Sensitivity analysis of upscaling prediction of the mass flux at DNAPL contaminated sites

地质科技通报, 2023
Dense nonaqueous phase liquid (DNAPL) contamination is a growing problem. To assess the environmental risk of DNAPL-contaminated sites, the mass flux of the dissolved phase (mass flux) in the source zone of DNAPL contamination is often extrapolated using

Global Sensitivity Analysis Applied to Train Traffic Rescheduling: A Comparative Study

Energies, 2021
The adjustment of rail traffic in the event of an electrical infrastructure disruption presents an important decision-making process for the smooth operation of the network. Railway systems are complex, and their analysis relies on expensive simulations,

Global sensitivity analysis of an end-to-end marine ecosystem model of the North Sea : factors affecting the biomass of fish and benthos [PDF]

, 2014
Comprehensive analysis of parameter and driver sensitivity is key to establishing the credibility of models of complex systems. This is especially so for models of natural systems where experimental manipulation of the real-world to provide controlled ...

A Global Sensitivity Analysis Framework for Hybrid Simulation [PDF]

Mechanical Systems and Signal Processing, 2021
Hybrid Simulation is a dynamic response simulation paradigm that merges physical experiments and computational models into a hybrid model. In earthquake engineering, it is used to investigate the response of structures to earthquake excitation. In the context of response to extreme loads, the structure, its boundary conditions, damping, and the ground ...

Global sensitivity analysis with dependence measures [PDF]

Journal of Statistical Computation and Simulation, 2014
Global sensitivity analysis with variance-based measures suffers from several theoretical and practical limitations, since they focus only on the variance of the output and handle multivariate variables in a limited way. In this paper, we introduce a new class of sensitivity indices based on dependence measures which overcomes these insufficiencies ...

Quantile-oriented global sensitivity analysis of design resistance

Journal of Civil Engineering and Management, 2019
The article investigates the application of a new type of global quantile-oriented sensitivity analysis (called QSA in the article) and contrasts it with established Sobol’ sensitivity analysis (SSA). Comparison of QSA of the resistance design value (0.1

Global Sensitivity Analysis for Optimization with Variable Selection [PDF]

SIAM/ASA Journal on Uncertainty Quantification, 2019
The optimization of high dimensional functions is a key issue in engineering problems but it frequently comes at a cost that is not acceptable since it usually involves a complex and expensive computer code. Engineers often overcome this limitation by first identifying which parameters drive the most the function variations: non-influential variables ...
