El conocimiento de la composición biotípica de una población de áfidos es importante para poder
prevenir daños que se producirían en cultivares seleccionados por su resistencia al ataque de áfidos
de distintos tipos. Con el propósito de analizar la composición…

This article presents the confluence of two general ideas: Defeasible Logic Programming (DeLP, an argumentation based formalism for representing knowledge and reasoning) and Abduction in logic. In first place, we introduce a framework that formally states the problem of doing…

In this paper, the two-dimensional strip packing problem with 3-stage level patterns is tackled using genetic algorithms (GAs). We evaluate the usefulness of a greedy seeding procedure for creating the initial population, incorporating problem knowledge. This is motivated by the…

Although South America lost more megafaunal genera than any other continent during the Late-Quaternary Extinction event (LQE), little is known about the chronology, causes or dynamics of these extinctions, especially in the northern part of the continent. Fossil deposits in…

Background: Clinical examinations increasingly consist of composite tests to assess all aspects of the curriculum recommended by the General Medical Council.
Setting: A final undergraduate medical school examination for 214 students.
Aim: To estimate the overall reliability of a composite…

En el presente trabajo se busca caracterizar a los regantes de Río Segundo, Córdoba, en términos comparativos y en vinculación con la tecnología. Se trata de pequeños y medianos productores localizados en el Espinal cordobés, límite de la región pampeana…

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…

Denominada comumente cipó-de-fogo, Pyrostegia venusta é uma trepadeira por gavinhas, perene, empregada como ornamental devido às vistosas inflorescências de cor laranja, e como medicinal para o tratamento de diarréia e disenteria. Ensaios fitoquímicos identificaram alantoína, β-sitosterol e hesperidina na espécie.…

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…

In this work two declarative approaches based on the BDI theory are studied, an agent programming language 3APL and an agent architecture that uses defeasible argumentation for knowledge representation and reasoning. Based on that study and considering that in 3APL…
