Metastability for small random perturbations of a PDE with blow-up
(Elsevier Science, 2018-05)
We study random perturbations of a reaction–diffusion equation with a unique stable equilibrium and solutions that blow-up in finite time. If the strength of the perturbation ε>0 is small and the initial data is in the ...
On the analytical solution for the slewing flexible beam-like system: analysis of the linear part of the perturbed problem
The dynamical system investigated in this work is a nonlinear flexible beam-like structure in slewing motion. Non-dimensional and perturbed governing equations of motion are presented. The analytical solution for the linear ...
Comparison of FACTS STATCOM models for damping oscillations in power system due to small perturbations
This paper presents small-signal stability studies of a multimachine power system, considering Static Synchronous Compensators (STATCOM)and discussed control modes of the STATCOM. The Power Sensitivity Model(PSM)is used ...
Spike-layered Solutions of Singularly Perturbed Elliptic Problems in a Degenerate Setting
In this paper we consider a class of nonlinear singularly perturbed elliptic problems of the form ε2 Δu - u + f(u) = 0 in Ω, for a superlinear, subcritical function f. Here Ω a smooth bounded domain, ε > 0 is a small ...
Random perturbations of stochastic processes with unbounded variable length memory
(UNIV WASHINGTON, DEPT MATHEMATICS, 2008)
We consider binary infinite order stochastic chains perturbed by a random noise. This means that at each time step, the value assumed by the chain can be randomly and independently flipped with a small fixed probability. ...
Stability of the curvature perturbation in dark sectors` mutual interacting models
(ELSEVIER SCIENCE BV, 2009)
We consider perturbations in a cosmological model with a small coupling between dark energy and dark matter. We prove that the stability of the curvature perturbation depends on the type of coupling between dark sectors. ...
