\\sin^2 \\theta$ provides a unified picture of all the data. Using this unified picture we present a graphical way to represent these neutrino mixing parameters which includes the uncertainties. All of this is performed in the context of the present experimental status of three neutrino oscillations.

Partial Wave Analysis using Graphics Cards  

E-Print Network (OSTI)

Partial wave analysis is a key technique in hadron spectroscopy. The use of unbinned likelihood fits on large statistics data samples and ever more complex physics models makes this analysis technique computationally very expensive. Parallel computing techniques, in particular the use of graphics processing units, are a powerful means to speed up analyses; in the contexts of the BES III, Compass and GlueX experiments, parallel analysis frameworks have been created. They provide both fits that are faster by more than two orders of magnitude than legacy code and environments to quickly program and run an analysis. This in turn allows the physicists to focus on the many difficult open problems pertaining to partial wave analysis.

Graphical Quantum Error-Correcting Codes  

E-Print Network (OSTI)

We introduce a purely graph-theoretical object, namely the coding clique, to construct quantum errorcorrecting codes. Almost all quantum codes constructed so far are stabilizer (additive) codes and the construction of nonadditive codes, which are potentially more efficient, is not as well understood as that of stabilizer codes. Our graphical approach provides a unified and classical way to construct both stabilizer and nonadditive codes. In particular we have explicitly constructed the optimal ((10,24,3)) code and a family of 1-error detecting nonadditive codes with the highest encoding rate so far. In the case of stabilizer codes a thorough search becomes tangible and we have classified all the extremal stabilizer codes up to 8 qubits.

A nNon-photorealistic Model for Procedural Painterly Rendered Trees in the Style of Corot  

E-Print Network (OSTI)

This thesis describes the development of a system for the procedural generation and painterly rendering of trees. Specifically, the rendered trees are modeled after those found in the oil landscape paintings of 19th century French painter Camille Corot. The rendering system, which is a combination of MEL-scripted Maya tools and Renderman shaders, facilitates the creation of still images that look convincingly painterly, as well as 3D animations with temporal coherence. Brush stroke properties are animated based on distance from the camera, so that traditional painting techniques for representing depth are incorporated into the computer-generated animations. During the development process, the system was generalized to apply to other structures, such as grass and rocks, and allows for the creation and rendering of entire landscapes. Several example animations were created with the system to demonstrate the ideas developed during the process and the quality of the results.

Exhaust gas recirculation in a homogeneous charge compression ignition engine  

DOE Patents (OSTI)

A homogeneous charge compression ignition engine operates by injecting liquid fuel directly in a combustion chamber, and mixing the fuel with recirculated exhaust and fresh air through an auto ignition condition of the fuel. The engine includes at least one turbocharger for extracting energy from the engine exhaust and using that energy to boost intake pressure of recirculated exhaust gas and fresh air. Elevated proportions of exhaust gas recirculated to the engine are attained by throttling the fresh air inlet supply. These elevated exhaust gas recirculation rates allow the HCCI engine to be operated at higher speeds and loads rendering the HCCI engine a more viable alternative to a conventional diesel engine.

Quantum Graphical Models and Belief Propagation  

E-Print Network (OSTI)

Belief Propagation algorithms acting on Graphical Models of classical probability distributions, such as Markov Networks, Factor Graphs and Bayesian Networks, are amongst the most powerful known methods for deriving probabilistic inferences amongst large numbers of random variables. This paper presents a generalization of these concepts and methods to the quantum case, based on the idea that quantum theory can be thought of as a noncommutative, operator-valued, generalization of classical probability theory. Some novel characterizations of quantum conditional independence are derived, and definitions of Quantum n-Bifactor Networks, Markov Networks, Factor Graphs and Bayesian Networks are proposed. The structure of Quantum Markov Networks is investigated and some partial characterization results are obtained, along the lines of the Hammersely-Clifford theorem. A Quantum Belief Propagation algorithm is presented and is shown to converge on 1-Bifactor Networks and Markov Networks when the underlying graph is a tree. The use of Quantum Belief Propagation as a heuristic algorithm in cases where it is not known to converge is discussed. Applications to decoding quantum error correcting codes and to the simulation of many-body quantum systems are described.

A Practical Framework for Sharing and Rendering Real-World Bidirectional A Practical Framework for Sharing and Rendering Real-World Bidirectional Scattering Distribution Functions Title A Practical Framework for Sharing and Rendering Real-World Bidirectional Scattering Distribution Functions Publication Type Report LBNL Report Number LBNL-5954E Year of Publication 2012 Authors Ward, Gregory J., Murat Kurt, and Nicolas Bonneel Date Published 10/2012 Keywords building technology and urban systems department, windows and envelope materials group Abstract The utilization of real-world materials has been hindered by a lack of standards for sharing and interpreting measured data. This paper presents an XML representation and an Open Source C library to support bidirectional scattering distribution functions (BSDFs) in data-driven lighting simulation and rendering applications.The library provides for the efficient representation, query, and Monte Carlo sampling of arbitrary BSDFs in amodel-free framework. Currently, we support two BSDF data representations: one using a fixed subdivision of thehemisphere, and one with adaptive density. The fixed type has advantages for certain matrix operations, while theadaptive type can more accurately represent highly peaked data. We discuss advanced methods for data-driven BSDF rendering for both types, including the proxy of detailed geometry to enhance appearance and accuracy. We also present an advanced interpolation method to reduce measured data into these standard representations. We end with our plan for future extensions and sharing of BSDF data.

