We present finite-element numerical simulations of seismic wave propagation in non linear inelastic geological media. We demonstrate the feasibility of large-scale modeling based on an implicit numerical scheme and a nonlinear constitutive model. We illustrate our methodology with an application to regional scale modeling in the French Riviera, which is(More)
9 Large-scale landslide prediction is typically based on numerical modelling, with computer 10 codes generally involving a large number of input parameters. Addressing the influence of 11 each of them on the final result and providing a ranking procedure may be useful for risk 12 management purposes. This can be performed by a variance-based global(More)
The Bundesamt für Strahlenschutz (Berlin, Germany) and the Paul Scherrer Institute (Villigen, Switzerland) both operate accredited calibration laboratories for radon gas activity concentration. Both the institutions use Lucas Cells as detector in their reference instrumentation due to the low dependence of this detector type on variations in environmental(More)
PREdiction of NOn-LINear soil behavior (PRENOLIN) is an international benchmark aiming to test multiple numerical simulation codes that are capable of predicting nonlinear seismic site response with various constitutive models. One of the objectives of this project is the assessment of the uncertainties associated with nonlinear simulation of 1D site(More)
This paper analyses the data having been gathered from interlaboratory comparisons of passive radon instruments over 10 y with respect to the measurement accuracy. The measurement accuracy is discussed in terms of the systematic and the random measurement error. The analysis shows that the systematic measurement error of the most instruments issued by(More)

Since 2003, the German Federal Office for Radiation Protection (BfS) has conducted annual interlaboratory comparisons for passive radon measuring devices in order to ensure the quality of these measurements. Passive radon devices which use solid state nuclear track detectors, electrets or activated charcoal can be tested. The exposures of radon devices are(More)
