Caracterização fotométrica de aglomerados estelares nas regiões W 31 e NGC 6334
(Universidade Federal de Santa Maria, 2018-03-06)
Stellar clusters are groups of gravitationally bounded stars which were born from the same molecular
cloud. In their initial phase, they remain bounded to the cloud and are called embedded
clusters. These objects have ...
Simulação do comportamento superhidrofóbico em rampas de pilares
(Universidade Federal de Santa Maria, 2014-08-28)
We present a two-dimensional simulation based on the cellular Potts model
(CPM) of the properties of smooth and pillar structured hydrophobic surfaces. For a
surface having superhidrophobic behavior, a drop ...
Anisotropias magnéticas em filmes finos de Co: uma análise por magnetometria de torque
(Universidade Federal de Santa Maria, 2010-12-03)
By studying the magnetic behavior of materials a very important parameter to be analyzed are the constants of anisotropy. They can be associated with an effective anisotropy energy or to a more specific one as, for example, ...
Estudo computacional da viscosidade da água confinada em nanotubos de carbono
(Universidade Federal de Santa Maria, 2015-02-27)
When confined in nanometer scale, water presents great variation in their dynamic
properties. Here, we carried out molecular dynamics simulations to determine
the ratio of the diffusion coefficient and viscosity variation ...
Feedback de AGN em galáxias do Projeto Manga: uma análise da distribuição e cinemática do gás ionizado
(Universidade Federal de Santa Maria, 2019-10-21)
By the end of the XX century, large data surveys began due to the development of powerful
telescopes. The Sloan Digital Sky Survey (SDSS) is one of these surveys and comprehend
subprojects like the Mapping Nearby Galaxies ...
Dinâmica das propriedades térmicas e do fluxo de calor no solo em uma área de pastagem no bioma Pampa
(Universidade Federal de Santa Maria, 2017-08-07)
For the thermal characterization of a soil it is necessary to determine its thermal properties,
because they describe how the storage and the propagation of thermal energy vary
a function of time and depth. This knowledge ...
Aperfeiçoamento de modelos numéricos para estimativa de propriedades térmicas do solo
(Universidade Federal de Santa Maria, 2019-09-02)
Understanding the soil thermal properties, in particular, diffusivity , volumetric capacity and conductivity is important in applications of several related areas, mainly soil-plant-atmosphere interaction. Studies to ...
Desenvolvimento de um modelo lagrangiano para estimar a dispersão de escalares passivos em condições de meandro do vento horizontal
(Universidade Federal de Santa Maria, 2017-02-24)
The description of the effects of the wind meandering in the scalar dispersion is a challenging
task, since this type of flow represents a physical state characterized by multiple
scales. In this study, a Lagrangian ...
Tomografia PCA aplicada a cubos de dados no infravermelho próximo para a galáxia Seyfert Mrk 1066
(Universidade Federal de Santa Maria, 2014-06-30)
In this work, we apply the PCA Tomography technique (Principal Component Analysis) to data
cubes for the central region of the Seyfert 2 galaxy Mrk 1066. The observations were done with
the NIFS (Near-infrared Integral ...
Pseudogap e calor específico de um modelo de hubbard repulsivo
(Universidade Federal de Santa Maria, 2014-08-15)
The specific heat and the condensation energy of a two-dimensional Hubbard model,
suitable to discuss high Tc superconductors (HTSTC), is studied taking into account
hopping to first (t) and second (t2) nearest neighbors. ...
