No attempt is made to provide an exhaustive survey, but rather to convey enough of the basic concepts and techniques of proving programs so that the interested reader can pursue specific interests on his own. Three fundamental aspects of program proving are described. The first is a general view of basic goals and objectives. The second is an introduction to the basic techniques of proving programs by inductive assertions. The third addresses applying these techniques in practice.","PeriodicalId":379505,"journal":{"name":"ACM '76","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115293902","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 describes how the capabilities and resources of one such system, normally used by faculty, students, and staff in a university environment, are being introduced and incorporated into a non-academic professional planning application. As a case in point, we present a plan to integrate the resources, talents, and needs of small size city and county planning departments with the facilities and expertise of information specialists based on a nearby university campus. The stated goals, the resources, the methodologies, the difficulties, and the successes are presented. Also discussed is the concept of “technology brokers”—people whose function is to bridge the communications gap that is often present between technology developers and potential users.","PeriodicalId":379505,"journal":{"name":"ACM '76","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1976-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121258996","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}
