Parallel solution of nonlinear parabolic problems on logically rectangular grids
Arrarás Ventura, Andrés
; Portero Egea, Laura ; Jorge Ulecia, Juan Carlos (Springer, 2007)
Contribución a congreso / Biltzarrerako ekarpena 
This work deals with the efficient numerical solution of nonlinear transient flow problems posed on two-dimensional porous media of general geometry. We first consider a spatial semidiscretization of such problems by ... -
A combined fractional step domain decomposition method for the numerical integration of parabolic problems
Portero Egea, Laura ; Bujanda Cirauqui, Blanca ; Jorge Ulecia, Juan Carlos (Springer, 2004)
Contribución a congreso / Biltzarrerako ekarpena
In this paper we develop parallel numerical algorithms to solve linear time dependent coefficient parabolic problems. Such methods are obtained by means of two consecutive discretization procedures. Firstly, we realize ... -
Embedded pairs of fractional step Runge-Kutta methods and improved domain decomposition techniques for parabolic problems
Portero Egea, Laura ; Jorge Ulecia, Juan Carlos (Springer, 2007)
Contribución a congreso / Biltzarrerako ekarpena
In this paper we design and apply new embedded pairs of Frac- tional Step Runge-Kutta methods to the e±cient solution of multidimensional parabolic problems. These time integrators are combined with a suitable split- ting ... -
Charge transfer in the Rydberg hydrogen atom metal surface interaction: a transition state approach
Salas, José Pablo; Iñarrea, Manuel; Lanchares, Víctor; Palacián Subiela, Jesús Francisco ; Pascual, Ana Isabel; Yanguas Sayas, Patricia (2007)
Contribución a congreso / Biltzarrerako ekarpena
We study the classical dynamics of a hydrogen atom near a metallic surface in the presence of a uniform electric field. By continuation of families of periodic orbits and surfaces of section we show that, due to the electric ... -

On the modeling of the concept: “The Contents of the Empty Set" using the activity orderings family (⊑w)w∈L in a distributive lattice ( L, ≤ ). An interpretation of those order relations ⊑w as alternative inclusions (“w-Inclusions") and of its associated inf- operators ⨅w as additional intersections (“w-Intersections”), both in the Intuitive set theory and in the L-fuzzy set theory. (In Spanish)
Fuentes González, Ramón (2018)

A mathematical model is presented to define new inclusions, intersections and unions as alternatives to the usual ones between crisp and fuzzy subsets. In particular, the concept of “the non-trivial content of the empty ... -
Characterization of radio propagation channel in urban vehicle to infrastructure environments to support WSNs
Granda, Fausto; Azpilicueta Fernández de las Heras, Leyre ; Vargas Rosales, César; López Iturri, Peio ; Aguirre Gallego, Erik ; Astrain Escola, José Javier ; Villadangos Alonso, Jesús ; Falcone Lanas, Francisco Javier (MDPI, 2016)
Contribución a congreso / Biltzarrerako ekarpena
Vehicular ad hoc Networks (VANETs) enable vehicles to communicate with each other as well as with roadside units (RSUs). Although there is a significant research effort in radio channel modelling focused in vehicle to ... -

During the last years, the application of different wireless technologies has been explored in order to enable Internet connectivity from vehicles. In addition, the widespread adoption of smartphones by citizens represents ... -
Adjusting fuzzy automata for string similarity measuring
Astrain Escola, José Javier ; Villadangos Alonso, Jesús ; González de Mendívil Moreno, José Ramón ; Garitagoitia Padrones, José Ramón ; Fariña Figueredo, Federico (EUSFLAT, 2001)
Contribución a congreso / Biltzarrerako ekarpena
In this paper, we introduce a fuzzy automaton for computing the similarity between pairs of strings and a genetic method for adjusting its parameters. The fuzzy automaton models the edit operations needed to transform ... -
