Introduction to Graphical Modelling
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.

Graphics Turing Test
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

Graphical amplitudes from SCET
We discuss the relationship between the graphical amplitudes T, C, P, ... used to parameterize nonleptonic B decay amplitudes, and matrix elements of operators in the soft-collinear effective theory (SCET) at leading order in \\Lambda/m_b. Using the SU(3) flavor symmetry of the weak Hamiltonian we derive all-order constraints on the electroweak penguin contributions to the Wilson coefficients of SCET operators.

Teaching Computer Graphics in Brazil
. We present in this panel a collection of views and experiences about computer graphics teaching and education in Brazil. We hope this discussion will further development of guidelines and teaching materials for computer graphics curricula and courses. 1 Introduction The activities related with Computer Graphics Teaching in Brazil have received relatively little attention and discussion from the Computer Graphics Academic Community. On one hand we have a strong research community mature enough to deserve international recognition [8]. On the other hand it seems we are not paying enough attention to discuss issues related with teaching computer graphics, in spite of individual efforts [1]. This panel aims to be a forum for discussions on various issues related with Computer Graphics Teaching in Brazil. In general terms the main goals of this panel are: ffl To discuss the syllabi for introductory computer science graphics courses ffl To identify a set of most-commonly taught co...

Graphical Representation of Supersymmetry
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.

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.

Extending Document Summarization to Information Graphics
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
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.

A Visual Agent for Performance Graphics
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...

Graphical representation of generalized quantum measurements
We present graphical representation for genaralized quantum measurements (POVM). We represent POVM elements as Bloch vectors and find the conditions these vectors should satisfy in order to describe realizable physical measurements. We show how to find probability of measurement outcome in a graphical way. The whole formalism is applied to unambigous discrimination of nonorthogonal quantum states.

Customising Graphics Applications: Techniques and Programming Interface
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...

Applying Object-Oriented Design to Structured Graphics
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...

Graphical calculus for Gaussian pure states
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.

An apparatus for generating raster graphics images from the graphics command stream includes a plurality of graphics processors connected in parallel, each adapted to receive any part of the graphics command stream for processing the command stream part into pixel data. The apparatus also includes a frame buffer for mapping the pixel data to pixel locations and an interconnection network for interconnecting the graphics processors to the frame buffer. Through the interconnection network, each graphics processor may access any part of the frame buffer concurrently with another graphics processor accessing any other part of the frame buffer. The plurality of graphics processors can thereby transmit concurrently pixel data to pixel locations in the frame buffer.

Graphical Representation of SUSY and Application to QFT
We present a graphical representation of the supersymmetry and the graphical calculation. Calculation is demonstrated for 4D Wess-Zumino model and for Super QED. The chiral operators are graphically expressed in an illuminating way. The tedious part of SUSY calculation, due to manipulating chiral suffixes, reduces considerably. The application is diverse.

Research Statement: Multiresolution in Graphics and Simulation
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. Figure 1: Example applications which benefit from our multiresolution s

Scientific statistics and graphics on the Macintosh
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.

Harvesting graphics power for MD simulations
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
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.
Monte Carlo simulations on Graphics Processing Units
Implementation of basic local Monte-Carlo algorithms on ATI Graphics Processing Units (GPU) is investigated. The Ising model and pure SU(2) gluodynamics simulations are realized with the Compute Abstraction Layer (CAL) of ATI Stream environment using the Metropolis and the heat-bath algorithms, respectively. We present an analysis of both CAL programming model and the efficiency of the corresponding simulation algorithms on GPU. In particular, the significant performance speed-up of these algorithms in comparison with serial execution is observed.

Data Reduction and Analysis Graphical Organizer
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
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
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
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.

Fast DRR splat rendering using common consumer graphics hardware
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.

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.

Quantum Graphical Models and Belief Propagation
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.

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.

New method for abbreviating the fault tree graphical representation
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)

A Graphical representation of the grand canonical partition function
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.

A C-Based Graphics Library for CS1
This paper describes a simple graphics library designed for a CS1 course using ANSI C as its programming language. The library can be implemented easily on a variety of hardware platforms, providing a reasonable level of portability. Implementations currently exist for compilers on the Apple Macintosh, the IBM PC, and Unix workstations; the source code for each of these implementations is publicly available by anonymous FTP from the aw.computer.science/Roberts.CS1.C area on host aw.com. In addition, the public distribution includes a fully standard implementation that generates a PostScript representation of the graphical image.

Graphical functions and single-valued multiple polylogarithms
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
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
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.

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

Computing trends using graphic processor in high energy physics
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
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.

An Alternate Graphical Representation of Periodic table of Chemical Elements
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
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

of 10: the case for changing the first course in computer graphics
The growing maturity of computer graphics technology now makes it possible to view the introductory graphics course in a general computer science curriculum in a new light. Instead of requiring highly specialized techniques and a great deal of mathematics before a student can produce significant work, the course can now be built around generally-accepted standard graphics standard APIs. This opens the door to making computer graphics available to a wider audience and moves the introductory computer graphics course in exciting new directions. 1

Graphical technique for interpolating shape factors for peripheral waterflood systems
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.

Resolution-independent surface rendering using programmable graphics hardware
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.

V.: GLOO: A Graphical Query Language for OWL Ontologies. OWLED
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

Solving $k$-Nearest Vector Problem on Multiple Graphics Processors
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.

A Graphic Representation of States for Quantum Copying Machines
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.

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

Molecular Dynamics Simulation of Macromolecules Using Graphics Processing Unit
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
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
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.

Soil carbon model Yasso07 graphical user interface
In this article, we present a graphical user interface software for the litter decomposition and soil carbon model Yasso07 and an overview of the principles and formulae it is based on. The software can be used to test the model and use it in simple applications. 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.

Dynamic Decision Making for Graphical Models Applied to Oil Exploration
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.

Langevin dynamics simulations of biomolecules on graphics processors
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
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.

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
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.

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

A Survey of Ocean Simulation and Rendering Techniques in Computer Graphics
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.

Graphical Analysis of PET Data Applied to Reversible and Irreversible Tracers
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
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.

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

An evolving infrastructure for scientific computing and the integration of new graphics technology
The National Energy Research Supercomputer Center (NERSC) at the Lawrence Livermore National Laboratory is currently pursuing several projects to implement and integrate new hardware and software technologies. While each of these projects ought to be and is in fact individually justifiable, there is an appealing metaphor for viewing them collectively which provides a simple and memorable way to understand the future direction not only of supercomputing services but of computer centers in general. Once this general direction is understood, it becomes clearer what future computer graphics technologies would be possible and desirable, at least within the context of large scale scientific computing.

The Chamomile Scheme: An Optimized Algorithm for N-body simulations on Programmable Graphics Processing Units
We present an algorithm named "Chamomile Scheme". The scheme is fully optimized for calculating gravitational interactions on the latest programmable Graphics Processing Unit (GPU), NVIDIA GeForce8800GTX, which has (a) small but fast shared memories (16 K Bytes * 16) with no broadcasting mechanism and (b) floating point arithmetic hardware of 500 Gflop/s but only for single precision. Based on this scheme, we have developed a library for gravitational N-body simulations, "CUNBODY-1", whose measured performance reaches to 173 Gflop/s for 2048 particles and 256 Gflop/s for 131072 particles.

