1. A Hierarchical and Prioritized Framework in Coordinated Maneuver of Multiple Uavs Based on Guidance Regulator
ABSTRACT The structure of mission management and maneuver planning for multiple UAVs in close formation flight is investigated. This article provides a distributed and priority-based platform of guidance and control model to meet requirements for each coordinated maneuver. To accomplish the coordinated maneuvers of multiple UAVs, some levels of hierarchy fro

2. In-flight collision avoidance controller based only on OS4 embedded sensors
The major goal of this research was the development and implementation of a control system able to avoid collisions during the flight for a mini-quadrotor helicopter, based only on its embedded sensors without changing the environment. However, it is important to highlight that the design aspects must be seriously considered in order to overcome hardware lim

3. Sistema anti-colisão de alerta ao motorista com o uso de estímulo auditivo e háptico. / Collision-avoidance system using auditory and haptic feedback.
Neste trabalho, é desenvolvido um estudo sobre o uso de alertas auditivos e hápticos dentro do ambiente veicular. É proposto um sistema de assistência ao motorista para alertá-lo de que uma colisão lateral com outros veículos pode ser iminente, quando a observação do espelho retrovisor é insuficiente ou o motorista está desatento. O sistema é com

4. O princípio da proporcionalidade, o planejamento tributário e a norma geral antielisiva / The general anti-avoidance provison, tax planing and the principle of proportionality.
The present paper addresses the principle of proportionality, tax planning and the general anti-avoidance provision. Firstly, the historical evolution of legal thinking will be addressed, based on the propositions established in the field of the general interpretation theory, through the theoretical frameworks of the jurisprudence of concepts, the jurisprude

5. Propagação de incertezas na navegação de veículos aeroespaciais visando minimizar o risco de colisão / Propagation of uncertainties in the navigation of aerospace vehicles to minimize or maximize the collision risk
Neste trabalho realizou-se o estudo de diversas idéias relacionadas ao problema do cálculo de probabilidade de colisão de satélites. Com base nessas idéias, foi realizada a simulação de métodos para propagação de incertezas na navegação de veículos aeroespaciais e determinação de risco de colisões, visando sua minimização ou maximização.

6. Risk analysis of the airborne time-based spacing operation through a stochastically and dinamiclly coloured Petri net model. / Análise de risco da operação de espaçamento temporal aerotransportado por meio de um modelo em rede de Petri estocástica e dinamicamente colorida.
The safety in the airspace can considerably increase with the use of airborne spacing and separation operations. Under this paradigm, the task of maintaining a safe distance between aircraft is delegated to the pilots, which will be supported by the Airborne Separation Assistance System (ASAS). With this system, which is still in experimental phase, pilots b

7. Arquitetura híbrida inteligente para navegação autônoma de robôs / Intelligent hybrid architecture for robot autonomous navigation
This project consists in a autonomous navigation system based on modular neuro-fuzzy networks that is able to guide the robot in unknown environments from a initial point to the goal. Initially, the system is not able to navigate, but after a trial and error period and some collisions, it improves in guiding the robot to the goal efficiently. A intelligent h

8. SMART WAVELENGTH ROUTING ASSIGNMENT ON WDM NETWORKS BY FUNCTIONALITY ON PHYSICAL LAYER / ROTEAMENTO INTELIGENTE EM REDES WDM POR FUNCIONALIDADE NA CAMADA FÍSICA / RUTEAMIENTO INTELIGENTE EN REDES WDM POR FUNCIONALIDAD EN LA CAPA FÍSICA
In conventional optical networks, optoelectronic conversions are needed in each node for the sake of a proper packet routing. Simultaneously, intensive managing resources should be allocated to accomplish the routing task. The correct introduction of intelligence and functionality within the network physical layer may lead to some advantages over conventiona
