To improve the performance of LDPC codes, a simple and effective method to construct QC-LDPC codes without short cycles (cycles of length four and six) is proposed. The approach is especially effective when the parity-check matrix of QC-LDPC codes is composed of circulant permutation matrices. Firstly, we analyze the shapes of the cycles in the exponent matrix, to get the required conditions of no four-cycles and six-cycles. Then we show how to construct the parity-check matrix without four-cycles and six-cycles by filling rows of the exponent matrix with arithmetic sequences. Simulation results show that the proposed codes have better performance than array codes. Though the performance of the proposed codes is not as well as random codes at higher Eb/N0, they can be applied to practical communications because of being encoded in linear time with shift registers.","PeriodicalId":208089,"journal":{"name":"2012 Fourth International Conference on Multimedia Information Networking and Security","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115322066","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}

However, traditional black box fuzz testing tools, which randomly mutate the input, are blind and ineffective. The white box fuzzing technology, known as the symbolic execution, is still facing the problem of low efficiency and path explosion. We present a new automated fuzzing technique based on comprehensive evaluation and a tool, Rank Fuzz, that implements this technique. By running dynamic taint analysis, we divide the input into several fields and make a rank to each of them according to the comprehensive evaluation results, in the hope that the potential vulnerability can be quickly found. We use several existing vulnerabilities to assess the reasonability of our evaluation system, finding that Rank Fuzz can effectively locate the bytes triggering the vulnerabilities and all of their ranks are on the top 30% of total fields. We also test two off-the-shelf applications within 8 hours and find 3 new vulnerabilities.","PeriodicalId":208089,"journal":{"name":"2012 Fourth International Conference on Multimedia Information Networking and Security","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127930450","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}

Considering these factors, the improved item prediction approaches present a more rational method to measure user's rating scale, take item objective character into consideration in the processing of prediction.

We propose a new language - Multimedia Mash up Markup Language (M3L) - that enables flexible access and easy combination of multimedia content. We first describe state-of-the-art in mashups before presenting our proposed language, while emphasizing its distinct features compared with state-of-the-art.
