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 ...

Household Appliance Classification Using Lower Odd-Numbered Harmonics and the Bagging Decision Tree
IEEE Access, 2020 Non-Intrusive Load Monitoring (NILM) systems have gained popularity in recent years for saving more energy. To reduce sensing infrastructure costs, NILM monitors the electrical loads based on a machine learning method.

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).
