A demonstration of the utility of fractional experimental design for finding optimal genetic algorithm parameter settings [PDF]

open access: yes, 2004
This paper demonstrates that the use of sparse experimental design in the development of the structure for genetic algorithms, and hence other computer programs, is a particularly effective and efficient strategy.

Indicator function and complex coding for mixed fractional factorial designs

open access: yes, 2007
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 ...

Minimal average degree aberration and the state polytope for experimental designs [PDF]

open access: yes, 2008
For a particular experimental design, there is interest in finding which polynomial models can be identified in the usual regression set up. The algebraic methods based on Groebner bases provide a systematic way of doing this.

PREPARATION OF TiO2/PERLITE COMPOSITES BY USING 23-1 FRACTIONAL FACTORIAL DESIGN

open access: yesJournal of the Turkish Chemical Society, Section A: Chemistry, 2016
Successive impregnation and calcination process was performed in order to produce TiO2/perlite composites. 23-1 fractional factorial design was first applied to optimize the production conditions of TiO2/perlite photocatalysts.

Modelling multi-tier enterprise applications behaviour with design of experiments technique [PDF]

open access: yes, 2015
Queueing network models are commonly used for performance modelling. However, through application development stage analytical models might not be able to continuously reflect performance, for example due to performance bugs or minor changes in the ...

Efficiency Improvements of Antenna Optimization Using Orthogonal Fractional Experiments

open access: yesInternational Journal of Antennas and Propagation, 2015
This paper presents an extremely efficient method for antenna design and optimization. Traditionally, antenna optimization relies on nature-inspired heuristic algorithms, which are time-consuming due to their blind-search nature.

Optimized polymer flooding projects via combination of experimental design and reservoir simulation

open access: yesPetroleum, 2017
The conventional approach for an EOR process is to compare the reservoir properties with those of successful worldwide projects. However, some proper cases may be neglected due to the lack of reliable data.
