Appliance Control using Short Message Service (SMS)
Georgekutty P. P
Abstract: This paper describes the design and implementation of a GSM-based password-protected control system for electrical home appliances that allows for remote control. The GSM module is used to receive short message service (SMS) messages from the user's mobile phone, which automatically allows the controller to take further action such as turning on or off home appliances such as lights, air conditioners, fans, water pumps, door locks, TVs, and so on. The system's hardware was created using an Arduino Uno board, GSM modules, switching relays, and other readily available electronic components. The Arduino IDE was used to create the driving software. When only the user sends the SMS to the controller at home with the exact password, the system is activated. When the microcontroller unit receives an SMS command, it automatically decodes it and controls the electrical home appliances by turning them ON or OFF based on the user's instructions.

Blur And Illumination Robust Face Recognition Using Bayes Classifier
MR.M.SATHEESH KUMAR, MRS.S.SANGEETHA
Abstract: Human face recognition by computer systems has become a major field of interest. Face recognition algorithms are used in a wide range of applications like security control, video retrieving, Biometric signal processing, human computer interface, image database management, etc. It is difficult to develop a complete robust face detector due to various light operating conditions, different face sizes and face orientations, background and skin colors. This paper, proposes a face recognition method for locate the problem of unconstrained face recognition from remotely acquired images. The main factors to affect this system is challenging are image degradation due to blur, appearance variations due to illumination and pose. In this paper, using a blur-robust algorithm based on PCA with Euclidian(K-NN) Classifier, is a non-parametric method for classification and regression, which predicts objects' "values" or class memberships based on the Nth closest sampled examples in the feature space. In Future of the work propose a blur-robust algorithm based on Eigen Face with Bayes classifier whose main step involves a simple probabilistic classifier based on applying Bayes' theorem with strong independence assumptions. Finally to compare both the face recognition methods and prove that the proposed method is better by overcoming the disadvantages of existing method. A computer simulation using MATLAB/SIMULINK confirms the predicted results.

The DTC is one of the most excellent direct control strategies of stator flux and torque ripple of IMD. The conventional method of DTC, it uses PI for speed regulator where speed reduced under transient and dynamic state . This drawback was reduced by the proposed system the speed is regulated by PI and torque is controlled by fuzzy logic controller. The control system is based on DTC operating principles.

SIMULTION OF A Boost Converter Based Bootstrap Capacitor and Boost Inductor for PMDC Drive
DR. T.GOVINDARAJ, G.NAGARAJAN
Abstract: In this project, novel high voltage-boosting converters are presented. By changing the connection position of the anode of the diode and by using different pulse-width-modulation control strategies, different voltage conversion ratios can be obtained. These converters are constructed based on bootstrap capacitors and boost inductors. Above all, two boost inductors with different values, connected in series, can still make the proposed converters work appropriately. Furthermore, although there are three switches in each converter, only one half-bridge gate driver and one low-side gate driver are needed, but no isolated gate driver would be needed. After some mathematical deductions, some experimental results are provided to verify the effectiveness of the proposed converters. A new voltage-boosting converter, combining a charge pump and a coupling inductor, together with a passive voltage-clamping circuit which pumps part of the leakage inductance energy to the output, is presented herein. Therefore, by doing so, the efficiency tends to be flat between the minimum and rated loads. Moreover, the implementation of the passive voltage-clamping circuit for this converter with multiphase is very easy. In this paper, some mathematical derivations are given first, and second, simulated and experimental results are provided to verify the effectiveness of the proposed voltage-boosting converter topology.

A Wide Area Monitoring System Using Neuro Control Technique for Load Restoration
DR. T.GOVINDARAJ, J.JAYASUJITHA
Abstract: System restoration following a blackout is one of the most important tasks for power system planning and operation. The restoration process returns the system back to a normal operating condition following an outage of the system. With the development of the wide area monitoring system (WAMS) using neuro control technique, voltage can be controlled and power system operators are capable of accessing to more accurate data in the restoration stage after a major outage. In this work, a restorable load estimation method is proposed by employing WAMS to monitor the system parameters in case the newly recovered system becomes unstable again. The concept of power conversion from renewable energy sources is included to compensate voltage sag during addition of new loads are analyzed and simulated using MATLAB. This improves the overall system reliability and avoids cascaded blackout during fault occurrence.

