For dynamic modeling, the Euler-Language approach is selected to model flexible joint manipulator. Since lightweight materials are employed in the construction of manipulator, the assumption that negligible link deformation no longer applies. A nonlinear passivity-based control method for rigid flexible joint as well as flexible link is proposed here. The main idea of Passivity Based Controller (PBC) is to use energy state of a system to provide stabilization. The PBC is developed to achieve two goals: set point regulation and trajectory tracking. The controller brings the end point from unstable position to a certain stable position. Beside that, the controller are developed to control the position of there end-point in such a way that it tracks the desired trajectory which are tested by simulations.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122364484","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}

Blog classification using machine learning techniques is a key method towards doing it. We have devised a machine learning algorithm where features are created from individual sentences in the body of a blog by taking one word at a time. Weights are assigned to the features based on the strength of their predictive capabilities for illegitimate/legitimate determination. The predictive capabilities are estimated by the frequency of occurrence of the feature in illegitimate/legitimate collections. During classification, total illegitimate and legitimate evidence in the blog is obtained by summing up the weights of extracted features of each class and the message is classified into whichever class accumulates the greater sum. We compared the algorithm against the popular Naive Bayes algorithm and found its performance does not deteriorate in the least than that of Naive Bayes algorithm both in terms of catching blog spam and for reducing false positives.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122543598","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 overall receiver algorithm is divided into two parts: one to be implemented on an FPGA and the other on a DSP processor. A new distributed arithmetic based architecture for implementing a Sampling Rate Converter is also proposed. The main advantage of this architecture is that it does not employ any MAC unit, whose operational speed is, generally, a bottleneck for high filter throughput. Instead, it makes extensive use of LUTs and hence is ideally suited for FPGA implementation. The main design goals in this work were to maintain low system complexity and reduce power consumption and chip area requirements.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129360324","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 particular, one must deal with diverse local mechanisms, support dynamic creation of services, and enable dynamic creation of trust domains. As Grid services are adopted and applied widely, as definition of an organizational boundary fade away in support of virtual organizations, as virtual organizations continue to evolve to support intermediaries such as firewalls, load balancers, and messaging hubs, and as awareness of the threats organizations face becomes more well understood, the need for a security model within Grid services grows clear. This paper reflects the challenges and requirements we have identified in a Grid environment. Based on those requirements, the proposed security architecture, by extending and leveraging (rather than replacing) existing security technology and assets, will enable businesses and organizations to more rapidly develop secure, interoperable Grid services. Because of the important role of message in Grid services, we limit our scope to message level security when developing our security model.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"230 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126798243","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}
