Nonlinear model of half-car is constructed using the nonlinear dynamics of the electro hydraulic actuator and dynamic characteristics of the dampings and springs. The states of half car model are first predicted by Taylor series expansion and then a control law is introduced by minimizing the local differences between the predicted and desired states. The derived control law has an analytical form which is easy to apply and also it is not required online numerical computations in optimization. Performance of the nonlinear optimal controller is compared to the existing passive suspension system. The obtained results demonstrate that use of the proposed nonlinear optimal control technique improves the tradeoff between ride quality and suspension travel compared to the passive suspension system.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"22 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":"114861195","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 paper, we will discuss several existing resource discovery mechanisms that have been widely implemented in P2P networks. Thus, we are classifying the P2P systems based on their resource discovery mechanisms. Consequently, we will present taxonomy for P2P resource discovery as a hierarchy based on our classification. The classification is done for seek out generalities amongst resource discovery mechanisms. We also specifically highlight on issues related to challenges for providing the resource discovery mechanism to the P2P networks. Issues related to matrix for measuring the cost and benefit for choosing the right resource discovery mechanism for a P2P system will conclude the paper.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"14 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":"117031086","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, actuators such as stepping motors are driven by discrete input signals that generate motion in rotational steps. The results would therefore be different from the continuous path planned for the spherical robot. The spherical robot under study incorporates two stepping motors, which generate the rotation increments. This incremental rotation inputs cause error and deviate the robot from the desired path. The result of such discretization of actuating input is studied here. The robot path is simulated using the inverse kinematics relations. As the angular steps decrease with better resolution of motors, the motion approaches the path expected for continuous motion.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"103 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":"116413077","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 web has become a major vehicle in performing research and education related activities for researches and students. There is tremendous amount of information and knowledge existing on the web and waiting to be discovered, shared and utilized. We present an enterprise web framework regarding semantic web and mining in training institute, which can be used to not only improve the quality of web mining results but also enhances the functions and services and the interoperability of educational information systems and standards in the educational field. Mining the educational information on the web we are using new Semantic Web Mining technologies, such as Resource description Framework (RDF) and Web Ontology Language (OWL). For on line educational institute web site two important ontology’s would need to be built one ontology describing all the educational services provided, with the relation between each other and the other ontology describing the web site.

T-wave, as a part of ECG signal, is produced by ventricular repolarisation and its orientation usually corresponds with that of the QRS complex. Inverted T-wave in some leads can be a sign of abnormality. In this work we proposed a real-time algorithm to detect the polarity and symmetry of T-wave in those leads that contain positive R-peak. Abnormalities like myocardial ischaemia, can be identified by the proposed algorithm. This method is applied on 15 records of MIT-BIH of Physionet, in order to evaluate its performance. The real-time behavior of the algorithm makes it possible to be implemented on an ECG machine.","PeriodicalId":343870,"journal":{"name":"2009 Second International Conference on Computer and Electrical Engineering","volume":"1 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":"130041983","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}
