Because different customers have different needs and expectations in different aspects of the service and due to the customer's self-property, trading amount, trading time, trading evaluation and trading risk perception factors, etc. The trust assessment among customers is hard to measure and difficult to give accurate quantification. In order to solve the problem, in this paper, a customer trust network model based on the above factors and combined with cognitive theories and methods of e-Business is implemented and three strategies, customer occupation based construction strategy, customer domain based construction strategy and customer occupation and domain based construction strategy, are used for constructing trust network. During the construction process, the method of trust computation in each strategy is introduced. The Experiment results show that the model and these strategies can reduce the complexity of trust relationship and with guaranteed trust value as a premise, improve the coverage rate of trust network.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131411806","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 SISOMH wireless channel, where artificial noise is utilized, is designed to prevent eavesdropping. But the artificial noise may be invalid due to the inherent security weakness. We point out that the SISOMH scheme is not safe through by matrix analysis.

A radar and infrared weighted fusion algorithm based on unscented Kalman filter (UKF) was proposed. The algorithm which solved the nonlinear function of the measurement model approximates the probability density distribution of the nonlinear function instead of approximating the linear function used in extended Kalman filter, thus it avoids the filter divergence problem in model linearization. Simulation results show that this algorithm has good convergence properties, high fusion precision, good robustness and good real-time performance, so it meets the need of information fusion of radar/ infrared compound guidance.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122968526","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}
