Firstly, PCA algorithm was performed on training samples of each pattern class to calculate the optimal projection transformation matrices. A point that should be mentioned was that we used median vector rather than mean vector in total scatter matrix. The feature vectors of testing sample could be obtained by projecting it on the optimal projection transformation matrices. After that, reconstruction images phase was conducted to get the reconstruction image. Using the same procedure, the reconstruction image of testing image corresponding to each pattern class could be obtained. Finally, the error between reconstruction images and testing sample were calculated, respectively. The testing sample was belonging to the pattern class whose corresponding error was minimal. Experiments on Yale and ORL show that this approach works much better than traditional PCA.","PeriodicalId":315420,"journal":{"name":"2010 8th World Congress on Intelligent Control and Automation","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115524297","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 data is preprocessed by wavelet analysis to denoise and remove outliers. Fuzzy C-means clustering (FCM) is then used to identify the relation between efficiency of ironmaking and smelting intensity by using the processed data. Simulation based on data collected from No.7 blast furnace of Handan Steel show that the mean value of historical data (0.45) is not the stable thermal state of blast furnace. The system is more stable and has higher smelting intensity when silicon content is around 0.41, which shows that “low silica smelting practice” attempt in the steel industry can lower the energy consumption while keeping the smelting intensity and smooth production. It is proved that appropriate level of silicon content will lead to safe, smooth production with lower energy consumption and higher production.","PeriodicalId":315420,"journal":{"name":"2010 8th World Congress on Intelligent Control and Automation","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115583545","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 μ -synthesis robust PI controllers are solved.

To meet the system demand, the Independent System Operator (ISO) uses lump sum “uplift payments” to make generators follow its schedule. However, these uplift payments are opaque and difficult to hedge in terms of price signals. In addition, there are incentives for suppliers to bid other than their true costs. Untruthful bidding is undesirable, since in this case minimizing the total bid cost does not imply minimizing the total production cost, or maximizing the social welfare. As a result, the market may not be efficient. In this paper, system-wide redundant constraints on weighted generation levels are introduced to the day-ahead energy market to achieve equilibrium. With multipliers relaxing system demand constraints and redundant constraints serving as multipart prices, equilibrium can be achieved under the general condition that the optimal primal solution is among subproblem solutions for all units. Although incentive compatibility may not be achievable, the novel “local incentive compatibility” concept is introduced and quantified as the second best alternative to incentive compatibility.","PeriodicalId":315420,"journal":{"name":"2010 8th World Congress on Intelligent Control and Automation","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122511410","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}
