Ma’mon Abu Hammad, Iqbal H. Jebril, Iqbal M. Batiha, Amer Mansour Dababneh,
Abstract :
In this work, the so-called conformable fractional derivative definition is employed to obtain the fractional Frobenius series solutions around the regular α-singular point x = 0 for the confluent α-hypergeometric differential equation. Of course, such solutions for this equation in its classical case are just confluent hypergeometric functions. The proposed method is straightforward to be applied as an algorithm.



CESAR Torres Ledesma,
Abstract :
Using minimax techniques involving Cerami sequences, we prove the existence of at least one pair of positive solutions for an fractional Hamiltonian system in R with potentials vanishing at infinity and subcritical nonlinearities which are super-linear at the origin and at infinity. We establish new estimates in order to prove the boundedness of a Cerami sequence. Our result is new even in the integer case.


Numerical investigation on the solution of a space-fractional via preconditioned SOR iterative method

Praveen Agarwal,
Abstract :
This paper considers a numerical investigation on the solution of a one-dimensional linear space-fractional partial differential equation with the application of an unconditionally implicit finite difference method and the Caputos space-fractional derivative. We formulate the Caputosimplicit finite difference approximation equation to form a corresponding linear system in which its coefficient matrix is large-sized and has a great sparsity. We construct a preconditioned linear system intending to speed up the convergence rate in computing the solutions of the linear system using the SOR iterative method. We present two examples of the one-dimensional linear space-fractional partial differential equation problem to illustrate the effectiveness and efficiency of our proposed PSOR iterative method. Through the investigation, the numerical results show that the proposed PSOR iterative method is superior to the Preconditioned Gauss-Seidel and Gauss-Seidel iterative methods in terms of efficiency.

Numerical simulations are presented to figure out the features of using the non-integer order (fractional order) models in epidemiology.


Fractional-Order Delayed Salmonella Transmission Model: A Numerical Simulation

N. H. Sweilam,
Abstract :
In this paper, a fractional dynamical model of Salmonella with time delay is studied numerically. The proposed model is administered by a system of fractional delay differential equations, where the fractional derivative is defined in the sense of the Caputo definition. The parameters are modified regarding to the order of the fractional derivative. The stability of the disease free equilibrium point and endemic equilibrium point is investigated for any time delay. Weighted difference numerical technique is introduced to simulate the proposed model. This scheme was unconditionally stable when the weight factor is less than 1. Numerical simulations with some comparison are introduced to show the applicability and effectivity of the proposed method to solve such stiff systems of fractional delay differential equations and to confirm the theoretical studies.

Ravi P. Agarwal,
Abstract :
Recently,manyresearchershavepublishedworkontheHermite-Hadamardinequalities,duetotheirimmenseimportancein the fields of numerical analysis, statistics, optimization and convexity theory. In this paper, certain new Hermite-Hadamard type integral inequalities have been established using the (k − r) Riemann-Liouville fractional integral operator. We present various inequalities based on different types of the convex functions such as quasi-convex, l-convex, η-convex in the second sense and (β,l)-convex functions. Also, we derive Hermite-Hadamard type inequalities for the product of two l-convex functions and two (β,l)-convex functions using (k − r) Riemann-Liouville fractional integral operator. The results obtained in our work will be helpful in the further study of the convex functions and in the evaluation of the certain mathematical problems.


Iterative Methods for Solving Seventh-Order Nonlinear Time Fractional Equations

Lanre Akinyemi, Olaniyi S. Iyiola, Isaac Owusu-Mensah,
Abstract :
The fundamental aim of the present work is to investigate the numerical solutions of the seventh order Caputo fractional time Kaup-Kupershmidt, Sawada-Kotera and Lax’s Korteweg-de Vries equations using two reliable techniques, namely, the fractional reduced differential transform method and q-homotopy analysis transform method. These equations are the mathematical formulation of physical phenomena that arise in chemistry, engineering and physics. For instance, in the motions of long waves in shallow water under gravity, nonlinear optics, quantum mechanics, plasma physics, fluid mechanics and so on. With these two methods, we construct series solution to these problems in the recurrence relation form. We present error estimates to further investigate the accuracy and reliability of the proposed techniques. The outcome of the study reveals that the two techniques used are computationally accurate, reliable and easy to implement when solving fractional nonlinear complex phenomena that arise in physics, biology, chemistry and mathematics.

Muhammad Farman, Ali Raza, Ali Akgu ̈l, Muhammad Umer Saleem, Aqeel Ahmad, Muhammad Sajid Iqbal,
Abstract :
In this paper, nonlinear fractional order HIV/AIDS mathematical model is discussed for the complex transmission of the disease epidemic problems. It is accepted that susceptible wind up contaminated by means of sexual contacts with infective and all infective eventually create AIDS. The point of this task was to amend transmission models recently created to represent HIV transmission and AIDS related mortality. The Caputo-Fabrizio fractional derivative operator of order $\beta \in (0, 1]$ is used to obtain fractional differential equations structure. The stability fractional order model was developed and the unique non-negative solution was tested. The numerical simulations are performed using an iterative technique. Some new results are being viewed with the help of Sumudo transform. Nonetheless, according to Banach, the related findings are given nonlinear functional analysis and fixed point theory. However, mathematical simulations are also acknowledged to evaluate the impact of the models parameter by decreasing the fractional values and showing the effect of the $\beta$ fractional parameter on our solutions obtained. The impact of various parameters is represented graphically.

