Mellin transformation

The second method is more elegant, because it only involves the numerical computation of moments (cf. Sect. 1.3) of the smeared CLDg2 (rn) followed by moment arithmetics [200], The first step is the computation of the Mellin transform102 of the analytical function gc (rn) which we have selected to describe the needle diameter shape. This is readily accomplished by Mathematica [205], Because the Mellin transform is just a generalized moment expansion, we retrieve for the moments of the normalized chord distribution of the unit-disc103... 

Moments are obtained from a Mellin transform by changing from s to i + 1. 

Since we will, see further below, introduce the Mellin transformation to analyze scale invariance in connection with the micro-macro problems, it will be natural to rewrite some of our formulas in a spherical coordinate system, i.e., in terms of (r,, ) = (r, 2) with (u ru)... 

The proof follows by direct differentiation of both sides of Eq. (D.6) with respect to the parameter ft. Alternatively one can work with the Mellin transformation (here restricted to N = 1 for simplicity) between v and v... 

Taking Mellin transforms with respect to A and inverting, we can estimate the integral representation... 

In this paper the stresses in a joint with a functionally graded material (FGM) are analyzed. In the middle of a joint with FGM the stresses have been calculated analytically by using the plate theory. The effect of the thickness of the FGM layer and the effect of the transition function form on the stresses in the joint is discussed. Near the free edges of the interface in a joint with FGM, the stresses are described analytically by using the Mellin transform method. Some examples are presented to show the good agreement of the stresses calculated from FEM and with the analytical description in a joint with graded material.

We make now, similarly as is common with the different integral transforms, a correspondence table between the stochastic variable and the associated characteristic function. Note, there are several integral transforms. The most well-known integral transformation might be the Fourier transform. Further, we emphasize the Laplace transform, the Mellin transform, and the Hilbert transform. These transformations are useful for the solution of various differential equations, in communications technology, all ranges of the frequency analysis, also for optical problems and much other more. We designate the stochastic variable with X. The associated characteristic function should be...

In this entry some relevant examples on the use of fractional calculus to earthquake ground motion modeled as a stationary normal colored noise are presented. Applications of fractional calculus for the description of mono- and multivariate earthquake accelerations and exact filter equation are obtained in an integral form involving Riesz fractional operator in zero. The latter are related to complex spectral moments by Mellin transform operator. Other relevant application in probability may be found in Cottone et al. (2010) and Di Paola and Pinnola (2012). 

In order to derive the filter equations, we need of other two relevant definitions the Riesz fractional operator and the Mellin transform.
