depends on the modal function sign at the receiver depth. is a phase factor at frequency linked to the propagation distance between source and receiver.
In the following, we consider b = t the translation applied to each t time point, and the frequency linked to the scale parameter α, ; thus C s (f, t) ≈ C s (a, b).
At high speed with field weakening operation, iron losses, sensitive to flux densities variation in iron, could be really high because of the high electrical frequency linked to rotor speed and sharp variation of flux density waveforms inside the iron in stator due to the field weakening operation.
For convenience's sake, this information is mapped onto a frequency vector, linked to the partition.
This is demonstrated via recent research in the Ouachita Mountains, Arkansas, where changes in selective pressures on trees associated with fire frequency are linked to changes in soil morphology.
Spatial frequency is linked to variance in 3D discrete curvature, and studies have used this curvature as a 3D perceptual measure [24], [29].
As such their frequency is linked to the mass of the compact object.
In rodents, these changes can be either abrupt, sustained changes so-called on-off responses—or gradual frequenchanges so-called to the velocity of responses orta et al., 2004).
Subsequent studies using cpYFP-based probes indicated that flash frequency is linked to mitochondrial respiration (Pouvreau, 2010; Wei et al, 2011) and increases during oxidative stress-induced apoptosis (Ma et al, 2011), reviewed in Fang et al (2011).
The majority of studies relating electrophysiological brain signals to hemodynamics support the notion of a systematic relation between frequency and direction of the BOLD signal, in the sense that lower frequencies are coupled to BOLD signal decreases, whereas higher frequencies are linked to BOLD signal increases.
The researchers, who reported their findings in Current Biology, suggest that the mid-range frequencies are linked to the perception of visual information, while the high-frequency activity may be related to cognitive processing — perhaps the recognition of a landmark as something the bird has seen before.
