To assess the impact of various groups of sources of emissions in urban pollution, there is a method that can be called the main one - the assessment of the contribution to total gross emissions. But this method does not take into account the significant features of dispersion of pollutant emissions in the atmosphere, as well as the specifics of the mechanisms of formation of concentrations of pollutants at a specific point in the city and the calculation of complex indicators of the level of air pollution in urban areas. The authors proposed a procedure for calculating the atmospheric pollution index for source groups using the “summary calculations” tool. The calculations were carried out on the licensed software product "Ecologist-city". Based on the calculations, conclusions were drawn on the reliability of determining the influence of various groups of emission sources on air pollution in the city of Krasnoyarsk, based on the assessment of contributions to the total gross emission in the city.

The paper presents the results of studies on the effect of deposition regimes on the properties of electrochemical copper powders. The obtained ultradispersed powders of copper and application of different regimes of electrolysis. The paper presents data on the possibility of obtaining ultrafine copper powders (UDP) in pulsed mode with the addition of polyvinylpyrrolidone (PVP) as a particle growth stabilizer. The influence of the current amplitude and the cathode-anode time ratio is revealed. It is shown that the parameters determining the current wave determine the size of the deposited copper powder particles.

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. The method of getting such models has been worked out on abstract dependencies with further adaptation of the production of bitumen. According to the received formal models the automated process control system can solve both the direct problem of predicting quality indicators by substituting the input technological parameters for the model input, and the inverse problem using nonlinear programming methods to minimize the deviation functions of the quality parameters obtained from the model from the target values given operator technologist.

The problem of control of strength characteristics of agricultural machine parts by dynamic non-destructive methods of impact indentation of conical shape is considered. The quality of the most important parts is considered in terms of the set of mechanical characteristics that determine the strength, hardness, wear resistance and deformability. These characteristics should be known and be able to quickly and accurately control all parts both during production and during operation. The mechanical properties of metals are stochastic. For this purpose, a device for impact indentation was developed and a method based on the probabilistic laws of dispersion of mechanical characteristics was developed.

The article shows the possibility of describing complex objects with parallel functioning components in the form of structures built on the basis of neural networks. The neural network is represented by an operator matrix, that is, a formal description that gives a universal way to solve many non-standard control problems. Matrix apparatus is shown to significantly improve the efficiency of the method compared to previously known. It is concluded that the representation of the neural network by the operator matrix provides a universal way to solve the problems of transport and information flows management; neuron-like systems based on such representation of the neuron are able to catch complex nonlinear relationships, self-improvement, learning in the process of use. Their use provides ample opportunities for finding and implementing effective solutions to the problems of management and control of flows

At present, there is a tendency in Russian society, which is connected with the fact that modern people strive, first of all, for self-realization. Very often, in the process of forming career strategies, a person thinks about whether he is happy in his position after having worked in an organization for over a year. Sometimes, such thoughts force a person to change the type of activity or completely change the place of work. Thus, such a pattern of behavior as downshifting can be formed, when a person radically changes the quality of his life, life priorities and value orientations. The author of the article, in connection with such a change in the model of career behavior, considers the reasons that can influence the reorientation of value orientations from material to spiritual.

This paper presents two methods of computer simulation (quantum chemical analysis and molecular dynamics) of the interaction of additives with the iron surface. Quantum chemical interaction of silicate and phosphate additives with iron surface was carried out. The plate model was used for quantum chemical analysis, calculations were carried out in the DFT approximation. The method of molecular dynamics is based on the calculation of the evolution of the system of interacting particles of atoms and molecules by integrating the equations of their motion. It is shown that the oxidation of the surface leads to a decrease in the adhesion energy of both individual additives and their combinations, allowing to find the influencing factors on the behavior of tribosystems.
