Automated nasal feature detection for the lexical access from features project
… cues included observing the presence of a low frequency resonance in the short-time spectra, stability in the signal energy, and characteristic spectral tilt. The acoustic cues for the nasal boundary measured the change in the energy of the first harmonic and the net energy change of the …

An ultrasonic study of hydroxyl ion in single crystals of rubidium chloride
… OH ions were made as a function of polarization, frequency, concentration and temperature from 0.6 K to 24 K. A rise in absorption of the low frequency (10 to 70 MHz) Cmode sound waves has been observed at low temperll atures. A similar anomalous absorption has been observed in other defect …

Low-Frequency Series Loaded Resonant Inverter Characterization
… mainly attributed to a load dependent resonant frequency. Recent advancements in power electronics propose an electronically tunable inductor suited for low frequency applications [24], [25]; as a consequence, frequency stability in resonant inverters is achievable within a limited load range. …
