Optimization of MCM-48 synthesis using factorial design
CerâmicaMCM-48 mesoporous materials were hydrothermally synthesized according to the 22 factorial design by varying the crystallization time and temperature of the synthesis gel, and characterized by means of X-ray diffraction analysis and adsorption of N2.

Resource Optimized Quantum Architectures for Surface Code Implementations of Magic-State Distillation [PDF]
, 2019 Quantum computers capable of solving classically intractable problems are under construction, and intermediate-scale devices are approaching completion. Current efforts to design large-scale devices require allocating immense resources to error correction, with the majority dedicated to the production of high-fidelity ancillary states known as magic ...

Geometric isomorphism and minimum aberration for factorial designs with quantitative factors [PDF]
Annals of Statistics 2004, Vol. 32, No. 5, 2168-2185, 2005 Factorial designs have broad applications in agricultural, engineering and scientific studies. In constructing and studying properties of factorial designs, traditional design theory treats all factors as nominal. However, this is not appropriate for experiments that involve quantitative factors. For designs with quantitative factors, level permutation

Forward selection and post-selection inference in factorial designs [PDF]
arXiv, 2023 Ever since the seminal work of R. A. Fisher and F. Yates, factorial designs have been an important experimental tool to simultaneously estimate the effects of multiple treatment factors. In factorial designs, the number of treatment combinations grows exponentially with the number of treatment factors, which motivates the forward selection strategy ...

Two polynomial representations of experimental design
, 2007 In the context of algebraic statistics an experimental design is described by a set of polynomials called the design ideal. This, in turn, is generated by finite sets of polynomials.

On the Isomorphism of Fractional Factorial Designs [PDF]
Journal of Complexity, 2001 AbstractTwo fractional factorial designs are called isomorphic if one can be obtained from the other by relabeling the factors, reordering the runs, and switching the levels of factors. To identify the isomorphism of two s-factor n-run designs is known to be an NP hard problem, when n and s increase.

Optimal factorial designs for cDNA microarray experiments [PDF]
Annals of Applied Statistics 2007, Vol. 2, No. 1, 366-385, 2008 We consider cDNA microarray experiments when the cell populations have a factorial structure, and investigate the problem of their optimal designing under a baseline parametrization where the objects of interest differ from those under the more common orthogonal parametrization. First, analytical results are given for the $2\times 2$ factorial.

IsoCheck: An R Package to check Isomorphism for Two-level Factorial Designs with Randomization Restrictions [PDF]
arXiv, 2020 Factorial designs are often used in various industrial and sociological experiments to identify significant factors and factor combinations that may affect the process response. In the statistics literature, several studies have investigated the analysis, construction, and isomorphism of factorial and fractional factorial designs.
