Impact of periodic vaccination in SEIRS seasonal model
Enrique C. Gabrick, Eduardo L. Brugnago, Silvio L. T. de Souza +6
We study three different strategies of vaccination in a SEIRS (Susceptible--Exposed--Infected--Recovered--Susceptible) seasonal forced model, which are: () continuous vaccinatio…
Unpredictability in seasonal infectious diseases spread
Enrique C. Gabrick, Elaheh Sayari, Paulo R. Protachevicz +7
In this work, we study the unpredictability of seasonal infectious diseases considering a SEIRS model with seasonal forcing. To investigate the dynamical behaviour, we compute bifu…
Effect of two vaccine doses in the SEIR epidemic model using a stochastic cellular automaton
Enrique C. Gabrick, Paulo R. Protachevicz, Antonio M. Batista +6
In this work, to support decision making of immunisation strategies, we propose the inclusion of two vaccination doses in the SEIR model considering a stochastic cellular automaton…
Characterization in bi-parameter space of a non-ideal oscillator
S. L. T. de Souza, A. M. Batista, M. S. Baptista +2
We investigate the dynamical behavior of a non-ideal Duffing oscillator, a system composed of a mass-spring-pendulum driven by a DC motor with limited power supply. To identify new…
Super persistent transient in a master-slave configuration with Colpitts oscillators
R. C. Bonetti, S. L. T. de Souza, A. M. Batista +5
Master-slave systems have been intensively investigated to model the application of chaos to communications. We considered Colpitts oscillators coupled according to a master-slave…
Torsion-Adding and Asymptotic Winding Number for Periodic Window Sequences
E. S. Medeiros, R. O. Medrano-T, I. L. Caldas +1
In parameter space of nonlinear dynamical systems, windows of periodic states are aligned following routes of period-adding configuring periodic window sequences. In state space of…
Replicate Periodic Windows in the Parameter Space of Driven Oscillators
E. S. Medeiros, S. L. T. de Souza, R. O. Medrano-T. +1
In the bi-dimensional parameter space of driven oscillators, shrimp-shaped periodic windows are immersed in chaotic regions. For two of these oscillators, namely, Duffing and Josep…
