Effects of a soft-core coulomb potential on the dynamics of a hydrogen atom near a metal surface
(Elsevier, 2019)
Artículo / Artikulua,
The goal of this paper is to investigate the effects that the replacement of the Coulomb potential by a soft-core Coulomb potential produces in the classical dynamics of a perturbed Rydberg hydrogen atom. As example, we ...
Nested formulation paradigms for induced ordered weighted averaging aggregation for decision‐making and evaluation
(Wiley, 2019)
info:eu-repo/semantics/article,
Existing extensions to Yager's ordered weighted aver-aging (OWA) operators enlarge the application rangeand to encompass more principles and properties relatedto OWA aggregation. However, these extensions do notprovide a ...
Dealing with uncertainty: a human perception approach in image processing
(2019)
info:eu-repo/semantics/doctoralThesis,
Una de las maneras de abordar la comparación entre objetos es mediante el uso de la similitud (comparando sus atributos comunes) o la disimilitud (comparando sus diferencias). La similitud ha sido estudiada de maneras muy ...
Multidisciplinary design of wind turbine blades
(2019)
info:eu-repo/semantics/doctoralThesis,
The impressive growth of the wind energy in the recent years makes necessary to improve the traditional design tools in order to respond to the high competitiveness. One of the most challenging component to be designed is ...
Online relative risks/rates estimation in spatial and spatio-temporal disease mapping
(Elsevier, 2019)
info:eu-repo/semantics/article,
Background and objective: Spatial and spatio-temporal analyses of count data are crucial in epidemiology and other fields to unveil spatial and spatio-temporal patterns of incidence and/or mortality risks. However, fitting ...
Geometric multigrid methods for Darcy–Forchheimer flow in fractured porous media
(Elsevier, 2019)
info:eu-repo/semantics/article,
In this paper, we present a monolithic multigrid method for the efficient solution of flow problems in fractured porous media. Specifically, we consider a mixed-dimensional model which couples Darcy flow in the porous ...
On co-orbital quasi-periodic motion in the three-body problem
(Society for Industrial and Applied Mathematics (SIAM), 2019)
Artículo / Artikulua,
Within the framework of the planar three-body problem we establish the existence of quasi-periodic motions and KAM 4-tori related to the co-orbital motion of two small moons about a large planet where the moons move in ...
Reeb’s theorem and periodic orbits for a rotating Hénon–Heiles potential
(Springer, 2019)
Artículo / Artikulua,
We apply Reeb’s theorem to prove the existence of periodic orbits in the rotating Hénon–
Heiles system. To this end, a sort of detuned normal form is calculated that yields a reduced
system with at most four non degenerate ...
Multiscale edge detection using first-order derivative of anisotropic Gaussian kernels
(Springer, 2019)
info:eu-repo/semantics/article,
Spatially scaled edges are ubiquitous in natural images. To better detect edges with heterogeneous widths, in this paper, we propose a multiscale edge detection method based on first-order derivative of anisotropic Gaussian ...
Simheuristic algorithms for the sustainable freight transport problem
(2019)
info:eu-repo/semantics/doctoralThesis,
The sustainable freight transport entails the design of the distribution plans with the least negative impacts. On one hand, this distribution problem relies on deter-mining the routes to visit a set of customers, which ...
