On the other hand, the disappearance of market opportunities at any time doesn’t permit the longer decision time for tally companies. Therefore, when confronted the account sale opportunity, it is meaningful to choose a correct decision at the right time for tally companies. In this paper, under information entropy and dynamic planning theory, the probability of contract-violated enterprises relevant to the tally company along with the disappearance probability of market opportunities would be fully taken into consideration, decision model on optimal stopping of the account sale under imperfect information has been established. Meanwhile, we conclude the decision rules in order to enhance the scientific probability and the accuracy of the decision.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129826823","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 compound Chaos algorithm combines the Lorenz Chaotic system and Logistics map to generate the pseudo-random sequences. Then the pseudo-random sequences are used to produce the permutation matrix to encrypt the digital image. Matlab is used for simulation testing of the image encryption. Algorithm safety is analyzed from three aspects including the histograms comparison between original image and encrypted image, correlation coefficients of original image and encrypted image, and secret key space analysis. The experimental results indicate that the proposed encryption approach is valid and it can expand the secret key space and improve anti-aggressive ability. The compound Chaos algorithm can be also used for color digital image encryption.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127328244","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 algorithm usually uses straight-line ray tracing, so the projection matrix will never change once the model is built. In order to improve the accuracy of ART and eliminate phenomena that the wave velocity of the units around anomalous body is far from the true value, The shortest path ray tracing (SPT) is introduced into ART and is modified. Before each iteration, the projection matrix is anew computed through using SPT ray tracing. After each iteration, the wave velocity of the normal uints is smoothed. Computer simulation and concrete model of ultrasonic computerized tomography show that the combination of SPT ray tracing and ART is effective to control wave velocity dispersion and improve the accuracy of computation and the quality of image reconstruction on concrete.","PeriodicalId":393802,"journal":{"name":"2010 International Forum on Information Technology and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130930595","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 research, we present an efficient algorithm for collision detection using a dual bounding hierarchy which consists of an discrete orientation polytopes (k-DOPs) tree enhanced with bounding sphere.

The remaining objects are in close proximity are tested using separation axis, where some separation axis are more effective and should be chosen first.
