WebNow, here is a general statement of the Rayleigh-Ritz from Garling's Inequalities (p. 246) Suppose that T = ∑ n = 1 ∞ s n ( T) ⋅, x n y n ∈ K ( H 1, H 2) (that is compact from H 1 to H 2) where ( x n) and ( y n) are orthonomral sequences in H 1 and H 2, respectively, and ( s n ( T)) is a decreasing sequence of non-negative real numbers ... WebRayleigh's inflexion-point theorem: A necessary condition for instability is that the basic velocity profile should have an inflexion point. Proof: Write Rayleigh's equation in the form. (12) and suppose that so that the equation is non-singular. Multiplying by , integrating from to (using BCs and integration by parts) we have.

Webcentral limit theorem, lh~(r’, t)l follows Rayleigh fading for every 7’. After h~(r; t) is generated, gm(t) can be computed by (9) with h(r; L) approximated by h~(r; t), and 3k can be calculated by (8). In general, the amount of computation is proportional to the number of Rayleigh-faded paths considered sufficient
