First, the math model of a PMSM is introduced for the PMSM servo system, on which PIDNN controller with on-line learning, tracking and regulating ability is applied. This PIDNN controller is campared with the conventional PID controller, and single neural PID controller. The simulation results show that the control law of PIDNN yields excellent performance for both track following and real-time control in the PMSM servo system.","PeriodicalId":377991,"journal":{"name":"2010 5th International Conference on Computer Science & Education","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123082283","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 proposed model is to reconstruct a damaged original image by acting along the texture's direction and the vertical texture's direction which is determined by the texture's trend of the local image structure (This local image structure is measured by the so-called structure tensor). In order to guarantee better results, the intensity of the diffusion along the texture's direction should be much greater than that of the diffusion along the vertical texture's direction. The nonnegativity discretization method and optimized rotation invariance method is used to calculate the proposed model. It was shown in experiments that this model can get good results for inpainting the flow-like textures with line-like structures images that contain nicks or small broken areas.","PeriodicalId":377991,"journal":{"name":"2010 5th International Conference on Computer Science & Education","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116677882","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 requires that each tuple of a public released data table must be indistinguishable from at least other k − 1 tuples. Given a table, finding an optimal k-anonymous version is NP-hard in most previous recoding ”model”. Thus, designing an efficient algorithm to find high-quality k-anonymous version is still challenge, though k-anonymity is well-researched. In recent years, hierarchical partition is proposed and widely accepted. Viewing the given table as a multidimensional space, each hierarchical partition of the space is a multidimensional recoding under some special constraints. Previous works need huge computation to find optimal hierarchical partition, and efficient algorithms just find a reasonable hierarchical partition. In this paper, we show that optimal hierarchical partition for k-anonymity can be obtained within polynomial time when a fixed quasi-identifier is given. We then design a bottom-up algorithm using dynamic approach. Through theoretical analysis and experiments, we show that our algorithm finds better results than related works, and our algorithm runs significantly fast comparing with other optimal algorithms for hierarchical partition.","PeriodicalId":377991,"journal":{"name":"2010 5th International Conference on Computer Science & Education","volume":"36 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120885524","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}

Typical association rules consider only items enumerated in transactions. Such rules are referred to as positive association rules. Negative association rules also consider the same items, but in addition consider negated items (i.e. absent from transactions). Negative association rules are useful in market-basket analysis to identify products that conflict with each other or products that complement each other. They are also very useful for constructing associative classifiers. In this paper, we propose an algorithm that mines positive and negative association rules without adding any additional measure and extra database scans.","PeriodicalId":377991,"journal":{"name":"2010 5th International Conference on Computer Science & Education","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125833835","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 many cases, the significance of data item in streams decays with age: this item perhaps conveys critical information first, but, as time goes by, it gets less and less important until it eventually becomes useless. This characteristic is termed amnesic. Random Sampling is often used in construction of synopsis for streaming data. This paper proposed a Weighted Random Sampling based Hierarchical Amnesic Synopses which includes the amnesic characteristic of data stream in the generation of synopsis. The construction methods for weighted random sampling with and without replacement are discussed. We experimentally evaluate the proposed synopsis structure.","PeriodicalId":377991,"journal":{"name":"2010 5th International Conference on Computer Science & Education","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123505715","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}