Pseudo-random number generators for Monte Carlo simulations on Graphics Processing Units
Basic uniform pseudo-random number generators are implemented on ATI Graphics Processing Units (GPU). The performance results of the realized generators (multiplicative linear congruential (GGL), XOR-shift (XOR128), RANECU, RANMAR, RANLUX and Mersenne Twister (MT19937)) on CPU and GPU are discussed. The obtained speed-up factor is hundreds of times in comparison with CPU. RANLUX generator is found to be the most appropriate for using on GPU in Monte Carlo simulations. The brief review of the pseudo-random number generators used in modern software packages for Monte Carlo simulations in high-energy physics is present.

The web-based graphic service request system for facility management of apartments
This research investigates the feasibility of web technology as a means of handling service requests for delivering high quality service in building operation and maintenance. This research proposes a web-based graphic service request (WGSR) system as a pragmatic solution to the limitations of current computerized maintenance management system (CMMS) processes. Service request process in CMMS was developed as text-based, so that it is hard for ordinary tenants to use. Therefore, when tenants have a problem in a facility, they prefer calling in service requests or going to the office instead of using the internet service request application. In practice, work orders and records are often misplaced - resulting in lower efficiency and customer satisfaction. This may be overcome by a system that states information digitally and provides a web-based Graphic Service Request (WGSR) interface. The interface allow customers to report environmental problems in the facility, trace their work order progress, view schedules for maintenance, and provide feedback for service online. The WGSR system is an end-user point-and-click graphical interface that allows residents to request service by selecting a problem fixture on a floor plan image. By using HTML image map tags and combination of location, part, and types of problem identification number, the resident's input produces a text-based problem report for Facility Management (FM) departments that allows them to service requests on the fly. To solve the complexity and inefficiency issues of CMMS, the user interface for the WGRS system consists of a perspective drawing or isometric drawing of each unit's plan. An empirical test of the system and post-task survey was conducted to determine the efficiency and usefulness of the system. The analysis of the results shows the system to be efficient and convenient in several fields, including comprehensibility, navigability, simplicity, clarity, compatibility, and graphic appeal. This result shows that residents prefer to use the WGSR system and could reduce the effort needed to make and receive service request phone calls and input information into a database. The labor and time for daily work could be saved to recognize problems correctly and set the right schedule so that this could be used for preventive work and project work.

SpectroWeb: An Interactive Graphical Database of Digital Stellar Spectral Atlases
SpectroWeb is an online maintained interactive graphical database of digital spectral atlases of spectral standard stars at http://spectra.freeshell.org . It is an efficient and user-friendly research tool for accurate analyses of stellar spectra observed with large spectral resolution, including the solar spectrum. The web-interface displays observed and theoretical stellar spectra, and comprehensively provides detailed atomic and molecular line information via user interaction. It fully integrates interactive spectrum visualization tools for the analysis, management, and maintenance of large volumes of spectral line-identification, -transition, and -property data. SpectroWeb 1.0 currently offers optical (3300-6800 A) flux normalized high-resolution spectra of Betelgeuse (M2), Arcturus (K1), The Sun (G2), Beta Aqr (G0), Procyon (F5), and Canopus (F0). The provided line identifications are based on state of the art spectrum synthesis calculations. The graphical database is under permanent development as an online repository of identified (absorption) lines in spectral standard reference stars, covering a broad range of stellar spectral types. Its object-oriented (Java) implementation offers future expansion capabilities to link and read stellar spectral atlases from various public internet sites.

Graphic-Card Cluster for Astrophysics (GraCCA) -- Performance Tests
In this paper, we describe the architecture and performance of the GraCCA system, a Graphic-Card Cluster for Astrophysics simulations. It consists of 16 nodes, with each node equipped with 2 modern graphic cards, the NVIDIA GeForce 8800 GTX. This computing cluster provides a theoretical performance of 16.2 TFLOPS. To demonstrate its performance in astrophysics computation, we have implemented a parallel direct N-body simulation program with shared time-step algorithm in this system. Our system achieves a measured performance of 7.1 TFLOPS and a parallel efficiency of 90% for simulating a globular cluster of 1024K particles. In comparing with the GRAPE-6A cluster at RIT (Rochester Institute of Technology), the GraCCA system achieves a more than twice higher measured speed and an even higher performance-per-dollar ratio. Moreover, our system can handle up to 320M particles and can serve as a general-purpose computing cluster for a wide range of astrophysics problems.

The Geant4 Visualisation System - a multi-driver graphics system
From the beginning the Geant4 Visualisation System was designed to support several simultaneous graphics systems written to common abstract interfaces. Today it has matured into a powerful diagnostic and presentational tool. It comes with a library of models that may be added to the current scene and which include the representation of the Geant4 geometry hierarchy, simulated trajectories and user-written hits and digitisations. The workhorse is the OpenGL suite of drivers for X, Xm, Qt and Win32. There is an Open Inventor driver. Scenes can be exported in special graphics formats for offline viewing in the DAWN, VRML, HepRApp and gMocren browsers. PostScript can be generated through OpenGL, Open Inventor, DAWN and HepRApp. Geant4's own tracking algorithms are used by the Ray Tracer. Not all drivers support all features but all drivers bring added functionality of some sort. This paper describes the interfaces and details the individual drivers.

Real Time Simulation and Visualization of NC Milling Processes for Inhomogeneous Materials on Low-End Graphics Hardware
Simulation and visualization of NC milling processes has become an important step in computer aided manufacturing. The usage of stock materials with specific locally varying properties (like density, accuracy, color,. . . ) becomes more and more important with new technologies emerging in the material industry. Our new approach, using volumetric representation, has been adapted to this needs and copes with inhomogeneous material properties. Taking color as one possible material property, our approach enables the visualization of milled wood or compound materials. Furthermore, our approach has been developed with the usage of low-end graphics hardware in mind. The algorithms have been optimized to ensure interactive update rates even on standard personal computers without hardware graphics acceleration. Keywords: NC milling simulation, dexel approach, inhomogeneous material properties 1. Introduction NC milling simulation using computer graphics techniques was proposed some years ag...

Graphical History List with Multi-Window Support on a Mobile Web Browser
Rolling back to previously visited Web pages and opening multiple browser windows or tabs at the same time are common activities in a Web browsing session on a PC. When using a mobile device for Web browsing, these usage patterns have to be supported seamlessly in the mobile environment under the additional constraint of limited screen real estate. In this paper, we introduce a solution called Rolling History, a user interface targeted for mobile devices with 4-way navigation control and graphics acceleration hardware. We tested the usefulness of a Rolling History prototype in two small-scale user studies and the results indicate that Rolling History is a useful feature for Web history navigation and browser windows management. The Rolling History case demonstrates how to design a unique user interface for a mobile device without displacing the deep-seated use patterns that people have found useful on a PC.

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

Graphical Calculus for the Double Affine Q-Dependent Braid Group
We define a double affine $Q$-dependent braid group. This group is constructed by appending to the braid group a set of operators $Q_i$, before extending it to an affine $Q$-dependent braid group. We show specifically that the elliptic braid group and the double affine Hecke algebra (DAHA) can be obtained as quotient groups. Complementing this we present a pictorial representation of the double affine $Q$-dependent braid group based on ribbons living in a toroid. We show that in this pictorial representation we can fully describe any DAHA. Specifically, we graphically describe the parameter $q$ upon which this algebra is dependent and show that in this particular representation $q$ corresponds to a twist in the ribbon.

