TL;DR: The solution proposed and adopted during this project was based on the establishment of trusted third party services (TTPS) based on secure session layer (SSL) which was demonstrated and validated using an existing telemedicine platform.

TL;DR: This paper investigates the potentials of the loops parallelization techniques using dynamic loop analysis techniques, and intends to use it exclusively in cases when static analysis fails to give any answer, and only if the user asserts its applicability.

TL;DR: This paper presents an alternative lightweight approach called Selective- MPI (S-MPI), which was designed to enhance the efficiency of the scheduling of applications on an MPI implementation environment.

TL;DR: It is shown that metacomputing environments can be used to enable a more powerful and unified computational infrastructure for telemedicine and the Globus metacOMputing toolkit can provide the necessary low level mechanisms to enabling a large scale telemedical infrastructure.

TL;DR: The main features of the CARPET language and its practical use for programming three-dimensional models of the contamination of soils developed in the CABOTO project are described.

TL;DR: A hybrid algorithm for circuit partitioning, which uses tabu search to improve the simulated annealing meta-heuristics, is proposed and compared with puretabu search and simulatedAnnealing algorithms, and also with a genetic algorithm.

TL;DR: The development of the virtual temporal bone is described, a new method of teaching the complex anatomy of the middle and inner ear utilizing virtual reality and current networking technology.

TL;DR: This paper presents the research activities in virtual reality (VR) applications at the Iowa Center for Emerging Manufacturing Technology at Iowa State University and presents the most recent applications, currently under development.

TL;DR: It is shown that an immersive virtual environment such as the CAVE aids in the interactive exploration of the large scale and time dependent data sets that result from these simulations.

TL;DR: The motivation for this work is to develop an alternative technique to visualise the inner mucosal surface of the colonic wall using 3D visualisation and virtual reality to perform virtual endoscopy.

TL;DR: Two methods of P pattern L layer ANN learning on n × n RMESH have been presented and one required memory space of O(nL) but conceptually is simpler to develop and the other uses pipelined approach which reduces the memory requirement to O(L).

TL;DR: An overview of the ParFlow method is given, and the design and the implementation of ParFlow++, an object-oriented irregular parallel software for urban outdoor radio wave propagation prediction prediction is reported.

TL;DR: A two-way parallel recursive method is presented for solving a tridiagonal linear system based on the parallel segment recursive method proposed in [9].

TL;DR: It is shown that the use of virtual environments for computational steering interfaces can improve interaction with the simulation and immersion in the computational process.

TL;DR: Parallel implicit iterative solution techniques are considered for application to a compressible hypersonic Navier-Stokes solver on unstructured meshes and two types of non-overlapping preconditioners are presented and compared.

TL;DR: A simplified three-dimensional cytokinetic simulation model of tumour growth in vitro has been developed and its application to the model has led to a spectacular three- dimensional visualization of both the external and the internal structure of a growing tumour spheroid.

TL;DR: This paper reports on the remote use of MIMD parallel machines for compute-intensive visualisation tasks and progressive refinement and latency hiding techniques are proposed as a method of reducing the latency of a distributed rendering system.

TL;DR: The working principles of the VEplatform system and its performance are discussed and it is shown that the system retains a simple structure.
