Dividing the common observe space into numerous of small grids, the measurements containing uncertainties can be represented by their sampled probability density functions. By adding probability density of all measurements taken from one sensor grid by grid, we got the probability density matrix (PDM) of this sensor. Combining PDMs of all sensors together produce a joint PDM. Peaks in the joint PDM can be considered as estimated locations of targets. Theoretic analysis show that the computation cost is proportional to the product of the number of sensors and that of targets, and will not lead to combinatorial explosion. The presented method has a high precision and is suit for parallel processing. Simulation results verify the feasibility and validity of the proposed technique.","PeriodicalId":217369,"journal":{"name":"2009 Asia Pacific Conference on Postgraduate Research in Microelectronics & Electronics (PrimeAsia)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130936794","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}

Based on the interleaved boost converter with coupled inductors, a converter consisting of four interleaved boost converter cells is proposed in this paper. The boost converter cells can share the input current, so this prototype circuit can be designed to have small input current ripple. And when using this method, output voltage ripple can also be reduced. The operating principle is presented. The steady state performance of the boost converter is investigation by a saber simulation. A 2.5kW boost converter with four interleaved boost convert cells has been realized and successfully tested in the laboratory.

This paper studies this important problem and presents a novel approach called section-based tracking (SBT) that is based on the section information provided by the division of the object's weight image. This approach serves to eliminate fake extremal points and make the tracking process more robust. Besides, this paper proposes qualitative rules for section-based kernel design, which help create a better kernel within SBT framework. Experiments show that both the SBT method and the kernel design rules conduce to better performance in tracking process.","PeriodicalId":217369,"journal":{"name":"2009 Asia Pacific Conference on Postgraduate Research in Microelectronics & Electronics (PrimeAsia)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126168703","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}
