Now a days the power system structure is growing continuously. So the reliability has become a big task for the protection engineers. This paper presents a fast and accurate fault detection technique which is very much useful for reliable operation of the power systems. To achieve fastness and reliable operation various new technologies have been used but out of all the available equipment the use...
In this paper we preset implementation of an optimized Sobel edge detection algorithm on FPGA. The optimized gradient based edge detection method reduces the area up to 48.76% compared to existing gradient calculation unit, and also reduces propagation delay up to 51% compared to the area optimized architecture. The entire project is implemented on Spatran-3E FPGA board. VGA interface is used to display...
Background The present study aims to assess the knowledge and attitude about needle stick injuries and sharps disposal. Methods A self designed questionnaire of 15 questions was handed out to 200 participants including undergraduate students (group 1), postgraduate students (group 2), faculty members (group 3) and auxiliary staff members (group 4). The data was collected and analyzed using Chi square...
Harmonics are voltages and currents which have frequency components that are integers multiple of the fundamental frequency - polluting the pure sinusoidal waveform. This paper deals with basics of harmonics, causes that generate harmonics and Estimation of power quality measurements such as individual harmonic distortion, %Total Harmonic Distortion (THD), RMS and Peak-to-peak values using tool LAB...
