The present cultivators of the soil have a negligible width and depth of loosening is mainly up to 0.6 m. When the number of racks is significantly reduced completeness of loosening, increases the mass of the gun and increase traction resistance. In addition, the possibility of loosening soil to a greater depth is limited. There are rippers with surround deformers. They are inclined relative to each other vertical knife rack, rigidly connected to each other in the lower part with shingles made V-shaped with the apex directed upwards. In this architecture, the system deformers there is a need for analysis to determine the tensile strength in a first approximation: as much as possible to lengthen the elements of the blade without loss of strength and significant changes in their geometric characteristics of the flat cross-section. Reviewed the formulation of the calculation of the strength of the isotropic sloping steel plates of finite dimensions, a polygonal profile with rigidly clamped opposite edges of constant cross section, equal stiffness, as an element of deformers of the chisel type surround. Shows the justification of the selected geometric characteristics of the broken plate. Presents a preliminary finite element modeling using the software - computing complex Structure CAD (SCAD), considering static and dynamic loads. In the formulation of the numerical calculation primarily pursued the goal of establishing the adequacy of a solid model of the stress – strain state of a polygonal sloping steel plates of constant cross section with rigid pinched at the edges. It is established that the threat is a reduction in the actual thickness of the plate more than 1/3 of the project, which leads to failure of the individual piece of details. With little loss of thickness plots of displacements is characteristic reflects a valid value.

The action of the microwave field is used for drying, pretreatment and disinfection of grain. In all these processes, it is very important to control the change in the parameters of the grain layer. The use of sensors for direct measurement of temperature and humidity of grain and air is difficult. The microwave field leads to errors in the measurements, and therefore the possibility of an indirect control of these quantities is considered. For the indirect measurement of these quantities, a computer model has been developed. To develop a computer model, a system of equations was used that describes the exchange of heat and moisture in the grain layer under the action of the microwave field and convection. Some equations in the mathematical model are partial differential equations. To develop a computer model, these equations were presented in an operator form. The article shows how this procedure was used to transform the equation showing the relationship between the grain temperature and the microwave field, air temperature and moisture content of the grain. This approach allowed the use of computer software for analysis and syn-thesis of control systems. In this case the Simulink software package was used. Simulink - a model for the exchange of heat and moisture in a thick layer of grain, when exposed to microwave and air, was created using elementary dynamic elements of automation. When developing a computer model, a step-by-step method is implemented. The essence of the method is that the grain layer is divided into elementary layers. The output parameters of one grain layer become input parameters for the next layer. A complete model for the exchange of heat and moisture in a layer of grain consists of models of elementary layers. The results of modeling the change in the temperature of grain heating confirmed the adequacy of the model. The use of this model in the control systems of drying and processing of grain will increase the accuracy of control and regulation.

In general, games like duels, in which each of two players has the goal to eliminate the enemy, are quite a popular problem from game theory. The problem becomes much more complicated when you add players. The term ""truel"" we understand the rivalry three players. They are assigned some values of accuracy the probabilities of eliminating the opponent in one shot. At each stage of the game is chosen by the active player (the selection rule active player either randomly or by prior agreement between the players about their participation). The active player chooses an opponent to eliminate or passes the course. Developed mathematical models for different formulations of the conditions of the game (random or fixed choice of the active player). For each model are analyzed based on the probability of winning in the ""truly"" of accuracy, based on randomly generated program values. Comparing analytical solution and simulation, we see that they have the same answers. For large dimensions similar games analytical method requires complex calculations, so an acceptable alternative is the simulation method.

The article discusses research methodology of intrapersonal conflict by using the affective component of appropriate social attitudes. We analyze three kinds of internal contradictions. Which are classified by K. Levin as the conflict of ""Desire-Commitment"", ""Avoidance-Avoidance"" and ""Commitment-Avoidance"". They are all connected with a choice of appropriate object or action (equal or different valences) of the two equally probable. The affective component of perception of such internal contradictions is determined by the technology of semantic differential on the basis of the survey conducted at the end of 2016 among students DSTU. For the interpretation of the results used the previously developed technique. The distribution functions of the emotional perception of those conflicts are described in article. Which were calculated as in the linear approximation and a nonlinear lookup psychosemantic model. It is obtained that the average affective perception of the studied conflicts neutral or close to that. But the researched audience is very heterogeneous in its emotional attitude to such conflicts. The distribution function is strongly smeared almost all over the range of levels of perception. While approximately half of the respondents are characterized by positive attitude to internal contradictions. This suggests that positive role of conflicts associated with the resolution of problems of an appropriate level subconsciously affects on estimates. A few unexpected results were obtained by a comparison of the perception of conflicts ""the Desire-the Desire"" and ""Avoidance-Avoidance"". Distribution function for the problem of the choice of two positive options is being shifted to the left, in the negative direction, compared with the function for a choice of two unattractive possibilities. The work has shown the promising use of such figure as the affective perception for researching of intrapersonal conflict. The obtained results possess as General methodical so purely situational, specific significances.

The paper presents a numerical study of the effect of external electromagnetic fields of various configurations on the computer model of a neuron; Briefly describes the created software product, allowing to conduct numerical simulation of nerve cells, the mechanism of conduction of the nerve impulse. In an alternating field, the ion flux behaves as follows: at frequencies below 1 kHz, 3 maxima of the function of the average ion velocity are observed: these are 82 Hz, 340 Hz and 801 Hz. Under the influence of fields of higher frequencies from 1 kHz to 900 kHz, strong changes in velocities and currents do not occur. It is possible that in this frequency range the field does not have time to change the velocity modulus, but at a frequency of 970 kHz there is a sharp increase in the average ion velocity, which is most likely related to the effect of the myelin sheath, since no maximum is observed from the myelin sheath.
