Besides,the efficiency of our approach is manifested by the preliminary experiment.","PeriodicalId":422513,"journal":{"name":"2009 First International Workshop on Education Technology and Computer Science","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126916836","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 model is supposed to be strict in theory. The measure function is meticulously constructed. According to sequence in dividing the evaluating space, the rule of the incredible recognition is introduced. The evaluating result is reasonable. It is the practical model for synthetic evaluating on the stock market. The purpose is to provide quantitative point of view on the stock market to predict. Simplex technical index measure was used would be misleading to investors, the technical indicators should be used with each other. Only a number of technical indexes are applied could comprehensively reflect the characteristics of the stock market. Only investors who have a comprehensive understanding of the stock market's characteristics will be able to make more accurate investment decisions.","PeriodicalId":422513,"journal":{"name":"2009 First International Workshop on Education Technology and Computer Science","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115076936","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}

At the same time, keyword search over XML documents has been well studied because of its intuitive and friendly query interface. Consequently, XQuery Full-Text emerges as a full-text extension to XQuery to query both the structure and the text content of XML documents seamlessly. This paper proposes the extended twig pattern matching problem based on the semantics of 'ftcontains' expression in XQFT and develops a novel algorithm, XConquer, for matching an extended twig pattern. Our experimental results show that XConquer offers considerable performance benefits when compared with existing approach variation for this problem.","PeriodicalId":422513,"journal":{"name":"2009 First International Workshop on Education Technology and Computer Science","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115084764","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 original ways of data display can’t meet the practical needs. This paper analyses disadvantages of display and manipulate mode in operating state visualization. Based on balloon tips in windows operating system, the paper proposes to use balloon tips in DCS (Distributed Control system) visualization in power plants. The contents needed to be displayed in DCS are divided into data point, specific equipment and alarm point. Corresponding display mode is designed for the three objects. Electronic regulations are integrated as a functional module in balloon tips. The practical results show the proposed visualization technique is quick and flexible to operate. Moreover, it displays more information on the limited screen, reduces redundant window manipulation, and improves the human-computer interface of DCS and work efficiency.","PeriodicalId":422513,"journal":{"name":"2009 First International Workshop on Education Technology and Computer Science","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115492822","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}
