The search and determination of the amount of biological resources is an urgent task, both from the point of view of food security of the Russian Federation and from the point of view of ecology. Most of the biological resources in the ocean are concentrated in shallow water zones (at depths from 1 to 200 m). The paper presents the results of the development of a parametric traverse survey sonar for searching for biological resources in shallow water. The calculation of the energy range of the parametric traverse sonar is given. The full-scale sea tests of the developed model of the traverse survey sonar in the Taganrog Bay of the Sea of Azov (shallow water conditions) are given. The average depth of the landfill was 2.2 meters. The oscillogram of the echogram recording line when determining the maximum detection range of a target in shallow water (reflected signal from a target at a distance of 1100 m) and an echogram from a target that moves away from the traverse sonar antenna at a distance of up to 800 m are given. Conclusions are drawn about the prospects of using parametric traverse-view sonars to search for fish aggregations in shallow water.

The influence of the content of the zeolite component in the composition of cobalt catalysts for the synthesis of hydrocarbons on their physico-chemical properties is investigated. The catalysts were obtained by impregnation of a zeolite-containing carrier with subsequent heat treatment. The obtained samples with a concentration of ZVM zeolite of 30-70% were characterized by the methods of BET, TPR, TPD H2. The results of the analysis show that an increase in the concentration of the zeolite component of the catalyst contributes to an increase in the specific surface area, dispersion and a decrease in the recovery temperature of the deposited cobalt.

The article presents the results of a study of the photoelectric response of cobalt-containing ferroelectric ceramics (1-x)Ва0.95Pb0.05TiO3+xCo2O3, synthesized at the Institute of Solid State Physics of the University of Latvia using conventional ceramic technology. Ceramics was exposed to optical radiation at room temperature. Before applying light radiation to the cellular electrode of the ceramic sample located in the measuring cell, zero current was recorded for 0.5 minutes in the absence of illumination using a high sensitivity digital electrometer. Then, the photoresponse was recorded during the time until its value remained constant (since the anomalous photovoltaic effect manifests itself in the form of constant currents flowing along the polar directions) and only then the light flux was turned off. A significant effect of the concentration of cobalt oxide on the value of the photovoltaic current is shown, which manifests itself in a decrease in the value of the stationary current with an increase in the content of the impurity of cobalt oxide. It is assumed that a possible reason for the decrease in the stationary current is deep charge traps, which is due to an increase in the cobalt concentration in the ceramic. The influence of the incident radiation wavelength, as well as the aging factor on the photoelectric response for ceramics with the highest concentration of cobalt oxide, is established.

In a number of branches of agricultural production, including agriculture, land reclamation, etc., there are problems, the solution of which requires the use of artificial intelligence. In particular, the assessment of the reclamation state of agricultural fields in large areas is a very time-consuming task, even with the use of unmanned aerial vehicles. To automate these intelligent approaches, it is effective to use artificial neural networks (INS) implemented in the form of computer programs. The use of software as a service (SaaS) is a modern approach to computer support of various intelligent production processes, including agricultural. Agriculture is a promising industry for the introduction of such technologies. The aim of the study is to develop a methodology and create a cloud-based SaaS system for identifying defective areas of agricultural fields based on INS. The development of neural network technologies and cloud services makes it possible to process a large amount of information in the cloud and provide user access to computing power. The article describes the methodology of building a service architecture for recognizing problem areas of cultivated agricultural fields, data preparation, network training, development of client and server parts. Such implementation is possible with the use of such technologies and tools as CUDA, CNN, PyTorch. As a result, the strengths and weaknesses of their use for solving the problem of image recognition on the example of problem areas of agricultural fields were identified. It has been established that classification-type INS are capable of solving problems of recognizing the reclamation state of fields, and modern information technologies make it possible to transfer calculations to the cloud, while the cloud service can be monetized as a SaaS model.

