The average collapse frequency in MEB is much higher than the bubble departure frequency in nucleate boiling, greatly enhancing the heat transfer process.
Experiments were carried out on the sound pressure oscillations condensation regime map, and bubble collapse frequency during the direct contact condensation of vapor with the aid of an acoustic hydrophone and a high-speed video camera.
Furthermore, the bubble collapse frequency increased with increase in liquid subcooling and vapor injection rate, and could be obtained from the spectral and Hurst analyses of the signals indirectly.
Additional measures to increase computational speed included data collapsing, frequency weights, and matrices with previous beta coefficients used as priors.
"At the time when the grid collapsed, the frequency was 50.2 hertz," he said, which is normal.
The magnitude of the Sleep vs. Wake difference for unique vs. shared features was not different, collapsing across frequency (t = 0.303, p = 0.763).
Notably, there was a reliable above-baseline improvement in shared feature memory in the Sleep group, collapsing across frequency (Fig. 2; t = 2.093, p = 0.041; after FDR correction across three feature types, p = 0.122).
The Wake group had reliable forgetting of both unique and shared features, collapsing across frequency (unique: t = 4.109, p = 0.0002, FDR-corrected p = 0.0004; shared: t = 2.482, p = 0.017, FDR-corrected p = 0.026).
Including subjects who napped in the Wake group might have been expected to reduce the magnitude of the effects, but Cohen's d values were slightly stronger (more negative) for unique (nap d = −0.564, no nap d = −0.356) and shared features (nap d = −0.310, no nap d = −0.182) in the group that napped, collapsing across frequency (for novel item features, nap d = 0.140, no nap d = 0.075).
The monkey data were analyzed in a similar way as the human data, except that we collapsed multiple frequency conditions into a binary, low versus high, classification problem (with a chance level of 50%).
As we take the real part of the complex cross time-frequency distribution, the joint moment will collapse to instantaneous frequency and group delay in traditional auto time-frequency analysis if the signal pair and are identical.
