The next evolutionary step in enhancing video communication fidelity over wired and wireless networks is taken by adding scene dep.h. Three-dimensional video using integral imaging (II) based capture and display subsystems has shown promising results and is now in the early prototype stage. We have created a ray-tracing based interactive simulation environment to generate II video sequences as a way to assist in the development, evaluation and quick adoption of these new emerging techniques into the whole communication chain. A generic II description model is also proposed as the base for the simulation environment. This description model facilitate optically accurate II rendering using MegaPOV, a customized version of the open-source ray tracing package POV-Ray. By using MegaPOV as a rendering engine the simulation environment fully incorporate the scene description language of POV-Ray to exactly define a virtual scene. Generation and comparability of II video sequences adhering to different II-techniques is thereby greatly assisted, compared to experimental research. The initial development of the simulation environment is focused on generating and visualizing II source material adhering to the optical properties of different II-techniques published in the literature. Both temporally static as well as dynamic systems are considered. The simulation environment's potential for easy dep.oyment of integral imaging video sequences adhering to different II-techniques is demonstrated.

Supply chains are distributed manufacturing systems composed of various resources belonging to different companies. The configuration of the supply chain network, integrated with Internet and web-based electronic market places, is essential for business to pursue a competitive advantage. This paper develops a model describing the integrated e-supply chain network and formulates a multi-criteria integer linear optimization problem to select the candidates and the links connecting the stages of the e-supply chain. Hence, some multi-criteria objective functions are defined and suited constraints are introduced on the basis of the digraph modelling the supply chain network. The proposed methodology is illustrated by way of a case study describing a network for desktop computer production.

Grid services provide an important abstract layer on top of heterogeneous components (hardware and software) that take part into a Grid environment. In this scenario, applications, like scientific visualization, require access to data of non-conventional data types, like fluid path geometry, and the evaluation of special user programs on these data. In order to support such applications we are developing CoDIMS-G, which is a data and program integration service for the Grid. CoDIMS-G provides users transparent access to data and programs distributed on the Grid, as well as dynamic resource allocation and management. We conceived a new node scheduling algorithm and designed an adaptive distributed query engine for the grid environment. Copyright 2004 ACM.

A loop with irregular assignment computations contains loop-carried output data dep.ndences that can only be detected at run-time. In this paper, a load-balanced method based on the inspector-executor model is proposed to parallelize this loop pattern. The basic idea lies in splitting the iteration space of the sequential loop into sets of conflict-free iterations that can be executed concurrently on different processors. As will be demonstrated, this method outperforms existing techniques. Irregular access patterns with different load-balancing and reusability properties are considered in the experiments.
