The Bayesian validation metric : a framework for probabilistic model calibration and validation
In model development, model calibration and validation play complementary roles toward learning reliable models. In this thesis, we propose and develop the "Bayesian Validation Metric" (BVM) as a general model validation and testing tool. We show that the BVM can represent all the standard …

Calibration and validation of honey bee foraging flight duration as an estimate of distance flown
Organic beekeeping standards require that beekeepers provide for their honey bees (Apis mellifera, L.) with a radius of 6.4 km of foraging land that is free from (3 km) or with reduced use of (additional 3.4 km) synthetic pesticides. This requirement is based on the honey bee's large maximum …

An Extended Calibration and Validation of a Slotted-Wall Transonic Wall-Interference Correction Method for the National Transonic Facility
… to a free-air condition. Accurately determining and correcting for the interference caused by the presence of boundaries in wind tunnels can be difficult especially for facilities employing ventilated boundaries. In this work, three varying levels of ventilation at the National Transonic Facility …