MIRZA MUKRAM BAIG, MD WAJID HUSSAIN M-TECH, IMTHIAZUNNISA BEGUM M-TECH, MD ABDUL KHADER, CS SADAQ BASHA
Abstract: Beam forming is a signal processing technique used in antenna arrays for directional signal transmission or reception. Phased array radar is very important in modern radar development, and multiple digital beams forming technology is the most significant technology in phased array radar. Digital multiple beam forming on each antenna element about large phased array radar is impossible in processor based digital processing units, because it needs simultaneous processing many A/D channels.
This paper describes architecture for a digital beam former developed for 16 element phased array radar. The digital beam former architecture includes the complex operations such as down conversion which is done in parallel for the signal coming from each of the antenna elements and the filtering. A high performance FPGA is employed to perform these operations. An echo signal of 5 MHz riding on the IF signal of 60 MHz is down converted digitally to the baseband of the echo signal. The baseband echo signal is then multiplied by the complex weights and then summed to form the beam. The prototype architecture employs 16 bit 125 MS/s ADCs and a very high performance state of the art Xilinx FPGA device Vertex 6vlx240t to form the 112/4/6/9 beams simultaneously. The device used has large number of on chip resources for the parallel processing and the 200MHz clock generator. The complex weights are externally calculated using highly stable Q-R decomposition based recursive least squares algorithm and stored inside the FPGA.

Dynamic Reactive Power Control of Islanded Microgrid Using IPFC
DR. T.GOVINDARAJ, D.HEMALATHA
Abstract: This paper discusses the dynamic behavior of flexible ac transmission system devices such as Interline Power-Flow Controller (IPFC). The interline power flow controller (IPFC) proposed is a new concept for the compensation and effective power flow management of multi-line transmission systems. The advantage of this method is that it can avoid unstable voltage conditions in micro grid by prediction of the instability ahead of time. This method can also avoid voltage drops or swells in any of the phases of the system. This capability makes it possible to equalize both real and reactive power flow between the lines, transfer power from overloaded to under loaded lines, compensate against reactive voltage drops and the corresponding reactive line power and to increase the effectiveness of the compensating system against dynamic disturbances. The method is used for control action compare to other Voltage and Var Control (VVC) method.

Simulation Modelling on Risk Based Optimal Power Flow Using Bio Inspired Algorithm
DR. T.GOVINDARAJ, S.DINESH
Abstract: Optimization of power system operation is vital for ensuring economics and security. This works considers optimization of fuel cost for achieving economics with security as a constraint. The real power outputs from generators are the control variables in optimal power flow (OPF). Conventional OPF minimizes only the fuel cost. Adequate security with regard to line flow violation is not guaranteed. This works takes into account the line flow as a constraint. Security is improved by adjusting the line power flows. The OPF-SC is a nonlinear programming optimization problem with complex discontinuous solution space. Cuckoo search algorithm is a recently developed algorithm known for its simplicity yet good searching capability. The control parameters are the real power generation, generator bus voltage, transformer tap position and SVC settings. The proposed methodology is to be tested on the standard IEEE-30 bus system.

GUI Based Complex Test Pattern Generation for High Speed Fault Diagnosis in Memory Chips
MOHD ARSHAD NAZEER, IMTHIAZUNISSA BEGUM MTECH, KORANI RAVINDER PHD, MD ABDUL KHADER
Abstract: The memory blocks testing is a separate testing procedure followed in VLSI testing. The memory blocks testing involve writing a specific bit sequences in the memory locations and reading them again. This type of test is called March test.
A particular March test consists of a sequence of writes followed by reads with increasing or decreasing address. For
example the March C- test has the following test pattern.
There are several test circuits available for testing the memory chips. However no test setup is developed so far for testing the memory blocks inside the FPGA. The BRAM blocks of FPGA are designed to work at much higher frequency than the FPGA core logic. Hence testing the BRAMs at higher speed is essential. The conventional memory test circuits cannot be used for this purpose. Hence the proposed work develops a memory testing tool based on March tests for FPGA based BRAM (block RAM testing).
The code modules for March test generator shall be developed in VHDL and shall be synthesized for Xilinx Spartan 3 Family device. A PC based GUI t.ool shall send command to FPGA using serial port for selecting the type of test. The FPGA core gets the command through UART and performs the appropriate and sends the test report back to PC. Generally, in the studies of microelectronics engineer the approach of IC testing remains very theoretical. Only few concrete practices are commonly done and generally laboratory experiences are limited to the use of CAD tools. For this purpose, in our teaching department, we develop an experiment allowing a concrete learning of IC testing dedicated to the test of commercial memory chips. Through this environment, our students reached a better knowledge of the connection between the test sequences and the detected faults.

