1. Rapid and Automatic Classification of Tobacco Leaves Using a Hand-Held DLP-Based NIR Spectroscopy Device
A hand-held near infrared (NIR) spectroscopy device is much more convenient than a traditional desktop NIR instrument. Thus, it is more suitable for the practical application. An automatic and rapid tool for grading tobacco leaves on the spot using a hand-held digital light processing (DLP)-based NIR spectroscopy device is proposed in this paper. Firstly, th

2. Robust pulmonary segmentation for chest radiography, combining enhancement, adaptive morphology and innovative active contours
Abstract Introduction Statistical data reveal that approximately 140 million radiological exams are performed annually in Brazil. These exams are designed to detect and to analyze fractures, caused by different types of trauma; as well as, to diagnose pathologies such as pulmonary diseases. For better visualization of those lesions or abnormalities, method

3. A gis-based tool for estimating soil loss in agricultural river basins
Abstract Soil erosion is a major problem observed in terrestrial ecosystems. Monitoring and identifying potential areas for erosion becomes extremely important for the better management of these areas. The main aim of this study was to develop a Geographic Information System script tool based on the universal soil loss equation (USLE), which calculates soil

4. Anotação automática de imagens utilizando regras de associação / Automatic image annotation using associative rules
Com os avanços tecnológicos, grandes coleções de imagens são geradas, manipuladas e armazenadas em bancos de dados. Dado o grande tamanho destes bancos, verifica-se a necessidade de se criar ferramentas para gerenciá-los de forma eficiente e eficaz. Uma das tarefas mais demandadas deste gerenciamento é a recuperação das imagens, e uma forma de fazê

5. Avaliação de algoritmos e modelos digitais de elevação para extração automática da drenagem / Automatic drainage network extraction using digital elevation models
This work is an evaluation of automatic processes for drainage extraction from Digital Elevation Models (DEM), as related to different data sources, terrain types, algorithms and operation parameters. SRTM, Topodata and GDEM data of four (4) watersheds with distinct geomorphometries were processed through six (6) different flow algorithms (D8, Rho8, Dinf, Mf

6. Contribuições para a análise de sinais neuronais e biomédicos
Following the new tendency of interdisciplinarity of modern science, a new field called neuroengineering has come to light in the last decades. After 2000, scientific journals and conferences all around the world have been created on this theme. The present work comprises three different subareas related to neuroengineering and electrical engineering: neural

7. Segmentação das áreas isquêmicas no acidente vascular cerebral utilizando imagens de tomografia computadorizada de perfusão / Segmentation of ischemic areas in stroke using perfusion computed tomography images
The techniques of digital image processing have been widely applied to medical imaging. One of the benefits brought about by these tools is to provide measurements of parameters that are difficult to estimate and likely to bias the physician. This study aimed to develop semi-automatic software of segmentation of the ischemic areas, core and penumbra in strok

8. Benefícios sociais e ambientais do coprocessamento de pneus inservíveis: estudo de caso na cidade de João Pessoa-PB
The useless tire is a residue that must be managed correctly until its final disposal as well as its collection and storage must be done adequately. Therefore, if it is inadequately disposed of, it can cause damages to the environment and to public health. In March 2005 the city of João Pessoa, initiated a program called Programa Nordeste Rodando Limpo - No

9. Contribuições à verificação funcional ajustada por cobertura para núcleos de hardware de comunicação e multimídia. / Contribuitions to coverage-driven verification of communication and multimedia IP-cores.
Making functional verification more efficient in terms of computational and time resources is mandatory in order to maintain the evolution of digital systems. Coverage driven verification is one of the recently used alternatives for speeding up the execution of testbenches. Many approaches have been successfully applied to the functional verification of core

10. Linguagens de domínio específico e sensores baseados em modelos biológicos de computação
A Domain Specific Language is a specification language dedicated to a particular domain, representation technique, or solution searching method. On the other hand, a general-purpose programming language is a language designed with the goal of emulating Lambda Calculus or Turing Machine. Since general-purpose languages must accept any algorithm that can be ex

11. Method for automatic detection of wheezing in lung sounds
The present report describes the development of a technique for automatic wheezing recognition in digitally recorded lung sounds. This method is based on the extraction and processing of spectral information from the respiratory cycle and the use of these data for user feedback and automatic recognition. The respiratory cycle is first pre-processed, in order
