Parameterization of 3D cloud geometry and a neural-network-based fast forward operator for polarized radiative transfer [PDF]

Atmospheric Measurement Techniques
Clouds 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.

Electronic, structural and optical properties of zincblend and wurtizite cadmium selenide (CdSe) using density functional theory and hubbard correction

Фізика і хімія твердого тіла, 2021
Zinc blend (zb) and wurtizite (wz) structure of cadmium selenide (CdSe) is determined using density-functional theory within local density approximation (LDA), generalized gradient approximation (GGA), Hubbard-correction (GGA+U) and Hybrid functional ...

On the spectrum of the finite element approximation of a three field formulation for linear elasticity

Examples and Counterexamples, 2022
We continue the investigation on the spectrum of operators arising from the discretization of partial differential equations. In this paper we consider a three field formulation recently introduced for the finite element least-squares approximation of ...

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.

Complex approximation by real approximation [PDF]

مجلة جامعة الانبار للعلوم الصرفة
It is known that approximation of the complex functions does not, in general, depend on approximation of the real functions. However, if the complex function is viewed as a Cartesian product of two real functions, a relationship appears between the two ...

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 ...

Approximation by Zygmund means in variable exponent Lebesque spaces [PDF]

Mathematica Moravica, 2019
In the present work we investigate the approximation of the functions by the Zygmund means in variable exponent Lebesgue spaces. Here the estimate which is obtained depends on sequence of the best approximation in Lebesgue spaces with variable exponent ...
