Many researches have been conducted that retrieved similar trajectories of moving objects in Euclidean space rather than in road network space. However, in real applications, most moving objects are located in road network space. In this paper, we investigate the properties of similar trajectories in road network space and propose a spatio-temporal representation scheme for modeling the trajectories of moving objects. Our spatio-temporal representation scheme effectively converts trajectory from the road network space to the Euclidean space. For measuring similarity between two trajectories, we propose a new POI-distance algorithm which enhances the existing distance algorithm by reducing the insignificant nodes of a trajectory. Theory and experimental results show that this method provide not only a practical method for searching for similar trajectories but also a clustering method for trajectories.","PeriodicalId":193621,"journal":{"name":"2009 Fourth International Conference on Internet Computing for Science and Engineering","volume":"51 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121010335","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 reviews previous works in the area of network damage evaluation. These studies focus on building an index system and computing the damage by the entropy before and after attacks without taking the correlation of index into consideration, which could results in damage increased, and it cannot express the variable of attack damage. This paper measures the damage degree on network availability in the sudden traffic under attack, and then uses dynamic relevant coefficient adjustment method, which combine with real-time network entropy calculation method, to obtain a more accurate reflection during the dynamic process of attack damage.

Therefore, how to ensure personal privacy and get the correct mining results becomes a severe issue to be resolved. In this paper, we propose a kind of random response method of geometric transformation- the combination of the random response technology and the geometric transform algorithm. The algorithm is designed to solve the shortage of low privacy protection of the geometric transform algorithm. The algorithm first gives four parameters, corresponding to the probability of four different types of geometric transformations. According to the various random number generated, different geometric transformation method is selected, which serves the dual effect of privacy protection. Our experiment proves that this method has a high degree of privacy protection and can get correct mining results.","PeriodicalId":193621,"journal":{"name":"2009 Fourth International Conference on Internet Computing for Science and Engineering","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124622187","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}

Low Power Behavioral Synthesis 低功率行为综合

A new parameter called Cycle Power Product (CPP) is defined which captures the power characteristics as an equally weighted sum of normalized mean cycle power. To minimize this parameter uses multiple supply voltages and dynamic frequency clocking and results in reduction of both energy and transient power. The cycle differential power can be modeled either as the mean deviation from the average power or as the cycle-to-cycle power gradient. The switching activity information is obtained from behavioral simulations. Based on the above we develop a new datapath scheduling algorithm which attempts at power and energy minimization by minimizing the CPP parameter during the scheduling process. The type and number of functional units available becomes the set of resource constraints for the scheduler. Experimental results indicate that the scheduler that minimizes CPP instead of conventional energy or average power as objective function could achieve significant reductions in power and energy.","PeriodicalId":193621,"journal":{"name":"2009 Fourth International Conference on Internet Computing for Science and Engineering","volume":"1241 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114057096","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}
