On an automatically parallel generation technique for tetrahedral meshes Summary : In order to prepare modern nite element analysis a program for the eecient parallel generation of tetrahedral meshes in a wide class of three dimensional domains having a generalized cylindric shape is presented. The applied mesh generation strategy is based on the decomposition of some 2D-reference domain into s...

Large-scale wireless testbeds have been setup in the last years with the goal to study wireless multi-hop networks in more realistic environments. Since the setup and operation of such a testbed is expensive in terms of money, time, and labor, the crucial question rises whether this effort is justified with the scientific results the testbed generates. In this paper, we give an answer to this q...

Parameterization of a 3D triangular mesh is a fundamental problem in various applications of meshes. The convex combination approach is widely used for parameterization because of its good properties, such as fast computation and one-to-one embedding. However, the approach has a drawback: most boundary triangles have high distortion in the embedding compared with interior ones. In this paper, w...

This paper discusses the implementation of a distributed geometry for parallel mesh generation, involving dynamic load-balancing and hence dynamic re-partitioning of the geometry. A novel approach is described for improving the efficiency of the distributed geometry interface when dealing with irregular shaped mesh partitions.

The wireless meshed technology is one of the most advanced technology and can be viewed as the technology of the future. This article deals with aspects like performance metrics i.e. delay, R-Factor and Mean Opinion Score (MOS) that have a direct influence on the performance of the wireless mesh network. In this paper voice quality is analyzed in terms of R-Factor and MOS in Wireless Mesh Netwo...

The multi-axis cooper tool is a new tool to create a hex mesh by using multi-axis imprinted sweeps. The tool automatically recognizes applicable geometries and divides them into a hierarchy subvolume, which are then meshed by existing single-axis sweep tools. The resulting meshed volumes, called inlay volumes, contain mesh which is non-conformal or discontinuous at their interfaces. The nonconf...

Objective: The aim of this study was to compare the use of Polypropylene mesh (Prolene) and Sepramesh, a coated Polypropylene mesh with a protective layer of Seprafilm on its visceral side, for the repair of abdominal wall defects in horses. We also aimed to quantify the consequent visceral adhesion and tissue inflammatio Design: Experimental study. Animals: Ten horses. Methods: The horses w...

This paper presents a novel interactive mesh editing approach based on GPU texture mapping. The main feature is that it copies 2D surface geometry information to GPU frame buffer. The planar mesh information is transformed into GPU texture and placed on apposite position of target mesh. 3D information is retrieved after stitching two mesh components from the primitive vertex coordinates. When r...
