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,
Cylinder set measure the space of tempered distributions, which extends to a measure on the space of tempered distributions, "S"′. The Hilbert space "H" has measure 0 in "S"′, by the first argument used above to show that the canonical Gaussian cylinder set measure on "H" does not extend to a measure on "H". Cylinder set measure In mathematics, cylinder set measure (or promeasure, or premeasure, or quasi-measure, or CSM) is a kind of prototype for a measure on an infinite-dimensional vector space. An example is the Gaussian cylinder set measure on Hilbert space. Cylinder set measures are in general not measures (and
