Approximation of the critical buckling factor for composite panels [PDF]
, 2012 This article is concerned with the approximation of the critical buckling factor for thin composite plates. A new method to improve the approximation of this critical factor is applied based on its behavior with respect to lamination parameters and ...

Parameterization of 3D cloud geometry and a neural-network-based fast forward operator for polarized radiative transfer [PDF]
Atmospheric Measurement TechniquesClouds generally have a complex three-dimensional geometry. However, realistic three-dimensional radiative transfer simulations of clouds are computationally expensive, so most retrievals of cloud properties assume one-dimensional clouds, which ...

Linear Chebyshev Approximation in the Complex Plane Using Lawson's Algorithm [PDF]
Mathematics of Computation, 1976 In this paper we discuss the application of Lawson’s algorithm for computing best linear Chebyshev approximations to complex-valued functions. Some numerical examples are also presented.

Universal approximation theorem for Dirichlet series
International Journal of Mathematics and Mathematical Sciences, 2006 The paper deals with an extension theorem by Costakis and Vlachou on simultaneous approximation for holomorphic function to the setting of Dirichlet series, which are absolutely convergent in the right half of the complex plane.
