Ensaios não destrutivos aplicados à madeira serrada e estruturas : técnicas potenciais para uso no Brasil
(Universidade Federal de São Carlos, 2011-11-18)
The wood has many different characteristics, resulting, in part, of the conditions in which the tree grows. The physical conditions of the wood are also influenced by its complex internal structure, resulting in an anisotropic ...
Comportamento multicrítico no modelo de Heisenberg frustrado: transições de fases clássica e quântica
(Universidade Federal de São Carlos, 2011-09-01)
In this work we study the critical behavior of systems described by the Anysotropic- Heisenberg model of spin 1/2 with competitive interactions (J1-J2 Model) on planes, and interplane nearest-neighbor interactions. We ...
Uma caracterização homotópica do espaço de laços da suspensão de um espaço topológico
(Universidade Federal de São Carlos, 2011-03-06)
Our main goal in this dissertation is to show that the loopspace of reduced suspension of a connected CW complex X has the same type of homotopy that the free topological monoid generated by X.
Análise da percepção das comunidades escolares sobre segurança de trânsito no entorno das escolas do município de São Carlos - S.P.
(Universidade Federal de São Carlos, 2011-03-30)
The rates of traffic accidents have shown a serious public health issue. The incompatibility between the built environment of cities, the behavior of drivers, the great movement of pedestrians under unsafe conditions, ...
Efeito Aharonov-Bohm em partículas neutras
(Universidade Federal de São Carlos, 2011-03-14)
In classical Physics, the motion of an electrically charged particle is affected only by the presence of a magnetic field if the particle enters a region of space in which the field is present. Meanwhile, in quantum Physics, ...
Geometria e simetrias do emaranhamento
(Universidade Federal de São Carlos, 2011-05-20)
In the present work we present a geometric method to identify and measure the degree of entanglement of a two-qubit state. It is based on writing a map of the system state, from a non-unitary transformation. By introducing ...
Resultados de existência para as equações críticas de Klein-Gordon-Maxwell
(Universidade Federal de São Carlos, 2011-02-10)
In this work we analyze the existence of radially symmetric solutions, positive solutions as well as the existence of ground state solutions for a class of Klein-Gordon-Maxwell equations when the nonlinearity exhibits ...
Síntese assistida por microondas de LiMn2O4, caracterização e testes como catodo para dispositivos de armazenamento de energia
(Universidade Federal de São Carlos, 2011-03-02)
Lithium manganese oxide - LiMn2O4 - was produced by a microwaveassited solid state reaction. Solid mixtures containing LiOH.H2O and -MnO2 (synthesized electrolytically) underwent microwave irradiation for 3, 4 and ...
Estimativas locais para complexos elíticos
(Universidade Federal de São Carlos, 2011-06-16)
In this work, we extend some global L1 estimates proved by Bourgain-Brezis in the case of the de Rham complex on RN to the setup of local L1 estimates for elliptic complexes, namely, those associated to involutive elliptic ...
Investigação microestrutural e estudo das propriedades mecânicas da liga de alumínio AA2139 T3 e T8 soldadas por Friction Stir Welding - FSW
(Universidade Federal de São Carlos, 2011-02-17)
Aluminum alloys have low density and high corrosion resistance, and because of that this alloys are being increasingly used in aircraft industry. However, a downside of this alloys is its weldability in fusion process, ...
