Factores de influencia en las actitudes hacia la estadística de alumnos de educación media
(Grupo Editorial Espacios, 2018)No cabe duda de la importancia que tiene la estadística en la formación integral de todos los ciudadanos. A pesar de ello, los resultados de diversas investigaciones señalan que los estudiantes muestran actitudes negativas ... -
Flexible and efficient discretizations of multilayer models with variable density
(Elsevier, 2021)We show that the semi-implicit time discretization approaches previously introduced for multilayer shallow water models for the barotropic case can be also applied to the variable density case with Boussinesq approximation. ... -
Formación del Profesorado en Educación Matemática en España: Producción de Tesis Doctorales y de Artículos
(Junta de Andalucía, Grupo "Didáctica de la Matemática. Pensamiento Numérico", 2007)We present a global perspective of mathematics teachers training in the Spanish educational system. In the case of future primary teachers, mathematics education is part of the content of their higher education, although ... -
Formal deduction of the Saint-Venant-Exner model including arbitrarily sloping sediment beds and associated energy
(2017-04-04)In this work we present a deduction of the Saint-Venant-Exner model through an asymptotic analysis of the Navier-Stokes equations. A multi-scale analysis is performed in order to take into account that the velocity of ... -
El foro en la plataforma Moodle: un recurso de la participación cooperativa para al aprendizaje de las matemáticas
(Universidad de Córdoba, 2012)Presentamos un avance de los resultados de una investigación sobre el uso de la plataforma Moodle en asignaturas de matemáticas. Se analiza el uso y la participación de los estudiantes de un primer curso de universidad a ... -
From (Secure) w-Domination in Graphs to Protection of Lexicographic Product Graphs
(Springer, 2021)Let w = (w0,w1, . . . ,wl) be a vector of nonnegative integers such that w0 ≥ 1. Let G be a graph and N(v) the open neighbourhood of v ∈ V(G). We say that a function f : V(G) −→{0,1, . . . , l} is a w-dominating function ... -

Galilean Generalized Robertson-Walker spacetimes: a new family of Galilean geometrical models
(American Institute of Physics, 2018)We introduce a new family of Galilean spacetimes, the Galilean generalized Robertson-Walker spacetimes. This new family is relevant in the context of a generalized Newton-Cartan theory. We study its geometrical structure ... -
Generalization in interactive groups. An experience within a functional context in early algebra
(ICME, 2024)In this study, we analyze the generalization process carried out by 9- and 10-year-old students working on two linear function tasks in interactive groups (IG). Among the findings, we observe that students show different ... -
Geometría Selecta Theorica, y Práctica del matemático cordobés Gonzalo Antonio Serrano
(UCOPress, 2018)Gonzalo Antonio Serrano fue un médico, matemático y astrónomo cordobés del siglo XVIII con un gran volumen de publicaciones en diversas áreas científicas. En este artículo realizamos un análisis contenido de una de sus ... -
Global existence for Schrödinger-Debye system for initial data with infinite L2 - norm
(American Mathematical Society - AMS, 2015)In this paper we study global-in-time existence for the Cauchy problem associated to the Schrödinger-Debye system for a class of initial data with infinite L^2-norm, namely weak-L^p spaces. This model appears in nonlinear ... -
Global well-posedness for a coupled modified Korteweg-de Vries system
(Springer, 2012)We prove the sharp global well-posedness result for the initial value problem (IVP) associated to the system of the modified Korteweg-de Vries (mKdV) equation. For the singlemKdV equation such result has been obtained by ... -
Grado de molienda y utilización del alimento por conejos en crecimiento. I. Efecto del uso de tamices de 3 y 8 mm de diámetro
(Universidad de Córdoba, Servicio de Publicaciones, 1989)Four grinding procedures of the same diet were used to test the effect of grinding on food utilization for growing rabbits. The dietary ingredients (alfalfa hay: 480.0, barley grain: 189.0, wheat bran: 188.0, soybean meal: ... -
IFCP Riemann solver: Application to tsunami modelling using GPUs
(2017-01-18)In this work, we present a simplified two-layer model of Savage-Hutter type to simulate tsunamis generated by landslides (see (Fern´andez et al. 2008)). A layer composed of fluidized granular material is assumed to flow ... -
Ill-posedness for the Benney system
(AIMS-American Institute of Mathematical Sciences, 2006)We discuss ill-posedness issues for the initial value problem associated to the Benney system. To prove our results we use the method introduced by Kenig, Ponce and Vega to show ill-posedness for some canonical dispersive ... -

Infinitesimal relative position vector fields for observers in a reference frame and applications to conformally stationary spacetimes
(Springer, 2019)We introduce and analyze the concept of infinitesimal relative position vector field between “infinitesimally nearby” observers, showing the equivalence between different definitions. Through the Fermi–Walker derivative ...
