Therefore, this paper proposes an improved variable step PO (perturb and observe) and Global scanning method (VSPO&GS) to achieve the maximum power point tracking. This algorithm is guaranteed not to fall into local optimum, and to make the power oscillation less. This scheme is divided into two steps: 1) The improved variable step size PO is used to track the local optimum, 2) Then the global scanning is used to obtain the global optimum. Finally, the proposed algorithm is compared with a conventional fixed step size PO algorithm and validated for sudden changes in the irradiance. The simulation results show the proposed algorithm can accurately track the maximum power point (MPP) to avoid the power loss and improve the efficiency of PV array under partial shaded conditions.","PeriodicalId":6592,"journal":{"name":"2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics","volume":"52 1","pages":"382-386"},"PeriodicalIF":0.0,"publicationDate":"2015-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82714751","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 contrast to others, the proposed algorithm relies on merely two main aspects of Wikipedia, namely its articles titles and categories structure. The inner content of the articles of Wikipedia are not employed in our algorithm. We describe in this paper how to build a Term-Categories vector that defines how strong a term is associated to a Wikipedia concept. We also explain how this vector is employed when processing a text document to discover its main themes. We report the performance of our method by attempting to predict the most representative categories for a subset of Wikipedia articles.","PeriodicalId":6592,"journal":{"name":"2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics","volume":"96 1","pages":"452-455"},"PeriodicalIF":0.0,"publicationDate":"2015-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90842953","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}

And the small sensor faults will introduce modeling errors in the observation equations. Therefore, small faults need be detected successfully and quickly. A novel small fault detection (FD) method is proposed using the residuals generated by the unscented Kalman filter (UKF) for a fifth-order two-phase nonlinear motor. Firstly, the introduction of the UKF is given. Secondly, on the basis of the UKF, a fault detection scheme based on a local approach is proposed. The local approach is used to detect small faults from residuals obtained from the UKF. Besides, the comparison between local approach and generalized likelihood test approach is introduced to illustrate the effectiveness of the proposed method. Finally, the proposed fault detection method is applied to detect faults of a fifth-order two-phase nonlinear motor system.","PeriodicalId":6592,"journal":{"name":"2015 7th International Conference on Intelligent Human-Machine Systems and Cybernetics","volume":"20 1","pages":"304-307"},"PeriodicalIF":0.0,"publicationDate":"2015-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80588620","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}

Altruistic punishment is affirmed as one of solutions to elevate collaborative efforts, nonetheless, we can't ignore the inherent deficiency. Hence selfish punishment is put forward, the spatial public goods game (PGGs) with retaliation comprises of unconditional defectors, pure co operators, and retaliative co operators who retrieve part of payoffs which are created by their own from defectors except to contribute. This inhibits second-order free-riders and conquers the limitation of costly punishment. As is known to all selfishness is human nature. In human a typical human society, restitution against selfish behavior can be achieved through legal or arbitration proceedings, or perhaps ultra-legal means such as hiring gangsters, maybe the ways are resemblance to peer-punishment. This study invokes some interesting phenomenon like fault age and that all-C and all-D status change alternately. In addition to a dazzling visual graph of rock-paper-scissors type, the three strategies often appear as \"mantis catching cicada yellowbird behind\".

Comparing with non-controlled steering system, the simulation results show that the body lateral acceleration of the steer-by-wire system with Fuzzy-PID controller is smaller than that of non-controlled steering system, and the phase lag is also smaller, indicating that it has good tracking performance and better steering stability.
