26 p, 3.6 MB On a Discrete SEIR Epidemic Model with Two-Doses Delayed Feedback Vaccination Control on the Susceptible / De la Sen, Manuel (University of the Basque Country) ; Alonso-Quesada, Santiago (University of the Basque Country) ; Ibeas, Asier (Universitat Autònoma de Barcelona. Departament de Telecomunicació i Enginyeria de Sistemes) ; Nistal, Raul (University of the Basque Country)
A new discrete susceptible-exposed-infectious-recovered (SEIR) epidemic model is presented subject to a feedback vaccination effort involving two doses. Both vaccination doses, which are subject to a non-necessarily identical effectiveness, are administrated by respecting a certain mutual delay interval, and their immunity effect is registered after a certain delay since the second dose. [...]

31 p, 5.0 MB On the use of entropy issues to evaluate and control the transients in some epidemic models / De la Sen, Manuel (Universidad del País Vasco. Instituto de Investigación y Desarrollo de Procesos) ; Nistal, Raul (Universidad del País Vasco. Instituto de Investigación y Desarrollo de Procesos) ; Ibeas, Asier (Universitat Autònoma de Barcelona. Departament de Telecomunicació i Enginyeria de Sistemes) ; Garrido, Aitor J. (Universidad del País Vasco. Instituto de Investigación y Desarrollo de Procesos)
This paper studies the representation of a general epidemic model by means of a first-order differential equation with a time-varying log-normal type coefficient. Then the generalization of the first-order differential system to epidemic models with more subpopulations is focused on by introducing the inter-subpopulations dynamics couplings and the control interventions information through the mentioned time-varying coefficient which drives the basic differential equation model. [...]