DR.T.GOVINDARAJ, R.THENDRAL
Abstract: In this paper, an efficient quadratic programming has been used for solving economic dispatch problem. The main aim is to obtain minimum fuel cost and emission. Economic emission load dispatch (EELD) problem is solved to minimize the emission of nitrogen oxides and fuel cost, considering both thermal generators and wind turbines. To find the optimum emission dispatch, optimum fuel cost, best compromising emission and fuel cost, a newly developed optimization technique, called Quadratic Programming Method (QPM) has been applied. QPM is based on the Wolfe Modified Simplex Method and Iteration Process. The bus system having six conventional thermal generators has been considered as test system. After placing the wind power sources, those buses have been considered as generator bus. Minimum fuel cost, minimum emission and best compromising solution obtained by QPM.

Simulation Modelling on Harmonic Reduction Using Cascaded Multilevel Inverter fed Induction Drive
DR. T.GOVINDARAJ, P.VIJAYAKUMAR
Abstract: In this project, a multilevel inverter was designed and implemented to operate a stand-alone solar photovoltaic system. The proposed system uses selective harmonics elimination pulse-width modulation (PWM) in the multilevel inverter to convert DC voltage from battery storage to supply AC loads. In the PWM method, the effectiveness of eliminating low- order harmonics in the inverter output voltage is studied and compared to that of the sinusoidal PWM method. This work also uses SHEPWM to predict the optimum modulation index and switching angels required for a nine-level cascaded H- bridge inverter with improved inverter output voltage. The proposed predictive method is more convincing than other techniques in providing all possible solutions with any random initial guess and for any number of levels of a multilevel inverter. The simulation results prove that the lower-order harmonics are eliminated using the optimum modulation index and switching angels. An experimental system was implemented to demonstrate the effectiveness of the proposed system.

Modelling of Stand –Alone Wind Energy Conversion System using Fuzzy Logic Controller
NIVEDITA CHAKRABORTY, MINAKSHI DEB BARMA
Abstract: The concern for environment due to the ever increasing use of fossil fuels and rapid depletion of the conventional sources of energy has led to the development of alternative sources of energy. Wind energy, the kinetic energy associated with movement of large masses of air, is an inexhaustible source of energy which generates electricity without harming our environment. But it is unreliable energy source as wind conditions are uncertain and unpredictable. This paper focuses on developing a fuzzy logic controller based Stand-Alone Wind Energy Conversion System, where this controller manages power production and power storage according to wind conditions & load demand. This proposed system will help us to get a smooth AC output voltage to supply to fixed Load under any wind speed. The effectiveness of the proposed system for its application in autonomous wind energy system is verified with simulation results, which is carried out using MATLAB.

Dr. T.GOVINDARAJ, T.MUTHURAJA
Abstract: This project proposes a zero voltage switching technique based combination of MOSFET inverter and IGBT converter fed PMDC drive. The proposed converter topology reduces voltage stress and conduction losses using zero voltage switching technique and also performs speed control of PMDC motor using PI controller. Proposed converter provides very efficient power conversion due to low voltage stress, less switching losses and requirements of power devices less. The proposed converter topology permits all switching devices to operate under zero voltage switching technique. Moreover, the voltage stress of the primary switches is reduced by using voltage divider which makes the low-voltage rated power devices available to improve the circuit performance and speed control of PMDC Motor using PI controller.

