1. EFFECT OF THE DOWNWASH FLOW FIELD OF A SINGLE-ROTOR UAV ON DROPLET VELOCITY IN SUGARCANE PLANT PROTECTION
ABSTRACT Protecting against the main sugarcane diseases and insect pests requires good control at the base of the plant; therefore, higher droplet penetration is required during plant protection. The objectives of this research were to explore the movement mechanism of droplets in a sugarcane protection operation using a single-rotor unmanned aerial vehicle

2. Road detection over informal settlements in a suburban area of Sao Paulo city by using high resolution satellite image and a object-based classification approach. / Detecção da malha viária na periferia urbana de São Paulo utilizando imagens de alta resolução espacial e classificação orientada a objetos.
Uncontrolled sprawl occurring in large cities of developing countries requires intensive mapping efforts to update geodatabases. The intense urbanization process experienced since the 70s in Sao Paulo city illustrates very well the reported scenario. Despite aerial data and, more recent, high spatial resolution satellite data which have been employed as basi

3. Avaliação de modelos de regressão espacial para análise de cenários do Transporte Rodoviário
The Road Freight Transportation (RFT) currently presents itself as one of the most used ways of transportation in Brazil, representing 61.1% of the transportation matrix, against 20.7% of railroad, 13.6% of the river-way, 4.2% of duct-way and 0.4% of the aerial. The possibility of delivery at the door of the purchaser, as well as the easiness of loading and

4. Aircrafts position forecast model to use in surveillance systems of aerial space. / Modelo de previsão de posição de aeronaves para uso em sistemas de vigilância do espaço aéreo.
Esta pesquisa apresenta uma contribuição para a avaliação do problema de previsão de posição futura de aeronaves dentro da aviação brasileira. O uso dessas previsões é muito importante para os sistemas de vigilância do espaço aéreo, sobretudo para a detecção de conflitos entre aeronaves. O problema é estudado para vôos em rota, considerando
