(2012)In this paper, a new type of mathematical model to represent certain processes with impulsive dynamic behavior is introduced. The main assumption is that the next impulse time is determined by three fundamental elements: ...
-
(2012)We present a model of single species fishery which alternates closed seasons with pulse captures. The novelty is that the length of a closed season is determined by the remaining stock size after the last capture. The ...

(2011)This work presents a new pulse vaccination strategy for a SIS (susceptibleinfectivesusceptible) disease in an endemic context. Here, given a time of vaccination, the instant of the next one is not predetermined, but it is ...
-
(Universidad de Chile, 2003)Este trabajo es un estudio de las ecuaciones diferenciales con efecto impulsivo en tiempos variables. Algunos de los comportamientos dinámicos que las diferencian de aquellas con impulsos a tiempos fijos son ejemplificados, ...
-
(2012)A new epidemic model of seasonal/cyclical pulse contagions of an infectious disease is introduced: a population with a controlled infectious disease is perturbed by a sequence of pulse infectious events arising from the ...

(World Scientific Publ, 2015)This note gives an overview on basic mathematical models describing the population dynamics of a single species whose vital dynamics has different time scales. We present five cases combining two time-scales with Malthusian ...
-
(2011)The dynamics of four source-sink models for an exploited resource under a constant fishing effort are here presented. Two models are described by ordinary differential equations; the other two are expressed by impulsive ...

(John Wiley, 2014)A self-cycling fermenter is a batch fermenter subject to recurrent emptyings of liquid volume followed by the refillingwith new fresh substrate. This article constructs amodified model of self-cycling fermenter, which is ...
