Fractional Factorial Design to Evaluate the Synthesis and Electrochemical Transfer Parameters of h-BN Coatings [PDF]

open access: goldNanomaterials, 2023
In this study, we present a fractional factorial design approach for exploring the effects and interactions of key synthesis and electrochemical transfer parameters on the roughness and wettability of hexagonal boron nitride (h-BN) coatings, due to their

Optimization of biomass pretreatments using fractional factorial experimental design [PDF]

open access: goldBiotechnology for Biofuels, 2018
Background Pretreatments are one of the main bottlenecks for the lignocellulose conversion process and the search for cheaper and effective pretreatment methodologies for each biomass is a complex but fundamental task.

Fractional Factorial Design and Desirability Function-Based Approach in Spice Paprika Processing Technology to Improve Extractable Colour Stability [PDF]

open access: goldPolish Journal of Food and Nutrition Sciences, 2022
The storage-stability of extractable colour in paprika powder is strongly influenced by the processing steps. The purpose of this research work was to decrease the degradation rate of extractable colour of paprika powders to 3-4 ASTA units/month and ...

The Use of a Fractional Factorial Design to Determine the Factors That Impact 1,3-Propanediol Production from Glycerol by Halanaerobium hydrogeniformans [PDF]

open access: yesLife, 2016
In recent years, biodiesel, a substitute for fossil fuels, has led to the excessive production of crude glycerol. The resulting crude glycerol can possess a high concentration of salts and an alkaline pH.

FRACTION: A computer program for fractional factorial design [PDF]

open access: bronzeBehavior Research Methods, Instruments, & Computers, 1988
Factorial designs are used efficiently and effectively to carry out experiments involving multiple independent variables needed to explain complex human behavior. These designs are not feasible, however, when a study requires a large and, in some cases, prohibitive number of measurements on the same subjects (within-subjects designs) or on groups of ...

Medium optimization for biomass production of three peat moss (Sphagnum L.) species using fractional factorial design and response surface methodology

open access: hybridbioRxiv, 2021
Peat moss (Sphagnum) biomass is a promising bioresource to substitute peat in growing media with a renewable material. For sustainable production on a large scale, the productivity of Sphagnum mosses has to be increased by optimizing culture conditions ...

Regularities in the Augmentation of Fractional Factorial Designs [PDF]

open access: yes, 2013
Two-level factorial experiments are widely used in experimental design because they are simple to construct and interpret while also being efficient. However, full factorial designs for many factors can quickly become inefficient, time consuming, or ...

Generation of Fractional Factorial Designs

open access: yes, 2009
The joint use of counting functions, Hilbert basis and Markov basis allows to define a procedure to generate all the fractions that satisfy a given set of constraints in terms of orthogonality.
