Solutions of the perturbed KdV equation for convecting fluids by factorizations
(2010)"In this paper, we obtain some new explicit travelling wave solutions of the perturbed KdV equation through recent factorization techniques that can be performed when the coefficients of the equation fulfill a certain ... -
Spectral parameter power series representation for Hill´s discriminant
(Elsevier, 2010)"We establish a series representation of the Hill discriminant based on the spectral parameter power series (SPPS) recently introduced by V. Kravchenko. We also show the invariance of the Hill discriminant under a Darboux ... -
Supersymmetric free-damped oscillators: adaptive observer estimation of the Riccati parameter
(2006)"A supersymmetric class of free damped oscillators with three parameters has been obtained in 1998 by Rosu and Reyes through the factorization of the Newton equation. The supple-mentary parameter is the integration constant ... -
Supersymmetric methods in the traveling variable: inside neurons and at the brain scale
(2008)"We apply the mathematical technique of factorization of differential operators to two different problems. First we review our results related to the supersymmetry of the Montroll kinks moving onto the microtubule walls ... -
Supersymmetry of FRW barotropic cosmologies
(2006)"Barotropic FRW cosmologies are presented from the standpoint of nonrelativis-tic supersymmetry. First, we reduce the barotropic FRW system of diferential equations to simple harmonic oscillator diferential equations. ... -
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 ... -
The Hurst exponents of Nitzschia sp. diatom trajectories observed by light microscopy
(Elsevier, 2015)"We present the results of an experiment with light microscopy performed to capture the trajectories of live Nitzschia sp. diatoms. The time series corresponding to the motility of this kind of cells along ninety-five ... -
Travelling-wave solutions for Korteweg-de Vries-Burgers equations through factorizations
(2006)"Travelling-wave solutions of the standard and compound form of Korteweg-de Vries-Burgers equations are found using factorizations of the correspond-ing reduced ordinary diferential equations. The procedure leads to solutions ... -
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 ... -
Words for nobel prizes
(2003)"We present the statistics of the significant nouns and adjectives of social impact figuring in the nominations of the Nobel prizes in Physics and Chemistry over the period of the awards from 1901 to 2001."
