In this work, we replaced the integer derivative with Caputo derivative to model the
transmission dynamics of measles in an epidemic situation. We began by recalling some …

Chlamydiosis remains a major public health concern in both developed and develo**
countries due to its effects on the human reproductive system. While limited modeling …

The objective of this article is to present a novel algorithm that can efficiently address
fractional quadratic optimal control problems (FQOCPs) through the application of the …

In this paper, our aim is to solve an optimal control problem by using an operator theoretic
approach in the sense of Caputo fractional derivative. We first reduce the fractional …

To explore the impact of the COVID-19 vaccination rate and immune loss rate on the
pandemic, this paper proposes a fractional-order SIV 1 V 2 S epidemic model with …

The goal of this work is the formulation and analysis of a Covid-19 transmission dynamics
model which takes into account two doses of the vaccination process, confinement, and …

This study presents a mathematical model to investigate the patterns of transmission in
lymphatic filariasis. The model considers chronic, acute, and asymptomatic individuals and …

The main aim of this study was to apply an analytical method to solve a nonlinear system of
fractional differential equations (FDEs). This method is the Adomian decomposition method …

A fractional-order coronavirus disease of 2019 (COVID-19) model is constructed of five
compartments in the Caputo-Fabrizio sense. The main aim of the paper is to study the effects …

In December 2019, the novel Coronavirus, also known as 2019-nCoV or SARS-CoV-2 or
COVID-19, was first recognized as a deadly disease in Wuhan, China. In this paper, we …
