Arquitetura ponte-filtro para segurança em simulação distribuída multinacional
(Universidade Federal de Santa Maria, 2020-01-16)
Forming alliances and government agreements for military training among different
countries increases the need for security controls in simulators interoperability. Military
simulators may have information such as weapons ...
Um processo para casamento de esquemas de documentos JSON baseado na estrutura e nas instâncias
(Universidade Federal de Santa Maria, 2020-02-10)
Historically, schema matching has been studied a lot, but it still presents many difficulties
resulting from countless conflicts and problems. Approaches for NoSQL databases (Not
Only SQL) are still poorly studied, given ...
Sistema integrado de baixo consumo para aquisição de ECG e cálculo da VFC
(Universidade Federal de Santa Maria, 2020-02-19)
This work proposes a low power consumption analog front-end to acquire ECG signals and
calculate heart rate variability (HRV), which has several biomedical applications. Many QRS
detectors use digital techniques (software) ...
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 ...
Um pipeline de redução de dados espectroscópicos para eventos de quilonova
(Universidade Federal de Santa Maria, 2020-11-09)
This work presents the process of making a pipeline for the reduction of longslit spectroscopic
data, acquired with the GMOS instrument of the Gemini Observatory as part of the optical
follow-up of kilonovae candidates. ...
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 ...
Existência e regularidade de soluções fundamentais para operadores diferenciais lineares de coeficientes constantes
(Universidade Federal de Santa Maria, 2020-03-19)
The main objective of this dissertation is to present a theorem that guarantees the existence
and regularity of fundamental solutions for linear differential operators with constant
coefficients. We also present some of ...

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 ...
