In this article we show the results of a pilot study of frequency regulation of the synchronous motor with a double anchor winding. The rational law regulating the frequency converter and the possible ranges of the frequency regulation and the engine load are defined
The influence of technology on the fortification composition of biologically active substances of wine and the Cahors beverage type has been examined. We have also established and explained the dependence of the content of phenolic compounds, including carboxylic acids from the ways of alcoholization.
A way of fortification, contributing to the enrichment of wines and beverages such as Cahors with biologically active substances has been shown
Based on the theory of self-organization, we have developed an original method for identification of target functions students’ knowledge quality (SKQ) in the face of influencing factors uncertainty. The proposed system of external criteria for the models selection and control parameters allows to use the model for the effective management of the SKQ
The negative economic consequences of using sun-flower seeds infested by molds Phomopsis helianthi Munt. Cvet. et al. as inoculums are described in the article. The necessity of finding the ways of these molds inactivation alternative to the way of chemical disinfection, and the advantages of usage of electro-physical ways of seeds’ treatment for this purpose and in particular electromagnetic field (EMF) of microwave frequency (MWF) are explained. The construction of the laboratory experimental setup is shown, on the bases of which the process of Flagman variety of sunflower seeds disinfection EMF MWF is researched. The testing technique is described too. The observable sowing sunflower with the starting infection rate by phomopsis at 22% is treated for different durations in the EMF MWF, being in either static or continuously mowing layers. As result of these experiments the particular rates of treatment providing the total disinfection of sunflower seeds from molds Phomopsis helianthi Munt. Cvet. et al. are revealed and the discovered contradictions in the experiments’ results are explained
