The article describes the developed radiometer for Express measurement of alpha radiation of radioactive elements based on a large-diameter silicon detector. The main element of the PPD detector is made using computer mathematical modeling of all stages of the technological process of manufacturing detectors, taking into account at each stage the degree of influence of the properties of the initial silicon on the electrophysical and radiometric characteristics of the detector. Detectors are manufactured for certain types of devices. The developed radiometer is designed to measure alpha radiation of natural isotopes (238U, 234U, 232Th, 226Ra, 222Rn, 218Po, 214Bi, etc.) in various environments. It also shows the principle of operation of the device, provides a block diagram of the measuring complex, describes the electronic components of the radiometer, as well as the block diagram. Signal transformations (spectrum transfer, filtering, accumulation) are implemented programmatically on the basis of a digital processing module. The device can detect the presence of specific elements in various environments, as well as protect people from the harmful effects of adverse radiation and can be used both in the field and stationary.

This article discusses the possibility of mathematical modeling andoptimization of parameters of the process of buckwheat. As a result of the research,a regression equation was obtained, which allows to predict the optimal extrusionparameters of buckwheat and reduce the number of experiments. Extrusionprocessing is one of the most attractive methods of processing grain crops to obtainsemi-finished products. The efficiency and effectiveness of the use of this equationis proved in laboratory conditions. The influence of all factors was studied duringthe extrusion of buckwheat grain, pressure, temperature, processing time andhumidity of the feedstock on the yield of blasted cereal, the content of watersoluble substances, the swelling and density of the extruded raw material. Amathematical model of the process of extrusion of buckwheat grain made itpossible to find rational process parameters allowing to obtain extrudates with highconsumer properties.

The high efficiency of the technological process of surface soil compaction using vibration and vibro-impact treatment hasbeen determined. High degree intensification of the soil compaction process is achieved by using original inertial vibratoryrammers with a hydro-pulse drive. A new mathematical model has been developed for the surface soil compaction processesstudy by the inertial vibratory rammers. Using numerical modeling, work dependencies are obtained to determine the mainoperating characteristics for the technological process of surface soil compaction by inertial vibratory rammers based on ahydro-impulse drive.

To determine the optimal parameters of machines for isolating the seed mass of vegetable and melon crops, a modeling method is presented, which is based on the nonlinear canonical decomposition of a random vector. A block diagram of the procedure for calculating the parameters of the canonical expansion is presented. The method of mathematical modeling was tested in the study of the technological process of separating melon seeds on an experimental installation. Mathematical models of the third order for purity and loss of seeds are presented, describing the technological process of separation for melon seeds.
