Density gradient — is a spatial variation in density over an area. The term is used in the natural sciences to describe varying density of matter, but can apply to any quantity whose density can be measured. [1] [2] Contents 1 Aerodynamics 2 … Wikipedia
Density wave theory — Image of spiral galaxy M81 combining data from the Hubble, Spitzer, and GALEX space telescopes. Density wave theory or the Lin Shu density wave theory is a theory proposed by C.C. Lin and Frank Shu in the mid 1960s to explain spiral arm structure … Wikipedia
Density 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… … Wikipedia

Spectral density — In statistical signal processing and physics, the spectral density, power spectral density (PSD), or energy spectral density (ESD), is a positive real function of a frequency variable associated with a stationary stochastic process, or a… … Wikipedia
Background Oriented Schlieren technique — Background Oriented Schlieren (BOS) is a novel technique for flow visualization of density gradients in fluids using the Gladstone Dale relation between density and refractive index of the fluid.BOS simplifies the visualization process by… … Wikipedia
Relative density — Relative density, sometimes called specific density, is the ratio of the density of a substance to the density of a given reference material. If a substance s relative density is less than one then it is less dense than the reference; if greater… … Wikipedia
Multivariate kernel density estimation — Kernel density estimation is a nonparametric technique for density estimation i.e., estimation of probability density functions, which is one of the fundamental questions in statistics. It can be viewed as a generalisation of histogram density… … Wikipedia
Atmospheric Neutral Density Experiment — The Atmospheric Neutral Density Experiment (ANDE) is an experiment using two spherical satellites to measure the effects of atmospheric drag on spacecraft. ANDE is part of the Space Test Program of the United States Department of Defense, and was … Wikipedia
