Adjusting fuzzy automata for string similarity measuring
(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 ...
Formulas for the amplitude of the van der Pol limit cycle through the homotopy analysis method
(Hindawi / Wiley, 2009)
info:eu-repo/semantics/article,
The limit cycle of the van der Pol oscillator, x¨+ε(x2−1)x˙+x=0, is studied in the plane (x,x˙) by applying the homotopy analysis method. A recursive set of formulas that approximate the amplitude and form of this limit ...
Hill problem analytical theory to the order four: application to the computation of frozen orbits around planetary satellites
(Hindawi Publishing Corporation, 2009)
Artículo / Artikulua,
Frozen orbits of the Hill problem are determined in the double-averaged problem, where short and long-period terms are removed by means of Lie transforms. Due to the perturbation method we use, the initial conditions ...
A combined fractional step domain decomposition method for the numerical integration of parabolic problems
(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
(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 ...
A mixed-FEM and BEM coupling for the approximation of the scattering of thermal waves in locally non-homogeneous media
(EDP Sciences, 2006)
info:eu-repo/semantics/article,
This paper proposes and analyzes a BEM-FEM scheme to approximate a time-harmonic
diffusion problem in the plane with non-constant coefficients in a bounded area. The model is set as
a Helmholtz transmission problem with ...
Aprender matemáticas con el ordenador
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2004)
Libro / Liburua,
Los futuros perfiles profesionales de nuestros actuales alumnos universitarios están cambiando vertiginosamente. Uno de los grandes cambios es el que viene dado por la incorporación del ordenador a la mayoría (casi todos) ...
Convergent asymptotic expansions of Charlier, Laguerre and Jacobi polynomials
(Cambridge University Press, 2004)
info:eu-repo/semantics/article,
Convergent expansions are derived for three types of orthogonal polynomials:
Charlier, Laguerre and Jacobi. The expansions have asymptotic properties for large
values of the degree. The expansions are given in terms of ...
Parallel solution of nonlinear parabolic problems on logically rectangular grids
(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 ...
