Se compone de diez actividades destinadas a ayudar a los profesores a desarrollar las capacidades de análisis e interpretación de datos de los alumnos de ciencias. Cada actividad incluye una hoja de preguntas y una hoja de datos, ésta última, disponible en archivos de Excel, para que los estudiantes utilicen las nuevas tecnologías para crear gráficos. Los ejercicios están pensados para el nivel superior de la etapa 2 (key stage 2) del currículo nacional inglés y para la etapa 3, es decir, para primaria y secundaria, y se centran en el contenido de 'Sc2 Life and Living Proceses'.

We present algorithms for computing approximate distance functions and shortest paths from a generalized source (point, segment, polygonal chain or polygonal region) on a weighted non-convex polyhedral surface in which obstacles (represented by polygonal chains or polygons) are allowed. We also describe an algorithm for discretizing, by using graphics hardware capabilities, distance functions. Finally, we present algorithms for computing discrete k-order Voronoi diagrams

This paper deals with the relationship between the periodic orbits of continuous maps on graphs and the topological entropy of the map. We show that the topological entropy of a graph map can be approximated by the entropy of its periodic orbits

The identification, tracking, and statistical analysis of tropical convective complexes using satellite imagery is explored in the context of identifying feature points suitable for tracking. The feature points are determined based on the shape of complexes using the distance transform technique. This approach has been applied to the determination feature points for tropical convective complexes identified in a time series of global cloud imagery. The feature points are used to track the complexes, and from the tracks statistical diagnostic fields are computed. This approach allows the nature and distribution of organized deep convection in the Tropics to be explored.
