As t increases, the red nullcline moves cyclically between the two dashed-red lines.
The fixed point (34) moves cyclically with the same frequency between the two corresponding extreme values.
Similarly to the linear case, as t progresses, the nonlinear v-nullcline moves cyclically between the two dashed-red curves corresponding to ± A in.
As t increases N v, t "moves" cyclically, generating lines parallel to N v = − v in between the lines N v + ( v ) = − v + A in and N v − ( v ) = − v − A in. (33).
In the limit f → 0, the limit cycle trajectory moves cyclically along the w-nullcline in between the points (34) with A t = ± A in = ± 1. From (34), v max / A in = ( 1 + α ) − 1, which coincides with Z ( 0 ) in (21).
As t increases, A t changes and the v-nullcline N v, t (32) moves cyclically, parallel to itself between the lines N v + ( v ) and N v − ( v ) (33) (dashed-red lines in Fig. 4) with frequency equal to 1.
Nomadism, way of life of peoples who do not live continually in the same place but move cyclically or periodically.
As shown in Figure 6, in case that the robot is far from the handle, the robot needs to move rightward cyclically.
Originally, hunter-gatherers moved, often cyclically, over comparatively large areas.
Ms. Opie tends to work cyclically, moving from portraiture to landscape to cityscape and back again.
This approach is applied to the wear problem of a half-plane in contact with a cyclically moving indenter.
