Fast transport asymptotics for stochastic RDEs with boundary noise
Multiscaling limits for stochastic reaction-diffusion equations
2011/2/21
We consider a class of stochastic reaction-diffusion equations also having a stochastic perturbation on the boundary and we show that when the diffusion rate is much larger than the rate of reaction, ...
Universal Communication over Modulo-additive Channels with an Individual Noise Sequence
Universal Communication Modulo-additive Channels Individual Noise Sequence
2011/1/21
Which communication rates can be attained over an unknown channel where the relation between the input and output can be arbitrary? A channel where the output is any arbitrary (possibly stochastic) fu...
Spectrum is the most valuable resource in the communication system, but unfor-tunately, so far, a half of the spectrum has been wasted, that is negative frequency spectrum.

Generalized Methods and Solvers for Noise Removal from Piecewise Constant Signals
Generalized Methods Solvers Noise Removal
2011/1/4
Removing noise from piecewise constant (PWC) signals, is a challenging signal processing problem arising in many practical contexts. For example, in exploration geosciences, noisy drill hole records n...

stochastic age-dependent population equations compensated Poisson random measure
2010/9/25
It presents and analyzes the Euler methods for stochastic age-dependent population equations driven by Poisson random jump measure; Under the Local Lipschitz condition, we prove that the Euler approxi...

Black-Scholes equation white noise kernel
2010/9/25
In this paper, we study the well known equation which is the Black-Scholes equation in the form of white noise. We found the kernel of such equation and obtained some interesting properties of such ke...
Low noise limit for the invariant measure of a multi-dimensional stochastic Allen-Cahn equation
Stochastic reaction-di usion equation Invariant measure Large deviations
2011/1/21
We study the invariant measure of a discretized stochastic Allen-Cahn equation in d+1 dimensions in the low noise limit. We consider a cuboidal domain and impose the two stable
phases as boundary con...

We construct solutions to Burgers type equations perturbed by a multiplicative spacetime white noise in one space dimension.
Sensitivity to noise and ergodicity of an assembly line of cellular automata that classifies density
Statistical Mechanics (cond-mat.stat-mech) Disordered Systems and Neural Networks (cond-mat.dis-nn) Cellular Automata and Lattice Gases (nlin.CG)
2010/11/10
We investigate the sensitivity of the composite cellular automaton of H. Fuk\'{s} (Phys. Rev. E 55, R2081 (1997)) to noise and assess the density classification performance of the resulting probabilis...
Kernel random matrices have attracted a lot of interest in recent years, from both practical and theoretical standpoints. Most of the theoretical work so far has focused on the case were the data is s...
