Rayleigh fading is a statistical model for the effect of a propagation environment on a radio signal, such as that used by wireless devices.. Rayleigh fading models assume that the magnitude of a signal that has passed through such a transmission medium (also called a communication channel) will vary randomly, or fade, according to a Rayleigh distribution — the radial component of the sum of ...
The Hanle effect, [1] also known as zero-field level crossing, [2] is a reduction in the polarization of light when the atoms emitting the light are subject to a magnetic field in a particular direction, and when they have themselves been excited by polarized light.
In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom .
The remainder are controlled by "Stop and Give Way" signs. Level crossings are the responsibility of rail infrastructure owner KiwiRail Network, the NZ Transport Agency, and if the crossing is on a local road, the local city or district council. Much like Australia, New Zealand employs American-made crossing warning equipment. [51]

Gated level crossings were mandatory from 1839, but initial rules were for the gates to be ordinarily kept closed across the highway. [6] The original form of road level crossing on British railways dates from 1842 onwards, [6] [7] it consisted of two or four wooden gates (one or two on each side of the railway). When open to road traffic, the ...
The level crossing immediately to the east of the station was converted to automatic-opening on 9 March 1986 and to automatic half-barriers on 4 April 1993. [ 1 ] Electrification of the Wickford to Southminster line, using 25 kV overhead line electrification, was completed on 12 May 1986.
The equation is named after Lord Rayleigh, who introduced it in 1880. [2] The Orr–Sommerfeld equation – introduced later, for the study of stability of parallel viscous flow – reduces to Rayleigh's equation when the viscosity is zero. [3] Rayleigh's equation, together with appropriate boundary conditions, most often poses an eigenvalue ...
