Fluxo de coerência quântica para um qubit evoluindo sobre a ação de canais quânticos
(Universidade Federal de Santa Maria, 2016-08-23)
Quantum Coherence (QC) has a fundamental role in Quantum Mechanics (QM). It has
been studied since the emergence of QM. However, this quantum feature is easily destroyed
when a physical system interacts with the environment. ...
Comparação dos fluxos turbulentos em diferentes condições de estabilidade e topografia
(Universidade Federal de Santa Maria, 2004-05-04)
In this study sensible and latent heat fluxes as well as momentum flux were analysed in terms of similarity parameters. The intensity of the turbulence and the correlation functions are also studied. The data used in ...
Fluxo de metano na atmosfera sobre uma cultura de arroz irrigado por inundação no sul do Brasil
(Universidade Federal de Santa Maria, 2016-08-10)
The rice paddy is responsible for 12-16% of the anthropogenic emission of CH4 in the
world. Brazil is one of most important rice paddy producer. The goal of this study is to
understand the dynamics of methane exchange ...
