Abstract We study model theory of fields with actions a fixed finite group scheme. prove the existence and simplicity companion such actions, which generalizes our previous results about truncated iterative Hasse–Schmidt derivations [13] Galois [14]. As an application methods, we obtain new complete on imperfection degree.

In this paper, transverse and longitudinal vibration of nonlinear plate under exciting of orbiting mass is considered based on first-order shear deformation theory. The nonlinear governing equation of motion are discretized by the finite element method in combination with Newmark’s time integration scheme under von Karman strain-displacement assumptions. For validation of method and formulation...

Abstract. We present a finite volume scheme for ideal compressible magnetohydrodynamic (MHD) equations on 2-D Cartesian meshes. The semi-discrete scheme is constructed to be entropy stable by using the symmetrized version of the equations as introduced by Godunov. We first construct an entropy conservative scheme for which su cient condition is given and we also derive a numerical flux satisfyi...

in this paper a novel numerical approach is presented for solving the transient incompressible fluid flow problems with free surfaces in generalized two-dimensional curvilinear coordinate systems. solution algorithm is a combination of implicit real-time steps and explicit pseudo-time steps. governing fluid flow equations are discretized using a collocated finite-volume mesh. convective terms a...