Speed Control of Induction Motor Using Fuzzy Logic Control
DR. T.GOVINDARAJ, G.DIVYA
Abstract: Measurements validation is a critical feature in monitoring systems required by most industry applications to achieve higher level reliability. This paper presents the use of the measurement thresholds generated from the propagation of parametric uncertainty using fuzzy logic to validate the sensor measurements of an induction motor drive by means of fuzzy techniques. If measurements fail the validation check, they are replaced by reconstructed data to maintain the operation. Reconstruction is performed with fuzzy logic, which also supports the evaluation of the thresholds. The algorithms proposed here have been implemented and tested both in simulation and in real time experiments on a field oriented controlled induction machine.

DR. T.GOVINDARAJ, N.SARANYA
Abstract: In this project, quasi network based sparse matrix converter and a compensation method based on a fuzzy logic controller to compensate the input voltage. The structure of an SMC to reduce the number of unipolar power semiconductor switches employs a quasi network to overcome the inherent limitation of the low voltage transfer ratio of conventional matrix converters. Although the SMC is a two-stage converter, it directly connects between a source and a load through a quasi network, which is designed to have smaller passive components as the only purpose is voltage boosting. The operational principle of the SMC is described and its modulation strategy is explained. Simulation results are shown to verify the feasibility of the SMC and its operation.

Optimal Economic Dispatch for Power Generation Using Genetic Algorithm
DR.T.GOVINDARAJ AND M.VIDHYA
Abstract: In this paper, an efficient and practical real- coded genetic algorithm (GA) has been proposed for solving the economic dispatch problem. The objective is to minimize the total generation fuel cost and keep the power flows within the security limits. For each problem of optimization in genetic algorithm (GA) there are a large number of possible encodings. The use of real valued representation in the GA has a number of advantages in numerical function optimization over binar y encoding. The efficiency of the GA is increased as there is no need to convert chromosomes to the binary type, less memory is required, there is no loss in precision by discret to binary or other values, and there is greater freedom to use different genetic operators.

RADHIKA M. JAJU, NILESH N. KASAT
Abstract: The DC-DC power converters are widely used. However, the controller design for DC-DC power converters cannot easily design if load is dynamics vary widely. Therefore a Field Programmable Gate Array (FPGA) is proposed to build a neuro fuzzy system for controlling a nonlinear buck boost converter. A Very High speed integrated circuit Hardware Description Language (VHDL) has been used to implement the proposed controller. The main purpose behind implementation of the NF controller in VHDL is to minimize the hardware implementation cost of the generic NF controller for use in industrial applications. Xilinx ISE 13.1 program has been used as programming environment to type and synthesis the VHDL codes that described the neuro-fuzzy controller and to generate a configuration file which is used to program the FPGA board.

DR.T.GOVINDARAJ, DHIVYA.N.M
Abstract: In this proposed work a control of permanent magnet synchronous motor by using an artificial neural network and the motor is supplied by the voltage source inverter. The inverter gate pulses are controlled by using an artificial neural network. In the proposed system, the speed of the PMSM and the inverter output power are regulated. The system is based on the single artificial neuron which in turn minimizes complexity and computational burden requirements. The maximum power factor is obtained. The ANN based controller precisely and accurately follows command speed and also provides variable speed operation of the motor. This method of using artificial neural network reduces the output current ripples and motor torque ripples hence increases the efficiency.

Signal Correction of Load Cell Output Using Adaptive Method
RAJESH DEY, ATREYEE BISWAS, SUMAN KUMAR LAHA, AMLAN PAL, DR.ACHINTYA DAS
Abstract: This paper presents a method of dynamic compensation of load cell response using Adaptive technique. The case is illustrated by showing how the response of a load cell can be improved. The load cell is a sensor, whose output gives an oscillatory response in which the measured values contribute to the response parameter. Thus, a compensation technique is used to track the variation of the measured values to facilitate the investigation using response compensation. The first step is to make a mathematical model of a load cell. Secondly, the output is digitized by a proper sampler and suitable A/D converter. After verifying the simulated output, a model of an adaptive technique will be made to minimize the oscillation in the output and the corrected digital data again converted to analog form by proper D/A converter for using in real system. The whole system constitutes a dynamic sensor for achieving compensation response.

