Vibration Systems with Fractional-Order and Distributed-Order Derivatives Characterizing Viscoinertia [PDF]

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]

A comparison study of steady-state vibrations with single fractional-order and distributed-order derivatives

open access: yesOpen Physics, 2017
We conduct a detailed study and comparison for the one-degree-of-freedom steady-state vibrations under harmonic driving with a single fractional-order derivative and a distributed-order derivative.

Two unconditionally stable difference schemes for time distributed-order differential equation based on Caputo–Fabrizio fractional derivative [PDF]

open access: yesAdvances in Difference Equations, 2020
We consider distributed-order partial differential equations with time fractional derivative proposed by Caputo and Fabrizio in a one-dimensional space. Two finite difference schemes are established via Grünwald formula.

The Kernel of the Distributed Order Fractional Derivatives with an Application to Complex Materials

open access: yesFractal and Fractional, 2017
The extension of the fractional order derivative to the distributed order fractional derivative (DOFD) is somewhat simple from a formal point of view, but it does not yet have a simple, obvious analytic form that allows its fast numerical calculation ...

Quasi-Projective Synchronization of Distributed-Order Recurrent Neural Networks

open access: yesFractal and Fractional, 2021
In this paper, the quasi-projective synchronization of distributed-order recurrent neural networks is investigated. Firstly, based on the definition of the distributed-order derivative and metric space theory, two distributed-order differential ...

On a System of Equations with General Fractional Derivatives Arising in Diffusion Theory

open access: yesFractal and Fractional, 2023
A novel two-compartment model for drug release was formulated. The general fractional derivatives of a specific type and distributed order were used in the formulation. Earlier used models in pharmacokinetics with fractional derivatives follow as special

Chelyshkov polynomials method for distributed-order time fractional nonlinear diffusion-wave equations

open access: yesResults in Physics, 2023
This work deals with the distributed-order time fractional nonlinear diffusion-wave equations. These equations are generated by replacing the first- and second-order time derivative terms with the distributed-order fractional derivative terms.
