Staggered-Level Designs for Response Surface Modeling

An Algorithmic Construction of Four-Level Response Surface Designs

Response surface methodology is widely used for developing, improving and optimizing processes in various fields. In this paper we present a method for constructing four-level design matrices in order to explore and optimize response surfaces where the predictor variables are each at four equally spaced levels, by utilizing a genetic algorithm. The produced designs achieve both properties of ne...

Blocking response surface designs

The design of experiments involving more than one blocking factor and quantitative explanatory variables is discussed, the focus being on two key aspects of blocked response surface designs: optimality and orthogonality. First, conditions for orthogonally blocked experiments are derived. Next, an algorithmic approach to computeD-optimal designs is presented. Finally, the relationships between d...

Some Guidelines For Using Nonparametric Methods For Modeling Data From Response Surface Designs

Optimal Designs of Staggered Dean Vortex Micromixers

A novel parallel laminar micromixer with a two-dimensional staggered Dean Vortex micromixer is optimized and fabricated in our study. Dean vortices induced by centrifugal forces in curved rectangular channels cause fluids to produce secondary flows. The split-and-recombination (SAR) structures of the flow channels and the impinging effects result in the reduction of the diffusion distance of tw...
