1. Experimental Study of Fatigue Crack Behavior of Rib-To-Rib Butt Welded Connections in Orthotropic Steel Decks
Abstract Rib-to-rib (RR) butt welded connections are one of the most sensitive locations for encountering fatigue failure in orthotropic steel decks (OSDs), and numerous fatigue cracks arising from these areas have been identified in existing OSD bridges. Due to dynamic factors in their service life bridges with an orthotropic steel deck (OSD) are prone to f

2. Estratégias com garantia de estabilidade para a integração de controle preditivo e otimização em tempo real. / Strategies with guarantee of stability for the integration of model predictive control and real time optimization
The aim of this Thesis is the development of predictive controllers (MPC) with guarantee of stability and that are part of a control structure where Real Time Optimization (RTO) is present and produces optimizing targets for the predictive controller. The approaches of two and three-layer are considered. Three different strategies are presented: the first st

3. Posicionamento de sensores/atuadores e escolha de funções de ponderação no controle H-infinito de vibrações / Placement of sensors/actuators and selection of weighting functions in H-infinity control of vibrations
In this work it was used the H infinite control to atenuate vibrations in mechanical structures. Linear matrix inequalities are used to find the optimal controller. Sensors and actuators are incorporated into the project. To determine the best place to allocate them in the structure two methods are used: the first is based on the highest closed-loop H infini

4. Nonlocal continuum mechanics formulation for axial, flexural, shear and contraction coupled wave propagation in single walled carbon nanotubes
This paper presents the effect of nonlocal scaling parameter on the coupled i.e., axial, flexural, shear and contraction, wave propagation in single-walled carbon nanotubes (SWCNTs). The axial and transverse motion of SWCNT is modeled based on first order shear deformation theory (FSDT) and thickness contraction. The governing equations are derived based on

5. First principle calculation of potential and multi-channel transport in Fe/MgO/Fe hetero-junction
In this work we studied the behavior of multi-channel tunneling through a realistic Fe/MgO/Fe hetero-junction ab initio potential. For this purpose we obtained Fe/MgO/Fe(001) hetero-junction effective potentials using the full potential-linear augmented plane wave WIEN2k code together with the generalized gradient approximation for the exchange-correlation p

6. A RESISTÊNCIA À MÍSTICA EM EMMANUEL LÉVINAS
The aim of this research is to investigate Emmanuel Levinass resistance toward mysticism. The Levinasian argument regarding mysticism acquires the character of a philosophical argumentation starting from the theme of subjectivity and reaching its apex within the context of the reflection about language and metaphysical desire. The originality of the discussi

7. THE MYSTERIES OF CARANDIRU: PRISON, MASSACRE AND MASS CULTURE / OS MISTÉRIOS DO CARANDIRU: CÁRCERE, MASSACRE E CULTURA DE MASSAS
The aim of this dissertation is to investigate the entertainment and its different mediatics supports, concerning the phenomenon of proliferation of narratives about The House of Detention of São Paulo, the prison called Carandiru. From October 2, 1992, the date of the massacre of 111 prisoners by the Military Police, until these days, the memory of the pen

8. Study of effects of interfaces in the propagation of the energy by optical modes in coaxial cylinders
We study the influence of the interfaces on the dispersion relation, energy and power flow of polaritons propagating in coaxial cylinders. We consider an infinite coaxial cylinder of internal and external radii designated by a and b, respectively, submitted to a magnetic dc field applied parallel to the z-axes. The presence of a magnetic field causes signifi

9. Caracterização de estruturas planares com substratos Iso/Anisotrópicos truncados através da técnica da ressonância transversa modificada
This work presents a theoretical and numerical analysis using the transverse resonance technique (TRT) and a proposed MTRT applied in the analysis of the dispersive characteristics of microstrip lines built on truncated isotropic and anisotropic dielectric substrates. The TRT uses the transmission lines model in the transversal section of the structure, allo

10. THE INFINITE IMMEDIATE MODE OF EXTENSION: AN ACCOUNT OF SPINOZA`S THEORY OF MODES / O MODO INFINITO IMEDIATO DA EXTENSÃO: UMA LEITURA DA TEORIA DOS MODOS DE ESPINOSA
Apresentamos, nesta dissertação, a teoria dos modos de Espinosa, tendo como pano de fundo a P.8 da Parte II da Ética, onde surge uma aparente ruptura na simetria entre os nexos causais dos modos infinitos e finitos dos atributos pensamento e extensão, imposta pela tese do paralelismo universal, principal tese do sistema espinosista. Esta assimetria compr

11. Gravitational clustering to all perturbative orders
We derive the time evolution of the density contrast to all orders of perturbation theory, by solving the Einstein equation for scale-invariant fluctuations. These fluctuations are represented by an infinite series in inverse powers of the radial parameter. In addition to the standard growing modes, we find infinitely many more new growing modes for open and
