Device for Connection of Luminaires (DCL) is a European standard for ceiling light fixtures introduced in 2005 and refined in 2009. It uses 6 ampere. It uses 6 ampere. DCL must carry the CE marking as per the Low Voltage Directive .
DIGITAL Command Language (DCL) is the standard command language adopted by many of the operating systems created by Digital Equipment Corporation.DCL had its roots in IAS, TOPS-20, and RT-11 and was implemented as a standard across most of Digital's operating systems, notably RSX-11 and RSTS/E, but took its most powerful form in VAX/VMS (later OpenVMS).
Operating leverage can also be measured in terms of change in operating income for a given change in sales (revenue).. The Degree of Operating Leverage (DOL) can be computed in a number of equivalent ways; one way it is defined as the ratio of the percentage change in Operating Income for a given percentage change in Sales (Brigham 1995, p. 426):
The DCL and ICL plants effectively complemented each other rather than competed. The reason for this is that coal hydrogenation yields high quality gasoline for aviation and motors, while FT synthesis chiefly produced high-quality diesel, lubrication oil, and waxes together with some smaller amounts of lower-quality motor gasoline.
These sub-languages are mainly categorized into four categories: a data query language (DQL), a data definition language (DDL), a data control language (DCL), and a data manipulation language (DML). Sometimes a transaction control language (TCL) [1] is argued to be part of the sub-language set as well.
DFL primarily refers to the Minnesota Democratic–Farmer–Labor Party, an affiliate of the U.S. Democratic Party. It may also refer to: Cosworth DFL, a variant of the Cosworth DFV Formula One engine, intended for Group C racing; David Florida Laboratory, a Canadian aerospace laboratory; Degree of financial leverage, a metric of leverage (finance)
Deflection (f) in engineering. In structural engineering, deflection is the degree to which a part of a long structural element (such as beam) is deformed laterally (in the direction transverse to its longitudinal axis) under a load.
A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x 3 − 3x + d = 0, where is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
