In the slab limit, one can show ωH = k kr mi me Ωci . (6.2) This mode is physically pathological, because the frequency increases indefinitely as me decreases, and also as kr decreases – that is, as the radial box size grows. While nonzero β provides a cutoff, the stable ...
in [58] proposed a stand-alone heart beat detection which uses axis selection, band-pass filtering, artifact removal, beat detection based on the envelope of the squared signal, k-means clustering of the detected local maxima and minima, and finally merging beat locations from four independent ...
