Analysis of Elastoplastic Mechanical Properties of Non-Uniform Frozen Wall Considering Frost Heave
Applied Sciences, 2023 The aim of this study was to analyze the force and deformation law of an artificial frozen wall. Thus, the frost heave coefficient was introduced to describe the frost heave characteristics, and the frozen wall was regarded as a heterogeneous material ...

On the Radius-Edge Condition in the Control Volume Method [PDF]
SIAM Journal on Numerical Analysis, 1999 The authors show that the control volume algorithm for the solution of the Dirichlet problem attached to the Poisson equation in three dimensions converges even if the mesh contains a class of very flat tetrahedra (slivers). They also show that a discrete Poincaré inequality continues to hold in the presence of slivers.

Where is the Inner Edge of an Accretion Disk Around a Black Hole? [PDF]
, 2002 What is meant by the "inner edge" of an accretion disk around a black hole depends on the property that defines the edge. We discuss four such definitions using data from recent high-resolution numerical simulations.

Compass radius estimation for improved image classification using Edge-SIFT [PDF]
Neurocomputing, 2016 The combination of SIFT descriptors with other features usually improves image classification, like Edge-SIFT, which extracts keypoints from an edge image obtained after applying the compass operator to a colour image. We evaluate for the first time, how the use of different radii in the compass operator affects the classification performance.

An Innovative Experimental Study of Corner Radius Effect on Cutting Forces [PDF]
, 2014 The cutting forces are often modelled using edge discretisation methodology. In finish turning, due to the smaller corner radii, the use of a local cutting force model identified from orthogonal cutting tests poses a significant challenge. In this paper,

Spectral Radius, Edge-Disjoint Cycles and Cycles of the Same Length
The Electronic Journal of Combinatorics, 2022 In this paper, we provide spectral conditions for the existence of two edge-disjoint cycles and two cycles of the same length in a graph, which can be viewed as the spectral analogues of Erdős and Posa's condition and Erdős' classic problem about the maximum number of edges of a graph without two edge-disjoint cycles and two cycles of the same length,
