Radial Basis Function Method for Predicting the Evolution of Aerosol Size Distributions for Coagulation Problems

open access: yesAtmosphere, 2022
The dynamic evolution of particle size distributions (PSDs) during coagulation is of great importance in many atmospheric and engineering applications. To date, various numerical methods have been developed for solving the general dynamic equation under ...

A construction of nonnegative approximate quadratures [PDF]

open access: yesMathematics of Computation, 1967
Tchakaloff's demonstration is a very beautiful one, involving the theory of convex bodies. A separating hyperplane is employed and a nonconstructive proof is obtained. The theorem is valid for weighted integrals of dimension d _ 1. Equivalent results on finite moment spaces were obtained earlier by various authors.

Monotonicity of Quadrature Approximations [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
For the general quadrature rules of Newton-Cotes we show that the convergence is monotone for the appropriate class of functions. Included are the well-known trapezoidal and Simpson rules.
