Fractional order model of a greenhouse

IREC2015 The Sixth International Renewable Energy Congress, 2015
A fractional order model that describes thermal and moisture behaviors in the greenhouse was done. In modeling the greenhouse many authors use a simple model of soil that neglect the heat / mass coupling, furthermore they use the discretization techniques for solving the heat conduction equation leading to a very high order model, this causes problems ...

Fractional Order Models

2015
In a letter to L’Hospital in 1695, Leibniz raised the possibility of generalizing the operation of differentiation to non-integer orders and L’Hospital asked what would be the result of half-differentiating a variable. Leibniz in an open letter dated September 30, 1695 replied “It leads to a paradox, from which 1 day useful consequences will be drawn”.

Identification of fractional order model for a voltammetric E-tongue system

, 2020
A method to estimate the fractional order model of a voltammetric electronic tongue (E-tongue) system with five working electrodes has been presented in this paper. The method uses fractional order system (FOS) identification to obtain a fractional order

CHAOS IN FRACTIONAL-ORDER POPULATION MODEL

International Journal of Bifurcation and Chaos, 2012
This paper presents a fractional-order population model which consists of the two-predators and one-prey scheme. For this new model, the numerical solution is derived and the simulations are performed for various sets of model parameters together with stability analysis for commensurate and incomensurate orders of the fractional-order population model.

On the fractional-order modeling of wine

European Food Research and Technology, 2016
This paper uses electrical impedance spectroscopy for characterizing different varieties of wine and compares the results with standard chemical analysis. In a first phase, the electrical impedance of wine samples is measured and modeled by means of fractional-order transfer functions.

On the Fractional Order Model of Viscoelasticity

Mechanics of Time-Dependent Materials, 2005
Fractional order models of viscoelasticity have proven to be very useful for modeling of polymers. Time domain responses as stress relaxation and creep as well as frequency domain responses are well represented. The drawback of fractional order models is that the fractional order operators are difficult to handle numerically. This is in particular true

Fractional order model of immune cells influenced by cancer cells

Mathematical Modelling of Natural Phenomena, 2019
In this paper, we study the mathematical model of interaction cancer cells and immune system cells presented Castiglione and Piccoli. As the interaction between cancer cells and the immune system is weak, when the immune system of the body begins to ...

Fractional-Order Models of Vegetable Tissues

2017
In this chapter, we probe a bit further into the study of electrical impedance spectroscopy and what it can tell us about how nature does things. Vegetable matter can be thought of as nature’s fractional-order (FO) devices. They exhibit FO dynamics over a very wide frequency range. We investigate living tissue from the perspective of the electrochemist

A fractional‐order model with time delay for tuberculosis with endogenous reactivation and exogenous reinfections

Mathematical methods in the applied sciences, 2019
In this paper, we propose a fractional‐order delay differential model for tuberculosis (TB) transmission with the effects of endogenous reactivation and exogenous reinfections.