Engine Removal Projection Tool  

DOE Green Energy (OSTI)

The US Navy has over 3500 gas turbine engines used throughout the surface fleet for propulsion and the generation of electrical power. Past data is used to forecast the number of engine removals for the next ten years and determine engine down times between removals. Currently this is done via a FORTRAN program created in the early 1970s. This paper presents results of R&D associated with creating a new algorithm and software program. We tested over 60 techniques on data spanning 20 years from over 3100 engines and 120 ships. Investigated techniques for the forecast basis including moving averages, empirical negative binomial, generalized linear models, Cox regression, and Kaplan Meier survival curves, most of which are documented in engineering, medical and scientific research literature. We applied those techniques to the data, and chose the best algorithm based on its performance on real-world data. The software uses the best algorithm in combination with user-friendly interfaces and intuitively understandable displays. The user can select a specific engine type, forecast time period, and op-tempo. Graphical displays and numerical tables present forecasts and uncertainty intervals. The technology developed for the project is applicable to other logistic forecasting challenges.

High Performance Flow Simulations on Graphics Processing Units High Performance Flow Simulations on Graphics Processing Units Speaker(s): Wangda Zuo Date: June 17, 2010 - 12:00pm Location: 90-3122 Seminar Host/Point of Contact: Michael Wetter Building design and operation often requires real-time or faster-than-real-time simulations for detailed information on air distributions. However, none of the current flow simulation techniques can satisfy this requirement. To solve this problem, a Fast Fluid Dynamics (FFD) model has been developed. The FFD can solve Navier-Stokes equations at a speed of 50 times faster than Computational Fluid Dynamics (CFD). In addition, the computing speed of the FFD program has been further enhanced up to 30 times by executing in parallel on a Graphics Processing Unit (GPU) instead of a Central Processing Unit (CPU).

A Graphical representation of the grand canonical partition function  

E-Print Network (OSTI)

In this paper we consider a stochastic partial differential equation defined on a Lattice $L_\\delta$ with coefficients of non-linearity with degree $p$. An analytic solution in the sense of formal power series is given. The obtained series can be re-expressed in terms of rooted trees with two types of leaves. Under the use of the so-called Cole-Hopf transformation and for the particular case $p=2$, one thus get the generalized Burger equation. A graphical representation of the solution and its logarithm is done in this paper. A discussion of the summability of the previous formal solutions is done in this paper using Borel sum. A graphical calculus of the correlation function is given. The special case when the noise is of L\\'evy type gives a simplified representations of the solution of the generalized Burger equation. From the previous results we recall a graphical representation of the grand canonical partition function.

New method for abbreviating the fault tree graphical representation  

SciTech Connect

Fault tree analysis is being widely used for reliability and safety analysis of systems encountered in the nuclear industry and elsewhere. A disadvantage of the fault tree method is the voluminous fault tree graphical representation that conventionally results from analysis of a complex system. Previous methods for shortening the fault tree graphical representation include (1) transfers within the fault tree, and (2) the use of the SAMPLE (K out of N logic) gate, the MATRIX gate, and the SUMMATION gate. The purpose of this presentation is to introduce TABULATION gates as a method to abbreviate the fault tree graphical representation. These new gates reduce the cost of analysis and generally increase the system behavior visibility that is inherent in the fault tree technique. (auth)

Graphical functions and single-valued multiple polylogarithms  

E-Print Network (OSTI)

Graphical functions are single-valued complex functions which arise from Feynman amplitudes. We study their properties and use their connection to multiple polylogarithms to calculate Feynman periods. For the zig-zag and two more families of phi^4 periods we give exact results modulo products. These periods are proved to be expressible as integer linear combinations of single-valued multiple polylogarithms evaluated at one. For the larger family of 'constructible' graphs we give an algorithm that allows one to calculate their periods by computer algebra. The theory of graphical functions is used to prove the zig-zag conjecture.

Producing EGS4 shower displays with the Unified Graphics System  

Science Conference Proceedings (OSTI)

The EGS4 Code System has been coupled with the SLAC Unified Graphics System in such a manner as to provide a means for displaying showers on UGS77-supported devices. This is most easily accomplished by attaching an auxiliary subprogram package (SHOWGRAF) to existing EGS4 User Codes and making use of a graphics display or a post-processor code called EGS4PL. SHOWGRAF may be used to create shower displays directly on interactive IBM 5080 color display devices, supporting three-dimensional rotations, translations, and zoom features, and providing illustration of particle types and energies by color and/or intensity. Alternatively, SHOWGRAF may be used to record a two-dimensional projection of the shower in a device-independent graphics file. The EGS4PL post-processor may then be used to convert this file into device-dependent graphics code for any UGS77-supported device. Options exist within EGS4PL that allow for two-dimensional translations and zoom, for creating line structure to indicate particle types and energies, and for optional display of particles by type. All of this is facilitated by means of the command processor EGS4PL EXEC together with new options (5080 and PDEV) with the standard EGS4IN EXEC routine for running EGS4 interactively under VM/SP. 6 refs.

