Parameter sensitivity analysis of Direct Torque Control(DTC) scheme for dual inverter fed open end winding induction motor drive with single DC source is presented in this paper. The effect of stator resistance variation on the voltage vector selection in this DTC scheme is analysed using the voltage space structure of a dual inverter configuration with single DC source. Theoretical analysis is validated by simulation on a MATLAB Simulink platform. The results of the theoretical and simulation analyses are experimentally verified on an induction motor with open-end stator windings using TMS320F28335 digital signal processor.

X-ray images are widely used for detecting defects of bone in medical applications. The images are corrupted by noise during the acquisition process which causes loss of visibility to detect the bone features. This paper depicts a way to improve the view of an image where image enhancement techniques play an important role. Here, an X-ray image enhancement model based on discrete wavelet transform and histogram matching technique is proposed under the assumption that enhancement of high frequency component of an image increases it’s sharpness. Therefore, vertical detail of Haar wavelet transform is considered here. Finally, histogram specification technique is used to increase the visibility of the images. Experimental results show that the algorithm can effectively enhance the medical X-ray images.

Reversible logic has received great attention in last few years as it dissipates very low power. This paper presents the reversible logic synthesis for the n-to-2n fault tolerant decoder, where n is the number of data bits. A low cost 6 × 6 reversible gate is proposed to design a 2-to-4 reversible fault tolerant decoder which has least delay. An algorithm is derived to construct higher bit order decoder. Theoretical explanations certify the novelty of the proposed design. Comparing with previous works, the proposed design shows significant reduction in gate count, quantum cost and delay, which are 66.66%, 8.33%, 16.66%, respectively, with respect to the corresponding metrics of the best existing 2-to-4 fault tolerant decoder. Area and power consumption of the proposed circuit are also estimated.

Securing an organization with proper authentication is a challenge. Intruders are always active and pose thread to anyone. And, attaining cost-effective system with high accuracy is a management perspective. Hence, in this paper we propose a low-cost reliable biometric system based on finger vein patterns. The proposed algorithm initially captures the finger vein image and is preprocessed to remove possible noise and distortion. Geometrical features like corner points and their location are extracted. These features will play the role in authenticating any individual. The simulation results of the proposed algorithm have shown the FAR as 4.72%, FRR as 1.9% and the overall performance as 98.11%.

This article proposes a novel method for solving traffic signal coordination problem under over-saturated conditions. This problem is a large combinatorial optimization problem formulated as a dynamic optimization problem. The algorithm derives optimal green times for a network consisting of 20 interconnected signals using termite spatial correlation optimization (TSCO) algorithm. The algorithm tries to do so by incorporating proper queue dissipation along with maximizing number of vehicles precessed by the network in the congestion period. The resulted green times and fitness values have been compared with those derived using Genetic Algorithm (GA) and Ant Colony Optimization (ACO). TSCO is shown to outperform GA and ACO in terms of fitness value as well as overall function evaluations.

In this paper, time-frequency domain operation exploiting Empirical Mode Decomposition (EMD) is performed on EEG signals to classify normal activity of healthy person, non-seizure (inter-ictal) and seizure (ictal) activity of seizure patients. Analyzing power spectral density estimation in the set of Intrinsic Mode Functions (IMFs) by periodogram, it is seen rational to specify some prominent IMFs to use in classification problem. Bimodal distribution which is two components Gaussian statistical model is utilized in specified leading IMFs to summarize information in it and propose feature set using the modeling parameters of two component Gaussian probability density function (PDF). Empirical and Gaussian PDF have been plotted along with Kolmogorov-Smirnov (K-S test) goodness-of-fit hypothesis test and found Gaussian statistical model most effective to feed modeling parameters of Gaussian PDF in SVM and ANN classifier for normal, inter-ictal and ictal stages of seizure classification. The proposed technique is accomplished with making higher sensitivity, specificity and accuracy compared to that made by an up-to-date method while wide range of simulations were performed using the same benchmark EEG dataset and classifier.

Gallium nitride based DG-MOSFETs with multiple gate lengths has been designed for the next generation logic applications. SILVACO ATLAS has been used to access Nonequilibrium Green’s function. The device turn on and turn off voltage (Gate-Source) is respectively, $text{V}_{mathbf {GS}} =$ 1 V (ON-state) and $textbf{V}_{mathbf {GS}} =$ 0 V (OFF-state). To improve high-speed performance from the concept of solid state device physics, effects of changing various characteristics for a different gate length of DG-MOSFETs were studied. Effects of the device are analyzed by varying various gate length ($textbf{L}_{mathbf {G}} =$6 nm to 10 nm). The device performance metrics such as $textbf{I}_{mathbf {ON}}$, sub threshold slope (SS) and drain induced barrier lowering (DIBL) has been done for multiple gate lengths. The simulated device verifies GaN-based DG-MOSFETs for various gate length for the next generation high speed, high performance (HP) and logic applications and VLSI technology.

Effects of the device are analyzed by varying various gate length ($textbf{L}_{mathbf {G}} =$6 nm to 10 nm). The device performance metrics such as $textbf{I}_{mathbf {ON}}$, sub threshold slope (SS) and drain induced barrier lowering (DIBL) has been done for multiple gate lengths. The simulated device verifies GaN-based DG-MOSFETs for various gate length for the next generation high speed, high performance (HP) and logic applications and VLSI technology.","PeriodicalId":188031,"journal":{"name":"2017 IEEE International WIE Conference on Electrical and Computer Engineering (WIECON-ECE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116203504","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}

This paper presents the application of electric system cascade analysis (ESCA) for optimization of a hybrid system consisting of wind energy conversion system (WECS), photo-voltaic generation (PVG), battery energy storage system (BESS) and non-intermittent source like bio-mass generator (BMG). The paper aims to show the application of ESCA for a hybrid system by finding the optimized size of the generating units with final excess energy (FEE) as the optimization constraint and also compare three system configurations, i.e. non-intermittent source only, with intermittent source only and a hybrid system comprising of both these sources with a predefined renewable energy fraction (REF).
本文介绍了电力系统级联分析(ESCA)在由风能转换系统(WECS)、光伏发电(PVG)、电池储能系统(BESS)和生物质发电机(BMG)等非间歇源组成的混合系统优化中的应用。本文旨在通过寻找以最终剩余能量(FEE)作为优化约束的发电机组的优化尺寸来展示ESCA在混合系统中的应用,并比较了三种系统配置,即仅非间歇源,仅间歇源以及由这两种源组成的混合系统具有预定义的可再生能源分数(REF)。
