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…

What is the best way to understand 'applies to' when it is said of a linguistic theory that it applies to a particular language-user? We can answer by saying that a linguistic theory is applicable to an individual language-user just…

The development of decision support systems for equipment diagnosis has been found to be an iterative process whereby functionality and knowledge are continually added to a prototype until satisfactory performance is achieved. In order to reduce both the dependency on…

Sadr al-Din Qunavi (605/1207-673AH/1274 CE)--stepson and pupil of Ibn $ rm sp{c}$Arabi (d. 638 AH/1240 CE)--played a pivotal role in the development of Islamic intellectual history. His contributions in the medieval period helped alter the course of mystico-philosophical tradition, which…

The purpose of this thesis is to evaluate the medical data management expert system at the Pediatric Intensive Care Unit of the Montreal Children's Hospital. The objective of this study is to provide a systematic method to evaluate and, progressively…

This study examines how prior knowledge influences future learning. Although it has been established that prior knowledge does have a strong impact on later learning, it is not clear how this effect manifests itself. Previous research suggests that one way…