Development of an embedded 3D graphics processor  

E-Print Network (OSTI)

Limitations in processing ability cause major graphical enhancements, such as support for real-time 3D graphics, to be next to impossible within embedded devices. Due to the size, power, and heat dissipation requirements, modern graphics hardware is usually restricted to systems on the scale of personal computers or larger. For this thesis, we have defined a 3D graphics co-processor that is targeted to work on a more embedded scale. The system is specified by limiting it to fixed-point light processing and rasterization. A set of object primitives and instructions are defined to adequately describe almost any scene. These primitives are used to design the algorithms and architecture behind a set of modular functional units. The units are used to realize the processor requirements and features, which include light processing, z-buffering, texturing, and transparency. In order to ensure that the system architecture is versatile in its design, the functional units are analyzed for performance, reconfigurability, and possible trade-offs. A set of both synchronous and asynchronous architectures are proposed using the functional unit blocks. Through cycle accurate comparative simulation, we analyzed the effectiveness of each architecture and found that a hybrid architecture provides the best hardware to speed trade-off between the architectures considered. An appropriate system interface and parallel configuration are also discussed. The end result of the thesis provides a road map for anyone designing a general purpose or application optimized embedded 3D co-processor.

Shockwave Engine: Wave Disk Engine  

Science Conference Proceedings (OSTI)

Broad Funding Opportunity Announcement Project: MSU is developing a new engine for use in hybrid automobiles that could significantly reduce fuel waste and improve engine efficiency. In a traditional internal combustion engine, air and fuel are ignited, creating high-temperature and high-pressure gases which expand rapidly. This expansion of gases forces the engine’s pistons to pump and powers the car. MSU’s engine has no pistons. It uses the combustion of air and fuel to build up pressure within the engine, generating a shockwave that blasts hot gas exhaust into the blades of the engine’s rotors causing them to turn, which generates electricity. MSU’s redesigned engine would be the size of a cooking pot and contain fewer moving parts—reducing the weight of the engine by 30%. It would also enable a vehicle that could use 60% of its fuel for propulsion.

A data distributed, parallel algorithm for ray-traced volume rendering  

Science Conference Proceedings (OSTI)

This paper presents a divide-and-conquer ray-traced volume rendering algorithm and its implementation on networked workstations and a massively parallel computer, the Connection Machine CM-5. This algorithm distributes the data and the computational load to individual processing units to achieve fast, high-quality rendering of high-resolution data, even when only a modest amount of memory is available on each machine. The volume data, once distributed, is left intact. The processing nodes perform local ray-tracing of their subvolume concurrently. No communication between processing units is needed during this locally ray-tracing process. A subimage is generated by each processing unit and the final image is obtained by compositing subimages in the proper order, which can be determined a priori. Implementations and tests on a group of networked workstations and on the Thinking Machines CM-5 demonstrate the practicality of our algorithm and expose different performance tuning issues for each platform. We use data sets from medical imaging and computational fluid dynamics simulations in the study of this algorithm.

An Alternate Graphical Representation of Periodic table of Chemical Elements  

E-Print Network (OSTI)

Periodic table of chemical elements symbolizes an elegant graphical representation of symmetry at atomic level and provides an overview on arrangement of electrons. It started merely as tabular representation of chemical elements, later got strengthened with quantum mechanical description of atomic structure and recent studies have revealed that periodic table can be formulated using SO(4,2)* SU(2) group. IUPAC, the governing body in Chemistry, doesn't approve any periodic table as a standard periodic table. The only specific recommendation provided by IUPAC is that the periodic table should follow the 1 to 18 group numbering. In this technical paper, we describe a new graphical representation of periodic table, referred as 'Circular form of Periodic table'. The advantages of circular form of periodic table over other representations are discussed along with a brief discussion on history of periodic tables.

K.L.: Parallel evolutionary algorithms on graphics processing unit  

E-Print Network (OSTI)

Abstract- Evolutionary Algorithms (EAs) are effective and robust methods for solving many practical problems such as feature selection, electrical circuits synthesis, and data mining. However, they may execute for a long time for some difficult problems, because several fitness evaluations must be performed. A promising approach to overcome this limitation is to parallelize these algorithms. In this paper, we propose to implement a parallel EA on consumer-level graphics cards. We perform experiments to compare our parallel EA with an ordinary EA and demonstrate that the former is much more effective than the latter. Since consumer-level graphics cards are available in ubiquitous personal computers and these computers are easy to use and manage, more people will be able to use our parallel algorithm to solve their problems encountered in real-world applications. 1

Computing trends using graphic processor in high energy physics  

E-Print Network (OSTI)

One of the main challenges in Heavy Energy Physics is to make fast analysis of high amount of experimental and simulated data. At LHC-CERN one p-p event is approximate 1 Mb in size. The time taken to analyze the data and obtain fast results depends on high computational power. The main advantage of using GPU(Graphic Processor Unit) programming over traditional CPU one is that graphical cards bring a lot of computing power at a very low price. Today a huge number of application(scientific, financial etc) began to be ported or developed for GPU, including Monte Carlo tools or data analysis tools for High Energy Physics. In this paper, we'll present current status and trends in HEP using GPU.

SRF Test Areas Cryogenic System Controls Graphical User Interface  

SciTech Connect

Fermi National Accelerator Laboratory has constructed a superconducting 1.3 GHz cavity test facility at Meson Detector Building (MDB) and a superconducting 1.3 GHz cryomodule test facility located at the New Muon Lab Building (NML). The control of these 2K cryogenic systems is accomplished by using a Synoptic graphical user interface (GUI) to interact with the underlying Fermilab Accelerator Control System. The design, testing and operational experience of employing the Synoptic client-server system for graphical representation will be discussed. Details on the Synoptic deployment to the MDB and NML cryogenic sub-systems will also be discussed. The implementation of the Synoptic as the GUI for both NML and MDB has been a success. Both facilities are currently fulfilling their individual roles in SCRF testing as a result of successful availability of the cryogenic systems. The tools available for creating Synoptic pages will continue to be developed to serve the evolving needs of users.

