Some education experts think the multimedia courseware in education is indeed necessary, but others hold different opinions. These questions are still critical problems unsolved for us all who are working in front-line of high education fields. It is acknowledged that, in one hand, the multimedia courseware aided teaching will certainly benefits the development of our high education, in the hand, it will degenerate the central role of the teacher. In this paper, we focus on some proposing strategies of seeking the balance of advantages and disadvantages of course teaching via multimedia courseware. Strategies proposed here provided some practice reference for those who are attempting to combine these two styles with information technology in more optimal ways.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125349477","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 network, amino acids are vertices and the interactions between them act as edges. The networks of 80 proteins that belong to four structural classes are constructed at three length scales: Protein Contact Networks, Long-range Interaction networks and Short-range Interaction networks, using complex networks analysis. The results show that Protein Contact Networks and Short-range Interaction networks regardless of their structural classes exhibit the ‘small-world’ property and Long-range Interaction networks indicate ‘scale-free’ behavior except all β protein networks. Our results further indicate that all Protein Contact Networks and Short-range Interaction networks are assortative type. While the Long-range Interaction networks of all β, α+β, α/βproteins are also of assortative type, some of them of all α proteins are of disassortative type. This indicates that the differences in structural class may assign specificity to the protein networks of long-range interaction.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125345465","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}

China's production of natural gas rose 12.3 percent year on year to 76.1 billion cubic meters in 2008 as the government promoted cleaner energy, and China consumed 67.3 billion cubic meters of gas in 2007, an annual increase of 19.9 percent. The dynamic GM(1,1) model of grey theory is used to forecast the natural gas consumption and production in China. In order to improve the forecast accuracy, the original GM(1, 1) models are improved by using Markov-chain. We analyze the data of the natural gas consumption and production from 1990 to 2007 in China, and forecast China’s natural gas consumption and production by this Grey-Markov forecasting model, which shows that the improved grey forecasting model is of more reliability and higher forecast accuracy than GM (1, 1).","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130883562","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 paper firstly uses wavelet de-noising for gait images. The text offers to use width descriptors as gait features and combines lower angle features. The Kernel-based fisher criterion and support vector machine is combined to classification and identification. The gait characteristic is extracted by KFDA, which can obtain the best projection direction and enhance the capacity of data classification. Then the support vector machine (SVM) models are trained by the decomposed feature vectors. The gaits are classified by the trained SVM models. The paper tries using wavelet kernel and obtains better result. This algorithm is applied to a data-set including thirty individuals. Extensive experimental results demonstrate that the proposed algorithm performs at an encouraging recognition rate of 91% and at a relatively lower computational cost.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125675409","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}

Consequently, the time that teachers’ contact with their students has been reduced accordingly, as a result, teachers have an urgent task to assist students’ autonomous English learning. In order to achieve this aim, teachers have to make efforts both in class and out of class. In fact, computer and network have already been incorporated in the college English teaching reform so as to make English learning more interesting, more individualized, more flexible, more varied, more independent and freer of the limitation of time and space. The author of this paper has conducted a teaching experiment in two classes to prove the feasibility of in-class and out-of-class cooperative learning in a computer-and network-assisted environment among non-English majors in the second-level colleges, and tries to probe into whether it can cultivate students’ awareness of autonomous learning.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128882946","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}

Cluster analysis is an important field of DM, which is to classify things in light of certain requirements and rules and plays very important role in mining the useful data. Combining with the fuzzy clustering and using the general mathematical system theory, the fuzzy clustering system model is setup. Fuzzy theory is applied to cluster analysis of DM and how to make use of the fuzzy relationship among samples to analyze the correlation is discussed. The main application steps of fuzzy clustering analysis in DM and the corresponding example are given. Through analysis and discussion, it is concluded that there are a few of different classification about machine learning modes. Comparing with the real records, the results by the fuzzy clustering are in keeping with the investigation in information extraction of machine learning.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124495184","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}
