Reservoir Simulator Runtime Enhancement Based on a Posteriori Error Estimation Techniques
Oil & Gas Science and Technology, 2016 In this work, we show how the a posteriori error estimation techniques proposed in [Di Pietro et al. (2014) Computers & Mathematics with Applications 68, 2331-2347] can be efficiently employed to improve the performance of a compositional reservoir ...

Development and Validation of Open-Source R Package HMCtdm for Therapeutic Drug Monitoring
Pharmaceuticals, 2022 Most therapeutic drug monitoring (TDM) packages are based on the maximum a posteriori (MAP) estimation. In this study, HMCtdm, a new TDM package, was developed using a Hamiltonian Monte Carlo (HMC) simulation.

A Posteriori Error Estimates for Pressure-Correction Schemes [PDF]
SIAM Journal on Numerical Analysis, 2016 Summary: A posteriori error estimates for time discretization of the incompressible Stokes equations by pressure-correction methods are presented. We rigorously prove global upper bounds for the incremental backward Euler scheme as well as for the two-step backward differential formula method (BDF2) in rotational form.

A Posteriori Error Estimates for Domain Decomposition Methods
, 2023 Nowadays, a posteriori error control methods have formed a new important part of the numerical analysis. Their purpose is to obtain computable error estimates in various norms and error indicators that show distributions of global and local errors of a particular numerical solution.
