Teorias de Spin-1: decomposição em helicidades, redução dimensional e imersão de calibre
(Universidade Estadual Paulista (Unesp), 2015-03-05)
We have studied the physical content of the following models: Maxwell, Proca, Self-Dual and Maxwell-Chern-Simons. One method we have used is the decomposition in the so called helicity variables, which can be done in the ...
Nonlinear dimensionality reduction frameworks to support machine learning systems
(2011)
En este trabajo se presentan algunos esquemas de reducción de dimensión no lineal (RDNL) basados en aprendizaje por variedades. En este sentido, se pretende identificar adecuadamente la información relevante del fenómeno ...
Hipoelipticidade, resolubilidade e formas normais para campos vetoriais no toro
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2015-04-24)
The main aim of this work is to study a class of real vector elds de ned on a torus, where the concepts of global hypoellipticity, global C1 solvability and reduction to its normal form are equivalents. We also study a ...
Confinamento de partículas quânticas a curvas do espaço
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Matemática - PPGM, 2010-05-24)
In this work we study dimensional reductions in some quantum systems; such reductions occur due to confinement of the particle from a tube in space to a curve. Our main goal is to find the effective hamiltonian operator ...
Análise proteômica e morfológica em fígado de ratos submetidos à exposição ao chumbo e suplementados com ferro
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Genética Evolutiva e Biologia Molecular - PPGGEvCâmpus São Carlos, 2015-09-24)
Lead (Pb) is a heavy metal widely distributed in the environment, but it does not have any physiological role in the body. Due to its widespread use in the industry, it provides direct contamination of occupationally exposed ...
