13. Application of H∞ theory to a 6 DOF flight simulator motion base
The purpose of this study is to apply inverse dynamics control for a six degree of freedom flight simulator motion system. Imperfect compensation of the inverse dynamic control is intentionally introduced in order to simplify the implementation of this approach. The control strategy is applied in the outer loop of the inverse dynamic control to counteract th

14. Structure and dynamics of poly(9,9-dioctylfluoren-2,7-co-benzothiadiazole) (F8BT) and correlations with its electrical properties / Estrutura e dinâmica molecular do poly (9,9-dioctylfluoren-2,7-diyl-co-benzothiadiazole) (F8BT) e correlações com suas propriedades elétricas.
The PHD project has two main goals. The first one is specifically related to investigations on molecular dynamics, structural conformations and packing of polyfluorene-based polymers. For this purpose, Wide Angle X-Ray Diffraction (WAXD), Solid-State Nuclear Magnetic Resonance (NMR) and Dynamical-Mechanical Thermal Analysis (DMTA) are being used as the main

15. A CFD-based analysis of the 14-Bis aircraft aerodynamics and stability
Abstract The work reported in the present paper was performed to honor the centennial of the flight by Alberto Santos Dumont with his 14-Bis aircraft. The paper describes results for a computational fluid dynamics (CFD) analysis of the 14-Bis aircraft aerodynamics and flight stability. The 14-Bis aircraft geometry was generated from historical sources and ob

16. A interpretação de Martin Heidegger acerca do sagrado no poema Como quando em dia de feriado de Friederich Hölderlin
The object of research in this thesis is the interpretation of the holy proposed by German philosopher Martin Heidegger (1889 1976) on the basis of his reading of Friedrich Hölderlins (1770 1843) poem Wie wenn am Feiertage... (As on a holiday). Heideggers turning to Hölderlins poetry takes place due to a necessity intrinsic to the path of his own thinking.

17. An approach to design feedback controllers for flight control systems employing the concepts of gain scheduling and optimization.
The role of feedback in the design of aircraft stability and control is becoming increasingly important. The basic reason driving this trend is the necessity to cope with a growing number of more stringent requirements, which are sometimes conflicting. This work presents a design methodology applicable to flight control laws, which can be either a control an

18. Das imagens identitarias da pedagogia ao oficio de pedagogo : traçados nomades / From the identitary images in pedagogy to the work of the work of the tachers : nomadic traces
The object of this study is to relocate the problematic of teacher/pedagogue and Pedagogy identity in the contemporary times, according to the latest analytical basis. Na investigative, reflexive, conceptual and immanent methodology will be used, based on the philosophy of Gilles Deleuze and Félix Guattari, and it does not disconsider the practical nature o

19. Trajectory planning of jumping over obstacles for hopping robot
Trajectory planning strategy is proposed to jump over an obstacle integrated three various dynamics in one-legged multi-joint hopping robot. A concept of inertia matching ellipsoid and directional manipulability are extended to optimize take-off postures. Optimized results have been used to plan hopping trajectory. Aimed at the sensitivity of motion trajecto

20. Estudo da fluidodinâmica e da secagem de um secador rotatório da indústria de fertilizantes
The dimensioning, the modeling and the simulation of the rotary dryers constitutes a big challenge. The drying involves mass and heat transfer, and fluid dynamics processes of the most different forms. Great part of the dryers projects are done according to empiricism and based on the experience of engineers and on the scale-up of prototypes. The purpose of

21. Abrasão, desgaste e atrito sob deslizamento de recobrimentos preparados por aspersão térmica a partir de PET pós-consumo
This work intends to contribute to the development of polymer coatings by combustion thermal spraying of recycled poly(ethylene terephthalate) PET for the improvement of the tribological behavior of carbon steel piping. Coatings with high wear resistance may reduce corrosion, the formation of organic and inorganic deposits, and the friction of the transporte

22. Investigação Experimental da Adição de Energia por Laser em Escoamento Hipersônico de Baixa Densidade
The possibility of reducing the aerodynamic drag and heating of a hypersonic vehicle by addition energy to the air ahead of it is an attractive idea directed toward the hypersonic field. (Mach>5) and can be realized by laser induced plasma generation. In this context, this work presents original results in the experimental investigation of the energy addi

23. The dynamics of dengue virus serotype 3 introduction and dispersion in the state of Bahia, Brazil
By 2002, dengue virus serotype 1 (DENV-1) and DENV-2 had circulated for more than a decade in Brazil. In 2002, the introduction of DENV-3 in the state of Bahia produced a massive epidemic and the first cases of dengue hemorrhagic fever. Based on the standardized frequency, timing and location of viral isolations by the state's Central Laboratory, DENV-3 prob

24. Non linear dynamics and control of an aircraft in longitudinal flight / Dinamica não linear e controle de uma aeronave em voo longitudinal
Neste trabalho analisou-se a dinâmica não linear de uma aeronave em vôo longitudinal. Efetuou-se a análise do comportamento bifurcacional da aeronave F-8 Cruzader. Na análise bifurcacional foi estudado o comportamento topológico desta aeronave tomando-se dois parâmetros de controle: a deflexão do profundor e a alteração da massa da referida aer
