The solution of a nonlinear diffusion equation is numerically investigated using the generalized Fourier transform method. This equation includes fractal dimensions and power-law dependence on the radial variable and on the diffusion function. The ge

The development of supersymmetric (SUSY) quantum mechanics has shown that some of the insights based on the algebraic properties of ladder operators related to the quantum mechanical harmonic oscil...

We present new connections among linear anomalous diffusion (AD), normal diffusion (ND) and the Central Limit Theorem (CLT). This is done by defining a point transformation to a new position variable, which we postulate to be Cartesian, motivated by

Accurate seismic modeling in realistic media serves as the basis of seismic full-waveform inversion and imaging. Recently, viscoacoustic seismic modeling incorporating attenuation effects has been performed by solving a fractional Laplacian viscoacou

Using ideas based on supersymmetric quantum mechanics, we design canonical transformations of the usual position and momentum to create generalized “Cartesian-like” positions, W, and momenta, Pw , with unit Poisson brackets. These are quantized b

The augmentation of low frequencies is an important problem for inverting seismic reflection data. Through an acoustic-scattering approach, we have characterized how the data down to zero frequency grows in importance with increasing depth and the si

A generalization of the varying weight trimmed mean (VWTM) filter is proposed for the removal of both additive and impulse noise from corrupted images by introducing the center pixel to the original VWTM filter. Unlike many traditional nonlinear filt

A simple and efficient nonlinear image filtering technique, called the dual window selective median switching (DWSMS) filter, for the removal of both additive and impulse noise from corrupted images, is proposed. Two moving concentric windows are emp
