Uncertainties in tree-ring-based climate reconstructions probed
Uncertainties tree-ring-based climate reconstructions
2016/2/22
Current approaches to reconstructing past climate by using tree-ring data need to be improved on so that they can better take uncertainty into account, new University of Otago-led suggests.Tree growth...
It is shown that robust stability and robust performance questions for control systems with nonparametric uncertainties can be turned into those with a particularly simple parametric description. It i...
Quantifying Uncertainties in Ocean Predictions
Ocean Predictions Quantifying Uncertainties
2015/7/23
A multitude of physical and biological processes occur in the ocean over a wide range of temporal and spatial scales. Many of these processes are nonlinear and highly variable, and involve interaction...
Design of DOE-based Automatic Process Controller with Consideration of Model Uncertainties
Automatic Process Controller Model Uncertainties
2015/3/18
This paper developed a DOE-based
automatic process control scheme considering both
observation and modeling uncertainties. The
simulation demonstrates that considering the
uncertainties, automatic...
“Probabilistic calibration of a Greenland Ice Sheet model using spatially resolved synthetic observations: toward projections of ice mass loss with uncertainties” published in Geosci. Model Dev., 7, 1933–1943, 2014
Greenland Ice Sheet spatially resolved synthetic observations
2014/12/19
Due to an oversight in the production process, the article “Probabilistic calibration of a Greenland Ice Sheet model
using spatially resolved synthetic observations: toward projections of ice mass lo...
Modeling sugarcane yield with a process-based model from site to continental scale: uncertainties arising from model structure and parameter values
Modeling sugarcane yield continental scale
2014/12/18
Agro-land surface models (agro-LSM) have been
developed from the integration of specific crop processes into
large-scale generic land surface models that allow calculating
the spatial distrib...
Uncertainties in estimating regional methane emissions from rice paddies due to data scarcity in the modeling approach
estimating regional methane emissions rice paddies
2014/12/18
Rice paddies are a major anthropogenic source
of the atmospheric methane. However, because of the high
spatial heterogeneity, making accurate estimations of the
methane emission from rice paddies i...

Development of an ensemble-adjoint optimization approach to derive uncertainties in net carbon fluxes
derive uncertainties net carbon fl uxes
2014/12/9
Accurate modelling of the carbon cycle strongly
depends on the parametrization of its underlying processes.
The Carbon Cycle Data Assimilation System (CCDAS) can
be used as an estimator algorithm t...
IUTAM Symposium - Dynamical Analysis of Multibody Systems with Design Uncertainties
IUTAM Symposium Dynamical Analysis of Multibody Systems with Design Uncertainties
2013/11/29
A common problem in the analysis of mechanical systems is the fact that the parameters of the models can exhibit a high level of uncertainty and exact values for their quantification can often not be ...

DAMA CoGeNT without astrophysical uncertainties
2011/10/18
The CoGeNT collaboration has reported evidence of an annual modulation in its first fifteen months of data. Here we compare the amplitude and phase of this signal to the modulation observed by the DAM...
We present a method to minimize, or even cancel out, the nuisance parameters affecting a measurement. Our approach is general and can be applied to any experiment or observation. We compare it with th...
