Candela per square metre Candela per square metre The candela per square metre (cd/m) is the derived SI unit of luminance. The unit is based on the candela, the SI unit of luminous intensity, and the square metre, the SI unit of area. Nit (nt) is a non-SI name also used for this unit (1 nt = 1 cd/m). The term "nit" is believed to come from the Latin word "nitere", to shine. As a measure of light emitted per unit area, this unit is frequently used to specify the brightness of a display device. The sRGB spec for monitors targets 80 cd/m. Typically,
Convex measure Convex measure In measure and probability theory in mathematics, a convex measure is a probability measure that — loosely put — does not assign more mass to any intermediate set “between” two measurable sets "A" and "B" than it does to "A" or "B" individually. There are multiple ways in which the comparison between the probabilities of "A" and "B" and the intermediate set can be made, leading to multiple definitions of convexity, such as log-concavity, harmonic convexity, and so on. The mathematician Christer Borell was a pioneer of the detailed study of convex measures on locally convex spaces in
