A Global Non-Hydrostatic Atmospheric Model with a Mass and Energy Conserving Vertically-Implicit-Correction (VIC) Scheme
Huazhi Ge, Cheng Li, Xi Zhang +1
Global non-hydrostatic atmospheric models are becoming increasingly important for studying the climates of planets and exoplanets. However, such models suffer from computational di…
A single-step third-order temporal discretization with Jacobian-free and Hessian-free formulations for finite difference methods
Youngjun Lee, Dongwook Lee
Discrete updates of numerical partial differential equations (PDEs) rely on two branches of temporal integration. The first branch is the widely-adopted, traditionally popular appr…
A Gaussian Process Upsampling Model for Improvements in Optical Character Recognition
Steven I Reeves, Dongwook Lee, Anurag Singh +1
Optical Character Recognition and extraction is a key tool in the automatic evaluation of documents in a financial context. However, the image data provided to automated systems ca…
An Application of Gaussian Process Modeling for High-order Accurate Adaptive Mesh Refinement Prolongation
Steven I. Reeves, Dongwook Lee, Adam Reyes +2
We present a new polynomial-free prolongation scheme for Adaptive Mesh Refinement (AMR) simulations of compressible and incompressible computational fluid dynamics. The new method…
