One of the most pressing problems at the present stage of industrial development is the presence of cases of oil spills caused because of technological accidents and accidents. With advanced achievements in the field of digital technologies, it seems possible to au-tomate the process of identifying oil spills. The main purpose of the current article is to analyze the possibility of using unmanned aerial vehicles to perform automatic identification of oil spills. The author investigates this issue, and presents an option to increase the use of these systems based on the development of a special image-processing algorithm based on exponential accumulation and the variance method. The results of the work confirm the hypothesis of the effective use of unmanned aerial vehicles for automatic identification of oil spills.

The most important task of the admissions committee of any university is to advise applicants on admission to the specialties available at the university. In this article, an automated information system has been developed, which, based on the applicant's questionnaire, allows you to form recommendations when choosing a training specialty, taking into account the applicant's personal preferences. Artificial neural networks are proposed to be used as a method of choice, and the multilayer perceptron (MLP) was the model of the neural network.

Experimental studies of the effect of the intensity of mixing of mineral coagulants with water on the efficiency of water treatment in different periods of the year have been carried out. The studies were conducted in June-August - low-turbidity water with relatively low color and high temperature; November-December - low-turbidity and low-color water with low temperature; flood in April-May - increased turbidity and color of water with low temperature and alkalinity. The results obtained allow us to evaluate the effectiveness of the use of concentrated coagulation, high-gradient mixing in water purification with mineral coagulants. The possibility of separate and joint use of mineral coagulants in different periods of the year was assessed.

The article describes four developed designs of samples of joints of solid wood elements on aluminum linings. They made it possible to simulate the operation of real connections of the main and secondary beams, as well as crossbars and columns. Tests of connection samples were carried out, one of the four developed variants of sample designs was selected that most fully reflects the actual work of real joints of wooden elements. The strength and deformation characteristics of the joint, the upper boundary of the elastic work area (VGOUR) of the joint are determined. Based on the conducted research, the peculiarities of the work of the studied compounds were determined, a sample of the connection of a wooden element with a metal overlay was developed, which allowed the development of measures aimed at increasing the bearing capacity and reducing the deformability of the studied compounds without significant material costs associated with the purchase of expensive SHERPA linings.

Many sources of environmental pollution affect human health. The concentration of harmful substances constantly changes during the day when the weather conditions change in different parts of the territory. Residents can repeatedly enter and leave areas of increased pollution without noticing it with their senses when moving around the city. The authors analyzed the existing solutions for monitoring the quality of atmospheric air, as well as key sources of pollution and their distribution in the air. The interrelation of distribution of pollutants with weather conditions is noted. Preparation of data on the presence of harmful substances on the example of the city of Volgograd has been carried out. A method for organizing monitoring of harmful substances in the atmosphere using a software and hardware complex is proposed. The developed method was applied to create a specialized web application. The implemented solution allows to monitor the state of the environment using sensors and build routes around areas with a high concentration of harmful substances.
