Unit commitment for systems with significant wind penetration

Tuohy, Aidan ; Meibom, Peter ; Denny, Eleanor ; O'Malley, Mark (IEEE, 2009-05)

The stochastic nature of wind alters the unit commitment and dispatch problem. By accounting for this uncertainty when scheduling the system, more robust schedules are produced, which should, on average, reduce expected ...
Wavelength-controlled variable-order optical fractional Fourier transform

Hennelly, Bryan M. ; Kelly, Damien P. ; Sheridan, John T. (Optical Society of America, 2004-03-01)

The relationship between optical fractional Fourier transforms (OFRTs) obtained at different wavelengths is derived by use of the ABCD matrix formalism. It is shown that varying the wavelength while retaining the same ...
Wigner cross-terms in sampled and other periodic signals

Rhodes, William T. ; Healy, John J. ; Sheridan, John T. (Optical Society of America, 2009-10-11)

If we sample a scalar wave field, it becomes periodic in frequency. We examine the cross-terms which occur between these periodic replicas in the Wigner-Ville distribution function of such a signal. We present analytic ...
