Quality, cost, delivery (QCD), sometimes expanded to quality, cost, delivery, morale, safety (QCDMS), [1] is a management approach originally developed by the British automotive industry. [2]
The meaning of this statement was usually clear in context: He meant quarks are confined, but he also was implying that the strong interactions could probably not be fully described by quantum field theory. Richard Feynman argued that high energy experiments showed quarks are real particles: he called them partons (since they were parts of ...
Mean-field methods are commonly used to analyse the phases. Another approach is the bag model , in which the effects of confinement are simulated by an additive energy density that penalizes unconfined quark matter.
One in four trade-ins associated with a new car or truck purchase in the fourth quarter last year was 'upside down,' according to Edmunds.
Landline and submarine telegraphers' telegraphs had adopted the convention of using the station code "CQ" to all stations along a telegraph line.As the first wireless operators were taken from the already trained landline telegraphers, the current practices carried forward and CQ had then been adopted in maritime radiotelegraphy as a "general call" to any ship or land station.
In lattice perturbation theory the scattering matrix is expanded in powers of the lattice spacing, a.The results are used primarily to renormalize Lattice QCD Monte-Carlo calculations.

Perturbative quantum chromodynamics (also perturbative QCD) is a subfield of particle physics in which the theory of strong interactions, Quantum Chromodynamics (QCD), is studied by using the fact that the strong coupling constant is small in high energy or short distance interactions, thus allowing perturbation theory techniques to be applied.
