Stochastic fluid dynamics equations with multiplicative noise [PDF]

, 2022
In the first two chapters, a concise introduction to stochastic integration in Hilbert spaces is given. In the third chapter, a stochastic Leray-alpha model of Euler equations, obtained by adding a Stratonovich multiplicative noise to the ...

Multidimensional Speckle Noise Model

EURASIP Journal on Advances in Signal Processing, 2005
One of the main problems of SAR imagery is the presence of speckle noise, originated by the inherent coherent nature of this type of systems. For one-dimensional SAR systems it has been demonstrated that speckle can be considered as a multiplicative ...

Combinatorial Designs with Two Singular Values I. Uniform Multiplicative Designs [PDF]

In this and a sequel paper [10] we study combinatorial designs whose incidence matrix has two distinct singular values.These generalize 2-(v, k, É) designs, and include partial geometric designs and uniform multiplicative designs.Here we study the latter,

Random Dynamical Systems with Multiplicative Noise [PDF]

The paper considers random economic systems generating nonlinear time series on the positive half-ray R+. Using Liapunov techniques, new conditions for existence, uniqueness and stability of stationary equilibria are obtained.

Approximations in Mean Square Analysis of Stochastically Forced Equilibria for Nonlinear Dynamical Systems

Mathematics
Motivated by important applications to the analysis of complex noise-induced phenomena, we consider a problem of the constructive description of randomly forced equilibria for nonlinear systems with multiplicative noise.

Estimation of influence of correlated non-Gaussian noise on measuring accuracy of signal information parameters

Физика волновых процессов и радиотехнические системы, 2018
The potential measuring accuracy of the signal information parameters on background of non-Gaussian correlated additive and multiplicative noise in short range conditions is estimated.

Exploring the interaction between ambient air pollution and road traffic noise on stroke incidence in ten Nordic cohorts

Environment International
Introduction: Ambient air pollution and road traffic noise are stroke risk factors, but evidence on their potential joint effects remains limited. This study investigated the independent and joint associations of air pollution and road traffic noise on ...

Capturing the Zero: A New Class of Zero-Augmented Distributions and Multiplicative Error Processes [PDF]

We propose a novel approach to model serially dependent positive-valued variables which realize a non-trivial proportion of zero outcomes. This is a typical phenomenon in financial time series observed on high frequencies, such as cumulated trading ...

Suprathreshold stochastic resonance mediated by multiplicative noise

We have investigated information transmission in an array of threshold units. Each unit receives a common input signal but independent multiplicative noise.
