The aim of this study was to assess selected properties coatings incorporating nanocellulose, with the potential being applied as a surface modification for cellulosic and lignocellulosic materials, particularly applications within biodegradable packaging. Cellulose nanocrystal (CNC) cellulose nanofibril (CNF) were produced on both sides pure samples in form filter paper Mayer bar. Selected org...

In this paper, a novel technique for the design of two-channel Quadrature Mirror Filter (QMF) banks with linear phase in frequency domain is presented. To satisfy the exact reconstruction condition of the filter bank, low-pass prototype filter response in pass-band, transition band and stop band is optimized using unconstrained indirect update optimization method. The objective function is form...
