But due to many reasons, the captured finger-vein images are blurred and contain a lot of noise. In this paper, we propose a new method to enhance the contrast of the finger-vein image. It consists of three parts: wavelet denoising, contrast enhancement and binary image. At first, we perform stationary wavelet decomposition and transform the image into four frequency bands: low frequency band LL, middle frequency bands LH and HL, and high frequency band HH. To different frequency bands, we design different denoising method. Then we select a special sort of histogram template equalization method to enhance the contrast of the finger-vein image. Finally, we get the binary image using the OTSU method. Our experimental results in this paper show that the proposed method can properly enhance the contrast of the finger-vein image and gets good effect.","PeriodicalId":129691,"journal":{"name":"2010 Asia-Pacific Conference on Power Electronics and Design","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128175269","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 mathematical modeling on the quadrature error of quartz beam vibratory angular rate sensor was presented in this paper. The effects of quadarture error model to the sensor’s performance were analyzed based on the analysis of work principle and error induced by quadrature. And the correlation detection suppression method to the quadrature error on gyroscope performance was presented. Simulation of the system was also content. The results showed that mean square deviation of output signal was reduced by 54.52???, and the zero drift was suppressed.

In single-side heating situation, the narrow channel is divided into three zones, bubbles generating zone, growth zone and annihilation zone. The motion characteristics of bubbles in various stages are accompanied by the changes of three zones. The courses of bubbles generation, growth and departure are numerically simulated. All the calculation conducted takes the gravity, surface tension and wall adhesion into account. Found that surface tension is much more important than gravity in the process of boiling heat transfer. As the overheating increases, the departure diameter D of bubbles increases significantly. When the bubble diameter D is larger than 1.5mm, it will be influenced by the incoming flow. The existence of bubble bottom micro-layer accelerates the flow convection on the wall and increases the coefficient of heat transfer. The results of simulation have a good coherence with experimental datum.","PeriodicalId":129691,"journal":{"name":"2010 Asia-Pacific Conference on Power Electronics and Design","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122395740","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 strategy calculates the commands of positive and negative sequence currents using the equation principle of instantaneous power, and designs positive and negative sequence controllers to regulate the positive and negative sequence currents separately. By decoupling feed-forward and PI controller, this strategy can achieve good performance. The details of the strategy are given then. The phase of the unbalanced voltage is locked using phase locked loop (PLL). The positive and negative sequence currents are separated and picked up using notch filters, and controlled by decoupling feed-forward and PI controller. The results of the simulation verify the correctness of the proposed control strategy.","PeriodicalId":129691,"journal":{"name":"2010 Asia-Pacific Conference on Power Electronics and Design","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128584895","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}
