This paper introduces a novel read-out method for a master-slave RFID reader architecture, which improves the accuracy of RFID tag detection, localization, and reduces the cost and complexity of the system by using a full wireless technology. The master reader is generally fixed and the slave reader can be fixed or mobile. This architecture also dramatically improves reading distance and operation time of mobile RFID readers in smart spaces. Furthermore, workflows of few smart spaces shopping services are introduced using this architecture.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116910644","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}

Many fields including education and business can benefit from the visual collaboration. We already have many picture media sharing applications on the web, but the most natural media format organizing the information is the web page, but till now, there is no a very well-known application offering pure web page sharing without installing any plug-in or client software. In the paper we proposed an collaborative web page browse application based on AJAX and Comet technology, human action is transported to a collaborative server by additional AJAX process, audience browser's reaction is done by Comet data receiving. By filtering the URL and JavaScript code in the original web page, the collaborative server can convert the ordinary single-user oriented web page into multi-user collaborative web page without changing the media type of content like pictures. We use browser event hooking to make the change of display or user action available for the collaborative server, overriding of the mouse right button behavior make the operation more feasible than dull screen grabbing. Now time we are implementing the prototype of the application on several open-source projects.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116865814","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}

Previous studies of discovering semantic relationships are mainly based on the information extraction using manually annotated training set and predefined semantic relationship patterns. In this paper, we propose a new method to automatically discover the semantic relationships between two concepts in knowledgebase through text classifying and information filtering. The documents related to the two concepts in knowledgebase are at first classified into different taxonomies and the connecting terms capturing the semantic relationships between the two concepts are extracted. The experimental results show that our method has provided an efficient and effective way for the automatic discovering of semantic relationships for information management.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122390283","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 mean shift particle filter algorithm significantly improves the accuracy of the particle state estimation and reduces the necessary number of samples by using the current observations in sampling procedure to obtain a sample distribution. It also reduces the interference among multiple targets in close proximity by weighting samples according to the virtual hamming distances and interaction potentials. By arranging the state distributions of mobile targets, the proposed scheme can handle the multiple peaks in state estimation of mobile targets and improves the localization accuracy.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115788352","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 COTS devices used include several different vendors' models of the microsoft Pocket PC platform (also known as windows mobile professional or classic) running .NET compact framework, as well as a number of different models of Java enabled cell phones from nokia, siemens and sony-ericsson. The specific case study is with the Taxmaster4 Windows mobile product used with BMW automobiles as a driving log application. The paper concludes that many usability problems exist when using COTS products. These may to some extend be overcome by pragmatic design decisions, but it is necessary that the COTS products hardware platform and application programming interfaces should become better suited to support distributed user interfaces than is the case today. This includes better support for basic user interface elements as well as supporting Bluetooth and other wireless technologies more reliably. These issues should be addressed by the vendors and manufactures of these platforms, not the application programmers.","PeriodicalId":244239,"journal":{"name":"2008 Third International Conference on Pervasive Computing and Applications","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128440357","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}
