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…

This study provides support to the characteristics of participatory and anticipatory stages in secondary school pupils’ abstraction of mathematical conceptions. We carried out clinical task-based interviews with 71 secondary-school pupils to obtain evidence of the different constructed mathematical conceptions (Participatory…

This paper uses dynamic general equilibrium and computational methods, inspired by the multi-sector growth model structure in Stephen Turnovsky's work, to develop a theory that unifies two of the traditional explanations of structural change: sector-biased technical change and non-homothetic preferences.…

The purpose of this investigation is to evaluate whether or not the allocation of time proposed in the Music Study Guide, adapted from the European Higher Education Area (EHEA) guidelines, is consistent and adequate for students with minimal musical knowledge.…

In this article we describe a novel algorithm that allows fast and continuous learning on a physical robot working in a real environment. The learning process is never stopped and new knowledge gained from robot-environment interactions can be incorporated into…

The analysis of changes in land cover and land use over time as sources of information and geographical diagnosis at a regional scale, is primary to improving knowledge of land cover and land use modelling in Mediterranean environments. The study…

Las listas de palabras con sus frecuencias se usan ampliamente en muchos procedimientos de agrupamiento y categorización de textos. Usualmente para la compilación de tales listas se usan las aproximaciones basadas en morfología (como el stemmer de Porter) para unir…

El artículo trata sobre el uso de información lingüística en la Desambiguación Semántica Automática (DSA). Proponemos un método de DSA basado en conocimiento y no supervisado, que requiere sólo un corpus amplio, previamente etiquetado a nivel morfológico, y muy poco…

Using an audiovisual perception task, two groups of native English listeners
(monolinguals, and L2 learners of Spanish) were asked to identify
which /p,t,k/ tokens had been produced by native English speakers
and which ones by foreigners. The experiment found that…

In this work we present a method to calculate the spectrum of the fundamental primaries of a digital camera from the experimental knowledge of its spectral sensitivities. The color triangle of the camera, linked to the chromaticities of its primaries,…
