We shall derive the equations for the positive half cycle of the grid voltage.
It can be seen that on each half cycle, opposite pairs of diodes conduct, but the current through the load remains in the same polarity for both half cycles.
A biological indicator is placed in each of these locations and tested separately after the half cycle.
A reduced requalification was generally a single half cycle to verify the process still delivered an SAL of 10-6.
HIF model of Figure 5 including a nonlinear resistance two diodes and two DC sources with amplitudes which change in every half cycle randomly has been presented in 2004.
In the interfacial polarization mechanism, only charge carriers with high drift velocity got enough time to pile up at the interfaces in each half cycle of alternating electric field.
For ideal piston flows, if the required ACH is infinitely high and the air supply and exhaust locations can be exchanged at the end of each half hour, the CO ppm rise distribution in the first half hour would be the same as that in Figure 1 and it would be reversed in the second half hour, as shown in Figure 1 Half hour half cycle or 1 h a full cycle chosen here corresponds to the half hour and 1 h CO ppm rise criteria in the Australian standard AS 1668.

The third descending half cycle meant a long period favorable for gold beginning in 1999, which could be projected until the middle or even latter part of the 2011-2020 decade.
The leftward motion ends in the top left corner with a final upward half cycle, shown in green.
These industrial circuit breakers are current limiting, which means they interrupt fault currents within one half cycle of the fault.
