Abstract This study aimed to obtain the optimum formula of Chlorella milk with D-Optimal Mixture Design and determine consumer preference for formula. research method was divided into formulation response design, hedonic test, analysis, optimization, verification The determined based on highest score taste. Two solutions were obtained, it found that 0.40% + 0.05% vanillin 4.55% sugar most prefe...

Paper aims Frequently, researchers try to find a better way allocate assets in order have maximum return and low variability portfolio as diverse possible. This paper apply D-Optimal Design the context of Mixture optimization efficiently select runs proposed experimental design. Originality A new approach optimal weights that maximize returns minimize risk using was used. multi-response problem...

reactivity controlled compression ignition (rcci) is a novel combustion concept which uses port fuel injection (pfi) of a low reactivity fuel and direct injection (di) of a high reactivity fuel with optimum multiple injection to provide a stratified mixture inside the combustion chamber. piston bowl design has a considerable effect on engine’s pollutant emissions specially unburned hydrocarbons...

Traditional factorial designs for evaluating interactions among chemicals in a mixture may be prohibitive when the number of chemicals is large. Using a mixture of chemicals with a fixed ratio (mixture ray) results in an economical design that allows estimation of additivity or nonadditive interaction for a mixture of interest. This methodology is extended easily to a mixture with a large numbe...

In this paper we propose a new method, based on the conditional distribution method in Monte-Carlo methods, to generate the uniform distribution on the domain T n (a; b) = f(x 1 ; ; x n) : 0 a i x i b i 1; 0 i n; x 1 + + x n = 1g, where a = (a 1 ; ; a n) and b = (b 1 ; ; b n). By this new method we can easily obtain uniform designs of experiments with mixtures, i.e., to generate a set of points...

The influence of full-fat soy flour (FFSF) and extrusion conditions on the mechanical characteristics of dry spaghetti were evaluated. Process was performed with screw speed of 10-40rpm and water circulating temperature of 35-70°C. Data analysis using mixture design showed that this enrichment resulted in significant differences in mechanical strength. Keywords—Pasta, Mixture design, Enrichment...

In adaptive optimal procedures, the design at each stage is an estimate of the optimal design based on all previous data. Asymptotics for regular models with fixed number of stages are straightforward if one assumes the sample size of each stage goes to infinity with the overall sample size. However, it is not uncommon for a small pilot study of fixed size to be followed by a much larger experi...

An improved approach for computing the confidence regions for the optimal factor settings obtained from optimizing a general response surface model is presented. The approach has a better computational efficiency and improved accuracy compared to existing methodology. A three-factor mixture experiment was used for the performance comparison. The coverage rate properties of the resulting confide...
