The restraint, like the previous in this section, allows for the removal of acoustic waves, but also allows for large perturbations in density and/or temperature.
The perturbations of 300 asteroids were included, vs DE118/DE200 which included only the five asteroids determined to cause the largest perturbations.
Because the states have resilience, following small perturbations (e.g., changes to population size) the community returns to the same configuration while large perturbations may induce a shift to another configuration.
The largest geomagnetic perturbation, resulting presumably from a "prehistoric" CME, coincided with the first-observed solar flare, in 1859.
In the second two cases, simulations require unrealistically large perturbations to cause the changes that actually occurred in the past.
Several of the largest lunar perturbations in longitude (contributions to the difference in its true ecliptic longitude relative to its mean longitude) have been named.
This causes large perturbations of both, with a period of 918 years, the time required for the small difference in their positions at conjunction to make one complete circle, first discovered by Laplace.
French PWRs use "grey" control rods, in order to replace chemical shim, without introducing a large perturbation of the power distribution.
As the Hubble radius grows in the expanding Universe, it encompasses larger and larger perturbations.
This means that when small perturbations occur, the state is still stable; however when larger perturbations occur, the traffic is unstable and moving jams will emerge.
