Spatiotemporal phase-matching in capillary high-harmonic generation [PDF]
, 2012 We present a simple phase-matching model that takes into account the full spatiotemporal nature of capillary high-harmonic generation. Spectra predicted from the model are compared to experimental results for a number of gases and are shown to reproduce ...

P-class phasor measurement unit algorithms using adaptive filtering to enhance accuracy at off-nominal frequencies [PDF]
, 2011 While the present standard C.37.118-2005 for Phasor Measurement Units (PMUs) requires testing only at steady-state conditions, proposed new versions of the standard require much more stringent testing, involving frequency ramps and off-nominal frequency ...

Detection of Mistuning in Harmonic Complex Tones at High Frequencies
Acta Acustica united with Acustica, 2018 Lau et al. [1] showed that listeners could discriminate differences in the fundamental frequency (F0) of harmonic complex tones containing only very high frequency components, even though the discriminability of those components, when presented alone, was very poor. They attributed this finding to the operation of central pitch-sensitive neurons.

Bispectrum of stator phase current for fault detection of induction motor [PDF]
, 2009 A number of research studies has shown that faults in a stator or rotor generally show sideband frequencies around the mains frequency (50 Hz) and at higher harmonics in the spectrum of the Motor Current Signature Analysis (MCSA).