Lc Series Resonant Circuit Based Soft-Switching Bidirectional Dc-Dc Converter Fed PMDC Drive
DR.T. GOVINDARAJ, S.S.SHABITHA
Abstract: A soft-switching bidirectional dc/dc converter fed PMDC motor with a LC series resonant circuit is proposed. The proposed converter has been obtained by adding LC series resonant tank in the conventional bidirectional dc/dc converter. The conventional type DC/DC converter incorporating the old switching techniques would raises the switching losses and voltage stresses on the devices. The above drawback is rectified with the help of soft switching techniques. The proposed topology performs soft switching at both buck and boost operations. Through the theoretical boost and buck mode analysis, Zero Voltage Switching (ZVS) operation is explained. A zero voltage switching operation of the power switches reduces the switching loss during the switching transition and improves the overall efficiency and the PMDC motor used for low voltage, continuous operation.

Quasi-Z-Source Solar Inverter Fed BLDC Drive using ANFIS MPPT Control
DR.T.GOVINDARAJ, K.HEMALATHA
Abstract: The major players in renewable energy generation are photovoltaics (PV), wind farms, fuel cell, and biomass. These distributed power generation sources are widely accepted for microgrid applications. However, the reliability of the microgrid relies upon the interfacing power converter. This paper proposes an artificial-intelligence-based solution to interface and deliver maximum power from a photovoltaic (PV) power generating system in standalone operation. BLDC motor is connected at the output side which acts as a load and efficiently utilizes the power obtained from solar using ANFIS. The qZSI acts as the interface in between the PV dc source and the BLDC motor. ANFIS promises the maximum power delivery to the load based on maximum power point tracking (MPPT). The proposed ANFIS-based MPPT offers high efficiency and accuracy. The closed loop control regulates the speed of the BLDC motor for different load conditions and also maintains regulated voltage and current. The effectiveness of this proposed method is verified using matlab/simulink software.

Power Line Communication Systems
VIVEK AKARTE, NITIN PUNSE, ANKUSH DHANORKAR
Abstract: This article constitutes an overview of the research, application, and regulatory activities on power line communications. Transmission issues on the power line are investigated and modeling approaches illustrated. Contemporary communication techniques and reliability issues are treated. Power lines constitute a rather hostile medium for data transmission. Varying impedance, considerable noise, and high attenuation are the main issues. The power line communication (PLC) is a new technology open to improvements in some key aspects. Some companies in the world provide broad band PLC devices and an increasing number of utility companies have already gone through field trials and commercial deployment of PLC services. Power-line communications over the low-voltage networks is gaining the attention of researchers in both broadband and narrowband application areas. The transmission characteristics of the power- line carrier are very significant in signal propagation.
The power line modem uses the power line cable as communication medium. It is convenient as it eliminates the need to lay additional cables. The modem at the transmission end modulates the signal from data terminal through RS-232 interface onto the carrier signal in the power line. At the receiving end, the modem recovers the data from the power line carrier signal by demodulation and sends the data to data terminals through RS-232 interface.

PRACHI NAIK, MR. S G KERHALKAR, PROF.N.K.MITTAL
Abstract: Contrast Enhancement is a technique of enhancing the contrast level of the images such that the brightness of the image is preserved. The images takes from the satellite are sometimes seems to be not very bright and may contains noisy pixels. So here a new methodology is adopted to improve the contrast of such satellite images. Although there are various schemes implemented for to improve the contrast level of satellite images, but here the contrast enhancement is done using the fusion of the canny edge of the images and adaptive intensity transfer function of the image on low intensity of the image where the contrast is low detected using DWT transformation. The main idea is to transform the satellite image into subbands where the low subband is further processed to increase the contrast of the pixels, the low intensity pixels are detected using canny edge detector and adaptive intensity function is used to increase the intensity of pixels, the enhanced pixels are then fused with high subband region to make the resultant image.

GOPINATH.M, PRAVEEN.L, RAMALAKSHIMI.P
Abstract: Caches consume a significant amount of energy in modern microprocessors. To design an energy-efficient microprocessor, it is important to optimize cache energy consumption. High-performance microprocessors employ cache write-through policy for performance improvement and at the same time achieving good tolerance to soft errors in on-chip caches. Write-through policy also consumes large power due to the increased access to caches in different level during write operation. In this paper, we propose an efficient low power cache design referred to as way-tagged cache using Pre-Computation Logic. The cache architecture is designed using a Pre-Computational technique in place of the comparators. This helps to achieve low power consumption than existing technique.

