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…

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…

PET is a nuclear medical examination which constructs a three-dimensional image of metabolism inside the body; in this article is particular, images are taken from the brain. The high complexity inherent to the interpretation of the brain images makes that…

Most Natural Language Processing (NLP) systems traditionally use a sequential architecture that represents the classical linguistic levels (lexical-morphological, syntactical, semantic, etc.), but they claim for huge and monolithic modules, that make the backtracking among such modules difficult. By using a…

This paper presents the automatic extension of TERSEO to other languages,
a knowledge-based system for the recognition and
normalization of temporal expressions, originally developed for
Spanish.

TERSEO was extended to English and Italian through the
automatic translation of the…

This paper presents an interactive computer simulator that can be used in the
field of practical training in Robotics. The tool can provide basic training for workers as
well as increase their knowledge about robotic concepts. The application offers a…

Descripción de un proyecto en el que mediante la filología y la traducción a múltiples lenguas, aplicando las nuevas tecnologías, se profundiza en el conocimiento de los clásicos valencianos.

Global discourse structures and local discourse relations are complementary modes of textual organization which an automated text generation system must account for and treat as interactive knowledge resources. To illustrate this interaction, we analyse a medical case report in terms…

This paper focuses on the general problem of the lexical bottleneck and, in particular, on the issues of semantic clustering and disambiguation by means of word usage cues obtained from sublanguage-specific corpora. Our approaches combines the use of numerical techniques…

The use of simple (S)-proline as catalyst for the intermolecular direct aldol reaction at the beginning of this century became a
true milestone in the growth of organocatalysis as a useful synthetic strategy. Since then, a plethora of new organocatalytic…
