A Novel Surface Subsidence Prediction Model Based on Stochastic Medium Theory for Inclined Coal Seam Mining

Advances in Civil Engineering, 2023
Most coal resources are deposited in the form of inclined coal seams, and surface subsidence basin morphology induced by the mining of inclined coal seams is frequently skewed. The probability integral method with symmetrical distribution characteristics

ASPECTS AND GEOMETRIC INTERPRETATION IN SOLVING CONICAL SECTIONS

Journal of Industrial Design and Engineering Graphics, 2019
In mathematics, a conic is the curve that is obtained by intersecting a plane with a cone. Is well known that the shape of this curve may differ quite a bit depending on the position of the intersection plane relative to the cone axis, as it is actually ...

Bubble Movement on Inclined Hydrophobic Surfaces

Langmuir, 2017
The movement of a single air bubble on an inclined hydrophobic surface submerged in water, including both the upward- and downward-facing sides of the surface, was investigated. A planar Teflon sheet with an apparent contact angle of a sessile water droplet of 106° was used as a hydrophobic surface. The volume of a bubble and the inclination angle of a

Experimental and numerical investigation of the influence of relative density on the behavior of ring footings on an inclined surface [PDF]

Engineering and Technology Journal
Ring footings are a crucial foundation type for supporting large and tall structures, as they enhance structural stability, mitigate the risk of overturning, and resist lateral forces.

Stability analysis of soft–hard-interbedded anti-inclined rock slope

Scientific Reports, 2023
The instability of rock slope is still a very frequent geological disaster, which seriously affects people's life and production activities. Previous studies have mainly focused on deformation mechanism, prediction, and control of hard rock with single ...

Numerical Solution of Casson Nanofluid Flow Over a Non-linear Inclined Surface With Soret and Dufour Effects by Keller-Box Method

Frontiers in Physics, 2019
In this article, the effects of a Casson Nanofluid boundary layer flow, over an inclined extending surface with Soret and Dufour, is scrutinized. The model used in this study is based on the Buongiorno model of the thermal efficiencies of the fluid flows

Selecting Surface Inclination for Maximum Solar Power

Energies, 2022
Maximum efficiency of surfaces that exploit solar energy, including Photovoltaic Panels and Thermal collectors, is achieved by installing them in a certain inclination (tilt). Most common approach is to select an inclination angle equal to the location’s latitude.
