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 ...
