Indicator function and complex coding for mixed fractional factorial designs [PDF]
In a general fractional factorial design, the $n$-levels of a factor are coded by the $n$-th roots of the unity. This device allows a full generalization to mixed-level designs of the theory of the polynomial indicator function which has already been ...

Two-by-Two Factorial Design [PDF]
•In simulation research, we are often interested in comparing the effects of more than one independent variable.•Factorial designs allow investigators to efficiently compare multiple independent variables (also known as factors).•An example and resources are described for using a two by two factorial design in simulation research.

A Study For Efficiently Solving Optimisation Problems With An Increasing Number Of Design Variables [PDF]
Coupling optimisation algorithms to Finite Element Methods (FEM) is a very promising way to achieve optimal metal forming processes. However, many optimisation algorithms exist and it is not clear which of these algorithms to use. This paper investigates

The AVS is defined operationally as acid volatile sulfide, which is a controlling phase on the partition of some metallic species in sediments. A Factorial design was evaluated by means of 16 experiments and using four variables: temperature, extraction ...

Optimizing mating schemes in fish breeding [PDF]
The optimal contribution selection method and the simulated annealing algorithm were used to maximize the genetic gain and reduce inbreeding in fish breeding populations.

The results suggest that the two variables studied are significant and that they may be independently optimized. The material of the sample holder interferes with the incineration process only due to the amount of heat transfered.

Factorial design-assisted spectroscopic determination of oxybutynin hydrochloride
In this study, we have developed two facile spectroscopic methods for quantifying oxybutynin (OBT) hydrochloride in its pure form and tablets using design of experiments (DOEs). The spectroscopic methods depended on the ion-pair complex formation between
