aprendizaje electrónico facilitan la reutilización de recursos educativos, así como al comunicación entre sistemas heterogéneos. En este número especial de IEEE RITA presentamos una selección de cinco trabajos realizados por renombrados expertos internacionales en este ámbito. La iniciativa de realizar esta publicación especializada surge de la Best Practice Network europea con el mismo nombre:...

Differing viewpoints concerning the specificity and generality of motor skill representations in memory were compared by contrasting versions of a skill having either extensive or minimal specific practice. In Experiments 1 and 2, skilled basketball players more accurately performed set shots at the foul line than would be predicted on the basis of the performance at the nearby locations, sugge...

A new concept, the multi level voltage/current reinjection is described in this paper. A voltage source converter is proposed, in which the multistep output voltage waveform is achieved by the reinjection of different DC voltage levels via the common neutral point of the converter bridges an 84-pulse voltage source converter (VSC), assembled by combining one twelve-pulse VSC, in conjunction wit...

In this technical report, we review related works and recent trends in visual vocabulary based web image search, object recognition, mobile visual search, and 3D object retrieval. Especial focuses would be also given for the recent trends in supervised/unsupervised vocabulary optimization, compact descriptor for visual search, as well as in multi-view based 3D object representation.
