This ebook summarizes the advancements in stochastic research and estimation. It provides novel functions to sensible difficulties in mechanical platforms. the most elements of the direction are random vibrations of discrete and non-stop platforms, research of nonlinear and parametric structures, stochastic modelling of fatigue harm, parameter estimation and id with functions to motor vehicle highway platforms and method simulations through autoregressive versions. The contributions could be of curiosity to engineers and examine staff in industries and universities who wish first hand info on current tendencies and difficulties during this topical box of engineering dynamics.
