Nonlinear Spinor Field in Non-Diagonal Bianchi Type Space-Time
EPJ Web of Conferences, 2018 Within the scope of the non-diagonal Bianchi cosmological models we have studied the role of the spinor field in the evolution of the Universe. In the non-diagonal Bianchi models the spinor field distribution along the main axis is anisotropic and does ...

Contact problem of torsion of a multilayer base with elastic connections between layers
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014 Torsion of a multilayer base with elastic connections between layers by cylindrical punch with a flat sole was considered. The Hankel integral transform of the first order and the method of the compliance functions were used.

Fast rapidly convergent penetrable scattering computations
Advanced Modeling and Simulation in Engineering SciencesWe present a fast high-order scheme for the numerical solution of a volume-surface integro-differential equation. Such equations arise in problems of scattering of time-harmonic acoustic and electromagnetic waves by inhomogeneous media with variable ...
