Soursop is a typical fruit with high nutritonal value. Its perishability of soursop and the short shelf life after harvesting are main difficulties in enhancing its potential market for fresh consumption. The (Annona muricata) usually transformed into juice, pulp concentrate. In order to accelerate valuable characteristics, present investigation wascarried out optimiz different parameters proce...

Introduction. This article presents the development of mathematical models related to effect initial content dry matter, yeast, and yeast energizer on fermentation rate, alcohol content, matter in finished product – mead.
 Study objects methods. The were developed by using response surface methodology (RSM). contents tested concentration ranges 150–600 mg/L, 16.3–24.4%, 140–500 respectivel...

The identification of kinetic models is an important step for the monitoring, control and optimization of chemical processes. Kinetic models are often based on first principles that describe the evolution of concentrations by means of conservation and constitutive equations. Identification of reaction kinetics, namely, rate expressions and rate parameters, represents the main challenge in const...

The report deals with speech enhancement in a noisy environment. A new, direct shaping parametric formulation of generalised adaptive spectral subtraction algorithm for non-stationary interference is considered. The idea of the authors is not to select but to form desirable envelope of spectral estimator function in SNR*Gain-function area. Some principles of parameters choice are proposed, base...

Optical nanoantennas have been studied as a means to manipulate nanoscale fields, local field enhancements, radiative rates, and emissive directional control. However, a fundamental function of antennas, the transfer of power between a coupled load and far-field radiation, has seen limited development in optical antennas owing largely to the inherent challenges of extracting impedance parameter...
