Modeling pulse infectious events irrupting into a controlled context: A SIS disease with almost periodic parameters 

Robledo, Gonzalo; Cordova-Lepe, Fernando; Pinto, Manuel; González-Olivares, Eduardo (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 ...

A new class of differential equations with impulses at instants dependent on preceding pulses. Applications to management of renewable resources 

Cordova-Lepe, Fernando; Pinto, Manuel; González-Olivares, Eduardo (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: ...

A pulse fishery model with closures as function of the catch: Conditions for sustainability 

Cordova-Lepe, Fernando; Del Valle-Salamanca, Rodrigo; Robledo, Gonzalo (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 ...

A non-Newtonian gradient for contour detection in images with multiplicative noise 

Mora, Marco; Cordova-Lepe, Fernando; Del Valle-Salamanca, Rodrigo (2012)
In this paper, a new operator for contour detection in images with multiplicative noise is presented. Traditional methods of edge detection, as those based in gradient operator or measures of variance, follow a logic and ...
