Estimating actual evapotranspiration from an alpine grassland on Qinghai-Tibetan plateau using a two-source model and parameter uncertainty analysis by Bayesian approach
Bayesian statistics Evapotranspiration Shuttleworth–Wallace model Alpine grassland Qinghai-Tibetan plateau
2013/9/2
A Bayesian method was used to fit the Shuttleworth–Wallace model to half-hourly measurements ofevapotranspiration (ET) with the eddy covariance technique from an alpine grassland on the Qinghai-Tibeta...
The effect of parameter uncertainty on achieved safety integrity of safety system
Safety system Importance measure Safety-related uncertainty Global sensitivity analysis Safety integrity level
2012/4/22
This paper introduces the concept of safety-related (SR) uncertainty and the methodology to measure SR uncertainty. SR uncertainty is concerned with the effect of parameter uncertainty on the uncertai...
Reconstruction of signals with unknown spectra in information field theory with parameter uncertainty
Reconstruction signals unknown spectra information field theory parameter uncertainty
2010/3/11
The optimal reconstruction of cosmic metric perturbations and other signals requires knowledge
of their power spectra and other parameters. If these are not known a priori, they have to be
measured ...
Multi-parameter uncertainty analysis of a bifurcation point
Multi-parameter uncertainty analysis bifurcation point
2009/11/9
Parameter uncertainty analysis of climate models has become a standard approach for model validation and testing their sensitivity. Here we present a novel approach that allows one to estimate the rob...
Estimation of Parameter Uncertainty in the HBV Model
Estimation of Parameter Uncertainty HBV Model
2009/10/23
Usually the HBV model is calibrated by seeking one optimal parameter set that
represents the catchment. From experience we know, however, that it is hardly
poss~ble to find an unique parameter set. ...
A novel approach to parameter uncertainty analysis of hydrological models using neural networks
hydrological models neural networks Artificial Neural Network
2009/7/22
In this study, a methodology has been developed to emulate a time consuming Monte Carlo (MC) simulation by using an Artificial Neural Network (ANN) for the assessment of model parametric uncertainty. ...
LGD credit risk model: estimation of capital with parameter uncertainty using MCMC
LGD credit risk model capital parameter MCMC
2010/12/13
This paper investigates the impact of parameter uncertainty on capital estimate in the well-known extended Loss Given Default (LGD) model with systematic dependence between default and recovery. We de...
Estimation of Operational Risk Capital Charge under Parameter Uncertainty
quantitative risk management operational risk loss distribution approach
2010/10/29
Many banks adopt the Loss Distribution Approach to quantify the operational risk capital
charge under Basel II requirements. It is common practice to estimate the capital charge
using the 0.999 quan...
Addressing the Impact of Data Truncation and Parameter Uncertainty on Operational Risk Estimates
operational risk truncated data Poisson-Lognormal compound distribution loss distribution approach
2010/11/1
Typically, operational risk losses are reported above some threshold. This paper studies the
impact of ignoring data truncation on the 0.999 quantile of the annual loss distribution for
operational ...

Investigation of parameter uncertainty and identifiability of the hydrological model WaSiM-ETH
parameter uncertainty and identifiability the hydrological model WaSiM-ETH
2010/1/26
The identification of optimum model parameters may be influenced by temporal or event-specific changes of optimum parameter ranges and the length and information content of calibration data. These eff...
