Based on the derived algorithm, a novel spatial-domain template with variable mask size is obtained. It can preserve the important information in digital images as it smooths. Experimental results and detailed case studies have shown that the derived template has advantages over the commonly adopted filtering masks. The quality of the resulting images is very good, even under strongly noise-corrupted conditions.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134289730","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}

One type of degraded IC is obtained experimentally by applying a low surge voltage. For the case of the op-amps, there exists a quantitative relation between the degradation of the IC predicted from the increasing off-set current and the correlation with output noise. The root-mean-square value of the noise is an effective index of degradation detection. A method based on a measurement of the minimum value of supply voltage necessary to maintain the correct logical operation is effective in detecting degraded TTLs. An automatic instrument for degradation detection of electronic cards is developed, and its effectiveness is verified.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133117269","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}

Because of the existence of a small singular perturbation parameter in the composite system, the construction of the full-order coordinating strategy is parametrically stiff and ill-conditioned. Instead, it might be possible to use the reduced-order coordination design to overcome the difficulties arising in the full-order coordination design. The authors propose a reduced-order procedure to construct the coordinating strategy for the coordinator and prove that the method produces the well-posed coordinating strategy.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"126 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128390615","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}
