Identificação de plantas por análise de textura foliar
(Sociedade Brasileira de Redes Neurais - SBRNRio de Janeiro, 2011)
A biodiversidade das espécies existentes no riquíssimo reino vegetal tornam os modelos tradicionais de taxonomia, na qual o processo de classificação é realizado manualmente, uma tarefa muito complexa e morosa. As dificuldades ...
Fractal Dimension of Dog Kidney Proximal Convoluted Tubuli Sections by Mean Box-Counting Algorithm
(Sociedad Chilena de Anatomía, 2006)
Development of a quality index method (QIM) sensory scheme and study of shelf-life of ice-stored blackspot seabream (Pagellus bogaraveo)
(Elsevier B.V., 2011-12-01)
The aim of this work was to develop a quality index method (QIM) scheme for whole ice-boxed refrigerated blackspot seabream and to perform shelf-life evaluations, using sensory analysis, GR Torrymeter measurements and ...
Microbiological vulnerability of eggs and environmental conditions in conventional and free-range housing systems
Although Brazil is currently the world’s eighth largest egg exporter, the shift of consumers towards free-range eggs may present new sanitary challenges. This study aims to evaluate the microbiological vulnerability of ...
Fractal dimension in quantifying experimental-pulmonary-hypertension-induced cardiac dysfunction in rats
Background: Right-sided heart failure has high morbidity and mortality, and may be caused by pulmonary arterial hypertension. Fractal dimension is a differentiated and innovative method used in histological evaluations ...
Closed contour fractal dimension estimation by the Fourier transform
This work proposes a novel technique for the numerical calculus of the fractal dimension of fractal objects which can be represented as a closed contour. The proposed method maps the fractal contour onto a complex signal ...
TOWARD REDUCTION OF ARTIFACTS IN FUSED IMAGES
Most fusion satellite image methodologies at pixel-level introduce false spatial details, i.e. artifacts, in the resulting fused images. In many cases, these artifacts appears because image fusion methods do not consider ...
Sets which are not tube null and intersection properties of random measures
(Oxford University Press, 2015-02)
We show that in ℝd there are purely unrectifiable sets of Hausdorff (and even box counting) dimension d - 1 which are not tube null, settling a question of Carbery, Soria and Vargas, and improving a number of results by ...
Fractal dimension applied to plant identification
(ELSEVIER SCIENCE INC, 2008)
This article discusses methods to identify plants by analysing leaf complexity based on estimating their fractal dimension. Leaves were analyzed according to the complexity of their internal and external shapes. A computational ...
Dimensão fractal na quantificação do grau de rejeição celular miocárdica pós-transplante cardíaco
(Sociedade Brasileira de Cirurgia Cardiovascular, 2011-06-01)
INTRODUÇÃO: O termo fractal é derivado do latim fractus, que significa irregular ou quebrado, considerando a estrutura observada como tendo uma dimensão não-inteira. Há muitos estudos que empregaram a Dimensão Fractal (DF) ...
