Análisis de Estabilidad de un Controlador PID WAVELET
(2011)En este trabajo se analiza la estabilidad de un controlador PID multiresolución, el cual hace uso de la teorÃa wavelet para la descomposición de la señal de error de seguimiento. Se presenta una función de error general ... -
Attentional deficits in concussion
(2005)Primary objective: The purpose of the present study was to examine deficits in the alerting, orienting and executive components of attention in individuals who have recently suffered a concussion. Research design: A group ... -
Bloch Floquet waves and localisation within a heterogeneous waveguide with long cracks
(2010)A bi-material waveguide is assumed to have an array of sufficiently long cracks parallel to the boundaries. The BlochÂFloquet waves propagating along such a waveguide are dispersive, and the band gaps are clearly identified. ... -
Cognitive Decline An Analysis of the Elderly Population in Isolated Regions of Mexico
(2014)Worldwide studies in the last decade have measured the rate of cognitive decline in the elderly population, mainly in Australia, Europe, United States, and Canada. In Mexico, this information is very limited and the ... -
Un enfoque histórico y epistemológico de la noción de linealidad
(2010)Se presenta un estudio histórico y epistemológico acerca de la noción de linealidad, donde se muestran aspectos relevantes sobre su génesis y desarrollo, haciendo un rescate de la misma, hasta mostrar su aparición en ... -
Estudio experimental de la viscosidad de un fluido magneto-reológico a base de magnetita mineral
(2007)Estudiamos experimentalmente la viscosidad de un fluido magneto-reológico (MR) a base de magnetita mineral y aceite automotriz parafrenos. Usamos un reómetro Brookfield de geometrÃa cono-plato al cual se le adapt´o un ... -
Math Processing Interferes with Directing Attention into the Right Visual Field
(2002)A supplement of the Journal of Cognitive Neuroscience 2002. -
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 ... -
LA RESIGNIFICACIÓN DE LA NOCIÓN DE LINEALIDAD
(2008)Se considera que la noción de linealidad toma distintos significados, por los dominios matemáticos por losque transita en el currÃculo escolar. Está vinculada desde una perspectiva epistemológica a la noción ... -
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 ...
