5. A novel antena for airborne radar : tridimensional Yagi / Um novo tipo de antena para radar aerotransportado : Yagi tridimensional
Embedded systems using Synthetic Aperture Radar (SAR), in orbital or airborne platforms, have often been used for remote sensing. When these systems are applied to vegetal cover and biomass studies, signals with frequency above 1 GHz do not properly penetrate in the vegetation. On the other hand, the use of signals with frequencies in P band (400 MHz) allows

10. Determination of Linear Approach for Parts of Not Linear Functions for Embarked Systems Using Genetic Algorithms / Determinação de aproximação linear por partes de funções não lineares para sistemas embarcados utilizando algoritmos genéticos
In several applications in electronics, the generation of nonlinear function values using low-cost embedded systems is a problem. The nonlinear functions cannot be directly implemented due to restrictions of fixed-point calculations and limited resolution that are characteristics of the architecture of the processor employed. In this work, a procedure for de

11. Posicionamento e movimentação de um robô humanóide utilizando imagens de uma câmera móvel externa
This work proposes a method to localize a simple humanoid robot, without embedded sensors, using images taken from an extern camera and image processing techniques. Once the robot is localized relative to the camera, supposing we know the position of the camera relative to the world, we can compute the position of the robot relative to the world. To make the

12. Interactive television based on insertion of hypermedia information on MPEG standard video / TV interativa baseada na inclusão de informações hipermidia em videos no padrão MPEG
The interactive TV is one of the great promises on Consumer Electronics field. However, there is no definitive standard to implement this new kind of device. For this reason, researches are conducted to develop a standard cheap, simple, and also the most functional as possible. Tracing this reasoning, this work proposes a model to insert hypermedia informati
