The quality of manufactured products is characterized by many controllable quality factors. These factors should be optimized to reach high quality products. In this paper we try to find the controllable factor’s levels with minimum deviation from their target and with a least variation. To solve such problems a simple aggregation function is used to aggregate the multiple response functions fo...

This work aims at studying the optimization of microwave-assisted extraction (MAE) and pressurized liquid extraction (PLE) by multi-response surface methodology (RSM) to test their efficiency towards the extraction of phenolic compounds from Moringa oleifera (M. oleifera) leaves. The extraction yield, total phenolic content (TPC), total flavonoid content (TF), DPPH scavenging method and trolox ...

gelatin is a protein hydrocolloid. because of its unique characteristics such as gel forming, thickening, stabilizing, emulsifiing, foam and film forming, is widely used in food industries. in this research, in order to optimize the factors which affect enzymatic extraction method of gelatin ,the effects of three variables, enzyme concentrations(2-10 ppm), time(8-16 hours) and temperature(60-80...

Ti-6Al-4V is an alloy that has a high strength-to-weight ratio. It known as alpha-beta titanium with excellent corrosion resistance. This wide range of applications, e.g., in the aerospace and biomedical industries. Examples alpha stabilizers are aluminum, oxygen, nitrogen, carbon, which added to titanium. beta titanium–iron, titanium–chromium, titanium–manganese. Despite exceptional properties...

Excess Pb (II) concentrations in wastewater have raised concerns of a risk to health and the environment due their toxicity. This has contributed need for sustainable technology remove heavy metals from wastewater. Biosorption provides potential contribution solution. study proposes cost-effective method lead ions through use activated carbon vine shoots as biosorbent. However, economic cost en...

this paper presents a hybrid method for the optimization of forging process of an aerofoil blade. preform shape and die parting-line angle are optimized in order to minimize the volume of the unfilled die cavity, material waste, forging forces. the overall optimization scheme used in this research work includes a multi-objective approach that is combination of response surface and finite elemen...
