1. Catalisadores de Ir-Ru/Al2O3 e Ru/Al2O3 aplicados em sistemas propulsores / Ir-Ru/Al2O3 and Ru/Al2O3 catalysts used in thruster system propulsivos
Catalisadores de Ir/Al2O3, Ir-Ru/ Al2O3 e Ru/ Al2O3 com teores metálicos próximos a 30% em peso, foram preparados em vinte etapas de impregnação utilizando-se uma alumina sintetizada no LCP/INPE como suporte. Os catalisadores de Ir e Ir-Ru foram preparados a partir de soluções contendo precursores metálicos clorados pelo método de impregnação incip

2. Medida da temperatura de íons em um propulsor a plasma do tipo hall via espectroscopia óptica
Spectroscopy is one of the most used techniques concerning the study of plasma, owning particulary to the fact that it is a non-intrusive method. Others plasma diagnostic techniques with emissive probe and energy analyzers perform the desired measurement but interfere in the field configuration as well as in plasma itself provoking plasma cooling and ions re

3. Modelagem e identificação de parâmetros hidrodinâmicos de um veículo robótico submarino. / Modelling and Identification of hydrodynamic parameters of an underwater robotic vehicle.
In this work, a procedure for experimental identification of hydrodynamic coefficients of unmanned underwater vehicles is presented. At first, the development of a testbed for research on dynamics, control, and navigation of underwater vehicles is presented. This experimental platform includes: 1) a open-frame semi-autonomous unmanned underwater vehicle name

4. Dynamic positioning system of semi-submersible platform using fuzzy control
The purpose of this paper is the study of fuzzy control applied to a Dynamic Positioning System (DPS) of semi-submersible platforms. A numerical simulator program in time domain was coded using mathematical models of the floating platform dynamics and the external forces (wind, current, wave and thruster) that act on the platform. Subsequently, a fuzzy contr
