How To Use Random walk In A Sentence
-
The mean square displacement of these cells compared to the fibronectin movement scales with time, indicating that cells exhibit a 'random walk'-like diffusive behaviour, with the diffusion of cells relative to the fibronectin following a posterior-to-anterior back-to-front gradient.

-
The amplification happens when each photon scatters around many times inside the powder, continually eliciting more photons as it travels on a so-called random walk.
-
To elaborate on DeWitt, an l(0) process is white noise and an l(1) process, a classical random walk ("brownian motion"). l(2) is a bit harder to describe: perhaps the location of a vehicle tracked by an inertial device, where the acceleration is "noisy".
