1. PATH ERRORS IN SUGARCANE TRANSSHIPMENT TRAILERS
ABSTRACT The need for accuracy in sugarcane machine traffic has boosted the adoption of automatic steering systems. These have been used in tractors pulling transhipment trailers. Such sets are long and articulated, which hinders their performance and benefits due to alignments in curved and laterally sloped paths. In this sense, this study aimed to quantify

3. VECTORIAL GEOGRAPHIC DATA VISUALIZATION ON MULTI-RESOLUTION TERRAIN / VISUALIZAÇÃO DE DADOS GEOGRÁFICOS VETORIAIS SOBRE TERRENOS EM MULTI-RESOLUÇÃO
This work aims to integrate the graphical representation of vectorial data found in Geographic Information Systems (GIS) and the visualization for multi-resolution 3D terrain models. The multi-resolution approach on terrain rendering brings some difficulties on the process of rendering the vectorial data in a consistent manner, since these data, in general,

4. Mapeamento de areas de cafe no municipio de Guaxupe/MG por meio de processamento digital de imagens Landsat / Coffee crop areas mapping in mountain relief through Principals Components Analysis
The economic importance of Brazilian coffee growing in the world market is notorious and makes up significant portion of the country s foreign trade exports. Minas Gerais stands out as the core of Brazilian coffee growing, with most of the planting areas (Coffea arabica) concentrated in the south, where it is grown in small plots widely spread throughout the

5. Evaluation of digital terrain model extracted from SAR data in X-Band of SAR R-99B / Avaliação do Modelo Digital do Terreno Extraído de Dados SAR Interferométricos na Banda X do SAR R-99B
In the Brazilian territory there are several areas with no topographic mapping coverage and the existent maps are not updated due to the continuous land use and land cover changes. The Sistema de Prote¸cao da Amazonia (SIPAM) uses airplanes with synthetic aperture radar which allows to image in several conditions. This radar was designed for recoinassance t

6. Processamento e interpretação de dados 2D e 3D de GPR :aplicações no imageamento de feições kársticas e estruturas de dissolução no campo de petróleo de Fazenda Belém-CE
In Fazenda Belém oil field (Potiguar Basin, Ceará State, Brazil) occur frequently sinkholes and sudden terrain collapses associated to an unconsolidated sedimentary cap covering the Jandaíra karst. This research was carried out in order to understand the mechanisms of generation of these collapses. The main tool used was Ground Penetrating Radar (GPR). Th

7. Avaliação da geometria do produto Ikonos Geo / Geometric evaluation of Ikonos Geo product
Geometric correction of satellite images is relevant to cartographic applications and to integrate these images in geographic information systems. Image correction consists in the distortion elimination, caused by the sensor and by the observed object, through models of image geometry and ancillary information such as digital terrain model and control points

8. Desktop virtual reality in the enhancement of digital elevation models
The topographic representation of a terrain may be modeled through a digital elevation model. They may contain several errors, which cause uncertainty about the reliability of the data. Realiable use of elevation data requires that uncertainty be identified and removed. However, a critical problem is the fact that these errors can be caused by many different

9. Uso de imagens Radarsat-1 para fins de mapeamento de uso da terra e cobertura do solo em ambiente tropical úmido urbano: o caso de Manaus, Estado do Amazonas. / Use of radarsat-1 data in the identification of targets related to land use and land cover in urban humid tropical region: the case of Manaus, state of the Amazon, Brazil
The use of remote sensing data acquired through Synthetic Aperture Radar has been a recent common trend for land use and land cover mapping purposes. The information derived from this kind of data has been applied to distinct related application fields, such as: urban pattern analysis and mapping, settlements identification, urban change detection and even m

10. Caracterização espectral e identificação de áreas afetadas pela seca de ponteiros do eucalipto do Vale do Rio Doce (SPEVRD) com ênfase em dados orbitais TM/Landsat / Spectral characterization and identification of effected areas of eucalyptus dyeback in the Rio Doce Valley (SPEVRD)with emphasis on orbital TM/Landsat data
A remote sensing methodology was applied to spectrally characterize euçalyptus dyeback in the Rio Doce Valley (SPEVRD), Minas Gerais State. Spectroradiometric data, 35mm color and color infrared aerial photography and TM/LANDSAT data were used to that characterization. Significant spectral differences between healthy and damaged samples were verified throug

12. Extent of possible rehabilitation of service personnel with ischaemic heart disease
Sixty unselected survivors from ischaemic heart disease, all male service personnel, were treated, within 1 to 6 months of recovery from the acute episode, by promotion of physical activity, correction of coronary risk factors, and routine use of nicoumalone and prenylamine lactate. The results showed that this approach was conducive to more rewarding rehabi
