Exit Gradient in Anisotropic Porous Medium

Journal of Hydraulic Engineering, 1983
The inclination of flow lines at the exit on the downstream side of a hydraulic structure has been found for a known degree of anisotropy and a given direction for the principal permeability. An analytical procedure is presented to find the exit gradient for steady confined flow in an anisotropic porous medium from known exit gradient of the ...

Probabilistic Analysis of Exit Gradients due to Steady Seepage

Journal of Geotechnical and Geoenvironmental Engineering, 1998
The traditional approach for estimating the exit gradient \ii\i\de downstream of water retaining structures due to steady seepage is to assume homogeneous soil properties and proceed deterministically, perhaps using flow-net techniques. Once the exit gradient is estimated, a large safety factor of at least five or six is applied.

Uplift force, seepage, and exit gradient under diversion dams

Proceedings of the Institution of Civil Engineers - Water Management, 2013
Correct estimation of uplift force, seepage discharge and exit gradient is very important in stability analysis of hydraulic structures. In this research, by carrying out a set of experiments on a laboratory model, the application of various methods for estimating uplift pressure and seepage discharge under hydraulic structures, and the exit gradient ...

Effect of Varying Geometrical Configuration of Sheet Piles on Exit Gradient and Uplift Pressure

2018
Seepage becomes an inevitable concern when dealt with earthen dams, as the impounded water seek paths of least resistance through the dam and its foundation. Seepage, if uncontrolled, can erode soil from the embankment or foundation causing progressive or rapid erosion and piping of the embankment or foundation soils.

Abstract 14985: Presence of Repolarization Gradients Reverses Post-infarct Ventricular Tachycardia Exit and Entrance Sites in Personalized Digital Hearts

Circulation, 2020
Introduction: Post-infarct ventricular tachycardias (VT) arise due to structural remodeling (scarring). Physiological repolarization gradients (apicobasal and transmural) exist in the human heart, but the effects on post-infarct VT dynamics are unknown.

Separate Reverse: A Gradient-Conflict-Free Training Framework for Multi-Exit Transformers

Web Intelligence
Pretrained transformer models have demonstrated excellent performance on complex tasks. To improve their inference efficiency, recent studies have introduced the multi-exit mechanism, which enables early exiting through multiple intermediate classifiers.

Collaborative effects of vehicle speed and illumination gradient at highway intersection exits on drivers’ stress response capacity

Accident Analysis & Prevention
Inadequate visibility is a critical factor contributing to the heightened occurrence of nighttime accidents at highway intersections. The installation of smart streetlights which are equipped to detect vehicle positions and speed information, thereby dynamically adjusting illumination, offers a promising solution to significantly reduce nighttime ...

Induced pressure gradients due to entrance and exit effects in electroosmotically driven flows through nanopores within the continuum regime

Journal of Physics D: Applied Physics, 2008
In this paper, a theoretical model is devised for analysing the effects of induced pressure gradients on electroosmotically driven nanopore flows within the continuum regime, without presuming the validity of the Boltzmann distribution of ionic charges. The charge density distributions are obtained from the conservation considerations of the individual

Performance of gas saturators in the presence of exit stream temperature gradients and implications for chemical vapor deposition saturator design

Chemical Engineering Science, 1994
When a carrier gas is passed through a gas saturator at temperature T0 containing liquid or solid reagent under conditions leading to its saturation with an equilibrium vapor pressure p∘ of the reagent, and then into a tube where the exit stream temperature is increased to T∞, the downstream partial pressure of reagent, p∞, may be less than p∘ due to ...

Effects of blanket, drains, and cutoff wall on reducing uplift pressure, seepage, and exit gradient under hydraulic structures

2015
Upstream blankets, drains and cutoff walls are considered as effective measures to reduce seepage, uplift pressure and exit gradient under the foundation of hydraulic structures. To investigate the effectiveness of these measures, individually or in accordance with others, a large number of experiments were carried out on a laboratory model.
