Abstract:

The developed dynamic method of integral heat fl ux determination is based on the single-capacity dynamic model of the thermal state of the temperature measuring transducer (TMT), experiencing thermal infl uence of the constant infrared radiation fl ux and natural convective heat exchange of the TMT surface with the surrounding air. The model can help determine the permeability of moist agricultural raw materials. The eff ectiveness of the integral heat fl ux method was tested by studying the infrared radiation permeability of a layer of purifi ed drinking water with salinity not exceeding 1 g

Abstract:

When substantiating the method of fast selection of the bandwidth of kernel probability density estimates, a constant was found that is a functional of the second density derivative. In this paper, the obtained result is generalized to derivatives of symmetric probability densities of different orders. The functional dependences of the constants under study on the coeffi cient of antikurtosis of a random variable are established. The regularities peculiar to them are investigated. Based on the results obtained, a method for estimating functionals from derived probability densities has been dev

Purpose. The purpose of the paper is to find the features of atmospheric air pollution depending on the level of the urbogenic load of the Ukraine regions by the indicator method. The methodology of the work is based on the used complex indicators - the indicator of ecological and index of ecological-demographic urbanization. Results. Compara- tive analysis of dynamic changes in unit indicators per person of emissions from mobile and stationary sources for the period 1995 – 2020 has been executed. It is shown that the urbanization process in the whole country was reflected in a 1.8-fold reduct

Экспериментальным материалом послужили данные перечислительной таксации на 24 пробных площадях. В ходе проведенных исследований установлено, что придорожные защитные лесные полосы разных пород заметно отличаются по степени дифференциации деревьев по диаметру и высоте. В порядке умень- шения коэффициента вариации размеров стволов их можно расположить в следующий ряд: вязовые, клё- новые, берёзовые, сосновые и тополевые. Дифференциация деревьев ка

The dependences of the spacer force and feedback gain on the current value of the friction coeffi cient are found, for which an adaptive friction coupling with a variable gain value has a theoretically ideal load characteristic. It is proved that the real way to increase the coeffi cient of multiplicity of increasing the rated load capacity of the coupling is to increase the number of friction pairs of the friction group.
