In the paper an algorithm of triangle mesh generation for a full three-dimensional volumetric data is presented. Calculations are performed in real time using graphics processors. The method is very well suited for the visualization of dynamic data, as the calculations use only the current frame data (not including data from previous frames). Due to high performance of the algorithm, it can be ...

A new e-Service model called dynamic supply chain is characterized by their dynamic nature in easily being formed and disbanded with the seamless connectivity provided by e-Marketplace. The new term “supply mesh” was coined to represent this virtual community of companies in which dynamic supply chains, as per project (also known as make-toorder), are formed across different tiers of suppliers....

In this paper, we propose a new scheme to represent threedimensional (3-D) dynamic scenes using a hierarchical decomposition of depth maps. In the hierarchical decomposition, we split a depth map into four types of images: regular mesh, boundary, feature point and number-oflayer (NOL) images. A regular mesh image is obtained by down-sampling a depth map. A boundary image is generated by gatheri...

In this paper, we propose a new integrated framework for joint routing and rate adaptation in multirate multi-hop wireless networks. Unlike many previous efforts, our framework considers several factors that affect end-to-end performance. Among these factors, the framework takes into account the effect of the relative positions of the links on a path when choosing the rates of operation and the...

The joint bilateral filter, which enables feature-preserving signal smoothing according to the structural information from a guidance, has been applied for various tasks in geometry processing. Existing methods either rely on a static guidance that may be inconsistent with the input and lead to unsatisfactory results, or a dynamic guidance that is automatically updated but sensitive to noises a...

We present an overview of algorithms and data structures for dynamic re nement/coarsening (adaptation) of unstructured FE meshes on loosely coupled parallel processors. We describe a) a parallel adaptation algorithm, b) an online parallel repartitioning algorithm based on mesh adaptation histories, c) an algorithm for the migration of mesh elements between processors, and d) an integrated objec...

aims: the installation of intravenous catheter is an unpleasant and painful experience for many patients. then, it is necessary to provide new methods to either reduce or remove pain in the patients’ injection point. the aim of this study was to investigate the effects of positioning (either sitting or lying) during the installation of intravenous catheter on pain level and the following anxiet...

Time-accurate fluid-structure interaction simulations of strong shock and detonation waves impinging on deforming solid structures benefit significantly from the application of dynamic mesh adaptation in the fluid. A patch-based parallel fluid solver with adaptive mesh refinement in space and time tailored for this problem class is presented; special attention is given to the robustness of the ...

A WDM mesh network is planned and designed so that to satisfy all its demands. Each connection has to be protected with the a) dedicated way, b) shared way and c) the benefits of the shared way versus the dedicated way are also showed. The shortest path algorithm is used for all dynamical cases. The network uses wavelength conversion. Keywords-dedicated protection, optical channel layer, shared...
