Therefore, this patient might have diagnosis of either EPH with fluctuating frequency, CH with fluctuating frequency or a combination of both EPH and ECH.
An estimate of the solar wind convection velocity is obtained from a combination of the frequency (Doppler) fluctuation spectral power at low fluctuating frequency and the power in the flat part of the intensity scintillation spectra below the Fresnel frequency.
Magnetic flux noise in the SQUID loop may lead to a fluctuating resonance frequency and thus a fluctuating effective gain.
The particle fluctuating frequency, the dispersion coefficient, and the correlation dimension of pressure fluctuations have been correlated with the length and velocity scales of the microeddies in the bed based on the isotropic turbulence theory.
Both fluctuating frequency and dispersion coefficient of particles increased with decrease in surface tension of liquid phase, due to the increase of bubbling phenomena with decrease in σL.
The two values of fluctuating frequency and dispersion coefficient of particles increased with increase in particle size, but decreased with increase in liquid viscosity due to the restricted movement and motion of particles in the viscous liquid medium.
The disadvantages of the method are its poor performance in the case of fluctuating frequency and unbalanced grid voltage [15].
The interference between two electric fields with Doppler frequency difference will generate a fluctuating AC signal, whose frequency is equivalent to the Doppler frequency difference.
According to atomic force microscopy data, we suggest that the substrate, fluctuate amplitude and fluctuate frequency of roughness on ZnO seed layers have a great impact on the alignment of the resulting NWs, whereas the influence of the seed layers' texture was negligible.
Although the buckling pressure fluctuates, because the fluctuation frequency is high, it does not have any pronounced influence on the drop-mass velocity, as shown in Fig. 3b.
We further decompose the sensitive component into mono-component intrinsic mode functions (IMFs) to estimate their instantaneous frequencies, and select a sensitive IMF with an instantaneous frequency fluctuating around the center frequency for frequency demodulation analysis.
