摘要: Though noise is traditionally considered detrimental to dynamical systems,noise can sometimes be utilized for advantageous purposes. By using thephenomenon of stochastic resonance as a motivation, several nonlinearsystems have been studied, by using analytical, numerical, and experimentalmethods. Different phenomena have been explored, including noise-inducedenergy attenuation, the effects of noise on the response near a bifurcation point,and stabilizing effects of noise. These studies could lay the foundation forconstructive use of noise and nonlinearity in a variety of systems, includingmechanical systems.
