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

The Main Function Of Drilling Fluid In Oil And Gas Well Drilling And Its Selection Depending On The Formation
Drilling fluid is a key element of the drilling system, providing load-bearing, transport, isolation, and information-diagnostic functions. The purpose of this paper is to systematically describe the main functions of drilling fluid and propose a scientifically based approach to its selection depending on the geological and technical conditions and properties of the target formation. The study provides a review of modern fluid classes (water- and oil/synthetic-based), their rheological and colloidal-chemical properties, and an analysis of critical scenarios: swelling clay formations, cavernously fractured carbonates with absorptions, salt formations, HPHT intervals, zones with H₂S/CO₂, water-cut and decompressed reservoirs. A multi-level selection methodology is proposed using (i) a geohazards decision matrix, (ii) laboratory tests (shale swelling, HPHT filtration, friction and lubrication, formation water/oil compatibility), (iii) hydraulic modeling (ECD, cuttings breakdown velocity, pressure profile), and (iv) an environmental and economic assessment of the full life cycle. The results are presented in the form of practical recommendations for the selection of formulations and modes for typical lithotypes. Limitations and directions for further research, including digital drilling twins and adaptive drilling fluids, are discussed
Modern Scientific Research On Noise Reduction In Production Processes
This article examines modern scientific research on the problem of noise and its reduction in industrial production processes, in particular, in machine-building workshops and related enterprises. Noise is one of the dangerous production factors in the occupational health and safety system, and its high level leads to a decrease in hearing, diseases of the nervous system, and a decrease in labor productivity in workers. Although world and national standards indicate that noise above 85 dBA contradicts regulatory requirements, in workshops using heavy mechanical equipment, indicators up to 95-100 dBA are observed. The article analyzes scientific research conducted in recent years and separately considers three main noise reduction strategies - direct impact on the noise source, the use of acoustic barriers in the path of propagation, and the use of personal protective equipment. The effectiveness of acoustic screens and absorbing panels, new types of noise-absorbing materials, vibrationreducing structural solutions, and protective equipment that meet ergonomic requirements were analyzed. It is also shown that special clothing and innovative solutions based on acoustic filtration have the possibility of application in the production environment. The results of the analysis show that in the fight against noise, it is not enough to take only one approach, but it is necessary to apply a set of measures. At the same time, the issues of integration with technological processes, economic efficiency, and material stability in high-temperature zones have not yet been fully resolved. In future scientific research, noise control in real time using intelligent control systems, the use of composite materials, and the development of environmentally safe solutions are proposed as promising areas.

Mathematical Modeling Of Energy Consumption And Separation Efficiency Of Multicyclones For Air Purification
Multicyclones—compact arrays of small-diameter cyclone cells—remain the work-horse technology for removing coarse dust from industrial exhaust streams thanks to their low capital cost and mechanical robustness. Their main drawbacks are the pressure drop that drives fan energy demand and the inherent trade-off between energy use and collection efficiency. This paper develops an integrated mathematical model that couples (i) gasdynamics-based correlations for pressure drop, (ii) Barth’s static-particle theory for grade efficiency, and (iii) a fan-power model to quantify specific energy consumption (SEC) per tonne of dust captured. A parametric simulation covering volumetric flow rates 0.05 – 0.8 m³ s⁻¹ per cell, cyclone diameters 0.1 – 0.3 m, and dust particle diameters 1 – 20 µm is implemented in Python/MATLAB. Results (Figure 1) show ΔP rising quadratically with superficial velocity, while the predicted collection curve (Figure 2) exhibits a typical Sshape with 50 % cut size d₅₀ ≈ 5 µm. The combined model reveals a sweet-spot operating window (5 – 8 m s⁻¹) where SEC is minimized without compromising ≥ 80 % overall efficiency. The framework provides a fast tool for optimising multicyclone banks in retrofits or green-field designs
Coordinated Integration And System Optimisation Of Air-Purification Technologies Through Mathematical Modelling
Growing public-health pressure for ultra-clean air has stimulated a shift from single-device solutions to integrated treatment trains that combine cyclones, wet scrubbers, electrostatic precipitators and fabric filters. We present a unified dynamic model that (i) couples particle, gas and energy balances across each module, (ii) embeds a finite-volume discretisation for axial dispersion, and (iii) links the sub-models with continuity conditions for mass-flow, temperature and pressure. A multi-objective NSGAII optimiser is wrapped around the model to maximise overall removal efficiency while minimising pressure drop and annualised operating cost. Simulations show that coordinated operation adds up to 27 % efficiency gain at equal pressure drop compared with the best single device. Two illustrative results are given in Figure 1 (efficiency versus flow rate) and Figure 2 (Pareto frontier).
