Researchers attempt to alternatively present new ways of learning. Computer-Aided Instruction (CAI) programs have been introduced in many fields. The 3D Covalent Bonding Molecular Structure Stimulating Program is one of the CAI programs in studying basic molecular structures for undergraduate students. Open source software packages are selected to construct the program in order to support the boundless delivery of knowledge. It simulates most of the covalent bonding molecular structures with dynamic inputs. Experimental tests have been performed to confirm students' satisfactory. The experimental tests included 46 undergraduate students and the overall satisfactory result of 82.70%.","PeriodicalId":299461,"journal":{"name":"2010 2nd International Conference on Education Technology and Computer","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122555741","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 the face of the large number of websites, traditional web crawlers cannot function well to get the relevant pages effectively. To solve these problems, focused crawlers utilize semantic web technologies to analyze the semantics of hyperlinks and web documents. The focused crawler is a special-purpose search engine which aims to selectively seek out pages that are relevant to a predefined set of topics, rather than to exploit all regions of the web. The main characteristic of focused crawling is that the crawler does not need to collect all web pages, but selects and retrieves only the relevant pages. So the major problem is how to retrieve the maximal set of relevant and quality pages. To address this problem, we have designed a focused crawler which calculates the relevancy of block in web page. The Block is partitioned by VIPS algorithm. Page relevancy is calculated by sum of all block relevancy scores in one page. It also calculates the URL score for identifying whether a URL is relevant or not for a specific topic.","PeriodicalId":299461,"journal":{"name":"2010 2nd International Conference on Education Technology and Computer","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122611287","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}

According to the theory of projective transformation, the vanishing point's coordinates can be obtained, after that, combined with the corollary of Laguerre theorem: the infinity points of which the two mutually perpendicular lines and their circular points harmonic conjugate, the image coordinates of the circular points can be obtained. In the experiment, using the positive tri-prism as the experimental object and according to the same primal and the cross-ratio invariance, the coordinates of infinity points can be obtained. Then, according to the corollary of Laguerre theorem, the corresponding coordinates of the circular points can be got.

STP uses a single tree for the entire network which may result in inefficient bandwidth allocation since the non-spanning-tree links will not carry traffic at all. As a solution, the IEEE 802.1s working group has introduced a Multiple Spanning Tree Protocol (MSTP) that allows a switch to participate in multiple spanning trees, one tree per group of VLANs. In our previous work, we introduced a graph theoretic approach named Best Multiple Spanning Tree (BMST) algorithm for ranking all of the possible solutions for selection of the proper trees in a network running MSTP and for finding the best solution based on load balancing on links and switches. Although, BMST algorithm can find the best answer for small networks, but its complexity is too large in large scale networks. In this paper, we propose a simple approach named Multiple Best Spanning Tree (MBST) to reduce the computational complexity of the BMST.","PeriodicalId":299461,"journal":{"name":"2010 2nd International Conference on Education Technology and Computer","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129511514","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}
