Stress distribution inside a powder bed: does Janssen’s model applicable locally in a granular medium

always an effect of cohesion on the maximum angle of stability. This regime has been called the “gran- ular regime” according to Tegzes experiments in which a cohesion effect on

(see also the numencal work in reference [12]), which shows that the vertical component of trie force beneath a sand heap bas a double-belled shape, with a local minimum at trie

This- siniilarity between the structure and velocity distribution of the granular fluid and the usual hard disk fluid suggests that the kinetic theory of Jenkins [9] is applicable.

The limit of the initial energy for the solution Ψ ε of the wave equation (38) is given by Lemma 6.3 and it coincides with the sum of the initial energies of the homogenized

In this system the light field that probe the atoms deep inside the porous medium is strongly scattered by the medium and have a propagation direction, amplitude and phase

For comparison, we have measured fluorescence decay-times in a Rb vapor cell with no porous medium where no bound of τ ′ was reached (Fig. Color online a) Photon count rate versus

However, even for 2D patterns, the spatial variability of ripples formed by a monochromatic gravity wave of high quality in a flume suggests that statistics on distributions of

In any computable probability space, a point is Schnorr random if and only if it is typical for every mixing computable dynamical system.. The paper is organized as follows: Section
