Linear System Analysis and Optimal Control of Natural Gas Dynamics in Pipeline Networks
Luke S. Baker, Sachin Shivakumar, Dieter Armbruster +2
We design nonlinear and adaptive linear model-predictive control (MPC) techniques to minimize operational costs of compressor-actuated dynamics in natural gas pipeline networks. We…
Optimal Control of Transient Flows in Pipeline Networks with Heterogeneous Mixtures of Hydrogen and Natural Gas
Luke Baker, Saif R. Kazi, Rodrigo B. Platte +1
We formulate a control system model for the distributed flow of mixtures of highly heterogeneous gases through large-scale pipeline networks with time-varying injections of constit…
Fourier Analysis, Computing, and Image Formation for Spotlight Synthetic Aperture Radar
Toby Sanders, Christian Dwyer, Rodrigo B. Platte
This article is written to serve as an introduction and survey of imaging with synthetic aperture radar (SAR). The reader will benefit from having some familiarity with harmonic an…
Multiscale Higher Order TV Operators for L1 Regularization
Toby Sanders, Rodrigo B. Platte
In the realm of signal and image denoising and reconstruction, regularization techniques have generated a great deal of attention with a multitude of variants. A key compo…
Optimal sampling rates for approximating analytic functions from pointwise samples
Ben Adcock, Rodrigo Platte, Alexei Shadrin
We consider the problem of approximating an analytic function on a compact interval from its values at distinct points. When the points are equispaced, a recent result (the s…
Recovering Fine Details from Under-Resolved Electron Tomography Data using HOTV Regularization
Toby Sanders, Anne Gelb, Rodrigo Platte +2
Over the last decade or so, reconstruction methods using regularization, often categorized as compressed sensing (CS) algorithms, have significantly improved the capabilit…
Blow-up criteria for the 3d cubic nonlinear Schrödinger equation
Justin Holmer, Rodrigo Platte, Svetlana Roudenko
We consider solutions to the 3d nonlinear Schrödinger equation . In particular, we are interested in finding criteria on the initial data t…
