Because the TDNN is time-shift invariant, input patterns do not need to be aligned. Also, the TDNN uses temporal information in its mapping process. Experimental results show that a TDNN-based speaker identification outperforms a weighted-distance-measure-based speaker identification system that does not use temporal information.","PeriodicalId":260036,"journal":{"name":"1993 (25th) Southeastern Symposium on System Theory","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115669894","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}

M. Dawson et al. (1991) is redesigned. The controller exploits aspects of the dynamic model to provide a global uniform ultimately bounded (GUUB) stability result despite the presence of parametric uncertainty, joint flexibility, and mechanical actuator dynamics. The controller delivers the GUUB result for both the position and the velocity error. The redesign enables the final ball in which the link tracking error resides to be arbitrarily shrunk and the exponential rate at which the error approaches that ball to be increased by adjustment of the control gains.","PeriodicalId":260036,"journal":{"name":"1993 (25th) Southeastern Symposium on System Theory","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116454516","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 model is modified by adding another transmission line and a transformer to study the effect on reliability. A significant decrease in system down time is found when a transformer is added in parallel with the two existing ones, whereas adding another transmission line produces only a minimal decrease. A study has been conducted to determine whether it is economically feasible to add another transformer to increase the model system's reliability and decrease its down time. During a twenty-year period, it was found that the savings of energy, and the dollars associated with it, exceeds the costs of the additional transformer.","PeriodicalId":260036,"journal":{"name":"1993 (25th) Southeastern Symposium on System Theory","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122534377","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}

Several common image file formats are surveyed, highlighting the differing approaches to image compression. Fractal compression is examined in depth to reveal how an interactive approach to image compression is implemented. The performance of these techniques is compared for a variety of landscape images, considering such parameters as data reduction ratios and information loss.","PeriodicalId":260036,"journal":{"name":"1993 (25th) Southeastern Symposium on System Theory","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127285939","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}
