In this paper an improved power quality buck-boost converter fed permanent magnet brush less DC motor (PMBLDCM) drive is employed for adjustable speed operation of PMBLDCM. A single-phase, single-switch AC-DC converter topology based on non-isolated buck-boost converter is employed for power factor correction (PFC) and operated with voltage follower control in discontinuous conduction mode (DCM) operation for sensor reduction. This PFC controller ensures near unity power factor in wide speed range of the drive while restricting the total harmonic distortion (THD) in AC mains current within the specified limits of the IEC standard. The proposed control scheme with PFC converter based PMBLDCM drive is designed, modeled and simulated in Matlab-Simulink environment for an air conditioner compressor driven through a 2 kW, 5.2 Nm PMBLDC motor. The obtained results are presented to validate the effectiveness of the proposed control scheme for power quality improvement at AC mains.

In emerging electric power systems, due to increased loading or due to severe contingencies often lead to situation where system no longer remains in the secure operating region. Under these situations, it is primary objective of the operator to apply control action to bring the power system into the secure region. FACTS devices can play a very important role in power system security enhancement. Due to high capital investment, it is necessary to locate these devices optimally in the power system. In this paper, a real power flow performance index (PI) sensitivity based approach and the line outage distribution factor has been proposed to decide optimal location of Thyristor Controlled Series Compensator (TCSC) and Static Synchronous Series Compensator (SSSC) to enhance the security of the power system. The effectiveness of the proposed controller has been tested on modified IEEE 30 bus system using Power World Simulator Software Version 12.0.

CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a computer-generated test that humans can pass but current computer systems cannot. CAPTCHA provide a method for automatically distinguishing a human from a computer program, and therefore can protect Web services from abuse by so-called bots. Most CAPTCHA consist of distorted images, usually text, for which a user must provide some description. Unfortunately, visual CAPTCHA limit access to the millions of visually impaired people using the Web. The Audio/Voice based CAPTCHA was created to solve this accessibility issue, however, the security of Audio based CAPTCHA was never formally tested. Some Visual CAPTCHA have been broken using machine learning techniques, and we propose using similar ideas to test the security of Audio based CAPTCHA. Audio-based CAPTCHA is generally composed of a set of words to be identified, layered on top of noise. To analyze the security of CAPTCHA it is essential to break it. This breaking of Audio based CAPTCHA has two steps first remove noise and then convert it to text. This paper addresses algorithm for adaptive noise reduction from Audio based CAPTCHA and thus in turn help to determine strength of CAPTCHA. The result shows accuracy up to 80% for Audio based CAPTCHA taken from popular Web sites. Such accuracy is enough to consider these CAPTCHA can be broken after converting to Text form.

Virtual instrumentation is the use of customizable software and modular measurement hardware to create user-defined measurement systems, called virtual instruments. This paper presents multitasking using parallelism process of multi-core system. Multitasking is one of the simplest ways to distribute workload in a multi-core system, since the operating system does most of the work. This paper addressed the software support for such system using National Instruments Lab view environment. The design consists of comparator for various controller used in vehicular system. These new highly parallel architectures contain a relatively large number of programmable cores, each approaching the complexity of a traditional microprocessor.

Design of CMOS limiting amplifier and Received signal strength indicator presents the analysis and the optimization of a limiting amplifier with received signal strength indicator realized in a standard technique of CMOS process. The limiter works at a supply voltage of 2.0V and at a frequency of 10.7 MHz.. The optimal power consumption for specified speed, overall gain, and accuracy is determined by the limiting amplifier and RSSI. The offset subtract or is used to reduce the offset which is arise due to the cross connected source coupled pair. Also the FWR is used for current rectification and summation in the RSSI. The RSSI stages rectify the signals from each stage and change the signal to a current. The output of each stage of the RSSI are fed to a resistor to ground, which performs a summing operation. Furthermore various simulation methods are used in order to guarantee the functionality of the circuit under all conditions of work.

Architecture of a mixed mode fuzzy controller for Integrated MEMS System is designed. The architecture needs no A/D or D/A converters. The fuzzification and defuzzification are implemented in analog technique, while the inference unit operates digital. So the advantages of analog (e.g. small chip area, fast and low number of wires) and digital (e.g. programmable and sequential processing) can be used. The new idea of this architecture is to use pointers instead of the analog values. So it is possible to use a digital inference unit and the analog signals will he switched directly from the fuzzification unit to the defuzzification unit without distortion by the inference unit. We used 4 membership functions for each of the 4 inputs and 4 singletons for the output. The degree of overlap of the membership functions is limited to 2 inputs.

Microgrid is a grid which helps to provide the generation in case of Grid failure. Microgrid is a new concept in the arena of green power generation, which is substantially attracting many researchers' interest due to its potential to extend the applications of the distributed generations, especially the renewable energy. Microgrid is a low voltage electrical network with small distributed generators, energy storage devices, controllable loads & protection. A MicroGrid can increase the reliability of energy supplies by disconnecting from the grid in the case of network faults or reduced power quality models for the main microsources/non conventional energy sources including Wind Turbines, Diesel Generator and fuel cells are properly established, in addition to the basic models of the power electronics interfaces being given simultaneously. This project emphasizes modelling & simulation of a Microgrid to account for both the transient and steady-state system characteristics; MATLAB/Simulink is used for the simulation, which can simulate both the steady and dynamic characteristics of the three-phase Microgrid. The result shows that there is an increase in power generation when the microsources/ non conventional energy sources connected within Microgrid which helps in different applications and also in case of grid islanded mode.
