LSIAC-MRA for Nonuniform Meshes and Applications to Mesh Adaptivity
Matthew J. Picklo, Jennifer K. Ryan
In this article we consider the extension of the (L)SIAC-MRA enhancement procedure to nonuniform meshes. We demonstrate that error reduction can be obtained on perturbed quadrilate…
High-Order Entropy Correction with SIAC Filters
Matthew J. Picklo, Ayaboe K. Edoh
This article considers the application of Smoothness-Increasing Accuracy-Conserving (SIAC) filtering for the non-linear stabilization of discontinuous Galerkin (DG) discretizations…
Denoising Particle-In-Cell Data via Smoothness-Increasing Accuracy-Conserving Filters with Application to Bohm Speed Computation
Matthew J. Picklo, Qi Tang, Yanzeng Zhang +2
The simulation of plasma physics is computationally expensive because the underlying physical system is of high dimensions, requiring three spatial dimensions and three velocity di…
Enhanced Multi-Resolution Analysis for Multi-Dimensional Data Utilizing Line Filtering Techniques
Matthew J. Picklo, Jennifer K. Ryan
In this article we introduce Line Smoothness-Increasing Accuracy-Conserving Multi-Resolution Analysis\linebreak (LSIAC-MRA). This is a procedure for exploiting convolution kernel p…
