The QIPSO algorithm makes use of a quadratic crossover operator to maintain the level of diversity in the swarm population, thereby maintaining a good balance between the exploration and exploitation phenomena and preventing premature convergence. We have compared it with Basic Particle Swarm Optimization (BPSO) and another diversity guided PSO called ARPSO. The numerical results show that QIPSO outperforms the other two algorithms in all the seventeen cases taken in this study.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132651864","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, existing methods of detecting boundary between pupil and iris, which is the first task in any iris-based biometric identification methods are computationally expensive. Further, existing methods are not able to detect pupil boundary accurately and hence leading to errors in identification process. In this paper, we address these two problems and propose a technique to detect pupil boundary efficiently and accurately. We propose scaling and power transform followed by edge detection and circle finding. Scaling reduces the search space significantly and power transform is helpful for image thresholding. Experiments on CASIA iris database reveal that with the proposed approach, we able to detect pupil almost 100% accurately.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125408069","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}

Thus, a complete access control must provide a flexible administration model to manage delegation. Unfortunately, to our best knowledge, there is no complete model for describing all delegation requirements for role-based access control. Therefore, proposed models are often extended to consider new delegation characteristics, which is a complex task to manage and necessitate the redefinition of these models. In this paper we describe a new delegation approach for extended role-based access control models. We show that our approach is flexible and is sufficient to manage all delegation requirements.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123173855","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}

One major difficulty in identifying these gene subsets is the availability of only a few samples compared to the number of genes in the samples. Here we treat this problem as a Multi-objective optimization problem of minimizing the gene subset size and minimizing the number of misclassified samples. We present a new elitist non-dominated sorting-based genetic algorithm (NSGA) called memetic- NSGA which uses the concept of memes. Memes are a group of genes which have a particular functionality at the phenotype level. We have chosen a 50 gene Leukemia dataset to evaluate our algorithm. A comparative study between Memetic-NSGA and another non-dominated sorting genetic algorithm, called NSGA-II, is presented. Memetic-NSGA is found to perform better in terms of execution time and gene-subset length identified.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126744538","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}

After that an adaptive controller will be proposed for controlling chaos in this system. This controller is based on model reference adaptive system (MRAS) method for a linearized system with delay.

The controller decouples the setpoint response from the load response and shows a stable response for a Transmission Control Protocol(TCP) flow dynamics, which is highly oscillatory or unstable under practical conditions. The proposed control scheme enables to track the desired buffer level successfully and reject any load disturbances such as unresponsive traffic flows efficiently. The controller parameters are estimated by the use of standard forms of closed loop system response. Network simulator (ns-2) based simulation results show improved performances of the proposed controller compared to that of some popular schemes like Random Early Detection(RED), Proportional and Integral(PI), Linear Quadratic Regulator(LQR) etc.","PeriodicalId":185608,"journal":{"name":"15th International Conference on Advanced Computing and Communications (ADCOM 2007)","volume":"418 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131578631","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}
