El presente artículo aborda los cambios en los espacios rurales de América Latina y los posibles escenarios futuros a través de estudios de caso desarrollados en el contexto del proyecto "Designing a methology to evaluate local knowlegde on global change…

Lakes are excellent sensors of environmental change, including climate change. Chironomids (Insecta, Diptera) and ostracods (Crustacea) are among the most useful biological indicators for paleoenvironmental reconstruction found in lake sediments, due to their sensitiveness to environmental variables. However, the use…

Corallus annulatus (Northern Annulated Tree-boa) is a little-studied tropical Boid occurring disjunctively throughout Central America and tropical South America in mostly lowland tropical moist and wet forests (Holdridge, 1967; Stafford & Henderson, 1996; Smith & Acevedo, 1997; Henderson et al.,…

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…

Inventários faunísticos são fundamentais para o conhecimento da biodiversida- de e, conseqüentemente, para o planejamento e tomada de decisões sobre estratégias de conser- vação. Para conhecer a diversidade e composição dos répteis Squamata, assim como a distribuição das espécies por…

The development of systems with the ability to reason about change notion and actions has been of great importance for the artificial intelligence community. The definition and implementation of systems capable of managing defeasible, incomplete, unreliable, or uncertain information has…

La obtención de conocimiento a partir de la información existente es un proceso no trivial que consiste en identificar patrones válidos, novedosos, potencialmente útiles y comprensibles a partir de los datos disponibles. La Minería de Datos es el área de…

In these days most robotic systems tend to be complex to maintain and reuse because existing frameworks are based mainly on code-driven approaches. This means the software development process is reduced to the implementation of systems using specific programming languages.…

In the last decade several ways to formalize defeasible reasoning have been studied. A particular approach, defeasible argumentation, has been particularly successful to achieve this goal.
The inference process of argument-based systems is based on the interaction of ar- guments…

A fuzzy controller is usually designed by formulating the knowledge of a human expert into a set of linguistic variables and fuzzy rules. As it is well known, the use of prior knowledge can dramatically improve the performance and quality…
