Self-pulsation
Self-pulsation is a transient phenomenon in continuous-wave lasers. Self-pulsation takes place at the beginning of laser action. Steady-state solution Weak pulsation Decay of small pulsation occurs with rate where Practically, this rate can be orders of magnitude smaller than wikipedia.org

Brake Pedal Pulsation While Braking: a Common Culprit - Testing Autos
Dec 3, 2023Drums can also be resurfaced or replaced. Car makers specify the maximum allowable brake drum diameter. If it's worn close to the maximum diameter, the drum must be replaced. Address minor rust spots by driving the car regularly, allowing the friction from braking to remove surface rust. If severe, consult a professional for evaluation.

Rapidly oscillating Ap star
In this model the axis of pulsation is aligned with the magnetic axis, which can lead to modulation of the amplitude of the pulsation, depending on the No standard pulsation model can be made to excite oscillations of the roAp type using the opacity mechanism. wikipedia.org

How do the Laplace s-domain and the complex frequency domain differ? In systems theory and signal processing, we often transform expressions based in the Laplace $s$-domain into the complex frequency domain with $j\om...
The Laplace transform turns linear differential equations into algebraic ones. Multiplication by $s$ is the operation corresponding to differentiation wrt to $t$ in the other domain. Maybe you should think of it as an operator, not a quantity like a generalized frequency. In an AC circuit, there's a...

Beta Doradus
During each radial pulsation cycle, the radius of the star varies by ±3.9 times the Sun's radius around a mean of 67.8. The X-ray luminosity is about 1 × 1029 erg/s and the emission varies with the pulsation period, suggesting a connection with the pulsation process. wikipedia.org
