Contributions to derivative-free optimization: an exact penalty method and decompositions for distributed control
(2019)
Esta tese estende métodos de decomposição para problemas estáticos e controle de sistemas dinâmicos. Um método de penalidade l_1 é proposto para otimização de propósito geral em que não se tem acesso à derivada da função ...
Derivative-free low order-value optimization = : otimização de menor valor ordenado sem derivadas
(Programa de Pós-Graduação em MatemáticaCentro de Ciências Exatas, 2023)
Material design of elastic structures using Voronoi cells
(John Wiley & Sons Ltd, 2018-07)
New tools for the design of metamaterials with periodic microarchitectures are presented. Initially, a two-scale material design approach is adopted. At the structure scale, the material effective properties and their ...
Structural shape optimization by IGABEM and particle swarm optimization algorithm
(Elsevier, 2018)
In this paper, a new approach is developed for structural shape optimization, which consists in coupling the particle swarm optimization (PSO) algorithm and the isogeometric boundary element method (IGA-BEM). The IGA-BEM ...
Bottom detection through surface measurements on water waves
(SIAM publications, 2017)
The direct problem of water-wave equations is the problem of determining the surface and its velocity potential, in time T > 0, for a given initial profile and velocity potential, where the profile of the bottom, the ...
Estudo de algoritmos para o problema de otimização de vazão de poços de petróleo
(Universidade Federal do Espírito SantoBRCiência da ComputaçãoPrograma de Pós-Graduação em InformáticaUFES, 2011-12-21)
Petroleum Engineer activity is constantly enrolled on a series of optimization problems on many contexts, as, for instance, defining efficient and optimized projects on petroleum reserves development. However, there is an ...
