Impact of inclined double-cutoff walls under hydraulic structures on uplift forces, seepage discharge and exit hydraulic gradient

Ain Shams Engineering Journal, 2022
In hydraulic structures design, using cutoff walls is essential to reduce and control the resultant uplift force (U), seepage discharge (Q), and exit hydraulic gradient (i).

Effect of the existence of under drain on Uplift pressure and Exit Gradient.

Sulaimani Journal for Engineering Sciences, 2017
The effects of the existence of an under drain pipe beneath the foundation of a hydraulic structure, on both the uplift pressure under the structure and the exit gradient on its downstream side are investigated.

Improving Human Activity Recognition With Wearable Sensors Through BEE: Leveraging Early Exit and Gradient Boosting

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Early-exiting has recently provided an ideal solution for accelerating activity inference by attaching internal classifiers to deep neural networks. It allows easy activity samples to be predicted at shallower layers, without executing deeper layers ...

Analytical Solution for the Steady Seepage Field of an Anchor Circular Pit in Layered Soil

Buildings, 2023
An analytical study was carried out on an anchored circular pit with a submerged free surface in layered soil. The seepage field around the anchor circular pit was divided into three zones.

Reduction of Seepage Risks by Investigation into Different Lengths and Positions for Cutoff Wall and Horizontal Drainage (Case Study: Sattarkhan Dam)

Advances in Civil Engineering, 2022
Seepage from the earth dam’s body reduces the amount of water in the dam’s reservoir and threatens its stability. In this paper, the earth-type Sattarkhan Dam on the Aharchai River has been investigated.

Analysis of Non-Darcy Flow in Aquitard at Bottom of Foundation Pit Under Fluctuation of Confined Water

Shanghai Jiaotong Daxue xuebao, 2020
In order to better explain the phenomenon of foundation pit inrush caused by confined water, the Hansbo non-Darcy seepage theory was introduced into the Terzaghi one-dimensional saturated soil consolidation equation.

Exit Time Analysis for Approximations of Gradient Descent Trajectories Around Saddle Points

Information and Inference: A Journal of the IMA, 2022
AbstractThis paper considers the problem of understanding the exit time for trajectories of gradient-related first-order methods from saddle neighborhoods under some initial boundary conditions. Given the ‘flat’ geometry around saddle points, first-order methods can struggle to escape these regions in a fast manner due to the small magnitudes of ...
