Furthermore, transient and permanent faults could also occur during operation due to the sensitivity. Thus, defect and fault tolerance techniques are urgently needed. In this paper, we propose a concept of diversity mapping and three corresponding algorithms for defect-tolerance logic mapping in nanoelectronic crossbar. As the results show, our algorithms can achieve several or ten times higher logic mapping success rates compared to the best recently published technique over a set of samples with various problem sizes, especially superior in large scale problems. What's more, our algorithms can offer a set of different mapping schemes as by-products which we can utilize for accelerating online self-repair from the faults.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"9 1","pages":"149-154"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75274895","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 EMD-CT decomposition consists of three stages: the EMD stage, the Laplacian pyramid stage, and the multidirection analysis stage. As a result, the proposed EMD-CT shares high adaptivity of the EMD while owning multidirection analysis of the CT. For image fusion, fusion rules are applied on the EMD-CT representations of input images to produce a composite representation. The fused image is obtained by inversely transforming the composite EMD-CT representation. Experimental results show that the proposed fusion algorithm is more effective than fusion algorithms based on individual EMD or CT, and produces high fusion quality, especially for images with rich directional features such as edges and contours.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"79 1","pages":"577-582"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74051407","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}

We then discuss two cases for which Granger causality is zero but there exists real causality between two time series.
