Device Robust-design by Using the Response Surface Methodology

Preferred Robust Response Surface Design with Missing Observations Based on Integrated TOPSIS-AHP Method

- Missing observations occur in experimental designs as a result of insufficient sampling, machine breakdown, high cost, and errors in the measurements. In nanomanufacturing, missing observations often appear in designs because the combination of factors or molecular structures selected by a designer cannot be experimented successfully. In the current paper, Box-Behnken and face-centered compos...

A weighted metric method to optimize multi-response robust problems

In a robust parameter design (RPD) problem, the experimenter is interested to determine the values of con-trol factors such that responses will be robust or insensitive to variability of the noise factors. Response sur-face methodology (RSM) is one of the effective methods that can be employed for this purpose. Since quality of products or processes is usually evaluated through several quality ...

Screening and Optimization of Microextraction of Pb(II) by Inductively Coupled Plasma-Atomic Emission Using Response Surface Methodology

Dispersive liquid–liquid microextraction (DLLME) combined with inductively coupled plasma-atomic emission spectrometry (ICP-AES) was applied for the determination of lead in different environmental water samples. Ammonium pyrrolidine dithiocarbamate (APDC), chloroform and ethanol were used as chelating agent, extraction solvent and disperser solvent, respectively. The effective parameters, such...

Crashworthiness design of multi-cell tapered tubes using response surface methodology

In this article, crashworthiness performance and crushing behavior of tapered structures with four internal reinforcing plates under axial and oblique dynamic loadings have been investigated. These structures have a tapered form with five cross sections of square, hexagonal, octagonal, decagon and circular shape. In the first step, finite element simulations performed in LS-DYNA were validated ...

Design of Dye Adsorption by Amine Terminated Dendritic Functionalized Halloysite Nanotubes Using Response Surface Methodology (RSM)

Thermodynamic Analysis and Statistical Investigation of Effective Parameters for Gas Turbine Cycle using the Response Surface Methodology

In this paper, the statistical analyses are presented to study the thermal efficiency and power output of gas turbine (GT) power plants. For analyzing gas turbine operation and performance, a novel approach is developed utilizing the response surface methodology (RSM) which is based on the central composite design (CCD) method. An attempt is made to study the effect of some operational factors ...
