Meanwhile, the old structure has been improved; the problem of product configuration is abstracted to combination problem, which remarkably improved the efficiency of model solving. Secondly, the definition and expression of constraint relations among parts is studied. By using graph-theory the constraint matrix was proposed. Then, the solving of a new model is studied. Finally, a simple example is given to show the solving process of the new structure model and prove its feasibility.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114321186","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}

A good simulator can save memory and times. There are many simulators developed, but most of those simulator aimed at performance and data schedule algorithm.

This simulator was originally intended to do manipuility modeling of storage network system. Over time it has been extended and generalized so that it can simulate several kinds of storage systems by change the configure file.

In order to satisfy the need of real time human hand tracking, a novel features extraction approach, aimed at optimization of processing speed, is put forward in this paper. First of all, the hand contour is approximately described by a polygon with concave and protruding, and the relationship between hand gesture polygon and its bounding box is studied. Secondly, a hand gesture contour algorithm(HGCA) is proposed to obtain the hand gesture polygon. Then, based on the HGCA, the approaches to gain the several main feature points are presented, including fingertips, roots of fingers, joints and the intersection of knuckle on different fingers. Finally, some of the comparison experimental results are presented. The main advantages of human hand features extraction put forward in this paper consist in its controllable precision and low time complexity.","PeriodicalId":228533,"journal":{"name":"2008 International Symposium on Computer Science and Computational Technology","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115397446","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}
