A Compartmental Model for Assessing Effects of COVID-19 Vaccination in Thailand

چکیده
A dynamical model for COVID-19 spread relating to non-pharmaceutical interventions and vaccination is mathematically generated by adding a gradual compartment the susceptible population considering only symptomatic infectious stage. In our model, there are seven compartments dividing given into , vaccinated src=image/17628733_02.gif>, exposed src=image/17628733_03.gif>, infected src=image/17628733_04.gif>, quarantined src=image/17628733_05.gif>, recovered src=image/17628733_06.gif> death src=image/17628733_07.gif> groups, respectively. Then, theoretically analysis investigating free endemic equilibrium points, computing reproduction number of this denoted as src=image/17628733_08.gif> using next generation matrix. If src=image/17628733_09.gif>, then transmission increases exponentially depends on vaccine efficacy. On other hand, if src=image/17628733_10.gif>, occurs disease eradication. The risk from infection can be importantly reduced whenever intake vaccines exceeds one dose. numerical results reveal that nonpharmaceutical ways administered effective against current variants COVID-19, additional efforts such third booster shot should considered implemented greatly mitigate risks emerging virus. Moreover, combining different types appeared possible way give better protection well.

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...

In this paper, a model is proposed based on the different levels of social restrictions for the COVID-19 spread restraint in Iran. Also, a Genetic Algorithm (GA) identifies parameters of model using reported main data from the Iranian Ministry of Health and simulated data based on proposed model. Whereas Model Predictive Control (MPC) is a popular method which has been widely used in process ...
