Quantile-oriented global sensitivity analysis of design resistance

open access: yesJournal 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 Poverty Estimates: A Sensitivity Analysis

open access: yesIMF Working Papers, 2011
Current estimates of global poverty vary substantially across studies. In this paper we undertake a novel sensitivity analysis to highlight the importance of methodological choices in estimating global poverty. We measure global poverty using different data sources, parametric and nonparametric estimation methods, and multiple poverty lines.

Optimizing Genetic Circuits by Global Sensitivity Analysis [PDF]

open access: yesBiophysical Journal, 2004
Artificial genetic circuits are becoming important tools for controlling cellular behavior and studying molecular biosystems. To genetically optimize the properties of complex circuits in a practically feasible fashion, it is necessary to identify the best genes and/or their regulatory components as mutation targets to avoid the mutation experiments ...

Global Sensitivity Analysis of CASC2D Hydrological Model Parameters [PDF]

open access: yes长江科学院院报
[Objectives] The parameter calibration of the CASC2D hydrological model is mainly based on manual trial-and-error methods. It lacks a global sensitivity analysis of model parameters and the identification of relationships between parameters and ...

Global sensitivity analysis with dependence measures [PDF]

open access: yesJournal 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 ...

Sobol tensor trains for global sensitivity analysis [PDF]

open access: yesReliability Engineering & System Safety, 2019
Sobol indices are a widespread quantitative measure for variance-based global sensitivity analysis, but computing and utilizing them remains challenging for high-dimensional systems. We propose the tensor train decomposition (TT) as a unified framework for surrogate modeling and global sensitivity analysis via Sobol indices.

Global Dynamics of an Age-Structured Tuberculosis Model with Vaccine Failure and Nonlinear Infection Force

open access: yesAxioms, 2023
China bears a heavy burden due to tuberculosis (TB) with hundreds of thousands of people falling ill with the disease every year. Therefore, it is necessary to understand the effectiveness of current control measures in China.

Distribution‐Based Global Sensitivity Analysis in Hydrology [PDF]

open access: yesWater Resources Research, 2019
AbstractGlobal sensitivity analysis (GSA) is routinely used in academic setting to quantify the influence of input variability and uncertainty on predictions of a quantity of interest. Practical applications of GSA are hampered by its high computational cost, which arises from the need to run large (e.g., groundwater) models multiple times, and by its ...
