As the digital computer became more prominent, it was often used to cross check, to set up, and to solve problems run on the analog computer. Many digital codes were developed to complement, check out, and even replace the analog computer. Codes such as DAS, MIDAS, PARTNER, DYSAC, MIMIC, DSL/90, and others came into wide use, and some of the reasons for their development have been ably reviewed by Brennan and Linebarger and later by Clancy and Fineberg.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"553 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123381373","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}

Considerable experience was gained from The Boeing Huntsville Simulation Center (BHSC) where several generations of hybrid systems were evolved. Since these systems were highly successful both from an economic as well as scientific point of view, it seemed reasonable to pattern the Vertol Facility as much as possible after the Huntsville Facility. This had several immediate benefits. First, the specialized software packages would be compatible. Second, experienced personnel could be transplanted without dropping back on the learning curve. Third, future developments in systems and applications could be jointly undertaken, thereby avoiding duplication of tasks and saving The Boeing Company money.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132033958","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 in its inception was used to develop research programs and time-sharing software for use by the medical community in the Salt Lake City area. As a result, a software and hardware system called MEDLAB has been developed. Using this system, research programs were developed for cardiovascular studies. It soon became apparent that the programs which were being developed could also be used in a clinical environment.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114421101","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}

You alert the digital computer through your remote display. The digital computer recovers from its permanent files the data and source files associated with your run. These files include a description of your problem in equation format, a description of your problem in block diagram format as mechanized on the analog computer, the source hybrid problem, and data decks. After logging on the system, a complete set of hybrid software is available to you. You may run your program all digital using the equation input and the analog mechanization input to verify proper analog implementation of your equations. Using the outputs of the digital simulation ranges of variables may be determined for automatic scaling. The digitally simulated analog mechanization can be used for a patchboard and equipment verification of the actual analog connectives. Static checks may also be generated. Using the outputs of your digital simulation, you can test the various transfer blocks synthesized on the analog computer in a dynamic mode.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128408861","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 management and retrieval system should be oriented to providing its services in a simple and straightforward way to application programs written in a high-level language, such as PL/1 or COBOL. 2. The data base should be compact. Its second-generation predecessor was a pair of files occupying together some 35 reels of magnetic tape; but the new data base, which would need to meet significantly expanded data requirements, was to fit onto a single IBM 2321 data cell drive (capacity about 390 million bytes). 3. It should be possible to design, program, and implement the system with a configuration of machines and personnel commensurate with the anticipated benefits. 4. Provision should be made for storage, retrieval, and maintenance of data elements with widely varying space requirements. Well over half of our policies have no claims at all, but a few policies for very large companies acquire claims in the thousands. 5. Both sequential and direct accessing, in a variety of combinations, should be feasible, in order to accommodate file-scanning applications, efficient updating, and an open-ended variety of inquiry and reporting applications. 6. Retrieval should be swift enough to maintain rapid response to inquiries coming from several dozen remote inquiry terminals. 7. A very high level of data integrity must be maintained, with protection inplemented in at least three ways: detection of improper attempts to alter the contents of the data base; prevention of incorrect updating; and recovery from data, program, or machine failures in a minimum of elapsed time and with a high level of justified confidence in the restored version of the data base. 8. Both the data base structures and its management system should be flexible enough to permit new and unforeseen data requirements to be accommodated in the future with a minimum of disturbance to either operational application programs or the data base management system itself.","PeriodicalId":294588,"journal":{"name":"Proceedings of the December 9-11, 1968, fall joint computer conference, part I","volume":"271 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122703993","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}
