Brownian motion

The COVID-19 is a major danger that threatens the whole world.  In this context, mathematical modeling is a very powerful tool for knowing more about how such a disease is transmitted within a host population of humans.  In this regard, we propose in the current study a stochastic epidemic model that describes the COVID-19 dynamics under the application of quarantine and coverage media strategies, and we give a rigorous mathematical analysis of this model to obtain an overview of COVID-19 dissemination behavior.

The objective of this research is to examine the steady incompressible two-dimensional hydromagnetic boundary layer flow of nanofluid passing through a stretched sheet in the influence of viscous and ohmic dissipations.  The present problem is obtained with the help of an analytical technique called DTM-Pade Approximation.  The mathematical modeling of the flow is considered in the form of the partial differential equation and is transformed into a differential equation through suitable similarity transformation.  The force of fixed parameters like thermophoresis number
