Avalanche models are increasingly employed for elaborating land-use maps and designing defense structures, but they rely on poorly known parameters. Careful uncertainty assessment is thus required difficulty arises from the nature of outputs these models, which commonly both functional scalar. Hence, so far in avalanche field, few sensitivity analyses have been performed. In this work, we propo...

LCA has been extensively used in the last few years and a large number of studies have been published in the literature. These studies show a great variability in results of comparable systems. It somehow leads policy-makers to consider the LCA approach as an inconclusive method. Some attempts have been developed to assess LCA results variability; however, they remain mostly qualitative. In thi...

A parametric sensitivity analysis is carried out on GASCON, a radiological impact software describing the radionuclides transfer to the man following a chronic gas release of a nuclear facility. An effective dose received by age group can thus be calculated according to a specific radionuclide and to the duration of the release. In this study, we are concerned by 18 output variables, each depen...

Communities and their supporting civil infrastructure systems can be viewed as an assembly of, often numerous, interacting, interdependent components. Tools that identify rank the components relevant for community disaster resilience help efficiently allocate limited resources to reach goals. We propose a method based on Sobol’ indices heuristic upper lower bound search measure importance of vu...

Bridge deterioration is affected by various factors. However, neither the relationships between these factors and are explicitly determined, nor relative effect of each factor on well understood. This study proposed a methodology to resolve issues integrating an artificial neural network (ANN) sensitivity analysis method. The ANN was used predict deterioration, method applied evaluate influence...

Nuclear grade axial flow fans are widely used in nuclear power plants for ventilation and heat dissipation have the advantages of high efficiency rates. A fan with OGVs (outlet guide vanes) can recover kinetic energy dynamic impeller outlet winding to increase ventilator pressure, thus improving efficiency; therefore, play an essential role performance fan. Based on accurate numerical simulatio...
