Based on the r-row-matching algorithm, we propose a two-stage r-row-matching algorithm. According to the concept of immunity, the immunity process and mechanism, we design self-set and detector-set by using a sliding window. On this basis, the self-set, the detector-set and other generating algorithm, as well as the algorithm of detector-set training are implemented. Finally, based on the data structure of sliding window, the string recognition algorithm is implemented. Experiments show that the algorithm can effectively carry out string identification.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121244973","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 M-SSR, a path is divided into multiple segments, in each of which multiple node-disjoint paths are discovered and routing maintenance can be performed independently. The proposed protocol can decrease congestion, optimize bandwidth and improve the sharing rate of channel by using multiple paths to transmit data packets in parallel. It uses segment-by- segment scheme to decrease routing control overhead and improve the network scalability. Simulation studies show that the proposed protocol can balance the load of the network and can be adaptive to the change of the network topology effectively, and also improve the survivability, stability and success ratio for routing.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124761731","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 dynamical properties of the CNDpsilas are difficult to deal with. The local activity principle of the Cellular Nonlinear Network (CNN) introduced by Chua has provided a powerful tool for studying the emergence of complex patterns in a homogeneous lattice formed by coupled cells. Based on the Rossler equation introduced by Rossler, this paper establishes a two dimensional coupled Rossler CNN system. Using the analytical criteria for the local activity calculates the chaos edge of the Rossler CNN system. The numerical simulations show that the emergence may exist if the selected cell parameters are nearby the edge of chaos domain. The Rossler CNN can exhibit periodicity and chaos.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"451 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125782726","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}

Firstly, some existing solutions for this problem are analyzed, and some shortages and flaws are pointed out. Secondly, regularities of distribution of the summation of multiple independent random numbers with same and different distributions are analyzed and formulated by data simulating and fitting. Furthermore, an algorithm named DOPS_Const for the OPS with an additive arc weight is proposed based on the above analysis, and the randomness and subjectivity in path selection can be avoided according to the algorithm. Finally, the theoretical and statistical probabilities of the selected path satisfying the given constraint are compared, and our algorithm is feasible and valid to solve the OPS with constraint in the dynamic networks.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123224600","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}

This paper proposes a novel software architecture testing technology using pi calculus. pi calculus is of rigorous mathematical foundation and well-defined semantics. Petri net provides a graphical description technique that is easy to understand and carry on analysis. We make pi calculus combined with Petri net and propose mapping relationship based on them. Then we will introduce pi Behavior Graph using the mapping relationship and pi-ADL that takes its roots in previous works concerning the use of pi calculus as semantic foundation for architecture description languages. We propose seven testing coverage criteria from black-box and white-box perspectives and give its formal description in piBG respectively. At last, we build a prototype tool that implements the pi-ADL approach to the specification of software architecture and generates test paths. We use TRMCS as a typical architecture model to illustrate our testing technology.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125525813","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, we propose an automatic degraded video detection approach based on support vector machine and template matching to detecting mosaic block in video. We develop a detection algorithm based on a cascade of processing steps as follows. First, we use DWT to remove the vertical high frequency of a frame and use the Canny edge algorithm to detect the frame. Second, we use the template matching to find the candidate mosaic block coordinate. Third, a SVM classifier is employed to distinguish mosaic block from the candidate ones. When the number of mosaic block is higher than a threshold, we can regard the frame as the frame with mosaic block. Experimental results show that the proposed algorithm has good performance.","PeriodicalId":370660,"journal":{"name":"2008 The 9th International Conference for Young Computer Scientists","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122407756","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}
