The decoupled control of the active and reactive power is crucial to the applications of the BDFM in WECS. The robust control strategy based on sliding mode theory is applied for the independent control of active and reactive power of the BDFM. The controller is designed through the Lyapunov stable theory to ensure the stability of controller and achieve the required control result. The effect of the proposed method is tested with the matlab/simulink software. Simulation results illustrate the good performance of the controller and proves the power control strategy's feasibility.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"32 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120850749","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}

To enhance the adaptability, the system learns direction relations between target and its shadow, automatically.

Saaty suggested that the consistency ratio (CR) should be less than or equal to 0.1. Some researchers argued that the cut-off rule should be a function of the matrix size. In this paper, by simulation analysis, we find that, as the matrix size increases, the percent of the matrices with acceptable consistency (CR les 0.1) decreases dramatically, however, on the other hand, there will be more and more contradictory judgements in these sufficiently consistent matrices. This paradox shows that it is impossible to find some proper critical values of CR for different matrix sizes. Thus we argue that Saaty's consistency test could be unreasonable.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127087113","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}

In this paper, we propose a practical key issuing scheme. User registers at a local registration authority in off-line manner, local registration authority signs and delivers authenticated userpsilas information to multiple PKGs in batch manner. The master key is generated by PKGs based on secure distributed key generation protocol, which solves the key escrow problem. The secure channel between the user and the PKGs are not needed by using blinding technique. The proposed scheme is more efficient than those of existing key issuing schemes and the security is proved under random oracle model.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127904645","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}

It can simultaneously detect five kinds of different toxic gases, namely, CO, SO2, H2S, Cl2 and NH3, by using of electrochemical gas sensor array. The electrochemical gas sensor only responds to the specific gas, and has good selectivity and linear output, so the electronic nose dispenses with the pattern recognition algorithm in measuring multi-type gases simultaneously, which greatly reduces the operation task of olfactory system and improves the detection accuracy and efficiency to meet the robotpsilas real-time requirement, and can be conveniently changed corresponding gas sensors based on the target gases. By virtue of the compact structure, simple mechanical interface and communication interface, not only can the bionic electronic nose be used as a standardized component for all types of robots to help them to accomplish works related to olfaction, but also as a portable electronic nose applied to detect toxic gas in many fields.","PeriodicalId":326534,"journal":{"name":"2008 ISECS International Colloquium on Computing, Communication, Control, and Management","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130441357","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 of the most important mining tasks is clustering. There already lots of clustering algorithms for data stream have been presented. Fuzzy cluster is an important clustering method. However, to the best of our knowledge, all the clustering algorithms are hard clustering methods, fuzzy clustering algorithm is presently not used directly for data streams. Fuzzy c-means (FCM) is a typical fuzzy clustering algorithm. In this paper, we extend FCM and propose a weighted fuzzy algorithm for clustering data stream.
