One of these approaches, an integrated spreadsheets software, has been used in recent years in a logistics systems management course with a large enrolment at a major university. The article illustrates how, under the integrated paradigm, various computer software packages are integrated in the course to form a unique learning environment. At the last of the article, we give an illustration of the use of Microsoft Excel in inventory control.","PeriodicalId":303484,"journal":{"name":"2009 4th International Conference on Computer Science & Education","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122669311","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, an unequal load on the cluster head nodes results in the problem of unbalanced energy consumption, which reduces network lifetime. We propose a nonuniform density (NUD) model for wireless sensor networks and study the optimal node deployment scheme in theory. Simulation results show that NUD can maintain more equal energy dissipation among the cluster heads and obviously prolongs the network lifetime.","PeriodicalId":303484,"journal":{"name":"2009 4th International Conference on Computer Science & Education","volume":"885 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123033611","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}

Six years later, IMS-LD is no longer evolving while facing an increasing number of critiques. The specification is still not implemented by any leading brands in the e-learning industry. The current development of new IMS specifications offers a window of opportunity to rethink IMS-LD. After discussing IMS-LD, trying to understand the existing critiques and analyzing the new technical context, this paper proposes the guidelines for the creation of this new learning design specification. This specification would be split in two specifications satisfying both the instructional designers and the learning platform developers and vendors. The specification optimized to learning platform vendors, called Simple Learning Design 2.0 will be designed to ease the deployment of the learning design concepts in the existing Learning Management Systems. SLD 2.0 is currently developed in the context of the SynergiC3 project.","PeriodicalId":303484,"journal":{"name":"2009 4th International Conference on Computer Science & Education","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128090074","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 mainly discusses the reconstruction method of triangle model for machine elements based on industrial CT (ICT) slices. Matching degree is adopted to match the material-edges on the matching material-region. By constructing a feature functions with matching degree, a matching material-edge sequence is divided into several edge sequences which respectively constitute an identical surface (plane, cylinder, cone, and sphere). To improve the quality of reconstruction, the geometric parameters of material-edges are calculated repeatedly by intersection with slice plane and recognized surface. Finally, the model is obtained by constructing triangles between two matching material-regions and arbitrary planar polygon with a rapid algorithm.","PeriodicalId":303484,"journal":{"name":"2009 4th International Conference on Computer Science & Education","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133414685","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}

Through constructing the new procedure flow chart, the algorithm optimizes the selection paths using Fibonacci law, and generates test data for assigned branch. When the branch predicates of the chosen path are linear representation, solve the linear restraint set directly to generate test data, otherwise determine that the path is inaccessible; When the branch predicate composing of nonlinear expression, linearize nonlinear function by using the divided difference approximate derivative to ensure the test data can easily generated through simple iteration, or conclude that path is inaccessible to a large extent. If the chosen path is to a large extent inaccessible or inaccessible, then a new path is selected, repeat the above process until the desired data obtained, if no new path was chosen, then the specified branch was inaccessible.

But the general personal credit rating assessment system of commercial bank can not make the correct credit rating because the lender, college students, have no credit history. To avoid the credit risk, a rational credit assessment system must to be established for college Students. With the self-learning, self-organizing, adaptive and nonlinear dynamic handling characteristics of Artificial Neural Network, a Back Propagatio neural network was developed to evaluate the credit rating about a college student. Several samples, which were provided by a bank, were used for network training and testing by MATLAB. The maximum value of the error between the prediction value of the network and actual value is only 2.92%. Simulation results demonstrate that the algorithm developed is fairly efficient for the assessment about the college student's personal credit situation.","PeriodicalId":303484,"journal":{"name":"2009 4th International Conference on Computer Science & Education","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133988601","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}