I introduce a new code for fast calculation of the Lomb-Scargle periodogram that leverages the computing power of graphics processing units (GPUs). After establishing a background to the newly emergent field of GPU computing, I discuss the code design and narrate key parts of its source. Benchmarking calculations indicate no significant differences in accuracy compared to an equivalent CPU-based code. However, the differences in performance are pronounced; running on a low-end GPU, the code can match eight CPU cores, and on a high-end GPU it is faster by a factor approaching 30. Applications of the code include analysis of long photometric time series obtained by ongoing satellite missions and upcoming ground-based monitoring facilities, and Monte Carlo simulation of periodogram statistical properties.

Graphical description of the action of Clifford operators on stabilizer states
We introduce a graphical representation of stabilizer states and translate the action of Clifford operators on stabilizer states into graph operations on the corresponding stabilizer-state graphs. Our stabilizer graphs are constructed of solid and hollow nodes, with (undirected) edges between nodes and with loops and signs attached to individual nodes. We find that local Clifford transformations are completely described in terms of local complementation on nodes and along edges, loop complementation, and change of node type or sign. Additionally, we show that a small set of equivalence rules generates all graphs corresponding to a given stabilizer state; we do this by constructing an efficient procedure for testing the equality of any two stabilizer graphs.
Real-time geo-registration of imagery using COTS graphics processors
A method of performing real-time geo-registration of high-resolution digital imagery using existing graphics processing units (GPUs) already found in current personal computers, rather than the main central processing unit (CPU). Digital image data captured by a camera (along with inertial navigation system (INS) data associated with the image data) is transferred to and processed by the GPU to perform the calculations involved in transforming the captured image into a geo-rectified, nadir-looking image. By using the GPU, the order-of-magnitude increase in throughput over conventional software techniques makes real-time geo-registration possible without the significant cost of custom hardware solutions.

Graphical template software for accurate micromanipulation in a scanning electron microscope
Micromanipulation techniques in a scanning electron microscope (SEM) have been utilized for assembling micrometer-sized structures. The precision of the assembled microstructures has been limited by the poor accuracy of the SEM image. We have developed a software to assist the operator in the accurate assembly of microstructures in a SEM, in which computer-generated outlines of the target structure [graphical templates (GTs)] are superimposed on the monitor. The displayed GTs are distorted on the basis of the image properties of the SEM evaluated in advance. As a consequence, the operator can construct microstructures with a high precision only by maneuvering the manipulator so that the outline of each object perfectly overlaps the GT without any alteration of the electron optics or circuits for improving the image accuracy.

Position and Orientation Tracking System three-dimensional graphical user interface. CRADA final report
Under the Department of Energy`s Robotics Technology Development Program (RTDP) Tank Waste Retrieval (TWR) program, a major effort is under way to develop technology for remediating the waste in underground storage tanks that contain radioactive and hazardous waste. A large part of the program`s effort has gone towards development of remotely operable robotics equipment, including the Houdini Vehicle and the Position and Orientation Tracking System (POTS). Since planned operation of this equipment is to be completely remote, a significant effort is needed to ensure that operators have sufficient system information to operate the equipment efficiently and safely. ORNL developed POTS and RedZone Robotics, Inc. developed Houdini which can be operated together to provide both position and orientation descriptions of the Houdini vehicle, relative to a world reference frame, while operating inside an underground storage tank. The Houdini vehicle has been outfitted with an optical detection system that houses infrared detectors. The infrared detectors are part of the POTS tracking system. The sensors provide a set of timing pulses to the POTS control computer whenever a laser beam from one of the four POTS laser scanners strikes a detector. Using the pointing angle information from each POTS laser scanners, the POTS control computer is able to compute the pose of the Houdini vehicle at a rate of approximately 25 Hz. This information, along with the orientation of the Houdini`s Schilling Titan II robot arm, is used to present the pose information to the operator in a 3-D graphical user interface using software that has been developed by this Cooperative Research and Development Agreement (CRADA). The graphical display presents the data to the operator in a format that is readily understood. The equipment operators are able to use the information in real-time to enhance the operator`s ability to safely and efficiently control the remotely-operated vehicle.

The VVDS data reduction pipeline: introducing VIPGI, the VIMOS Interactive Pipeline and Graphical Interface
The VIMOS VLT Deep Survey (VVDS), designed to measure 150,000 galaxy redshifts, requires a dedicated data reduction and analysis pipeline to process in a timely fashion the large amount of spectroscopic data being produced. This requirement has lead to the development of the VIMOS Interactive Pipeline and Graphical Interface (VIPGI), a new software package designed to simplify to a very high degree the task of reducing astronomical data obtained with VIMOS, the imaging spectrograph built by the VIRMOS Consortium for the European Southern Observatory, and mounted on Unit 3 (Melipal) of the Very Large Telescope (VLT) at Paranal Observatory (Chile). VIPGI provides the astronomer with specially designed VIMOS data reduction functions, a VIMOS-centric data organizer, and dedicated data browsing and plotting tools, that can be used to verify the quality and accuracy of the various stages of the data reduction process. The quality and accuracy of the data reduction pipeline are comparable to those obtained using well known IRAF tasks, but the speed of the data reduction process is significantly increased, thanks to the large set of dedicated features. In this paper we discuss the details of the MOS data reduction pipeline implemented in VIPGI, as applied to the reduction of some 20,000 VVDS spectra, assessing quantitatively the accuracy of the various reduction steps. We also provide a more general overview of VIPGI capabilities, a tool that can be used for the reduction of any kind of VIMOS data.

AN ANALYSIS OF RESIDENTIAL RADON MEASUREMENTS IN KANSAS UTILIZING GRAPHICAL INFORMATION SYSTEM (GIs) TOOLS
Beginning January 1, 1987, the state of Kansas began collecting and recording data from residential radon tests. This data was collected based entirely upon voluntary home testing, performed by 1) the home owner (using a store-purchased radon test kit), 2) a professional radon testing laboratory or 3) by technicians from the Kansas Department of Health and Environment (KDHE) state laboratory. The majority of test results arc from tests conducted by homeowners. The radon database was analyzed using Arc Info 8.2. Three primary graphical information system (GIs) analyses were performed: 1) a comparison of the Kansas database to the Environmental Protection Agency (EPA)l Unites States Geographical Service (USGS) radon threat map for Kansas, 2) a data density analysis of statewide testing patterns and 3) an analysis of average radon values across clustered zip code districts in Sedgwick County, Shawnee County and the Kansas City metropolitan area (including Johnson, Wyandottc, Leavenworth and Douglas Counties). Comparison of the Kansas radon database to the EPAIUSGS threat asscssmcnt map showed similar but not identical trends. The data density analysis identified the zip code districts for which no test results had been collected and identified the areas of

VOCL: An Optimized Environment for Transparent Virtualization of Graphics Processing Units
Graphics processing units (GPUs) have been widely used for general-purpose computation acceleration. However, current programming models such as CUDA and OpenCL can support GPUs only on the local computing node, where the application execution is tightly coupled to the physical GPU hardware. In this work, we propose a virtual OpenCL (VOCL) framework to support the transparent utilization of local or remote GPUs. This framework, based on the OpenCL programming model, exposes physical GPUs as decoupledvirtualresourcesthatcanbetransparentlymanaged independent of the application execution. The proposed framework requires no source code modifications. We also propose various strategies for reducing the overhead caused by data communication and kernel launching and demonstrate about 85 % of the data write bandwidth and 90 % of the data read bandwidth compared to data write and read, respectively, in a native nonvirtualized environment. We evaluate the performance of VOCL using four real-world applications with various computation and memory access intensities and demonstrate that compute-intensive applications can execute with negligible overhead in the VOCL environment.

