Fractional Integration and Differentiation by new Transformation

open access: yesWasit Journal for Pure Sciences, 2023
In opposite to differentiation and integration of integer order, an important type of differentiation and integration is the so - called “ Fractional Calculus (FC) ” in which the differentiation and integration is of non-integer order.

Multivariable Fractional-Order Controller Design for a Nonlinear Dual-Tank Device

open access: yesFractal and Fractional, 2023
Fractional calculus is defined by expanded integer order integration and differentiation. In this paper, multiple mathematical models of a nonlinear dual-tank device are precisely formulated by fractional calculus.

Spectral analysis of variable-order multi-terms fractional differential equations

open access: yesOpen Physics, 2023
In this work, a numerical scheme based on shifted Jacobi polynomials (SJPs) is deduced for variable-order fractional differential equations (FDEs). We find numerical solution of consider problem of fractional order. The proposed numerical scheme is based

Numerical simulation of Covid-19 model with integer and non-integer order: The effect of environment and social distancing

open access: yesResults in Physics, 2023
We consider an epidemiological model that takes into account pathogens in the environment and social distancing. Such model with six classes has been updated with fractional differential operators and piecewise differential operators.

The Kuznets Environmental Curve Using Fractional Integration and Long Range Dependence Techniques [PDF]

open access: yesInternational Journal of New Political Economy, 2020
This paper investigates empirically the Kuznets environmental curve in nineteen industrialized countries by using updated techniques in time series analysis and based on the concepts of long range dependence and fractional integration. Unlike most of the

On the stability of some fractional-order non-autonomous systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2007
The fractional calculus (integration and differentiation of fractional-order) is a one of the singular integral and integro-differential operators. In this work a class of fractional-order non-autonomous systems will be considered.

Fractional Integration and Differentiation of the Generalized Mathieu Series

open access: yesAxioms, 2017
We aim to present some formulas for the Saigo hypergeometric fractional integral and differential operators involving the generalized Mathieu series S μ ( r ) , which are expressed in terms of the Hadamard product of the generalized Mathieu ...

Why Do Big Data and Machine Learning Entail the Fractional Dynamics?

open access: yesEntropy, 2021
Fractional-order calculus is about the differentiation and integration of non-integer orders. Fractional calculus (FC) is based on fractional-order thinking (FOT) and has been shown to help us to understand complex systems better, improve the processing ...
