If the hum goes a little flat, that indicates too much demand on the grid, so whenever a controller notices the American standard 60Hz grid frequency dipping to 59.95Hz (something that usually happens at least once a day) it shuts off the heating element in the appliance it is regulating for two minutes.
This improvement can be explained by the fact that spectral combining equalizes frequency dips that occur only in one microphone input (cf. Figure 3).
However, a consistency in the frequency dips observed among monocots and dicots suggests a class specific mode of gene regulation.
The result indicated that the stiffened diaphragm improved the smoothness of the sound pressure curve for the speaker, which produced a mid-frequency dip difference (ΔdB) of 1.9 dB and an attenuation peak frequency (fpeak) of 4220 Hz.
Measured values of transmission loss differ from the 2-D model by the wide low-frequency dip of the mass spring mass or "msm" resonance also termed the "air gap resonance".
A higher frequency of DIP joint changes was found by US in the PsA patients compared with RA patients.
Among the remaining DIPs, sign of GSVs of frequency domain DIPs is checked to classify the probable defect.
The second interpretation of the initial drop in head-dipping frequency is that head-dipping could represent a fearful, neophobic response, such that, on first exposure to the apparatus, the animal actively attempts to find an escape route (Renner, 1990).
We found that the dip frequency shift, transmittance attenuation of the dip frequency, and peak shift of the derivative spectrum of the phase shift depend on the bonding amount of lectin sugar interactions.
A seismic attribute is a measurable property of seismic data, such as amplitude, dip, frequency, phase, and polarity that facilitates seismic data comprehension and interpretation.