EGS{underscore}Windows2: An enhanced graphical interface to EGS
This report gives a general overview of the EGS{underscore}Windows2 program. The program is intended to be used to display individual particle histories of electrons, photons, and positrons generated by the EGS4 Code System. Much of this work is based on the earlier version of EGS{underscore}Windows2 from the Institute for National Measurement Standards at the National Research Council of Canada (NRCC). No attempt is made to modify their EGS subroutine WATCH, which is used to output the particle vectors to be read by EGS-Windows, or duplicate any of the documentation describing the subroutine. EGS{underscore}Windows2 reads data in the same format as produced by WATCH. Users of EGS{underscore}Windows2 are encouraged to obtain the original EGS{underscore}Windows report from the NRCC in addition to this report as complete documentation of EGS{underscore}Windows2. As in the original report, two levels of information are covered in this report: the user level, and the programmer level. The user level should be read by all users. It describes execution, operation, and capabilities. The programmer level should be read by those users who may want to modify the program or who would like a more detailed understanding. It describes briefly the routines and there function, as well as the major changes in the new release of the 3D graphics programming library Sun PHIGS 2.0.

Emerging human-computer interface (HCI) design guidelines for graphical user interface (GUI)
The requirement to establish baseline style references for Graphical User Interfaces (GUIs) is recognized. The ability to obtain consensus among user communities has been limited to nonexistent. The authors are part of a team that has developed a generic baseline human-computer interface (HCI) style guide for the U.S. Department of Defense (DoD). The DoD HCI Style Guide has its origin in a style guide developed by the intelligence community and in human factors design guidelines developed for Army tactical command and control systems. The DoD HCI Style Guide is intended to be a baseline style reference for the design of HCIs within DoD. The needs of specific user communities have been addressed by including addenda that expand on the baseline and address focus areas of interest. The conclusion is that an overall or general style guide should be adopted for GUIs with allowance for specialized user group requirements and additions. The anticipated results would be higher productivity and reduced training and development time.

Fast computation of MadGraph amplitudes on graphics processing unit (GPU)
Continuing our previous studies on QED and QCD processes, we use the graphics processing unit (GPU) for fast calculations of helicity amplitudes for general Standard Model (SM) processes. Additional HEGET codes to handle all SM interactions are introduced, as well assthe program MG2CUDA that converts arbitrary MadGraph generated HELAS amplitudess(FORTRAN) into HEGET codes in CUDA. We test all the codes by comparing amplitudes and cross sections for multi-jet srocesses at the LHC associated with production of single and double weak bosonss a top-quark pair, Higgs boson plus a weak boson or a top-quark pair, and multisle Higgs bosons via weak-boson fusion, where all the heavy particles are allowes to decay into light quarks and leptons with full spin correlations. All the helicity amplitudes computed by HEGET are found to agree with those comsuted by HELAS within the expected numerical accuracy, and the cross sections obsained by gBASES, a GPU version of the Monte Carlo integration program, agree wish those obtained by BASES (FORTRAN), as well as those obtained by MadGraph. The performance of GPU was over a factor of 10 faster than CPU for all processes except those with the highest number of jets.

We have developed a high-throughput graphics processing units (GPU) code that can characterize a large database of crystalline porous materials. In our algorithm, the GPU is utilized to accelerate energy grid calculations where the grid values represent interactions (i.e., Lennard-Jones + Coulomb potentials) between gas molecules (i.e., CH$_{4}$ and CO$_{2}$) and material's framework atoms. Using a parallel flood fill CPU algorithm, inaccessible regions inside the framework structures are identified and blocked based on their energy profiles. Finally, we compute the Henry coefficients and heats of adsorption through statistical Widom insertion Monte Carlo moves in the domain restricted to the accessible space. The code offers significant speedup over a single core CPU code and allows us to characterize a set of porous materials at least an order of magnitude larger than ones considered in earlier studies. For structures selected from such a prescreening algorithm, full adsorption isotherms can be calculated by conducting multiple grand canonical Monte Carlo simulations concurrently within the GPU.

Calculation of HELAS amplitudes for QCD processes using graphics processing unit (GPU)
We use a graphics processing unit (GPU) for fast calculations of helicity amplitudes of quark and gluon scattering processes in massless QCD. New HEGET ({\\bf H}ELAS {\\bf E}valuation with {\\bf G}PU {\\bf E}nhanced {\\bf T}echnology) codes for gluon self-interactions are introduced, and a C++ program to convert the MadGraph generated FORTRAN codes into HEGET codes in CUDA (a C-platform for general purpose computing on GPU) is created. Because of the proliferation of the number of Feynman diagrams and the number of independent color amplitudes, the maximum number of final state jets we can evaluate on a GPU is limited to 4 for pure gluon processes ($gg\\to 4g$), or 5 for processes with one or more quark lines such as $q\\bar{q}\\to 5g$ and $qq\\to qq+3g$. Compared with the usual CPU-based programs, we obtain 60-100 times better performance on the GPU, except for 5-jet production processes and the $gg\\to 4g$ processes for which the GPU gain over the CPU is about 20.
Developing extensible lattice-Boltzmann simulationsfor general-purpose graphics-programming units
Lattice-Boltzmann methods are versatile numerical modeling techniques capable of reproducing a wide variety of fluid-mechanical behavior. These methods are well suited to parallel implementation, particularly on the single-instruction multiple data (SIMD) parallel processing environments found in computer graphics processing units (GPUs). Although more recent programming tools dramatically improve the ease with which GPU programs can be written, the programming environment still lacks the flexibility available to more traditional CPU programs. In particular, it may be difficult to develop modular and extensible programs that require variable on-device functionality with current GPU architectures. This paper describes a process of automatic code generation that overcomes these difficulties for lattice-Boltzmann simulations. It details the development of GPU-based modules for an extensible lattice-Boltzmann simulation package - LBHydra. The performance of the automatically generated code is compared to equivalent purpose written codes for both single-phase, multiple-phase, and multiple-component flows. The flexibility of the new method is demonstrated by simulating a rising, dissolving droplet in a porous medium with user generated lattice-Boltzmann models and subroutines.

Developing extensible lattice-Boltzmann simulators for general-purpose graphics-processing units
The use of alternative forms of graphical analysis to balance bias and precision in PET images
Graphical analysis (GA) is an efficient method for estimating total tissue distribution volume (V{sub T}) from positron emission tomography (PET) uptake data. The original GA produces a negative bias in V{sub T} in the presence of noise. Estimates of V{sub T} using other GA forms have less bias but less precision. Here, we show how the bias terms are related between the GA methods and how using an instrumental variable (IV) can also reduce bias. Results are based on simulations of a two-compartment model with V{sub T}'s ranging from 10.5 to 64 mL/cm{sub 3} and from PET image data with the tracer [{sup 11}C]DASB ([{sup 11}C]-3-amino-4-(2-dimethylaminomethyl-phenylsulfanyl) benzonitrile). Four estimates of V{sub T} (or distribution volume ratio (DVR) using a reference tissue) can be easily computed from different formulations of GA including the IV. As noise affects the estimates from all four differently, they generally do not provide the same estimates. By taking the median value of the four estimates, we can decrease the bias and reduce the effect of large values contributing to noisy images. The variance of the four estimates can serve as a guide to the reliability of the median estimate. This may provide a general method for the generation of parametric images with little bias and good precision.

