Mechanical Stochastic Resonance
Stochastic resonance is a nonlinear phenomenon in which noise can paradoxically enhance a weak periodic signal. It has been implicated in a diverse range of phenomena, from the ice ages of Earth to the transduction of hair cells. We are attempting to experimentally realize stochastic resonance (and the related phenomenon of noise enhanced propagation) in a mechanical system consisting of an inverted pendulum coupled to the irregular flapping of a flag being blown by a jet fan. We have qualitatively observed the phenomenon but need to improve the apparatus and the data.
Physics, Mathematics, Computer Science
Careful assembly and tweaking the design of the apparatus, using software like Igor Pro and Mathematica to analyze the data.
