A new approach to the calculation of unmanned aerial vehicles in an environment with predetermined external disturbances is demonstrated. A geoscan is chosen as a control object because it is the most maneuverable among other unmanned aerial vehicles and is designed to operate in a limited space environment, designed to perform tasks in mountainous and urban environments. External disturbances, such as wind gusts, inevitably act on the geoscan during flight, so the article deals with the issues of analyzing the mathematical model of the geoscan taking into account external disturbing influences. Mathematically modeled dynamic actions to piecewise constant external disturbances, the worst disturbances occurring during the flight of the geoscan.

In this study, the effectiveness of using a mechatronic system in the incubation of silkworm eggs was studied. The incubator consists of an SCD41 sensor, an ESP32 microcontroller, a TES1-12706 air cooler, an electric heater and a ventilation systembo'lib, harorat, namlik va CO2, which provides automatic control of temperature, humidity and CO2 quantity2. The study showed that when using the new system, the level of egg viability increased by 4.1%, and the yield of cocoons-by 5.8%. However, the overall length of the silk fiber and the continuous length have also been improved. This innovative system can be of great importance for improving product quality and ensuring economic efficiency in the silk industry.

Urban area inspections often present unique challenges for unmanned aerial vehicles (UAVs), requiring adaptable and responsive systems to navigate complex, dynamic environments. This study explores the integration of Artificial Neural Networks (ANN) to enhance the capabilities of small UAVs specifically for urban inspections. By leveraging ANN models, UAVs can improve obstacle avoidance, optimize flight paths, and enhance image processing for real-time data analysis, all of which are critical in densely populated and infrastructure-heavy areas. We conducted a case study to evaluate the performance of ANN-enabled UAVs in typical urban scenarios, assessing improvements in operational efficiency, safety, and accuracy. The findings suggest that incorporating ANN significantly enhances UAV performance, offering a robust solution for detailed urban inspections, monitoring, and data acquisition. This research contributes to the development of autonomous UAV systems capable of addressing the demands of urban environments with high reliability and minimal human intervention.

In the general complex of technological operations, sowing wheat seeds between cotton rows is one of the most difficult tasks. The uniformity of seedlings, facilitation of subsequent operations, yield and quality of the final product depend on the quality of seed sowing. The solution to the problem lies in the development and creation of a unit and the installation of small-sized coulters on runners. This article analyzes and defines the parameters of a hinged-skid coulter for sowing wheat seeds between cotton rows.

The lower reaches of the Amu Darya River face unique challenges related to hydraulic flows and channel processes, significantly impacting the region's water management, agriculture, and ecology. This article explores the foundations of developing methods for analyzing and managing hydraulic river flows and channel elements in this critical region. It traces the evolution of hydraulic engineering techniques, highlights the specific factors affecting flow dynamics and channel stability, and discusses contemporary approaches to modeling and mitigating issues such as erosion and sedimentation. Understanding these processes is crucial for sustainable river management, ensuring water security, and maintaining ecological balance in the lower Amu Darya.

Physical education of elementary school students has its own characteristics due to their anatomical, physiological and psychological characteristics, as well as adaptation to new conditions. With the beginning of studies, the amount of mental work of children increases significantly, and their physical activity and ability to be outdoors is significantly limited. In this regard, proper physical education at primary school age is not only a necessary condition for the comprehensive development of the student’s personality, but also an effective factor in increasing his mental activity. Therefore, in terms of relevance, this topic should occupy a leading place in pedagogy.

For the first time in scientific research, effective compositions of copolymers based on environmentally friendly aminopolysaccharide chitosan and acrylic acid and styrene were developed and scientifically based. The scientific significance of the research results was explained by the fact that a copolymer was obtained from acrylic and styrene.

In this paper, the strain gauge response of manganese-doped silicon is studied as a function of manganese concentration, ranging from 1×10¹² cm⁻³ to 1×10¹⁵ cm⁻³, at different temperatures. Mathematical modeling is performed, including calculations and plotting of graphs illustrating how the strain gauge response depends on manganese concentration and temperature.

The process of producing NP-fertilizers by nitric-sulfuric acid decomposition of phosphate rock (17.20% P2O5) under thickening slurry conditions has been studied. It was shown that the higher the recycle ratio, the lower the moisture content of the final product. Increasing the HNO3 dosage above 30% and H2SO4 above 70% is undesirable, as the product's moisture content exceeds 6.03% and it has increased acidity. To avoid issues during ammoniation, an optimal rate of nitric and sulfuric acid was proposed—73.5-91%, which produced products containing 9.34-10.61% -P2O5total; 3.04-4.54% N; P2O5 digestive:P2O5 total = 73.4-82.3%; pH = 3.3-3.6, and granule strength of 2.1-2.3 MPa. The process of producing NPK-fertilizers was also studied by adding nitrogen components such as K2SO4, KCl, and K2CO3 to the products of complete nitric acid decomposition of washed and dried concentrate (24.10% P2O5) and fine fractions (18.55% P2O5). The process includes decarbonization and decomposition of the phosphate raw material (simultaneously in one apparatus), neutralization to a pH not lower than 3.5, evaporation of the slurry to a density of at least 1750 kg/m3, the addition of potassium salts at N:P2O5:K2O ratios of 1:1:1, 1.5:1:1, and 1:1.5:1, product granulation, drying in the presence of recycle, and cooling.