Artificial intelligence methods can be used to solve the problems of agricultural production. Assessing the condition of crops in large areas, even with the use of unmanned aerial vehicles, is a time-consuming task. The peculiarities of the task of such an assessment are the multifactorial nature of the analyzed structures, which require the use of a systematic approach at all stages of the study from the formation of a database of color images to the intelligent solution of problems of their analysis. The results of the analysis of the U-net architecture of the INS and its limitations for the problem of image segmentation are presented. The purpose of the study is to substantiate the architecture of the segmentation artificial neural network (INS) to identify problem areas of agricultural fields. The hypothesis of the segmentation network advantage was tested on the DeepLabV3 ResNet50 architecture. Numerical experiments have established that the increase in the accuracy of segmentation of images of agricultural fields is constrained by the limited resolution and accuracy of manual markup dataset. The built architectures can be used as an algorithmic core for creating SaaS systems, while the performance of the used configuration of the INS can be crucial.

The paper presents an evaluation of the efficiency of the use of road trains for transporting fuel chips during operation in real natural and industrial conditions through the variability of the coefficient of adhesion weight (kst). The authors of the paper note that the transport and transposing aspect of the technological process is especially important in the formation of efficient technological chains for the production of biofuels and, in particular, wood chips for energy purposes. The analysis showed that it is rational to use wood chip trucks based on all-wheel drive vehicles (6x6) to ensure movement in all modes when operating in complicated and challenging conditions on road surfacing in an unsatisfactory condition. Vehicles for transporting wood chips for energy purposes, manufactured in Russia and Belarus, are at the level of foreign analogues in terms of the main technical and economic indicators, and in some cases surpass them.

The application of the results of hardness measurements and its modeling in CAD as a 3D model is considered. Different welding modes were applied and electrodes CT-15, OZL-8 and CL-11 were used as consumables. The test material is a hot-rolled pipe with a diameter of 159 mm made of corrosion-resistant steel 12X18N10T with a thickness of 6 mm. The electrodes were fused to half its length and removed from the electrode holder, after cooling the remainder of the electrode, it was reused. For scanning measurement of microhardness of samples with a load of 100 g, the scanning step was applied 0.5 mm. The use of modern software was able to more accurately simulate the test results on a 3D model. The samples are welded with CT-15 electrodes at a maximum current of 100 A. the hardness is over 450-550 HV, regardless of what the passage was. Similarly, when welding with OZL-8 brand electrodes, but only at low currents, the hardness exceeds 450 HV. In both electrodes, the hardness is increased. When using OZL-8 electrodes, samples welded at high currents have less hardness than at low currents. When welding with these electrodes, it is possible to use them in certain passages, for example, when surfacing the root layer of the seam. In the case of full penetration in high-current modes with CT-15 electrodes, the result differs little as in low modes.

The essence of the proposed is the arrangement of the frame from the channel around the coating beam. At the same time, the frame elements can be subjected to controlled effects, in the form of overvoltage in them, which is realized by specially installed traction brackets. The study of the proposed structural and technological solution, implemented by a channel frame, was carried out using digital technologies based on numerical modeling. In the proposed calculation model, the beam reinforcement area was changed due to the introduction of a reinforcement frame. In the Etabs software package, using the finite element method, transverse forces and moments were calculated in the newly formed system - a beam plus a channel frame. The paper considers the issue of the influence of the frame on the transverse force in the beam. Using the technology of processing large arrays of numbers, a mathematical model of the process was obtained when the beam was reinforced with a channel frame. A consistent analysis of the mathematical model was carried out, which allowed to state the correctness of the decision and assign the design dimensions of the device and its technological parameters.

As part of the optimization of the design solution, studies of a cylindrical rod roof with increased rigidity of the support ribs and taking into account the reinforcement of the system with puffs were carried out. The required distance between the tension elements along the length of the structure is determined and the dimensions and shape of the section of the lower ribs are proposed. An optimality criterion with control parameters has been developed and three standard sizes of rods for the greatest efforts have been taken into account. Internal force factors and node movements with and without reinforcement are obtained. A positive redistribution of efforts on the surface and a decrease in the deformability of the roof were revealed. The dependence of the main geometric parameters on the mass is established.
