How the hammering process of cymbals affects their vibration characteristics

Nihon Kikai Gakkai ronbunshu, 2017
Cymbals are percussion instruments that vibrate and radiate sounds when hit with a stick or when used in pairs. The sound radiated from a cymbal depends on its vibration characteristics.

Alloying effect on the ideal tensile strength of ferromagnetic and paramagnetic bcc iron [PDF]

, 2016
Using \emph{ab initio} alloy theory formulated within the exact muffin-tin orbitals theory in combination with the coherent potential approximation, we investigate the ideal tensile strength (ITS) in the $[001]$ direction of bcc ferro-/ferrimagnetic (FFM)
