Artificial Recharge Of Groundwater As A Solution To Water Scarcity In Uzbekistan
Groundwater resources in Uzbekistan are declining at an alarming rate. Monitoring data from 21 districts across the country indicate that water table levels have dropped by 5 meters or more, posing a serious threat to long-term water security and ecological stability. This study identifies the primary causes of groundwater depletion - including inefficient water use, the absence of water-saving irrigation technologies, and the misuse of drinking-quality water for non-potable purposes - and proposes targeted solutions. The central innovation proposed is the establishment of an Artificial Aquifer Recharge (AAR) system, through which surplus surface water is directed into underground layers during non-irrigation seasons. Additional measures include the mandatory installation of water meters at all abstraction points and the systematic adoption of drip irrigation across agricultural areas. Implementation of these integrated measures is projected to stabilize groundwater levels and secure water availability for future generations.1
Design And Hydrodynamics Theory Of A Device With A Fructose Cone Contact Element
The article theoretically presents the structure, operating principle and hydrodynamic resistance of an apparatus with a truncated conical contact element for wet cleaning of coke dust particles with an average size of 8.7 μm in 1 m³ of dusty gas. The design of the apparatus is formulated in the MATLAB programming environment based on parametric evaluation of gas consumption, liquid consumption, contact element geometry, free crosssectional area and the effect of a cyclonic droplet catcher. In the proposed solution, a liquid jet impinges on a truncated conical element located in the centre of the working chamber, forming a liquid screen, a layer of small droplets and a liquid film along the wall. As a result, the probability of dust particles coming into contact with water droplets and a liquid curtain increases.
Design and Mathematical Modeling of a Novel Angular Displacement Transformer for Accurate Diagnostics of Angular Displacements
This paper investigates the linear and nonlinear distributed-parameter circuits of a new resonant electromagnetic transducer intended for converting motion parameters (displacement and velocity) into electrical signals. It is shown that in the linear distributed-parameter circuit of the transducer, the magnetic flux and magnetic field intensity vary along the length of the circuit according to a nonlinear law; moreover, the degree of this nonlinearity increases with an increase in the attenuation coefficient of the magnetic field along the magnetic circuit. When the distributed-parameter magnetic circuit of the transducer operates in the nonlinear regime, achieving a linear distribution of the working magnetic flux along the circuit length requires that the working air gap between adjacent long ferromagnetic rods vary along the length of the circuit according to a prescribed law. In this case, the magnitude of the variation of the working magnetic flux along the circuit length does not depend on the value of the approximation coefficient characterizing the nonlinearity of the circuit.

District-Level Associations Between a Composite Environmental Pollution Index and Five EcologySensitive Disease Groups in the Aral Sea Region of Uzbekistan: A 2010– 2023 Ecological Study
The Aral Sea region of Uzbekistan — Karakalpakstan and Khorezm — experiences combined air, water and soil pollution from the desiccated seabed, saline drainage waters and legacy organochlorine pesticides. The cumulative impact on population health remains poorly quantified at sub-regional resolution. Objective. To examine, across 25 administrative districts, the association between a composite pollution index (CPI) and five ecology-sensitive disease groups: respiratory, cardiovascular, oncological, endocrine, and infant/maternal. Methods. An ecological cross-sectional design with longitudinal supplements was used. Age-standardised disease rates (2010–2023) were extracted from official registers. CPI was the unweighted mean of normalised US EPA AQI, CCME WQI and Håkanson–Müller soil indices. Spearman rank correlation and multivariable linear regression with sociodemographic adjustment were applied. Results. Disease rates were highest in Moynak — asthma 814, COPD 590, hypertension 2,840, IHD mortality 264, cancer 268 per 100,000 and infant mortality 24.8 per 1,000. CPI correlated with all five outcomes (r_s 0.70–0.82). Adjusted models confirmed the associations. Conclusions. Composite pollution is strongly and consistently associated with ecology-sensitive disease burden; multi-media mitigation in northern Karakalpakstan is urgent.
The History Of Judicial And Prosecutorial Institutions In The Republic Of Uzbekistan
The judicial and prosecutorial systems of Uzbekistan have evolved through distinct historical phases: pre-Soviet traditional justice rooted in Islamic shariah and customary law, the centralized Soviet socialist model (1924–1991), early post-independence continuity with limited reforms (1991–2016), and radical modernization since 2017 under President Shavkat Mirziyoyev. This article traces these developments, highlighting the shift from executive-dominated structures to a more independent judiciary aligned with democratic principles, rule of law, and international standards. It examines key legislative milestones, institutional changes, and ongoing challenges, drawing on constitutional, historical, and legal sources.

