Frequently we become amazed with the increasing number of problems to be solved that fiourish while facing daily activities. Often, related to these problems we llave also an incredible amount oí data. Since we cannot allways afford time and resources…

This paper presents a proposal for an architecture that integrates knowledge discovery systems (automatic acquisition) and knowledge based systems (experts systems). This work formulates considerations over the viability of the implementation of this architecture according to the advance of the…

Evolutionary algorithms (EAs) are merely blind search algorithms, which only make use of the relative fitness of solutions, but completely ignore the nature of the problem. Their performance can be improved by using new multirecombinative approaches, which provide a good…

Los lagartos del género Liolaemus se distribuyen desde las altas cordilleras de Perú y Bolivia en el norte hasta el extremo austral de América del Sur. Se analizan los cariotipos descriptos para las 55 especies de Liolaemus con análisis citogenético…

The design of intelligent agents is a key issue for many applications. Since there is no universally accepted definition of intelligence, the notion of rational agency was proposed by Russell as an alternative for the characterization of intelligent agency.

Most formalisms for representing common-sense knowledge allow incomplete and potentially inconsistent information. When strong negation is also allowed, contradictory conclusions can arise. A criterion for deciding between them is needed. The aim of this paper is to investigate an inherent…

Fontes de informações sobre medicamentos são na maioria das vezes inacessíveis aos usuários e
quando disponíveis existe uma barreira relativa ao conhecimento técnico, na maioria das vezes exigido para
a compreensão destas. Os centros de informações sobre medicamentos aparecem como…
