Fractional cosine and sine transforms in relation to the fractional Fourier and Hartley transforms [PDF]

open access: yes, 2003
The fractional cosine and sine transforms - closely related to the fractional Fourier transform, which is now actively used in optics and signal processing, and to the fractional Hartley transform - are introduced and their main properties and possible ...

The Periodogram of fractional processes [PDF]

open access: yes, 2007
We analyse asymptotic properties of the discrete Fourier transform and the periodogram of time series obtained through (truncated) linear filtering of stationary processes.

Mode analysis in optics through fractional transforms [PDF]

open access: yes, 1999
The relationship between the mode content and the fractional Fourier and fractional Hankel transforms of a function is established. It is shown that the Laguerre-Gauss spectrum of a rotationally symmetric wavefront can be determined from its fractional ...

Mappings for Special Functions on Cantor Sets and Special Integral Transforms via Local Fractional Operators

open access: yesAbstract and Applied Analysis, 2013
The mappings for some special functions on Cantor sets are investigated. Meanwhile, we apply the local fractional Fourier series, Fourier transforms, and Laplace transforms to solve three local fractional differential equations, and the corresponding ...

Fourier transforming a trapped Bose-Einstein condensate by waiting a quarter of the trap period: simulation and applications [PDF]

open access: yes, 2006
We investigate the property of isotropic harmonic traps to Fourier transform a weakly interacting Bose–Einstein condensate (BEC) every quarter of a trap period.

Analysis of De-Levie’s model via modern fractional differentiations: An application to supercapacitor

open access: yesAlexandria Engineering Journal, 2019
De-Levie’s model has become an indispensable model for knowing a porous electrode because electrochemical supercapacitors provide electrical energy storage and they use nanoporous electrodes to store large amounts of charge.

A Note on Function Spaces with Fractional Fourier Transforms in Wiener-type Spaces

open access: yesDüzce Üniversitesi Bilim ve Teknoloji Dergisi, 2023
The purpose of this paper is to introduce and study a function space A_(α,w)^(B,Y) (R^d ) to be a linear space of functions h∈L_w^1 (R^d ) whose fractional Fourier transforms F_α h belong to the Wiener-type space W(B,Y)(R^d ), where w is a Beurling ...

Fractional Equations for the Scaling Limits of Lévy Walks with Position-Dependent Jump Distributions

open access: yesMathematics, 2023
Lévy walks represent important modeling tools for a variety of real-life processes. Their natural scaling limits are known to be described by the so-called material fractional derivatives.
