The ethanol, methanol and acetone extracts of Aloe vera gel were studied for their antimicrobial activity against four Gram-positive and Gram-negative bacteria using agar well diffusion method. The extracts showed varied levels of antimicrobial activity against the tested pathogens. The ethanol and methanol extracts showed higher activity while acetone(More)
In this paper, a synchronous cuk converter proposed for analyzing the performance of photovoltaic system is presented. In the proposed cuk converter, the conduction losses and switching losses are reduced. The conduction losses are reduced by replacing the diode with MOSFET and the switching losses are reduced by providing an auxiliary circuit. The proposed(More)
Problem statement: The phenomenon of flashover in polluted insulators has been continued by the study of the characteristics of contaminating layers deposited on the surface of insulators in high voltage laboratories. In the literature, Experimental investigations have been carried out on a real insulator or a flat plate model of insulators under high(More)
A testable design with a universal test set for single stuck-at zero and stuck-at one faults of Reed-Muller canonical form of Exclusive-OR sum of product logic expressions is proposed. The test circuit detects almost all the single stuck-at faults and needs only simple modifications for variations in the circuit under test. The number of test vectors is(More)
In view to provide continuous services for passengers, mobility management plays a major role in Vehicular Ad hoc Networks (VANETs). As Network Mobility (NEMO) is known for its high mobility, it becomes extremely suitable for VANETs. The vision for VANETs is road safety and aimed for efficiently dealing the mobility of a set of mobile nodes using Mobile(More)
The three day conference on Antimicrobial Resistance: A Cause for Global Concern was organized from 6-8th February, 2012 by the Department of Microbiology and Fermentation Technology, Sam Higginbottom Institute of Agriculture, Technology and Sciences (SHIATS) [Deemed-to-be-University], Allahabad, India. The conference received an overwhelming response from(More)
Vehicular Ad-Hoc Networks [VANET] is one of the fastest emerging technologies for research as there are many issues and challenges to be addressed by the researchers before the technology becomes commercialized. The challenges in VANET are, designing suitable routing protocols appropriate to the traffic model, providing security of the data and emergency(More)
This study presents a novel method of detection of inter turn shorts based on k means clustering technique. In addition to inter turn short detection, the other faults like open, short, phase to phase faults and DC voltage faults are detected through wavelet transforms and k means clustering. Open and short faults are classified using artificial neural(More)
