1. Segmenting mammographic microcalcifications using a semi-automatic procedure based on Otsu's method and morphological filters
INTRODUCTION: Breast cancer has the second highest world's incidence rate, according to the Brazilian National Cancer Institute (INCa). Clinical examination and mammography are the best methods for early diagnosis. Computer-aided detection (CADe) and computer-aided diagnosis (CADx) systems are developed to improve mammographic diagnosis. Basically, CADx syst

2. Manual and semi-automatic quantification of in vivo ¹H-MRS data for the classification of human primary brain tumors
In vivo proton magnetic resonance spectroscopy (¹H-MRS) is a technique capable of assessing biochemical content and pathways in normal and pathological tissue. In the brain, ¹H-MRS complements the information given by magnetic resonance images. The main goal of the present study was to assess the accuracy of ¹H-MRS for the classification of brain tumors i

3. Mapeamento de cobertura vegetal do bioma Cerrado: estratégias e resultados.
ABSTRACT: Mapping Cerrado's vegetation cover is difficult because of its geographical extemt (~ 204,7 million hectares), high seasonality, and high spatial and temporal dynamics of its land use activities. The objective of this study was to map the vegetation cover of the Cerrado biome in the 1:250,000 scale using Landsat satellite imageries from the year of

4. AUTOMATIC CLASSIFICATION OF SEMI-STRUCTURED DATA / CLASSIFICAÇÃO AUTOMÁTICA DE DADOS SEMI-ESTRUTURADOS
The problem of data classification goes back to the definition of taxonomies covering knowledge areas. With the advent of the Web, the amount of data available has increased several orders of magnitude, making manual data classification impossible. This dissertation proposes a method to automatically classify semi-structured data, represented by frames, with

8. Otimização e automatização do projeto de sistemas de ancoragem de plataformas semi-submersiveis
There are a few programs around the world used for determining the main aspects of the Mooring Design of Semi-submersible platforms. These programs hold a worldwide acknowledgement and their results are actually reliable. But they require many runs to get a solution that comply with the Classification Society requirements. So, the expended time to carry out
