background : infertility causes psychological and emotional tension in the couples and makes severe stress on infertile men and women. relaxation technique is one of the methods that reduces the stress and can balance the human’s emotions. this study aimed to determine the effect of relaxation on the infertile women’s stress score. methods : this was a semi-experimental and clinical trial study...

We design and analyze a Schwarz waveform relaxation algorithm for domain decomposition of advection-diffusion-reaction problems with strong heterogeneities. The interfaces are curved, and we use optimized Ventcell transmission conditions. We analyze the semidiscretization in time with discontinuous Galerkin as well. We also show two-dimensional numerical results using generalized mortar finite ...

We investigate a high-order, fully explicit, asymptotic-preserving scheme for a kinetic equation with linear relaxation, both in the hydrodynamic and diffusive scalings in which a hyperbolic, resp. parabolic, limiting equation exists. The scheme first takes a few small (inner) steps with a simple, explicit method (such as direct forward Euler) to damp out the stiff components of the solution an...

We present and analyze waveform relaxation variants of the Dirichlet-Neumann and NeumannNeumann methods for parabolic problems. These methods are based on a non-overlapping spatial domain decomposition, and each iteration involves subdomain solves with Dirichlet boundary conditions followed by subdomain solves with Neumann boundary conditions. However, unlike for elliptic problems, each subdoma...
