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 superlinear at the origin and at infinity.

Numerical investigation on the solution of a spacefractional via preconditioned SOR iterative method


Praveen Agarwal,


Abstract
: 

This paper considers a numerical investigation on the solution of a onedimensional linear spacefractional partial differential equation with the application of an unconditionally implicit finite difference method and the Caputos spacefractional derivative. We formulate the Caputosimplicit finite difference approximation equation to form a corresponding linear system in which its coefficient matrix is largesized 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 onedimensional linear spacefractional 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 GaussSeidel and GaussSeidel iterative methods in terms of efficiency.

FractionalOrder 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.

Lanre Akinyemi,
Olaniyi S. Iyiola,
Isaac OwusuMensah,


Abstract
: 

The fundamental aim of the present work is to investigate the numerical solutions of the seventh order Caputo fractional time KaupKupershmidt, SawadaKotera and Lax’s Kortewegde Vries equations using two reliable techniques, namely, the fractional reduced differential transform method and qhomotopy 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.

Our main tool here is using fundamental tools, namely Banach fixed point theorem and Sobolev embeddings.

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 CaputoFabrizio 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 nonnegative 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.

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 Fractionalorder 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
nonexponential pharmacokinetics make it so important in clinical implications. Recently, more accurate fractionalorder models were
proposed to describe its pharmacokinetics in a consistent manner. Hence, fractionalorder PID controllers will be used and tuned to
regulate the dynamic behavior of the drug administration and to provide good closedloop 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 ElKhazali’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 ShishaMond 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 αth right and left fractional derivatives of the engaged stochastic process, α > 0, α ∈/ N. The amazing fact here is that the basic nonstochastic 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.

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 fractionalorder differential equations with timedelay. We incorporate a fractionalorder and timedelay in the model to naturally represent both longrun memory and nonlocality 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.

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.

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.
