Analysis of fractional model of guava for biological pest control with memory effect [PDF]

open access: yesJournal of Advanced Research, 2021
Introduction: Fractional operators find their applications in several scientific and engineering processes. We consider a fractional guava fruit model involving a non-local additionally non-singular fractional derivative for the interaction into guava ...

Model Fractional Chern Insulators [PDF]

open access: yesPhysical Review Letters, 2016
We devise local lattice models whose ground states are model fractional Chern insulators---Abelian and non-Abelian topologically ordered states characterized by exact ground state degeneracies at any finite size and infinite entanglement gaps.

Tempered fractional LES modeling [PDF]

open access: yesJournal of Fluid Mechanics, 2021
The presence of non-local interactions and intermittent signals in the homogeneous isotropic turbulence grant multi-point statistical functions a key role in formulating a new generation of large-eddy simulation (LES) models of higher fidelity. We establish a tempered fractional-order modelling framework for developing non-local LES subgrid-scale ...

Fractional SIR epidemiological models [PDF]

open access: yesScientific Reports, 2020
Abstract The purpose of this work is to make a case for epidemiological models with fractional exponent in the contribution of sub-populations to the incidence rate. More specifically, we question the standard assumption in the literature on epidemiological models, where the incidence rate dictating propagation of infections is taken ...

Modelling Fractional Behaviours Without Fractional Models [PDF]

open access: yesFrontiers in Control Engineering, 2021
This paper first warns about the confusion or rather the implicit link that exists in the literature between fractional behaviours (of physical, biological, thermal, etc. origin) and fractional models. The need in the field of dynamic systems modelling is for tools that can capture fractional behaviours that are ubiquitous.

Fractional Model of the Deformation Process

open access: yesFractal and Fractional, 2022
The article considers the fractional Poisson process as a mathematical model of deformation activity in a seismically active region. The dislocation approach is used to describe five modes of the deformation process.

Fractional SIS Epidemic Models [PDF]

open access: yesFractal and Fractional, 2020
In this paper, we consider the fractional SIS (susceptible-infectious-susceptible) epidemic model (α-SIS model) in the case of constant population size. We provide a representation of the explicit solution to the fractional model and we illustrate the results by numerical schemes.

Stability and Optimal Control of a Fractional SEQIR Epidemic Model with Saturated Incidence Rate

open access: yesFractal and Fractional, 2023
The fractional differential equation has a memory property and is suitable for biomathematical modeling. In this paper, a fractional SEQIR epidemic model with saturated incidence and vaccination is constructed.

Fractional Mathematical Model McSherry

open access: yesВестник КРАУНЦ. Физико-математические науки, 2023
В статье предложено обобщение математической модели Макшерри для моделирования искусственной электрокардиограммы — изменяющегося во времени сигнала, отражающий ионный ток, который заставляет сердечные волокна сокращаться, а затем расслабляться. Обобщение математической модели Макшерри заключается в учете свойства наследственности (памяти) динамического

Cardiovascular Circulatory System and Left Carotid Model: A Fractional Approach to Disease Modeling

open access: yesFractal and Fractional, 2022
Cardiovascular diseases (CVDs) remain the leading cause of death worldwide, according to recent reports from the World Health Organization (WHO). This fact encourages research into the cardiovascular system (CVS) from multiple and different points of ...
