The effects of graphite and hexagonal boron nitride (h-BN) as solid lubricants and aluminum oxide (Al2O3) and boron carbide (B4C) as abrasives on brake friction performance were evaluated. Friction material samples were produced based on an experimental formulation, and the lubricants and abrasives were added to the r…

We consider a uniform finite difference method on an S-mesh (Shishkin type mesh) for a singularly perturbed semilinear one-dimensional convection–diffusion three-point boundary value problem with zeroth-order reduced equation. We show that the method is first-order convergent in the discrete maximum norm, independentl…

The paper considers finite difference approximations of arbitrary order $O(\tau ^n )$ to certain nonhomogeneous singular perturbation problems involving a small coefficient $\varepsilon ^2 $ in the higher derivative, where $\tau $ is the length of the discretization step in t and n is an arbitrary integer fixed in adv…
