Operation of wind turbines has an impact on the power quality and reliability at the connected electric network. Power quality problems such as voltage flicker and harmonic distortion along with reliability issues are some major concern and in this work the flicker & harmonics issues are considered. Wind turbine connected to an induction generator and synchronous generator is modeled using PSCAD software to analyze power quality and reliability problems. Due to continuously varying wind speed components, the active and reactive power along with terminal voltage fluctuates continuously. A new type of static synchronous compensator (STATCOM) unit is developed to inject reactive power by switching IGBT(s) to mitigate power quality problems and to get stable grid operation. By connecting proposed Electro-Mechanical Switched Capacitor (EMSC) based STATCOM into the grid, reactive power and terminal voltage can be controlled effectively with varying wind speed.","PeriodicalId":6490,"journal":{"name":"2015 International Conference on Electrical & Electronic Engineering (ICEEE)","volume":"4 1","pages":"105-108"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76312844","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 classification is carried out to distinguish the seizure segments from the non-seizure ones. The higher order moments (specifically variance) have been calculated in various sub-bands in the wavelet transform domain and utilized as the discriminating feature in the Support Vector Machine(SVM) classifier. The method is tested on 175 hours of continuous EEG data from five patients and on an average, 99% accuracy has been achieved with very high values of sensitivity and specificity. Furthermore, on the basis of the figure of merits, for their excellent performance for all the patients, seven channels have been selected for the patient-invariant seizure detection which might help the electroencephalographers reducing their laborious job of monitoring the EEG data from all the channels.","PeriodicalId":6490,"journal":{"name":"2015 International Conference on Electrical & Electronic Engineering (ICEEE)","volume":"36 1","pages":"77-80"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76770472","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}

Typically, the curvelets-based reconstruction better preserves the image features while the wave atoms-based reconstruction better preserves the oscillatory patterns of the typical ultrasound RF signals. We exploit the advantages from both the sparsifying bases via concatenating them where the RF reconstruction is done from the larger coefficients of the combined basis. We show that the CCW-based reconstruction method better recovers the RF oscillatory patterns as well as preserves the image features better than those of the curvelets- and wave atoms-based reconstruction methods alone. We find improvement with respect to the current methods of approximately 58% and 64% in terms of the normalized mean square error for the reconstructed synthetic phantom and in vivo RF data, respectively. We also show visual performance improvement in the B-mode images of approximately 33% and 44% in terms of the mean structural similarity for the synthetic phantom and in vivo data, respectively.","PeriodicalId":6490,"journal":{"name":"2015 International Conference on Electrical & Electronic Engineering (ICEEE)","volume":"6 1","pages":"209-212"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85006671","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 dependency of the short circuit current (Isc), maximum power output (Pm), and efficiency (η) on the incident angle of illumination and optical gain of the concentrator have been analyzed in this manuscript. Simulation of the performance parameters of the bifacial module has been accomplished to estimate the average electrical output from summer to winter solstice. It has been possible to obtain more than 180 % enhancement in Isc, 250 % in Pm, and 35 % in η from the rear surface of the module when integrated into Sea Shell concentrator.

We report on the development of universal interpreter software (UIS) that can be used by both the American and the Bangladeshi users. For this, an efficient method is proposed for skin detection & feature extraction. Our system can recognize 16 Bengali words & 11 Bengali numbers. We train our system using a database of (27×10×20) images, i.e. 10 persons containing 20 images per sign & for testing we use another 2700 (27×10×10) images.
