Delaunay solutions to the Cahn-Hilliard equations
(Universidad de Chile, 2017)
En esta tesis doctoral se construyen soluciones rotacionalmente simétricas de la ecuación de Cahn-Hilliard en $ \R{^d} $ y se estudian sus propiedades de estabilidad.
En el Capítulo \ref{ch1} se presenta la ecuación de ...
Optimal control in a noisy system
(AMER INST PHYSICS, 2008-07-21)
We describe a simple method to control a known unstable periodic orbit UPO in the presence of
noise. The strategy is based on regarding the control method as an optimization problem, which
allows us to calculate a ...
Design of fuzzy robust control strategies for a distributed solar collector field
(Elsevier Ltd, 2018)
This paper presents novel control strategies using Takagi–Sugeno fuzzy models combined with a parametric uncertainty robust control approach to address both the nonlinearities of a process and the disturbances that act on ...
Attitude stability of artificial satellites subject to gravity gradient torque
(Springer, 2009-08-01)
The stability of the rotational motion of artificial satellites is analyzed considering perturbations due to the gravity gradient torque, using a canonical formulation, and Andoyer's variables to describe the rotational ...
Densidade de Estados para o Modelo de Anderson Discreto
(Universidade Estadual Paulista (UNESP), 2019-02-22)
O presente trabalho tem como objetivo principal estudar a densidade de estados para o modelo de Anderson discreto multidimensional. Tal modelo constitui uma família de operadores de Schrödinger aleatórios e ergódicos. ...
