The USAID and the teaching of mathematics in Rio Grande do Norte
(Bolema-mathematics Education Bulletin-boletim De Educacao Matematica, 2008-01-01) [Artigo]
In the 1960s occurred great changes in the general education and, specially in the mathematical teaching, throughout Brazil. Besides the Law Diretrizes e Bases for Education (law 4024/1961), such changes also was occurred ...
Trends in Brazilian academic production in the History of Mathematics Education: directions from EBRAPEM
(Bolema-mathematics Education Bulletin-boletim De Educacao Matematica, 2009-01-01) [Artigo]
The number of papers on History of Mathematics Education presented at EBRAPEM (Brazilian Meeting of Graduate Students in Mathematics Education) has increased significantly between 2003 and 2008. This article presents a ...
VOICES FROM THE SOUTH: DIALOGICAL RELATIONSHIPS AND COLLABORATION IN MATHEMATICS EDUCATION
(Internationalisation and Globalisation In Mathematics and Science Education, 2007-01-01) [Artigo]
This chapter presents a collaborative experience between two neighbouring countries from South America: Argentina and Brazil. Our purpose is to share a model of international collaboration that we consider to be an alternative ...
On an approximate analytical solution to a nonlinear vibrating problem, excited by a nonideal motor
(Nonlinear Dynamics, 2007-12-01) [Artigo]
This paper analyzes through Multiple Scales Method a response of a simplified nonideal and nonlinear vibrating system. Here, one verifies the interactions between the dynamics of the DC motor (excitation) and the dynamics ...
The relationship between differential equations with piecewise constant argument and the associated discrete equations, via dichotomic maps
(Dynamics of Continuous, Discrete and Impulsive Systems Series A: Mathematical Analysis, 2005-12-01) [Artigo]
Dichotomic maps are considered by means of the stability and asymptotic stability of the null solution of a class of differential equations with argument [t] via associated discrete equations, where [.] designates the ...
A NOTE ON RESOLVENT CONVERGENCE ON A THIN DOMAIN
(Bulletin Of The Australian Mathematical Society, 2014-02-01) [Artigo]
In this paper we provide a new proof of strong convergence of resolvent operators associated with boundary value problems on thin domains.
A scalable re-ranking method for content-based image retrieval
(Information Sciences, 2014-05-01) [Artigo]
Content-based Image Retrieval (CBIR) systems consider only a pairwise analysis, i.e., they measure the similarity between pairs of images, ignoring the rich information encoded in the relations among several images. However, ...
Husserl's phenomenology and Weyl's predictivism
(Synthese, 1997-02-01) [Artigo]
In this paper I discuss the version of predicative analysis put forward by Hermann Weyl in Das Kontinuum. I try to establish how much of the underlying motivation for Weyl's position may be due to his acceptance of a ...
Ser e tornar-se professor: práticas educativas no contexto escolar

Functions and vector fields on C(CPn)-singular manifolds
(Ukrainian Mathematical Journal, 2014-08-01) [Artigo]
Let M2n+1 be a C(CPn) -singular manifold. We study functions and vector fields with isolated singularities on M2n+1. A C(CPn) -singular manifold is obtained from a smooth manifold M2n+1 with boundary in the form of a ...
