self-excite

present singular third person self-excites · participle present self-exciting · participle past self-excited · past self-excited

1. To energize or excite (the field magnets of a dynamo) by induction from the residual magnetism of its cores, leading all or a part of the current thus produced through the field-magnet coils.

   This so-called "field flashing" reestablishes the residual magnetism to allow the generator to self-excite.

   Using metal rollers to simulate the earth's cylindrical eddy currents, the team found some interesting results after beginning with a few viscosity problems. "...a more efficient geometry was found, so efficient that the dynamo would self-excite in a completely homogeneous state (i.e. with no insulation ) at a much lower rotor speed than was believed possible" [12] .

   The induction generator can self-excite using the external capacitor only if the rotor has an adequate remnant magnetic field.

2. To self-generate a state of excitation.

   When both neurons self-excite themselves and have the same mutual interaction pattern, the mechanism of creation of a new attractive fixed point is shown to be that of saddle node bifurcation.

   Thus warning systems can self-excite when they go on alert: When a decision maker thinks that an attack is likely, he will place more credence in reports indicating that a war is imminent than he would if the same information were received in a period of calm, and actions of the other side that usually would be missed or seen as innocent will be perceived as evincing hostile intentions.

   In a subsequent revision of the RI hypothesis, mutually excitatory interactions between cholinergic and glutamatergic neurons underlie the rapidly escalating firing of pontine reticular REM-on neurons during REM sleep and cholinergic REM-on cells both self-excite and self-inhibit via cholinergic autoreceptors.
