Modern web-based Scientific Visualization applications try to overcome common limitations imposed by limited internet bandwidth, server bottlenecks or network latency. A further aspect is the desire to gain platform independence by solely using instruments which are platform independent by conception: the programming language Java, the Virtual Reality modeling Language (VRML), or the 3D API *** present a prototype of a hybrid web-based Scientific Visualization system which makes use of the increasing computational power of modern desktop workstations and personal computers on the client side, and the superior performance provided by a powerful machine on the server side. In order to achieve high interaction rates and to balance computational load the user can dynamically assign selected tasks to his client or to the *** the scientific field of human modeling we have implemented a hybrid web-based toolkit for the modeling of human muscles and skin. Our application allows the on-line generation and manipulation of three-dimensional implicit muscle models in a heterogeneous network and it offers various parameters to adjust computation and response time versus rendering quality.

Linking anatomy and physiology in modeling respiratory mechanics

Studies in Health Technology and Informatics 1996年 29卷 580-589页

作者： Kaye, J. Metaxas, D. Badler, N. Clarke, J. Webber, B. Center for Human Modeling and Simulation Department of Computer and Information Science University of Pennsylvania Philadelphia PA 19104-6389 United States

We present an integrated 3D virtual environment for the quantitative modeling of the anatomy and the physiology of the pulmonary system. Our approach formally integrates 3D deformable object modeling with conventional models of respiratory mechanics. We demonstrate quantitatively, aspects of the behavior of the respiratory system qualitatively known to clinicians, such as normal quiet breathing and an open sucking chest wound. Our methodology is general and can be used to model both the anatomy and the physiology at many levels of detail. Another important aspect of our approach is that based on our previously developed computer vision techniques we can make such a simulation patient specific. The usefuleness of such a system is manifold. Medical education, surgical planning, disease diagnosis are some of the many areas such a system can be applied. © The authors 1996.

The objectives of Human Engineering (HE) are generally viewed as increasing human performance, reducing human error, enhancing personnel and equipment safety, and reducing training and related personnel costs. There are other benefits that are thoroughly consistent with the direction of the Navy of the future, chief among these is reduction of required numbers of personnel to operate and maintain Navy ships. The Naval Research Advisory Committee (NRAC) report on Man-Machine Technology in the Navy estimated that one of the benefits from increased application of man-machine technology to Navy ship design is personnel reduction as well as improving system availability, effectiveness, and safety The objective of this paper is to discuss aspects of the human engineering design of ships and systems that affect manning requirements, and impact human-performance and safety The paper will also discuss how the application of human engineering leads to improved performance, and crew safety, and reduced workload, all of which influence manning levels. Finally, the paper presents a discussion of tools and case studies of good human engineering design practices which reduce manning.

TACTICAL ROUTE PLANNING: NEW ALGORITHMS FOR DECOMPOSING THE MAP

International Journal on Artificial Intelligence Tools 1996年第1N02期5卷 199-218页

This paper defines a new approach and investigates a fundamental problem in route planners. This capability is important for robotic vehicles(Martian Rovers, etc.) and for planning off-road military maneuvers. The emphasis throughout this paper will be on the design and analysis and hieiaichical implementation of our route planner. This work was motivated by anticipation of the need to search a grid of a trillion points for optimum routes. This cannot be done simply by scaling upward from the algorithms used to search a grid of 10,000 points. Algorithms sufficient for the small grid are totally inadequate for the large grid. Soon, the challenge will be to compute off-road routes more than 100 km long and with a one or two-meter grid. Previous efforts are reviewed and the data structures, decomposition methods and search algorithms are analyzed and limitations are discussed. A detailed discussion of a hieraichical implementation is provided and the experimental results are analyzed.

Redundancy in model representation: a blessing or a curse?

With the intent of dispelling the prevailing negative connotations associated with redundancy, we argue that redundancy can effect benefits in model specification as opposed to model execution. Sources of redundancy are classified as accidental or intentional, and several examples are given for each. The comparative benefits and detriments are discussed briefly, and for the most interesting source of redundancy that induced by a modeling methodology, we demonstrate that automated elimination of redundancy can actually improve the execution time. Although the set of models investigated is small, these results are encouraging for researchers in modeling methodologies using automated model diagnosis.

Native and generic parallel programming environments on a transputer and a PowerPC platform

引用

Concurrency and Computation: Practice and Experience 1996年第1期8卷

作者： A.G. Hoekstra P.M.A. Sloot F. van der Linden M. van Muiswinkel J.J.J. Vesseur L.O. Hertzberger Parallel Scientific Computing & Simulation Group Computer Systems Department Faculty of Mathematics and Computer Science University of Amsterdam Kruislaan 409 1098 SJ Amsterdam The Netherlands

Genericity of parallel programming environments, enabling development of portable parallel programs, is expected to result in performance penalties. Furthermore, programmability and tool support of programming environments are important issues if a choice between programming environments has to be made. In this paper we propose a methodology to compare native and generic parallel programming environments, taking into account such competing issues as portability and performance. As a case study, this paper compares the Iserver-Occam, Parix, Express and PVM parallel programming environments on a 512-node Parasytec GCel. Furthermore, we apply our methodology to compare Parix and PVM on a new architecture, a 32-node Parsytec PowerXplorer, which is based on the PowerPC chip. In our approach we start with a representative application and isolate the basic (environment)-dependent building blocks. These basic building blocks, which depend on floating-point performance and communication capabilities of the environments, are analysed independently. We have measured point-to-point communication times, global communication times and floating-point performance. All information is combined into a time complexity analysis, allowing comparison of the environments on different degrees of functionality. Together with demands for portability of the code and development time (i.e. programmability), an overall judgement of the environments is given.

The MediSim system extends virtual environments (both local and network) to represent simulated medical personnel interacting with simulated casualties. Our technology fosters dual-use applications involving planning, training, and evaluation of both medical corpsmen and civilian EMTs. Behaviors and behavioral control are being developed for the medical corpsmen that will enable their actions on the digital battlefield to conform to both military practice and medical protocols. From situationally-appropriate injury models, a set of physical and behavioral manifestations in a simulated casualty will be determined and portrayed on a three-dimensional body.

FUTURE GENERATION computer SYSTEMS 1994年第2-3期10卷 305-308页

作者： DERONDE, JF SLOOT, PMA BEEMSTER, M HERTZBERGER, LO Parallel Scientific Computing and Simulation Group Department of Computer Science - University of Amsterdam Kruislaan 403 1098 SJ Amsterdam The Netherlands

A simulation methodology for predicting the performance of sequential programs as well as data parallel (SPMD) programs on parallel and distributed platforms is presented. The proposed methodology comprises a parameterised description of the applications as well as the target machines. An integrated simulation procedure estimates the time complexity of the (SPMD) application given a well-defined hardware platform and predicts the execution behaviour. The methodology has been actualised in terms of a toolset currently under development at the University of Amsterdam.
