The diamagnetic drift is not actually a guiding center drift and resembles averaged (fluid) behavior of large collection of particles. A pressure gradient does not cause any single particle to drift. Nevertheless, the fluid velocity is defined by counting the particles moving through a reference area, and a pressure gradient results in more ...
Inbound aircraft to London Heathrow Airport typically follow one of a number of Standard Arrival Routes (STARs The STARs each terminate at one of four different RNAV waypoints (co-located with VOR navigational aids), and these also define four "stacks" [1] where aircraft can be held, if necessary, until they are cleared to begin their approach to land.
Limits of Stability (LoS) is a significant variable in assessing stability and voluntary motor control [6] in dynamic states. [7] It provides valuable information by tracking the instantaneous change in the center of mass (COM) velocity and position. [7]
v d is the magnitude of the electron drift velocity (in other words, the electron drift speed) caused by the electric field, and; μ e is the electron mobility. The hole mobility is defined by a similar equation: =. Both electron and hole mobilities are positive by definition.
Because the Earth rotates (ω, 15° per hour, apparent drift), and because of small accumulated errors caused by imperfect balancing of the gyro, the heading indicator will drift over time (real drift), and must be reset using a magnetic compass periodically.
Drift is often subdivided into unstratified (unsorted) drift (glacial till) that forms moraines and stratified drift (glaciolacustrine and fluvioglacial sediments) that accumulates as stratified and sorted sediments in the form of outwash plains, eskers, kames, varves, and so forth. The term drift clay is a synonym for boulder clay. Both are ...
For the simulation generating the realizations, see below. A geometric Brownian motion (GBM) (also known as exponential Brownian motion) is a continuous-time stochastic process in which the logarithm of the randomly varying quantity follows a Brownian motion (also called a Wiener process) with drift.

The Stokes drift is the difference in end positions, after a predefined amount of time (usually one wave period), as derived from a description in the Lagrangian and Eulerian coordinates. The end position in the Lagrangian description is obtained by following a specific fluid parcel during the time interval.
