Augury and Forerunner: Real‐Time Feedback Via Predictive Numerical Optimization and Input Prediction

open access: yesComputer Graphics Forum, EarlyView.
Transient information generated by solver steps can inform future objective function minimization. In Augury, we explore the impact of predictive numerical optimization by using solver history to predict future minimization solutions, reducing computational resources needed to arrive at convergent states for a broad class of gradient‐based optimization

Anticipating the winds of change: A baseline assessment of Northeastern US continental shelf surficial substrates

open access: yesFisheries Oceanography, EarlyView.
Abstract The introduction of thousands of wind turbines along the North American Atlantic continental shelf over the next decade will constitute the largest regional change in marine substrates since the retreat of the Laurentide Ice Sheet over 14,000 years ago. Here, two large data sets, SMAST drop camera survey (242,949 samples, 2003 to 2019) and the

Uncertainty propagation and sensitivity analysis for constrained optimization of nuclear waste vitrification

open access: yesJournal of the American Ceramic Society, EarlyView.
Abstract The vitrification of high‐level waste (HLW) by heating a mixture of glass‐forming chemicals (GFCs) with the waste can be improved using a constrained optimization problem. This study explores how different uncertainty propagation (UP) methods implemented with the optimization process can affect the glass formulation of nuclear waste glasses ...

Sensemaking of Process Data from Evaluation Studies of Educational Games: An Application of Cross‐Classified Item Response Theory Modeling

open access: yesJournal of Educational Measurement, EarlyView.
Abstract Process information collected from educational games can illuminate how students approach interactive tasks, complementing assessment outcomes routinely examined in evaluation studies. However, the two sources of information are historically analyzed and interpreted separately, and diagnostic process information is often underused.

Vertical mergers without foreclosure

open access: yesJournal of Economics &Management Strategy, EarlyView.
Abstract The typical concern about vertical mergers is the foreclosure of downstream rivals. In a vertically related industry where downstream firms have a common supplier, margins can reveal whether upstream competition constrains that supplier.
