14. The integration of GPS, vegetation mapping and GIS in ecological and behavioural studies
Global Positioning System (GPS) satellite navigation receivers are increasingly being used in ecological and behavioural studies to track the movements of animals in relation to the environments in which they live and forage. Concurrent recording of the animal's foraging behaviour (e.g. from jaw movement recording) allows foraging locations to be determined.

17. Modelagem ambiental de uma casa de vegetação utilizando rede de osciladores de Van Der Pol. / Greenhouse environmental modeling using Van Der Pol oscillator network.
Agricultural automation is an important area in the development of Brazilian production in recent years. Often, measurement and control of the internal conditions of greenhouses are not easy to implement at a reasonable cost. Researches in this area look for models using computational theory, foreseeing the behavior of internal variables of a greenhouse from

20. Utilização de perfis multi-temporais do NDVI/AVHRR no acompanhamento da safra de soja no oeste do Parana / Use of NDVI/AVHRR time-series profiles for soybean crop monitoring in the west of Parana, Brazil
Crop yield forecasting systems are important sources of information for helping Governrnent and private institutions in agricultural trade matters. The traditional methods of crop yield forecasting norma1ly do not provide precise estimations, due to its subjectivity. The use of Geothecnology has been studied for the development of more efficient crop yield f

21. Aplicação de logica fuzzy para estimativa de area plantada da cultura de soja utilizando imagens AVHRR-NOAA / Application of fuzzy logic for soybean crop area estimation using AVHRR-NOAA images
An early accurate estimation of agricultural crop areas, such as soybean, is fundamental for the Brazilian economy. The draining forecast and the estimation of agricultural production commercialization are strategic to Brazil, since they are directly related to planning, costs and price. Recent technological progress of data acquisition from orbital remote s

24. Estimativa de áreas agrícolas por meio de técnica de sensoriamento remoto, geoprocessamento e amostragem / Crop area estimation using remote sensing, geoprocessing and sample techniques
Efficient estimates of agricultural production require practical and rapid methods for its accomplishment. In this context, the use of computer to speed up the involved processes during the estimates is important. Thus, the present work comes to contribute with the automation of the procedures for stratification and allocation of samples to estimate the cult
