Cross-Validation of Generic Risk Assessment Tools for Animal Disease Incursion Based on a Case Study for African Swine Fever

open access: yesFrontiers in Veterinary Science, 2020
In recent years, several generic risk assessment (RA) tools have been developed that can be applied to assess the incursion risk of multiple infectious animal diseases allowing for a rapid response to a variety of newly emerging or re-emerging diseases ...

Climate model uncertainty versus conceptual geological uncertainty in hydrological modeling [PDF]

open access: yesHydrology and Earth System Sciences, 2015
Abstract. Projections of climate change impact are associated with a cascade of uncertainties including in CO2 emission scenarios, climate models, downscaling and impact models. The relative importance of the individual uncertainty sources is expected to depend on several factors including the quantity that is projected.

On hedging American options under model uncertainty

open access: yes, 2015
We consider as given a discrete time financial market with a risky asset and options written on that asset and determine both the sub- and super-hedging prices of an American option in the model independent framework of ArXiv:1305.6008.

Managing structural uncertainty in health economic decision models: a discrepancy approach [PDF]

open access: yes, 2012
Healthcare resource allocation decisions are commonly informed by computer model predictions of population mean costs and health effects. It is common to quantify the uncertainty in the prediction due to uncertain model inputs, but methods for ...

Quantifying Correlation Uncertainty Risk in Credit Derivatives Pricing

open access: yesInternational Journal of Financial Studies, 2018
We propose a simple but practical methodology for the quantification of correlation risk in the context of credit derivatives pricing and credit valuation adjustment (CVA), where the correlation between rates and credit is often uncertain or unmodelled ...

A Tight High-Order Entropic Quantum Uncertainty Relation With Applications [PDF]

open access: yes, 2006
We derive a new entropic quantum uncertainty relation involving min-entropy. The relation is tight and can be applied in various quantum-cryptographic settings.

CO2 plume evolution in a depleted natural gas reservoir: Modeling of conformance uncertainty reduction over time [PDF]

open access: yes, 2020
Uncertainty in the long-term fate of CO2 injected for geologic carbon sequestration (GCS) is a significant barrier to the adoption of GCS as a greenhouse-gas emission-mitigation for industry and regulatory agencies alike. We present a modeling study that

Comparing Kalman Filters and Observers for Power System Dynamic State Estimation With Model Uncertainty and Malicious Cyber Attacks

open access: yesIEEE Access, 2018
Kalman filters (KFs) and dynamic observers are two main classes of the dynamic state estimation (DSE) routines. The Power system DSE has been implemented by various KFs, such as the extended KF (EKF) and the unscented KF (UKF).

Nested models and model uncertainty [PDF]

open access: yes
Uncertainty about the appropriate choice among nested models is a central concern for optimal policy when policy prescriptions from those models differ. The standard procedure is to specify a prior over the parameter space ignoring the special status of ...

A Model-Based Reliability Metric Considering Aleatory and Epistemic Uncertainty

open access: yesIEEE Access, 2017
Model-based reliability analysis and assessment methods rely on models, which are assumed to be precise, to predict reliability. In practice, however, the precision of the model cannot be guaranteed due to the presence of epistemic uncertainty.
