Stochastic Hierarchical Systems: Excitable Dynamics [PDF]
Journal of Biological Physics, 2008 We present a discrete model of stochastic excitability by a low-dimensional set of delayed integral equations governing the probability in the rest state, the excited state, and the refractory state. The process is a random walk with discrete states and nonexponential waiting time distributions, which lead to the incorporation of memory kernels in the ...

Modeling excitable systems: Reentrant tachycardia [PDF]
American Journal of Physics, 2009 Excitable membranes are an important type of nonlinear dynamical system, and their study can be used to provide a connection between physical and biological circuits. We discuss two models of excitable membranes important in cardiac and neural tissues.

Skyrmion excitations in quantum Hall systems [PDF]
Physical Review B, 1996 Using finite size calculations on the surface of a sphere we study the topological (skyrmion) excitation in quantum Hall system with spin degree of freedom at filling factors around $ =1$. In the absence of Zeeman energy, we find, in systems with one quasi-particle or one quasi-hole, the lowest energy band consists of states with $L=S$, where $L$ and $

Response of a Parametrically Excited System to a Nonstationary Excitation [PDF]
Journal of Vibration and Control, 1993 The response of a single-degree-of-freedom system to a nonstationary excitation is investigated by using the method of multiple scales as well as analog- and digital-computer simulations. The unexcited system has one focus and two saddle points. The system can be used to model rolling of ships in head or follower seas. The method of multiple scales is

Coordination between loss of excitation protection and minimum excitation limit function of voltage regulation system [PDF]
Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2021 Established practice is such that the relay protection system and excitation system are adjusted independently of each other, which very often leads to non-coordinated action.
