Brownian motor — Brownian motors are nano scale or molecular devices by which thermally activated processes (chemical reactions) are controlled and used to generate directed motion in space and to do mechanical or electrical work. These tiny engines operate in an … Wikipedia
Diffusion (disambiguation) — Diffusion is a time dependent random process causing a spread in space. Diffusion may also refer to: In physical sciences Molecular diffusion, spontaneous dispersion of mass (distinct from migration, caused by an external force) Conduction of… … Wikipedia
Brownian motion — This article is about the physical phenomenon; for the stochastic process, see Wiener process. For the sports team, see Brownian Motion (Ultimate). For the mobility model, see Random walk. Brownian motion (named after the botanist Robert Brown)… … Wikipedia
Brownian motion — Any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for Robert Brown, who was investigating the fertilization process of flowers in 1827 when he noticed a rapid oscillatory… … Universalium
Diffusion — This article is about the generic concept of the time dependent random process. For other uses, see Diffusion (disambiguation). Diffusion describes the spread of particles through random motion from regions of higher concentration to regions of… … Wikipedia
Diffusion-limited aggregation — A DLA cluster grown from a copper sulfate solution in an electrodeposition cell Diffusion limited aggregation (DLA) is the process whereby particles undergoing a random walk due to Brownian motion cluster together to form aggregates of such… … Wikipedia
Brownian tree — A Brownian tree, whose name is derived from Robert Brown via Brownian motion, is a form of computer art that was briefly popular in the 1990s, when home computers started to have sufficient power to simulate Brownian motion. Brownian trees are… … Wikipedia
Diffusion process — For the marketing term, see Diffusion of innovations. In probability theory, a branch of mathematics, a diffusion process is a solution to a stochastic differential equation. It is a continuous time Markov process with continuous sample paths. A… … Wikipedia
diffusion — 1. The random movement of molecules or ions or small particles in solution or suspension under the influence of brownian (thermal) motion toward a uniform distribution throughout the available volume; the rate is relatively rapid among liquids an … Medical dictionary
Itō diffusion — In mathematics mdash; specifically, in stochastic analysis mdash; an Itō diffusion is a solution to a specific type of stochastic differential equation. Itō diffusions are named after the Japanese mathematician Kiyoshi Itō.OverviewA (time… … Wikipedia
