Chaotic dynamics of a nonlinear electronic converter
(2008)"The nonlinear electronic converter used by Rulkov and collaborators [Rulkov et al., 2001], which is the core of their chaotic oscillator, is modeled and simulated numerically by means of an appropriate direct relationship ... -
Perceptual security of encrypted images based on wavelet scaling analysis
(2016)"The scaling behavior of the pixel fluctuations of encrypted images is evaluated by using the detrended fluctuation analysis based on wavelets, a modern technique that has been successfully used recently for a wide range ... -
Scaling analyses based on wavelet transforms for the Talbot effect
(2013)"The fractal properties of the transverse Talbot images are analysed with two well-known scaling methods, the wavelet transform modulus maxima (WTMM) and the wavelet transform multifractal detrended fluctuation anal- ysis ... -
Talbot effect for dispersion in linear optical fibers and a wavelet approach
(2006)"We shortly recall the mathematical and physical aspects of Talbot’s self-imaging effect occurring in near-field diffraction. In the rational paraxial approximation, the Talbot images are formed at distances z = p/q, where p ... -
Wavelet multifractal detrended fluctuation analysis of encryption and decryption matrices
(2013)"In this paper, we study in detail the multifractal features of the main matrices of an encryption system based on a rule-90 cellular automaton. For this purpose we consider the scaling method known as the wavelet transform ...
