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}

The raw data generation is based on pulse to pulse synthesis in the time domain.

A fractal interpolation algorithm has been used to extract the fractal dimension from the natural terrain. The raw data simulation has been combined with the interferogram simulation to validate phase to height conversion and geocoding process.

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}

Quite often, there is little documentation describing a software system's architecture, especially in the case of legacy software systems. Thus techniques must be employed for recovering the architecture from the software's source code. Given the size and complexity of legacy systems, researchers have started exploring the use of automated techniques for architecture recovery. A technique that has shown promising results is clustering. Clusters that are obtained as a result of the clustering process represent sub-systems within a software system, but are nor easy to interpret until they are given appropriate names. In this paper, we present a cluster labeling scheme based on identifiers. As the clustering process proceeds, keywords are ranked using the inverse document frequency ranking scheme. Results of experiments conducted on a test system demonstrate that our labeling approach is effective. We also compare the clustering results of the complete algorithm and the weighted combined algorithm based on labels of the clusters produced by them during clustering.","PeriodicalId":222828,"journal":{"name":"Proceedings of the IEEE Symposium on Emerging Technologies, 2005.","volume":"445 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":"129239850","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}

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.
