Damping of gravitational waves by matter
We develop a unified description, via the Boltzmann equation, of damping of gravitational waves by matter, incorporating collisions. We identify two physically distinct damping mechanisms -- collisional and Landau damping.

Enhanced gilbert damping in thin ferromagnetic films. [PDF]
The precession of the magnetization of a ferromagnet is shown to transfer spins into adjacent normal metal layers. This "pumping" of spins slows down the precession corresponding to an enhanced Gilbert damping constant in the Landau-Lifshitz equation ...

Dynamical depinning of chiral domain walls [PDF]
The domain wall depinning field represents the minimum magnetic field needed to move a domain wall, typically pinned by samples' disorder or patterned constrictions.

Determining Vibration Frequency and Damping of Metal Beams Using Image Processing Method [PDF]
In the present study, damping and frequency of two beams, including galvanized and steel beams, were evaluated using the image processing method. The beam supports were designed as a hinge and the intended beam was vibrated through displacements. the FFT

On the robustness of the average power ratios in damping estimation: application in the structural health monitoring of composites beams [PDF]
In composites structures, cracking, delamination will cause changes in the measured dynamic response of structure and so on experimentally modal parameters.
