Recently, the issues of improving the environmental situation in the urban environment have become more relevant than ever. "Green architecture" gets popularity not only in Russia but over the world as well. The necessity of this type of architecture causes the need to improve air quality and environmental factors of urban conditions. Most often, greening the roof of a building or greening the facades is used for ecologization, so-called the element of wall greening and also greening of vertical surfaces of buildings (phyto facade).

The article is devoted to improving the processing of radon flux density measurement data using mathematical processing. The article considers the influence of construction works on the radon flux density (RDP) indicators. for the purpose of the study, real measurements were taken at a mining and processing plant in the volgograd region. The article presents the construction of histograms and frequency polygons for measurements performed at different stages, as well as graphs of the empirical distribution function of a random variable. They clearly showed the impact of construction, the hypothesis of the influence of clay soils on the radon output from the soil was confirmed, namely, it was proved that the permeability of the near-surface layer of soil is one of the key factors determining the spatial PPR within homogeneous areas, that is, the permeability of near-surface deposits is one of the leading factors determining the distribution of PPR. analysis of the obtained results allows us to conclude that there is a correlation between the calculated data obtained and the data obtained at the measurement input, i.e. relationship of two or more random variables.

Currently, there is a rapid development of computing systems, including systems that include various types of devices. Such systems are called heterogeneous or heterogeneous. In addition to traditional processors, such a system may include graphics processing units, programmable gate arrays, and other devices. One of the most pronounced problems of such systems is the complexity of distributing the computational load between the nodes of the computing system. This paper describes the types of balancing and methods for distributing computational load in heterogeneous computing systems. An example of load balancing in a real heterogeneous computing system is described.

The article is devoted to the issue of improving devices for cleaning gas station emissions from hydrocarbon vapors to improve the environmental safety of inhabitant zones and territories of residential development. It is known that emissions of benzene vapors belonging to the second hazard class have a significant problem in terms of exceeding the maximum permissible concentrations at the borders of the sanitary protection zones of gas stations and nearby residential buildings. The largest part of the release of gasoline vapors entering the local aspiration systems is associated with the filling and emptying of fuel storage tanks at gas stations. To reduce emissions from gas station sources, it is proposed to use absorption-type devices in gasoline vapor recovery units. The article presents the results of experiments on a pilot - industrial plant set up with an apparatus for cleaning gas station emissions from benzene and other hydrocarbon vapors using a solution of a mixture of natural sodium-magnesium salts. As a liquid sorbent in such devices, it was proposed to use waste water from a gas station purification device in order to reduce the additional amount of waste generated during their operation. Based on the results of processing the experimental data, a graphical dependence and regression equations were obtained. The areas of aerohydrodynamic regimes at which the highest efficiency is achieved for the parameters of the apparatus of the studied modification are determined. This approach also makes it possible to reduce the negative technogenic impact of gas stations in terms of the generation of additional waste. The successful tests carried out have shown the reliable and efficient operation of the pilot plant set up with the proposed device.

The article reveals the results of the work carried out on modeling the dynamic model of the electric drive of the scanning mechanism of the Earth orientation device, which is based on a hybrid stepping motor. The simulation is based on NEMA 17HS3410 motor parameters. A brief description and features of hybrid stepper motors are provided. The simplest model of an electric drive is considered, in which there is a rigidly set moment of force, a moment of inertia of the rotor of an electric motor, and also the moments of dry friction and the moment of liquid friction are taken into account. It is shown how the change in the value of fluid friction affects the general behavior of the mathematical model of a hybrid electric motor. The behavior of a single-pole stepper drive is simulated. The relationship of the value of the moment of force acting on the rotor with the passport characteristics of the investigated electric motor is considered. The possibility of controlling the scanning mechanism based on P- and PI-controllers is estimated.

This article considers the option of using a simulation model in organizational conflict management as an intelligent analyzer of a conflict situation. It is proposed to build its own style of leadership, necessary and sufficient to successfully overcome the organizational conflict. Based on the model forecast, the manager constructs an appropriate solution within the framework of the variability of authoritarian, democratic and liberal styles of government with the help of the auxiliary variables available to him. This allows him not only to get out of the usual style of leadership, but also to choose the necessary and sufficient style in this case, to test style behavior strategies. The manager has the opportunity to use the management style that best suits the internal and external conditions of his activities. Today, managers must meet the emerging problems and the ability to solve them effectively with their stylistic variability.

The paper argues for the relevance of using volumetric modular units (VMU) in construction, especially in building temporary field camps. Despite a high installation technology intensity, the use of VMUs is said to demonstrate a low technology intensity in terms of transport operations. In order to ensure a high transport flexibility for temporary settlements, collapsible volumetric modular units are suggested as a potent solution.

In modern conditions, internal combustion engines (ice) are the most popular power plant for a number of transport vehicles: cars, tractors, locomotives, river and sea transport vessels. Strict requirements of modern Euro-standards to the degree of "smokiness" of exhaust gases of diesel internal combustion engines and their toxicity contribute to the emergence of a dead end situation. It is almost impossible, using obvious technical solutions, to comply with the requirements of Euro-5 and Euro-6 standards while maintaining the acceptable growth in economic costs, internal combustion engines (ice) emit a significant amount of exhaust gases into the atmosphere, which is an environmental threat. The article considers the method of SHS technology and its advantages.
