WebRayleigh’s inﬂection point theorem and Fjortoft’s theorem provide necessary conditions for inviscid temporal instability of a plane parallel ﬂow. Although these theorems have been assumed to hold in the spatial framework also, a rigorous theoretical basis for such an application is not available in the literature. WebThis paper discusses the sequential estimation of the scale parameter of the Rayleigh distribution using the three-stage sequential sampling procedure proposed by Hall (Ann. Stat.1981, 9, 1229–1238). Both point and confidence interval estimation are considered via a unified optimal decision framework, which enables one to make the maximum use of the …

WebHoward’s semi-circle theorem This is a result placing bounds on the phase velocity and the maximum growth rate of any unstable wave. Howard’s semi-circle theorem is derived in a similar manner to Rayleigh’s and Fj˝rtoft’s, but from theadjointof the Rayleigh equation. The adjoint equation has the same eigenvalues as the Rayleigh equation.
