Ensino de polinômios no ensino médio uma nova abordagem
(Universidade Federal de Santa Maria, 2014-08-22)
This dissertation aims to propose a new approach in teaching polynomials. As this subject is worked in the last year of high school, we offer a proposal focused on higher education, but in an investigative and intuitive ...
Uso da base dinâmica em um sistema de duas vigas acopladas
(Universidade Federal de Santa Maria, 2013-08-26)
This work researches on free and forced vibrations of a double beam coupled system. The
system is regarded as two Euler-Bernoulli beams which are parallel, have the same length,
are simply supported and are connected ...
Teoria do funcional da densidade acoplada ao modelo de Hubbard de uma banda aplicada ao supercondutor La2−xSrxCuO4
(Universidade Federal de Santa Maria, 2020-09-15)
In this work we present the results of a methodology that combines first-principle Density
Functional Theory calculations with the Green’s functions method in order to treat strongly
correlated electronic systems. The ...

Pseudogap e energia cinética de supercondutores não convencionais descritos por um modelo de Hubbard em duas dimensões
(Universidade Federal de Santa Maria, 2020-03-30)
In conventional superconductors described by the Bardeen-Cooper-Schrieffer (BCS) Theory,
the transition from the normal to the superconducting state is accompanied by a reduction
in the potential energy and an increase ...

Bordo assintótico de superfícies mínimas em H2 × R
(Universidade Federal de Santa Maria, 2020-02-27)
In this work, we present some examples of minimal surfaces in H2 × R, and also a description
of the product and geodesic boundary of these surfaces. Our main goal is to
prove Theorem 5.1 of the Kloeckner and Mazzeo’s ...
Sistemas magnéticos com interações competitivas: uma abordagem de campo médio com clusters
(Universidade Federal de Santa Maria, 2020-04-27)
We study a model of localized spins which can assume three different states, S = 0 and
1, with two competing interactions: a antiferromagnetic first neighbour interaction (JA)
and a three body interaction between third ...
