The transmit antennas simultaneously emit orthogonal waveforms S = [[[s.sup.T.sub.1], ..., [s.sup.T.sub.M]].sup.T] [member of] [C.sup.MxL] where L is the number of samples during pulse period
. Assume that there are K uncorrelated narrowband far-field source signals in the range bin of interest.
Based on a study of the effects from rupture directivity on ground motion attenuation relationships, the pulse period
increases with earthquake magnitude, a parameter related to fault dimensions and source parameters (Somerville, 2003).
XFSEARCH searches for the pulse period
and its derivatives from the corrected photon arrival times in the time domain as well as the frequency domain [16, 17], and it will update the nominal database's pulsar parameters if necessary.
where x and y are densities of the prey and predator populations at time t, respectively; r denotes the intrinsic growth rate of prey; K represents the environmental capacity of prey; d is the death rate of the predator; ax(t)/(1 + wx(t)) is the Holling type 2 functional response; c/a is the rate of conversing prey into predator; T is the pulse period
;[sigma] is the release amount of predator at time points t = nT.
The change of heart rate means the change of pulse period
. The pulse wave velocity remains constant in spite of the change of pulse period
The triangle shaped inductance currents of the two phases are shifted with about a half pulse period
. At switched-on time the input current of each phase is twice as small as the inductance current from a single-phase converter.
To investigate the complex dynamics that model (4) can have, we chose the pulse period
T as a bifurcation parameter and fixed all other parameters as those in Figure 4 for two different [theta] values.
It is known that echoes corresponding to the transmitted pulse can be received at least one pulse period
The current is sampled twice in each pulse period
(once before the potential step, and then again just at the end of the pulse).
Following the addition of the bacteria to the N-pulse tank and the bicarbonate to the C-pulse tank, the aquaria were held out of the water for 9 h (the pulse period
) and then re-submerged for one week (the chase period).
The required flow during the pulse period
is automatically controlled via an 8-bit digital interface by a PLC or other external controller.
can be set between 2,000 seconds and 80 ns (0.5 mHz to 12.5 MHz), and the duty cycle can be as low as one in two billion.
