The VFSMOD-W can predict hydrology and sediment transport well (Nash Sutcliffe coefficient of efficiency >0.6) for calibration and validation events with peak outflow rate from VFS greater than 0.0004 m3/s.
The calibration PCR and PLS-1 models were evaluated by internal validation (prediction of compounds in its own designed training set of calibration), by cross-validation (obtaining statistical parameters that show the efficiency for a calibration fit model) and by external validation over laboratory-prepared mixtures and pharmaceutical preparations.
The calibration PLS-1 and PCR models were evaluated by internal validation (prediction of compounds in its own designed training set of calibration), by cross-validation (obtaining statistical parameters that show the efficiency for a calibration fit model) and by external validation over synthetic and pharmaceutical preparation.
These calibration models were evaluated by internal validation (prediction of compounds in its own designed training set of calibration), by cross-validation (obtaining statistical parameters that show the efficiency for a calibration fit model) and by external validation over synthetic and pharmaceutical mixtures.
Because of different slopes in the calibration methods, it was also found that the limitation values for some components from the internal standard were higher than from external standard calibration, because in the latter a factor for injection efficiency is applied for calibration.
The SWAT model performance was in satisfactory agreement with the Nash Sutcliff efficiency values of 0.88 and 0.82 for calibration and validation, respectively.
Estimated drain flow using the Hooghoudt equation with measured water table height for both free draining and controlled periods compared well to observed flow with Nash-Sutcliffe Efficiency values above 0.7 and 0.8 for calibration and validation periods, respectively.
We present the new improved version of our Monte Carlo program DETEFF for detector efficiency calibration in gamma-ray spectrometry.
These results and those obtained during the application of the previous versions indicate the program's suitability as a tool for the efficiency calibration of coaxial gamma-ray detectors, especially in routine measurements such as environmental monitoring.
As a result, applicability and performance of the air2stream model for a particular stream relies on the efficiency of the calibration method.
Moreover, in between consecutive calibration measurements, there is no guarantee that the respective PET system does not exhibit a certain drift in efficiency for assorted reasons, potentially invalidating the given calibration [7].
