Mean free time — Molecules in a fluid constantly collide off each other. The mean free time of a molecule in a fluid is the average time between collisions. The mean free path of the molecule is the product of the average speed and the mean free time. These… … Wikipedia
Radiative transfer equation and diffusion theory for photon transport in biological tissue — Photon transport in biological tissue can be equivalently modeled numerically with Monte Carlo simulations or analytically by the radiative transfer equation (RTE). However, the RTE is difficult to solve without introducing approximations. A… … Wikipedia
Ballistic transport — is the transport of electrons in a medium with negligible electrical resistivity due to scattering. Without scattering, electrons simply obey Newton s second law of motion at non relativistic speeds.In general the resistivity exists because an… … Wikipedia
Monte Carlo methods for electron transport — The Monte Carlo method for electron transport is a semiclassical Monte Carlo(MC) approach of modeling semiconductor transport. Assuming the carrier motion consists of free flights interrupted by scattering mechanisms, a computer is utilized to… … Wikipedia
Diffusing-wave spectroscopy — (DWS) is an optical technique derived from dynamic light scattering (DLS) that studies the dynamics of scattered light in the limit of strong multiple scattering.[1][2] It has been widely used in the past to study colloidal suspensions, emulsions … Wikipedia
