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 ...
Some nonlocal optimal design problems
(Academic Press Inc Elsevier Science, 2018-03)
In this paper we study two optimal design problems associated to fractional Sobolev spaces Ws,p(Ω). Then we find a relationship between these two problems and finally we investigate the convergence when s↑1.
Optimal bundles in normed spaces
(Duke University Press, 2013)
In this paper, we prove existence of optimal bundles for a countable set of data in a broad class of normed spaces, which extend previous known results for a finite data set in a Hilbert space. In addition, we study the ...
Remarks on an optimization problem for the p-Laplacian
(Pergamon-Elsevier Science Ltd, 2010-02)
In this note we give some remarks and improvements on a recent paper of us [3] about an optimization problem for the p−Laplace operator that were motivated by some discussion the authors had with Prof. Cianchi.
Optimization of polytomies: State set and parallel operations
(Academic Press Inc Elsevier Science, 2002-02)
New algorithms for calculating the most parsimonious state sets for polytomies under Fitch parsimony are described. Because they are based on state set operations, these algorithms can be extended for optimization of several ...
CO-PrOx reactor design by model-based optimization
(Elsevier Science, 2008-07)
This work analyzes the CO-PrOx reactor design as a component of the CO clean-up system of the ethanol processor for H2 production applied to PEM fuel cells. The operating conditions of the processor require compact and ...
Convergence Results for Optimal Control Problems Governed by Elliptic Quasivariational Inequalities
(Taylor & Francis, 2020-08)
We consider an optimal control problem (Formula presented.) governed by an elliptic quasivariational inequality with unilateral constraints. We associate to (Formula presented.) a new optimal control problem (Formula ...
Time-optimal control fields for quantum systems with multiple avoided crossings
(American Physical Society, 2015-10)
We study time-optimal protocols for controlling quantum systems which show several avoided level crossings in their energy spectrum. The structure of the spectrum allows us to generate a robust guess which is time-optimal ...
Multi-stage optimal control of lignocellulosic bioethanol production
(Planta Piloto de Ingeniería Química, 2020-05)
The dynamics of production and purification of ethanol from sorghum lignocellulosic materials by a three stages process was modeled and optimized in this work. The process involves a first stage for hydrolyzing sweet sorghum ...
