Many Internet auctions adopt the English auction The English auction is the mechanism to settle a successful bidder Conventional Internet auction systems are using one logical server called an auction server that is constructed with one or several servers. So, if simultaneous bids occur, the load of the auction server increases. Besides, when congestion at circumference of the auction server occurs, the response time will increase. We propose a new Internet auction method using decentralized selection servers which will reduce superfluous information derived from bidders. The proposed method tends to hold down the increase of the response time by lightening the processing load at an auction server and cutting down congestion around the auction server In order to evaluate the proposed method concisely, we assume a typical auction service and a network. We evaluate the proposed and the conventional methods by simulation experiments using a network simulator OPNET Modeler Consequently, it is shown that the proposed method is more scalable and can be deployed with smaller cost.","PeriodicalId":382808,"journal":{"name":"Proceedings 22nd International Conference on Distributed Computing Systems Workshops","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124322661","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 n+k/n method, a special mapping function is defined to map an intermediate set with n+k bits into a n bit information set. In the embedding process, the intermediate set is embedded into a cover image rather than embedding the information set. If the distance between features of the cover image and the bits of the intermediate set is less than that between the features and information bits, the better the cover image quality. According to the idea of the n+k/n method, a special case called the n+1/n method is proposed. In this method, the mapping function is an exclusive-or operation. When an information set is given, two sets which satisfy the mapping function can be obtained. That which has a smaller distance from feature bits is selected as an intermediate set. In the paper, it is proved that the maximum distance between the intermediate set and feature set is less than the average distance between the information set and the feature set. The reduction rate of feature modification for the n+1/n method will reach 25%, and the improving quality in the embedded cover image is more than 2.5 db.","PeriodicalId":382808,"journal":{"name":"Proceedings 22nd International Conference on Distributed Computing Systems Workshops","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125409923","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}

A large number of traditional Japanese fittings in a local city are redesigned by 3D computer graphics into CAD data and stored in the database servers distributed over JGN. Although each fitting data consists of more than several Mbytes size, the user can interactively retrieve the desired fittings and put them into the traditional Japanese interior to design more creative and original houses, hotels and other buildings in real-time. We present a prototype system using VRML and Java on networked CG workstations. The user can walk through the desired virtual space organized by various Japanese traditional fittings and interactively change those fittings by selecting from the database and replacing them by simple operations. As a result, our suggested system is useful not only for Japanese crafting but also for worldwide design industries.","PeriodicalId":382808,"journal":{"name":"Proceedings 22nd International Conference on Distributed Computing Systems Workshops","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114176357","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}
