exponential diffusion
1exponential diffusion — /ekspəˌnenʃ(ə)l dɪ fju:ʒ(ə)n/, exponential growth /ekspəˌnenʃ(ə)l grəυθ/ noun a typical growth pattern of new products that involves a slow start, followed by acceleration and finally a slowing down …
2diffusion curve — /dɪ fju:ʒ(ə)n k :v/ noun the geographical representation of how many consumers adopt a product at different times. ⇒ exponential diffusion …
3Stretched exponential function — Figure 1. Illustration of a stretched exponential fit (with β=0.52) to an empirical master curve. For comparison, a least squares single and a double exponential fit are also shown. The data are rotational anisotropy of anthracene in… …
4Radiative 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… …
5Bass diffusion model — The Bass diffusion model was developed by Frank Bass and describes the process how new products get adopted as an interaction between users and potential users. The model is widely used in forecasting, especially product forecasting and… …
6Path integral formulation — This article is about a formulation of quantum mechanics. For integrals along a path, also known as line or contour integrals, see line integral. The path integral formulation of quantum mechanics is a description of quantum theory which… …
7Nuclear magnetic resonance in porous media — Nuclear magnetic resonance (NMR) in porous media covers the application of using NMR as a tool to study the structure of porous media and various processes occurring in them.[1] This technique allows the determination of characteristics such as… …
8electrochemical reaction — ▪ chemistry Introduction any process either caused or accompanied by the passage of an electric current and involving in most cases the transfer of electrons between two substances one a solid and the other a liquid. Under ordinary… …
9Normal distribution — This article is about the univariate normal distribution. For normally distributed vectors, see Multivariate normal distribution. Probability density function The red line is the standard normal distribution Cumulative distribution function …
10Marcus theory — is a theory originally developed by Rudolph A. Marcus, starting in 1956, to explain the rates of electron transfer reactions – the rate at which an electron can move or jump from one chemical species (called the electron donor) to another (called …
