Discrete aurorae often display magnetic field lines or curtain-like structures, and can change within seconds or glow unchanging for hours, most often in fluorescent green.

* Discrete Fourier transform ( DFT ), occasionally called the finite Fourier transform, the Fourier transform of a discrete periodic sequence ( yielding discrete periodic frequencies ), which can also be thought of as the DTFT of a finite-length sequence evaluated at discrete frequencies

* Discrete probability distribution, a random variable that can be counted

Discrete groups can therefore be identified with their underlying ( non-topological ) groups.

Discrete signals may have several origins, but can usually be classified into one of two groups:

Discrete control functions can be represented by discrete levels of current sent over a loop.

Approximations of the Laplacian, obtained by the finite difference method or by the finite element method can also be called Discrete Laplacians.

Discrete signals, used in digital signal processing, can be obtained by sampling and quantization of continuous signals.

Discrete variables can have Dirichlet parents, and Poisson and exponential nodes must have gamma parents.

Various fuzzy membership generation algorithms can be used: Learning Vector Quantization ( LVQ ), Fuzzy Kohonen Partitioning ( FKP ) or Discrete Incremental Clustering ( DIC ).

It should not be confused with Discrete geometry ( Combinatorial geometry ).

Discrete variable protocols were the first to be invented, and they remain the most widely implemented.

The ORDVAC or Ordnance Discrete Variable Automatic Computer, an early computer built by the University of Illinois for the Ballistics Research Laboratory at Aberdeen Proving Ground, was based on the IAS architecture developed by John von Neumann, which came to be known as the von Neumann architecture.

Compatible Discrete 4 ( CD-4 ) or Quadradisc ( not to be confused with compact disc ) was introduced in May 1972 as a discrete quadraphonic system created by JVC and RCA.

Oppen had begun working on poems for what was to be his first book, Discrete Series, a seminal work in early Objectivist history.

Discrete circuits of hundreds or thousands of transistors quickly expand to occupy hundreds or thousands of square centimeters of circuit board area, and for very high-speed circuits such as those used in modern digital computers, the distance between transistors ( and the minimum capacitance of the connections between them ) also makes the desired speeds grossly unattainable, so that if these designs cannot be built as integrated circuits, then they simply cannot be built.

( Discrete here means " constituting a separate entity " and is distinct from " discreet "; a " discreet signal " is one not intended to be seen by others.

Discrete systems may be contrasted with continuous systems, which may also be called analog systems.

Discrete transition may be associated with events.

Discrete geometry or combinatorial geometry may be loosely defined as study of geometrical objects and properties that are discrete or combinatorial, either by their nature or by their representation ; the study that does not essentially rely on the notion of continuity.

Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous.

Discrete mathematics therefore excludes topics in " continuous mathematics " such as calculus and analysis.

Discrete symmetry groups come in three types: ( 1 ) finite point groups, which include only rotations, reflections, inversion and rotoinversion-they are in fact just the finite subgroups of O ( n ), ( 2 ) infinite lattice groups, which include only translations, and ( 3 ) infinite space groups which combines elements of both previous types, and may also include extra transformations like screw axis and glide reflection.

Discrete time signal processing is for sampled signals that are considered as defined only at discrete points in time, and as such are quantized in time, but not in magnitude.
