CATAPULT: A CUDA-Accelerated Timestepper for Alpha Particles Using Local Tricubics
Michael Czekanski, Alexey R. Knyazev, David Bindel +1
We introduce a CUDA-Accelerated Timestepper for Alpha Particles Using Local Tricubics (CATAPULT) for use in Monte Carlo calculations of alpha particle confinement in stellarators.…
Stochastic Poisson Surface Reconstruction with One Solve using Geometric Gaussian Processes
Sidhanth Holalkere, David S. Bindel, Silvia Sellán +1
Poisson Surface Reconstruction is a widely-used algorithm for reconstructing a surface from an oriented point cloud. To facilitate applications where only partial surface informati…
The High-Order Magnetic Near-Axis Expansion: Ill-Posedness and Regularization
Maximilian Ruth, Rogerio Jorge, David Bindel
When analyzing stellarator configurations, it is common to perform an asymptotic expansion about the magnetic axis. This so-called near-axis expansion is convenient for the same re…
Differentiating Policies for Non-Myopic Bayesian Optimization
Darian Nwankwo, David Bindel
Bayesian optimization (BO) methods choose sample points by optimizing an acquisition function derived from a statistical model of the objective. These acquisition functions are cho…