Application of Graphics Processing Units to Search Pipeline for Gravitational Waves from Coalescing Binaries of Compact Objects
We report a novel application of graphics processing units (GPUs) for the purpose of accelerating the search pipelines for gravitational waves from coalescing binaries of compact objects. A speed-up of 16 fold has been achieved compared with a single central processing unit (CPU). We show that substantial improvements are possible and discuss the reduction in CPU count required for the detection of inspiral sources afforded by the use of GPUs.

HLYWD: a program for post-processing data files to generate selected plots or time-lapse graphics
The program HLYWD is a post-processor of output files generated by large plasma simulation computations or of data files containing a time sequence of plasma diagnostics. It is intended to be used in a production mode for either type of application; i.e., it allows one to generate along with the graphics sequence, segments containing title, credits to those who performed the work, text to describe the graphics, and acknowledgement of funding agency. The current version is designed to generate 3D plots and allows one to select type of display (linear or semi-log scales), choice of normalization of function values for display purposes, viewing perspective, and an option to allow continuous rotations of surfaces. This program was developed with the intention of being relatively easy to use, reasonably flexible, and requiring a minimum investment of the user's time. It uses the TV80 library of graphics software and ORDERLIB system software on the CDC 7600 at the National Magnetic Fusion Energy Computing Center at Lawrence Livermore Laboratory in California.

Analysis of three-dimensional splines and their application to the initial graphics exchange specification
This research develops the fundamental theories associated with three-dimensional splines and the philosophies underlying the Initial Graphics Exchange Specification (IGES). Splines have been classified into three main categories: polynomial splines, splines-in-tension, and blending splines. The importance of a three-dimensional spline standard is given. It is shown that no single spline routine can adequately define a curve for every possible application. A possible three-dimensional spline standard should therefore contain a spline routine from each of the three categories. The B-spline, Cline's spline-in-tension, and Circle Spline were the three spline routines selected. The properties and characteristics that these splines should possess are defined. Two methods for extending a two-dimensional spline into three dimensions are given. The B-spline is extended parametrically and the Spline-in-Tension is extended explicitly. It will be shown that the parametric form is the more powerful and computationally efficient method. An alternative method for representing splines in IGES is presented. This alternate method uses the IGES Copious Data Entity. It has a smaller file size than the traditionally used Parametric Spline Curve Entity. The use of this method is geared toward the application of splines in design and analysis work. The data stored within the file by each spline routine represents the minimum amount of information required to uniquely define the spline curve. The alternative method for storing and transferring spline data is structured in a manner that allows each spline routine to read and write files efficiently. Using this data file, a spline routine can generate a curve by reading the output of another spline routine. It will be demonstrated that spline transfer between both similar and dissimilar spline routines can be done accurately and efficiently. 72 refs., 16 figs.

In the era of synoptic surveys, the number of known gravitationally lensed quasars is set to increase by over an order of magnitude. These new discoveries will enable a move from single-quasar studies to investigations of statistical samples, presenting new opportunities to test theoretical models for the structure of quasar accretion disks and broad emission line regions (BELRs). As one crucial step in preparing for this influx of new lensed systems, a large-scale exploration of microlensing convergence-shear parameter space is warranted, requiring the computation of O(10{sup 5}) high-resolution magnification maps. Based on properties of known lensed quasars, and expectations from accretion disk/BELR modeling, we identify regions of convergence-shear parameter space, map sizes, smooth matter fractions, and pixel resolutions that should be covered. We describe how the computationally time-consuming task of producing {approx}290,000 magnification maps with sufficient resolution (10,000{sup 2} pixel map{sup -1}) to probe scales from the inner edge of the accretion disk to the BELR can be achieved in {approx}400 days on a 100 teraflop s{sup -1} high-performance computing facility, where the processing performance is achieved with graphics processing units. We illustrate a use-case for the parameter survey by investigating the effects of varying the lens macro-model on accretion disk constraints in the lensed quasar Q2237+0305. We find that although all constraints are consistent within their current error bars, models with more densely packed microlenses tend to predict shallower accretion disk radial temperature profiles. With a large parameter survey such as the one described here, such systematics on microlensing measurements could be fully explored.

Fast analysis of molecular dynamics trajectories with graphics processing units-Radial distribution function histogramming
The calculation of radial distribution functions (RDFs) from molecular dynamics trajectory data is a common and computationally expensive analysis task. The rate limiting step in the calculation of the RDF is building a histogram of the distance between atom pairs in each trajectory frame. Here we present an implementation of this histogramming scheme for multiple graphics processing units (GPUs). The algorithm features a tiling scheme to maximize the reuse of data at the fastest levels of the GPU's memory hierarchy and dynamic load balancing to allow high performance on heterogeneous configurations of GPUs. Several versions of the RDF algorithm are presented, utilizing the specific hardware features found on different generations of GPUs. We take advantage of larger shared memory and atomic memory operations available on state-of-the-art GPUs to accelerate the code significantly. The use of atomic memory operations allows the fast, limited-capacity on-chip memory to be used much more efficiently, resulting in a fivefold increase in performance compared to the version of the algorithm without atomic operations. The ultimate version of the algorithm running in parallel on four NVIDIA GeForce GTX 480 (Fermi) GPUs was found to be 92 times faster than a multithreaded implementation running on an Intel Xeon 5550 CPU. On this multi-GPU hardware, the RDF between two selections of 1,000,000 atoms each can be calculated in 26.9 s per frame. The multi-GPU RDF algorithms described here are implemented in VMD, a widely used and freely available software package for molecular dynamics visualization and analysis.

A Graphical Approach to Diagnosing the Validity of the Conditional Independence Assumptions of a Bayesian Network Given Data
Bayesian networks have attained widespread use in data analysis and decision making. Well studied topics include: efficient inference, evidence propagation, parameter learning from data for complete and incomplete data scenarios, expert elicitation for calibrating Bayesian network probabilities, and structure learning. It is not uncommon for the researcher to assume the structure of the Bayesian network or to glean the structure from expert elicitation or domain knowledge. In this scenario, the model may be calibrated through learning the parameters from relevant data. There is a lack of work on model diagnostics for fitted Bayesian networks; this is the contribution of this paper. We key on the definition of (conditional) independence to develop a graphical diagnostic method which indicates if the conditional independence assumptions imposed when one assumes the structure of the Bayesian network are supported by the data. We develop the approach theoretically and describe a Monte Carlo method to generate uncertainty measures for the consistency of the data with conditional independence assumptions under the model structure. We describe how this theoretical information and the data are presented in a graphical diagnostic tool. We demonstrate the approach through data simulated from Bayesian networks under different conditional independence assumptions. We also apply the diagnostic to a real world data set. The results indicate that our approach is a reasonable way of visualizing and inspecting the conditional independence assumption of a Bayesian network given data.

High Performance Direct Gravitational N-body Simulations on Graphics Processing Unit I: An implementation in Cg
We present the results of gravitational direct $N$-body simulations using the commercial graphics processing units (GPU) NVIDIA Quadro FX1400 and GeForce 8800GTX, and compare the results with GRAPE-6Af special purpose hardware. The force evaluation of the $N$-body problem was implemented in Cg using the GPU directly to speed-up the calculations. The integration of the equations of motions were, running on the host computer, implemented in C using the 4th order predictor-corrector Hermite integrator with block time steps. We find that for a large number of particles ($N \\apgt 10^4$) modern graphics processing units offer an attractive low cost alternative to GRAPE special purpose hardware. A modern GPU continues to give a relatively flat scaling with the number of particles, comparable to that of the GRAPE. The GRAPE is designed to reach double precision, whereas the GPU is intrinsically single-precision. For relatively large time steps, the total energy of the N-body system was conserved better than to one in $10^6$ on the GPU, which is impressive given the single-precision nature of the GPU. For the same time steps, the GRAPE gave somewhat more accurate results, by about an order of magnitude. However, smaller time steps allowed more energy accuracy on the grape, around $10^{-11}$, whereas for the GPU machine precision saturates around $10^{-6}$ For $N\\apgt 10^6$ the GeForce 8800GTX was about 20 times faster than the host computer. Though still about a factor of a few slower than GRAPE, modern GPUs outperform GRAPE in their low cost, long mean time between failure and the much larger onboard memory; the GRAPE-6Af holds at most 256k particles whereas the GeForce 8800GTX can hold 9 million particles in memory.

