This paper discusses the experimental investigation to find out the optimal electrolyte composition in improving the surface quality of the gear teeth profile during surfacing finishing of bevel gears by the electrochemical honing process. In this study, AISI 1040 was used as the workpiece material, mixtures of sodium chloride and sodium nitrate in different ratios were used as the input parame...

We propose and develop a genetic algorithm (GA) for generating D-optimal designs where the experimental region is an irregularly shaped polyhedral region. Our approach does not require selection of points from a user-defined candidate set of mixtures and allows movement through a continuous region that includes highly constrained mixture regions. This approach is useful in situations where extr...

The objective of the current study was to develop and optimize a sublingual tablet formulation of captopril which is an effective drug in the treatment of hypertension. Captopril containing tablets were prepared by direct compression method using different ingredients such as polyvinyl pyrrolidone, starch 1500, sodium starch glycolate and lactose (independent variables) and magnesium stearate, ...

oil in water emulsions have attracted considerable attention in food industry due to their large applications. in this study, the effect of thermal treatment on oil in water emulsions (o/w) containing 40% oil was studied. the emulsions were prepared using xanthan gum, guar gum and carboxymethyl cellulose as stabilizer and polyoxyethylen sorbitan monooleat as emulsifier. a mixture design was use...

Computer experiments often have inputs that are proportions/fractions of components in a mixture. In these mixture computer experiments, it can be of interest to perform robust and tolerance design on the mixture proportions since the proportions are subjected to noise variations. Traditionally, manufacturing of mixture products is controlled via interval tolerances for mixture amounts. In this...

Food fortification is an effective intervention strategy for combating micronutrient deficiencies. Vitamin A can be fortified in a wide range of food vehicles. In this research work, vitamin the form palmitate (VAP) have been microencapsulated by emulsion technology intended purposes. D-optimal mixture design approach was applied optimizing experimental process parameters. Detailed physico-chem...
