For the lack of a proper addressing schema, some published routing algorithms are very complicated and the topological properties of some complex hexagonal and honeycomb related architectures are not well known. In this paper, a unified addressing schema for hexagonal and honeycomb meshes is proposed; two Cayley graphs isomorphic to the two meshes are presented as a formal foundation for the addressing schema. Using the suggested addressing schema, simple distance formulas and concise shortest-path routing algorithms of the two meshes are developed. The routing algorithms may be directly applied in real interconnection networks such as cellular networks. The models based on the unified addressing schema and the two isomorphic Caylay graphs established a concise and elegant foundation to investigate complex hexagonal and honeycomb related networks","PeriodicalId":202629,"journal":{"name":"First International Multi-Symposiums on Computer and Computational Sciences (IMSCCS'06)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126650048","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}

Wavelet coefficients and temporal orientation trees were obtained by utilizing integer wavelet transform to decompose the original data into five layers. Encoding the wavelet coefficient by SPIHT, the bit plane was exported. After encoding the bit plane by adaptive arithmetic encoder yielded higher compression ratio. The method doesn't need float operation and uses the comparability of wavelet coefficients in each scale. Simulation results show that the features of the method were low computation complexity, fast compression rate, high compression ratio and small reconstruction difference, when it is applied to the compression decompression process of temperature signals from a paper mill","PeriodicalId":202629,"journal":{"name":"First International Multi-Symposiums on Computer and Computational Sciences (IMSCCS'06)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127044631","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}

One main drawback of the technique is that a new pixel or patch is selected only considering local information in the generated texture. Thus structural error can't assure to be avoided for structural textures. To accelerate texture synthesis process and to avoid structural mismatch in the output picture, we present in this paper a structural pattern analysis (SPA) algorithm and a texture synthesis method using the algorithm. The pattern analysis tool also quantizes the texture randomness in macro scope view.

Traditional MST problem trying to get a tree with a small tree weight is not fit for ALM. ALM requires the multicast tree has minimum tree diameter, which determines the communicate period of real-time application systems such as DVE and video conferencing system. Based on this point an amended algorithm of Prim algorithm named MDT is presented in this paper. It tries to find a spanning tree for a certain number of nodes with a shortest tree diameter. The algorithm process is discussed in detail and the fake codes are also given out in this paper. A series of simulation experiments had been taken to check the rightness of this algorithm.
