The issues of spurious residual oscillations in the displacement laws of cam systems
The paper deals with spurious residual oscillations and compensation methods in the rest areas of the displacements laws of cam system working links. Currently, cam mechanisms are divided into two basic groups, depending on how exci...

On spurious oscillations at layers diminishing (SOLD) methods for convection-diffusion equations: Part II - Analysis for P1 and Q1 finite elements
The most promising SOLD methods are investigated for P1 and Q1 finite elements. In particular, the dependence of the results on the mesh, the data of the problems and parameters of the methods are studied analytically and numerically....
