Extended Phase Unwrapping Max-Flow/Min-Cut Algorithm for Multibaseline SAR Interferograms Using a Two-Stage Programming Approach [PDF]
Sensors, 2020 Multi-baseline (MB) phase unwrapping (PU) is a key step of MB synthetic aperture radar (SAR) interferometry (InSAR). Compared with the traditional single-baseline (SB) PU, MB PU is applicable to the area where topography varies violently without obeying ...

Appointment Scheduling at Outpatient Clinics Using Two-Stage Stochastic Programming Approach [PDF]
IEEE Access, 2020 Clinics with a large volume of patients are often burdened with limited resources such as nurses and providers. Also, an efficient health system seeks short wait times for the patients to see the provider (indirect wait time) and within the clinic ...

Second-Order Conic Programming Approach for Wasserstein Distributionally Robust Two-Stage Linear Programs [PDF]
IEEE Transactions on Automation Science and Engineering, 2022 This paper proposes a second-order conic programming (SOCP) approach to solve distributionally robust two-stage stochastic linear programs over 1-Wasserstein balls. We start from the case with distribution uncertainty only in the objective function and exactly reformulate it as an SOCP problem. Then, we study the case with distribution uncertainty only

A two-stage sequential linear programming approach to IMRT dose optimization [PDF]
Physics in Medicine and Biology, 2010 The conventional IMRT planning process involves two stages in which the first stage consists of fast but approximate idealized pencil beam dose calculations and dose optimization and the second stage consists of discretization of the intensity maps followed by intensity map segmentation and a more accurate final dose calculation corresponding to ...
