A novel image noise reduction method for composite multistable stochastic resonance systems [PDF]

open access: yesHeliyon, 2023
In the field of digital signal processing, image denoising is an more and more significant research direction. For the traditional noise reduction theory, noise is considered to be harmful, and the image quality can be improved by analyzing noise ...

Entropic Stochastic Resonance [PDF]

open access: yesPhysical Review Letters, 2008
We present a novel scheme for the appearance of Stochastic Resonance when the dynamics of a Brownian particle takes place in a confined medium. The presence of uneven boundaries, giving rise to an entropic contribution to the potential, may upon ...

Magnetic Anomaly Detection Based on a Compound Tri-Stable Stochastic Resonance System [PDF]

open access: yesSensors, 2023
In the case of strong background noise, a tri-stable stochastic resonance model has higher noise utilization than a bi-stable stochastic resonance (BSR) model for weak signal detection.

Stochastic resonance in electrical circuits—I: Conventional stochastic resonance. [PDF]

open access: yesIEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 1999
Stochastic resonance (SR), a phenomenon in which a periodic signal in a nonlinear system can be amplified by added noise, is introduced and discussed. Techniques for investigating SR using electronic circuits are described in practical terms.

Signal-to-noise ratio enhancement for MEMS resonant sensors with potential barrier adjustable stochastic resonance [PDF]

open access: yesMicrosystems & Nanoengineering
The signature of stochastic resonance is that additional noise surprisingly enhances the signal-to-noise ratio (SNR). A noise-adaptive system that learns to add an optimal amount of noise to trigger stochastic resonance and improve SNR is known as ...

Controlled Symmetry with Woods-Saxon Stochastic Resonance Enabled Weak Fault Detection [PDF]

open access: yesSensors, 2023
Weak fault detection with stochastic resonance (SR) is distinct from conventional approaches in that it is a nonlinear optimal signal processing to transfer noise into the signal, resulting in a higher output SNR.

Double Entropic Stochastic Resonance [PDF]

open access: yesEPL (Europhysics Letters), 2009
We demonstrate the appearance of a purely entropic stochastic resonance (ESR) occurring in a geometrically confined system, where the irregular boundaries cause entropic barriers.

Stochastic resonance in MoS2 photodetector [PDF]

open access: yesNature Communications, 2020
Here, the authors take advantage of stochastic resonance in a photodetector based on monolayer MoS2 for measuring otherwise undetectable, ultra-low-intensity, subthreshold optical signals from a distant light emitting diode in the presence of a finite ...

Recent Trends of Controlling Chaotic Resonance and Future Perspectives

open access: yesFrontiers in Applied Mathematics and Statistics, 2021
Stochastic resonance is a phenomenon in which the effects of additive noise strengthen the signal response against weak input signals in non-linear systems with a specific barrier or threshold.

Memory Storage Systems Utilizing Chaotic Attractor-Merging Bifurcation

open access: yesIEEE Access, 2022
In nonlinear dynamical systems with barriers/thresholds, the signal response against a weak external input signal is enhanced by an appropriate additive noise (stochastic resonance).