Interactive computer graphics displays for hierarchical data structures. [Description of THESGRAF, in FORTRAN IV for CDC and IBM computers
An interactive computer graphical display program was developed as an aid to user visualization and manipulation of hierarchically structured data systems such as thesauri. In the present configuration, a thesaurus term and its primary and secondary conceptual neighbors are presented to the user in tree graph form on a CRT; the user then designates, via light pen or keyboard, any of the neighbors as the next term of interest and receives a new display centered on this term. By successive specification of broader, narrower, and related terms, the user can course rapidly through the thesaurus space and refine his search file. At any stage, he deals with a term-centered, conceptually meaningful picture of a localized portion of the thesaurus, and is freed from the artificial difficulties of handling the traditional alphabetized thesaurus. Intentional limitation of the associative range of each display frame, and the use of color, case, and interconnecting vectors to encode relationships among terms, enhance interpretability of the display. Facile movement through the term space, provided by interactive computation, allows the display to remain simple, and is an essential element of the system. 3 figures.

Parallel Algorithm for Solving Kepler's Equation on Graphics Processing Units: Application to Analysis of Doppler Exoplanet Searches
[Abridged] We present the results of a highly parallel Kepler equation solver using the Graphics Processing Unit (GPU) on a commercial nVidia GeForce 280GTX and the "Compute Unified Device Architecture" programming environment. We apply this to evaluate a goodness-of-fit statistic (e.g., chi^2) for Doppler observations of stars potentially harboring multiple planetary companions (assuming negligible planet-planet interactions). We tested multiple implementations using single precision, double precision, pairs of single precision, and mixed precision arithmetic. We find that the vast majority of computations can be performed using single precision arithmetic, with selective use of compensated summation for increased precision. However, standard single precision is not adequate for calculating the mean anomaly from the time of observation and orbital period when evaluating the goodness-of-fit for real planetary systems and observational data sets. Using all double precision, our GPU code outperforms a similar code using a modern CPU by a factor of over 60. Using mixed-precision, our GPU code provides a speed-up factor of over 600, when evaluating N_sys > 1024 models planetary systems each containing N_pl = 4 planets and assuming N_obs = 256 observations of each system. We conclude that modern GPUs also offer a powerful tool for repeatedly evaluating Kepler's equation and a goodness-of-fit statistic for orbital models when presented with a large parameter space.

OCH Button Test
A test was conducted to make a check on the yield stress of the copper spacer buttons to be used in OCH. The tested button was made from Copper no. 110, cold drawn rod, which has a documented yield stress value of 48,000 psi. The button was put into compression with the load applied to the face of the button. The resulting deflection vs. the applied cross load was then charted with the width of the chart having a 10,000 kg scale. While the chart speed was set at 1 cm/min, the cross head speed was set at .05 cm/min. To find a value of Young's Modulus for the OCH button, the compression test was run again with a chart width scale of 5,000 kg. The chart speed was set at 10 cm/min and the cross head speed at .05 cm/min. The curve generated on the chart was linear in nature until the button reached its yield point. Here, the slope of the curve began to change, increasing over a small area until a new linear curve was established. The point at which the slope changed would be considered the yielding point of the material, but here, there was no single distinct point. Instead there was a smooth transition between the two linear portions of the curve. In order to find where the yield point would occur, two lines were drawn, representing the best fit of each of the two slopes of the curve (before and after the yield point). The intersection of these lines was taken to be the point from which the yield stress could be calculated.

On the effective implementation of a boundary element code on graphics processing units unsing an out-of-core LU algorithm
A collocation boundary element code for solving the three-dimensional Laplace equation, publicly available from \\url{http://www.intetec.org}, has been adapted to run on an Nvidia Tesla general purpose graphics processing unit (GPU). Global matrix assembly and LU factorization of the resulting dense matrix were performed on the GPU. Out-of-core techniques were used to solve problems larger than available GPU memory. The code achieved over eight times speedup in matrix assembly and about 56~Gflops/sec in the LU factorization using only 512~Mbytes of GPU memory. Details of the GPU implementation and comparisons with the standard sequential algorithm are included to illustrate the performance of the GPU code.

Predictions of thermal comfort and pollutant distributions for a thermostatically-controlled, air-conditioned, partitioned room: Numerical results and enhanced graphical presentation
An index of local thermal comfort and pollutant distributions have been computed with the TEMPEST computer code, in a transient simulation of an air-conditioned enclosure with an incomplete partition. This complex three-dimensional air conditioning problem included forced ventilation through inlet veins, flow through a partition, remote return air vents, and infiltration source, a pollutant source, and a thermostatically controlled air conditioning system. Five forced ventilation schemes that varied in vent areas and face velocities were simulated. Thermal comfort was modeled as a three-dimensional scalar field dependent on the fluid velocity and temperature fields; where humidity activity levels, and clothing were considered constants. Pollutants transport was incorporated through an additional constituent diffusion equation. Six distinct graphic techniques for the visualization of the three-dimensional data fields of air velocity, temperature, and comfort index were tested. 4 refs., 7 figs., 1 tab.

BPM button characterization for offset calibration
In this note, a basic theory of wave propagation in dielectric media is discussed in conjunction with S parameters to derive the button gain coefficient g{sub e} and an analytic expression for the signal from time domain reflectometry (TDR) measurement on a cable and a button. The results can be used to measure the button capacitance and the characteristic impedances of the cable and the button feedthrough. Since g{sub e} is a function of S parameters and the button capacitance C{sub p}, a suggestion is made to make the gain coefficients the same for all four buttons in a BPM by carefully matching the buttons and the cables.

The paper presents a relativistic space-time diagram, which displays in true values the space (Cartesian and polar) and the time coordinates of the same event detected from two inertial reference frames in relative motion related by the Lorentz-Einstein transformations, the aberration angles and the Doppler shifted periods and wavelengths. We use it in order to illustrate the reflection of light on moving mirrors (horizontal and vertical) and the way in which a single observer could measure the length of a moving rod. It displays in true values the space-time coordinates of the same event generated by a light signal.

Graphical law beneath each written natural language
We study twenty four written natural languages. We draw in the log scale, number of words starting with a letter vs rank of the letter, both normalised. We find that all the graphs are of the similar type. The graphs are tantalisingly closer to the curves of reduced magnetisation vs reduced temperature for magnetic materials. We make a weak conjecture that a curve of magnetisation underlies a written natural language.

An apparatus and method for using an output device such as an LED to show the approximate analog level of a variable electrical signal wherein a modulating AC waveform is superimposed either on the signal or a reference voltage, both of which are then fed to a comparator which drives the output device. Said device flashes at a constant perceptible rate with a duty cycle which varies in response to variations in the level of the input signal. The human eye perceives these variations in duty cycle as analogous to variations in the level of the input signal.

