Non-linear stochastic systems are at the centre of many engineering disciplines and progress in theoretical research had led to a better understanding of non-linear phenomena. This work provides information on new fundamental results and their applications which are beginning to appear across the entire spectrum of mechanics. Theoutstanding points of these proceedings are a coherent compendium of the current state of modelling and analysis of non-linear stochastic systems from engineering, applied mathematics and physics point of view. Subject areas include: multiscale phenomena, stability and bifurcations, control and estimation, computational methods and modelling.
