Legendre polynomial order selection in projection pursuit density estimation

Lietuvos Matematikos Rinkinys, 2013
Projection pursuit method and its application to probability density estimation is discussed. Method proposed by J.H. Friedman, based on projection density estimation using orthogonal Legendre polynomials, is analysed.

An Investigation into the Validity of the Temperature Profile Approximations across the Film Thickness in THD Analysis of Infinitely Wide Slider Bearing

Tribology Online, 2006
Many investigators have frequently assumed polynomial temperature profiles across the film thickness in the mathematical modeling of lubricating films in the hydrodynamic bearings in order to make computations simpler.

Properties of circumferential non-propagating waves in functionally graded piezoelectric cylindrical shells

Advances in Mechanical Engineering, 2019
Each guided elastic wave mode is composed of propagating and non-propagating branches. Non-propagating branches associated with complex wavenumbers are substantially different from the propagating ones.

The continous Legendre transform, its inverse transform, and applications

International Journal of Mathematics and Mathematical Sciences, 1980
This paper is concerned with the continuous Legendre transform, derived from the classical discrete Legendre transform by replacing the Legendre polynomial Pk(x) by the function Pλ(x) with λ real. Another approach to T.M. MacRobert's inversion formula is
