A Hartman-Nagumo type condition for a class of contractible domains
(Juliusz Schauder Ctr Nonlinear Studies, 2013-06)
We generalize an existence result on second order systems with a nonlinear term satisfying the so-called Hartman-Nagumo condition. The generalization is based on the use of Gauss second fundamental form and continuation ...
O problema de Dirichlet para a equacão dos gráficos mínimos com dado no bordo lipschitz contínuo
(Universidade Federal de Santa MariaBrasilMatemáticaUFSMPrograma de Pós-Graduação em MatemáticaCentro de Ciências Naturais e Exatas, 2016-12-02)
In this work, we study existence and non existence for the Dirichlet problem for the minimal
graph equation in non convex domains of the plane. We search for conditions on the boundary
data which be the less restricted ...
Remarks on lipschitz solutions to measurable differential inclusions and an existence result for some nonconvex variational problems
(HELDERMANN VERLAG, 2008)
In this paper we examine the problem of finding a Lipschitz function on an open domain with prescribed boundary values and whose gradient is required to satisfy some nonhomogeneous pointwise constraints a.e. in the domain. ...
Design of reactor-separator-recycle systems based on the optimization of estimations of the domain of attraction
(American Chemical Society, 2011-06)
In this paper, an optimization-based methodology is applied to the design of a reactor-separator-recycle system based on a measure of the extension of the domain of attraction of the operating equilibrium. The approach ...
Variational limits of problems in junction domains for ferroelectric and hyperelastic materials by reduction of dimensión = Problemas límites en la modelización de fenómenos ferro-eléctricos e hiperelásticos en la unión de dominios por reducción de dimensión.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Matemática., 2020)
In this work, firstly we study the junction phenomena for two joined thin structures in two kind of context, the
first: ferroelectricity, starting from a non-convex and nonlocal 3D-variational model for the electric ...
A note on the local approximation properties of piecewise polynomials with applications to LDG methods
(2006)
In this article we generalize some standard local approximation properties of piecewise polynomials, which are measured only in the Sobolev seminorms of order 0 and 1, to the case of fractional Sobolev seminorms. The ...
Controle preditivo iterativo não linear multivariável sob restrições com complexidade temporal reduzida
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E DE COMPUTAÇÃO, 2018-05-25)
This thesis deals with the numerical resolution of optimal control problems using an
iterative Model Predictive Control (MPC) method for non-linear multivariable systems
under constraints. This iterative method was ...
Operational management of crude oil supply: models and solution strategies
(2020)
Esta tese de doutorado avança o estado da arte do gerenciamento de suprimento de óleo cru propondo modelos de programação matemática e algoritmos que tratam deste problema de forma integrada no nível de decisão operacional. ...
Vortex Search Algorithm for Optimal Sizing of Distributed Generators in AC Distribution Networks with Radial Topology
(Springer, 2019)
This paper proposes a vortex search algorithm (VSA) optimization for optimal dimensioning of distributed generators (DGs), in radial alternating current (AC) distribution networks. The VSA corresponds to a metaheuristic ...
