A fast marching method for the area based affine distance
(Springer, 2008-01)
In a previous paper, it was proved that the area based affine distance of a convex region in the plane satisfies a non-homogeneous Monge-Ampere differential equation. Based on this equation, in this paper we propose a fast ...
Area distances of convex plane curves and improper affine spheres
(Siam Publications, 2008)
The area distance to a convex plane curve is an important concept in computer vision. In this paper we describe a strong link between area distances and improper affine spheres. Based on this link, we propose an extremely ...
Towards a framework for corporate e-learning evaluation
(2007)
The main focus of current researches is on technological and pedagogical aspects of web based learning. However, e-learning is a complex process that incorporates organizational, administrative, instructional, and technological ...
Analysing users' access logs in Moodle to improve e learning
(2007)
In this work the UFSC (Federal University of Santa Catarina) and the FGV-RJ (Fundação Getúlio Vargas do Rio de Janeiro) jointly propose the use of a data mining tool to support the analysis of trends, students profiles, ...

Lessons learnt from an unsuccessful G2G endeavor in brazil
(2006)
In recent years, many governments have seized the moment provided by Information Technology as the ideal opportunity to rethink their administrative praxis. This restructuring concentrates not only on the internal aspects ...
Binarization algorithms for approximate updating in credal nets
(Ios Press, 2006)
Credal networks generalize Bayesian networks relaxing numerical parameters. This considerably expands expressivity. but makes belief updating a hard task even on polytrees. Nevertheless, if all the variables are binary, ...
An active symbols theory of chess intuition
(Springer, 2005-05)
The well-known game of chess has traditionally been modeled in artificial intelligence studies by search engines with advanced pruning techniques. The models were thus centered on an inference engine manipulating passive ...
A multiple-population evolutionary approach to gate matrix layout
(Taylor & Francis Ltd, 2004-01-15)
This paper deals with a Very-Large-Scale Integrated systems design problem that belongs to the NP(Nondeterministic Polynomial)-hard class. The Gate Matrix Layout problem has numerous applications in the chip-manufacturing ...
