To solve this problem, a multicarrier-based physical layer security scheme for the multicast systems is proposed, which takes the advantage of both space and frequency domain to form a relatively virtual multi-antenna system. Through subcarrier allocation the existence of null space in every subcarrier channel matrix is guaranteed, so that the artificial noise can be added to ensure a secure communication. Based on the Kuhn-Tucher condition, an optimal power allocation method is also proposed to maximize the security rates under the restriction of total power. Simulation results indicate that this scheme is unlimited by the amount of the sender antennas, and it improves the security rates by 2 bit/s/Hz than the average power allocation method.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115684371","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}

This consistency effect also was found in the facial expressional recognition in scenes. However, the underlying mechanisms of expressional recognition in scenes were not clear. In the present study, we addressed the question of whether emotional scenes influenced recognition of facial expression through top-down priming effect. In two experiments, emotional scenes and facial expressions were presented sequentially or simultaneously and participants were instructed to categorize facial expressions, ignoring scenes. Similar consistency effects and happy face advantage were observed which suggested emotional scenes automatically influenced expressional recognition through priming effect.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126734766","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 and for the first time, we introduce sliding mode control (SMC) laws to deal with power swing reduction problem in individual generators directly without linearizing their swing equations. The suggested control laws are implemented by static VAR compensators (or simply, the so-called SVC) attached to the output terminal of a generator. To improve steady-state and/or transient performances in power generation and operation of generators, we further consider adjusting the coefficients of switching function and the control gains. Numeric stimulation clearly shows that the suggested sliding mode control stabilization works well.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122613586","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}

First, the paper regards the third harmonic injection PWM (THIPWM) with 25% third harmonic as the minimum current harmonic PWM method, and proposes a simple algorithm to generate the third harmonic based on the three-phase fundamental voltage waves. Then the paper proposes a FVCI-PWM method, which ensures that the PWM waveform has the same fundamental component as the command sinusoidal voltage waveform without current closed-loop control. The simulation and experimental results upon the 60000rpm PMSM are carried out finally to verify the effectiveness of the proposed PWM method.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122103653","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}

When several nodes (more than two) need to exchange messages through one relay node, traditional PNC scheme can't deal with the addition of more than two EM waves. The paper proposes an enhanced physical-layer network coding scheme (EPNC) to solve this problem. Through this proposition more than two nodes can exchange messages in two time slots. A four node wireless network model is analyzed and compared with traditional data transmission (TDT) and PNC schemes in the paper. It is concluded that the proposed scheme achieves progress in throughput compared with PNC.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117272727","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 goal of point set registration is to match two sets of points and estimate the transformation parameter that maps one point set to the other. Among the many published registration methods, the recently proposed Coherent Point Drift (CPD) algorithm stands out for its accuracy. In this paper we show that by casting CPD in the Bayesian framework we can obtain even better results. In particular, in case of large translation amount, our proposed mathod has much less number of iterations than CPD without any loss of accuracy. Experimental results confirms the advantages of the proposed method and shows an overall speedup when compared with the CPD method.","PeriodicalId":415759,"journal":{"name":"2013 IEEE Third International Conference on Information Science and Technology (ICIST)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128455033","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}
