On global dynamics of 2D convective Cahn–Hilliard equation

Abstract

In this paper, we study the long time behavior of solution for the initial-boundary value problem of convective Cahn–Hilliard equation in a 2D case. We show that the equation has a global attractor in $H^{4}(\Omega )$ H 4 ( Ω ) when the initial value belongs to $H^{1}(\Omega )$ H 1 ( Ω ) .

Grade prediction of rock burst based on PSO-RVM model

“…The brittleness coefficient R and the brittleness index U K are acquired from the perspectives of strength and deformation, respectively. Here, R is the ratio of uniaxial compressive strength to tensile strength, and U K denotes the ratio of total deformation before peak strength to permanent deformation [14]. Generally, the brittleness of rock mass is proportional to the possibility of rock burst occurring.…”
