Abstract : Moment closures were developed for modeling the transition regime in kinetic theory. This was done using a systematic nonperturbative derivation of a hierarchy of closed systems of moment equations. Criteria were developed regarding the stability of shocks in magnetohydrodynamics. Finally, the new insight was gained into the diffraction effects that occur when a weak shock interacts with a sharp wedge, the von Neumann paradox.
