Astronomers have detected transient rhythmic oscillations in the gamma-ray emission from the blazar Markarian 501. The discovery, reported in a paper published August 18 on the arXiv pre-print ...

Sometimes called ring wave transients, this type of disturbance has a fast rise time, oscillations that decay exponentially, and lower energy content than impulse transients (250V to 2,500V). A ...

The natural frequency is determined by spring stiffness K and inertia J as follows: The damping ratio is a dimensionless number that reflects how rapidly transient oscillations decay. The ...

since the strong nonlinear couplings between the various components may cause instability issues during transient operations. One example issue that is commonly encountered is EXV hunting and ...

With FAST's high sampling and sensitivity, the research team detected two instances of transient periodic oscillation of about 0.2 seconds in January 2021 and June 2022, respectively. The ...

Figs. 6a to 6c show output voltage with a load transient. While enough ripple to prevent limited cycle oscillation is injected in all cases, Fig. 6c limits oscillation, undershoot/overshoot due to ...
