A hybrid methodology PSACO (particle swarm ant colony optimization) combining particle swarm optimization with ant colony optimization algorithm is applied to solve the model. Both particle swarm optimization (PSO) and ant colony optimization (ACO) are co-operative, population-based global search swarm intelligence meta-heuristics. PSO is inspired by social behavior of bird flocking or fish schooling, while ACO imitates foraging behavior of real life ants. In this study, we employ a pheromone-guided mechanism to improve the performance of PSO method. Additionally, the model is implemented on the demonstrated research of the index stock of index 30, the result could provide scientific foundation for security investment.","PeriodicalId":103284,"journal":{"name":"2008 International Symposiums on Information Processing","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132960072","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}

Based on the characteristics of the LU Factorization, this paper presents a novel robust watermarking algorithm in wavelet domain of digital image. Firstly, the original image will be transformed into wavelet domain by DWT, and the level of which is decided by the volume of watermark information. Next to do is computing the variances of the last details, and select detail matrix information whose variance is the max one among details. Then it will be preprocessed, if the image matrix is singular matrix, it will be converted into a non-singular matrix by permutation matrix which can be as a key; Secondly, the preprocessed image is decomposed into two triangular matrices including the upper one and the lower one with 1's on the main diagonal, and which have good distribution; Finally, the scrambled meaningful watermark is embedded into the non-zero pixels of two triangular matrixes adaptively. The experimental results show that the algorithm is simple, with better robustness and security.","PeriodicalId":103284,"journal":{"name":"2008 International Symposiums on Information Processing","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124096632","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 first Family of methods takes a two-step strategy, extracting some reliable negative examples, and then applying the supervised or semi-supervised learning method. The second family of methods estimates statistical queries over positive and unlabeled examples. The third family of methods reduces this problem to the problem of learning with high one-sided noise by treating the unlabeled set as noisy negative examples.

So, to build an unified query interface which integrates query interfaces of a domain to access various Web databases at the same time becomes a very important issue. In this paper, the schema characteristics of query interfaces and common attributes in a same domain are firstly analyzed, and it also gives a new representation of query interface, then the definition of \"Form term\" and \"Function term\" are proposed ,and a new similarity computing algorithm, literal and semantic based similarity computing (LSSC) is proposed, which is based on the two definitions. Secondly, a clustering algorithm for Deep Web query interfaces is given by combining LSSC and NQ algorithm: LSSC-NQ.

Some researchers discuss access control from new point of view. Trust has natural connection with access control. It will promote development of access control to use trust. There is a kind of access control problem we call ldquogamblingrdquo access control. After provider of service affords service to requestor, probability that provider gets designed results is close to probability that provider gets undersigned results. Faced to request, provider has to gamble. The traditional access control could not resolve this kind of problem. On the contrary, trust-based access control is suitable for this problem. In this paper, based on social cognitive theory, we design a trust-based access control (TBAC) with feedback. Based on providerpsilas goals, TBAC looks on trust to requestor as standard to whether give requestor the corresponding warranty or not. Besides, we use environment, feedback, and forecast, to realize adaptability.","PeriodicalId":103284,"journal":{"name":"2008 International Symposiums on Information Processing","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117192097","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}

Thus, collaborations in enterprises emerge as the times require. Along with the benefits brought by these kinds of collaborations, the risks arising in the cooperation process produce extra costs as well. Therefore, cost control is extending from the internal microscopic focus to the external interactive processes. The traditional cost control methods have limitations in coping with the new risks resulted from the supply chain. By taking into account the external risks level, this paper constitutes a cost control model based on supply chain operational risks which has improved the Activity-based costing and put forward a new perspective in supply chain cost optimization.","PeriodicalId":103284,"journal":{"name":"2008 International Symposiums on Information Processing","volume":"26 Pt 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114598902","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}
