On stabilization of partial differential equations by noise [PDF]
Nagoya Mathematical Journal, 2001 Some results on stabilization of (deterministic and stochastic) partial differential equations are established. In particular, some stability criteria from Chow [4] and Haussmann [6] are improved and subsequently applied to certain situations, on which the original criteria commonly do not work, to ensure almost sure exponential stability.

Trailing-edge noise reduction of a wing by a surface modification
, 2021 There is an increased emphasis on reducing airframe noise in the last decades. Airframe noise is sound generated by the interaction of a turbulent flow with the aircraft geometry, and significantly contributes to the overall noise production during the ...

Noise-induced stabilization of collective dynamics [PDF]
Physical Review E, 2017 We illustrate a counter-intuitive effect of an additive stochastic force, which acts independently on each element of an ensemble of globally coupled oscillators. We show numerically and semi-analytically that a very small white noise is able to stabilize an otherwise linearly unstable collective periodic regime.

Noise stability and correlation with half spaces
Electronic Journal of Probability, 2018 Benjamini, Kalai and Schramm showed that a monotone function $f : \{-1,1\}^n \to \{-1,1\}$ is noise stable if and only if it is correlated with a half-space (a set of the form $\{x: \langle x, a\rangle \le b\}$). We study noise stability in terms of correlation with half-spaces for general (not necessarily monotone) functions.

Compression by Noise Equalization [PDF]
, 2013 For any relation of the noise variance with the gray value, a nonlinear transform h(g) can be applied so that the variance of the transformed signal h is constant.

Applied Sciences, 2018 This paper investigates the stability problem of the feedback active noise control (ANC) system, which can be caused by the modeling error of the electro-acoustic path estimation in its feedback mechanism.

Laboratory Test of a Vehicle Active Noise-Control System Based on an Adaptive Step Size Algorithm
Applied Sciences, 2022 NVH (noise, vibration, and harshness) is a key factor affecting vehicle comfort. Compared with traditional sound absorption and isolation methods, active noise control (ANC) offers a significant advantage in solving the problem of low- and medium ...

Cyclin G and the Polycomb Repressive complexes PRC1 and PR-DUB cooperate for developmental stability. [PDF]
PLoS Genetics, 2018 In Drosophila, ubiquitous expression of a short Cyclin G isoform generates extreme developmental noise estimated by fluctuating asymmetry (FA), providing a model to tackle developmental stability.

Some remarks on stabilization by additive noise [PDF]
, 2008 We review some results on stabilization of solutions to semilinear parabolic PDEs near a change of stability due to additive degenerate noise. Our analysis is based on the rigorous derivation of a stochastic amplitude equation for the dominant mode and on careful estimates on its solution.
