Control and switching synchronization of fractional order chaotic systems using active control technique

2014Hashim I.JournalMoaddy K.Momani S.Radwan A.G.Salama K.N.

This paper discusses the continuous effect of the fractional order parameter of the Lü system where the system response starts stable, passing by chaotic behavior then reaching periodic response as the fractional-order increases

The fractional-order modeling and synchronization of electrically coupled neuron systems

2012Hashim I.JournalMoaddy K.Momani S.Radwan A.G.Salama K.N.

In this paper, we generalize the integer-order cable model of the neuron system into the fractional-order domain, where the long memory dependence of the fractional derivative can be a better fit for the neuron response