Graphical rule of transforming continuous-variable graph states by local homodyne detection  

E-Print Network (OSTI)

Graphical rule, describing that any single-mode homodyne detection turns a given continuous-variable (CV) graph state into a new one, is presented. Employing two simple graphical rules: local complement operation and vertex deletion (single quadrature-amplitude $\\hat{x}$ measurement), the graphical rule for any single-mode quadrature component measurement can be obtained. The shape of CV weighted graph state may be designed and constructed easily from a given larger graph state by applying this graphical rule.

Web queries with style: Rendering xcerpt programs with css-ng  

E-Print Network (OSTI)

Abstract. Styling and formatting of XML documents for various target media is often specified with the Cascading Style Sheet (CSS) language. An appealing feature of CSS is that it specifies formatting instructions using rather simple guarded rules. A limitation of CSS is that it focuses on static formatting rules. As a consequence scripting languages such as ECMA Script are used in practice for dynamic adaptation of formatting. CSS NG is a novel extension of CSS 3, the newest version of CSS, introducing just a few rules for a dynamic rendering and for markup visualization. This limited extension of CSS 3 turns out to make possible a rather advanced visualization of programs. This article (1) introduces into the extensions of CSS NG with respect to CSS 3, (2) describes a proof-of-concept prototype implementation of CSS NG, and (3) demonstrates CSS NG on Xcerpt query programs. 1

MPI-hybrid Parallelism for Volume Rendering on Large, Multi-core Systems  

Science Conference Proceedings (OSTI)

This work studies the performance and scalability characteristics of"hybrid'" parallel programming and execution as applied to raycasting volume rendering -- a staple visualization algorithm -- on a large, multi-core platform. Historically, the Message Passing Interface (MPI) has become the de-facto standard for parallel programming and execution on modern parallel systems. As the computing industry trends towards multi-core processors, with four- and six-core chips common today and 128-core chips coming soon, we wish to better understand how algorithmic and parallel programming choices impact performance and scalability on large, distributed-memory multi-core systems. Our findings indicate that the hybrid-parallel implementation, at levels of concurrency ranging from 1,728 to 216,000, performs better, uses a smaller absolute memory footprint, and consumes less communication bandwidth than the traditional, MPI-only implementation.

Hybrid Parallelism for Volume Rendering on Large, Multi- and Many-core Systems  

SciTech Connect

With the computing industry trending towards multi- and many-core processors, we study how a standard visualization algorithm, ray-casting volume rendering, can benefit from a hybrid parallelism approach. Hybrid parallelism provides the best of both worlds: using distributed-memory parallelism across a large numbers of nodes increases available FLOPs and memory, while exploiting shared-memory parallelism among the cores within each node ensures that each node performs its portion of the larger calculation as efficiently as possible. We demonstrate results from weak and strong scaling studies, at levels of concurrency ranging up to 216,000, and with datasets as large as 12.2 trillion cells. The greatest benefit from hybrid parallelism lies in the communication portion of the algorithm, the dominant cost at higher levels of concurrency. We show that reducing the number of participants with a hybrid approach significantly improves performance.

Graphical technique for interpolating shape factors for peripheral waterflood systems  

SciTech Connect

A method of interpolating the shape factors between already known sets of data can be utilized in peripheral waterflood systems. This graphical technique should provide reasonably reliable shape factors without necessitating further flow pattern evaluation. A set of interpolated shape factors for the constant pressure difference case is tabulated. These factors were derived from the shape factors previously determined using variation of width technique. A comparison of the interpolated shape factors and the shape factors obtained by the circling-in techniques are also shown. Good agreement was obtained in this comparison.

In a recommendation system, customers' preferences are encoded into vectors, and finding the nearest vectors to each vector is an essential part. We define this part of problem as a $k$-nearest vector problem and give an effective algorithm to solve it on multiple graphics processor units (GPUs). By an experiment, we show that when the size of the problem is large, an implementation of the algorithm on two GPUs runs more than 260 times faster than a single core implementation on a latest CPU. We also show that our algorithm scales well with respect to the number of GPUs.

Abstract. The database usability experience has shown that visual query languages tend to be superior to textual languages in many aspects. By applying this principle in the context of ontologies, we present GLOO, a graphical query language for OWL-DL ontologies. GLOO maps diagrammatic queries to DL based query languages such as nRQL, which is offered by the OWL-DL reasoner Racer. GLOO hides the complexity of a DL query language from users and allows them to query OWL ontologies with less difficulty. 1

Prefiltered B-Spline Reconstruction for Hardware-Accelerated Rendering of Optimally Sampled Volumetric Data  

E-Print Network (OSTI)

In this paper odd-order B-spline filters are proposed to reconstruct volumetric data sampled on an optimal Body-Centered Cubic (BCC) grid. To make these filters nearly interpolating, we adapt a previously published framework, which is based on a discrete frequency-domain prefiltering. It is shown that a BCC-sampled B-spline kernel is not invertible, therefore the interpolation constraint cannot be satisfied by a discrete prefiltering. To remedy this problem, we use a slightly modified discrete Bspline for prefiltering, which is proven to be invertible. Although this modification leads to an approximation, the proposed prefiltered B-spline reconstruction of BCC-sampled data still provides much higher image quality than the interpolating prefiltered B-spline reconstruction of volume data sampled on an equivalent Cartesian Cubic (CC) grid. Furthermore, our method directly supports an efficient implementation on a conventional graphics hardware, unlike the previous reconstruction methods developed for the BCC grid.

