This article investigates the impact of various planting systems and densities on the leaf formation dynamics of sweet potato grown in open fields and under film mulch in Uzbekistan. The research results indicate that the film mulch cultivation system accelera...
This paper analyzes the flow behavior of gas – liquid mixtures in pipelines and reviews modern approaches to hydraulic calculations of two-phase flows. The main hydrodynamic and thermodynamic factors affecting the transportation of gas, oil, condensate, and wa...
Reliable prediction of channel bed deformation is essential for the hydraulic design, rehabilitation, and operation of irrigation canals with weakly cohesive beds. However, the presence of both suspended sediment and a small proportion of cohesive material com...
This study presents a comprehensive three-dimensional coupled numerical model for a solar-driven desalination device incorporating a capillary-structured porous membrane (CPM). The governing equations - encompassing conjugate heat transfer, capillary-driven ma...
This article investigates the hydrological indicators of the Kamashi Reservoir and their impact on the meliorative condition of lands within its zone of influence. During the study, the reservoir water level, water storage volume, groundwater depth, and the so...
In tasks of identifying relationships between technological parameters of automated control objects, the capabilities of neural networks are used. One of the important problems considered in such identification tasks is the choice of the neural network archite...
This paper presents the theoretical framework and practical computational methods for estimating bed-load and suspended-load sediment transport rates in a trapezoidal open channel with asymmetric side slopes (m 1 ≠ m 2 ) on non-cohesive granular beds. Four cla...
This paper presents an improved numerical method for calculating water hammer in pressurized pipelines under conditions of flow discontinuity and volumetric cavitation. The physical nature of the water hammer phenomenon is analyzed, and the main factors affect...
In this article, the channel deformation processes in the Amu – Bukhara Machine Canal and the main factors causing them were identified through field investigations and hydraulic modeling. The research results showed that during the period from January to June...
This study investigates the dynamic adsorption of petroleum hydrocarbons in an organobentonite adsorption bed for the effective treatment of oil-contaminated water. Experimental investigations were carried out in a continuous-flow fixed-bed column system. The ...
Abstract. Cotton processing waste (husks and stalks) in Uzbekistan represents a significant renewable raw material for lignin production, the basis of thermo- and salt-resistant drilling fluid reagents. The choice of lignin extraction method affects its purity...
The article presents the results of practical work on the effective drilling of salt layers that form an aggressive environment and the qualitative reinforcement of well walls. The types, properties, and parameters of tommanage solutions used for geologically ...
The article presents the results of a 3D geological model of the Sherkent oil and gas field, created using Schlumberger’s Petrel software. The Sherkent structure was prepared for exploratory drilling in 2007 based on the interpretation of 3D seismic survey dat...
The paper presents the results of studying the fracturing and reservoir properties of rocks based on well logging data. Standard well logging methods (WLM – acoustic, neutron - gamma, gamma - gamma density, electrical and induction logging) were used to determ...
This article analyzes the theoretical foundations, technological approaches, and practical effectiveness of using energy-efficient materials in construction processes. Enhancing energy efficiency, minimizing heat loss, lowering the operational costs of buildin...
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...
This paper explores methods for analyzing automatic control systems (ACS) and optimizing controller parameters using the Python programming language. A third-order dynamic model of a heat exchanger is adopted as the research object. The study presents algorith...
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...
