Based on single factor evaluation, landscape characteristics like slope and elevation were found extensively suitable.
The optimization of the extraction process was based on single factor experiments and Box Behnken design (BBD).
However, most existing studies investigated the factors individually and the related CR models were developed based on single factor only.
A response surface methodology (RSM) was used to optimize the parameters on UAE based on single factor experiment.
The optimized CIDR process was based on single factor analysis and nine well-planned orthogonal design experiments (OA9 matrix).
Based on single factor experiments, investigated liquid ratio, extraction temperature, extraction ph, settlement ph, and extraction time.
Based on single factor experiment, it studied the influence of chitosan, acetic acid, tetrabutyl titanate (TBT) and normal butyl alcohol mixture using a full factorial design.
Based on single factor experiments and the Plackett Burman design, the transesterification of castor oil and methanol was optimized using the response surface methodology.
Based on single factor studies, a three-variable, three-level Box-Behnken design (BBD) was used to monitor the effects of independent variables, including processing temperature and time, on the dependent variables.
