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…

We develop a theory to explain the transition from stagnation to modern growth. We focus on the forces that shaped the evolution of total factor productivity in agriculture and manufacturing across history. More specifically, we build a multisector model of…

The construction of a teenager population’s citizenship identity is influenced by the cultural and social capital belonging to every student, as well as by two aspects of school organisation. On the one hand, there is an academic contribution motivated by…

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…

In this paper we present different error measurements with the aim to evaluate the quality of the approximations generated by the GNG3D method for mesh simplification. The first phase of this method consists on the execution of the GNG3D algorithm,…

Tanto en sus escritos narrativos como en los políticos, sociológicos e históricos, es posible percibir en José Victorino Lastarria un idealismo latente –cifrado en la máxima «combatir la ignorancia»– que va construyendo una filantropía señera en las coordenadas latinoamericanas. La…

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…
