A Proof of Principle: Multi-Modality Radiotherapy Optimization
Roman Levin, Aleksandr Y. Aravkin, Minsun Kim
Radiotherapy is used to treat cancer patients by damaging DNA of tumor cells using ionizing radiation. Photons are the most widely used radiation type for therapy, having been put…
Efficient Robust Parameter Identification in Generalized Kalman Smoothing Models
Jonathan Jonker, Peng Zheng, Aleksandr Y. Aravkin
Dynamic inference problems in autoregressive (AR/ARMA/ARIMA), exponential smoothing, and navigation are often formulated and solved using state-space models (SSM), which allow a ra…
Preliminary Results in Current Profile Estimation and Doppler-aided Navigation for Autonomous Underwater Gliders
Jonathan Jonker, Andrey Shcherbina, Richard Krishfield +3
This paper describes the development and experimental results of navigation algorithms for an autonomous underwater glider (AUG) that uses an on-board acoustic Doppler current prof…
A nonconvex optimization approach to IMRT planning with dose-volume constraints
Kelsey Maass, Minsun Kim, Aleksandr Aravkin
Fluence map optimization for intensity-modulated radiation therapy planning can be formulated as a large-scale inverse problem with competing objectives and constraints associated…
Robust Singular Smoothers For Tracking Using Low-Fidelity Data
Jonathan Jonker, Aleksandr Aravkin, James V. Burke +2
Tracking underwater autonomous platforms is often difficult because of noisy, biased, and discretized input data. Classic filters and smoothers based on standard assumptions of Gau…
Offline state estimation for hybrid systems via nonsmooth variable projection
Jize Zhang, Andrew M. Pace, Samuel A. Burden +1
A hybrid dynamical system switches between dynamic regimes at time- or state-triggered events. We propose an offline algorithm that simultaneously estimates discrete and continuous…
