(2005-04-15)The effect of additive noise on a static front that connects a stable homogeneous state with an also stable but spatially periodic state is studied. Numerical simulations show that noise induces front propagation. The ...
-
(2000)We prove that the exact non local equation derived by the present authors for the temporal linear evolution of the surface of a viscous incompressible fluid reduces asymptotically for high viscosity to a second order ...
-
(2000-10-30)We study the dynamics of bubbles in the one dimensional Cahn-Hilliard equation. For a gas of diluted bubbles we find ordinary differential equations describing their interaction which permits us to describe the ulterior ...
-
(2002)We recall our approach through discretizations for path integrals and its general results for representations of probability densities. It is shown that the result of Arnold @P. Arnold, Phys. Rev. E 61, 6099 ~2000!# is ...

(Universidad de Chile, 2007)En este trabajo se analizó la factibilidad de alcanzar los límites de descarga de efluentes impuestos por el DSN°90/200, a través, de la evaluación de alternativas de remoción biológica de nutrientes que permitan cumplir ...
-
(Universidad de Chile, 2015)El objetivo principal de esta tesis fue estudiar el efecto del ruido interno en el límite de baja intensidad sobre patrones y paredes de dominio entre estados simétricos, particularmente analizando como afecta el ruido a ...
-
(Universidad de Chile, 2013)El objetivo de esta tesis fue estudiar y caracterizar los efectos del acomplamiento traslacional y del ruido, sobre estados localizados y soluciones periódicas (o patrones) en sistemas macroscópicos. En el contexto de un ...

(1997-02-03)We derive an exact equation which is nonlocal in time for the linear evolution of the surface of a viscous fluid, and show that this equation becomes local and of second order in an interesting limit. We use our local ...
-
(Universidad de ChilePrograma Cybertesis, 2009)En esta tesis se estudian los frentes y las estructuras localizadas en sistemas conformados por una gran cantidad de pequeños subsistemas idénticos acoplados entre sí, los cuales son descritos en términos de ecuaciones ...
-
(World Scientific Publishing Company, 2009)A short review is given of recent papers on the relaxation to (incompressible) absolute equilibrium. A new algorithm to construct absolute equilibrium of spectrally truncated compressible flows is described. The algorithm ...
-
(Universidad de Chile, 2018)El presente es un estudio del fenómeno de la Inestabilidad de Faraday en una celda de Hele-Shaw especialmente delgada lo que provocó histéresis en el cambio de estado de equilibrio. Este escrito consiste de tres capítulos. ...

(2005)We study numerically a prototype equation which arises generically as an envelope equa- tion for a weakly inverted bifurcation associated to traveling waves: The complex quintic Ginzburg{Landau equation. We show six di ...
-
(1999-11-08)We describe the two generic instabilities which arise in quasireversible systems and show that their normal forms are the well-known real Lorenz equations and the Maxwell-Bloch equations. We present for the first time ...
-
(Royal Society Publishing, 2018)We provide numerical solutions based on the path integral representation of stochastic processes for nongradient drift Langevin forces in the presence of noise, to follow the temporal evolution of the probability density ...
-
(2004)We study analytically a system sustainingstable movinglocalized structures, namely, the one-dimensional quintic complex Ginzburg–Landau (G–L) equation with non-linear gradients. We obtain approximate solutions for the ...
-
(2007)We study the nonlinear robust behaviors of a model for the deposition of a monolayer of molecules on a surface which takes into account the interactions of the adsorbed molecules. The transport properties of the model ...
-
(1994-04-18)The simplest interaction between sound and quantized superfluid vortices is investigated both analytically in the Born approximation and numerically, using the nonlinear Schrodinger equation. Compared with the scattering ...
