Within the framework of solving the problem of increasing the effectiveness of the directional properties of adaptive systems with parametric sonar emitting antenna in the results of generalization of theoretical and experimental studies of the effect of hydro-irregularities on the characteristic parameter of the antenna. A comparison of the results of calculations of the antenna directivity characteristic parameter derived from the model Khokhlova-Zabolotskaya-Kuznetsova, with the results of experimental measurements of the directional properties of the parametric array. We obtain the normalized dependence of the width of the parametric characteristics of the antenna by lowering the difference frequency from the center frequency of the pump waves of 5 to 16 times. The influence of changes in the speed of sound in the direction of the parametric array. We obtain the normalized dependence of the width of the antenna characteristics of the parametric values of the sound velocity at the surface of the pump transducer. It was found that the greatest impact on the characteristic parameter of the antenna has a change in the speed of sound to a distance equal to the lengths of 1-2 zone diffraction of the pump waves.

Air pollution in residential areas near industrial plants is one of the most significant problems of modern ecology. The resulting dust is one of the important factors in assessing the adverse impact on the environment. Studies show that the greatest danger to the human body is particles up to 10 microns in size. When analyzing the dispersion of dust in the residential and industrial areas, it is possible to estimate the percentage of particles PM10 and PM2.5 from the total amount that is necessary to effectively control the effects of dust on human health. The article gives a comparative analysis of the results of studies of the dispersion composition and dust concentration in the air of the working zone and the urban environment.

This work is devoted to the modeling of the fuzzy assessment of the impact of human factors in emergency situations in industrial activity. Relevance of the research lies in the uncertainty, heterogeneity and uncertainties of the input data, on the basis of which it is necessary to assess the impact of human factors in emergency situations. The article describes the main stages of the fuzzy modeling: fuzzification of input data, the construction of inference rules and defuzzification of the output variable. The proposed base of fuzzy inference rules include input linguistic variables, fuzzy rule-production and output linguistic variable. The constructed model allows us to estimate the degree of influence of the human factor in the conditions of uncertainty and subjectivity.
