Epidemic Model of Leptospirosis Containing Fractional Order

open access: yesAbstract and Applied Analysis, 2014
We study an epidemic model of leptospirosis in fractional order numerically. The multistep generalized differential transform method is applied to find the accurate approximate solution of the epidemic model of leptospirosis disease in fractional order ...

Development of Fractional Order Modeling of Voltage Source Converters

open access: yesIEEE Access, 2020
This paper proposes a mathematical fractional order modelling of Voltage Source Converters (VSC). Fractional behaviour helps to model and describe a real object more accurately than the integer order model.

Review of Some Promising Fractional Physical Models [PDF]

open access: yes, 2015
Fractional dynamics is a field of study in physics and mechanics investigating the behavior of objects and systems that are characterized by power-law non-locality, power-law long-term memory or fractal properties by using integrations and ...

MOND-like Fractional Laplacian Theory

open access: yes, 2020
I provide a derivation of some characteristic effects of Milgrom's modified Newtonian dynamics (MOND) from a fractional version of Newton's theory based on the fractional Poisson equation.

Fractional-Order Zener Model with Temperature-Order Equivalence for Viscoelastic Dampers

open access: yesFractal and Fractional, 2023
Viscoelastic (VE) dampers show good performance in dissipating energy, being widely used for reducing vibration in engineering structures caused by earthquakes and winds. Experimental studies have shown that ambient temperature has great influence on the

A comparative study of fractional order PIλ /PIλ Dμ tuning rules for stable first order plus time delay processes [PDF]

open access: yes, 2016
Conventional PID tuning methods may not be sufficient to deal with complex processes of modern industry. For better control, fractional order PIλDµ controller was introduced as the generalization of classical PID controller with the help of non-integer ...
