As the VLSI technology grows up, optimization is required to reduce the complexity, area and power of the digital circuits. In order to optimize the hardware requirement of digital combinational circuits, evolutionary techniques need to be enforced at various levels such as gate level and device level. This paper presents an efficient approach for the optimal design of a combinational logic circuit...
This paper describes the current work of designing a website for learning robotics. It supports the post graduate and senior undergraduate students. It is a drive to cater the requirement of laboratory learning. Both theory and virtual experimental resources are made available. The experiments are in the form of simulation. At this stage of web development, the concepts of mechanisms and kinematics...
The paper introduces a new, simple and direct method of determining the minimum capacitance required for self-excitation of the three phase self excited cage machine. The proposed method is based on the analysis of the complex impedance matrix of the induction generator, when loaded with a general resistive-inductive load (RL). A simple computer algorithm has been developed to predict the minimum...
A voltage controller for the operation of three-phase single switch boost rectifier is proposed using low cost op-amps. The controller automatically adjusts the pulse width of the boost rectifier to maintain a constant dc load voltage of desired level, despite the variations in the load and source voltage. Methods have been proposed for calculating the duty ratio to obtain the desired dc load voltage...
Typical real time computer vision tasks require huge amount of processing power and time for handling real time computer vision applications. Parallel processing founds to be the only solution to obtain the require processing speed for handling high-speed image processing applications. Generally SIMD architecture is suitable under low level processing while MIMD architecture is suitable for high-level...
The aim of our study is the optimization after restoring and reconfigure the faulted area in a distribution network after locating and isolating the faulted block. Restoration involves changing the switch status to maximize the supply to loads that are left unsupplied after fault removal. After system optimization using reconfiguration, Field Programmable Gate Array (FPGA) is used in order to control...
In industries now a day the control of chemical process is important craft. Mostly all the chemical process are highly nonlinear in nature this cause instability of the process. This paper deals with basic simulation studies on of the interactive thermal process. The Combination processes of Continuous stirred tank reactor (CSTR) and heat exchanger were controlled and the mathematical model was developed...
Modern technology has given rise to a slew of forward looking enhancements for systems that transmit and distribute electricity. Distribution networks must be carefully controlled in order to maintain an acceptable power supply quality. In order to meet sustained load demands during varying natural conditions, different renewable energy sources need to be integrated with each other. This paper describes...
A numerical simulation and parametric studies for the separation of air using 5A zeolite for the production of oxygen are presented for a basic two bed pressure swing adsorption (PSA) process. The simulation is based on an in-house program 'PSASOL' developed in MATLABŽ. The transient process of PSA has been described by a set of partial differential equations, which were solved using a finite difference...
There are available several watermarking techniques used for data security. Digital media normally assures fairly high quality, nevertheless can be easily reproduced in a perfect form. This perfect reproducibility takes an advantage from certain point of view, while it produces an essential disadvantage, since digital media is frequently copied illegally. A solution of this problem is to embed digital...
In this paper, voice signal compression (VSC) is a technique that is used to convert the voice signal into encoded form and when compression is required, it can be decoded at the closest approximation value of the original signal. This work present a new algorithm to compress voice signals by using an ldquoadaptive wavelet packet decomposition and psychoacoustic modelrdquo. The main goals of this...
In this paper, voice signal compression and spectrum analysis (VSCSA) is a technique that is used to compress transparent high quality voice signals upto 45% - 60% of the source file at low bit rate 45 kbps with same extension (i.e. .wav to .wav), then voice spectrum analysis (VSA) is started. Voice signal compression (VSC) is done by using adaptive wavelet packet a tool of MatLab for decomposition...
