A direct procedure for interpolation on a structured curvilinear two-dimensional grid [PDF]

A direct procedure is presented for locally bicubic interpolation on a structured, curvilinear, two-dimensional grid. The physical (Cartesian) space is transformed to a computational space in which the grid is uniform and rectangular by a generalized ...

Spatial interpolation of dry deposition using EOF models

Revista de Matemática: Teoría y Aplicaciones, 2009
Random processes are monitored over space and time by a network of stations distributed across a spatial region. Auxiliary information is often gathered not only at the stations but at other points across the region.

Interpolating Electron Diffusion Coefficients in Earth's Radiation Belts: A Neural Network Model Inspired by Video Frame Interpolation

Space Weather
Many numerical models have been built to uncover the physical mechanisms governing radiation belt dynamics and enable real‐time forecasting. The diffusion coefficient, as a critical input for these models, is usually obtained through linear interpolation

Research on a coal seam modeling construction method based on improved kriging interpolation

Scientific Reports
To address the issues of large anomalous triangulations, invalid interpolations, and uneven boundary interpolations in kriging interpolation, we propose research on a coal seam modeling construction method based on improved kriging interpolation.

Effective H^{\infty} interpolation constrained by Hardy and Bergman weighted norms

, 2010
Given a finite set $\sigma$ of the unit disc $\mathbb{D}$ and a holomorphic function $f$ in $\mathbb{D}$ which belongs to a class $X$ we are looking for a function $g$ in another class $Y$ which minimizes the norm $|g|_{Y}$ among all functions $g$ such ...

Analysis of the influence of interpolation algorithm on the numerical simulation results of transmission boundary

地震科学进展
The distance traveled by contour wave with artificial wave velocity in a step-time is often inconsistent with the mesh size. Therefore, when the transmission boundary formula is applied, the calculation nodes of transmission boundary are usually ...

A variant of the method of characteristics

Computer Assisted Methods in Engineering and Science, 2023
A variant of the method of characteristics for hyperbolic conservation laws is proposed in this paper. It is based on the time interpolation instead of space interpolation as in the standard method of characteristics.

The Average Errors for the Grünwald Interpolation in the Wiener Space

Discrete Dynamics in Nature and Society, 2009
We determine the weakly asymptotically orders for the average errors of the Grünwald interpolation sequences based on the Tchebycheff nodes in the Wiener space.

Interpolation and random interpolation in de Branges–Rovnyak spaces

Journal of the London Mathematical Society
Abstract The aim of this paper is to characterize universal and multiplier interpolating sequences for de Branges–Rovnyak spaces where the defining function is a general non‐extreme rational function. Our results carry over to recently introduced higher order local Dirichlet spaces and thus generalize previously known results in ...
