Complex control tasks may be solved by dividing them into a more specific and more easily handled subtasks hierarchy. Several authors have demonstrated that the incremental layered evolution paradigm allows obtaining controllers capable of solving this type of tasks.

Many studies have focused on the concept of humanization of birth in normal
pregnancy cases or at low obstetric risk, but no studies, at our knowledge, have so far
specifically focused on the humanization of birth in both high-risk, and…

The United States education system is not meeting the needs of today’s youth, and
this is especially the case for minority and low socio-economic status youth. Although
there are a number of policy proposals that could improve youth academic performance,

Contexte: Les champignons mycorhiziens à arbuscules (AMF) établissent des relations symbiotiques avec la plupart des plantes grâce à leurs réseaux d’hyphes qui s’associent avec les racines de leurs hôtes. De précédentes études ont révélé des niveaux de variation génétique extrêmes…

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…

We have obtained photometry in B and R for seven confirmed or probable polar-ring galaxies from the Polar-Ring Catalog of Whitmore et al. (1990). The rings show a range of colors from B -R ≈ 0.6 to B - R…

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…

PET is a nuclear medical examination which constructs a three-dimensional image of metabolism inside the body; in this article is particular, images are taken from the brain. The high complexity inherent to the interpretation of the brain images makes that…

The theory change area have defined several operators trying to model the dynamic of knowledge. The goal of this work is to introduce a preprocessor of perceptions that could be part of an agent. The purpose of the preprocessor is…
