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

Developing a Method for Assessing and Managing the Risk of Covid-19; Rapid Covid-19 Hazard analysis

Background and aims: Work environments are constantly changing under the influence of various factors and newer risks are introduced. Rapid changes in science and technology, increasing the complexity of the industry, increased system integration and other factors have been shown to increase total risk in the past few decades. As well, risk management becomes increasingly critical in decreasing...

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...

Promote COVID-19 vaccination uptake: a letter to editor

Covid-19 Vaccination and Reactivation of Varicella Zoster Virus

Introduction: After COVID-19 pandemic in 2020 that mostly affects upper respiratory tract, the scientists investigated an effective vaccine against the virus. As the vaccination of general population started some patients were visited with varicella zoster virus activation following the COVID vaccine.

Design and implementation of a model predictive controller for the COVID-19 spread restraint in Iran

 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 ...