Laplace with Adomian Decomposition Method successfully solved the fractional differential equations. Ultimately, numerical simulations are also developed to evaluate the effects of the device parameter on spread of disease and effect of fractional parameter $\beta$ on obtained solution which are also assessed by tabulated results.


The Drug Administration via Fractional-order PI^\lambda D^\delta -Controller

Igbal Batiha,
Abstract :
Amiodarone is one of the most commonly used antiarrhythmic drugs. Some of its features, like its anomalous and its non-exponential pharmacokinetics make it so important in clinical implications. Recently, more accurate fractional-order models were proposed to describe its pharmacokinetics in a consistent manner. Hence, fractional-order PID controllers will be used and tuned to regulate the dynamic behavior of the drug administration and to provide good closed-loop response. This controller is designed based on the Particle Swarm Optimization (PSO) algorithm by approximating s^alpha; 0 < alpha <= 1. The PSO algorithm is used to minimize the ITAE, IAE, ISE and ITSE error functions. A comparison between Oustaloup’s and El-Khazali’s approximations are presented to show the effectiveness and the cost of the controller design. All results are verified via numerical simulations.

Trigonometric Commutative Caputo fractional Korovkin theory for Stochastic processes

George A. Anastassiou,
Abstract :
Here we consider and study from the trigonometric point of view ex- pectation commutative stochastic positive linear operators acting on L1- continuous stochastic processes which are Caputo fractional differentiable. Under some mild, general and natural assumptions on the stochastic processes we produce related trigonometric Caputo fractional stochastic Shisha-Mond type inequalities pointwise and uniform. All convergences are produced with rates and are given by the trigonometric fractional stochastic inequalities involving the first modulus of continuity of the ex- pectation of the α-th right and left fractional derivatives of the engaged stochastic process, α > 0, α ∈/ N. The amazing fact here is that the basic non-stochastic real Korovkin test functions assumptions impose the conclusions of our trigonometric Caputo fractional stochastic Korovkin theory. We include also a detailed trigonometric application to stochastic Bernstein operators.

Dynamics and Sensitivity Analysis of Fractional-Order Delay Differential Model For Coronavirus Infection

Fathalla A. Rihan, Velmurugan Gandhi,
Abstract :
Recently, an outbreak of a new coronavirus (CoV) that began in the Chinese city of Wuhan has already killed at least 106 people in China, according to data released early Tuesday 21 January 2020. In this article, we provide a mathematical model to give us a better understanding of what drives the intensity of symptoms, infectivity of the virus and the host, and duration of the disease. The model is governed by a system fractional-order differential equations with time-delay. We incorporate a fractional-order and time-delay in the model to naturally represent both long-run memory and non-locality effects in the dynamics of the model. We investigate the qualitative behaviour of the model and deduce some interesting sufficient conditions which ensure the asymptotic stability of the steady states. Sensitivity analyses are conducted to provide insight into how uncertainty in the parameters affects the model outputs and which parameters tend to drive these variations. We investigate the sensitivity to variations in the rate of interferon, in the rate of innate immunity cells, rate of adaptive immunity cells, and in pathogen virulence. Some numerical simulations are provided to show the effectiveness of the derived theoretical results. This study may help in delineate the interaction between respiratory viruses and the host immune system, and determine the most effective parameters for treatment.

Samir Hadid,
Abstract :
The economic order quantity (EOQ) pattern resolves the value that minimizes the collection aggregate of cost expense functions. One of the resent active models is that based on entropy, which is called entropy order quantity (EnOQ). It’s recommended that it might be potential to develop production systems presentation by employing the theory of information (Entropy). In this effort, we suggest a model for EOQ, by using the conformable calculus calling conformable entropy order quantity (C-EnOQ). In this case, we deliver the cost functions with respect to time in a returning period. In this model, we investigate the connected optimization problem and develop an undisturbed technique for computing a bounded interval covering the optimal sequence distance, utilizing the Tsallis fractional entropy. In addition, for an extraordinary class of transport functions, we investigate these cost functions to calculate the optimal size.

The most commonly developed inventory models are the classical economic order quantity model, is governed by the integer order differential equations. We want to come out from the traditional thought i.e. classical order inventory model where the memory phenomena are absent. Here, we want to incorporate the memory effect that is based on the fact economic agents remember the history of changes of exogenous and endogenous variables. In this paper, we have proposed and solved a fractional order economic order quantity model with constant demand rate where the demand is fully backlogged during shortage time. Finally, a numerical example has been illustrated for this model to show the memory dependency of the system. The numerical example clears that for the considered system the profit is maximum in long memory affected system compared to the low memory affected or memory less system.
