The interest in this language is evident from the numerous articles, texts and conferences which have addressed this language and its application within the real time embedded systems environment.\u0000 There have been research efforts directed to the use of Ada. These efforts have been conducted by a variety of individuals and organizations and have resulted in contributions to requirements and design methodologies as well as application areas. Thus, we are seeing several prototype implementations which illustrate the use of Ada in the software lifecycle.","PeriodicalId":321698,"journal":{"name":"ACM '82","volume":"16 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126011872","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 second stage then merges the sorted sub-files in parallel. It is shown that a given input file of size n can be sorted in 0(n) time using 0(log n) processors. The speed-up ratio, which is a measure of the effectiveness of parallel processing, with respect to the best sequential algorithm, is asymptotically proportional to log n, which is optimal in the number of processors used.","PeriodicalId":321698,"journal":{"name":"ACM '82","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125675435","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}

Originally developed for neuroanatomic studies (1), including investigations of cell topography and connectivity in brainstem nuclei, the system has become a versatile and powerful tool for three-dimensional analysis and display of a variety of types of image data, including studies of cardiac morphometry and 2-d gel electrophoresis. The system includes components for data input via video frame digitizer or digitizing tablet; graphical output through a high-resolution color graphics display or hardcopy plotter. Keys to the system's flexibility and power are a tree-structured data file system, in which line segments and shaded strips may be combined to form complex three-dimensional structures, and a disk-based virtual memory system which permits greater numerical accuracy and use of larger structures than would be otherwise possible with a 16-bit minicomputer.","PeriodicalId":321698,"journal":{"name":"ACM '82","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115860722","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}

Design review methodology addresses the need to test the system design as early as possible in the development cycle in order to avoid the potentially high expense of implementing an inadequate design. The methodology provides a way to examine the soundness of a design at various points of a system development prior to the actual building of a system. Design review can be considered a method of quality control of system design.\u0000 The methodology is an outgrowth of the structured walkthru concept, extended for on-line data base applications. The goal is to provide a perspective of the design from the point of view of meeting the specific requirements of the system and a balance between performance, flexibility, availability, and user function.","PeriodicalId":321698,"journal":{"name":"ACM '82","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121185055","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}
