THE METHOD OF CONSTANTLY OPERATING MODELS IDENTIFICATION FOR QUALITY CONTROL OF STUDENTS KNOWLEDGE
DescriptionBased 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

Description
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

Description
The article describes the details of modeling of catalytic systems for the production and conversion of energy in anaerobic digestion of organic manure. We have also presented a simulation mathematical model that establishes the relationship between structural and technological parameters of catalytic systems and the parameters characterizing the efficiency of the catalytic system in the production and conversion of thermal energy in the anaerobic treatment of organic manure

CONCEPT OF BREAK-EVEN POINT IN THE CONDITIONS OF A SMALL REPAIR COMPANY
DescriptionThe article has stated that, subject to the conditions of existence of break-even point, a negative value indicates the manufacturing arm of the loss-making activity of a small repair shop
-
Description
The article found that the distribution of the normal components of the along the length of the samples has no significant features associated with different magnetic characteristics, so the magnetization modes of an additive powder on the details of uncertain chemical composition must be installed on the tangential component of the magnetic field

EFFECT OF A PRODUCTION ARM IN THE CONDITIONS OF A SMALL REPAIR COMPANY
DescriptionThe article found that the targeted management of parameters affecting the production arm can influence the value of the break-even point and increase the potential for the formation of the gross profits of small repair shops
