PROPAGATION OF ELASTIC WAVES ALONG INTERFACES IN LAYERED BEAMS
(2004)An asymptotic model is proposed for the analysis of a long-wave dynamic model for a layered structure with an imperfect interface. Two layers of isotropic material are connected by a thin and soft adhesive: effectively the ... -
LA RESIGNIFICACIÓN DE LA NOCIÓN DE LINEALIDAD
(2010)Se considera que la noción de linealidad toma distintos significados, por los dominios matemáticos por los que transita en el currÃculo escolar. Está vinculada desde una perspectiva epistemológica a la noción de ... -

Slow decay of end effects in layered structures with an imperfect interface
(2003)An asymptotic analysis of a layered structure with an imperfect interface subject to an anti-plane shear deformation and non-homogeneous Dirichlet end conditions is presented in this paper. Two layers of isotropic materials ... -
TEACHERS' CONSTRUCTION OF DYNAMIC MATHEMATICAL MODELS BASED ON THE USE OF COMPUTATIONAL TOOLS
(2009)To what extent does the use of computational tools offer teachers the possibility of constructing dynamic models to identify and explore diverse mathematical relations? What ways of reasoning or thinking about the problems ... -
Three-dimensional structures of RNA obtained by means of knowledge-based interaction potentials.
(2010)We derive a set of effective potentials describing the interaction between pairs of nucleotides that belong to an RNA molecule. Such interaction potentials are then used as the main constituents of a simplified simulation ... -
Tracking the recovery of visuospatial attention deficits in mild traumatic brain injury
(2006)The goal of the current investigation was to probe the deficits in the alerting, orienting and executive components of visuospatial attention in individuals who have recently suffered a mild traumatic brain injury (mTBI) ... -
WAYS OF REASONING AND TYPES OF PROOFS THAT MATHEMATICS TEACHERS SHOW IN TECHNOLOGY-ENHANCED INSTRUCTION
(2006)In this report we document and analyze the ways of reasoning and types of proofs employed by high school mathematics teachers to validate conjectures and to justify procedures in order to solve problems, which emerge when ...
