This paper proposes a new method to detect power swing as well as different types of faults during power swing. The power swing caused by various disturbances will affect the behavior of distance relay and leads to unnecessary operation of distance relay. However the relay should operate whenever a fault occurs. The Distance relay is more reliable if it discriminates the conditions of power swing and power system faults during power swing. In this paper such type of relay is implemented and it is tested under different faults at normal condition along with the faults during power swing. The results are carried out in MATLAB/SIMULINK.

A solid core photonic quasi-crystal fiber (PQF) is a novel microstructured optical fiber which could provide a large nonlinearity and a low dispersion, which, in turn, could be exploited for generating few cycle laser pulses. We look for the hitherto mentioned optical properties in the proposed PQF by carefully changing the geometrical parameters, namely, core diameter and the pitch. We report a large nonlinearity (γ = 588.2993 W-1 m-1) and a low dispersion (≈ 0.095 ps/nm.m) for operating wavelengths from 1200 to 2000 nm.

The performance of Vector Controlled Induction Motor (IM) Drives to a large extent depends on the accuracy of inverse rotor time constant (1/Tr) estimation which in turn mainly depends on the value of rotor resistance which vary with temperature. Generally, MRAS techniques are widely used for 1/Tr estimation. In this paper, Rotor Flux based MRAS (RF-MRAS) and Real Power based MRAS (RP-MRAS) for 1/Tr estimation is designed and validated through simulation. The performance of these two methods are analyzed extensively and compared in terms of accuracy, settling time and computational complexity. The suitable method of 1/Tr estimation for induction motor drive is identified. The interesting results obtained are presented.

This paper presents the position control scheme of DC servo motor drive. The fuzzy PI controller is developed for controlling the position of DC servo motor drive. The DC servo motors are highly preferred because of high power rating and speed of the motor. The proposed technique is a closed loop real time control scheme where the position control is obtained through position sensor, it is coupled with the motor shaft for provide a feedback position signal. The position control scheme of DC servo motor drive incorporating the fuzzy logic control which is experimentally implemented using a digital signal peripheral interface controller dspic 30F2010. The performances of the proposed fuzzy logic controller based DC servo motor drive were investigated and it is compared with conventional PI controller based drive. The simulated and experimental results of conventional and fuzzy controller is compared and results illustrates that the FLC gives better dynamic performance also it is more robust for industrial position control drive applications.

This paper presents a non-isolated multi-output converter with four outputs. Only two switches in a half-bridge configuration are required to generate the four outputs. More outputs are also possible without the need of any additional switch. A reference sine wave signal of a particular frequency is generated for each of the outputs. The amplitude of the sine wave is modulated based on supply and load variations. The sum of the various reference sine waves drives a half bridge converter. The square wave output from the half-bridge converter is passed through a low pass filter to minimize cross regulation between the outputs. It is then filtered using four tuned networks at the same chosen frequencies as the references and then rectified to obtain the required outputs. An analysis of the converter is done to show that control is possible by amplitude modulation of the reference sine waves. The design procedure for the resonant components is discussed and a comprehensive simulation of the converter is done for different loads and supply voltages. The results are in agreement with the expectations.

With the introduction and popularization of text to speech convertors, a huge drop in literacy rates is being seen amongst the visually impaired. Also, since Braille is not well known to the masses, communication by the visually impaired with the outside world becomes an arduous task. A lot of research is being carried out in conversion of English text to Braille but not many concentrate on the alternative i.e. conversion of Braille to regional languages. In order to address this issue, in this paper we introduce a novel methodology to convert Braille characters representing the Kannada Language (a popular language of southern part of India), captured by a camera, into Kannada text or speech. An automated thresholding algorithm for segmentation of the Braille dots along with a novel algorithm for identification of the characters has been explained. All algorithms were designed and developed for a Xilinx Spartan 3E FPGA and were executed in real time. An accuracy of over 94% was achieved in Braille segmentation and detection. The algorithm for identification of the Kannada Braille character was found to be four times faster than many existing methodologies, on the FPGA.
随着文本转语音转换器的引入和普及，视障人士的识字率大幅下降。此外，由于盲文不为大众所熟知，视障人士与外界的沟通成为一项艰巨的任务。在英语文本到盲文的转换方面进行了大量的研究，但很少有人关注盲文到地区语言的转换。为了解决这个问题，在本文中，我们介绍了一种新颖的方法，将相机捕捉到的代表卡纳达语(印度南部流行的语言)的盲文字符转换为卡纳达语文本或语音。一种自动阈值算法分割盲文点以及一种新的算法识别的字符已被解释。所有算法都是在Xilinx Spartan 3E FPGA上设计和开发的，并实时执行。在盲文分割和检测方面，准确率达到94%以上。在FPGA上发现，识别卡纳达文盲文字符的算法比许多现有方法快四倍。

This Multilevel inverter technology has recently become known has a very important substitute in the area of high power medium voltage energy control. Though multilevel inverter has several advantages it has drawbacks like for higher levels more number of semiconductor switches needed this may lead to huge size and cost of the inverter is very high. So in order to overcome this problem a new multilevel inverter is proposed with reduced number of switches. The proposed topology has three Dc sources and six Switches and it is well suited for high power applications. Level shifted PWM technique is used to generate the sine wave for the proposed topology. The Circuit is simulated in Matlab/Simulink and effect of harmonic spectrum is analyzed through the Fast Fourier transform window. The performance parameters of the proposed multilevel inverter are compared with the conventional MLI and another seven level existing topologies.

This Paper analyzes the application of Static Synchronous Compensator (STATCOM) to prevent the transient voltage instability of power systems due to the presence of large induction motor loads at the terminals of long transmission lines. The analysis is supported by transient time simulations for the complete power system following large disturbances. The effect of induction motor loads on transient voltage stability of power system is studied by applying a disturbance. A disturbance is created either by line tripping or applying a three phase fault. Voltage instability phenomenon is simulated by adding induction motors in parallel and increasing the load. The effect of STATCOM on transient voltage stability of power system is studied. Transient stability analysis is carried out for two sample systems namely 3-bus and 9-bus systems and the results are presented.

This paper presents a comparative study of the segmentation of satellite images in RGB and HSV color space using modified fuzzy c means clustering algorithm. The segmented images are compared with the original input images by using number of bivariate image quality parameters. These parameters measure the similarity between the input and the segmented image on the basis of comparing the corresponding pixels of the two images and present a numerical value as a result. The experiments are performed on GeoEye-1 satellite images to test the efficiency and robustness of the proposed method.
