Quadrature by Matched Asymptotic Expansion (QBMAX): Accelerating Evaluation of Layer Potentials with Boundary Layers
Chaoqi Lin, Xiaoyu Wei, Andreas Klöckner
Evaluating layer potentials with rapidly decaying kernels becomes computationally challenging in the presence of boundary layers, as occurs for Helmholtz layer potentials with larg…
Exact domain truncation for the Morse-Ingard equations
Robert C. Kirby, Xiaoyu Wei, Andreas Kloeckner
Morse and Ingard give a coupled system of time-harmonic equations for the temperature and pressure of an excited gas. These equations form a critical aspect of modeling trace gas s…
Integral Equation Methods for the Morse-Ingard Equations
Xiaoyu Wei, Andreas Klöckner, Robert C. Kirby
We present two (a decoupled and a coupled) integral-equation-based methods for the Morse-Ingard equations subject to Neumann boundary conditions on the exterior domain. Both method…
An Integral Equation Method for the Cahn-Hilliard Equation in the Wetting Problem
Xiaoyu Wei, Shidong Jiang, Andreas Kloeckner +1
We present an integral equation approach to solving the Cahn-Hilliard equation equipped with boundary conditions that model solid surfaces with prescribed Young's angles. The discr…
An efficient iterative thresholding method for image segmentation
Dong Wang, Haohan Li, Xiaoyu Wei +1
We proposed an efficient iterative thresholding method for multi-phase image segmentation. The algorithm is based on minimizing piecewise constant Mumford-Shah functional in which…
