Power quality of the system will be affected due to the increasing use of power electronic equipment and nonlinear loads. Active Power Filters (APF’s) are effective in mitigating line current harmonics and can improve the power quality. In this paper, instantaneous active and reactive power (p-q) theory is employed to generate the reference currents and ...

The rapid growth of technology and infrastructure has made the peoples’ lives easier. The advent of technology has also increased the traffic hazards and the road accidents take place frequently which causes huge loss of life and property because of the poor emergency facilities. The authors’ project will provide an optimum solution to this draw ...

In this paper, the authors proposed a portable wireless device which will enable a person to write on white board from distance. The hand held device consists of a touchpad, microcontroller, wireless transmitter and battery. The touch pad is interfaced with the microcontroller with the help of touch screen controller. The co-ordinates are sent to ...

In this paper the authors give a novel idea about the design and implementation of a microcontroller based pulse counter. Intel 8051 is used as the main microcontroller unit and the system has been fabricated to count the total number of pulse in a minute. IR sensors are connected as the input sensors which read ...

In this paper, the authors monitor and control the PLC based system using wireless technology. In this paper, they are going to use a ZIGBEE and SCADA technology to get wireless automation system. Pair of ZIGBEE is used here, among that one is connected with the PLC in the industry side and another one is ...

In this paper, the authors describe an approach of isolated speech recognition by using the Mel-scale Frequency Cepstral Coefficients (MFCCs) and Dynamic Time Warping (DTW). Several features are extracted from speech signal of spoken words. An experimental database of total five speakers, speaking 10 digits each is collected under acoustically controlled room is taken. MFCC ...

Binary division is basically a procedure to determine how many times the divisor D divides the dividend B thus resulting in the quotient Q. At each step in the process the divisor D either divides B into a group of bits or it does not. The divisor divides a group of bits when the divisor ...

Performance evaluation of Proportional-Integral-Derivative (PID) controllers implemented with a clear objective to control the temperature of a ventilation system is the focal point of this paper. Mathematical models of plant (chamber) and actuator were developed. Controller design based on the models was also developed using Simulink. The models were validated through simulation using Matlab/Simulink and ...

Today, wireless technology has reached a point that has no choice other than using only one compact and multiband antenna to simultaneously answer all the demands of users at different frequencies. A fractal antenna is created by repeating a motif over two or more scale sizes, or “Iterations”. For this reason, fractal antennas are very ...

A 2-bit booth encoder with Josephson Transmission Lines (JTLs) and Passive Transmission Lines (PTLs) is designed. The booth encoding method is one of the algorithms to obtain partial products. With this method, the number of partial products decreases down to the half compared to the AND array method. The circuit area of the multiplier designed ...
