The variation of the breakdown voltage of a low frequency electrical pulsed discharge due to an external electrode is reported. The discharge tube consists of a thin glass tube having two internal hollow electrodes. A thin copper foil wrapped around the glass tube forms the external electrode. The internal electrodes of the discharge tube are supplied by a flyback converter. Its operating point...

In this work the isothermal transition from bubbling to jetting regime in a bottom blown Peirce-Smith copper converter is numerically studied, varying the air jet injection velocity from 5 to 100 m s -1 . Large Eddy Simulation turbulence model is employed in the computer simulations to obtain transient, rather than averaged, phase distributions. For low injection velocities the bubbling regime ...

This paper presents selected design and operation details of a custom integrated neural chip. This neural processing chip is designed in the recent 0.18 μm, single poly, six-layer Copper Interconnect Technology. The chip realizes an architecture that achieves the task of autonomous-learning execution times in micro to milli seconds. The core consists of basic building blocks of 4-quadrant multi...

This paper develops an operator guidance system for an industrial process which involves scheduling ideas from manufacturing systems. The industrial process under study is the converter aisle in a copper smelter. Our objective is to increase throughput by improving utilization of the smelter’s resources. This paper partly addresses this objective by applying scheduling techniques to optimize th...

The major pollutants emitted from spark ignition (SI) engine are carbon monoxide (CO) and unburnt hydrocarbons, nitrogen oxides which are hazardous to human beings and environment. If the engine is run with alcohol blended alternate fuels, aldehydes are emitted as significant pollutants, which are carcinogenic and harmful in nature. Hence, control of these aldehyde emissions call for immediate ...

A novel approach is proposed for a high step-up and high efficiency converters with a low switch stress. The integrated boost-flyback converter uses coupled-inductor techniques to achieve high step-up voltage with low duty ratio, and thus the slope compensation circuit is disregarded. The proposed circuit topology improving highgain ratio, increasing efficiency, reducing the secondary side of c...

In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...
