Cómo crear una actividad H5P de ordenar los párrafos en el Aula Virtual
2022
En este videotutorial se muestra cómo crear una actividad H5P de ordenar los párrafos en el Aula Virtual (Moodle 3.11). Este trabajo forma parte del Proyecto de Innovación Docente Multimedia learning objects in moodle: Sustainable Development Goals (Ref: UV-SFPIE_PID-1640789) financiado por el Vicerrectorado de Ocupación y Programas Formativos de la Universitat de València en el curso académico 2021/2022.
Evolution des paysages Sahélines au cours des six dernières décennies dans la région de Niamey : de la disparition de la brousse tigrée à l'encroutem…
2010
In the Sahel, the rapid increase of the population during the last decades and the climate variation lead to an important environmental degradation. This work aims to measure the impacts of the human pressure on ecosystem during the six last decades. A diachronic cartography of a 100 km² area close to Niamey was done with aerial photographs (1950 and 1975) and GPS measurements (2009). Results showed that the tiger bush vegetation was completely cleared between 1950 and 2009 while the fallow decreases from 7 % to 1 %. In the sandy valley, the increase of cultivated fields from 20,7 % (1950) to 69,4 % (1975) favoured wind and water erosions which allowed surface soil crusting. Between 1975 an…
Filipinas en el marco del imperio español en el siglo XIX
2019
[EN] En este artículo se analiza la evolución de Filipinas en las últimas décadas del siglo XVIII y en el transcurso del siglo XIX a través de diferentes epígrafes: la obligada transformación del secular modelo colonial volcado hacia el tráfico del Galeón y las relaciones transpacíficas; la renovada inclinación hacia Asia, el océano Índico y el mar de China; el desarrollo de un sistema económico basado en la exportación de productos filipinos y en la apertura de las islas al exterior; la evolución de la vida política; el camino hacia la modernización; el peso de las órdenes religiosas, la importancia de la población china y la colaboración con élites indígenas como rasgos singulares de Fili…
Skeleton-Based Multiview Reconstruction
2016
International audience; The advantage of skeleton-based 3D reconstruction is to completely generate a single 3D object from well chosen views. Having numerous views is necessary for a reliable reconstruction but projections of skeletons lead to different topologies. We reconstruct 3D objects with curved medial axis (whose topology is a tree) from the perspective skeletons on an arbitrary number of calibrated acquisitions. The main contribution is to estimate the 3D skeleton, from multiple images: its topology is chosen as the closest to those of the perspective skeletons on the set of images, which means that the number of topology changes to map the 3D skeleton topology to topologies on im…
Key-points to evaluate correctly the placement of umbilical venous catheters in infants on frontal radiographs
2015
Provide basic key-points to evaluate placement of umbilical venous catheters (UVC) using a simplified flow-chart in resident radiologist.
Univariate and multivariate properties of wind velocity time series
2009
We analyze the time series of hourly average wind speeds measured at 29 different stations located in Sicily, a region with a complex morphology. The investigation, performed from the univariate as well as the multivariate point of view, evidences that the statistical properties of wind at the single sites have features that are not reproduced by standard models and, thus, require specific modeling. Moreover, the synchronous evolution of wind velocity presents a cluster structure, obtained with different algorithms, that persists in the standard deviation too.
