As the demands of high quality visual service have increased recently from consumers, many researchers and companies have focused on the development of multimedia applications based on 3-D models, avatars and animations. However, it will be a difficult work to develop some applications related to 3-D mesh model transmission since they should accept the tremendous amount of transmission data for...

Tree driven mesh is gaining popularity as a viable method to distribute clock with minimum skew in Deep Sub Micron (DSM) technology. In the design of the leaf level mesh, the density of the mesh at various parts of the chip is a crucial factor which decides the clock skew and power dissipated in the mesh. We propose a capacitance driven mesh formation methodology which forms a minimum wire leng...

We present a novel technique for retargetting captured facial animation to new facial models. We use dense motion data that can express fine motions such as wrinkles. We use a normal mesh, which is a special multi-resolution mesh, to represent source and target models. A normal mesh is defined by the base mesh and sequence of normal offsets from it. Our retargetting consists of two steps: base ...

BACKGROUND Biologic mesh is commonly used in abdominal wall reconstruction but may result in increased hernia recurrence. There are minimal data on repair of these recurrent hernias. METHODS We conducted a retrospective chart review of 24 patients presenting to a single surgeon with recurrent ventral hernia, previously repaired with biologic mesh. RESULTS Seventeen of 24 study patients unde...

Determination of the maximum temperature and its location is the matter of the greatest importance in many technological and scientific engineering applications. In terms of numerical calculations of the heat conduction equation by using uniform mesh increments in space, large computational cost is sometimes countered. However, adaptive grid refinement method could be computationally efficient ...

This paper proposes a computational method for fully automated quadrilateral meshing. Unlike previous methods, this new scheme can create a quadrilateral mesh whose directionality is precisely controlled. Given as input: (1) a 2D geometric domain, (2) a desired node spacing distribution as a scalar function deened over the domain, and (3) a desired mesh directionality as a vector eld deened ove...
