The initial geometries of the machine are estimated using a series of empirical rules. Due to the complex geometry of the doubly salient structure and the highly nonlinear nature of the motor, a detailed analysis of the electromagnetic performance of SRM is essential to fine-tune the preliminary design. Static electromagnetic modeling alone without considering the electrical transient operation of the motor is insufficient to predict the performance of the motor. Hence, a simulation model of SRM, which takes into account the nonlinear magnetization data obtained from finite element (FE) analysis, is built to study the dynamic behavior of the motor. The final design of the SRM, and its associated power converter and controller, have been prototyped. Various tests have been carried out and the measured results show that the prototype works as expected.","PeriodicalId":6865,"journal":{"name":"2016 IEEE Student Conference on Research and Development (SCOReD)","volume":"2 1","pages":"196-199"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84160379","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}

By minimising the signal power variation, the desired bit error rate of the desired user can be achieved while causing minimum interference to other multiple access users. We investigate two power control algorithms. Namely, the conventional fixed step-size power control algorithm and the newly proposed adaptive step-size algorithm. Simulations on a frequency selective fading, L-resolvable multipaths reverse link system were carried out.

This method exploits a DC approach for constructing a dictionary in fault diagnosis using the neural network's classification capability. Also, Radial Basis Function (RBF) and backward error propagation (BEP) networks are considered and compared for analog fault diagnosis. The primary focus of the paper is to provide robust diagnosis using a mechanism to deal with the problem of component tolerance and reduce testing time. Simulation results show that the radial basis function network with reasonable dimension has double precision in fault classification but its classification is local, while the backward error propagation network with reasonable dimension has single precision in fault classification but its classification is global.","PeriodicalId":6865,"journal":{"name":"2016 IEEE Student Conference on Research and Development (SCOReD)","volume":"4 1","pages":"317-321"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81859762","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 Web camera or Web cam is used as a video clip capture device and MATLAB version 6.01 with Image Processing Toolbox is used as the analysis software. Image frames extracted from the video clips undergo image subtraction for motion detection purposes. The continuous steps presented in this paper are thresholding, noise removal and motion region estimation. Thresholding determines the areas of output images (from subtraction) consisting of pixels with values lying within the threshold value range. Threshold value also indicates the sensitivity of motion to detection. The image still contains a small amount of noise after thresholding. Noise is removed using a median filtering method. Motion region estimation is done by executing an AND or OR operation on two subtracted images from three successive frames. Both the output image from AND and OR operations will estimate the motion region in a different time frame.","PeriodicalId":6865,"journal":{"name":"2016 IEEE Student Conference on Research and Development (SCOReD)","volume":"28 1","pages":"352-355"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83664377","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}

Our method is based multi-scale medical image interpolation for zooming images. Magnetic resonance \"MR\" scans diffusion imaging of the brain. Images based on these parameters show potential for use in the differentiation of gray and white matter, edema, and tumor. A bicubic filter was implemented to recognize the tumor in digital images of the brain. This paper describes the basic achievement in the detection of tumors in medical images. The basic concept is that local textures in the images can reveal the typical regularities of the biological structures. The analysis of the level of correction has permitted us to decrease the number of the features to only the significant components. The level of recognition is among three possible types of image area: tumor non-tumor and background. The essential characteristics of the bicubic such as high resolution and accuracy, are exploited to distinguish between the three features. In fact, the concept of distinguishing normal and tumor tissue with MR imaging goes back to the contrast agents, who described substantial differences between normal and cancerous tissue. In gray scale images the determination of the tumor margin based on contrast margin in MRI images makes an unclear view for normal brain tissue and tumor tissue. Multi-scale images are required for obtaining the detection accuracy of the MRI view.","PeriodicalId":6865,"journal":{"name":"2016 IEEE Student Conference on Research and Development (SCOReD)","volume":"61 1","pages":"356-359"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86288778","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}

Capacity, coverage and quality are general key drivers in deploying any wireless system and they are all a function of SIR. Expanding capacity through conventional methods such as deploying new cell sites or new equipment upgrading is expensive and not always effective as it will introduce more interference in the current network. With the emerging of smart antenna technology, some performance improvement over conventional cellular systems is expected. This paper studies the use of a switched beam smart antenna system in a mobile communication system for reducing cochannel interference. Simulation has been carried out for the GSM cellular system employing various antenna techniques such as omnidirectional, directional and switched beam smart antenna. SIR performances are analyzed and results are compared with those obtained when omnidirectional and directional antenna patterns are used in base stations. SIR improvement of at least 6 dB throughout the network is achieved when the switched beam smart antenna technique is applied in the system.","PeriodicalId":6865,"journal":{"name":"2016 IEEE Student Conference on Research and Development (SCOReD)","volume":"25 1","pages":"422-425"},"PeriodicalIF":0.0,"publicationDate":"2002-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87885758","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}
