As a path to better understanding of the problem, the needs for exception handling are described as they arise at different times of the development cycle and from different disciplines. It is seen that a comprehensive solution is difficult but is essential. The details of stating requirements for exception handling are addressed and a methodology for verifying the effectiveness and completeness is described. Further research needs are discussed and the formation of a working group for a best practice or standard on the subject is suggested.","PeriodicalId":127732,"journal":{"name":"Third International Conference on Systems (icons 2008)","volume":"99 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116436508","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}

This field is relatively new; it focuses on the observation of life functions from a distance. Practically developing system works with an ECG sensor connected to mobile equipment, such as PDA/Embedded device, based on Microsoft Windows CE class operating system. The whole system is based on the architecture of .NET Compact Framework, and other products, such as SQL Server by Microsoft too. This work also deals with the communication of mobile equipment with sensors and with the server via Bluetooth, WiFi, and GPRS/EDGE. The mobile equipments are used primarily for measuring and processing of data from the sensors and their visualization as a graph. The data is also given to the server for further processing and the analysis of current health of the patients, due to small efficiency of the mobile equipment. The main task we deal with in the server part of application is receiving of the data via Web services and further processing, management and analysis of this data. For the analysis of received data and further evaluation of the electrocardiogram, there is a self-organizing neural network [1].","PeriodicalId":127732,"journal":{"name":"Third International Conference on Systems (icons 2008)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132993122","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}

Recent developments in CASE tool research have begun incorporating quite sophisticated natural language processing techniques to help generate class diagrams; however, considerable problems remain in the form of overlooked and/or excess classes. The difficulty stems largely from inherent ambiguity in written language; and a general lack of conciseness and completeness in requirements specifications. We argue that a more effective approach is to obtain classes from use cases, rather than directly from the specification. Our justification is that use cases describe specific functionalities of the system, and therefore the candidate objects involved in effecting those functionalities. To that end, we propose an algorithm to i) extract use case sentences from requirements, ii) validate functional specifications in each sentence of the use cases so that classes can be identified, and iii) reuse previously validated, domain- dependent use cases to supply missing functional specifications that may contain participating classes. Thereafter, classes are automatically obtained from these generated use cases. Problems arising from ambiguity in the written requirements are mitigated by imposing a small number of restrictions on the language that can be used for writing requirements, and the sentence structure of use cases is formalized.","PeriodicalId":127732,"journal":{"name":"Third International Conference on Systems (icons 2008)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133700674","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}
