The bulk polycrystalline Bi0.9Dy0.1FeO3 samples were synthesized using solid state reaction technique and their nano counterparts were prepared using ultrasonic probe sonication. XRD patterns demonstrated significant improvement of phase purity due to Dy substitution both in bulk sample and corresponding nanoparticles. Again, FESEM imaging was carried out to analyze the surface morphology of bulk sample as well as to determine the size and distribution of the synthesized nanoparticles. Furthermore, leakage current density measurements were performed where, interestingly, we found comparable performance for Bi0.9Dy0.1FeO3 bulk and its corresponding nanoparticles. Moreover, the polarization versus electric field measurements showed higher remanent polarization and coercive field for nanoparticles compared to their bulk samples which might be associated with leaky behavior generated from oxygen related defects of the nanoparticles. However, saturation polarization within the applied field range was observed for Bi0.9Dy0.1FeO3 bulk only indicating inherent ferroelectric behavior. Overall, this investigation provides evidence of Bi0.9Dy0.1FeO3 multiferroic having enhanced structural purity and ferroelectric properties over undoped BiFeO3. In particular, it opens up the pathway of a material with equivalent bulk and nano leakage current performance which may be useful in many applications.","PeriodicalId":122930,"journal":{"name":"2016 9th International Conference on Electrical and Computer Engineering (ICECE)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132178573","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}

Recently a “single bin Fourier transform algorithm” has been proposed by the present authors, which is designed to compute the spectral amplitude and phase of a single frequency present in the time signal to be analyzed. The traditional detection scheme involves sampling the analog signal first using the Nyquist's sampling theorem, apply the FFT on the sampled signal and then identify the desired frequency from the FFT output. However, in case of tone detection, only the presence of a single frequency is to be tested. The computation of the whole FFT output dataset is superfluous in this case. In this paper, we have used the single bin Fourier transform algorithm for tone detection, which makes the detection scheme less complex and computationally more efficient than the traditional FFT algorithm. Moreover, the method of parallel processing can be applied to make the system more efficient in detecting the existence of more than one frequency component present in the incoming signal. The main objective of the proposed scheme is to improve the detection speed of a single frequency, or a narrow band of frequencies, present in a signal.","PeriodicalId":122930,"journal":{"name":"2016 9th International Conference on Electrical and Computer Engineering (ICECE)","volume":"1 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113963407","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}

For low DC voltage output requirement of LED driver, Cúk converter is a convenient choice due to its topological suitability for PFC application and stepping the voltage down at a desired level unlike the Boost Converter. A hysteresis current control scheme is adopted to operate the converter in Continuous Conduction Mode (CCM) and fast enough to follow the current reference causing power factor to approach near unity. Although the converter operates at variable switching frequency, the response is very fast and independent of the converter dynamics. At the same time the converter ensures a constant current drive at the output side to operate the LED. Theoretical analysis, design calculation and simulation results confirm that the proposed single stage control scheme operates with an improved THD and performs better compared to the commercially available controller because the same converter is used for both PFC and LED Driver. As it diminishes one stage of power conversion, the efficiency of the driver is increased whereas the complexity in controller design and implementation is decreased.","PeriodicalId":122930,"journal":{"name":"2016 9th International Conference on Electrical and Computer Engineering (ICECE)","volume":"71 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132880355","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}

According to a report of International Osteoporosis Foundation, at least one in five men and one in three women in Bangladesh suffer a bone fracture due to osteoporosis in their remaining lifetime. Limited data is available in the open literature on osteoporosis among women in Bangladesh and more so on the micro-structural analysis of osteoporosis. The present study particularly aims at identifying the trend of osteoporosis of women of in Bangladesh, with special emphasis on the mechanical micro-structural analysis of female bones. A comprehensive statistical analysis has been conducted by collecting data of 250 Bangladeshi females with age ranging from 20 to 80 years. Trabecular bones of Tibia of female have been analysed with computed tomography for micro-structural assessment. To characterize several parameters of trabecular bones, the computed tomography scans have been analysed and parameters like bone volume fraction, fractal dimension etc. have been evaluated. A correlation between structural properties of the bones has been formed by multiple regression analysis. It shows a positive correlation between fractal dimension and bone volume fraction of the specimens.","PeriodicalId":122930,"journal":{"name":"2016 9th International Conference on Electrical and Computer Engineering (ICECE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132899411","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}
