Scaling properties of the fermi-ulam accelerator model
(2006-10-30)
The chaotic low energy region (chaotic sea) of the Fermi-Ulam accelerator model is discussed within a scaling framework near the integrable to non-integrable transition. Scaling results for the average quantities (velocity, ...
Cauchy-Stieltjes Integral on Time Scales in Banach Spaces and Hysteresis Operators
(Amer Inst Physics, 2012-01-01)
The play operator has a fundamental importance in the theory of hysteresis. It was studied in various settings as shown by P. Krejci and Ph. Laurencot in 2002. In that work it was considered the Young integral in the frame ...
A scale-space approach for multiscale shape analysis
(2018-01-01)
Currently, given the widespread of computers through society, the task of recognizing visual patterns is being more and more automated, in particular to treat the large and growing amount of digital images available. Two ...
Linear Integral Equations with Discontinuous Kernels and the Representation of Operators on Regulated Functions on Time Scales
(Springer, 2013-01-01)
We present here the linear Cauchy-Stieltjes integral on regulated functions with values in Banach spaces on time scales and represent a linear operator on the space of the regulated functions by means of an appropriate ...
Universality and Scaling Limit of Weakly-Bound Tetramers
(American Institute of Physics (AIP), 2012-01-01)
The occurrence of a new limit cycle in few-body physics, expressing a universal scaling function relating the binding energies of two successive tetramer states, is revealed by considering a renormalized zero-range two-body ...
StructMatrix: large-scale visualization of graphs by means of structure detection and dense matrices
(Institute of Electrical and Electronics Engineers – IEEEAtlantic City, 2015-11)
Given a large-scale graph with millions of nodes and edges, how to reveal macro patterns of interest, like cliques, bi-partite cores, stars, and chains? Furthermore, how to visualize such patterns altogether getting insights ...
Plant Species Identification Using Multi-scale Fractal Dimension Applied to Images of Adaxial Surface Epidermis
(Springer, 2009-01-01)
This paper presents the study of computational methods applied to histological texture analysis in order to identify plant species, a very difficult task due to the great similarity among sortie species and presence of ...
When small is different: The case of membranes inside tubes
(2013-01-01)
Recently, classical elasticity theory for thin sheets was used to demonstrate the existence of a universal structural behavior describing the confinement of sheets inside cylindrical tubes. However, this kind of formalism ...
Ordinary fractional differential equations are in fact usual entire ordinary differential equations on time scales
(Amer Inst Physics, 2014-01-01)
Despite the huge number of works considering fractional derivatives or derivatives on time scales some basic facts remain to be evaluated. Here we will be showing that the fractional derivative of monomials is in fact an ...
Scaling in few-body nuclear physics
(World Scientific Publ Co Pte Ltd, 2007-01-01)
The nuclear matter calculations with realistic nucleon-nucleon potentials present a general scaling between the nucleon-nucleus binding energy, the corresponding saturation density, and the triton binding energy. The ...
