Comprehensive Assessment Of The Impact Of Hydrogeological Factors On The Stability Of Open-Pit Slopes, Vokhid Rakhimovich Kadirov, Khurshida Yunusovna Norova, Zavkiddin Yahyo Oglu Ravshanov, Jamol Hasankhonovich Abdumalikov

Technical science and innovation

This paper presents an analysis of the influence of hydrogeological conditions on the stability of open pit slopes located within zones of tectonic disturbance. Based on field investigations and long-term hydrogeological monitoring conducted within the Almalyk ore cluster (Kalmakyr, Yoshlik-I, and Kurgashinkan deposits), the key factors affecting slope stability have been identified. It has been established that groundwater inflows from fractured and karstified Paleozoic rocks, as well as the presence of flooded abandoned pits, significantly increase the risk of slope deformation and failure. A special role is attributed to tectonic faults, which act as filtration channels for groundwater, leading to …

Algorithm For Stabilizing The Reference Trajectory Of Self-Tuning Systems With A Reference Model, Isamidin Hakimovich Sidikov, Feruzakhon Botirxon Qizi Sodiqova

Technical science and innovation

The paper addresses the problem of stabilizing self-tuning systems using adaptive control methods based on a reference process model. As the optimality criterion, the functional of maximum speed of response is selected. The algorithm for synthesizing the self-tuning system is based on a relay-linear control law, which possesses the property of invariance to small disturbances. The issue of ensuring the practical stability of the system under adaptive and multiplicative disturbances is examined. An algorithm for the synthesis of a reference trajectory stabilization system has been developed on the basis of a quasi-optimal passive self-tuning system (STS) with a reference model, …

Properties Of Shape Memory Alloys In Solving Design Problems, Aya Mahmoud Ad-El Gawad Gouda Dec 2025

Properties Of Shape Memory Alloys In Solving Design Problems, Aya Mahmoud Ad-El Gawad Gouda

Journal of Art, Design and Music

Shape Memory Alloys (SMAs) are a unique class of materials that possess the ability to return to a predefined shape when subjected to specific thermal or mechanical stimuli. This property, known as the "shape memory effect," arises from the transformation between two phases: the low-temperature martensite phase and the high-temperature austenite phase. SMAs have gained significant attention in various engineering fields, particularly in solving complex design problems that require materials with the ability to undergo reversible deformation. These alloys exhibit exceptional properties such as high strength, elasticity, and the ability to absorb significant amounts of energy, which make them ideal …

Journal of Roleplaying Studies and STEAM

En este trabajo abordamos, desde el punto de vista semiótico, el vínculo indisoluble que existe entre el cuerpo humano, la significación y la socialidad. Partimos del postulado de que el cuerpo es, desde el nacimiento, una entidad sintiente; luego, una vez adquirida la capacidad de generar procesos semiósicos primarios, empieza a ordenar y a clasificar los estímulos exteriores, hecho en el que se asienta el fundamento de su orientación básica en el entorno. Conforme aumentan sus competencias semiósicas, se incrementan sus capacidades perceptivas y cognitivas que, al ser afirmadas, lo llevan a alcanzar finalmente los más altos grados de socialidad. …

Mansoura Engineering Journal

This study introduces an operational evaluation of a deep learning–driven ionospheric modeling system tailored for Egypt, designed to overcome the limitations of conventional empirical approaches in data-sparse regions. The 3D-DNN Ion-EG model was trained on 737,110 COSMIC-2 radio occultation profiles (2020–2024), integrating spatial temporal coordinates with geophysical drivers to generate high-resolution threedimensional electron density distributions. Validation against the MANS CORS station (Mansoura University) demonstrated strong predictive skill (R2 = 0.9337; r = 0.970) under independent testing. Performance analysis across diverse geophysical regimes confirmed the model’s advantage in capturing storm-time and solar-driven disturbances, surpassing empirical models that perform best only under …

Structure Of Jupiter's High-Latitude Storms: Folded Filamentary Regions Revealed By Juno, L. N. Fletcher, Z. Zhang, S. Brown, F. A. Oyafuso, J. H. Rogers, M. H. Wong, S. Brueshaber, Et. Al

Michigan Tech Publications

Sprawling, turbulent cloud formations dominate the meteorology of Jupiter's mid‐to‐high latitudes, known as Folded Filamentary Regions (FFRs). A multi‐wavelength characterization by Juno reveals the spatial distribution, vertical structure, and energetics of the FFRs. The cloud tops display multiple lobes of stratiform aerosols, separated by darker, cloud‐free lanes, and embedded with smaller eddies and high‐altitude cumulus clouds. These cyclonic FFRs are microwave‐bright in shallow‐sounding wavelengths (p < 5 bars) and microwave‐dark in deep‐sounding wavelengths (p > 10 bars), with the transition potentially associated with the water condensation layer (6–7 bars). Associating microwave contrasts with temperature anomalies, this implies despinning of cyclonic eddies above/below their mid‐planes. Despite deep roots (being detectable in …

Mansoura Engineering Journal

The failure caused by punching shear is considered very dangerous because it happens suddenly. So, many researches have presented various methods to enhance the punching shear capacity by adding shear reinforcement like, vertical shear studs, stirrups or other means. In this study continuous stirrups is used as a shear reinforcement system. An experimental test includes four interior slab-column joints, of normal strength concrete, and an analytical study had been carried out to examine the efficiency of the proposed reinforcement system. The finite element analysis had been carried out by using computer program ABAQUS-V13.0 .The final results showed that, using continuous …

Lithium-ion (Li-ion) battery using a graphite (Gr.) anode and a lithium iron phosphate (LiFePO4, LFP) cathode (Gr.||LFP) has been widespread in energy storage. To match the warranty period of energy storage systems, the lifespan of this kind of Li-ion battery, not only under room temperature but also under relatively high temperature, is critical. Exploration of functional electrolyte additive provides an efficient approach to address this issue. This study reports the usage of pyridine (Py) as a new electrolyte functional additive for Gr.||LFP. In the first cycle, it was found that Py can be reduced before ethylene carbonate and …

Pressure Field Estimation From 2d-Piv Measurements: A Case Study Of Fish Suction-Feeding, Jensine C. Coggin, Duvall Dickerson-Evans, Erin E. Hackett, Roi Gurka

Physics and Engineering Science

Particle image velocimetry (PIV) flow measurements are common practice in laboratory settings in a wide variety of fields involving fluid dynamics, including biology, physics, engineering, and medicine. Dynamic fluid pressure is a notoriously difficult property to measure non-intrusively, yet its variation is a driving flow force and critical to model correctly. Techniques have been developed to estimate the pressure from velocity and velocity gradient measurements. Here, we highlight a novel application of boundary conditions when applying such pressure estimation techniques based on two-dimensional PIV data; the novel method is especially relevant to problems with complex boundary conditions. As such, it …

Mansoura Engineering Journal

In this work, three methods are proposed to identify parameters of PI controllers used for wind energy conversion systems based on DFIG. Mathematical model of generator and grid side system is depicted. Three tuning methods; bode-plot, pole-placement, and MATLAB tuner are used for grid side and rotor side converter controllers’ design. Wind turbine system with PI controller parameters obtained using the mentioned method is investigated via MATLAB/SIMULINK under three different scenarios. The wind system is subjected to step wind speed change, random wind speed, and sever symmetrical voltage dip in the grid. The handled comparison illustrates that the pole-placement tuning …
