Statistical robust technique procedures for fractional factorial design with non constant variance
AIP Conference Proceedings, 2017Fractional factorial design (FFD) has been widely used in engineering, agricultural, biology and social sciences. Although FFD is considered a conventional design, there still occurs a basic problem such as nonconstant variance may affect parameter estimation.

Design and statistical analysis of confounded factorial experiments
2018Ten confounded factorial experiments were designed with the purpose of filling in the existing gaps among the available plans. The method of analyzing such experiments was presented and illustrated by the 5 x 2 x 2 experiment. For each design, the reasons why a particular plan was adopted were discussed; the instructions for computing the sums of ...

Development of nifedipine-loaded albumin microspheres using a statistical factorial design
International Journal of Pharmaceutics, 1996Nifedipine-loaded albumin microspheres were prepared by a chemical cross-linking method to develop a sustained-release form. The qualities of the nifedipine-loaded albumin microsphere products were affected by several variables. In this study, the effects on the percentage of nifedipine incorporated into albumin microspheres of four different variables

The optimization of spraying parameters to improve pesticide efficacy and reduce environmental impacts requires a large number of experimental treatments. Some experimental designs can be used to reduce the required number of treatment combinations. A comparison between a 33 factorial design and a central composite design (CCD) regarding the model ...

Evaluation of modeling accuracy of 20-node solid elements by statistical factorial design
Computers & Structures, 1994Abstract Many complex engineering structures consist of plates and shells. When applying finite element methods to a plate or shell, how can a design engineer choose an initial mesh and decide the integration order? The statistical design of experiments is employed to investigate the influence of three relevant modeling factors—aspect ratio, number ...

This work describes the tribological properties of mono AA6061-10 wt% B4C and hybrid AA6061-10 wt% B4C-7.5 wt% Gr composites which could be used as a potential substitute for aluminum alloys used in automotive engines. The tribological experiments are performed as per the experimental scheme designed using full factorial design.

This study examined the effects of total solids (TS), preheat treatment temperature, and first‐ and second‐stage homogenisation pressures on the stability of model infant formula emulsions, using factorial statistical design. Oil droplet size decreased with increasing first‐ and second‐stage homogenisation pressures.

Full factorial design of experiment was employed to evaluate the effect of variables on the settling performance of coal fine. Influence of the variable parameters was discussed using 2D surface plots. Settling rate and turbidity were more sensitive to the flocculant dosage followed by the pH and the feed density.
