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…

The chemical effects of acoustic cavitation are obtained in sono-reactors built-up from a vessel and an ultrasonic
source. In this paper, simulations of an existing sono-reactor are carried out, using a linear acoustics model, accounting
for the vibrations of the…

An automatic disassembly cell requires of a
computer vision system for recognition and localization of
the products and each of theirs components. The detection
of occlusions adds more information to the knowledge base
to identify components and products, and generate…

This article overviews the concepts of distributed intelligence, outlining the motivations for studying this field of research. First, common systems of distributed intelligence are classified based upon the types of interactions exhibited, since the type of interaction has relevance to…

In this paper a cross-disciplinary study of the use of epistemic markers as hedging rhetorical strategies in research articles in English is carried out. Based on computer readable data, and combining quantitative and

There are different approaches used by mathematics teacher educators to help pre-service primary teachers develop the useful skills and knowledge required to teach mathematics. One of these approaches is concerned to learning to notice relevant aspects in mathematics teaching. But…

Social knowledge is one of the key aspects of MAS in order to face complex problems in dynamical environments. However, it is usually incorporated without specific support on behalf of the platform and that does not let agents take all…

Este artículo presenta un nuevo método totalmente automático de
construcción de bases de conocimiento muy densas y precisas a partir de recursos
semánticos preexistentes. Básicamente, el método usa un algoritmo de Interpretación Semántica de las palabras preciso y de amplia…

En muchas bases de conocimiento para el PLN prevalece actualmente un enfoque lexicista. En cambio, FunGramKB utiliza la ontología como módulo pivote entre los niveles léxicos y cognitivos, convirtiéndose así en el componente más importante. El propósito de este artículo…