A Graphic Representation of States for Quantum Copying Machines  

E-Print Network (OSTI)

The aim of this paper is to introduce a new graphic representation of quantum states by means of a specific application: the analysis of two models of quantum copying machines. The graphic representation by diagrams of states offers a clear and detailed visualization of quantum information's flow during the unitary evolution of not too complex systems. The diagrams of states are exponentially more complex in respect to the standard representation and this clearly illustrates the discrepancy of computational power between quantum and classical systems. After a brief introductive exposure of the general theory, we present a constructive procedure to illustrate the new representation by means of concrete examples. Elementary diagrams of states for single-qubit and two-qubit systems and a simple scheme to represent entangled states are presented. Quantum copying machines as imperfect cloners of quantum states are introduced and the quantum copying machines of Griffiths and Niu and of Buzek and Hillery are analyzed, determining quantum circuits of easier interpretation. The method has indeed shown itself to be extremely successful for the representation of the involved quantum operations and it has allowed to point out the characteristic aspects of the quantum computations examined.

SciTech Connect

Scientific visualization is playing an increasingly important role in the analysis and interpretation of massively parallel CFD simulations due to the enormous volume of data that can be generated on these machines. In this paper we will describe the development of a visualization technique based on a parallel analogue to the Marching Cubes algorithm. The algorithm has been developed for Multiple-Instruction, Multiple-Data (MIMD) massively parallel computers and is designed to take advantage of the heterogeneous programming capabilities of the MIMD architecture. We examine several different configurations and conclude that for producing animations the best one, in terms of both frame generation time and disk usage, is to run the two applications heterogeneously and send the resulting geometry description directly to a workstation for rendering, thereby totally eliminating the use of files from the animation process.

Energy-Efficient, High-Color-Rendering LED Lamps Using Oxyfluoride and Fluoride Phosphors  

Science Conference Proceedings (OSTI)

LED lamps using phosphor downconversion can be designed to replace incandescent or halogen sources with a 'warm-white' correlated color temperature (CCT) of 2700-3200 K and a color rendering index (CRI) greater than 90. However, these lamps have efficacies of {approx}70% of standard 'cool-white' LED packages (CCT = 4500-6000 K; CRI = 75-80). In this report, we describe structural and luminescence properties of fluoride and oxyfluoride phosphors, specifically a (Sr,Ca){sub 3}(Al,Si)O{sub 4}(F,O):Ce{sup 3+} yellow-green phosphor and a K{sub 2}TiF{sub 6}:Mn{sup 4+} red phosphor, that can reduce this gap and therefore meet the spectral and efficiency requirements for high-efficacy LED lighting. LED lamps with a warm-white color temperature (3088 K), high CRI (90), and an efficacy of {approx}82 lm/W are demonstrated using these phosphors. This efficacy is {approx}85% of comparable cool-white lamps using typical Y{sub 3}Al{sub 5}O{sub 12}:Ce{sup 3+}-based phosphors, significantly reducing the efficacy gap between warm-white and cool-white LED lamps that use phosphor downconversion.

Dynamic Decision Making for Graphical Models Applied to Oil Exploration  

E-Print Network (OSTI)

We present a framework for sequential decision making in problems described by graphical models. The setting is given by dependent discrete random variables with associated costs or revenues. In our examples, the dependent variables are the potential outcomes (oil, gas or dry) when drilling a petroleum well. The goal is to develop an optimal selection strategy that incorporates a chosen utility function within an approximated dynamic programming scheme. We propose and compare different approximations, from simple heuristics to more complex iterative schemes, and we discuss their computational properties. We apply our strategies to oil exploration over multiple prospects modeled by a directed acyclic graph, and to a reservoir drilling decision problem modeled by a Markov random field. The results show that the suggested strategies clearly improve the simpler intuitive constructions, and this is useful when selecting exploration policies.

Yasso07 is applicable to upland soils of different ecosystems worldwide, because it has been developed using data covering the global climate conditions and representing various ecosystem types. As input information, Yasso07 requires data on litter input to soil, climate conditions, and land-use change if any. The model predictions are given as probability densities representing the uncertainties in the parameter values of the model and those in the input data - the user interface calculates these densities using a built-in Monte Carlo simulation.

Molecular Dynamics Simulation of Macromolecules Using Graphics Processing Unit  

E-Print Network (OSTI)

Molecular dynamics (MD) simulation is a powerful computational tool to study the behavior of macromolecular systems. But many simulations of this field are limited in spatial or temporal scale by the available computational resource. In recent years, graphics processing unit (GPU) provides unprecedented computational power for scientific applications. Many MD algorithms suit with the multithread nature of GPU. In this paper, MD algorithms for macromolecular systems that run entirely on GPU are presented. Compared to the MD simulation with free software GROMACS on a single CPU core, our codes achieve about 10 times speed-up on a single GPU. For validation, we have performed MD simulations of polymer crystallization on GPU, and the results observed perfectly agree with computations on CPU. Therefore, our single GPU codes have already provided an inexpensive alternative for macromolecular simulations on traditional CPU clusters and they can also be used as a basis to develop parallel GPU programs to further speedup the computations.

Polymer Field-Theory Simulations on Graphics Processing Units  

E-Print Network (OSTI)

We report the first CUDA graphics-processing-unit (GPU) implementation of the polymer field-theoretic simulation framework for determining fully fluctuating expectation values of equilibrium properties for periodic and select aperiodic polymer systems. Our implementation is suitable both for self-consistent field theory (mean-field) solutions of the field equations, and for fully fluctuating simulations using the complex Langevin approach. Running on NVIDIA Tesla T20 series GPUs, we find double-precision speedups of up to 30x compared to single-core serial calculations on a recent reference CPU, while single-precision calculations proceed up to 60x faster than those on the single CPU core. Due to intensive communications overhead, an MPI implementation running on 64 CPU cores remains two times slower than a single GPU.

