Modelagem lagrangeana aplicada à dispersão de contaminantes em diferentes condições de estabilidade atmosférica
(Universidade Federal de Santa Maria, 2008-04-25)
In this dissertation, it was estimated contaminants concentration in different stability conditions of the Planetary Boundary Layer. In order to do this, it was used the Lagrangian stochastic model. The experiments by ...
Vidro de spin e antiferromagnetismo com interacão de pareamento BCS local
(Universidade Federal de Santa Maria, 2005-07-12)
In this work the competition among spin glass(SG), antiferromagnetism (AF) and BCS pairs formation (PAIR) in real space is investigated. The model consists of an Ising spin glass term and a local BCS term that favors double ...
