In order to relieve the difficulties of such a high dimension, this paper proposes the classification computation, which refers to a modified neural network: the neural network with weights optimized by particle swarm intelligence. The contemporary is placed on the combination of the non-linear feature extraction and such a classification method. 10-fold cross-validation experiments of each method are performed on five medical data sets. The results indicate not only the improvement of classification based on non-linear feature extraction, but also indicate the reduction of the number of features for classification.","PeriodicalId":387286,"journal":{"name":"2009 International Conference on Computational Science and Its Applications","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130742246","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}

We formulate algorithms to estimate RL and CIs as a continuous measure, based on the partial information of the ongoing process. By using the proposed method, RL and CIs can be estimated in real-time during process execution, so as to effectively control the process quality. Furthermore, it is feasible to generate early warnings based on the status of RL and CIs. We also provided experiments to compare the proposed method with existing approaches, which showed that the proposed method can detect the risks of the ongoing process more precisely and even earlier than existing approaches.","PeriodicalId":387286,"journal":{"name":"2009 International Conference on Computational Science and Its Applications","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131495807","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}

Fast Handovers for Proxy Mobile IPv6 (PFMIPv6) was studied by mipshop working group to reduce packet loss in PMIPv6. PFMIPv6 is fast handover extension of PMIPv6. PFMIPv6 handover latency is longer than PMIPv6, although it reduces packet loss in PMIPv6. In this paper, we propose Enhanced PFMIPv6 to reduce handover latency. In the proposed scheme, the Proxy Binding Update (PBU) message is sent to Local Mobility Agent, in advance, when new mobile access gateway (NMAG) receives the Handover Initiate (HI) message. The HI message includes necessary information to build PBU. We analyze the performance of EPFMIPv6 compared with PMIPv6 and PFMIPv6 mathematically.","PeriodicalId":387286,"journal":{"name":"2009 International Conference on Computational Science and Its Applications","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122181229","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}

As such, KETpic can also be used to generate surfaces. But because surfaces appear flat both on the screen and in printed form, shading is often used to emphasize their inherent three-dimensional nature. Unfortunately, this solution is no longer valid in KETpic, as it generates figures in black-and-white only. In this paper, we outline some techniques to yield line drawing pictures of surfaces by using plot data obtained from implicit functions of two variables. The paper discusses some theoretical issues regarding the use of the ImplicitPlot command for drawing surfaces and describes the implementation of our results by means of several illustrative examples. As the reader will see, we obtain very nice figures that can readily be embedded into our LATEX documents in order to yield educational materials as well as professional printouts of scientific documents.","PeriodicalId":387286,"journal":{"name":"2009 International Conference on Computational Science and Its Applications","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125113608","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}

An advantage of our approach over the general purpose machinery, which requires computation of the lower envelope of a set of halfplanes in three-dimensional space, lies in its relative simplicity. Besides, we point out that the unweighted Voronoi diagram for $n$ lines in the plane has a simple structure, and can be obtained in optimal $Theta(n^2)$ time and space.","PeriodicalId":387286,"journal":{"name":"2009 International Conference on Computational Science and Its Applications","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132093850","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 application presented allows the ¿nal user to study, in a more intuitive and enriched way, the outcomes of the molecular simulation, fostering a better comprehension of properties and mechanisms of the investigated molecular systems. The particular application chosen for the present study is the quantum mechanical atom-diatom reactive scattering program called ABC that carries out accurate calculations of the quantum S matrix elements to evaluate reaction probabilities as well as state-to-state integral and differential cross sections. The presented application is designed to minimize the knowledge required to the scientist in order to be able to execute on a given computational environment the simulation and the study of the molecular properties of complex systems, focusing their attention merely on the computational chemistry aspects of this activity.","PeriodicalId":387286,"journal":{"name":"2009 International Conference on Computational Science and Its Applications","volume":"206 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123276331","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}
