The emphasis is on understanding the potentials and problems of using expert systems that are time constrained. The expert system has evolved as a competent method of solving relatively complex problems. The bulk of successful approaches, however, seek to determine cause, or conversely consequence, through the manipulation of a mass of knowledge. The \"expert\" consists of a set of decision rules that represent the sum judgment of a human Unfortunately, the underwater automation encountering a hazard miles from home can not seek a time consuming diagnosis. It must establish an optimal response when presented with an unexpected event that is often ill defined. Little emphasis has been placed on expert systems that deal with time explicitly. The untethered vehicle, however, must constantly react to external and internal events, must perform high speed data acquisition, and must provide control under very severe time constraints. A solution to this problem will permit intelligent systems to achieve much in the ocean. This paper describes some of the problems and approaches associated with applying time constrained expert system technology to guide an autonomous vehicle relaibly through its mission goals.","PeriodicalId":137921,"journal":{"name":"Proceedings OCEANS '83","volume":"42 5-6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120919417","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 data explosion has resulted in the creation of computerized archives for oceanographic data and an inability on the part of the individual researcher to keep abreast of developments in the field through literature sources as has been the practice in the past. This study was undertaken to sample 1000 users of marine pollution data and determine their attitudes and biases regarding the success or failure of present archiving activities. In addition, the questionnaire asked the respondents to express their preference for an \"ideal\" interactive system through which they could access data contained within National Oceanographic Data Center (NODC) files. Of the 1000 questionnaires mailed, 225 were returned. Answers to the questions posed in the sampling instrument were coded into numerical form and subjected to Chi-squared analysis in order to ascertain whether or not a given agency, position, or familiarity with computer systems had an influence on how the user regarded the value of the present system used by NODC. The results showed that more respondents still preferred hard copy sources (peer review publications, etc.) for their data. However, regardless of the attitudes revealed by the questionnaires, 90% of those responding agreed with the need for such archiving activities and 95% saw their interaction with such computerized data bases increasing over the next decade. The ideal computer system, as revealed by the respondent preferences, consisted of an interactive terminal with graphics capabilities which could access NODC data banks directly, via a buffer file. Based upon these results, recommendations were made to NODC regarding ways in which their operations might be made more compatible with the needs of the oceanographic research community.","PeriodicalId":137921,"journal":{"name":"Proceedings OCEANS '83","volume":"10 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":"114625499","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}

Gibson","doi":"10.1109/OCEANS.1983.1152144","DOIUrl":"https://doi.org/10.1109/OCEANS.1983.1152144","url":null,"abstract":"The subject of mooring lines encompasses a broad spectrum of service requirements (water depths, sea states, tensile loadings, and useful service lives) and a wide variety of candidate mooring members (chain, wire rope, synthetic fiber rope, electromechanical cables, or combinations of these elements). For some systems, a suitable mooring line may have a breaking strength of only a few hundred pounds, a length of up to 20,000 feet, and an operational life measured in weeks. In other cases, a mooring line must have a breaking strength of several million pounds, a length of just a few thousand feet, and an operational life measured in decades. A highly elastic mooring line may be required where large amplitude system motions must be accommodated, while an inelastic mooring line may be needed if it is necessary to assure accurate system positioning. Some systems may require that the mooring line survive prolonged cyclic tensile loading, while other systems may be dependent upon the ability of the mooring line to survive repeated bending over sheaves or saddles. To meet these diverse operational requirements, system designers must choose from among a variety of mooring members, each of which has a unique combination of strength, size, weight, elasticity, corrosion resistance, abrasion resistance, and ability to withstand extensive cyclic tension loading or cyclic bending. In nearly all cases, some compromise is required because of conflicting system requirements. This paper discusses some of the important considerations in the selection of a suitable mooring line, reviews certain mooring line characteristics, and describes laboratory testing methods for assessing the suitability of candidate mooring members for specific applications.","PeriodicalId":137921,"journal":{"name":"Proceedings OCEANS '83","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":"114698141","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}
