Exploring Materials at Virginia Tech
(Materials Science and Engineering, 2001)
Using Interactive Maps in Community Applications
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2001), TR-01-07
Interactive maps provide unique ways to support community applications. In particular, they enable new collaborative activities. Map-based navigation supports a community environment as well as virtual tours. Interactive ...
Empirical Comparisons of Virtual Environment Displays
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2001), TR-01-19
There are many different visual display devices used in virtual environment (VE) systems. These displays vary along many dimensions, such as resolution, field of view, level of immersion, quality of stereo, and so on. In ...
Programming Environments for Multidisciplinary Grid Communities
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2001-07-01), TR-01-14
Rapid advances in technological infrastructure as well as the emphasis on application support systems have signaled the maturity of grid computing. Today’s grid computing environments (GCEs) extend the notion of a programming ...
Using Pinch Gloves(TM) for both Natural and Abstract Interaction Techniques in Virtual Environments
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2001), TR-01-23
Usable three-dimensional (3D) interaction techniques are difficult to design, implement, and evaluate. One reason for this is a poor understanding of the advantages and disadvantages of the wide range of 3D input devices, ...
Genetic spot optimization for peak power estimation in large VLSI circuits
(Hindawi Publishing Corporation, 2001-07-10)
Estimating peak power involves optimization of the circuit's switching function. The switching of a given gate is not only dependent on the output capacitance of the node, but also heavily dependent on the gate delays in ...
Opening Remarks and Historical Overview Part B
This presentation introduces the Open Archives Initiative (OAI) and discusses OAI tools such as the RE Automatic Test Suite, RE Browsing, and ARC.
Open Archiving @ Virginia Tech
This presentation discusses why Virginia Tech is involved in the Open Archives Initiative (OAI), as well as OAI compliance, OAI technical requirements, and more.
Scalability Analysis of Parallel GMRES Implementations
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2001), TR-01-06
Applications involving large sparse nonsymmetric linear systems encourage parallel implementations of robust iterative solution methods, such as GMRES(k). Two parallel versions of GMRES(k) based on different data distributions ...
Usability Evaluation in Virtual Environments: Classification and Comparison of Methods
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2001), TR-01-17
Virtual environments (VEs) are a relatively new type of human-computer interface in which users perceive and act in a three-dimensional world. The designers of such systems cannot rely solely on design guidelines for ...
