Improvement in aesthetic look of low grade natural ruby (gemstone) surface was clearly evident after fusion mixture treatment. Surface impurities of the gemstone were significantly reduced to give it a face lift. The processing consists of heat treatment (1000°C) of the raw gemstone with fusion mixture (sodium and potassium carbonates), followed by hydrochloric acid digestion (90°C) and ultrasonic...
In this paper an algorithm for electronic circuit solution using MATLAB is proposed. The given electronic circuit consisting active elements observes the nonlinearity. So first the circuit equations are linearised by converting the active elements e.g Transistors into diodes and other resistive elements by Eber’s-moll model[4]. The resulting linear simultaneous equations are solved for computing the...
Power quality is the major area of research interest amongst scientists. This is because of awareness created by IEEE 519-1992 like standards which implies the utility as well as consumers of electric power to improve the power quality. This paper investigates the potential of multi-pulse converter to be used as power quality solution. Six, twelve, eighteen and twenty four pulse converters have been...
