Mesh compression is an important task in geometry processing. It exploits geometric coherence of the data to reduce the amount of space needed to store a surfacemesh.Most techniques perform compression employing a uniform data quantization over the whole surface. Research in shape perception, however, suggests that there are parts of the mesh that are visually more relevant than others. We pres...

We especially study the surface tension of compressed nuclei and compression effects on the fission barrier. We analyse the consequences of this statical calculation on the dynamics of a vibrating nucleus using a h~drodynamical approach. In addition we present compression properties of excited homogeneous nuclear matter starting from a Fermi gas model. Nuclear experiments now are performed in a...

HTTP compression is an essential tool for web speed up and network cost reduction. Not surprisingly, it is used by over 95% of top websites, saving about 75% of webpage traffic. The currently used compression format and tools were designed over 15 years ago, with static content in mind. Although the web has significantly evolved since and became highly dynamic, the compression solutions have no...

Piers were important structural members between superstructure and foundation of bridge which designed to transfer resist the vertical loads horizontal (dead load structure, traffic loads, water pressure, ice, wind) foundation. The objective this study was evaluate effect number piers in transverse direction (horizontal distance or spacing) on static dynamic responses for two types bridges stru...

In addition to force-body interaction problems, deformable bodies problems are quite common in engineering applications and their investigations more complex. The friction force contact pressure formed between the surfaces dominant mostly studies investigated considering static quasi-static conditions. However, elastic/elasto-plastic deformation dynamic conditions, geometric surface shape is im...

The effect on elastic stockings on ambulatory venous pressure was investigated in 22 limbs with deep venous insufficiency. The failure of some elastic stockings to reduce the ambulatory venous pressure in some limbs is due to the lack of graduated compression, which is caused by ankle-calf disproportion--narrow ankles and wide calves. This can be recognised by using the pressure-girth profile a...

This article deals with video sequence compression for very low bitrate. We assume static scene captured with a monocular moving camera. We propose a method using several 3D models in order to reconstruct the original video sequence or a virtual one. A complete scheme for video sequence compression is presented and compared with classical compression schemes.
