To overcome the limitation of RVM with single kernel, a multi-scale RVM classification method based on intelligent optimization is proposed.

No channel state information (CSI) is available and even unitary space-time signals fail to operate. We give an effective method which applies MST-SB-TC as an alternative to the original multilevel space-time modulation and present an effective multilevel space-time (UST) signal-based BCJR-like maximum a posteriori (MAP) decoding algorithm, which makes full use of the channel characteristics when calculating the branch metrics. With iterative decoding and/or multiple receive antennas, it can further improve the system performance, which helps to give an acceptable bit error rate.","PeriodicalId":164945,"journal":{"name":"2012 International Conference on Systems and Informatics (ICSAI2012)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134414567","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}

Therefore it is important to model the characteristics of customers in DR, and this paper proposes customer information as registration and participation information of DR which are some indices to evaluate customer response such as DR magnitude, duration, frequency and marginal cost, and the customer response characteristics are modeled from this aggregated information. This paper also introduces a new concept of virtual generation resources with their marginal cost calculated in the same form as the conventional generation marginal cost according to customer information. Finally, some constraints of DR are manipulated and expressed using the information modeled in this paper with various status flags, and the optimal scheduling combined with generation and DR is proposed by minimizing the system operation cost including generation and DR cost, with the generation and DR constraints developed in this paper.","PeriodicalId":164945,"journal":{"name":"2012 International Conference on Systems and Informatics (ICSAI2012)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131197626","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 proposed governor used a fuzzy self-tuning proportion-integral-derivative structure controller that can provide variable gain strategies to account for nonlinearities in the system.

To address this problem, a novel method basing on bipartite graph matching is proposed in this paper. On the basis of the extraction of image features, we define a cost function according to the bipartite graph theory and minimize it by using the optimization technique to obtain an optimal map. Then, we calculate the mahalanobis distance to eliminate the mismatched points, since it takes into account the distribution of matched points. Finally, we apply the measure of coefficient of variation to evaluate the discrete degree and rerank the retrieved images.
