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. ...

(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.
A solução fundamental na obtenção das frequências naturais e autofunções de um sistema de viga dupla Euler-Bernoulli com camada elástica e força axial
(Universidade Federal de Santa Maria, 2022-08-18)
In this work we approach a double Euler-Bernoulli beam system with axial force coupled by
an elastic layer. We performed a matrix formulation for the system of equations and for the
boundary conditions, which allows ...
Modelos epidemiológicos em tempo discreto
(Universidade Federal de Santa Maria, 2022-08-25)
In an endemics, an infeccious disease remains prevalent, in low levels, in a population. In this
work, three discrete time mathematical models for an endemic disease are studied: the SIR,
the SEIR and SEIRS models. For ...
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 ...
