The issues of modeling the interaction of humans and robots in a common operating environment are considered in order to select the optimal parameters of such a system. The context of the application of multi-agent robotic systems (MRTS) is the monitoring of a fire hazardous area. The homogeneous MRTS includes unmanned aerial vehicles (UAVs) that cyclically perform operations of flying around their area of ​​the territory (with identification of fires) in an autonomous mode, returning to the charging base, waiting for charging, charging, returning to their area of ​​responsibility, flying around their area, etc. etc. An operator works in the charging area, to which the UAVs should not approach less than a certain distance. The system is presented as a multi-channel queuing system (in the charging area). A simulation model is constructed that allows, according to the data of many runs, to construct polynomial regression dependences of the quality indicators of the MRTS operation on its parameters, by which to solve the multicriteria problem of choosing the optimal parameters of the MRTS charging terminal.

The article deals with the forecasting of direct material damage to urban areas depending on the number of fires based on official data of the Ministry of Civil Defense, Emergencies and Elimination of Consequences of Natural Disasters, presented in state reports on the state of protection of the population and territories of the Russian Federation from natural and man-made emergencies for five years, based on the model of correlation analysis, which allows us to determine the degree of mutual influence of the parameters under consideration and the linear regression responsible for determining trends for subsequent years. The analysis of the reasons associated with the lack of the possibility of assessing the damage resulting from the fire of the structures of the building or its premises and its subsequent extinguishing in order to increase the economic efficiency of the cost examination during the restoration of real estate is an auxiliary basis for the construction of a correlation-regressive forecasting model.

This article examines the implications of the application of quantum computing in the field of image processing. A basic conversion associated with gray level processing, such as an image negative, is considered. The article shows how this operation can be expressed using quantum formalism. Whether quantum image processing (in some aspects or some specific applications) has an advantage over classical image processing in realistic scenarios remains to be seen. This depends on solving a number of problems, some of which are unique to quantum image processing, such as feature extraction of a quantum image. Some of them are common to quantum algorithms, such as noise processing. Identifying one of them will significantly speed up the study of this field.

A study of the quality of drinking water (spring and centralized water supply) was conducted. Determination of water hardness and alkalinity was carried out by titrimetric analysis methods in a chemical laboratory. The dependence of these parameters in the autumn and spring period is established. The limits of changes in water hardness values are 3.4-9.9 mmol / l in autumn, 3.2-9.8 mmol / l in spring. Most of the studied natural waters are of medium hardness and hard water, therefore, there is a need for water softening. The limits of change in the alkalinity of water are 0.6 - 5.1 mmol / l in autumn, 0.8-5.3 mmol / l in spring. The alkalinity values of all samples are within the limits of the MPC norms. A comparative analysis of the results of the study is carried out, which establishes the dependence of the hardness and alkalinity of water in different seasons. The values of water hardness decrease during the flood, while the values of alkalinity increase during this period. It is recommended to conduct further research in order to determine the feasibility of using water softening methods for objects where water has high hardness values, and to choose the optimal softening methods.

In modern times due to the growth of mass production of electronic devices, it becomes necessary to quickly and accurately verify their characteristics. At the same time, device testing, as a rule, includes a set of different types of checks performed at different stages of the production process. In particular, the analog signature analysis method is used for these purposes. It allows you to quickly detect faults at the component level, which makes it useful in various stages of production, such as incoming inspection, testing printed circuit boards or repairing faulty devices. This article discusses the basic principles of the method, as well as the features of its application.

This work is devoted to the problem of conducting a construction and technical judicial examination of a rolled roof after repair. The relevance of the use of roll roofing and its defects are considered. An example with a poor-quality roof repair is reviewed. Besides faults of the management of the homeowners' association were noted. These faults led to the emergence of ambiguity during the examination. They do not allow to interpret the situation in favor of the residents of the house fully, despite the obvious violations of the requirements of regulatory documents and the identification of significant defects. Considered a situation in which a dispute about the type of repair and related judical issues arises. Conclusions based on the results of the study were made.

The aim of the work was to analyze the advantages and disadvantages of a typical 2-room apartment and find the optimal solution for redevelopment. As an example, we selected a typical planning solution from the developer of a two-room apartment in a multi-storey residential building. The article considers a variant of apartment remodeling in order to improve the housing characteristics of the premises. It is concluded that the typical rational solution for reconstruction is the reorganization of auxiliary premises in favor of residential premises, changing their configurations. The logic of applying the principles of free planning is reduced to creating conditions for comfortable spatial interaction of functional zones.
