for all industrial processes, modelling, optimisation and control are the keys to enhance productivity and ensure product quality. in the current study, the optimization of process parameters for improving the conversion of isoeugenol to vanillin by psychrobacter sp. csw4 was investigated by means of taguchi approach and box-behnken statistical design under resting cell conditions. taguchi desi...

Optimization for enhanced phytase production by Aspergillus oryzae SBS50 in submerged fermentation was investigated using Taguchi design. In first step design, starch, beef extract, magnesium sulphate, ferrous sulphate and Tween 80 were identified as significant factors affecting phytase production. These significant factors were further optimized at four different levels using a second Taguchi...

Parametric design optimization of an automotive body crashworthiness improvement is presented. The thicknesses of parts are employed as design variables for optimization whose objective is to increase the maximum deceleration value of the vehicle center of gravity during an impact. Using the Taguchi method, this study analyzes the optimum conditions for design objectives and the impact factors ...

In the present study, a comparison of central composite design (CCD) and Taguchi method was established for Fenton oxidation. [Dye]ini, Dye:Fe(+2), H2O2:Fe(+2), and pH were identified control variables while COD and decolorization efficiency were selected responses. L 9 orthogonal array and face-centered CCD were used for the experimental design. Maximum 99% decolorization and 80% COD removal e...

BACKGROUND: The control of proliferation, differentiation and survival of normal and malignant cells in the tumour microenvironment is under the control of a wide range of different factors, including cell:cell interactions, cytokines, growth factors and hormonal influences. However, the ways in which these factors interact are poorly understood. In order to compare the effects of multiple vari...

a series of experiments were designed to utilize the taguchi method for investigating the effects of important parameters on the synthesis of nax zeolite and to find the best conditions of synthesis. an l9 orthogonal design of taguchi approach was applied to design experiments consisting of 9 trails. the effect of molar composition, including sio2/al2o3 and na2o/al2o3 ratios, and the crystalliz...

Identification of significant process parameters using experiments needs to be carefully formulated as it can be a resource demanding process. Using appropriate statistical techniques such as the Taguchi method of factorial design of experiments, the number of necessary experiments can be reduced and the statistical significance of parameters can be safely identified. In the case of linear fric...

In this work, the solubility of nicotine extracted from tobacco leaves, found in the north of Iran, in supercritical carbon dioxide has been measured. Also the effects of pressure, temperature, extraction dynamic time, and the organic co-Solvent on the amount of nicotine extracted from tobacco leaves have been investigated. It should be stressed that in order to reduce significantly the num...

The objective of the Taguchi parameter design is to improve the performance of a product or a process by determining the levels of its design parameters such that the performance characteristic is robust against various causes of variation. Parameter design problems are broadly classified into static and dynamic ones. Static problems are further classified into the-nominal-thebest, the-larger-t...

This paper presents an application of the Taguchi method parameter design to optimize the surface roughness, tool wear and cutting force by hard turning process. The Taguchi parameter design method is an efficient method in which response variable can be optimized, given various controls and using fewer experimental runs. Hard turning is the latest trend in all manufacturing industries and it i...
