Excitation and Identifiability in the 2D Navier-Stokes equations
Vincent R. Martinez, Sarah Strikwerda, Xiang Wan
Convergence in parameter estimation classically requires ``persistency of excitation," which is a non-degeneracy condition on a trajectory-dependent signal. This paper develops, to…
Sharp Interface Dynamics in a Minimal Non-Reciprocal Cahn-Hilliard System
Daniel Gomez, Yoichiro Mori, Sarah Strikwerda
Interest in non-reciprocally coupled systems recently led to the introduction of a minimal non-reciprocally coupled Cahn-Hilliard (CH) model by Brauns and Marchetti in 2024 arXiv:2…
A hierarchy of blood vessel models, Part II: 3D-3D to 3D-1D and 1D
Laurel Ohm, Sarah Strikwerda
We propose and analyze a hierarchy of three models of blood perfusion through a tissue surrounding a thin arteriole or venule. Our goal is to rigorously link 3D-3D Darcy--Stokes, 3…
A hierarchy of blood vessel models, Part I: 3D-1D to 1D
Laurel Ohm, Sarah Strikwerda
We propose and analyze a family of models describing blood perfusion through a tissue surrounding a thin blood vessel. Our goal is to rigorously establish convergence results among…
Controlling Klein-Gordon Chains and Lattices
Sarah Strikwerda, Hung Vinh Tran, Minh-Binh Tran
In this work, we initiate the study of controlling nonlinear Klein-Gordon chains and lattices through their emergent collective flocking behavior. By constructing appropriate feedb…
Input Regularization for Integer Optimal Control in BV with Applications to Control of Poroelastic and Poroviscoelastic Systems
Lorena Bociu, Paul Manns, Marvin Severitt +1
We revisit a class of integer optimal control problems for which a trust-region method has been proposed and analyzed in arXiv:2106.13453v3 [math.OC]. While the algorithm proposed…
Solving Bang-Bang Problems Using The Immersed Interface Method and Integer Programming
Ryan H. Vogt, Sarah Strikwerda
In this paper we study numerically solving optimal control problems with bang-bang control functions. We present a formal Lagrangian approach for solving the optimal control proble…
