Construction of lattice rules for multiple integration based on a weighted discrepancy
, 2008 High-dimensional integrals arise in a variety of areas, including quantum physics, the physics and chemistry of molecules, statistical mechanics and more recently, in financial applications. In order to approximate multidimensional integrals, one may use

Associated symmetric quadrature rules
, 1996 We prove a relation between two different types of symmetric quadrature rules, where one of the types is the classical symmetric interpolatory quadrature rules.

The relationship between equatorial wave interaction and heavy rainfall in Southeast Asia
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study examines the statistical relationship between co‐occurring equatorial waves and heavy rainfall in Southeast Asia. Heavy rainfall is more closely related to combined wave activity than to individual waves in many regions of Southeast Asia. The figure shows GPM–IMERG rainfall (shading) and ERA5 850‐hPa winds (vectors) composited on days when ...

Trapezoidal Type Rules from an Inequalities Point of View
, 1999 The article investigates trapezoid type rules and obtains explicit bounds through the use of a Peano kernel approach and the modern theory of inequalities. Both Riemann-Stieltjes and Riemann integrals are evaluated with a variety of assumptions about the

Analysis of the fractional scattering contribution in the forward peak for multicomponent systems
Quarterly Journal of the Royal Meteorological Society, EarlyView.Derivation and justification of mixing rules for multicomponent systems. A novel formulation of the delta‐Eddington scaling rule. Analytical guidance for comparing radiative transfer results. Abstract The widely used δ‐Eddington approximation improves the accuracy of radiative transfer calculations by representing the fraction of scattering into the ...

An iterative method based on the average quadrature formula [PDF]
Computational Algorithms and Numerical DimensionsIn our research, a new third-order iterative method has been introduced. This method involves the creation of a new quadrature formula by averaging Simpson's 1/3 rd and Trapezoidal rules.

On Convergence of Quadrature Methods for the Lipschitz-Continuous Functions
, 2000 In this article we present a new approach to quadrature methods where any quadrature formula is generated by a discontinuous function whose jumps are quadrature weights.
