Este trabajo sintetiza en tres ámbitos algunos de los resultados de las investigaciones sobre la construcción del conocimiento de la enseñanza de las matemáticas en entornos de aprendizaje multimedia que integran espacios de interacción social en contextos b-learning. Estos ámbitos…

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…

El proceso de informatizar el conocimiento necesario para conservar la biodiversidad de un país o región requiere de varias etapas de
desarrollo de sistemas de información. Típicamente se inicia con el manejo de datos en formatos analógicos y se continúa…

Our long-term, multi-country inventory explores the diversity of the subfamily Dynastinae (Coleoptera: Scarabaeidae) in a megadiverse region seriously imperiled by deforestation, invasive species, and urbanization. The project’s objectives are (1) study and document the diversity, spatial and temporal distributions, and…

This paper describes the overall architecture of Episteme, a tool for the development of efficient LFG-based MT systems following the classical transfer approach. The
system incorporates a series of novel computational techniques which enhance the overall performance significantly: representation, storage…

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…

As stated at the start of this article, psychological and physical demand states can be understood as the effects and consequences caused by loads. To deduce the physiological characteristics of psychophysical demand, theoretical concepts like the load/demand concept are commonly…

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,…

La investigación cualitativa en el campo de la salud se enfrenta a problemas relativos a la producción de conocimiento científico o la cuestión epistemológica, los procedimientos metodológicos en la indagación cualitativa, y la utilidad y uso de los hallazgos cualitativos.…

An exploratory analysis was carried out to describe patient satisfaction with ambulatory care. The analysis aimed at gaining an understanding of satisfaction with the care received from the patient's perspective; it was guided by the principles of qualitative analysis. Findings…
