13. Análise multi-temporal de cenas do satélite quickbird usando um novo paradigma de classificação de imagens e inferências espaciais. Estudo de caso: Belo Horizonte, MG / Multi-temporal analysis of quickbird images using a new classification paradigm and spatial inferences. A case study: Belo Horizonte - MG, Brazil
Due to the strong urbanization process occurring in Brazil and of population increase in cities, and consequently to serious impacts on environment, there is a growing need to develop methodologies and technologies which allow to monitor, analyze and to make an intervention at the urban expansion. Belo Horizonte (State Capital of Minas Gerais) is a highly co

14. 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

15. 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

16. Correcao geometrica de imagens SPOT com uso de um modelo digital de elevacao / Geometric correction of SPOT imagery with the use of a digital elevation model
This work describes a theoretical and pratical methodology for geometric correction of satellite imagery including effects of relief. The methodology present here is applicable over the unfavourable situations, such as images obtained in lateral view with large inclination angle and pronounced height differences. The images already corrected must be supperpo

22. Accuracy and precision of the TAS analyser for near-patient INR testing by non-pathology staff in the community.
AIMS: To assess the accuracy and precision of INR measurement by trained practice and district nursing staff using the Thrombolytic Assessment System (TAS) analyser. METHODS: Seventeen nurses from four practices were trained to measure INR using the TAS analyser on citrated capillary blood samples. Quality control (QC) consisted of: daily internal QC using n
