The acoustic power of an oscillating flame is measured. A turbulent premixed propane/air flame is situated near a pressure antinode of a standing wave in a laboratory combustion chamber. This standing wave is generated by a piston. The fluctuating heat release of the flame will supply acoustic power to the standing wave as postulated by Rayleigh. This flame acoustic power is obtained by setting...

Let fX1; : : : ; Xng be a collection of binary valued random variables and let f : f0; 1g n ! R be a Lipschitz function. Under a negative dependence hypothesis known as the strong Rayleigh condition, we show that f Ef satis es a concentration inequality. The class of strong Rayleigh measures includes determinantal measures, weighted uniform matroids and exclusion measures; some familiar example...

We present a novel mathematical approach that for the first time allows for calculating the moment generating function of mutual information of Rayleigh fading MIMO channels with arbitrary fading correlation at transmitter and receiver. Specifically, we make use of certain hypergeometric functions of matrix argument, which are frequently used in multivariate statistics. This allows for a concis...

In the present study an effort has been made to find out the best fitting distribution of wind speed data recorded in Islamabad on a daily basis for the years 2001 to 2003. For this purpose two parameter Gamma, Weibull, Lognormal, Rayleigh, three parameter Burr and Frechet distributions are fitted to data and parameters for each distribution are estimated using the Maximum Likelihood (ML) metho...

The action spectrum for inducing a long-lasting protan shift in colour matches was investigated. Rayleigh matches were measured before and after 30 min adaptation to monochromatic light of 520, 550, 580 or 620 nm. For each wavelength, seven retinal illuminances, ranging from 3.0 to 5.0 log td, were chosen in random order. Results for one colour-normal observer show that the shift in Rayleigh ma...