A graphics processor-based intranuclear cascade and evaporation simulation  

E-Print Network (OSTI)

Monte Carlo simulations of the transport of protons in human tissue have been deployed on graphics processing units (GPUs) with impressive results. To provide a more complete treatment of non-elastic nuclear interactions in these simulations, we developed a fast intranuclear cascade-evaporation simulation for the GPU. This can be used to model non-elastic proton collisions on any therapeutically relevant nuclei at incident energies between 20 and 250 MeV. Predictions are in good agreement with Geant4.9.6p2. It takes approximately 2 s to calculate $1\\times 10^6$ 200 MeV proton-$^{16}$O interactions on a NVIDIA GTX680 GPU. A speed-up factor of $\\sim$20 relative to one Intel i7-3820 core processor thread was achieved.

Incorporating Perceptual Task Effort into the Recognition of Intention in Information Graphics  

E-Print Network (OSTI)

The rapidly increasing availability of electronic publications containing information graphics poses some interesting challenges in terms of information access. For example, visually impaired individuals should ideally be provided with access to the knowledge that would be gleaned from viewing the information graphic. Similarly, digital libraries must take into account the content of information graphics when constructing indices. This paper outlines our approach to recognizing the intended message of an information graphic, focusing on the concept of perceptual task e#ort, its role in the inference process, our rules for estimating e#ort, and the results of an eye tracking experiment conducted in order to evaluate and modify those rules.

Harmonic engine  

Science Conference Proceedings (OSTI)

A high efficiency harmonic engine based on a resonantly reciprocating piston expander that extracts work from heat and pressurizes working fluid in a reciprocating piston compressor. The engine preferably includes harmonic oscillator valves capable of oscillating at a resonant frequency for controlling the flow of working fluid into and out of the expander, and also preferably includes a shunt line connecting an expansion chamber of the expander to a buffer chamber of the expander for minimizing pressure variations in the fluidic circuit of the engine. The engine is especially designed to operate with very high temperature input to the expander and very low temperature input to the compressor, to produce very high thermal conversion efficiency.

Web-based Stereo Rendering for Visualization and Annotation of Scientific Volumetric Data  

E-Print Network (OSTI)

Advancement in high-throughput microscopy technology such as the Knife-Edge Scanning Microscopy (KESM) is enabling the production of massive amounts of high-resolution and high-quality volumetric data of biological microstructures. To fully utilize these data, they should be efficiently distributed to the scientific research community through the Internet and should be easily visualized, annotated, and analyzed. Given the volumetric nature of the data, visualizing them in 3D is important. However, since we cannot assume that every end user has high-end hardware, an approach that has minimal hardware and software requirements will be necessary, such as a standard web browser running on a typical personal computer. There are several web applications that facilitate the viewing of large collections of images. Google Maps and Google Maps-like interfaces such as Brainmaps.org allow users to pan and zoom 2D images efficiently. However, they do not yet support the rendering of volumetric data in their standard web interface. The goal of this thesis is to develop a light-weight volumetric image viewer using existing web technologies such as HTML, CSS and JavaScript while exploiting the properties of stereo vision to facilitate the viewing and annotations of volumetric data. The choice of stereogram over other techniques was made since it allows the usage of raw image stacks produced by the 3D microscope without any extra computation on the data at all. Operations to generate stereo images using 2D image stacks include distance attenuation and binocular disparity. By using HTML and JavaScript that are computationally cheap, we can accomplish both tasks dynamically in a standard web browser, by overlaying the images with intervening semi-opaque layers. The annotation framework has also been implemented and tested. In order for annotation to work in this environment, it should also be in the form of stereogram and should aid the merging of stereo pairs. The current technique allows users to place a mark (dot) on one image stack, and its projected position onto the other image stack is calculated dynamically on the client side. Other extra metadata such as textual descriptions can be entered by the user as well. To cope with the occlusion problem caused by changes in the z direction, the structure traced by the user will be displayed on the side, together with the data stacks. Using the same stereo-gram creation techniques, the traces made by the user is dynamically generated and shown as stereogram. We expect the approach presented in this thesis to be applicable to a broader scientific domain, including geology and meteorology.

Optimized Phosphors for Warm White LED Light Engines  

Science Conference Proceedings (OSTI)

The objective of this program is to develop phosphor systems and LED light engines that have steady-state LED efficacies (using LEDs with a 60% wall-plug efficiency) of 105–120 lm/W with correlated color temperatures (CCT) ~3000 K, color rendering indices (CRI) >85, <0.003 distance from the blackbody curve (dbb), and <2% loss in phosphor efficiency under high temperature, high humidity conditions. In order to reach these goals, this involves the composition and processing optimization of phosphors previously developed by GE in combination with light engine package modification.

