The article analyzes issues related to improving the operational reliability of centrifugal pumps widely used in the mining industry. It has been established that the primary causes of failures in pumping equipment operating in hydrotransport systems are hydro...
The article presents ideas on installing bushings made of rubber with elastic elements in the bearing housings of the roller mechanism of the belt conveyor, which provide a smooth rotational movement. In addition, methods for developing and calculating a resou...
Enhancing heat transfer efficiency in energy systems is a critical scientific challenge. The relatively low thermal conductivity of conventional heat transfer fluids limits the intensity of heat exchange processes. In this study, classical theoretical models w...
It is known that, despite the high accuracy of water balance forecasting, existing models such as AquaCrop, SWAP and HYDRUS do not fully take into account the relationship between water - salt balance and the effect of temperature limitations on root growth. M...
The uneven distribution of loads across phases in low-voltage power supply networks significantly affects the quality of electricity, voltage regimes, and power losses. This article presents a comparative analysis of the influence of symmetrical and asymmetric...
This paper presents the development of an automatic fruit sorting system based on color characteristics using an Arduino microcontroller and a TCS230 color sensor. The proposed system is designed to detect external color features of fruits in real time, proces...
In this study, the physico-mechanical and thermal properties of polyethylene modified with zinc terephthalate were studied. The use of modifiers in the production of polymer composite materials allows for a significant improvement in the operational properties...
This article examines the problem of determining hydraulically stable cross-sections for open channels. The potential of using the shear stress method to ensure the scour resistance of the channel bed and banks is analyzed. The shear stress method is based on ...
The article is devoted to the analytical calculation of the main parameters and dimensions of a pneumatic-hydraulic damper of hydraulic shock with pressure reduction, installed at the beginning of a pressure pipeline to reduce the emergency consequences of the...
This article analyzes the effect of pressure (0.1 – 100 MPa) and temperature (20 – 250°C) on the properties of technological fluids (HCl, water) and reaction products ( 𝐶𝑎𝐶 𝑙 2 , 𝑀𝑔𝐶 𝑙 2 , 𝐶 𝑂 2 , 𝑁 2 ) during acid treatment of carbonate reservoirs. Studies sh...
Using the central part of the Chardzhou stage as an example, the results of zoning the territory by the ratio of structural plans of carbonate and terrigenous deposits are presented, with the identification of 9 types of zones in the paper. Based on the analys...
This article presents theoretical studies aimed at reducing soil compaction caused by the tires of four-wheel tractors used in vegetable cultivation and harvesting under the soil and climatic conditions of our republic. The paper describes the structural desig...
This article examines the issues of improving the efficiency of chemical treatment of productive formations in oil and gas wells. Due to the shortage of hydrochloric acid and the increase in its cost, the possibility of using phosphoric acid for treating produ...
This study investigates the technology for obtaining a bioactive supplement from pomegranate peel (Punica granatum L.), a widely cultivated fruit in the climatic conditions of Uzbekistan. To maximize the extraction of polyphenols, ellagic acid, tannins, and ot...
This article analyzes the main external and internal factors affecting measurement processes in GPS navigation systems. Particular attention is paid to the sources of uncertainty that influence the accuracy and reliability of positioning results. The effects o...
The development of the multimodal transport system in Uzbekistan in recent years has been linked to the growth of freight volumes, the strengthening of intermodal connectivity, and the increasing demand for logistics services. Between 2020 and 2024, the total ...
The most important feature of artificial neural networks, which indicates the wide capabilities and enormous potential, is the parallel processing of information by all parts. A large number of connections between neurons allows you to significantly speed up t...
The increase in electric vehicles has made ensuring energy balance at charging stations a critical challenge. In this study, a hybrid model based on solar panels, wind turbines, the central grid, and battery storage was developed, and its efficiency was evalua...
Under the influence of the vortex zone formed at the confluence of two channels, sediments intensively settle. Taking these sediments into account, the hydraulic and geometric parameters of the flow are determined. The analytical solution shows that at the con...