Evaluation of the Effect of the Microstructure of Glass Fiber and Polytetrafluoroethylene-Based Filter Fabric on Bag Filter Performance
This paper examines the microstructural parameters of filter fabric manufactured from a combination of glass fibers and polytetrafluoroethylene (PTFE) fibers and evaluates their effect on the performance of a bag filter unit. In the course of the study, filter fabric samples with thicknesses of 1.0 mm, 1.5 mm, and 2.0 mm were investigated by microscopic analysis at 100× magnification. For each sample, original micrographs, segmented images, and contour images were generated, and these were used to determine the values of the open area, closed area, and specific contact surface area. The analysis revealed that, as fabric thickness increased, porosity decreased, the fiber arrangement became denser, and the fraction of open channels was reduced. At the same time, the proportion of closed areas increased. The calculated values of the specific contact surface area showed a decreasing trend with increasing fabric thickness. The obtained results indicate that the microstructure of glass fiber–PTFE-based filter fabric is a significant factor governing the aerodynamic and filtration characteristics of a bag filter. According to the findings, the 1.5 mm-thick fabric may be regarded as the most favorable option, since it ensures a relatively optimal balance among the open area, closed area, and contact surface area.

“Modeling and Control of Induction Motor Using Indirect Field-Oriented Control (IFOC) with PWM-Based Voltage Source Inverter”
This thesis presents the modeling and control of an induction motor drive using the Indirect Field-Oriented Control (IFOC) strategy. The proposed system employs a decoupled control structure, allowing independent regulation of torque and flux components through dq-axis transformation. A closed-loop control scheme is developed, consisting of an outer speed loop and inner current control loops, implemented using PI controllers. The reference voltages are generated in the synchronous reference frame and applied to the motor through a PWM-based voltage source inverter. The proposed approach ensures fast dynamic response, precise speed regulation, and reliable operation, making it well suited for application in AC electric locomotive traction systems.

Place Of Earth Faults In Geology And Main Tectonophysical Indicators
It is difficult to limit the place of earth cracks in geology, no matter how high it is appreciated. It plays a key role in the formation of mineral deposits. Whether minerals are solid (gold, copper, aluminum, etc.), liquid or gaseous (groundwater, oil and gas), affects their location and migration. The structure of the geological environment, the course of the processes taking place in it, the increase or decrease in the amount of stress and deformation depend on the morphology, density and other parameters of the earth's cracks. Even the formation of earthquake foci is related to cracks. Therefore, the study of cracks is of great importance not only in mining and seismology, but also for solid construction - in the correct implementation of the engineering-geological conditions.

Autonomous Landing Site Detection & Safe Approach Path Planning for Personal Aerial Mobility Vehicles
As Personal Aerial Mobility (PAM) and Electric Vertical Take-off and Landing (eVTOL) aircraft are moving from just ideas to actual use, the reliance on fixed, pre-mapped infrastructure poses a significant barrier to global scalability. In regions with low infrastructure and harsh weather conditions such as Uzbekistan, the ability to perform autonomous, unplanned landings is critical [1]. This research suggests a solid framework for landing site selection and approach path generation, providing an innovative infrastructure for autonomous air mobility. The methodology utilizes a geometric filtering approach to process Digital Surface Models (DSM) and Digital Terrain Models (DTM), extracting slope and obstacle data to generate a Safety Score Map. This map serves as the cost-grid on A* search algorithm, ensuring a verifiable and optimal path to the safest identified landing zone [1][3]. Throughout the research several contributions like the development of a real-time autonomous scoring metric, dynamic route planning via grid-based optimization, and sensing analytics for trustworthy decision-making in unstructured environments is needed. Experimental evaluation within a high-fidelity simulation environment demonstrates that this simple geometric approach achieves high precision in obstacle avoidance and landing site accuracy, providing a transparent alternative to complex, black-box deep learning systems [1][2].

The Concept of a Greenhouse with Intelligent Microclimate Control and Near-Zero Energy Consumption: Renewable Energy, Accumulation, and Designed Thermal Balance
This article presents a scientific and applied concept of a new generation greenhouse with intelligent microclimate control (Smart Greenhouse AI) and near-zero energy consumption (Near-Zero-Energy Greenhouse, NZEG). The main focus is on the integration of renewable energy sources – solar, geothermal, and wind – with heat storage systems and artificial intelligence for adaptive control of heat flows. The use of predictive algorithms based on neural networks and a digital twin of the microclimate allows for stabilizing temperature and humidity with minimal energy costs. Simulation results in MATLAB Simulink show that the application of AI control reduces electricity consumption by 35–45%, reduces temperature deviations by 70%, and increases resistance to external disturbances. The proposed concept defines the engineering foundations of future greenhouses that comply with the principles of sustainable agriculture and "smart" energy systems.

Self-Optimization of Industrial Technological Processes Based on Digital Twin and Edge AI: From RealTime Monitoring to Predictive Control
The convergence of Digital Twin (DT) technology and Edge Artificial Intelligence (Edge AI) is transforming industrial automation from reactive monitoring into predictive, selfoptimizing control. This paper proposes an integrated framework in which a real-time digital twin continuously mirrors the physical process while an edge-deployed AI agent executes adaptive optimization locally. The model is built upon state-space representation, reinforcement-learning-based parameter tuning, and predictive fault diagnostics. MATLAB simulations demonstrate that coupling DT with Edge AI reduces steady-state error by more than 70 %, improves response speed by 2.4 times, and decreases energy consumption by approximately 25 %. Real-world evidence from process industries confirms the feasibility of this hybrid approach, marking a critical step toward resilient, autonomous manufacturing systems under the paradigm of Industry 5.0