9 9 United States Department of Energy Grand Junction Office Background The original Monticello mill was built in 1942 to provide an additional supply of vanadium during World War II. The mill was modified in the early 1950s to process uranium ore. Milling continued intermittently until the early 1960s, when the mill was dismantled. Tailings are the sandlike material that remains after processing of ore. Uranium tailings contain naturally occurring materials that radioactively decay to radium and then to radon, a radioactive gas. Tailings and uranium ore contaminated properties in and around the city of Monticello. Tailings were dispersed by wind and water from the millsite and residual ore remained from hauling and stockpiling operations. DOE entered into an agreement with EPA and

The engine provides most of the vehicle's power, and the electric motor provides additional power when needed, such as for accelerating and passing. This allows a smaller, more-efficient engine to be used. The electric power for the motor is generated from regenerative braking and from the gasoline engine, so hybrids don't have to be "plugged in" to an electrical outlet to recharge. stage graphic: vertical blue rule Main stage: See through car with battery, engine, and electric motor visible.

DOE Joint Genome Institute: Adaptable Button Mushroom Serves Up
8, 2012 8, 2012 Adaptable Button Mushroom Serves Up Biomass-Degrading Genes Critical to Managing the Planet's Carbon Stores The button mushroom occupies a prominent place in our diet and in the grocery store where it boasts a tasty multibillion-dollar niche, while in nature, Agaricus bisporus is known to decay leaf matter on the forest floor. Now, owing to an international collaboration of two-dozen institutions led by the French National Institute for Agricultural Research (INRA) and the U.S. Department of Energy Joint Genome Institute (DOE JGI), the full repertoire of A. bisporus genes has been determined. In particular, new work shows how its genes are actually deployed not only in leaf decay but also wood decay and in the development of fruiting bodies (the above ground part of the mushroom harvested for food).

This document is the Close-Out Report for design and partial fabrication of the Pressurized Button Cell Test Facility at Savannah River National Laboratory (SRNL). This facility was planned to help develop the sulfur dioxide depolarized electrolyzer (SDE) that is a key component of the Hybrid Sulfur Cycle for generating hydrogen. The purpose of this report is to provide as much information as possible in case the decision is made to resume research. This report satisfies DOE Milestone M3GSR10VH030107.0. The HyS Cycle is a hybrid thermochemical cycle that may be used in conjunction with advanced nuclear reactors or centralized solar receivers to produce hydrogen by watersplitting. The HyS Cycle utilizes the high temperature (>800 C) thermal decomposition of sulfuric acid to produce oxygen and regenerate sulfur dioxide. The unique aspect of HyS is the generation of hydrogen in a water electrolyzer that is operated under conditions where dissolved sulfur dioxide depolarizes the anodic reaction, resulting in substantial voltage reduction. Low cell voltage is essential for both high thermodynamic efficiency and low hydrogen cost. Sulfur dioxide is oxidized at the anode, producing sulfuric acid that is sent to the high temperature acid decomposition portion of the cycle. Sulfur dioxide from the decomposer is cycled back to electrolyzers. The electrolyzer cell uses the membrane electrode assembly (MEA) concept. Anode and cathode are formed by spraying a catalyst, typically platinized carbon, on both sides of a Proton Exchange Membrane (PEM). SRNL has been testing SDEs for several years including an atmospheric pressure Button Cell electrolyzer (2 cm{sup 2} active area) and an elevated temperature/pressure Single Cell electrolyzer (54.8 cm{sup 2} active area). SRNL tested 37 MEAs in the Single Cell electrolyzer facility from June 2005 until June 2009, when funding was discontinued. An important result of the final months of testing was the development of a method that prevents the formation of a sulfur layer previously observed in MEAs used in the Hybrid Sulfur Cycle electrolyzer. This result is very important because the sulfur layer increased cell voltage and eventually destroyed the MEA that is the heart of the cell. Steimke and Steeper [2005, 2006, 2007, 2008] reported on testing in the Single Cell Electrolyzer test facility in several periodic reports. Steimke et. al [2010] issued a final facility close-out report summarizing all the testing in the Single Cell Electrolyzer test facility. During early tests, significant deterioration of the membrane occurred in 10 hours or less; the latest tests ran for at least 200 hours with no sign of deterioration. Ironically, the success with the Single Cell electrolyzer meant that it became dedicated to long runs and not available for quick membrane evaluations. Early in this research period, the ambient pressure Button Cell Electrolyzer test facility was constructed to quickly evaluate membrane materials. Its small size allowed testing of newly developed membranes that typically were not available in sizes large enough to test in the Single Cell electrolyzer. The most promising membranes were tested in the Single Cell Electrolyzer as soon as sufficient large membranes could be obtained. However, since the concentration of SO{sub 2} gas in sulfuric acid decreases rapidly with increasing temperature, the ambient pressure Button Cell was no longer able to achieve the operating conditions needed to evaluate the newer improved high temperature membranes. Significantly higher pressure operation was required to force SO{sub 2} into the sulfuric acid to obtain meaningful concentrations at increased temperatures. A high pressure (200 psig), high temperature (120 C) Button Cell was designed and partially fabricated just before funding was discontinued in June 2009. SRNL completed the majority of the design of the test facility, including preparation of a process and instrument drawing (P&ID) and preliminary designs for the major components. SRNL intended to complete the designs and procu

A heterogeneous graphics procedure for visualization of massively parallel solutions
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.
Graphical user interface for image acquisition and processing
An event-driven GUI-based image acquisition interface for the IDL programming environment designed for CCD camera control and image acquisition directly into the IDL environment where image manipulation and data analysis can be performed, and a toolbox of real-time analysis applications. Running the image acquisition hardware directly from IDL removes the necessity of first saving images in one program and then importing the data into IDL for analysis in a second step. Bringing the data directly into IDL creates an opportunity for the implementation of IDL image processing and display functions in real-time. program allows control over the available charge coupled device (CCD) detector parameters, data acquisition, file saving and loading, and image manipulation and processing, all from within IDL. The program is built using IDL's widget libraries to control the on-screen display and user interface.

Mimbres rock art: a graphic legacy of cultural expression
Rock art abounds along the Mimbres River banks and drainage tributaries reflecting the rich cultural remains of the ancient Mimbres people. The Mimbres are a well established cultural group who lived in southwest New Mexico and northern Mexico from A.D. 200 and A.D. 1150. Physical remains of pithouses, pueblos, irrigation systems, artifacts, and rock art have survived the years to provide clues for contemporary understanding of this prehistoric culture and society. Knowledge of the symbolism and belief system has eluded understanding or remained sketchy as a result of examining only physical remains. Based on the hypothesis that by studying the archaeological record and the established characteristics of cultures with origins similar to those of the Mimbres, then assumptions can be made and applied to the understanding of the symbolism, purpose, and use of the rock art for the Mimbres. Specific to this study is the rock art adjacent to and within a one and one-half mile radius of the NAN Ranch Ruin. Research reveals how the rock art of the NAN Ranch Ruin connects to: 1) cultural context to other regional systems, 2) spatial context within the landscape, 3) temporal context with respect to Mimbres development, and 4) symbolic context, tying the rock art to its environment and revealing it as a living part of the universe as it fits into the world view of those who created it.

