11Density functional theory — Electronic structure methods Tight binding Nearly free electron model Hartree–Fock method Modern valence bond Generalized valence bond Møller–Plesset perturbation theory …
12Density-dependent inhibition — In population ecology, density dependent inhibition describes a situation in which population growth is curtailed by crowding, predators and competition. In cell biology, it describes the reduction in cell division. When a cell population reaches …
13Theoretical gravity — In geodesy and geophysics, theoretical gravity is a means to compare the true gravity on the Earth s surface with a physically smoothed model. The most common model of a smoothed Earth is the Earth ellipsoid. Despite of the fact that the exact… …
14Density matrix renormalization group — The density matrix renormalization group (DMRG) is a numerical variational technique devised to obtain the low energy physics of quantum many body systems with high accuracy. It was invented in 1992 by Steven R. White and it is nowadays the most… …
15theoretical probability — noun the probability that a certain outcome will occur, as determined through reasoning or calculation. , Given a die which is a regular octahedron of uniform density, and given that one and only one of its faces is painted black, then if the die …
16Energy density — For energy density in the sense of energy per unit mass, see specific energy. For energy density of foods, see specific energy. Energy density is a term used for the amount of energy stored in a given system or region of space per unit volume.… …
17Low-density parity-check code — In information theory, a low density parity check code (LDPC code) is an error correcting code, a method of transmitting a message over a noisy transmission channel. [David J.C. MacKay (2003) Information theory, inference and learning algorithms …
18Current density — This page is about the electric current density in electromagnetism. For the probability current density in quantum mechanics, see Probability current. Current density is a measure of the density of flow of a conserved charge. Usually the charge… …
19Linear low-density polyethylene — (LLDPE) is a substantially linear polymer (polyethylene), with significant numbers of short branches, commonly made by copolymerization of ethylene with longer chain olefins. Linear low density polyethylene differs structurally from conventional… …
20Amsterdam Density Functional — (ADF) is a program for first principles electronic structure calculations that makes use of density functional theory. [ Computational Chemistry , David Young, Wiley Interscience, 2001. Appendix A. A.2.1 pg 332, ADF ] ADF was first developed in… …
