Advanced materials modelling via fractional calculus: challenges and perspectives

open access: yesPhilosophical Transactions of the Royal Society A, 2020
Fractional calculus is now a well-established tool in engineering science, with very promising applications in materials modelling. Indeed, several studies have shown that fractional operators can successfully describe complex long-memory and multiscale ...

Fuzzy clustering to classify several regression models with fractional Brownian motion errors

open access: yesAlexandria Engineering Journal, 2020
Clustering regression models fitted on the dataset is one of the most ubiquitous issues in different fields of sciences. In this research, fuzzy clustering method is used to cluster regression models with fractional Brownian motion errors that can be ...

Non-local fractional model of rate independent plasticity [PDF]

open access: yes, 2013
In the paper the generalisation of classical rate independent plasticity using fractional calculus is presented. This new formulation is non-local due to properties of applied fractional differential operator during definition of kinematics.

A fractional power approach to fractional calculus

open access: yesJournal of Mathematical Analysis and Applications, 1990
AbstractA theory of fractional powers of operators on an arbitrary Fréchet space is discussed. As special cases, multivariable fractional integrals and derivatives defined on certain spaces of test functions and generalised functions are obtained. In particular, properties of the two-dimensional Riesz fractional integral are determined and used to ...

On New Unified Bounds for a Family of Functions via Fractional q-Calculus Theory

open access: yesJournal of Function Spaces, 2020
The present article deals with the new estimates in q-calculus and fractional q-calculus on a time scale Tt0=0∪t:t=t0qn,n is a nonnegative integer, where t0∈ℝ and ...

A naturally emerging bivariate Mittag-Leffler function and associated fractional-calculus operators [PDF]

open access: yesComputational and Applied Mathematics, 2020
We define an analogue of the classical Mittag-Leffler function which is applied to two variables, and establish its basic properties. Using a corresponding single-variable function with fractional powers, we define an associated fractional integral ...

Joining Spacetimes on Fractal Hypersurfaces

open access: yes, 2018
The theory of fractional calculus is attracting a lot of attention from mathematicians as well as physicists. The fractional generalisation of the well-known ordinary calculus is being used extensively in many fields, particularly in understanding ...
