Analysis of a coupled fluid-structure model with applications to hemodynamics
(Society for Industrial and Applied Mathematics, 2016)
We propose and analyze a simplified fluid-structure coupled model for flows with compliant walls. As in [F. Nobile and C. Vergara, SIAM J. Sci. Comput., 30 (2008), pp. 731-763], the wall reaction to the fluid is modeled ...

Enhancing robustness and sparsity via mathematical optimization
(2016-09-22)
Esta tesis se centra en derivar métodos robustos o dispersos bajo la perspectiva de la optimización para problemas que tradicionalmente se engloban en los campos de la Estadística o de la Investigación Operativa. Concretamente, ...

Optimization models in solar power tower plant design. Design of the heliostat field and the tower receivers
(2016-01-08)
El diseño de plantas solares con tecnología de torre (utilizaremos las siglas en inglés SPT) comenzó a ser estudiado en los años 70 y sigue siendo hoy en día un área de investigación muy activa. En esta tesis doctoral se ...

Rank aggregation in cyclic sequences
(Springer, 2016-05-10)
In this paper we propose the problem of finding the cyclic sequence which best represents a set of cyclic sequences. Given a set of elements and a precedence cost matrix we look for the cyclic sequence of the elements which ...

On the Muskat problem: global in time results in 2D and 3D
(Johns Hopkins University Press, 2016-12)
This paper considers the three dimensional Muskat problem in the stable regime. We obtain a conservation law which provides an L2 maximum principle for the fluid interface. We also show global in time existence for strong ...

On Extreme Concentrations in Chemical Reaction Networks with Incomplete Measurements
(ACS, 2016-11-09)
A fundamental problem in the analysis of chemical reactions networks consists of identifying concentration values along time or in steady state which are coherent with the experimental concentration data available. When ...

On the stability of approximations for the Stokes problem using different finite element spaces for each component of the velocity
(Elsevier, 2016-01)
This paper studies the stability of velocity-pressure mixed approximations of the Stokes problem when different finite element (FE) spaces for each component of the velocity field are considered. We consider some new ...

Derived homotopy algebras
(2016-10-28)
Derived A-algebras are derived and homotopy invariant versions of differential graded algebras. They were introduced by Steffen Sagave in 20 0 in order to construct minimal models for diferential graded algebras over ...

Analysis of a full space-time discretization of the Navier-Stokes equations by a local projection stabilization method
(Oxford University Press, 2016)
A finite element error analysis of a local projection stabilization (LPS) method for the time-dependent Navier–Stokes equations is presented. The focus is on the high-order term-by-term stabilization method that has one ...
