CONSTRUCTION OF ASYMMETRICAL RESPONSE SURFACE DESIGNS

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...

Asymmetrical membranes and surface tension.

The (31)P-nuclear magnetic resonance chemical shift of phosphatidic acid in a membrane is sensitive to the lipid head group packing and can report qualitatively on membrane lateral compression near the aqueous interface. We have used high-resolution (31)P-nuclear magnetic resonance to evaluate the lateral compression on each side of asymmetrical lipid vesicles. When monooleoylphosphatidylcholin...
