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

Generation of 2n series fractional factorial plans robust against linear-trend
The Indian Journal of Agricultural Sciences, 2021 Trend-free design for single factor at two level factorial experiments (complete and fractional both) are available in literature but trend-free multi-factor design could not be traced in the literature.

Construction of Optimal Split-Plot Designs for Various Design Scenarios
Fractal and Fractional, 2022 When performing fractional factorial experiments in a completely random order is impractical, fractional factorial split-plot designs are suitable options as an alternative. It is well recognized that the more there are lower order effects of interest at
