An analytical model of the Aeolian vibrations of a conductor is proposed, based on the theory of narrow frequency bands of random noise.
The most important advantage of the design is that the damper can be tuned for a large reduction of the vibration in a narrow frequency range of choice while providing damping in a broad range of frequency as well.
This ensures that the returning echo falls within the narrow frequency range of their acoustic fovea a region of the cochlea with sharply tuned neurons sensitive to a unique frequency called the reference frequency [ 56].
The narrow frequency band of the source provides for greater energy selectivity of the upper state that is being populated.
In PA neurons, activity evoked by the broad frequency range of high intensity stimuli persisted and overlapped with responses to the narrow frequency range of near-CF tones.
The reduction in phase-specific beta amplitude modulation following treatment of Parkinson's disease patients with levodopa suggests that the pathologically narrow frequency tuning of the basal ganglia network in Parkinson's disease is broadened by dopaminergic input.
The former caused large response in a narrow frequency range of 0.015 0.09 Hz, while the latter resulted in large response in a wider frequency range from 0.06 to 0.6 Hz.
Until now, most ultrasonic speakers have utilized piezoelectric buzzer-like radial mode transducers, which necessitates a complicated signal processing circuit to overcome the narrow frequency bandwidth of the transducers.
The spectrum for a narrow frequency band of f Hz is defined as, (2 with where e denotes eigenvectors in the noise subspace, and a: is the array response function, and where the superscript H indicates a Hermitian matrix, L is number of signals comprising the waveform, and x i is the positioning vector of the i-th sensor.
Motivated by the existence of relatively short-lived, eastward- and westward-moving disturbances within the MJO complex, the MJO has been thought as a wave packet the interference pattern produced by a narrow frequency band of mixed Rossby-gravity (Yang and Ingersoll 2011) or inertia gravity waves (Yang and Ingersoll 2013, 2014).
