The DDA method can be implemented using floating-point or integer arithmetic. The native floating-point implementation requires one addition and one rounding operation per interpolated value (e.g. coordinate x, y, depth, color component etc.) and output result.
Amsterdam Density Functional (ADF) is a program for first-principles electronic structure calculations that makes use of density functional theory (DFT). [1] ADF was first developed in the early seventies by the group of E. J. Baerends from the Vrije Universiteit in Amsterdam, and by the group of T. Ziegler from the University of Calgary.
DA – density altitude; a reference to qualities in the air. Dial-in (bracket racing) – a car's pre-estimated ET for a pass, used for handicapping the start; Diaper – an absorbent containment blanket under the engine to prevent/reduce oil contact with the track, in the event of parts breakage

As noted earlier, , =,. The total drag coefficient can be estimated as: = [()], where is the propulsive efficiency, P is engine power in horsepower, sea-level air density in slugs/cubic foot, is the atmospheric density ratio for an altitude other than sea level, S is the aircraft's wing area in square feet, and V is the aircraft's speed in miles per hour.
The calculator can evaluate and simplify algebraic expressions symbolically. For example, entering x^2-4x+4 returns x 2 − 4 x + 4 {\displaystyle x^{2}-4x+4} . The answer is " prettyprinted " by default; that is, displayed as it would be written by hand (e.g. the aforementioned x 2 − 4 x + 4 {\displaystyle x^{2}-4x+4} rather than x^2-4x+4 ).

DMol 3 is a commercial (and academic) software package which uses density functional theory with a numerical radial function [1] basis set to calculate the electronic properties of molecules, clusters, surfaces and crystalline solid materials [2] from first principles.
