This paper deals with a proposal for joint modeling and process optimization split-plot designs analyzed through mixed response surface models. It addresses the following main issues: i) building of responsesurface model multiple situation, by defining only one which specific coefficients areincluded studying association among responses; ii) considering fixed as well random effects within conte...

The conventional process of machining nitinol alloy which possesses excess strain hardening and low thermal conductivity makes a complex that leads to extensive wear on the tool inadequate surface quality. Wire-electro-discharge (WEDM) is widely accepted for this involving various input factors, namely, P (pulse-on-duration), Q (pulse-off-duration), C, (maximum-current), V (voltage). Using PSO ...

The influence of extraction temperature, powder concentration, and extraction time on the antioxidant properties of aqueous ginger extract was investigated. The possibility of estimating the antioxidant properties of the extract from its absorbance and colour properties was also investigated. Results indicated that powder concentration was the most significant factor to consider in optimizing a...

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...
