Rayleigh unit
A Rayl, rayl or Rayleigh is one of two units of specific acoustic impedance or, equivalently, characteristic acoustic impedance; one an MKS unit, and the other a CGS unit. These have the same dimensions as momentum per volume. The units are named after John William Strutt, 3rd Baron Rayleigh. They are not to be confused with the rayleigh unit of photon flux, which is used to measure airglow and is named after his son, R… Web(41) can be plugged into (47) yielding the lower union bound for the Rayleigh case as Pr(ε) ≥ 1 2 + 1 2 1 2+σ2 H(E/N 0) −1 exp − ln(M −1) 1+σ2 H(E/N 0) .

WebFor Gaussian beams, the Rayleigh length is determined by the waist radius w 0 and the wavelength λ: " where the wavelength λ is the vacuum wavelength divided by the refractive index n of the material. For beams with imperfect beam quality and a given waist radius, the Rayleigh length is effectively decreased by the so-called M2 factor. WebJun 17, 2015 · In other words, the model (P) is to maximize the sum of a generalized Rayleigh quotient and another Rayleigh quotient on the unit sphere, which belongs to the class of the sum-of-ratios fractional programming. The model (P), initially proposed by Zhang [29, 30], is a mathematical reformulation of the following sum-of-quadratic-ratios …
