artificial neural networks (anns) are computer techniques that attempt to simulate the functionality and decision-making processes of the human brain. in the past few decades, artificial neural networks (anns) have been extensively used in a wide range of engineering applications. there are only a few applications in liquid membrane process. the objective of this research was to develop artific...

in this study, the application of gray relational analysis (gra) and taguchi method in multi-criteria process parameters selection of turning operation has been investigated. the process responses under study are material removal rate (mrr) and surface roughness (sr); in turn, the input parameters include cutting speed, feed rate, depth of cut and nose radius of the cutting tool. the proposed a...

In this research work the tool-chip interface temperature is measured experimentally during turning of EN-31 steel alloy with tungsten carbide inserts using a tool-work thermocouple technique. First and secondorder mathematical models are developed in terms of machining parameters by using the response surface methodology on the basis of the experimental results. The results are analyzed statis...

the aim of this study was to investigate the effects seaweeds gracilariopsis persica in diets on performance and tsh, t3 and t4 hormones in serum of laying quail. a total of 112 laying quails were randomly allocated into four dietary treatments (diets containing 0, 1, 3 and 5% seaweed) with 4 replicates of 7 birds each. the birds were fed on experimental diets for 12 weeks. eggs were collected ...

Abstract The change in water flow required at the BFP pump Barru Power Plant is only regulated by a valve located on pressure side, causing excess power consumption and its own consumption. One effort to save energy usage make frequency adjustments that refer right flow. To determine effect of expected pressure, simulation inverter modeling performed using SPWM switching method based affinity l...

Intelligent knowledge based system (IKBS) is developed for optimizing dry CNC turning process using Taguchi method, CNC Machine, EN19 steel as the work piece material, andCutting Insert. Tool wear and spindle loading which are the machining parameters, spindle speed, feed rate, and depth of cut, areoptimized through the intelligent knowledge based system (IKBS). The experimental CNC turning mac...

Aquantitative relationship is demonstrated between the coefficient of static friction and the milling process parameters. Different levels of surface roughness are obtained by varying the spindle speed, depth of cut and feed which is followed by measurement of surface roughness using stylus profile meter. The corresponding coefficients of static friction are measured for all specimens using inc...
