Fast image matching method was proposed to conduct the quality inspection of micro-electromechanical systems (MEMS) chip. The advantages and disadvantages of gray projection based matching algorithm were analyzed. Then a compound projective feature matching method was put forward. VC based algorithm was given to achieve compound projective feature matching method. Compared with the traditional gray matching algorithm and the normalized cross-correlation algorithm, the ability to match and the match time of the proposed matching method were studied. Contrast with single direction of projection matching method, the matching accuracy of the given matching method was tested. Meanwhile the matching ability of proposed algorithm was test for a small angle rotation of image. Finally, the compound projection-based matching method was used to detect the quality of the MEMS chip, and the practicality of the proposed method in terms of time and accuracy were verified by experimental results.","PeriodicalId":275003,"journal":{"name":"2014 9th International Conference on Computer Science & Education","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134390511","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 incorporates a self-tuning estimator with Recursive Extended Least-Squares (RELS) method to approximate the unknown parameters of a discrete-time single-input single-output local water quality model. The proposed self-tuning scheme can be implemented on-line to automatically tune the parameters and derive the controller using an indirect self-tuning procedure. When deriving the controller, the closed-loop tracking performance in achieving the desired level of the particular water quality parameter at the measured node is the primary consideration. Additionally, the influence of noise and disturbance on the local water quality model is considered. The good performances of the set-point tracking and disturbance rejection in the simulation examples show the effectiveness and reliability of the designed self-tuning controller in improving the local quality of water through automated water treatment.","PeriodicalId":275003,"journal":{"name":"2014 9th International Conference on Computer Science & Education","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133296954","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}

However, the resource-limited and the inherent unreliability of wireless transmission makes the sensors in the IOT are vulnerable to many attacks. Hence, how to design an efficient and secure data aggregation mechanism becomes critical. In this paper, we present TBSDA-a trust-based secure data aggregation scheme. In TBSDA, secure data aggregation is achieved by behavior-detected trust evaluation and data assembling technique. The trust evaluation and data aggregation work synergistically. We analyze the performance of TBSDA in term of communication overhead and the sensitivity of malicious nodes that behavior abnormally, and compare with other clustering scheme.","PeriodicalId":275003,"journal":{"name":"2014 9th International Conference on Computer Science & Education","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123848827","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 solve the problem, more and more researchers implement the traditional clustering algorithms on the cloud computing platforms, especially for K-means clustering. But, few researchers pay attention to the K-means clustering structure, and most of researchers optimized the model of the cloud computing platform to raise the computing speed of K-means clustering. However the problem of instability caused by the random initial centers still exists. In this paper, we propose a K-means clustering algorithm with optimized initial centers based on data dimensional density. This method avoids the deficiency of the random initial centers and improves the stability of the K-means clustering. The experimental results show that the approach achieves a good performance on K-means, and improves the accuracy of K-means clustering on the test set.","PeriodicalId":275003,"journal":{"name":"2014 9th International Conference on Computer Science & Education","volume":"188 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124157690","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}
