Did you know?
WebJul 9, 2024 · The effect of noise strength on increasing the peak amplitude of the oscillations is prominent near the Hopf bifurcation (weak values of W E E), but very weak far from it. For strong noise [(e) and (f)], the amplitude peak and variability increase again for all W E E. Other parameters are as in Fig. 1. Reuse & Permissions WebWo study Hopf-Andronov bifurcations in a class of random differential equations (RDEs) with bounded noise. Wo observe that when an ordinary differential equation that undergoes a Hopf bifurcation is subjected to bounded noise then the bifurcation that occurs involves a discontinuous change in the Minimal Forward Invariant sot.

When a system prior to a Hopf bifurcation is exposed to a sufficient level of noise, its noise-induced dynamics can provide valuable information about the impending bifurcation. In this thesis, we present a system identification (SI) framework that exploits the noise-induced …

By using the Hopf bifurcation theorem we prove the occurrence of the Hopf bifurcation. And then, based on the normal form method and the center manifold reduction introduced by Hassard et al.,[10], we derive the formulae determining the direction, stability and the period of the bifurcating periodic solution at the critical ...
