O teorema de Cauchy na mecânica dos fluidos
(Universidade Federal de Santa Maria, 2010-12-21)
The present work shows Cauchy's Theorem on its classical form, and it has the objective of weakening their statements, and provides aplications in continuum mechanics. The metodology used here is the axiomatic, that is, a ...
Autofunções e frequências de vibração do modelo Euler-Bernoulli para vigas não-clássicas
(Universidade Federal de Santa Maria, 2011-07-18)
This paper presents a methodology for determining eigenfunctions and frequencies
of the Euler-Bernoulli model for elastic beams that can include damping and devices
located at intermediate or end points of the beam. The ...
Hélices, curvas de Bertrand e superfícies regradas
(Universidade Federal de Santa Maria, 2012-02-27)
This work is designed to study helices and Bertrand curves. A circular helix is characterized by having constant curvature k 6= 0 and constant torsion t . If the ratio t k is constant, the curve is called generalized helix. ...
Um estudo sobre condições para existência e multiplicidade de soluções para problemas do tipo Ambrosetti-Prodi
(Universidade Federal de Santa Maria, 2015-08-10)
The aim of this work is to establish conditions for the existence and multiplicity of solutions
for Ambrosetti-Prodi problems type involving pLaplacian operator with subcritical growth
related to the Sobolev critical ...
Existência de soluções para um problema do tipo (p; q)-Laplaciano com perturbação
(Universidade Federal de Santa Maria, 2015-08-10)
In this paper, considering _ RN (N > 2) a bounded smooth domain, using blow-up
techniques and the Leray Schauder Topological Degree theory, we intend to ensure the
existence of positive solutions for a problem involving ...
Resolubilidade global de operadores lineares com coeficientes constantes
(Universidade Federal de Santa Maria, 2013-07-15)
In this dissertation we present a proof of a Bernard Malgrange theorem, which
establishes a necessary and sufficient condition for the global solvability of a linear
operator with constant coefficients.
Pares admissíveis, sistemas admissíveis e biálgebras na categoria dos módulos de Yetter-Drinfeld
(Universidade Federal de Santa Maria, 2014-03-19)
The purpose of this work is to study the relationships between admissible pairs, systems admissible and bialgebras in the category of Yetter-Drinfeld modules, as well as some properties of the Hopf algebra associated (via ...

O teorema de Cauchy em equações de Navier-Stokes
(Universidade Federal de Santa Maria, 2013-03-08)
This work presents the Cauchy's theorem in its classical form, and aims to weaken their
hypotheses, providing a more advantageous use in continuum mechanics. The methodology
is axiomatic, that is, basic concepts are ...
Estudo das vibrações transversais em um sistema viscoelástico acoplado de duas cordas
(Universidade Federal de Santa Maria, 2013-11-22)
In this work, it is developed a study of the transverse vibrations of a system composed
by two parallel strings of equal length, coupled by a viscoelastic element. The frequencies
and mode shapes are obtained using modal ...
