Los cambios registrados en el clima durante las últimas décadas están afectando a la distribución y dinámica poblacional de las especies a una escala global, induciendo cambios en la fenología, en el crecimiento o en las interacciones bióticas. Estas alteraciones…

This article reviews existing knowledge concerning the epidemiology, instruments and regulatory criteria currently used to evaluate artificial turf soccer pitches. Recent years have seen tremendous growth in the use of artificial turf as a playing surface for sports (rugby, soccer,…

When building Hypermedia/Web Applications, (different) designers are often faced with the same problems over and over again. Those recurring problems soon yield elegant solutions, which can be conveniently described as design patterns. In this paper we present two patterns for…

An audience driven philosophy for web site design takes the different target audiences as an explicit starting point, and organizes the basic navigation structure accordingly. However, for the designer it is not always easy, or sometimes even impossible, to assess…

The ability of building robust semantic space representations of environments is crucial for the development of truly autonomous robots. This task, inherently connected with cognition, is traditionally achieved by training the robot with a supervised learning phase. We argue that…

When training hidden-Markov-model-based part-of-speech (PoS) taggers involved in machine translation systems in an unsupervised manner the use of target-language information has proven to give better results than the standard Baum-Welch algorithm. The target-language-driven training algorithm proceeds by translating every possible…

En el trabajo se analizan las consecuencias de la crisis económica internacional de 2008 sobre el turismo en el destino Rio Grande do Norte (Brasil), dedicándose especial atención a los efectos de esta crisis y a las medidas implantadas para…

La construcción del propio aprendizaje es una tarea que debemos fomentar desde los Centros Docentes Universitarios y no Universitarios, con el fin de poder llevar a cabo un proceso de enseñanza lo más significativo posible. En este caso, se aborda…

Heterogeneous azeotropic distillation is a widely used technique to separate binary azeotropic mixtures into their components. One of its most important applications is the dehydration of ethanol, which is blended with gasoline to obtain automobile fuel. Among all the compounds…

Geographic knowledge discovery (GKD) is the process of extracting information and knowledge from massive georeferenced databases. Usually the process is accomplished by two different systems, the Geographic Information Systems (GIS) and the data mining engines. However, the development of those…
