The brownian motion
網頁Brownian motion with drift So far we considered a Brownian motion which is characterized by zero mean and some variance parameter σ 2. The standard Brownian … 網頁2007年8月29日 · We illustrate these phenomena by considering the quasi-two-dimensional Brownian motion of an ellipsoidal rigid particle in linear and harmonic potential fields. These two examples provide insight into the role played by particle asymmetry in electrophoresis and microconfinement due to a laser trap or due to intracellular …
