Reliable compartmental models for double-pipe heat exchangers: An analytical study
(2007)"In this work, the analytical properties of the heat exchanger infinite-dimensional dynamic model are discussed. More importantly, those of a 2nd-order lumped-parameter model using the logarithmic mean temperature difference ... -
Pseudo-random bit generator based on lag time series
(2014)"In this paper, we present a pseudo-random bit generator (PRBG) based on two lag time series of the logistic map using positive and negative values in the bifurcation parameter. In order to hidden the map used to build the ... -
Activation of neuronal ensembles via controlled synchronization
(2017)"In this contribution we present the activation of neuronal ensembles of Hindmarsh-Rose neurons by controlled synchronization. The main problem consists in to impose a particular spiking-bursting behavior in all the neurons ... -

On the controllability of networks with nonidentical linear nodes
(Oxford University Press, 2016)"The controllability of dynamical networks depends on both network structure and node dynamics. For networks of linearly coupled linear dynamical systems the controllability of the network can be determined using the ... -
