In this and the following sections, we use lower-case letters to represent small-amplitude perturbation variables, and we mainly discuss the fluid and solid motion with nondimensional variables, taking α 0 ∗, a∗, a ∗ / α 0 ∗, and ρ 0 ∗ α 0 ∗ 2 as the units of velocity, length, time, and pressure, respectively.
By determining the parallax of a star, the proper motion can then be converted into units of velocity.
This suggestion is confirmed with dimensional analysis [ 23] by noting that "generation" is a discrete time-like dimension, and that the relations nLadv and n0.5Ldiff suggest underlying parameters with units of velocity (time/distance) and diffusivity (distance/time).
In most gear calculations, this is given in rotations per minute (rpm), though other units of velocity will also work.
These values are shown in the unit of wind velocity by considering the amount of wind velocity change for the r2 distance corresponding to one free spectral range.
Microsaccades were then located using the same algorithm [66] (velocity threshold = 10 std.; minimum duration = 4 units of time; velocity type = 2; Note that we used a higher velocity threshold than what was used in [67] to identify eyeblinks and large eye movements. After removing these eyeblinks and large eye movements, we applied the same algorithm again to identify microsaccades).
Eyeblinks and huge eye movements were then identified by the algorithm of Engbert and Kliegl [21] (velocity threshold = 10 std.; minimum duration = 5 units of time; velocity type = 2; amplitude bigger than 3.33 visual degrees).

Under (a) AC and (b) ZZ strains in a unit of the Fermi velocity without strain (v0), respectively.
The ion velocity V is normalized in units of ion thermal velocity (V_{text{ ti }}=left( T_{text{i}}/m_{text{i}}right) ^{1/2}) and velocity distribution function f is normalized by (V_{text{ ti }}/n_{text{ i0 }}).
