The present study considers the application of stochastic dimensional reduction (low-dimensional approximation of stochastic dynamical systems) to a 11-dimensional nonlinear aeroelastic problem exhibiting a Hopf bifurcation, with one critical mode an

This paper develops multi-scale data assimilation/filtering algorithms that are driven by the data, that take advantage of scale interaction to appropriately reduce the dimension of the problem. We incorporate an optimal particle filtering algorithm

In this paper, we shall re-examine the stochastic version of the Duffing-van der Pol equation. As in [2], [9], [19], [22], we shall introduce a multiplicative and an additive stochastic excitation in our case, i.e.x¨=(α+σ1ξ1)x+βx˙+ax3+bx2x˙+σ
