The parameters the mean and the variance of R-R interval signal plays an important role and can be utilized for the classification along with the power content in low and high frequency bands [10].
The interval signal used for decades on Deutsche Welle's radio programs was borrowed from an aria in "Fidelio."
The Lincolnshire Poacher is the nickname of a mysterious, powerful shortwave numbers station that uses two bars from its namesake English folk song tune as an interval signal. The station is believed to be operated by the British Secret Intelligence Service and emanates from the Royal Air Force base at Akrotiri -- but nobody knows what the strange code means.
More crude chanting followed and Allback's second goal just four minutes after the interval signal led a more sustained and vociferous show of displeasure from the stands.
where [a.sub.k] [member of] R" denotes the kth analyzed vibration acceleration signals, n means the length of analyzed signal, [d.sub.m] [member of] [R.sup.p] denotes a set of atoms, p is the length of atom, * means the convolution operation, [x.sub.k,m] [member of] sparse coefficients related to given signal [s.sub.k] and atom [d.sub.m], K is the number of interval signals [s.sub.k], M is the number of atoms [d.sub.m], and [lambda] [member of] [R.sup.+] means penalty parameter which determines the sparse characteristic.
Given the analyzed signals a, the interval signals [a.sub.k] [member of] [R.sup.n](k = 1,2, ..., K) are obtained so that a = [[a.sub.1.sup.T], [a.sub.K.sup.T]r e RnK (n = 1024, K =8 in this paper).
In Figure 1, the atoms dm are learned from the interval signals [a.sub.k] [member of] [R.sup.n](k = 1,2, ..., K) through the interleaved iterations of SISC and SIDL of CSR to enhance the learning efficiency.
To apply C-FuzzyEn on the gait stride interval signals for the analysis of gait symmetry, there were three parameters to be set up.
The results of applying C-FuzzyEn(1,2, r, 150) on the left and right stride interval signals are shown in Figure 5, and the results of C-SampleEn(1, r, 150) are displayed in the same figure as a comparison.
A 7-second interval signaled heat that caused mild pain, a 15-second wait heralded heat that produced moderate pain, and a 30-second gap indicated heat resulting in pronounced pain.
Examples of the former appear in what Ligeti calls "interval signals," which began to emerge in his work during the mid 1960s.
