چکیده

‎ Since the first outbreak in Wuhan, China, December 31, 2019, COVID-19 pandemic ‎has been spreading to many countries world. The ongoing has caused a ‎major global crisis, with 554,767 total confirmed cases, 484,570 recovered and ‎‎12,306 deaths Iraq as of February 2, 2020. In absence any effective therapeutics or drugs ‎and an unknown epidemiological life cycle, predictive mathematical models can aid ‎the understanding both control management coronavirus disease. Among important ‎factors that helped rapid spread epidemic are immigration, travelers, foreign workers, students. this work, we develop model study dynamical ‎behavior pandemic, involving immigrants' effects possibility re-infection. ‎Firstly, studied positivity roundedness solution proposed model. stability ‎results at disease-free equilibrium point were presented when . Further, it was proven will persist uniformly Moreover, ‎confirmed occurrence local bifurcation (saddle-node, pitchfork, transcritical). Finally, ‎theoretical analysis numerical results shown be consistent.

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Mathematical Model of Novel COVID-19 and Its Transmission Dynamics

In this paper, we formulated a dynamical model of COVID-19 to describe the transmission dynamics of the disease. The well possedness of the formulated model equations was proved. Both local and global stability of the disease free equilibrium and endemic equilibrium point of the model equation was established using basic reproduction number. The results show that, if the basic reproduction numb...

Modeling and analysis of the spread of the COVID-19 pandemic using the classical SIR model

In this paper modeling, analysis and prediction of novel epidemic of COVID-19 are concerned to identify effective spread parameters of it in Iran. For this purpose, the basic susceptible-infected-removed (SIR) model is used which has two parameters: the infection rate and remove rate. The occurrence of several maximum points in the Iranian data and the single peak of the SIR model makes it impo...
