We systematically compare an event-by-event heavy-ion collision model to data from the CERN Large Hadron Collider. Using a general Bayesian method, we probe multiple parameters including fundamental quark-gluon plasma properties such as specific shear viscosity $\ensuremath{\eta}/s$, calibrate optimally reproduce experimental data, and extract quantitative constraints for all simultaneously. The method is universal easily extensible other models.
New measurement and assessment techniques have been applied to the radiochemical reevaluation of Trinity Event. Thirteen trinitite samples were dissolved analyzed using a combination traditional decay counting methods mass spectrometry techniques. The resulting data assessed advanced simulation tools afford final yield determination 24.8 ± 2 kt TNT equivalent, substantially higher than previous U.S. Department Energy released value 21 kt.
Abstract Part 1 of this paper presents a numerical model for non‐reactive physical mass transfer across wetted wall column (WWC). In 2, we improved the existing computational fluid dynamics (CFD) to simulate chemical absorption occurring in WWC as bench‐scale study solvent‐based carbon dioxide (CO 2 ) capture. To generate data validation, CO monoethanolamine (MEA) solvent was first measured on experimental apparatus. The developed work can account both and desorption MEA. addition, overall...
Substantial research has demonstrated that an external (vs. internal) attentional focus enhances motor performance among various populations. Interest recently grown in examining the effects of individuals with visual impairments (VI), and, to date, results have been conflicting some studies supporting a potential benefit adults VI, while study children severe VI was inconclusive regarding this benefit. The present investigation compared internal versus on discrete throwing task adolescents...
Abstract A hierarchical model calibration and validation are proposed for quantifying the confidence level of mass transfer prediction using a computational fluid dynamics (CFD) model, where solvent‐based carbon dioxide (CO 2 ) capture is simulated predicted results compared to corresponding bench‐scale experimental data. Two unit problems with an increasing complexity break down complex physical/chemical processes CO into relatively simpler separate effects physical transport chemical...
Oxy-fired coal combustion is a promising potential carbon capture technology. Predictive computational fluid dynamics (CFD) simulations are valuable tools in evaluating and deploying oxyfuel other technologies, either as retrofit technologies or for new construction. However, accurate predictive combustor require physically realistic submodels with low requirements. A recent sensitivity analysis of detailed char conversion model (Char Conversion Kinetics (CCK)) found thermal annealing to be...
Abstract For industrial-scale CO2 injection in saline formations, produced and pressure buildup can limit storage capacity efficiency. Sensitivity analysis on operational strategies reservoir parameters serves to select the optimum strategy increase injectivity, relieve buildup, improve trapping efficiency, constrain brine leakage. In this paper, we developed a surrogate model for aquifers Tensleep Formation based features of at Teapot Dome Wyoming. The corresponding oil was history-matched...
Over the last decade, a series of applied mathematics papers have explored type inverse problem--called by variety names including "inverse sensitivity", "pushforward based inference", "consistent Bayesian or "data-consistent inversion"--wherein solution is probability density whose pushforward takes given form. The formulation such stochastic problem can be unexpected confusing to those familiar with traditional otherwise statistical inference. To date, two classes solutions been proposed,...
The equations of a physical constitutive model for material stress within tantalum grains were solved numerically using tetrahedrally meshed volume. resulting output included scalar vonMises each the more than 94,000 tetrahedra finite element discretization. In this paper, we define an intricate statistical spatial field which uses given grain geometry in fundamental way. Our relates three-dimensional to integrals latent stochastic processes defined on vertices one- and two-dimensional...
There are many practical difficulties in the calibration of computer models to experimental data. One such complication is fact that certain combinations inputs can cause code output data lacking fundamental properties, or even produce no at all. In cases researchers want need exclude possibility these "failures" within their analyses. We propose a Bayesian (meta-)model which posterior distribution for parameters naturally excludes regions input space corresponding failed runs. That is, we...
