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 ...

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 ...

In this paper we provide a new proof of strong convergence of resolvent operators associated with boundary value problems on thin domains.

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, ...

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 ...

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 ...

We establish general conditions for the unique solvability of nonlinear measure functional differential equations in terms of properties of suitable linear majorants.

O presente trabalho é resultado de uma pesquisa de Iniciação Científica (com bolsa BAAE) que esteve focada no estudo da Geometria dos livros didáticos. Mais precisamente, foram analisados os capítulos que tratam dos temas ...

Este artigo apresenta breves considerações sobre uma pesquisa, ainda em desenvolvimento, que tem como cenário de investigação a Universidade Aberta do Brasil (UAB). Assim, tem-se como objetivo discutir como as tecnologias ...

The asymptotic stability of the null solution of the equation ẋ(t) = -a(t)x(t)+b(t)x([t]) with argument [t], where [t] designates the greatest integer function, is studied by means of dichotomic maps. © 2010 Academic Publications.
