Aplicação do método box counting para a estimativa da dimensão fractal de figuras planas digitalizadas
(Universidade Federal de Santa MariaCentro de Ciências Rurais, 2007-12-17)
Many forms in the nature can not be explained in the molds of the conventional
mathematics. In order to fulfill this need scientists have developed the fractal geometry. The science of Fractals, since its origin, is the ...
WHAT ARE FRACTALS: A CONCEPTUAL ANALYSIS OF ITS CHARACTERISTICS FROM BRAZILIAN RESEARCHO QUE SÃO FRACTAIS: UMA ANÁLISE CONCEITUAL DE SUAS CARACTERÍSTICAS A PARTIR DE PESQUISAS BRASILEIRAS
(Universidade Federal de Mato Grosso (UFMT), 2020)
Characterization of nanostructured material images using fractal descriptors
(ElsevierAmsterdam, 2013-04)
This work presents a methodology to the morphology analysis and characterization of nanostructured material images acquired from FEG-SEM (Field Emission Gun-Scanning Electron Microscopy) technique. The metrics were extracted ...
Análise de estruturas inspiradas em fractais aplicadas em antenas e superfícies seletivas de frequência
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E DE COMPUTAÇÃO, 2018-07-13)
The development of new fractal-based structures applied to planar technology has
motivated many researchers around the world, who are very interested in the design of
compact, stable, efficient, and low cost microwave ...
A combined experimental and numerical approach to the assessment of floc settling velocity using fractal geometry
(2020-03-01)
Sedimentation processes are fundamental to solids/liquid separation in water and wastewater treatment, and therefore a robust understanding of the settlement characteristics of mass fractal aggregates (flocs) formed in the ...
Caracterização da rugosidade em superfícies nitretadas a plasma da liga Ti6Al4V
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2010-01-07)
This paper deals with the characterization of topographic changes occurred on surfaces of plasma nitrided Ti6Al4V-ELI alloy. Surface roughness is an important parameter of materials used in situations involving friction, ...
Fractal dimension of diffusion-limited aggregation clusters grown on spherical surfaces
(American Physical Society, 2021-01)
In this work we study the fractal properties of diffusion-limited aggregation (DLA) clusters grown on spherical surfaces. Diffusion-limited aggregation clusters, or DLA trees, are highly branched fractal clusters formed ...
Mass fractal characteristics of silica sonogels as determined by small-angle x-ray scattering and nitrogen adsorption
(American Physical Soc, 2005-01-01)
A sample series of silica sonogels was prepared using different water-tetraethoxysilane molar ratio (r(w)) in the gelation step of the process in order to obtain aerogels with different bulk densities after the supercritical ...
