Current reasoning systems attempt to model an agent's knowledge and interaction with its environment in a symbolic manner. This environment, its world is generally dynamic and changing due to natural evolution or the actions of other agents that are a…

Artificial Intelligence has long dealt with the issue of finding a suitable formalization for reasoning with incomplete and potentially inconsistent information. Defeasible argumentation [SL92,CML00,PraVre99] has proven to be a successful approach in many respects, since it naturally resembles many aspects…

Se presentan ocho fechados 14C-AMS sobre colágeno de huesos craneanos sin alteración diagenética, provenientes de la cueva de Haichol, Neuquén, que serán discutidos con el propósito de adquirir conocimientos más precisos relativos a cronología, paleodieta, entorno paleoambiental del sitio y…

This paper summarizes the main results developed in the author's PhD Thesis.
The main goal of the Thesis is to provide a formalization of defeasible argumentation oriented towards its computational treatment. In order to do this, an LDS-based logical framework…

En este trabajo se analizan los símbolos y representaciones del proceso de gestación entre los tobas de la provincia de Formosa poniendo especial énfasis en sus transformaciones e interrelaciones con las instituciones y representaciones biomédicas. Se considera el simbolismo del…

The main characteristics of Darwin's life and work will be examined, as well as the developments which occurred after his death, especially neodarwinism and the synthetic theory of organic change. In which ways the extraordinary progress made in the field…

The Semantic Web purports to give computeraccessible meaning to the content of the World Wide Web. The rationale behind this project is to create an environment where all this information could be freely exchanged among diverse entities, yet retaining its…

It is interesting and important to compare, analyze and assess the alternative tools that could be used in the area of Knowledge Representation. In this paper we present a reasearch line associated to this goal: to formally establish the relation…

The goal of this work involves the developing of an argumentation-based formalism that an agent could use for constructing plans. In this formalism, agents will have certain knowledge about the world, and a set of actions that they will be…

Este articulo revisa sintéticamente algunos trabajos y analiza resultados preliminares propios, dando a conocer el estado actual del conocimiento en relación con el grado de repercusión de la porosidad sabre las propiedades mecánicas en tracción. El análisis se ha realizado…
