Because of the ability to listen to the multi-user relay service, we need to optimize and select user group of physical network coding. In this paper, we use over-hearing mechanism in order to optimize user group, even more we also need to improve the department of transport protocol on delay. At last, depending on improved transport protocol, we design two kinds of frame structure which could adapt to improved transfer model. The simulation result shows that PNC-DF and PNC-AF with over-hearing mechanism could reduce the bit error rate.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123816111","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, the current solutions are mostly confined to the enforcement of several patchy-works on system which still requires proficient hacking skills for administrators and cannot ensure continuous protection for VM, resulting in potential security risks. In this paper we present a framework (VNSS) which provides both guarantee of distinct security level requirement and full-lifecycle protection for VM.

In this paper we present a decentralized algorithm to construct network coding solutions, which reduces the number of coding nodes. We showed the dynamic topology greatly affected the network coding solutions, which may improve coding solution or reduce the coding nodes and we also analyzed some useful behaviors in feasible network coding solutions. By the nodes independently attempting those behaviors in dynamic topology, we introduce a fully decentralized algorithm of constructing coding solution. By simulation we found our approach has excellent performance, which achieves the approximate throughput compared to completely Randomized Network Coding, but only employing 10%–20% of nodes to code.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132786322","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 utterance image sequences of isolated Chinese words are recorded with a head-mounted camera, and we use Convolutional VEF snake model to detect and track lip boundary rapidly and accurately. Geometric and motion features are both extracted from lip contour sequences and concatenated to form a joint feature descriptor. Canonical correlation is applied to measure the similarity of two utterance feature matrices and a linear discriminant function is introduced to make further improvement on the recognition accuracy. Experimental results demonstrate that our approach is promising and the joint feature descriptor is more robust than individual ones.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133711435","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 passive synthetic aperture technique can increase the array aperture artificially by the motion of physical array and signal processing. This paper applies it to the near-field ranging with focused beamforming, which provides a feasible ranging method for near-field weak signal. Theoretical analysis and simulation results both indicate: 1) the proposed method can achieve high ranging precision for near-field sources; 2) because of the error accumulation, the times of extending array would affect the ranging precision directly, and if the sizes of synthetic apertures are same, the fewer times array is extended, the better performance it owns, on the contrary, the ranging precision is independent on the speed of the towed array.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":"758 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122986179","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}

In this paper, the theory of semi-fragile watermarking based on properties of JPEG and DCT coefficients are introduced, and the parameters that affect the performances are analyzed theoretically and experimentally. The result of study shows that the positions of DCT coefficients used to generate watermark, the number of watermarks generated from a couple of blocks and the positions used to hide watermarks have great effect on the performances of the algorithm. Unless some special requirements exist, both the positions of coefficients used to generate and embed watermark should be chosen according to the order of zig-zag, and usually the best performance can be obtained when only one bit watermark is generated from a couple of blocks.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115888412","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}

In this paper, a learning method is proposed named AdaGP-Rank by applying boosting techniques to genetic programming. This approach uses genetic programming to evolve ranking functions while a process inspired from AdaBoost technique helps the evolved ranking functions concentrate on the ranking of those documents associating those ‘hard’ queries. Based on the confidence coefficients, the ranking functions obtained at each boosting round are then combined into a final strong ranker. Experiments conform that AdaGP-Rank has general better performance than several state-of-the-art ranking algorithms on the benchmark data sets.","PeriodicalId":179847,"journal":{"name":"2010 IEEE Youth Conference on Information, Computing and Telecommunications","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132535298","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}
