20 p, 954.1 KB Las trayectorias hipotéticas de aprendizaje : Un ejemplo en un curso de álgebra lineal / Cárcamo, Andrea (Universidad Austral de Chile) ; Fortuny, Josep M.. (Josep Maria) (Universitat Autònoma de Barcelona) ; Fuentealba, Claudio (Universidad Austral de Chile)
Este trabajo propone y evalúa una trayectoria hipotética de aprendizaje (THA) para los conceptos de conjunto generador y espacio generado. La THA se diseñó siguiendo el planteamiento de Simon (1995), la heurística de diseño de los modelos emergentes y el mecanismo de reflexión sobre la relación actividad-efecto. [...]
This article proposes and evaluates a hypothetical learning trajectory (HLT) for the concepts of span and spanning set. This HLT was designed following the approach of Simon (1995), the design heuristics of emergent models and the mechanism of reflection on activity-effect relationship. [...]

4 p, 252.9 KB Memory and nonlocal effects in heat transport : from diffusive to ballistic regimes / Àlvarez Calafell, Francesc Xavier (Universitat Autònoma de Barcelona. Departament de Física) ; Jou i Mirabent, David, 1953- (Universitat Autònoma de Barcelona. Departament de Física) ; American Physical Society
The authors discuss a generalized transportmodel including memory and nonlocal effects, which aims to describe the transition of heat transport from the diffusive regime to the ballistic regime. By using an effective thermal conductivity depending on the Knudsen number, they describe in a single equation the behavior of conductivity in terms of the system size and a reduction in the limit flux through nanoscale devices.

9 p, 281.1 KB Trajectory Analysis for Sport and Video Surveillance / Meneses, Y. L. de (Ecole Polytechnique Fédérale de Lausanne. Laboratoire de Production Microtechnique) ; Roduit, P. (Ecole Polytechnique Fédérale de Lausanne. Laboratoire de Production Microtechnique) ; Luisier, F. (Ecole Polytechnique Fédérale de Lausanne. Swarm-Intelligent System Group) ; Jacot, J. (Ecole Polytechnique Fédérale de Lausanne. Swarm-Intelligent System Group)
In video surveillance and sports analysis applications, object trajectories offer the possibility of extracting rich information on the underlying behavior of the moving targets. To this end we introduce an extension of Point Distribution Models (PDM) to analyze the object motion in their spatial, temporal and spatiotemporal dimensions. [...]
