The objective is to minimize the total traveling cost. Due to the complexity of the problem, we suggest a tabu search algorithm that combines the features of the exiting local search heuristics. In particular, our tabu search algorithm incorporates the method to reduce the neighborhoods using the proximity information of the Voronoi diagram corresponding to each problem instance. Computational experiments are done on the benchmark problems and the test results are reported.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"77 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120843011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous image reprojection methods often run on the CPU, but these approaches take high-cost for rendering. We present a real-time image reprojection method using the GPU entirely. From given a reference image and its depth image of the scene prerendered, we generate novel images at arbitrary view points without the original geometry data. We render a simple plane at a novel view, and for each pixel being rendered, we make a ray that faces the opposite direction of the view. Then, we transform the ray to reference image space and trace the ray through a depth image to find an intersection, using a recently proposed method. In our experience, we archived tens of frames per second and it was independent from the complexity of the scene.","PeriodicalId":386960,"journal":{"name":"2007 International Conference on Computational Science and its Applications (ICCSA 2007)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125157626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The requirements of security characters are not always constant and the security specifications will need to modify according to the security requirements, however, there is no a uniform formal foundation to support numerous security specifications, it will block the application of these security policies, which have not been deeply investigated so far. To solve these problems, in this paper, we advocate to apply Spi calculus to describe and reason the security properties, for convenience describe and reason we separate security into security enhancing capability and security limiting constraint. Meanwhile we find the original Spi calculus can't completely to solve the properties in security-aware Web service composition. In success, we extend the syntax and semantic of Spi calculus, named SpiWeb calculus, to adapt the security-aware dynamic web service composition.

We show that in contrast to one- dimensional solitons, collisions between two lump solitons are far from elastic.
