On a simple derivation of the very low damping escape rate for classical spins by modifying the method of Kramers
Declan J. Byrne, William T. Coffey, Yuri P. Kalmykov +1
The original perturbative Kramers' method (starting from the phase space coordinates) (Kramers, 1940) of determining the energy-controlled-diffusion equation for Newtonian particle…
Comparison of coupled nonlinear oscillator models for the transient response of power generating stations connected to low inertia systems
Marios Zarifakis, Declan J. Byrne, William T. Coffey +3
Coupled nonlinear oscillators, e.g., Kuramoto models, are commonly used to analyze electrical power systems. The cage model from statistical mechanics has also been used to describ…
Active Damping of Power Oscillations Following Frequency Changes in Low Inertia Power Systems
Marios Zarifakis, William T. Coffey, Yuri P. Kalmykov +3
The absolute requirement to increase the amount of energy generation from renewable sources e.g. predominantly asynchronously connected wind turbines and photovoltaic installations…
On a boundary value problem of a singular discrete time system with a singular pencil
Ioannis K. Dassios
In this article, we study a boundary value problem of a class of singular linear discrete time systems whose coefficients are non-square constant matrices or square with a matrix p…
