The effects of using both directions and directional subdividing on adaptive gridembedding on the computational time and the number of grid points required for the same accuracy are considered. Directional subdividing is used from the beginning of the adaptation procedure without any restriction. To avoid the complication of unstructured grid, the semi-structured grid was used. It is used to so...

An explicit algorithm that yields finite difference schemes of any desired order of accuracy for solving quasi-linear hyperbolic systems of partial differential equations in several space dimensions is presented. These schemes are shown to be stable under certain conditions. The stability conditions in the one-dimensional case are derived for any order of accuracy. Analytic stability proofs for...

The article discusses substantiating the parameters brake system of a tractor-trailer (TT). section offers comparative analysis theoretical and experimental studies TT drive its elements. Based on that, ordinary differential equations were solved by Runge - Kutta method, first-order accuracy (Euler's method). To solve partial equations, we used modified Lax Wendroff scheme. results obtained usi...
