Electrical discharge machining (EDM) technique has been widely used in modern metal working industry for producing complex cavities in dies and moulds, which are otherwise difficult to create by conventional machining. The process has the advantage of being able to machine hardened tool steels. However, its low machining efficiency and poor surface

This paper develops a single order mathematical model for correlating the various electrical discharge machining (EDM) parameters and performance characteristics utilizing relevant experimental data as obtained through experimentation. Besides the effect of the peak ampere, pulse on time and pulse off time on surface roughness has been investigated

The rapid expansIOn of motor vehicle in globally dedicates the increase of energy demand in an acceleration fashion. If driving habits remain unchanged, car will have to become nearly three times more energy-efficient by 2030 just to maintain that sector's present consumption. If energy use trends are projected to year 2100, transportation woul

A solar assisted heat pump dryer has been designed, fabricated and tested. This paper presents the performance of evaporator-collector and air collector, when operated under same meteorological conditions. ASHRAE standard procedure of collector testing has been followed. The absorber platce of the evaporator-collector is made of copper plate painte

The Advanced Theory of Peat vehicle has been written with emphasizing the fundamental engineering principles underlying the determination of the mechanical properties of peat terrain, developing simulation models for optimizing the vehicle design parameters, the rational design and development non guided vehicle more accurately in order to control

Zinc (Zn), after iron, is the second most abundant essential element in different organs of the human body. The amount of Zn to be absorbed and hence utilized or metabolized in different tissues depends on the total Zn content of the diet and its bioavailability, specially its solubility in the intestinal lumen. In the brain, additional control on

The integration of the teachings of Islam in many fields of studies such as physics, chemistry, mathematics, engineering, and molecular biology is perceived by many to be easier said than done. However, it is necessary to caution that taking teachings from Islamic guidelines and integrating them to the context of scientific evidence or vice versa p

Intelligent air-cushion tracked vehicle (IACTV) is focused for the alternatives to conventional off-road vehicles, which are driven by track system and air-cushion system. To make IACTV as efficient as possible, proper investigation of vehicle performance is essential. However, most relevant factors that affect the competitive efficiency of the air

The main focus of this study is to develop a fuel efficient hybrid engine to operate a designed and developed urban car of weight 1.42 kN. The hybrid engine is developed by coupling a high efficient 12 volt generator with a 33.5 cc engine of power 1.18 kW @7,000 rpm. The generator starts to power the DC motor to propel the car as soon as the engine

This study presents an automated traction control system (ATCS)without incorporating the function of hydraulic system. The ATCS is used for improving the vehicle performance in terms of stability and torque or speed needed in order to produce smooth driving. Driving motor and wheel speed sensor (WSS) with RPM meter are used in this study to develop