Langevin dynamics simulations of biomolecules on graphics processors  

E-Print Network (OSTI)

Due to the very long timescales involved (us-s), theoretical modeling of fundamental biological processes including folding, misfolding, and mechanical unraveling of biomolecules, under physiologically relevant conditions, is challenging even for distributed computing systems. Graphics Processing Units (GPUs) are emerging as an alternative programming platform to the more traditional CPUs as they provide high raw computational power that can be utilized in a wide range of scientific applications. Using a coarse-grained Self Organized Polymer (SOP) model, we have developed and tested the GPU-based implementation of Langevin simulations for proteins (SOP-GPU program). Simultaneous calculation of forces for all particles is implemented using either the particle based or the interacting pair based parallelization, which leads to a ~30-fold acceleration compared to an optimized CPU version of the program. We assess the computational performance of an end-to-end application of the SOP-GPU program, where all steps of the algorithm are running on the GPU, by profiling the associated simulation time and memory usage for a number of small proteins, long protein fibers, and large-size protein assemblies. The SOP-GPU package can now be used in the theoretical exploration of the mechanical properties of large-size protein systems to generate the force-extension and force-indentation profiles under the experimental conditions of force application, and to relate the results of single-molecule experiments in vitro and in silico.

Graphical Method for Effective Interaction with a New Vertex Function  

E-Print Network (OSTI)

Introducing a new vertex function, Z(E), of an energy variable E, we derive a new equation for the effective interaction. The equation is obtained by replacing the Q-box in the Krenciglowa-Kuo (KK) method by Z(E). This new approach can be viewed as an extension of the KK method. We show that this equation can be solved both in iterative and non-iterative ways. We observe that the iteration procedure with Z(E) brings about fast convergence compared to the usual KK method. It is shown that, as in the KK approach, the procedure of calculating the effective interaction can be reduced to determining the true eigenvalues of the original Hamiltonian H and they can be obtained as the positions of intersections of graphs generated from Z(E). We find that this graphical method yields always precise results and reproduces any of the true eigenvalues of H. The calculation in the present approach can be made regardless of overlaps with the model space and energy differences between unperturbed energies and the eigenvalues of H. We find also that Z(E) is a well-behaved function of E and has no singularity. These characteristics of the present approach ensure stability in actual calculations and would be helpful to resolve some difficulties due to the presence of poles in the Q-box. Performing test calculations we verify numerically theoretical predictions made in the present approach.

FLOCKING-BASED DOCUMENT CLUSTERING ON THE GRAPHICS PROCESSING UNIT  

Science Conference Proceedings (OSTI)

Analyzing and grouping documents by content is a complex problem. One explored method of solving this problem borrows from nature, imitating the fl ocking behavior of birds. Each bird represents a single document and fl ies toward other documents that are similar to it. One limitation of this method of document clustering is its complexity O(n2). As the number of documents grows, it becomes increasingly diffi cult to receive results in a reasonable amount of time. However, fl ocking behavior, along with most naturally inspired algorithms such as ant colony optimization and particle swarm optimization, are highly parallel and have experienced improved performance on expensive cluster computers. In the last few years, the graphics processing unit (GPU) has received attention for its ability to solve highly-parallel and semi-parallel problems much faster than the traditional sequential processor. Some applications see a huge increase in performance on this new platform. The cost of these high-performance devices is also marginal when compared with the price of cluster machines. In this paper, we have conducted research to exploit this architecture and apply its strengths to the document flocking problem. Our results highlight the potential benefi t the GPU brings to all naturally inspired algorithms. Using the CUDA platform from NVIDIA®, we developed a document fl ocking implementation to be run on the NVIDIA® GEFORCE 8800. Additionally, we developed a similar but sequential implementation of the same algorithm to be run on a desktop CPU. We tested the performance of each on groups of news articles ranging in size from 200 to 3,000 documents. The results of these tests were very signifi cant. Performance gains ranged from three to nearly fi ve times improvement of the GPU over the CPU implementation. This dramatic improvement in runtime makes the GPU a potentially revolutionary platform for document clustering algorithms.

Computer graphics at Oak Ridge National Laboratory: some observations based on experience  

SciTech Connect

This paper focuses upon explaining six conclusions concerning what the author considers to be an appropriate philosophy toward developing computer graphics software, particularly computer mapping. In summary, the conclusions are that computer mapping software should not be developed apart from the researcher or analyst and that those efforts developed apart tend to be esoteric in nature. Three examples involving regional energy modeling and related impact assessment are used to illustrate how development of computer graphics should be integrated into research involving geographical analysis.

Engines - Spark Ignition Engines - Direct Injection - Omnivorous Engine  

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

Direct Injection, Spark-Ignited Engines Direct Injection, Spark-Ignited Engines Omnivorous Engine Omnivorous Engine Setup Omnivorous Engine Setup New engine technology has made possible engines that will operate on a wide variety of fuel inputs, from gasoline to naptha to ethanol to methanol, without driver intervention. Although flexible fuel vehicles have been produced in the millions, their engines have always been optimized for gasoline operation while accepting significant performance and efficiency degradations when using the alternative fuel. This project seeks to combine in-cylinder measurement technology, and advanced controls to optimize spark timing, the quantity and timing of injected fuel, to produce an "omnivorous engine"--one that will be able to run on any liquid spark ignition fuel with optimal efficiency and low

Multimedia Feedback Systems for Engineering  

SciTech Connect

The World Wide Web has become a key tool for information sharing. Engineers and scientists are finding that the web is especially suited to publishing the graphical, multi-layered information that is typical of their work. Web pages are easier to distribute than hardcopy. Web movies have become more accessible, in many offices, than videos. Good VRML viewing software, bundled with most new PCs, has sufficient power to support many engineering needs. In addition to publishing information science and engineering has an important tradition of peer and customer review. Reports, drawings and graphs are typically printed, distributed, reviewed, marked up, and returned to the author. Adding review comments to paper is easy. When, however, the information is in electronic form, this ease of review goes away. It's hard to write on videos. It's even harder to write comments on animated 3D models. These feedback limitations reduce the value of the information overall. Fortunately, the web can also be a useful tool for collecting peer and customer review information. When properly formed, web reports, movies, and 3D animations can be readily linked to review notes. This paper describes three multimedia feed-back systems that Sandia National Laboratories has developed to tap that potential. Each system allows people to make context-sensitive comments about specific web content and electronically ties the comments back to the web content being referenced. The fuel system ties comments to specific web pages, the second system ties the comments to specific frames of digital movies, and the third ties the comments to specific times and viewpoints within 3D animations. In addition to the technologies, this paper describes how they are being used to support intelligent machine systems design at Sandia.