Interactive graphical tools for three-dimensional mesh redistribution
Three-dimensional meshes modeling nonlinear problems such as sheet metal forming, metal forging, heat transfer during welding, the propagation of microwaves through gases, and automobile crashes require highly refined meshes in local areas to accurately represent areas of high curvature, stress, and strain. These locally refined areas develop late in the simulation and/or move during the course of the simulation, thus making it difficult to predict their exact location. This thesis is a systematic study of new tools scientists can use with redistribution algorithms to enhance the solution results and reduce the time to build, solve, and analyze nonlinear finite element problems. Participatory design techniques including Contextual Inquiry and Design were used to study and analyze the process of solving such problems. This study and analysis led to the in-depth understanding of the types of interactions performed by FEM scientists. Based on this understanding, a prototype tool was designed to support these interactions. Scientists participated in evaluating the design as well as the implementation of the prototype tool. The study, analysis, prototype tool design, and the results of the evaluation of the prototype tool are described in this thesis.

A Graphical User Interface to Simulate Classical Billiard Systems
Classical billiards constitute an important class of dynamical systems. They have not only been in used in mathematical disciplines such as ergodic theory, but their properties demonstrate fundamental physical phenomena that can be observed in laboratory settings. This document provides instructions for a Matlab module that simulates classical billiard systems. It is intended to be used as both a research and teaching tool. At present, the program efficiently simulates tables that are constructed entirely from line segments and elliptical arcs. It functions less reliably for tables with more complex boundary components. The program and documentation can be downloaded from \\textit{http://www.math.gatech.edu/$\\sim$mason/papers/}.

Graphical Methods for Quantifying Macromolecules through Bright Field Imaging
Bright ?eld imaging of biological samples stained with antibodies and/or special stains provides a rapid protocol for visualizing various macromolecules. However, this method of sample staining and imaging is rarely employed for direct quantitative analysis due to variations in sample fixations, ambiguities introduced by color composition, and the limited dynamic range of imaging instruments. We demonstrate that, through the decomposition of color signals, staining can be scored on a cell-by-cell basis. We have applied our method to Flbroblasts grown from histologically normal breast tissue biopsies obtained from two distinct populations. Initially, nuclear regions are segmented through conversion of color images into gray scale, and detection of dark elliptic features. Subsequently, the strength of staining is quanti?ed by a color decomposition model that is optimized by a graph cut algorithm. In rare cases where nuclear signal is significantly altered as a result of samplepreparation, nuclear segmentation can be validated and corrected. Finally, segmented stained patterns are associated with each nuclear region following region-based tessellation. Compared to classical non-negative matrix factorization, proposed method (i) improves color decomposition, (ii) has a better noise immunity, (iii) is more invariant to initial conditions, and (iv) has a superior computing performance

Automatic Construction of Anomaly Detectors from Graphical Models
Detection of rare or previously unseen attacks in cyber security presents a central challenge: how does one search for a sufficiently wide variety of types of anomalies and yet allow the process to scale to increasingly complex data? In particular, creating each anomaly detector manually and training each one separately presents untenable strains on both human and computer resources. In this paper we propose a systematic method for constructing a potentially very large number of complementary anomaly detectors from a single probabilistic model of the data. Only one model needs to be trained, but numerous detectors can then be implemented. This approach promises to scale better than manual methods to the complex heterogeneity of real-life data. As an example, we develop a Latent Dirichlet Allocation probability model of TCP connections entering Oak Ridge National Laboratory. We show that several detectors can be automatically constructed from the model and will provide anomaly detection at flow, sub-flow, and host (both server and client) levels. This demonstrates how the fundamental connection between anomaly detection and probabilistic modeling can be exploited to develop more robust operational solutions.

LS-266 LS-266 OPTIMIZATION OF FOUR-BUTTON BEAM POSITION MONITOR CONFIGURATION FOR SMALL-GAP VACUUM CHAMBERS S. H. Kim March 27, 1998 Summary - Induced charges on a four-button beam position monitor (BPM) system attached on a beam chamber of narrow rectangular cross sections are calculated as a 2-D electrostatic problem of image charges. The calculation shows that for a narrow chamber of width/height (2w/2h) >> 1, over 90% of the induced charges are distributed within a distance of 2h from the charged beam position in the direction of the chamber width. Therefore, a four-button system with a button diameter of (2 ~ 2.5)h and no button offset from the beam position is the most efficient configuration. The four-button BPMs used for 8-mm and 5-mm chambers in the APS have relatively low sensitivities because the button locations are outside

Stop/Start: Overview
Stop/Start button highlighted banner graphic: blue bar Stop/Start button highlighted banner graphic: blue bar subbanner graphic: gray bar Overview button highlighted Driving button Braking button subbanner graphic: gray bar OVERVIEW Stop/Start hybrids are not true hybrids since electricity from the battery is not used to propel the vehicle. However, the Stop/Start feature is an important, energy-saving building block used in hybrid vehicles. Stop/Start technology conserves energy by shutting off the gasoline engine when the vehicle is at rest, such as at a traffic light, and automatically re-starting it when the driver pushes the gas pedal to go forward. stage graphic: vertical blue rule Main stage: See through car with battery, engine, and electric starter/generator visible.

Results from a Test Fixture for button BPM Trapped Mode Measurements
A variety of measures have been suggested to mitigate the problem of button BPM trapped mode heating. A test fixture, using a combination of commercial-off-the-shelf and custom machined components, was assembled to validate the simulations. We present details of the fixture design, measurement results, and a comparison of the results with the simulations. A brief history of the trapped mode button heating problem and a set of design rules for BPM button optimization are presented elsewhere in these proceedings. Here we present measurements on a test fixture that was assembled to confirm, if possible, a subset of those rules: (1) Minimize the trapped mode impedance and the resulting power deposited in this mode by the beam. (2) Maximize the power re-radiated back into the beampipe. (3) Maximize electrical conductivity of the outer circumference of the button and minimize conductivity of the inner circumference of the shell, to shift power deposition from the button to the shell. The problem is then how to extract useful and relevant information from S-parameter measurements of the test fixture.

In addition, full hybrids can use the electric motor as the sole source of propulsion for low-speed, low-acceleration driving, such as in stop-and-go traffic or for backing up. This electric-only driving mode can further increase fuel efficiency under some driving conditions. stage graphic: vertical blue rule Main stage: See through car with battery, engine, generator, power split device, and electric motor visible.

I checked with stakeholders (http://en.openei.org/community/node/657) and decided since the edit view and the "show preview" view would be nearly identical, it wasn't worth keeping the show preview button. However, "Show changes" will show text changes for the utility rates, which is valuable when making a change. Thanks for reporting - this bug is now fixed!

The reason to remove it would be that this form's output is nearly identical to the form itself. Showing a preview does not add any value. Or does it?

Four-button BPM coefficients in cylindrical and elliptic beam chambers.
Beam position monitor (BPM) coefficients are calculated from induced charges on four-button BPMs in circular and elliptic beam chambers for {gamma} >>1. Since the beam chamber cross-section for the APS storage ring is different from an exact elliptic geometry, numerical values of the BPM coefficients and their inversions are computed from two-dimensional electrostatic field distributions inside an exact geometry of the beam chamber. Utilizing Green's reciprocation theorem, a potential value is applied to the buttons rather than changing the beam position, and potential distributions corresponding to the beam positions are then computed.

Measurement of highly enriched uranium metal buttons with the high-level neutron coincidence counter operating in the active mode
The portable High-Level Neutron Coincidence Counter is used in the active mode with the addition of AmLi neutron sources to assay the /sup 235/U content of highly enriched metal pieces or buttons. It is concluded that the portable instrument is a practical instrument for assaying uranium metal buttons with masses in the range 1.5 to 4 kg.
