Based on a constructivist understanding of knowing, we have developed MailTack as a tool for Persistent Business Discussions combined with an Individual Knowledge Assessment. By helping the involved individuals in improving the effectiveness and efficiency of their asynchronous conversations we think that MailTack could contribute to make collaborative learning and asynchronous interactions (for cooperating, coaching, tutoring, etc.) more successful and attractive thus facilitating the dynamics of Communities of Practice and more generally of learning communities.","PeriodicalId":254550,"journal":{"name":"Proceedings. 13th International Workshop on Database and Expert Systems Applications","volume":"394 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124454849","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 motion of the object is represented by a trajectory, which can be constructed using the available electronic maps and the information about traffic patterns. However, the statistical information about traffic patterns may change due to accidents, extreme weather conditions, road work, etc. In this work, we present a model for updating the trajectories of moving objects when unexpected traffic conditions occur. Many sites provide up-to-date information about traffic conditions on major expressways. However, the unexpected traffic conditions may affect not only the vehicles on the expressways for which an on-line monitoring is provided, but may also have an effect on the streets near those expressways. We propose a model of this spill-over effect and we utilize it in the process of identifying the trajectories which are affected by the abnormal traffic.","PeriodicalId":254550,"journal":{"name":"Proceedings. 13th International Workshop on Database and Expert Systems Applications","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121679226","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}

APA are a universal and very flexible operational description concept for communicating automata. Their specification, analysis and verification is supported by the SH-verification tool (SHVT). The local state of each agent is structured in several components describing its knowledge of keys, its \"view\" of the protocol and the goals to be reached within the protocol. Communication is modeled by adding messages to and removing them from a shared state component network. Cryptography is modeled by symbolic functions with certain properties. In addition to the regular protocol agents an intruder is specified, which has no access to the agents' local states but to the network. The intruder may intercept messages and create new ones based on his initial knowledge and on what he can extract from intercepted messages. Violations of the security goals can be found by state space analysis performed by the SHVT. The method is demonstrated using the symmetric Needham-Schroeder protocol, and an attack is presented that does not involve compromised session keys. Our approach defers from others in that protocol specifications do not use implicit assumptions, thus protocol security does not depend on whether some implicit assumptions made are reasonable for a particular environment. Therefore, our protocol specifications explicitly provide relevant information for secure implementations.","PeriodicalId":254550,"journal":{"name":"Proceedings. 13th International Workshop on Database and Expert Systems Applications","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132747993","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}
