Markov chain Monte Carlo with Gaussian processes for fast parameter estimation and uncertainty quantification in a 1D fluid-dynamics model of the pulmonary circulation. [PDF]
Int J Numer Method Biomed Eng, 2021 Uncertainty quantification in a complex physiological model of the pulmonary circulation can be made computationally feasible by combining state‐of‐the‐art numerical Bayesian methods with statistical emulation using Gaussian Processes. A comparative assessment in terms of computational efficiency of several novel Bayesian (MCMC) algorithms identifies ...

Water Resources Research, Volume 59, Issue 12, December 2023., 2023 Abstract This article reviews the mathematical formulations of the depth‐integrated advection‐diffusion equation used so far for modeling scalar transport and mixing in shallow environmental flows. It also summarizes the main approaches developed to evaluate the diffusivity tensor in such models.

The Impact of Critical Flutter Velocity in Composite Wind Turbine Blade with Prebend Condition
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 The present work focuses on the effect of flutter in prebend 100 m horizontal axis wind turbine blade (HAWT) within the stability limits. The study was carried out with an advanced beam model for idyllic structure in a DU‐97‐W‐300 cross‐sectional area. A Galerkin type of approach has been applied to derive the equations, and the analysis was performed ...

Science and Technology of Nuclear Installations, Volume 2020, Issue 1, 2020., 2020 In this study, the Best Estimate Plus Uncertainty (BEPU) approach is developed for the systematic quantification and propagation of uncertainties in the modelling and simulation of lead‐cooled fast reactors (LFRs) and applied to the demonstration LFR (DLFR) initially investigated by Westinghouse. The impact of nuclear data uncertainties based on ENDF/B‐

Fully Parametric Optimization Designs of Wing Components
International Journal of Aerospace Engineering, Volume 2020, Issue 1, 2020., 2020 An optimization technique called shape‐linked optimization, which is different from the traditional optimization method, is introduced in this paper. The research introduces an updated wing optimization design in an effort to adapt to continuous structure changes and shapes while optimizing for a lighter weight of the structure. The changing tendencies

Quarterly Journal of the Royal Meteorological Society, Volume 144, Issue 713, Page 1218-1256, April 2018 Part B., 2018 Data assimilation methods for convective‐scale numerical weather prediction at operational centres are surveyed. It is demonstrated that the quality of forecasts based on initial data from convective‐scale data assimilation is significantly better than the quality of forecasts from simple downscaling.

Nanobeams and AFM Subject to Piezoelectric and Surface Scale Effects
Advances in Mathematical Physics, Volume 2018, Issue 1, 2018., 2018 Vibration dynamics of elastic beams that are used in nanotechnology, such as atomic force microscope modeling and carbon nanotubes, are considered in terms of a fundamental response within a matrix framework. The modeling equations with piezoelectric and surface scale effects are written as a matrix differential equation subject to tip‐sample general ...

Mathematical Problems in Engineering, Volume 2014, Issue 1, 2014., 2014 Modal Identification is considered from response data of structural systems under nonstationary ambient vibration. The conventional autoregressive moving average (ARMA) algorithm is applicable to perform modal identification, however, only for stationary‐process vibration.

Constraining 2D Hydrogeological Inversion With 3D Lithological Data
Water Resources Research, Volume 61, Issue 12, December 2025.Abstract In hydrogeology, piezometric data are the key constraints for model calibration. Their limits for three‐dimensional (3D) parameterization have often been pointed out, with water heads commonly regarded as having too little sensitivity to vertical heterogeneity.
