At present, modern information technologies are actively used in the design of complex equipment at various industrial enterprises – automated systems for end-to-end CAD/CAM/CAE class design, which provide complex execution of design work with a significant reduction in their execution time while improving the quality of work. When this is achieved the main objective which is the update of the nomenclature of products, reducing costs, improving reliability, efficiency, etc. In view of this, the task of constructing and visualizing solid-state models is relevant today. From the analysis of the literature, it was concluded that today there are not enough methodological techniques for building models, and the existing developments do not contain optimal algorithms for creating 3D models of parts of varying complexity. Therefore, to implement the above problem, an algorithm for constructing a 3D model with a cutout was proposed.

The proposed article provides a generalized model of the hydraulic system of a drilling rig during the beginning of the introduction of the drilling tool into the ground. The oscillograms of the parameters of the motor in time are shown, obtained using a computational experiment in the Matlab program. Using this model, it is possible to estimate the transient processes of the hydraulic drive at the system design stage. The above formulas describe the parameters of the hydraulic system, determine the pressure at the pump outlet, the inlet to the throttled resistance and the input channel of the motor. Changing the input characteristics of the system allows you to monitor the behavior of the system in different situations and under different loads.

Abstract: in modern society in the process of formation of gender identity is of particular importance factor of information impact. The aim of the work is to study the psychological sources of information impact, which influence the formation of gender identity of students of different age categories (adolescents, high school students). The study confirmed the hypothesis that parents are the most reliable, accessible and influential sources of information that influence the formation of gender identity of schoolchildren. The study used: the method of ranking sources of information I. K. Kashirskaya, the method of "masculinity and femininity" (modification of T. A. Bessonova) and the method of "who am I?"(a modification of the T. V. Rumyantseva).

It is shown that the problem of simultaneous processing of dynamic information arrays of different degrees of structure and fuzziness is currently relevant. One of the prototypes of mathematical models containing such information structures is the problem of practical distribution of resources in the conditions of possible, difficult to formalize effects. In this problem there are two factor for the rational allocation of resources: network bandwidth to operating conditions and the preference of the routes of transmission resources on the network in terms of the alleged destructive effects. The high degree of uncertainty inherent in the process reduces the feasibility of resource-intensive distribution algorithms. At the same time, it is necessary to obtain a variety of alternative solutions with diversity in terms of resistance to possible impacts. Since, if all routes pass through one transit node, all of them will be equally exposed to the threats of impact inherent in this node, and when it fails, there will be no alternative routes, which will require re-search of routes for the transfer of resources. Fast heuristics, based, for example, on greedy approaches, can not provide the proper diversity, therefore, even with clear formulations of optimization problems, fall into local Optima. For this reason, it is advisable to Supplement the initial solution formation procedure with borrowed solutions from the previously considered problems. In order to improve the solutions obtained at the stage of formation of the starting population, and to ensure the diversity of the descendants of these solutions, describing the routes of resource transfer, an evolutionary algorithm for finding the set of the shortest time routes of resource transfer. The peculiarity of the process of solving the problem proposed algorithm is to maintain the diversity of the population of solutions to possible threats.

The article presents a detailed analysis of the structure of the model of management of the hematopoietic functional system of the body in various physiological situations, which activates the activity of a certain adaptive circuit that characterizes the functional state. The first state and adaptation to the contour of the functional hematopoietic system of the body included in the work are considered in detail. The structural equation of adaptation of the first contour is made. It is concluded that the equation of adaptation compiled for a hypothetical control model adaptation, in the actual state of Affairs raises a number of inconsistencies with the hypothetical implementation-related deviations from the ideal parameters of functioning: autonomic nervous system, internal environment, metabolic state, the processes of transmitting the control actions. All these deviations affect the observed realization of the set of blood form elements (RSBE).

The important function of the automatic process control system is the ability to forecast and control the quality of a product. The implementation of these functions can be done by using formal models that allow to do the quick reconfiguration of the technological process when the composition of the raw materials and the requirements of product characteristics are changed, etc. in relation to the prediction and management of quality indicators of road and construction bitumens, methods of getting formal models that relates bitumen quality indicators with technological parameters of their production both for classical regression equations and for formal neural networks.
