How to use analysis of variance correctly——an analysis of variance for the univariate quantitative data collected from the fractional factorial design

Sichuan jingshen weisheng, 2022
The purpose of this paper was to introduce the fractional factorial design and its quantitative data analysis of variance and the SAS implementation. The fractional factorial designs were very similar to the factorial designs and the orthogonal designs ...

SCREENING OF PIROXICAM SELF-NANOEMULSIFYING DRUG DELIVERY SYSTEM (SNEDDS) USING FRACTIONAL FACTORIAL DESIGN

Jurnal Kimia Riset, 2023
Piroxicam belongs to BCS class II and has low solubility. Self-nanoemulsifying drug delivery systems (SNEDDS) are considered a potential approach for increasing the solubility and release of piroxicam.

Providing laypeople with results from dynamic infectious disease modelling studies affects their allocation preference for scarce medical resources—a factorial experiment

BMC Public Health, 2022
Background Allocation of scarce medical resources can be based on different principles. It has not yet been investigated which allocation schemes are preferred by medical laypeople in a particular situation of medical scarcity like an emerging infectious

Factorial Design Analysis for Localization Algorithms

Applied Sciences, 2018
Localization is a fundamental problem in Wireless Sensor Networks, as it provides useful information regarding the detection of an event. There are different localization algorithms applied in single-hop or multi-hop networks; in both cases their ...

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.

Conseqüências da análise incorreta de experimentos blocados The consequences of incorrect analysis of blocked experiments

Química Nova, 2007
Errors are always present in experimental measurements so, it is important to identify them and understand how they affect the results of experiments. Statistics suggest that the execution of experiments should follow random order, but unfortunately the ...

Alternativa potencial para aproveitamento do glicerol gerado na produção de biodiesel: síntese enzimática de monolaurina por esterificação Potential alternative for using the glycerol generated in the biodiesel production: enzymatic synthesis of monolaurin by esterification

Química Nova, 2009
Esterification reactions of glycerol with lauric acid in solvent free system were carried out using lipases from several sources. All lipases were immobilized on polysiloxane-polyvinyl alcohol particles by covalent binding with high activity recovered ...

Factorial design-assisted spectroscopic determination of oxybutynin hydrochloride

Royal Society Open Science, 2021
In this study, we have developed two facile spectroscopic methods for quantifying oxybutynin (OBT) hydrochloride in its pure form and tablets using design of experiments (DOEs). The spectroscopic methods depended on the ion-pair complex formation between
