The placing problem of the tree-structured diagram satisfying certain given eumorphous conditions is called a tidy drawing problem. The eumorphous conditions of tree-structured diagrams, oriented to program diagrams, have been formulated by modifying the eumorphous conditions of trees. formalized eumorphous conditions and corresponding unformalized methods of placement on the integral lattice were developed by Ogura etal. (1992). In this paper, we introduce new eumorphous conditions on the Euclidian plane. We also formulate O(n)-time and O(n/sup 2/)-time practical algorithms to provide placements which satisfy new eumorphous conditions by modifying the former conditions on the integral lattice As a result, we have new relationships among the eurmorphous conditions.<<ETX>>","PeriodicalId":375808,"journal":{"name":"Proceedings of 1993 IEEE 17th International Computer Software and Applications Conference COMPSAC '93","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134377884","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}

Scheduling of dynamic divide-and-conquer computations on multicomputers 多机动态分治计算的调度

This paper presents a new scheduling strategy based on the observation that it may be possible to capture the near-term resource requirements of active tasks by expressions involving task parameters. Run-time evaluation of these expressions yields estimates of task behavior that are valid over a short, future interval of time. The heuristics proposed, which when used in conjunction with information supplied by profiling, can be used to annotate the source program with such expressions. Preliminary simulation results show that the use of near-future estimates in a dynamic scheduling strategy for divide-and-conquer algorithms consistently improves over traditional dynamic strategies. The performance of this strategy approaches that of the best-known deterministic strategy while incurring an overhead of the same order as other dynamic strategies.<<ETX>>","PeriodicalId":375808,"journal":{"name":"Proceedings of 1993 IEEE 17th International Computer Software and Applications Conference COMPSAC '93","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131126184","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}

Existing research into the use of the OO paradigm is heavily biased toward front-end problems: design, programming languages, and development environments. Lost in this has been support for maintenance of OO system, yet maintenance is 80% of the effort for successful software systems. This paper focuses on software tools that support and enhance the software maintenance effort for OO systems. As the industry matures in its use of OO concepts, systems will move along a spectrum of object-oriented-ness, from non-OO systems at one end to fully OO systems at the other. Each end of the spectrum has different maintenance and tools needs.<<ETX>>","PeriodicalId":375808,"journal":{"name":"Proceedings of 1993 IEEE 17th International Computer Software and Applications Conference COMPSAC '93","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130541287","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 paper suggests to use production models paired with software metrics that quantify key drivers of productivity. We also show capabilities of production models with two examples. Production models must be used with proper parameterization to be successful. This may mean a new look at which metrics are helpful for process assessment.<<ETX>>","PeriodicalId":375808,"journal":{"name":"Proceedings of 1993 IEEE 17th International Computer Software and Applications Conference COMPSAC '93","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115248837","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 system includes interactive browsers, editors, and databases to manipulate the object model we designed specifically for the software in home appliances. We apply the object model to an entity that represents the specifications of a home appliance product. In other words, we introduce product specification objects and component objects to represent the characteristics of software in home appliances. As all developers using Visual CASE can discuss the specifications on the same framework, misunderstandings and misconceptions of the specifications seldom occur.<<ETX>>","PeriodicalId":375808,"journal":{"name":"Proceedings of 1993 IEEE 17th International Computer Software and Applications Conference COMPSAC '93","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128320880","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}
