TLDR
The first observation of stochastic resonance in an optical device, the bidirectional ring laser, is reported and the addition of injected noise can lead to an improved signal-to-noise ratio.Abstract:
We report the first observation of stochastic resonance in an optical device, the bidirectional ring laser. The experiment exploits a new technique to modulate periodically the asymmetry between the two counter-rotating lasing modes. The measurements verify that the addition of injected noise can lead to an improved signal-to-noise ratio (relative to that observed with no externally injected noise).read more

An adaptive fractional stochastic resonance method based on weighted correctional signal-to-noise ratio and its application in fault feature enhancement of wind turbine.
TL;DR: Wang et al. as discussed by the authors proposed an adaptive fractional stochastic resonance (SR) method based on weighted correctional signal-to-noise ratio (WCSNR) to enhance the weak fault feature of wind turbine under strong noise.

Stochastic resonance in a sinusoidal potential system: An analog simulation experiment
TL;DR: An analog simulation experiment is setup to verify the occurrence of stochastic resonance in an underdamped sinusoidal potential system driven by a periodic force and a Gaussian white noise and uses the mean hysteresis loss as a quantifier.

A high dimensional stochastic resonance system and its application in signal processing
TL;DR: In this article , a high-dimensional stochastic resonance (SR) model is proposed to explain the SR phenomenon from the perspective of equilibrium point which is driven by the input signal.

Characteristic periodicities of collective behavior at the foreign exchange market
Akihiro Sato,Janusz A. Hołyst +1 more
TL;DR: In this paper, the agent-based model of a financial market in which N market participants trade M financial commodities is considered. And the relationship among these characteristic periodic behaviors may be associated with a special structure where market participants perceive such information in the foreign exchange market.
