The wire specimens are exposed to PWM-VSC waveforms. After partial discharge erosion (PD) on enamel wire coatings, the surface roughness is measured by using image-tod software. In all investigations, the images used, are captured by using scanning electron microscope (SEM). The experimental results revealed that the surface erosion in the specimens without nanofiller is considerably greater compared to the specimens with ~1%, by wt, nanofillers. The statistical analysis, using Weibull distribution of dielectric strength data, show that the value of the shape parameter increases tremendously, which indicates that the coatings with nanofillers becomes more homogeneous and exhibits fewer defects.","PeriodicalId":291800,"journal":{"name":"2007 International Conference on Electrical Engineering","volume":"13 9","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132511444","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}

A diesel generator is added to ensure continuous power supply and to take care of intermittent nature of wind and photovoltaic. The paper reports the results of optimization of hybrid energy system model of a remote area of Jaunpur block of Uttaranchal state of India. The model has been developed with the objective of minimizing cost function based on demand and potential constraints and optimized using computer programme developed in C++. The economic analysis has resulted in the calculation of capital cost, cost of energy for different types of resources and optimized cost of hybrid energy system. To consider the fluctuation in the discharge and power generation from SHP, the EPDF has been varied from 1.0 to 0.0.

With the eigenvalues, the maximum reactive power can be directly determined which can be used as limits for the range of operation.

Its simple structure, rugged behavior, and economical manufacture ability makes them attractive for industrial applications. However, these merits are over shadowed by its inherently nonlinear characteristics, acoustic noise, and complexity of control. This paper discusses the practical approach of finding optimum drive parameters to control switched reluctance motor. The technique mentioned in this paper requires the test run of motor at given speed and torque for formation of lookup tables referred as training mode and then motor can be switched to normal run referred as operational mode. Eventually this technique does lead to low cost control of switched reluctance machines.","PeriodicalId":291800,"journal":{"name":"2007 International Conference on Electrical Engineering","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121372268","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}

Conducting experiments for extracting information about protein sub cellular localization is both time consuming and costly effort. Machine learning approaches, especially, ensemble of classifiers, providing efficient and reliable mechanism of computational prediction are thus highly desired In this context, we propose a modification to the approach proposed in [K. C. Chou, J. Cell. Biol. 99(2006)517]. We have used a weighted polling method to fuse the output of individual covariant discriminant classifiers. The individual classifiers are trained on features based on pseudo-amino add composition of proteins. Three methods of verifications; re-substitution, Jackknife, and independent data set tests have been employed and give over all accuracies of 87.13%, 71.15% and 74.90% respectively.

In order to implement OBS control plane three types of control and reservation architectures have been presented in literature e.g. centralized, distributed and hybrid. The hybrid architecture, presented by the authors, inherits the best features of distributed and centralized architectures such as scalability features of distributed model and best resource utilization of centralized model, In this paper a dynamic resource management for the hybrid architecture in the OBS network is presented. A design of different database tables required by different software modules to manage network resources during connection establishment/teardown phases is presented.
