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 ...

Seismic Constraints on Interior Solar Convection [PDF]

open access: yes, 2010
We constrain the velocity spectral distribution of global-scale solar convective cells at depth using techniques of local helioseismology. We calibrate the sensitivity of helioseismic waves to large-scale convective cells in the interior by analyzing ...

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 ...

Moment-based metrics for global sensitivity analysis of hydrological systems [PDF]

open access: yesHydrology and Earth System Sciences, 2017
We propose new metrics to assist global sensitivity analysis, GSA, of hydrological and Earth systems. Our approach allows assessing the impact of uncertain parameters on main features of the probability density function, pdf, of a target model output,

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.

Asymptotic Analysis for the Variance-Based Global Sensitivity Indices

open access: yesScience and Technology of Nuclear Installations, 2012
We discuss the estimation of the uncertainty and sensitivity parameters for a model response under the assumption that the input variables are normally distributed and block-wise correlated with the covariance matrix, which is small in some norm.

Sobol\u27 sensitivity analysis of the Holocene Peat Model: What drives carbon accumulation in peatlands? [PDF]

open access: yes, 2013
Understanding the development of northern peatlands and their carbon accumulation dynamics is crucial in order to confidently integrate northern peatlands into global carbon cycle models.
