A comparison of uncertainty analysis methods for the modeling of land disposal of petroleum exploration and production waste
… (MC) simulation, (2) First-Order Second Moment (FOSM) method, and (3) Modified Point Estimate (MPE) method, were compared in terms of computational efficiency and accuracy for evaluation of contaminant concentration at a down-gradient receptor. Benzene and chloride, two contaminants most commonly …

On the uncertainty quantification and non-linear hyper elastic simulation of biological tissues
… examined using the First-Order Second-Moment (FOSM) method. Additionally, within Computational Fluid Dynamics (CFD) it is often necessary to adaptively move the mesh (e.g. moving boundary simulations, shape design optimization, generation of higher-order grids near curved boundaries, etc.). In …

An efficient technique for structural reliability with applications
… conjunction with the First Order Second Moment (FOSM) reliability method. The technique is applied when the limit state function cannot be obtained explicitly in terms of the design variables, i.e., when the analysis is performed using numerical techniques such as finite elements. The technique …

The probabilistic assessment of small homogeneous UK earthfill dams affected by climate change; Precipitation
… the First Order Second Moment method (FOSM) with the deterministic slope stability model with precipitation (ASMP) using sliding block formulation. For the purpose of this study, the selected precipitation scenarios (rainfall intensity and duration) are obtained from past Met Office …

Numerical modeling of a bridge system & its application for performance-based earthquake engineering
… diagrams. Then, First-Order Second-Moment (FOSM) analyses were performed to estimate parametric uncertainties. Gaussian stochastic random fields for clay and liquefiable soils were generated to investigate spatial variability uncertainties. Using the combined EDP uncertainties with IM hazard …

Uncertainty and Risk Analysis in Fire Safety Engineering
Two Quantitative Risk Analysis (QRA) methods are presented which can be used to quantify the risk to occupants in, for example, a building in which a fire has broken out. The extended QRA considers the inherent uncertainty in the variables explicitly. The standard QRA does not consider the …
