Multidomain Chebyshev pseudo-spectral method applied to the Poisson–Boltzmann equation for two parallel plates
Autor: Leonardo S. Borges, Luciano Bedin, Fermín S. V. Bazán
Publikováno v: Journal of Engineering Mathematics. 127
We address a boundary-value problem involving a Poisson–Boltzmann equation that models the electrostatic potential of a channel formed by parallel plates with an electrolyte solution confined between the plates. We show the existence and uniqueness

Estimation of the local heat-transfer coefficient in the laminar flow regime in coiled tubes by the Tikhonov regularisation method
Autor: Sara Rainieri, Fermín S. V. Bazán, Luca Cattani, Fabio Bozzoli, Leonardo S. Borges
Publikováno v: International Journal of Heat and Mass Transfer. 72:352-361
Wall curvature is a widely used technique to passively enhance convective heat transfer that has proven to also be effective in the thermal processing of highly viscous fluids. These geometries produce a highly uneven convective heat-flux distributio

Extension of GKB-FP algorithm to large-scale general-form Tikhonov regularization
Autor: Leonardo S. Borges, Fermín S. V. Bazán, Maria Cristina de Castro Cunha
Publikováno v: Numerical Linear Algebra with Applications. 21:316-339
SUMMARY In a recent paper an algorithm for large-scale Tikhonov regularization in standard form called GKB-FP was proposed and numerically illustrated. In this paper, further insight into the convergence properties of this method is provided, and ext

On a generalization of Regińska’s parameter choice rule and its numerical realization in large-scale multi-parameter Tikhonov regularization
Autor: Fermín S. V. Bazán, Juliano B. Francisco, Leonardo S. Borges
Publikováno v: Applied Mathematics and Computation. 219:2100-2113
A crucial problem concerning Tikhonov regularization is the proper choice of the regularization parameter. This paper deals with a generalization of a parameter choice rule due to Reginska (1996) [31] , analyzed and algorithmically realized through a

GKB-FP: an algorithm for large-scale discrete ill-posed problems
Autor: Leonardo S. Borges, Fermín S. V. Bazán
Publikováno v: BIT Numerical Mathematics. 50:481-507
We describe an algorithm for large-scale discrete ill-posed problems, called GKB-FP, which combines the Golub-Kahan bidiagonalization algorithm with Tikhonov regularization in the generated Krylov subspace, with the regularization parameter for the p
