The Impact of a Regional Nuclear Conflict between India and Pakistan: Two Views

open access: yesJournal for Peace and Nuclear Disarmament, 2021
The severity of climatic effects of a regional nuclear conflict between India and Pakistan, involving the use of a hundred Hiroshima-scale nuclear weapons, is contested between two groups; Mills et al.

Comparison of Deterministic and Probabilistic Variational Data Assimilation Methods Using Snow and Streamflow Data Coupled in HBV Model for Upper Euphrates Basin

open access: yesGeosciences, 2023
The operation of upstream reservoirs in mountainous regions fed by snowmelt is highly challenging. This is partly due to scarce information given harsh topographic conditions and a lack of monitoring stations. In this sense, snow observations from remote

Effects of precipitation uncertainty on discharge calculations for main river basins [PDF]

open access: yes, 2009
This study quantifies the uncertainty in discharge calculations caused by uncertainty in precipitation input for 294 river basins worldwide. Seven global gridded precipitation datasets are compared at river basin scale in terms of mean annual and ...

Bayesian Model Averaging and Prior Sensitivity in Stochastic Frontier Analysis

open access: yesEconometrics, 2020
This paper discusses Bayesian model averaging (BMA) in Stochastic Frontier Analysis and investigates inference sensitivity to prior assumptions made about the scale parameter of (in)efficiency. We turn our attention to the “standard” prior specifications

Probabilistic Models for the Shear Strength of RC Deep Beams

open access: yesApplied Sciences, 2023
A new shear strength determination of reinforced concrete (RC) deep beams was proposed by using a statistical approach. The Bayesian–MCMC (Markov Chain Monte Carlo) method was introduced to establish a new shear prediction model and to improve seven ...

Dasymetric Modeling and Uncertainty [PDF]

open access: yesAnnals of the Association of American Geographers, 2013
Dasymetric models increase the spatial resolution of population data by incorporating related ancillary data layers. The role of uncertainty in dasymetric modeling has not been fully addressed as of yet. Uncertainty is usually present because most population data are themselves uncertain, and/or the geographic processes that connect population and the ...

Improving Re-Identification by Estimating and Utilizing Diverse Uncertainty Types for Embeddings

open access: yesAlgorithms
In most re-identification approaches, embedding vectors are compared to identify the best match for a given query. However, this comparison does not take into account whether the encoded information in the embedding vectors was extracted reliably from ...

Hands-on MPC Tuning for Industrial Applications [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2019
This paper proposes a practical tuning of closed loops with model based predictive control. The data assumed to be known from the process is the result of the bump test commonly applied in industry and known in engineering as step response data.

An Adaptive Tracking-Extended Kalman Filter for SOC Estimation of Batteries with Model Uncertainty and Sensor Error

open access: yesEnergies, 2022
Accurate state of charge (SOC) plays a vital role in battery management systems (BMSs). Among several developed SOC estimation methods, the extended Kalman filter (EKF) has been extensively applied.

Great uncertainties in modeling grazing impact on carbon sequestration: a multi-model inter-comparison in temperate Eurasian Steppe

open access: yesEnvironmental Research Letters, 2018
The impact of grazing activity on terrestrial carbon (C) sequestration has been noticed and studied worldwide. Recent efforts have been made to incorporate the disturbance into process-based land models. However, the performance of grazing models has not
