Among various aspects, the problem of disconnection between business models, information architecture and detailed information models, also disconnection between functional architecture and information architecture are particularly focus of our work. We have developed UML profile for WIED (UPW) representing higher-level information aspects and demonstrated earlier its ability to address the problem of disconnection between business models and technical architecture besides integrating functional and information architectural aspects. In this paper we provide guidelines for mapping the UPW models to detailed information models. Resultantly, it enables UPW to form a bridge between higher-level information flows and detailed information design.","PeriodicalId":222828,"journal":{"name":"Proceedings of the IEEE Symposium on Emerging Technologies, 2005.","volume":"42 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120984110","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}

Conventionally, such platforms have very simple structures but have various associated limitations. One such problem is the generally imbalanced structure due to the placement of the elevation actuator on moving base. This design causes a lot of problems when platform is operated at high angular velocities. This paper, however, proposes a new design that is balanced in structure and very light due to placement of both actuators in the stationary base, hence finding its applications in high speed tracking problems. This thing in return has caused coupling between the two degrees of freedom. However, it is a kinematics problem and can be resolved easily in the control algorithm.","PeriodicalId":222828,"journal":{"name":"Proceedings of the IEEE Symposium on Emerging Technologies, 2005.","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127428286","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}

Explicit communication semantics are often considered essential for rich interaction between multi-agent systems. This paper describes the issues and trade-offs between OWL, (ontology Web language) and SL (semantic language) when used as semantic language for communication between agents. The comparison is done based on the factors of knowledge representation and expressive power. First part of the paper describes the expressiveness of communication between agents when SL is used as content language. Then the benefits of OWL are described before clarifying the pitfalls and issues in using it as content language for communication between agents. After the in-depth analysis of the two languages we emphasis that due to OWL compatibility and interoperability issues and lack of expressing modalities. OWL will not be a better option to be used as content language when compared with SL in agent communication language (ACL) message structure.","PeriodicalId":222828,"journal":{"name":"Proceedings of the IEEE Symposium on Emerging Technologies, 2005.","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122235062","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}

One of its objectives is to facilitate cataloguing of data in the form of files and directories on the physical storage media for easy and efficient retrieval. Over the years, even though storage capacities have increased drastically but no major architectural enhancement in the area of file systems have appeared. In this paper, we present our findings and an analysis of a study of the usage patterns of storage volumes in UNIX environment. This study is based only on those parameters that are directly related to the efficiency of a file system, i.e., file size, number of files in a directory, number of subdirectories in a directory, file name lengths and path lengths. The distribution of these parameters has been studied under different conditions of utilization. The results obtained are significantly important and provide considerable information for he design of a new file system.","PeriodicalId":222828,"journal":{"name":"Proceedings of the IEEE Symposium on Emerging Technologies, 2005.","volume":"264 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121819730","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}
