Applications of Distributed-Order Fractional Operators: A Review [PDF]

open access: yesEntropy, 2021
Distributed-order fractional calculus (DOFC) is a rapidly emerging branch of the broader area of fractional calculus that has important and far-reaching applications for the modeling of complex systems. DOFC generalizes the intrinsic multiscale nature of

General Fractional Calculus Operators of Distributed Order

open access: yesAxioms, 2023
In this paper, two types of general fractional derivatives of distributed order and a corresponding fractional integral of distributed type are defined, and their basic properties are investigated.

Stability Analysis of Distributed Order Fractional Chen System [PDF]

open access: yesThe Scientific World Journal, 2013
We first investigate sufficient and necessary conditions of stability of nonlinear distributed order fractional system and then we generalize the integer-order Chen system into the distributed order fractional domain.

Pontryagin Maximum Principle for Distributed-Order Fractional Systems [PDF]

open access: yesMathematics, 2021
We consider distributed-order non-local fractional optimal control problems with controls taking values on a closed set and prove a strong necessary optimality condition of Pontryagin type.

Stability Analysis on Nabla Discrete Distributed-Order Dynamical System

open access: yesFractal and Fractional, 2022
This paper addresses the problems of the stability of a nabla discrete distributed-order dynamical system (NDDS). Firstly, based on a proposed generalized definition of discrete integral, some related definitions of nabla discrete distributed-order ...

Haar wavelet method for solution of distributed order time-fractional differential equations

open access: yesAlexandria Engineering Journal, 2021
This manuscript is related to compute approximate solutions for a class of fractional distributed order differential equations (FDODEs). The corresponding derivative of fractional order is taken in Caputo sense.

A generalised distributed‐order Maxwell model [PDF]

open access: yesMathematical methods in the applied sciences, 2022
In this work, we present a generalised viscoelastic model using distributed‐order derivatives. The model consists of two distributed‐order elements (distributed springpots) connected in series, as in the Maxwell model.

A composite collocation method based on the fractional Chelyshkov wavelets for distributed-order fractional mobile-immobile advection-dispersion equation

open access: yesMathematical Modelling and Analysis, 2022
In this study, an accurate and efficient composite collocation method based on the fractional order Chelyshkov wavelets is proposed for obtaining approximate solution of distributed-order fractional mobile-immobile advection-dispersion equation with ...

Vibration Systems with Fractional-Order and Distributed-Order Derivatives Characterizing Viscoinertia

open access: yesFractal and Fractional, 2021
We considered forced harmonic vibration systems with the Liouville–Weyl fractional derivative where the order is between 1 and 2 and with a distributed-order derivative where the Liouville–Weyl fractional derivatives are integrated on the interval [1, 2]

Multiscale Nonlocal Elasticity: A Distributed Order Fractional Formulation [PDF]

open access: yesInternational Journal of Mechanical Sciences, 2021
This study presents a generalized multiscale nonlocal elasticity theory that leverages distributed order fractional calculus to accurately capture coexisting multiscale and nonlocal effects within a macroscopic continuum. The nonlocal multiscale behavior
