Design of asynchronous supervisors [PDF]

open access: yes, 2009
One of the main drawbacks while implementing the interaction between a plant and a supervisor, synthesised by the supervisory control theory of \citeauthor{RW:1987}, is the inexact synchronisation.

Asynchronized Synchronous Machines [PDF]

open access: yesElectronics and Power, 1964
This book provides a theoretical treatment of the operation, and the excitation systems, of “asynchronized” synchronized (AS) machines — that is, ac motors and generators which have their excitation supplied by an independent slip-frequency source. Such devices are usually called “doubly fed” machines in American practice.

Transient Information Flow in a Network of Excitatory and Inhibitory Model Neurons: Role of Noise and Signal Autocorrelation [PDF]

open access: yes, 2004
We investigate the performance of sparsely-connected networks of integrate-and-fire neurons for ultra-short term information processing. We exploit the fact that the population activity of networks with balanced excitation and inhibition can switch from ...
