This method is often useful in understanding how a particular class of genes functions together during a biological process. In this study, we attempted to perform clustering using the Markov cluster (MCL) algorithm, a clustering method for graphs based on the simulation of stochastic flow. It is a fast and efficient algorithm that clusters nodes in a graph through simulation by computing probability. First, we converted the raw matrix into a sample matrix using the Euclidean distance of the genes between the samples. Second, we applied the MCL algorithm to the new matrix of Euclidean distance and considered 2 factors, namely, the inflation and diagonal terms of the matrix. We have turned to set the proper factors through massive experiments. In addition, distance thresholds, i.e., the average of each column data elements, were used to clearly distinguish between groups. Our experimental result shows about 70% accuracy in average compared to the class that is known before. We also compared the MCL algorithm with the self-organizing map (SOM) clustering, K-means clustering and hierarchical clustering (HC) algorithms.","PeriodicalId":155998,"journal":{"name":"2008 IEEE 8th International Conference on Computer and Information Technology Workshops","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121095744","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}

Like traditional Web objects, rich media objects can benefit from proxy caching, but caching streaming media is more of challenging than caching simple Web objects, because the streaming media have features such as huge size and high bandwidth. Due to huge size of streaming media, lots of researches manage the contents with segments for efficient storage management. And to support various bandwidth requirements for the heterogeneous ubiquitous devices, a transcoding proxy is usually necessary to provide not only adapting multimedia streams to the client by transcoding, but also caching them for later use. In this paper, we propose the hybrid segmentation strategy for the transcoding proxy that is uniform segmentation in the same version and is also exponential segmentation among the multiple versions. This strategy reduces the replacement count than uniform segmentation and gets the similar performance to uniform segmentation. The performance results show that hybrid segmentation with aggregated profit function have a high delay saving ratio, high byte-hit ratio and less transcoding data.","PeriodicalId":155998,"journal":{"name":"2008 IEEE 8th International Conference on Computer and Information Technology Workshops","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125216829","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}

Many Trojan Horses and viruses use the security holes of exception to trigger attack, such as buffer overflow attack. Although most embedded systems rely on the programmer, the compiler or the third-party security software to defend and protect the systems against the buffer overflow attack, these techniques could not completely maintain the overall system security. Using a secure programming language is another approach to protect the system, but this approach contains a large security hole that break the overall security. Therefore, this paper proposes a secure Java embedded processor architecture called jHISC with protection logic to protect the system naturally. This new processor realized the natural secure language features of Java in the core architecture to enhance the overall system security. It performs various rigid hardware bound checks and embedded access control checks to avoid the code bypassing. The current implementation phase is under version 4 with 4 KB instruction cache and 8 KB data cache is described by VHDL and implemented and verified in a Xilinx Virtex FPGA.","PeriodicalId":155998,"journal":{"name":"2008 IEEE 8th International Conference on Computer and Information Technology Workshops","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133737826","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}
