Space-time discontinuous Galerkin method for the compressible Navier-Stokes equations on deforming meshes [PDF]
, 2006 An overview is given of a space-time discontinuous Galerkin finite element method for the compressible Navier-Stokes equations. This method is well suited for problems with moving (free) boundaries which require the use of deforming elements. In addition,

Deep Underground Science and Engineering, EarlyView.The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...

Reclaimed Homophobic Hate Speech Backfires: Desensitization and Mood Deterioration
European Journal of Social Psychology, EarlyView.ABSTRACT Reclaimed hate speech is generally seen as a positive phenomenon by minority groups and, to some degree, by majority groups. However, previous research has not examined whether it might produce harmful effects similar to traditional hate speech.
