61Discrete event simulation — In discrete event simulation, the operation of a system is represented as a chronological sequence of events. Each event occurs at an instant in time and marks a change of state in the system [1]. For example, if an elevator is simulated, an… …
62Discrete dipole approximation — In discrete dipole approximation larger object is approximated in terms of discrete dipoles The discrete dipole approximation (DDA) is a method for computing scattering of radiation by particles of arbitrary shape and by periodic structures.… …
63Discrete Mathematics (journal) — For the area of mathematics, see Discrete mathematics. Discrete Mathematics   Abbreviated title ( …
64Discrete wavelet transform — An example of the 2D discrete wavelet transform that is used in JPEG2000. The original image is high pass filtered, yielding the three large images, each describing local changes in brightness (details) in the original image. It is then low pass… …
65Discrete spectrum — For a mathematically rigorous point of view of discrete spectrum , see decomposition of spectrum (functional analysis). In physics, an elementary (and accurate) explanation of a discrete spectrum is that it is an emission spectrum or absorption… …
66Discrete sine transform — In mathematics, the discrete sine transform (DST) is a Fourier related transform similar to the discrete Fourier transform (DFT), but using a purely real matrix. It is equivalent to the imaginary parts of a DFT of roughly twice the length,… …
67Discrete phase-type distribution — The discrete phase type distribution is a probability distribution that results from a system of one or more inter related geometric distributions occurring in sequence, or phases. The sequence in which each of the phases occur may itself be a… …
68Discrete Hartley transform — A discrete Hartley transform (DHT) is a Fourier related transform of discrete, periodic data similar to the discrete Fourier transform (DFT), with analogous applications in signal processing and related fields. Its main distinction from the DFT… …
69Discrete Fourier transform (general) — See also: Fourier transform on finite groups This article is about the discrete Fourier transform (DFT) over any field (including finite fields), commonly called a number theoretic transform (NTT) in the case of finite fields. For specific… …
70Discrete cosine transform — Transformée en cosinus discrète La transformée en cosinus discrète ou TCD (de l anglais : DCT ou Discrete Cosine Transform) est une transformation proche de la transformée de Fourier discrète (DFT). Le noyau de projection est un cosinus et… …
