Abstract The present work aims to carry out a feasible study of wire electro-discharge machining (WEDM) during the Inconel 690 superalloy gears. Processing conditions power-on time, power-off current, and spark-gap voltage are varied evaluate process performance in terms material removal rate (MRR), surface roughness (SR), consumption. Parametric optimization has been carried using combined approach response methodology (RSM) artificial neural network (ANN). Results revealed that ANN...

Material Removal Rate (MRR) is considered as the most desirable process performance measure variable of WEDM process.Variability MRR mainly depends on selected input variables process.The goal current research to improve by optimizing processing parameters.In this experiment, an empirical model was created using following four variables: Power-on time, power-off peak (i p ), and spark-gap voltage.Box-Behnken design (BBD) based response surface methodology (RSM) employed for individual...

Background: Poultry faeces may contain many harmful parasites, which pose significant health risks to the consumer. These parasites then be transmitted man by contaminated soil, drinking water supply or mechanical vectors like flies and rodents. This is a neglected area of public deserves more scientific attention. We explored Scientific literature also assessed our findings. Methods: One hundred (100) poultry samples were for viewing wet mount method. A concentration technique was performed...

A technique for measurement of complex permittivity dielectric materials, using coplanar waveguide (CPW) cells is presented. complete solution the forward and inverse problems, based on a quasi-TEM propagation model, given. Unlike other methods, problem can be solved without use iterative or graphical techniques, by simple matrix inversion. The model accounts various discontinuities along line. Several advantages result from this approach. Measurement over broad frequency range possible,...

Electrochemical honing (ECH) is an encouraging technique of gear finishing because its micro-removal characteristic. In ECH, material removes by combined effect anodic dissolution and mechanical abrasion. It a hybrid micro-finishing process. ECH productive with high accuracy long tool life. However, the lack comprehensive research complex setup design prevents it from being commercialized. This paper discusses emphatic features electrochemical gears; prospective capabilities. A comparative...

Our observations conclusions are provide suggestions government utilize funds better. Statistical Analysis of Accident Risk Factors Optimal Solutions improve understanding causes, consequences, etc., among general...

Parasitic infections of the gut are difficult to detect. It depends on microscopy and also different concentration techniques. All techniques may not be good give reproducible results. Though there some standard solutions giving results but they always affordable in all geographical areas very less able detect parasitic ova both soil faeces. We here report a new technique i.e. sugar-ethanol solution for parasites. In this study we compared our novel (sugar ethanol) with saturated salt by...

Majority of India`s economy is based on Agriculture and it accounts for 18% Gross Domestic Product (GDP).India the largest milk producer ranks second in production world.Even though India first place cattle buffalo population, stands production.One reasons less would be lack knowledge hygienic milking practices among dairy owners milkmen.The objective study to assess extent clean livestock milkmen Singur.Using sample size calculation formula, 100 respondents were interviewed with a pre...

This paper discusses the assistance of pulsating power supply during electrochemical honing (ECH) bevel gears. Experimentation is performed to evaluate effects ECH process parameters: machining time (Tm), pulse-on (Ton), pulse-off (Toff), and duty cycle (Dc) on percentage improvement in surface roughness values, bearing ratio, material removal rate process. A comparative study between continuous DC for gears also executed. It reveals that pulse-assistance generates better quality as compared...
