1. Brain tissue segmentation using q-entropy in multiple sclerosis magnetic resonance images
The loss of brain volume has been used as a marker of tissue destruction and can be used as an index of the progression of neurodegenerative diseases, such as multiple sclerosis. In the present study, we tested a new method for tissue segmentation based on pixel intensity threshold using generalized Tsallis entropy to determine a statistical segmentation par

2. THERMODYNAMIC NONEXTENSIVITY, DISCRETE SCALE INVARIANCE AND ELASTOPLASTICITY: A STUDY OF A SELF-ORGANIZED CRITICAL GEOMECHANICAL NUMERICAL MODEL / NÃO-EXTENSIVIDADE TERMODINÂMICA, INVARIÂNCIA DISCRETA DE ESCALA E ELASTO-PLASTICIDADE: ESTUDO NUMÉRICO DE UM MODELO GEOMECÂNICO AUTO-ORGANIZADO CRITICAMENTE
This thesis aims at applying new concepts from solid state physics and statistical mechanics - chaos theory and fractal geometry - to the study of nonlinear dynamic systems. More precisely, it deals with a two-dimensional continuum elastoplastic Mohr-Coulomb model, commonly used to simulate pressure-sensitive materials (e.g., soils, rocks and concrete) subje

3. Metodologia de inspeção visual utilizando limiar("Threshold") entrópico com aplicações na classificação de placas de madeira / Methodology for visual inspection using entropic threshold with aplications in wooden board classification
The objective of this work was to develop a dedicated computer vision method for the classification of wooden plates used in pencil manufacturing. The process here proposed was idealized looking for a low computational complexity methodology that could be accomplished in VLSI, as for instance using Systolic Computer Architectures made of logic arrays. The pe
