Introdução ao método Monte Carlo: exemplos de aplicação
(Universidade Federal de Santa Maria, 2007-03-08)
In the present work, we study the Monte Carlo method in an introductory level. This method has been applied in models and systems whose results are known to compare with ours results. In the first part of this work, some ...
Análise dinâmica de um sistema para reprodução de contrabaixo elétrico
(Universidade Federal de Santa Maria, 2010-01-07)
In this work, I present a study done to assess the performance of a system designed to reproduce low-frequency acustical signals with improved definition to use with a electric bass. The analysis has been done by employing ...
Estudo da resposta magnética de materiais supercondutores por meio de medidas de susceptibilidade AC
(Universidade Federal de Santa Maria, 2010-12-09)
The study of magnetic properties of a superconducting material can be conducted by AC susceptibility measurements. In particular this paper, we present a theoretical review on the phenomenon of superconductivity, we introduce ...
Desenvolvimento de um magnetômetro de torque
(Universidade Federal de Santa Maria, 2007-02-27)
In this work a torque magnetometer was developed for the study of the magnetic anisotropy on magnetic materials. The system which composes the torque magnetometer is constituted basically by a torsional pendulum with an ...
Periodicidades no fluxo de raios cósmicos e análise de choques interplanetários
(Universidade Federal de Santa Maria, 2010-01-08)
Muons and neutrons that reach the Earth surface with high energy constitute a particles’ group called secondary cosmic rays. In order to study the flux of this particles data from muons and neutrons stations are used. The ...
Estudo teórico da estabilidade e propriedades eletrônicas de defeitos nativos em grafite BC2N
(Universidade Federal de Santa Maria, 2010-01-08)
The stability and electronic properties of antisites and vacancies are studied by spin polarized density functional calculations using generalized gradient approximation (GGA) to the exchange-correlation functional. We ...
Realizações não lineares da simetria quiral
(Universidade Federal de Santa Maria, 2010-12-09)
We study possible nonlinear realizations of chiral symmetry only in terms of isospin multiplets of the fields under consideration, isospin matrices and of the pion field, following closely the paper "Nonlinear Realizations ...
Flutuações de temperatura eletrônica em regiões HII: o caso de 30 Doradus revisitado
(Universidade Federal de Santa Maria, 2010-01-07)
In this work are presented measurements of the electron temperature in the HII region 30 Doradus derived from the [OIII](λ4959 + λ5007)/λ4363 ratio. Long-slit spectrophotometric data of high signal-to-noise, in the range ...
Caracterização estrutural, morfológica e estequiométrica de filmes finos de óxidos de vanádio
(Universidade Federal de Santa Maria, 2010-12-10)
The application of small angles X-Ray diffraction to the determination of thin film morfology is presented. Technical instrumental aspects that are relevant to the extraction of the diffraction data in this range have been ...
Avaliação dos termos da equação de balanço de fluxo de energia cinética turbulenta
(Universidade Federal de Santa Maria, 2015-07-09)
In this paper we propose a balance equation for turbulent flux of turbulent kinetic energy (TKE) in the planetary boundary layer (PBL) and its terms are evaluated through data generated by a numerical simulation model. ...
