A global model for residential energy use: Uncertainty in calibration to regional data [PDF]

Energy, 2010
Uncertainties in energy demand modelling allow for the development of different models, but also leave room for different calibrations of a single model.

Determination of effective energies in CT calibration

Medical Physics, 1978
The effective energy of a polychromatic beam for a Computed Tomography (CT) scanner can be measured directly only with difficulty. However, a linear relationship exists between the measured CT numbers and corresponding attenuation coefficients of known materials at the effective energy of the x-ray beam.

Energy determination for electron beam calibration

Physics in Medicine and Biology, 1988
Presents the results of independent energy determinations, one by ion-chamber measurements in a water phantom, one by film analysis in a lucite phantom, and one by the ion-chamber response ratio described by the authors. The energy differences are insignificant with regard to the corresponding mass stopping power ratios needed for calibration.