A New Approach to Direct Torque Control of Induction Motor Drive with GA Controller for Torque Ripple Reduction
LOKANATH DHALL SAMANTA, BIBHU PRASAD PANIGRAHI, BIBHUTI BHUSAN PATI
Abstract: The Direct Torque Control (DTC) strategy is one of the best strategies of speed control of Induction Motor Drive (IMD). This scheme is simple in structure and produces fast and robust response in A.C drive system. How ever, this scheme is encountered with the possible problems of high torque, flux and current ripples. The deviation of electromagnetic torque from its reference value causes vibration and noise which reduces the efficiency of the drive. The Genetic Algorithm is recently getting growing importance in soft control applications. This paper focuses on the simulation of a Direct Torque Controlled Voltage Source Inverter-fed Induction Motor Drive employing a Refined Genetic Algorithm Controller (RGAC) to encounter the above problems and to devise a more effective method of speed control. Finally, the simulation results of Conventional DTC and RGAC-DTC drive are compared. It is observed that the torque and flux ripples are less in the proposed scheme and offers improved dynamic response.

High Datarate in Multimode Fiber Using Vector Intensity Modulation
P.MASLIN AMIRTHA SHALONIDA, J.SUNIL GAVASKAR
Abstract: Multimode fibers(MMFs) are generally used for transmission of light signals over optical fiber for small distance. Here multimode fibers are used for long haul transmission using vector intensity modulation. By using this method we can obtain higher datarates over multimode fibers.The use of channel feedback preserves the full multiplexing gain and avoid the losses of datarates. This is preffered because the ultimate aim is to improve the robustness of links as well as to increase data rates. Precoding is used for pre processing the signals so that the effective transmission modes can be identified. The vector intensity modulation technique with multiple sources and detectors and post processing minimizes the modal dispersion. The compensation methods improve the bandwidth and the wavelength product of MMFs. By using the above methods a 50% increase over the single laser and detector is obtained.

SCTP and FEC based Loss Recovery Technique for VoIP
M.V.SREERAJ, T.SATYA SAVITRI
Abstract: VoIP (Voice over Internet Protocol) has become one of the most attractive and important applications running and also one of the most emerging technologies in today’s world. Different techniques have been proposed to reduce the packet loss and recover the lost audio data packets during the transmission in the network. In VoIP, Stream Control Transmission Protocol (SCTP) is the responsible for the packet transmission and for the retransmission of the lost data packets. But it does not deal with link errors and consumes large buffer size at the receiver endpoint for estimating the packet loss. In this paper, we propose to design a cross-layer architecture for VoIP networks. In this architecture, Forward Error Correction (FEC) technique is applied in SCTP transmission to ensure the reliability of data transmission. While transmitting VoIP packets, FEC technique gets executed at every intermediate node of the network. When the packets reach the receiver endpoint, the packet loss estimator estimates the packet loss and amount of redundancy to be added in FEC technique. By simulation results, we show that the proposed architecture reduces the packet loss and delay and improves the throughput..

Efficient Mechanisms using ARDUINO to Control Robots
KARTHIK BALASUBRAMANIAN, AROKKIA JERALD PRAVEEN.D, ASWIN CHANDRASEKARAN, NAWIN PRANAV.M.V, KIRAN.R
Abstract: Microcontrollers are used in automatically and autonomously controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems. This paper introduces the controlling of robot using joystick, mobile and laptop using the arduino board. The robot consists of arduino board, an L293D interface circuit and a motor driving system. The controlling devices are connected to the arduino board. The arduino board sends signals to the interfacing board L293D which controls the motor driving system. The robot can also be used as an obstacle avoiding robot and a line follower robot. Using a robot as an obstacle avoider or line follower is made possible simply by using sensors. The sensors used here are proximity sensors. The proximity sensors use variable resistor(s). If the resistance varies the sensor sends different signal to the arduino board and accordingly the robot moves independently. The robot works on combinational logic design and gates.

