Estimation of COVID-19 dynamics “on a back-of-envelope”: Does the simplest SIR model provide quantitative parameters and predictions?
Basing on existence of the mathematically sequential reduction of the three-compartmental (SusceptibleInfected-Recovered/Removed) model to the Verhulst (logistic) equation with the parameters determined
by the basic ...
Modelos SIR e SIRS aplicados à dinâmica da Covid-19 no estado do Amapá e região metropolitana
(Universidade Estadual Paulista (Unesp), 2022-06-03)
O benefício em estudar os modelos epidemiológicos e sua importância em analisar a maneira que uma doença pode se comportar em um meio, tais como a quantidade de pessoas suscetíveis de uma população a se infectarem com o ...
A fuzzy cellular automata for SIR compartmental models
(2013-12-01)
We propose a representation of the dynamics of epidemics through a compartmental SIR (Susceptible - Infected - Recovered) model, with the combined use of geo-referenced cellular automata and fuzzy systems. In this model, ...
Stochastic lattice gas model describing the dynamics of the SIRS epidemic process
(ELSEVIER SCIENCE BV, 2010)
We study a stochastic process describing the onset of spreading dynamics of an epidemic in a population composed of individuals of three classes: susceptible (S), infected (I), and recovered (R). The stochastic process is ...
Interval observer for SIR epidemic model subject to uncertain seasonality
(EMAp - Escola de Matemática Aplicada, 2016)
The issue of state estimation is considered for a SIR model with seasonal variations and uncertainties in the transmission rate. Assuming continuous measurement of the number of new infectives per unit time, a class of ...
Spreading of infections on random graphs: A percolation-type model for COVID-19
We introduce an epidemic spreading model on a network using concepts from percolation theory. The
model is motivated by discussing the standard SIR model, with extensions to describe effects of lockdowns within a population. ...
