Modelling South African currency crises as structural changes in the volatility of the rand
Duncan A.S.; Liu G.D. - 2009
This study tests the theory that currency crises are associated with sudden large changes in the structure of foreign exchange market volatility. Due to increases in market uncertainty, crisis periods exhibit abnormally high levels of volatility. By studying short-term changes in volatility...

Uncertainties in environmental radiological assessment models and their implications
Hoffman, F.O.; Miller, C.W. - 2008
uncertainty are related to biases in model formulation and parameter estimation. The best approach for estimating the actual … extent of over- or underprediction is model validation, a procedure that requires testing over the range of the intended … realm of model application. Other approaches discussed are the use of screening procedures, sensitivity and stochastic …

Beryllium-10: Half-life and AMS-standards
Hofmann, H.J.; Beer, J.; Bonani, G.; von Gunten, H.R.; … - 2008
Absolute AMS measurements of /sup 10/Be require reliable standards for calibration. Among the existing standards, rather large differences have been observed. These differences were found partially to be due to the different half-life values which were assumed. Also for comparison of AMS data...
