Design and optimization of distillation columns for ethanol dehydration, using a hydrocarbon as entrainer, implies a good knowledge of vapor-liquid (VLE), liquid-liquid (LLE) and vapor-liquid-liquid equilibrium (VLLE). Chemical process simulation programs always require the use of a thermodynamic model that…

Presentación de la aplicación de las nuevas tecnologías al análisis y la traducción de los clásicos catalanes., Aquesta investigació s’emmarca en el context del projecte de recerca per a la “Promoció exterior de la llengua, la literatura i la cultura…

The development of the novel form is an exploration of the possibilities for realistic
representation which is increasingly informed by an understanding that distortion and
fabrication are inevitable consequences of the mediating process of narrative. The search
for alternatives to…

In this work we present a reactive autonomous robot navigation system based only on omnidirectional vision. It does not rely on any prior knowledge about the environment apart from assuming a structured one, like indoor corridors or outdoor avenues. The…

Recently, existing design methodologies targeting traditional Web applications have been extended for Rich Internet Application modeling support. These extended methodologies currently cover the traditionally well-established design concerns, i.e. data and navigation design, and provide additional focus on user interaction and…

In this paper, a restricted domain question answering (QA) system is described. The design architecture of this QA system and the features that allow the adaptation of the QA system to the medical domain are also presented. The advantages of…

In this study I deal with the conception of "elocutio" as described and explained in the "Institutio oratoria". My main point of view is the semiotic one, since the analysis of syntactic, semantic, and pragmatic aspects of this rhetorical operation…

Aprender, desde un punto de vista sociocultural, está relacionado con cómo las personas se apropian de herramientas para pensar y actuar en una comunidad de práctica. Esta perspectiva del aprendizaje tiene implicaciones sobre el diseño de las tareas y entornos…

Virtual and remote laboratories(VRLs) are e-learning resources which enhance the accessibility of experimental setups providing a distance teaching framework which meets the student's hands-on learning needs. In addition, online collaborative communication represents a practical and a constructivist method to transmit…

Nuestro trabajo tiene como objetivo principal, la formulación de un modelo explicativo de la adquisición del aprendizaje complejo, y por extensión, del desarrollo inicial de la competencia
experta en un dominio específico. Modelo que tiene en cuenta los principales aspectos…
