Comparison of Box-Behnken, Face Central Composite and Full Factorial Designs in Optimization of Hempseed Oil Extraction by n-Hexane: a Case Study
(PERIODICA POLYTECHNICA CHEMICAL ENGINEERING, 2018-01)
Statistical multivariate methods like Box-Behnken, face central composite and full factorial designs (BBD, FCCD and FFD, respectively) in combination with the response surface methodology (RSM) were compared when applied ...
Theoretical Study of Tool Holder Self-excited Oscillation in Turning Processes Using a Nonlinear Model
(International Journal of Acoustics and Vibration, 2018)
In this paper, by observing a system which is composed from a workpiece and a tool holder, a dynamic and a
mathematical nonlinear model is acquired. These models can be used as a theoretical foundation for research ...
Design of IIR Multiple-Notch Filters with Symmetric Magnitude Responses About Notch Frequencies
(Circuits, Systems, and Signal Processing, 2018-05)
A novel all-pass-based infinite impulse response (IIR) digital multiple-notch filter design method is presented in this paper. The proposed method ensures that, for an arbitrary pass-bands ripple value, specifications ...
OPTIMIZATION OF ULTRASONICALLY ASSISTED ADSORPTION OF Cu(II) ON CARBONIZED AND ACTIVATED WALNUT SHELLS
(Facta Universitatis Series Working and Living Environmental Protection, 2018-11)
The effects of ultrasound (US) on the adsorption process of Cu(II) on granulated activated carbon (GAC), produced by walnut shells, was studied in this paper. Equilibrium results of the adsorption process are tested by ...
Ultrasound-assisted extraction of sunflower oil from the cake after sunflower seed pressing
(Journal of Agricultural Sciences, 2018)
The influence of ultrasound application on the extraction (UE) of the cake after sunflower seed pressing was studied. Three different solvents were used for extraction in the Soxhlet apparatus: n-hexane, petroleum ether ...
