Because the grinding process is a complex system with big sluggishness, long time lag, serious non-linearity and time-varying, so only applying PID control can not make the ore grinding and grading process in the best state of control. There fore Intelligent PID control is applied to simple loop, and series intelligent PID control and fuzzy control strategy applied to complicated loop. The ore-feeding flow control loop, ore-feeding water control loop, ore-discharge water control loop, water level of pump pond control loop, pump pond concentration series control loop and inlet pressure of the water cyclone control loop are designed. By all these control strategies and control loops, intelligent control of the grinding machine is realized.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128854017","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}

Firstly, the images are divided into non-overlapping rectangular blocks with rows and columns of the ratio of 4∶3. Then, the algorithm, according to the statistical analysis, will determine whether each block is the prospect or not and end with the removal of isolated blocks by a smoothing filter. Experimental results show that the proposed algorithm has the advantages of time-saving and self-adaptability in dealing with different quality and shape of fingerprint images in comparison with the baseline.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121432213","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}

Theoretical comparison of IA and GA is first made. Then experimental comparison of the two algorithms is given by using them to perform the parameter optimization task for color recognition of license plates. For plate color recognition algorithm, color features are extracted in the HSV (hue, saturation, and value) color space and weighted fusion of the fuzzy maps on three components is utilized to perform color recognition. To improve the adaptability of recognition algorithm, weights of color feature components and thresholds of classification functions are optimized by immune and genetic algorithms respectively. Comparison experiments were conducted on three data sets. And the experimental results show that the immune-based approach achieves higher accuracy and smaller mean square deviation. From the theoretical and experimental comparisons, it is shown that many immune mechanisms, such as clonal explosion, immune supplementation, concentration adjustment, etc. can be used to solve the parameter optimization problem effectively and efficiently.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":"44 11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116101014","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 methodology, an evaluation model with software test characteristics (elementary set) and domain characteristics (extended set) is described; in order to weaken the uncertainty of subjective and objective, the rough set theory is applied to gain the attributes weights, and the gray analysis method is introduced to remedy the incomplete and inadequate information. The method is useful to assess characteristics, sub-characteristics and attribute that influence the domain specific software product quality qualitative and quantitative.

This paper proposes a novel mixed FRLS (MFRLS) algorithm for solving the problem. It dynamically makes a multiobjective cost function by weighting the local estimation and global estimation on the membership feature of the sampling point at each updating instant. Then the mixed co-variance matrix of the local and global estimation is deduced by solving the multiobjective optimization problem. Based on the mixed co-variance matrix, a set of MFRLS formula is obtained by further analytical deduction. The simulation experiments on a time-varying nonlinear model have proved the advantages of MFRLS.","PeriodicalId":142910,"journal":{"name":"2010 IEEE International Conference on Progress in Informatics and Computing","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115859507","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}
