a measure of the zone or band broadening in chromatography expressed as plate height or number of plates.

a measure of how much paper is used to obtain features of the subject versus extra paper that is merely hidden away.

A measure of EDM performance which varies with the on and off time settings for an EDM cut. Duty cycle.

A measure of how well resources are utilized. Efficiency is typically expressed in time but may expressed as another available component such as money.

a measure of the ability of the distillation column to separate compounds. This is usually referred to in theoretical plates.

A measure of the timeliness and affordability of an action.

A measure determined by the number of theoretical plates calculated from the equation: This can be visually represented by the following figure. Measure peak width at 4.4% of peak height

A measure of the bureaucratic competence of a world. Efficiency affects such areas as production, defense, technology increases, etc.

A measure of the amount of time a parallel programs spends doing computation as opposed to communication. Efficiency is defined as speedup / number of processors. The closer it is to 1, the more perfectly parallel the task is at that level of parallelism; the closer to 0, the less parallel.

In statistics, efficiency is one measure of desirability of an estimator.
