Precise determination of HPGe detector efficiency for gamma spectrometry measurements of environmental samples with variable geometry and density

open access: yesNukleonika, 2017
A methodology to determine the full energy peak efficiency (FEPE) for precise gamma spectrometry measurements of environmental samples with high-purity germanium (HPGe) detector, valid when this efficiency depends on the energy of the radiation E, the ...

Efficient Calibration for Decision Making

open access: yesProceedings of the 58th Annual ACM Symposium on Theory of Computing
A decision-theoretic characterization of perfect calibration is that an agent seeking to minimize a proper loss in expectation cannot improve their outcome by post-processing a perfectly calibrated predictor. Hu and Wu (FOCS'24) use this to define an approximate calibration measure called calibration decision loss ($\mathsf{CDL}$), which measures the ...

On optimization of calibrations of a distributed hydrological model with spatially distributed information on snow [PDF]

open access: yesHydrology and Earth System Sciences
In northern cold-temperate countries, a large portion of annual streamflow is produced by spring snowmelt, which often triggers floods. It is important to have spatial information about snow variables such as snow water equivalent (SWE), which can be ...
