ParticLS: Object-oriented software for discrete element methods and peridynamics
Andrew D. Davis, Brendan A. West, Nathanael J. Frisch +2
ParticLS (\emph{Partic}le \emph{L}evel \emph{S}ets) is a software library that implements the discrete element method (DEM) and meshfree methods. ParticLS tracks the interaction be…
Bonded discrete element simulations of sea ice with non-local failure: Applications to Nares Strait
Brendan West, Devin O'Connor, Matthew Parno +2
The discrete element method (DEM) can provide detailed descriptions of sea ice dynamics that explicitly model floes and discontinuities in the ice, which can be challenging to repr…
A phase field model for cohesive fracture in micropolar continua
Hyoung Suk Suh, WaiChing Sun, Devin O'Connor
While crack nucleation and propagation in the brittle or quasi-brittle regime can be predicted via variational or material-force-based phase field fracture models, these models oft…
Remote measurement of sea ice dynamics with regularized optimal transport
M. D. Parno, B. A. West, A. J. Song +2
As Arctic conditions rapidly change, human activity in the Arctic will continue to increase and so will the need for high-resolution observations of sea ice. While satellite imager…
Improved Workflow for Unsupervised Multiphase Image Segmentation
Brendan A. West, Taylor S. Hodgdon, Matthew D. Parno +1
Quantitative image analysis often depends on accurate classification of pixels through a segmentation process. However, imaging artifacts such as the partial volume effect and sens…
An introduction to sampling via measure transport
Youssef Marzouk, Tarek Moselhy, Matthew Parno +1
We present the fundamentals of a measure transport approach to sampling. The idea is to construct a deterministic coupling---i.e., a transport map---between a complex "target" prob…
