The development of the Domestic Waterways Communication System from concept to fruition under MARAD leadership is discussed in the historical and geographical context of the two separate regions served, the Great Lakes and the navigable western rivers. The progress of the communication system to date is presented together with projections of the nature network. The Leverage Factor is developed to assess the efficacy of MARAD participation in this project and is evaluated for both the Great Lakes and Inland Waterways subsystems. The application of this concept as a generally useful means of selecting projects for future Federal participation is discussed.","PeriodicalId":105804,"journal":{"name":"27th IEEE Vehicular Technology Conference","volume":"154 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1977-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132277109","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 signaling function may be accomplished on a dedicated signaling channel or may be distributed over all of the communications channels. A summary of the considerations involved in specifying this system characteristic is presented. It is concluded that the dedicated signaling channel results in a fixed partition between signaling and talking capacity. If the loading of a common signaling channel would be sufficiently light so that it does not limit the talking capacity of the system, then probably the signaling function can also be distributed on the talking channels, still providing all necessary functions. With distributed signaling, the partitioning of capacity between signaling and talking can adapt to the traffic presented.","PeriodicalId":105804,"journal":{"name":"27th IEEE Vehicular Technology Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1977-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133868748","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 operating mechanism of a newly-developed magnetic pulse width modulator and its functions are analyzed. Using them to the best advantage has made it possible to integrate the principal functions for the chopper control, whereby a high degree of simplification of the control system has been attained. The excellent stability of the modulator to electrical noise signals, unavoidable to electric vehicles, is noteworthy. Applications of the technique to battery-operated locomotives and battery-operated fork-lift trucks are also mentioned.","PeriodicalId":105804,"journal":{"name":"27th IEEE Vehicular Technology Conference","volume":"362 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1977-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133781097","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}

It is manually operated and will soon be channel limited in London. Forecasts indicate a need for greatly increased capacity to cater for growth before further bandwidth is likely to be made available. Tests demonstrate that 12½ kHz spaced channels could be used, and traffic statistics show that over half of the used \"air time\" is taken up by operation and switching procedures. This paper proposes a new type of automatic system, using 12½ kHz spaced channels, in which all call set-up procedures are conducted by fast data transmission over a common channel. The traffic channels are thereby used for successful calls only and the capacity would be more than quadrupled; additional advantages are that the base stations would be used much more effectively, hence yielding a minimum-cost solution.","PeriodicalId":105804,"journal":{"name":"27th IEEE Vehicular Technology Conference","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1977-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128180436","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}

Talk channels are not assigned until the mobile has answered, and dialed dlgits from the mobile are stored before transmission. The signalllng 'handshakes' between the base and mobile equipment are described together with numbering, coding, synchronization and modulation schemes.
