The −10 dB bandwidth of lower and upper resonance frequency is 4.13 % (experimental 3.4 %, simulated 3.51 %) and 8.82 % (experimental 8.79 %, simulated 8.78 %) respectively. The frequency ratio of the antenna for a given dimension of L-slot is found to be 2.092 (experimental 2.098, simulated 2.097). The theoretical results are compared with the simulated results obtained from IE3D which are in close agreement.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128927619","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 reduction in power losses that this technology provides in power conversion systems is enabling a quicker adoption of alternative energy systems, improving existing technology and allowing a reduction in future fossil-fuel consumption. As these devices are further optimized in the coming years we can expect even better performance results. SiC Schottky diodes that are commercially available today and the pending introduction of SiC DMOSFETs will help develop much more efficient next generation alternative energy systems and greatly improve power supply, motor drive and UPS efficiencies.

This, in turn, has led to the emergence of highly sophisticated simulation software applications that not only enable high-fidelity simulation of dynamic systems and related controls, but also automatic code generation for implementation in industrial controllers. Today, electric drives, power electronic systems and their controls are getting more and more complex, and their use is widely increasing in all sectors: power systems, traction, hybrid vehicles, industrial and home electronics, automotive, naval and aerospace systems, etc. Advances in Microprocessors, Microcomputers, Microcontrollers such as DSP, FPGA, dSPACE etc. and Power Semiconductor devices have made tremendous impact on electric motor drives. Due to advancement of the software tools like MATLAB/SIMULINK with its Real Time Workshop (RTW) and Real Time Windows Target (RTWT), real time simulators are used extensively in many engineering fields, such as industry, education and research institutions. As consequences, inclusion of the real time simulation applications in modern engineering provides great help for the researcher and academicians. A case is made to present overview of the Real Time Simulations of Electrical Machine Drives possibility of including these techniques in modern engineering and practices.

The objective is to minimize a first order cost function subject to linear constraints. The dynamic analog circuit, consisting of N identical units for N variable problem, can solve the general LPP and always converges to the optimal solution in constant time, irrespective of the initial conditions, which is of the order of its time constant. The proposed circuit employs non-linear feedback, in the form of Differential Voltage Current Conveyor (DVCC) based unipolar comparators, to introduce transcendental terms in the energy function ensuring fast convergence to the solution. Further, the use of resistors to generate weighted inputs to the neurons is avoided. Instead, DVCCs are utilized to directly generate the required scaled currents. PSPICE simulation results are presented for a chosen optimization problem and are found to agree with the algebraic solution.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127007551","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 network has been used as pattern classifier for detection, identification and classification of the internal faults. The full cycle data of simulated fault currents in the phases and their parallel paths have been used for training and testing of proposed neural networks. The synchronous generator model based on direct phase quantities and modified winding function approach has been used to simulate different types of internal and external faults using electrical parameters of generators being used by utilities. All possible cases of internal faults in the stator winding have been considered and networks have been trained and tested accordingly. The test results of the selected architecture of the networks for different protection schemes indicate that the fault signal can be correctly identified and classified by the proposed networks.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115045515","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}

Six research questions guided the study. Descriptive survey design was employed for the study and the population consisted of all registered undergraduate students of U.N.N and N.A.U. with a total of 35,854 from both universities, out of which seven hundred and twenty students were sampled. Stratified random sampling technique was used for the study. The instrument used for data collection was questionnaire. The questionnaire has 61 items. Descriptive statistics including frequency tables, percentages and mean were used to answer research questions. The finding revealed that: undergraduate students’ use of electronic information resources enhances their access to a wider range of information, most of them prefer to use internet for their academic work, and they prefer to use phones and laptops as their sources of electronic information resources. They are motivated to use electronic resources because they provide quick access to information. The study also revealed that some electronic resources like CD ROM, Library portals, wire radiophone, news group, and online public access catalogue (OPAC) were not popular among the students. However, the students face the problem of limited access to computer terminals, slow internet connectivity, irregular power supply, lack of IT knowledge to effectively utilize the electronic information resources services, as well as inadequate time to access electronic information resources due to pressure from academic work. Some of the strategies for improving the academic use of electronic resources by the students include giving them more education on the use of electronic information resources, provision of more computers in the university libraries, provision of free internet connectivity to students within the university and providing constant power supply among other suggestions.","PeriodicalId":439893,"journal":{"name":"2010 International Conference on Power, Control and Embedded Systems","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114008759","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}
