Accelerated Bayesian experimental design for chemical kinetic models
(Massachusetts Institute of Technology, 2010)The optimal selection of experimental conditions is essential in maximizing the value of data for inference and prediction, particularly in situations where experiments are time-consuming and expensive to conduct. A general ... -
Accelerated computational modeling of ballistic helmet test protocols
(Massachusetts Institute of Technology, 2017)In modern combat, helmets play a vital role in protecting the head. Before being delivered to the soldier, combat helmets undergo a series of tests to determine their threat mitigation performance. During ballistic testing, ... -
