We describe our implementation of several e cient parallel algorithms on the massively parallel SIMD machine MasPar MP-1 with virtual processing. The MPL language that we used on the MasPar MP-1 does not support virtual processing. In this paper, we describe the implementation of virtual processing for several combinatorial algorithms using the MPL language. We present our data allocation schem...

Initial applications of the GriPhyN Chimera Virtual Data System have been performed within the context of CMS Production of Monte Carlo Simulated Data. The GriPhyN Chimera system consists of four primary components: 1) a Virtual Data Language, which is used to describe virtual data products, 2) a Virtual Data Catalog, which is used to store virtual data entries, 3) an Abstract Planner, which re...

Virtual Reality Modelling Language (VRML) is description language, which belongs to a field Window on World virtual reality system. The file, which is in VRML format, can be interpreted by VRML explorer in three-dimensional scene. VRML was created with aim to represent virtual reality on Internet easier. Development of 3D graphic is connected with Silicon Graphic Corporation. VRML 2.0 is the fi...

The applications of 3D virtual environments and voice user interface (VUI) on personal computers has received significant attentions in recent years. Since speech is the most natural way of communication, incorporating VUI into virtual environments can greatly enhance user interaction and immersiveness. Although there have been many researches addressing the issue of integrating VUI and 3D virt...

The ever-increasing need for flexibility of business collaborations that ultimately involve a large number of virtual enterprises puts demands on their design. Competitive markets require the collaborations to be highly agile, effective, and efficient. This paper defines Internet scale virtual enterprise collaborations (ISVECs) as well as their characteristics. We further present a process mode...
