The basic justification for the design methodology presented an old precept from engineering design: a problem must be defined before it is solved. The result was a methodology which laid great stress on specifying the behavior of a system or a component in a system before producing the design. The simulation language, SODAS, was designed to allow a design to proceed in a hierarchical way, treating any system as a set of components, specifying the behavior of those components, then treating the components themselves as systems. By means of the SODAS language it was to be possible to evaluate the design at any stage in its development without excess effort.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1969-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130741193","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}

Once in medical school, almost all teaching is by demonstration, with a very small number of students per instructor.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1969-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128535462","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}

Insight into the performance of multiaccess computer systems can be gleaned from these analyses. In this paper emphasis is placed on communications considerations.

One such simulation program at Cornell Aeronautical Laboratory, Inc. constitutes an analytical representation of an automobile as it departs from the highway under various environmental conditions, especially under adverse ones where there is danger of collision with obstacles. As with most complex simulation programs where there are interactions among many components, the equations of motion, including the required restraints, become long and numerous. But foremost, the output data set in printed form is quite extensive and very difficult for the investigating engineer to completely comprehend. About thirty crowded pages of output are printed for a five second automobile test run.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1969-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115274344","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 degrees of freedom in the representation are such as to provide a rich variety of surfaces with convenient parameters for manipulation and constraint satisfaction. Historically this work began as an investigation of the properties of rational parametric cubics, a class of curves well-suited to the Harvard three-dimensional display. The desire to represent curvilinear surfaces in terms of these curves and an introduction to the Coons' surface formulation were sufficient to suggest the approach discussed here.","PeriodicalId":326625,"journal":{"name":"AFIPS '69 (Spring)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1969-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133516613","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}
