Stabilization by Noise Revisited

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1990
AbstractGiven a d × d matrix A and a d × k matrix B. We investigate how the stability behavior of ẋ = (A + BG(t)) × can be improved by a k × d matrix‐valued white noise process G(t). The analysis is based on the theory of Lyapunov exponents (exponential growth rates) and uses an averaging principle.

On the stability of the basis pursuit in the presence of noise

Signal Processing, 2006
Given a signal S ∈ RN and a full-rank matrix D ∈ RN × L with N < L, we define the signal's overcomplete representation as α ∈ RL satisfying S= Dα. Among the infinitely many solutions of this under-determined linear system of equations, we have special interest in the sparsest representation, i.e., the one minimizing ||α||0.

Noise Enhanced Stability in an Unstable System

Physical Review Letters, 1996
We experimentally detect noise enhanced stability in an unstable physical system. The average escape time from a metastable, periodically driven, system is measured in the stable and unstable regimes in a noisy environment. In the unstable regime, we measure that the average escape time has a maximum for a finite value of the noise intensity.

On Stability of Linear Estimators in Poisson Noise

2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019
This paper considers estimation of a random variable in Poisson noise. Specifically, the main focus is to assess optimality and near optimality conditions for linear estimators.In the first part of the paper, it is shown that linear estimators are optimal if and only if the underlying prior is a gamma distribution and the dark current parameter is zero.

Stability of the Tree of Shapes to Additive Noise

2021
The tree of shapes (ToS) is a famous self-dual hierarchical structure in mathematical morphology, which represents the inclusion relationship of the shapes (\textiti.e. the interior of the level lines with holes filled) in a grayscale image. The ToS has already found numerous applications in image processing tasks, such as grain filtering, contour ...

Stability and stabilization of stochastic systems with multiplicative noise

International Journal of Control, Automation and Systems, 2011
In this paper, stability and stabilization of linear stochastic time-invariant systems are studied based on spectrum technique. Firstly, the relationship among mean square exponential stability, asymptotical mean square stability, second-order moment exponential stability and the spectral location of the systems is revealed with the help of a spectrum ...

Stabilization of a nonlinear system by multiplicative noise

Physical Review A, 1991
The effect of multiplicative colored noise on the stabilization of a bistable system is studied numerically. In particular, numerical simulation of a much discussed theoretical study carried out by Graham and Schenzle [Phys. Rev. A 26, 1676 (1982)] is presented.

Stability and stabilization of discrete systems with multiplicative noise

1997 European Control Conference (ECC), 1997
In this paper we consider the problem of the stabilization of unstable stochastic difference systems by the addition of multiplicative noise. We illustrate the possibilities of stabilization by uniformly and normally distributed multiplicative noises. Then we present different approaches to the problem of finding sufficient conditions for stability and
