**Mean width**— In geometry, the mean width is a measure of dimension length of the size a body; see Hadwiger s theorem for more about the available measures of bodies. In n dimensions, one has to consider (n − 1) dimensional hyperplanes perpendicular to a given …72

**Surface of constant width**— In geometry, a surface of constant width is a convex form whose width, measured by the distance between two opposite parallelplanes touching its boundary, is the same regardless of the direction of those two parallel planes. One defines the width …73

**Zero-width non-joiner**— The zero width non joiner (ZWNJ) is a non printing character used in the computerization of writing systems that make use of ligatures. When placed between two characters that would otherwise be connected into a ligature, a ZWNJ causes them to be …74

**Clique-width**— In graph theory, the clique width of a graph G is the minimum number of labels needed to construct G by means of the following 4 operations : Creation of a new vertex v with label i ( noted i(v) ) Disjoint union of two labeled graphs G and H …75

**Never Mind the Quality Feel the Width**— Never Mind The Quality, Feel The Width Genre Sitcom Created by Harry Driver Vince Powell Starring John Bluthal Joe Lynch Cyril Shaps Eamon Kelly Country of origin …76

**Pulse-width modulation**— (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load. PrinciplePulse width modulation uses a square wave whose pulse… …77

**Realized Niche Width**— is a phrase relating to ecology defining the actual space that an organism inhabits.Niche Width vs Realized Niche WidthThe Niche Width of an organism refers to the area which that species could physically inhabit. This area is defined by suitable …78

**Face width**— The face width of a gear is the length of teeth in an axial plane. For double helical, it does not include the gap.Total face width is the actual dimension of a gear blank including the portion that exceeds the effective face width, or as in… …79

**beam width**— The full angular interval in the horizontal plane between the points at which the power radiated from the antenna has fallen to half its maximum value. In practice, the effective beam width may be less than this value and may be altered by use of …80

**Spectral width**— In telecommunications, spectral width is the wavelength interval over which the magnitude of all spectral components is equal to or greater than a specified fraction of the magnitude of the component having the maximum value. In optical… …
