We investigated the SNPs that are not genotyped directly or indirectly by the current GWAS, and genomic regions associated with these unassayed SNPs. Through analysis of Hap Map CEU (European Caucasian), CHB (Han Chinese), JPT (Japanese) and YRI (Yoruba African) data, we identified the NGS SNP-free regions and the NGS common SNP-free regions (minor allele frequency (MAF) > = 0.05), We also calculated the number and the size of the NGS SNP-free regions and the NGS common SNP-free regions, where they have been reported so far, in different populations. In the analysis of NGS SNP-free regions and NGS common SNP-free regions, we found they have the character of independence. The distributions of the NGS SNP-free regions and NGS common SNP-free regions have the character of imbalance. The GW AS genotyping platforms could be further upgraded to include more SNPs to ensure true whole genome coverage.","PeriodicalId":302619,"journal":{"name":"2010 IEEE Fifth International Conference on Bio-Inspired Computing: Theories and Applications (BIC-TA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128236622","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 paper aims at the estimation of the nonlinear system with constraints, and a new method to deal with the equality constraints in the nonlinear system is proposed. The main idea is that we employ the projection approach in the quadrature Kalman filtering. Every quadrature point is projected on the constrained subspace, and the nonlinear transformation is more exact than before. The new method has better error performance than that of extended Kalman filter (EKF) with constraints. Target tracking example is presented to illustrate the effectiveness of the new method.","PeriodicalId":302619,"journal":{"name":"2010 IEEE Fifth International Conference on Bio-Inspired Computing: Theories and Applications (BIC-TA)","volume":"227 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128618699","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 result indicates that there are four centers of heat island in Chongqing city, mainly in industrial region, commercial and residential areas. The spatial distribution pattern of land use/cover affects the distributional pattern of the urban heat space. The following effective measures are proposed to solve the Chongqing heat island, including strengthening urban planning, increasing urban green coverage rate, controlling plant emissions and rational use of water resources.","PeriodicalId":302619,"journal":{"name":"2010 IEEE Fifth International Conference on Bio-Inspired Computing: Theories and Applications (BIC-TA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129733274","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 appends the probabilities to the existing features and then starts a new training procedure repeatedly to improve performance.

Agents dose not require any explicit and centralized control, instead using morphological information, which consists of genomes to coordinate their activities. This article describes a very simple genetic encoding and developmental system designed for self-organization of multicellular agents. The morphogenetic evolution system is inspired by gene expression (genetic encoding) and cellular differentiation.

Its basic idea is that: First of all, expressing the output of the Hammerstein nonlinear models as a regressive equation in all parameters based on the key term separation principle and separating key term from linear block and nonlinear block. Then, the unknown true outputs in the information vector are replaced with the outputs of an auxiliary model, the unknown internal variables and the unmeasured noise terms are replaced with the estimated internal variables and the estimated residuals, respectively. Accordingly, the problem of the nonlinear system identification is cast as function optimization problem over parameter space; a particle swarm optimization (PSO) algorithm is adopted to solve the optimization problem. In order to further enhance the precision and robust of identification, an improved particle swarm optimization (IPSO) algorithm is applied to search the parameter space to find the optimal estimation of the system parameters. Finally, the feasibility and efficiency of the presented algorithm are demonstrated using numerical simulations.","PeriodicalId":302619,"journal":{"name":"2010 IEEE Fifth International Conference on Bio-Inspired Computing: Theories and Applications (BIC-TA)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123937077","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}

Because mobile nodes have limited battery power, it is therefore very important to use energy in a MANET efficiently. In this paper, we provide an energy Entropy Multipath Routing optimization algorithm in MANET based on GA (EMRGA). The key idea of the protocol is to find the minimal node residual energy of each route in the process of selecting path by descending node residual energy. It can balance individual nodes battery power utilization and hence prolong the entire networks lifetime and energy variance. Experimental shows that the approach is efficient, promising performance advantage for multipath traffic engineering and evaluates the route stability in dynamic mobile networks.","PeriodicalId":302619,"journal":{"name":"2010 IEEE Fifth International Conference on Bio-Inspired Computing: Theories and Applications (BIC-TA)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123993673","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}

Before this technique can be put into practice, we must develop methods to manage the collected user session data.

We first collect user sessions from log files and construct a service profile of the application. Then, we build the relational matrix between these two fields. Finally, through concept analysis, a reduced user session set is produced. Experimental results show that our technique can significantly reduce the quantity of collected user session data while retaining service coverage of the application and enhancing the fault detection rate.
