We prove that a polar orthogonal representation of a real reductive algebraic group has the same closed orbits as the isotropy representation of a pseudo-Riemannian symmetric space. We also develop a partial structural ...

The representation of the Brazilian Umbanda religion is discussed from the point of view of the Theory of Social Representations. It is considered that Universal Classification Systems, such as the CDD, do not adequately ...

This paper highlights three different interrelations between Literature and History: a) the one that subordinates literary art to the patterns of history as a kind of scientific discourse (historiography); b) the one that ...

This paper deals with the analysis and simulation of an electric vehicle, coupling functional and structural approaches in the same simulation environment. The Bond Graph model, the structural approach, is first deduced ...

This work introduces Extended Defeasible Logic Programming (E-DeLP), a structured argumentation system enabling the expression of reasons for and against using defeasible rules. E-DeLP extends the formalism of Defeasible ...

This research discusses values shared by teachers of basic education in the practice of the profession, taking them as responsible for the connection between the constructs individual attitudes and social structure that ...

We introduce a dynamic data structure for the compact representation of binary relations R subset of A x B. The data structure is a dynamic variant of the k(2)-tree, a static compact representation that takes advantage of ...

Specific choices about how to represent complex networks can have a substantial impact on the execution time required for the respective construction and analysis of those structures. In this work we report a comparison ...
