In order to enhance the virtual manufacture of paste simulation for PCB circuit modular, it is essential and critical for virtual reality simulation to build 3D model for the mounting machine in an efficient and accurate way. Based on the modeling principles, we have done extensive research on critical techniques on VRML geometric modeling. We have proposed the VRML based method that utilizes several modeling tools to build the geometric models efficiently. Using the boom mounting machine as an example, we have focused on the interior and the exterior cases of the mounting machine, to illustrate the construction of its static model that is based on VRML. The result of the simulation has proved the efficiency of the modeling methodology. The models generated have high degree of fidelity. This paper has built the foundation for visual system of mounting machine.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126373922","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 develops a Dual-Controller system which adds the hardware level redundant relative to Single-Controller system, so it has high stability and reliability in the level of disk and controller. It can satisfy the requirements of storage service stability of higher industry. The Dual-Controller system uses the special heart module between the controllers for communication. So when the system is running, one controller is always getting the mirror controller's state, which helps to detect the fault when the mirror controller is fault. We create the CACHE module to maintain two types of data of CACHE and MIRROR. The experimental result shows the performance of Dual-Controller system is almost the same with the Single-Controller system, but the Dual-Controller system won't loss the data and can continue to provide data services.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127940283","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, traditional association rules are mostly based on the support and confidence metrics, and most algorithms and researches assumed that each attribute in the database is equal. In fact, because the user preference to the item is different, the mining rules using the existing algorithms are not always appropriate to users. By introducing the concept of weighted dual confidence, a new algorithm which can mine effective weighted rules is proposed in this paper, which is on the basis of the dual confidence association rules used in algorithm. The case studies show that the algorithm can reduce the large number of meaningless association rules and mine interesting negative association rules in real life.","PeriodicalId":269967,"journal":{"name":"2012 Fourth International Conference on Computational and Information Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130450933","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}
