A Mathematical Approach for Evaluation of Surface Topography Parameters

A. K. Haghi

Abstract


The probability characteristics of surface topography parameters described by the composition of the deterministic component and the homogeneous random normal field were analysed. Formulae for the calculation of the mathematical expectation of the Ras parameter and the evaluation of its variance are given.

Keywords
