These orbital perturbations can cause an early failure of the satellite. The solar and linear perturbations vary in their effect, for any given initial orbit, according to the day and hour of injection. In fact, the change of a fraction of an hour in injection time may cause a change in the satellite's lifetime of several months. So for effective planning of a satellite mission, these perturbations must be predicted.","PeriodicalId":297471,"journal":{"name":"AFIPS '66 (Fall)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1966-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130453286","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}

In addition, film is not reusable; consequently, when no permanent record is required, the use of film is extremely wasteful.","PeriodicalId":297471,"journal":{"name":"AFIPS '66 (Fall)","volume":"375 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1966-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134232903","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}

Newspapers are among those using computers in the production of type cast in lead. The staff of the Los Angeles Times, in collaboration with RCA Corporation, implemented a program for the RCA 301 to accept typewriter by-product paper tape at 1,000 characters per second, to justify and hyphenate lineage of variable font size to newspaper column width, and to produce paper tape output used to drive automatic hot lead linecasters. This set of programs has been supporting typesetting production requirements of over 300,000 lines per week for the past three years. Additional requirements, both present and future, demanded that a more universal use of the computer as a system with teleprocessing capability be implemented. The three principles underlying these requirements were:\u0000 1. Immediate recovery capability for operational failure and hardware demise.\u0000 2. Centralization of the computational function to allow remote news sources and printing facilities the use of the automatic typesetting resources.\u0000 3. Potential to expand the system allowing on-line graphic display terminals and time-sharing with large business applications.","PeriodicalId":297471,"journal":{"name":"AFIPS '66 (Fall)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1966-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126268045","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}

To accomplish these objectives, five typical organizations were selected, and each was dealt with in sufficient detail to allow subsequent predictions of cost and performance. Those chosen are applicable to random-access ferrite-core memories, and each design makes use of integrated circuitry to the extent permitted by the devices which presently may be procured in volume quantities.","PeriodicalId":297471,"journal":{"name":"AFIPS '66 (Fall)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1966-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124060873","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}

In particular, one area of critical importance for effective utilization of such a system is that of facilities for program debugging. In view of the important role they play, surprisingly little attention has been paid to the development of facilities to aid in the process of on-line program debugging. Furthermore, much of the work in this field has been described only in unpublished reports or passed on through the oral tradition, rather than in the published literature. The purpose of this paper is to survey the existing work in this area and discuss some possible extensions to it, with the dual goal of acquainting a wider public with currently-existing techniques and of stimulating further developments.","PeriodicalId":297471,"journal":{"name":"AFIPS '66 (Fall)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1966-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130690611","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}
