Adaptive finite element methods (FEM) have been widely used in applications for over 20 years now. In practice, they converge starting from coarse grids, although no mathematical theory has been able to prove this assertion. Ensuring an error reduction rate…

A new computable a posteriori error estimator is introduced, which relies on the solution of small discrete problems on stars. It exhibits built-in flux equilibration and is equivalent to the energy error up to data oscillation without any saturation assumption.…

Data oscillation is intrinsic information missed by the averaging process associated with finite element methods (FEM) regardless of quadrature. Ensuring a reduction rate of data oscillation, together with an error reduction based on a posteriori error estimators, we construct a…

A produção animal nos ecossistemas do semi-árido é influenciada pela variabilidade espacial e interanual da oferta quantitativa e qualitativa de recursos forrageiros. A dinâmica da acumulação de fitomassa para a maioria das diferentes espécies da caatinga é pouco conhecida, o…

In developing telephone-based conversational systems, we foresee future systems capable of supporting multiple domains and flexible vocabulary. Users can pursue several topics of interest within a single telephone call, and the system is able to switch transparently among domains within…

This paper presents a group of elements to improve the teaching and learning in technological education, applied to Information and Communication Technologies (ICT). These elements are based on some contributions issued from contemporary education models, namely, the thematic approach, meaningful…

The Sami people have struggled for centuries to maintain their culture in spite of pressures against it from colonialism. The formal education systems of Norway and Finland have acted in discord with Sami decision-making since their inception. In response to…

Research in decision making has identified the importance of prior knowledge and heuristics on decision making behaviour. These develop with experience in a fashion similar to how domain experts develop specialized knowledge structures and heuristic reasoning patterns. This research is…

The aim of this study is to test the assumption that the depictions of ancient boxing found on Attic Black and Red Figure pottery are accurate. Due to the scarcity of ancient written material and physical evidence, most of our…