Interactive statistical-distribution-analysis program utilizing numerical and graphical methods  

SciTech Connect

The TERPED/P program is designed to facilitate the quantitative analysis of experimental data, determine the distribution function that best describes the data, and provide graphical representations of the data. This code differs from its predecessors, TEDPED and TERPED, in that a printer-plotter has been added for graphical output flexibility. The addition of the printer-plotter provides TERPED/P with a method of generating graphs that is not dependent on DISSPLA, Integrated Software Systems Corporation's confidential proprietary graphics package. This makes it possible to use TERPED/P on systems not equipped with DISSPLA. In addition, the printer plot is usually produced more rapidly than a high-resolution plot can be generated. Graphical and numerical tests are performed on the data in accordance with the user's assumption of normality or lognormality. Statistical analysis options include computation of the chi-squared statistic and its significance level and the Kolmogorov-Smirnov one-sample test confidence level for data sets of more than 80 points. Plots can be produced on a Calcomp paper plotter, a FR80 film plotter, or a graphics terminal using the high-resolution, DISSPLA-dependent plotter or on a character-type output device by the printer-plotter. The plots are of cumulative probability (abscissa) versus user-defined units (ordinate). The program was developed on a Digital Equipment Corporation (DEC) PDP-10 and consists of 1500 statements. The language used is FORTRAN-10, DEC's extended version of FORTRAN-IV.

A Tcl/Tk-based, intelligent graphical editor for preparing HST programs  

E-Print Network (OSTI)

. The Space Telescope Science Institute (STScI) built the Proposal Editor (PED) system to be an intelligent graphical editor for creating a detailed observing program for the Hubble Space Telescope (HST). Previously, users would type in an observing program in a text editor, and then essentially compile it to check for errors. PED gives users an interactive session that provides menus and selections whenever possible, eliminating many possible errors resulting from typos. Multiple choice selections include the invalid values with explanations as to why they are invalid. A declarative constraint mechanism is used to encode legal and illegal values for individual program parts as well as relationships between parts. Error checking is provided on individual parts, as well as on the program as a whole. 1. Introduction The PED system was developed in order to provide an interactive tool for investigators to create their detailed observing programs. It is essentially a graphical interface ...

Graphical Analysis of PET Data Applied to Reversible and Irreversible Tracers  

SciTech Connect

Graphical analysis refers to the transformation of multiple time measurements of plasma and tissue uptake data into a linear plot, the slope of which is related to the number of available tracer binding sites. This type of analysis allows easy comparisons among experiments. No particular model structure is assumed, however it is assumed that the tracer is given by bolus injection and that both tissue uptake and the plasma concentration of unchanged tracer are monitored following tracer injection. The requirement of plasma measurements can be eliminated in some cases when a reference region is available. There are two categories of graphical methods which apply to two general types of ligands--those which bind reversibly during the scanning procedure and those which are irreversible or trapped during the time of the scanning procedure.

Quasi-real-time analysis of dynamic near field scattering data using a graphics processing unit  

E-Print Network (OSTI)

We present an implementation of the analysis of dynamic near field scattering (NFS) data using a graphics processing unit (GPU). We introduce an optimized data management scheme thereby limiting the number of operations required. Overall, we reduce the processing time from hours to minutes, for typical experimental conditions. Previously the limiting step in such experiments, the processing time is now comparable to the data acquisition time. Our approach is applicable to various dynamic NFS methods, including shadowgraph, Schlieren and differential dynamic microscopy.

Optimized hydrogen piston engines  

DOE Green Energy (OSTI)

Hydrogen piston engines can be simultaneously optimized for improved thermal efficiency and for extremely low emissions. Using these engines in constant-speed, constant-load systems such as series hybrid-electric automobiles or home cogeneration systems can result in significantly improved energy efficiency. For the same electrical energy produced, the emissions from such engines can be comparable to those from natural gas-fired steam power plants. These hydrogen-fueled high-efficiency, low-emission (HELE) engines are a mechanical equivalent of hydrogen fuel cells. HELE engines could facilitate the transition to a hydrogen fuel cell economy using near-term technology.

A Parallel Implementation of a Smoothed Particle Hydrodynamics Method on Graphics Hardware Using the Compute Unified Device Architecture  

Science Conference Proceedings (OSTI)

The smoothed particle hydrodynamics (SPH), which is a class of meshfree particle methods (MPMs), has a wide range of applications from micro-scale to macro-scale as well as from discrete systems to continuum systems. Graphics hardware, originally designed for computer graphics, now provide unprecedented computational power for scientific computation. Particle system needs a huge amount of computations in physical simulation. In this paper, an efficient parallel implementation of a SPH method on graphics hardware using the Compute Unified Device Architecture is developed for fluid simulation. Comparing to the corresponding CPU implementation, our experimental results show that the new approach allows significant speedups of fluid simulation through handling huge amount of computations in parallel on graphics hardware.