PAPR Performance of OFDM System Using Modified SLM Approach
D.T.KUSHNURE, S.D.BIRADAR, S.S.MUTTAGI
Abstract: In the era of modern wireless technology Multicarrier communication is one of the more suitable and reliable communication techniques. Orthogonal Frequency Division Multiplexing (OFDM) is used as modulation technique in multicarrier communication. OFDM has numerous advantages over single carrier communication but in spite of the advantages it suffers from one major drawback that is OFDM signal has high Peak Power – to – Average Power ratio (PAPR) . In this paper PAPR performance is simulated using conventional approach of Selective Mapping (SLM) technique and Modified SLM technique for different types of modulation techniques like QPSK, QAM and DPSK. The modified SLM technique is a probabilistic approach to reduce PAPR of OFDM system. This uses Linear Block Code (LBC) that is Extended Hamming Code where the different code having same information and by using selection criteria one of the codes having less PAPR is selected. Modified approach reduces system PAPR to a great extend as well as it reduces cost and complexity of the system. From simulated results it shows that the modified SLM approach is more suitable for practical implementation.

A Novel Theory on Effects of Alternative Potential in Dielectric Polarization
KARTHIK RAJA.K SARAVANAN.R, MOHANVEL.S, RAJA.K, YADHARI.K, SUTHANTHIRA VANITHA.N
Abstract: This paper presents a novel theory on the electronic polarization. The intention is that whenever an alternating potential occurs, a region is developed around it. This phenomenon can be named as Electro Tele Field (ETF). The dipoles are rotated due to the application of alternative voltage. The alternative voltage consists of positive and negative half cycles. During the positive half cycle, dielectric medium is positively polarized, and during the negative half cycle, the medium becomes as a negatively polarized. Hence dipoles get rotated. A continuity tester is able to detect that field. ETF can flow in conductors and penetrate in insulators. This paper explains the effect of alternative voltage on a dielectric. The main application is that the emf can be induced from one coil to another coil without current flow and electromagnetic field.

S.VIVEK K.KISHOR, M.MUTHUMANIKANDAN, G.VIVEK
Abstract: Brushless dc (BLDC) drives have, high efficiency, electromagnetic interference, and high mechanical reliability due to the absence of brushes. They are very suitable for integrated starter alternators in hybrid electric vehicles. This paper discusses about comparison of both PI and fuzzy logic control for a BLDC drive. This control strategy is simple and effective. The advantage of FUZZY logic system is that they do not require any current sensors. This technique can be implemented on a low cost PIC microcontroller. This paper deals about the potential stability issues due to the simplicity of this control under various conditions of load disturbances and also owing to the reduction in processor capability. Lyapunov stability criteria have been used to analyze the closed-loop stability of the system.

Abstract: Every new technology evolved with minimalism as well as stumbling blocks, as the recent innovations and excessive use of power electronic devices such as, fast switching uncontrolled/controlled converters, invertors and cyclo-converters, high voltage power converters used in HVDC etc. make the system flexible to work but also a complex problem of power quality has evolved, the measure of it was voltage and current harmonics, low power factor, reactive power demand etc. Ideally power system network must be electrically clean, harmonics free, balanced, regulated voltage at point of common coupling and must have a unity power factor. In this paper, the analysis of the Series-Shunt Power Quality Compensator (S-SPQC) is presented for three-phase three wire distorted system conditions, in this topology two types of active filter i.e. Series (SAF) and Parallel (PAF) are integrated to accomplish the goal of improving voltage quality by SAF and current quality by PAF. In combined approach of S-SPQC, SAF part is designed by using Synchronous Reference Frame (SRF) technique while PAF part is designed by using Indirect Current Control (ICC) technique. The MATLAB/ Simulink based simulation results are graphically shown as well as tabulated in detail which reflects the performance of the S-SPQC control method discussed in this paper.

Abstract: Topology for closed loop reactive power compensation suitable for dynamic loads using TCR is presented. Firing angle range of TCR is selected in such a way to keep the harmonic content at a minimum level. Simulation results show that the proposed scheme can achieve reactive power compensation in less than a half cycle and the harmonics contents of source are maintained at insignificant levels due to delta connection of TCR and appropriate firing angle range selection of TCR.
