Hydrodynamics of a Granular Gas in a Heterogeneous Environment

open access: yesEntropy, 2017
We analyze the transport properties of a low density ensemble of identical macroscopic particles immersed in an active fluid. The particles are modeled as inelastic hard spheres (granular gas).

Comparative Evaluation of the Fast Marching Method and the Fast Evacuation Method for Heterogeneous Media

open access: yesApplied Artificial Intelligence, 2021
The evacuation problem is usually addressed by assuming homogeneous media where pedestrians move freely in the presence of several exits and obstacles.

Viscoelastic Behavior of Heterogeneous Media [PDF]

open access: yes, 1965
The macroscopic viscoelastic behavior of linear viscoelastic heterogeneous media is defined in terms of effective relaxation moduli and creep compliances.

Finite-Difference Analysis of Influence of Borehole Diameter and Spacing on Reduction in Rockburst Potential of Burst-Prone Coal Seams

open access: yesMining
Decreasing the rockburst potential in longwall mining of burst-prone coal seams has been a longstanding challenge for geotechnical engineering worldwide.

Nonlocal peridynamic method for porous media seepage simulation

open access: yesRock and Soil Mechanics, 2021
Based on the establishment of peridynamic nonlocal porous media seepage model, several kernel functions reflecting the degree of nonlocal effect are introduced to improve the calculation accuracy, and the peridynamic permeability coefficients ...

Power law singularity of catastrophic rupture in heterogeneous media [PDF]

open access: yes, 2009
Catastrophic rupture in heterogeneous media, such as earthquake in crust, has long been a topic of scientific and societal importance. However, there has been no reliable approach to its prediction.

Stability of Breathers for a Periodic Klein–Gordon Equation

open access: yesEntropy
The existence of breather-type solutions, i.e., solutions that are periodic in time and exponentially localized in space, is a very unusual feature for continuum, nonlinear wave-type equations.

A simple P-wave polarization analysis: its application to earthquake location

open access: yesAnnals of Geophysics, 1994
We present a method for hypocentral location which takes into account all three components of ground motion and not only the vertical one, as it is usually done by standard least-square techniques applied to arrival times.

A mass-conservative control volume-finite element method for solving Richards’ equation in heterogeneous porous media [PDF]

open access: yes, 2011
We present a mass-conservative vertex-centred finite volume method for efficiently solving the mixed form of Richards’ equation in heterogeneous porous media.
