On distance sets, box-counting and Ahlfors regular sets
(Alliance of Diamond Open Access Journals, 2017-05)
We obtain box-counting estimates for the pinned distance sets of (dense subsets of) planar discrete Ahlfors-regular sets of exponent s > 1. As a corollary, we improve upon a recent result of Orponen, by showing that if A ...
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 ...
Improved bounds for the dimensions of planar distance sets
(European Mathematical Society, 2020-12)
We obtain new lower bounds on the Hausdorff dimension of distance sets and pinned distance sets of planar Borel sets of dimension slightly larger than 1, improving recent estimates of Keleti and Shmerkin, and of Liu in ...
Characterization of texture in image of skin lesions by support vector machine
(2012-11-19)
Due to the increased incidence of skin cancer, computational methods based on intelligent approaches have been developed to aid dermatologists in the diagnosis of skin lesions. This paper proposes a method to classify ...

Finite-dimensional global attractors in Banach spaces
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
We provide bounds on the upper box-counting dimension of negatively invariant subsets of Banach spaces, a problem that is easily reduced to covering the image of the unit ball under a linear map by a collection of balls ...
Box Counting Dimension of Red Blood Cells Samples when Filtered with Wavelet Transform
(Asociación Argentina de Mecánica Computacional, 2017-11)
Automatic recognizing of different populations of several millions of red blood cells (RBCs) is a useful tool in Hematology and Clinical Diagnosis. In this work we studied samples of several millions of RBCs: on one hand ...
