In this paper, the application of D-optimal models, as an alternative to response surface models (RS models) for design of experiment (DOE) was examined. Two D-optimal models for tilt-rotors in the wind tunnel experiment, as a form of quadratic functions, were generated based on a chosen optimality criterion. This optimality criterion was used to generate the optimized sampled points in the des...

The problem with computer model calibration by tuning the parameters associated models is significant in many engineering and scientific applications. Although several methods have been established to estimate parameters, research focusing on design of remains limited. Therefore, this paper proposes a sequential experiment based D-optimal criterion, which can efficiently tune while improving pr...

this study concerns the scope to improve water flooding in heterogeneous reservoirs. we used an existing, in-house developed, optimization program consisting of a reservoir simulator in combination with an adjoint-based optimal control algorithm. in particular we aimed to examine the scope for optimization in a two-dimensional horizontal reservoir containing a single high permeable streak, as a...

Background and Objectives: Oils used in frying should include special characteristics such as high oxidative stability, prolonged shelf life, low price, abundance and availability and desirable flavors. Nowadays, consumers are further interested in low saturated frying oils.  Recently, manufacturers focus on eliminating palm oil derivatives (as a major vegetable source of saturation) from fryin...

Microwave pyrolysis of finely ground jatropha seed biochar was used as bio-filler to develop biocomposites. Effects influencing the mechanical properties biocomposites were investigated based on varied material ratio. Ratios by percentage weight determined D-optimal (custom) mixture design using Stat Ease “Design Expert”. The properties, such tensile strength, modulus elasticity, and microhardn...

The aim of this work is in the formulation a dietary supplement, combining spirulina and date stone benefits. For this, study was done on these two ingredients by determining their approximate composition antioxidant potential. Following we used statistical method to determine appropriate proportions obtain tablet with optimal physical properties. After setting parameters, analysed tablet’s eff...
