A fractional B-spline collocation method for the numerical solution of fractional predator-prey models [PDF]
, 2018 We present a collocation method based on fractional B-splines for the solution of fractional differential problems. The key-idea is to use the space generated by the fractional B-splines, i.e., piecewise polynomials of noninteger degree, as approximating

Exoskeleton Hand Control by Fractional Order Models [PDF]
Sensors, 2019 This paper deals with the fractional order control for the complex systems, hand exoskeleton and sensors, that monitor and control the human behavior. The control laws based on physical significance variables, for fractional order models, with delays or without delays, are proposed and discussed.

A Total Fractional-Order Variation Model for Image Restoration with Non-homogeneous Boundary Conditions and its Numerical Solution [PDF]
, 2015 To overcome the weakness of a total variation based model for image restoration, various high order (typically second order) regularization models have been proposed and studied recently.

A new fractional-order compartmental disease model
Alexandria Engineering Journal, 2020 In this paper, we propose a new SEIRS model and are concerned with stability and numerical solutions of the model. The model is generated under certain assumptions such as individuals are vaccinated or have a special treatment but do not carry lifelong ...

First order plus frequency dependent delay modeling : new perspective or mathematical curiosity? [PDF]
, 2019 The first-order-plus-dead-time model (FOPDT) is a popular simplified representation of higher order dynamics. However, a well known drawback is the rapid decrease of the frequency response accuracy with increasing process order.

Fractional-Order Modelling in Modelica [PDF]
Linköping Electronic Conference Proceedings, 2015 Most dynamic systems with a basis in nature can be described using Differential-Algebraic Equations (DAE), and hence be modelled using the modelling language Modelica. However, the concept of DAEs can still be generalised, when differential operators of non-integer order are considered.

Discrete maximal regularity of time-stepping schemes for fractional evolution equations [PDF]
, 2017 In this work, we establish the maximal $\ell^p$-regularity for several time stepping schemes for a fractional evolution model, which involves a fractional derivative of order $\alpha\in(0,2)$, $\alpha\neq 1$, in time.

Dynamics of a Fractional Order Eco-Epidemiological Model
Journal of Tropical Life Science, 2017 In this paper, we propose a fractional order eco-epidemiological model. We considere the existence of time memory in the growth rate of the three populations.

A Caputo Fabrizio fractional order model for control of glucose in insulin therapies for diabetes
Ain Shams Engineering Journal, 2020 Many fresh definitions of fractional derivatives have been suggested and used in recent years to produce mathematical models with memory, background, or non-local effects for a broad range of real-world structures.
