Singularly perturbed problems with characteristic layers : Supercloseness and postprocessing
… to the standard Galerkin FEM. With a suitable postprocessing operator, the supercloseness property can be used to enhance the accuracy of the numerical solution and superconvergence of order (almost) two can be proved. We compare different postprocessing methods and prove superconvergence of …

A robust variable order facet model for image data
… approximation, an examination of the merits of postprocessing and tuning various parameters in the robust estimation procedures, and a new robust variable order facet model paradigm. Several new goodness of fit measures are introduced, and systematically compared. It is shown that the …

Inertial Manifolds and Nonlinear Galerkin Methods
… where a rough forcing term is used, a simple postprocessing step yields the same improvements that can be observed with nonlinear Galerkin. We show that this improvement is mainly due to the information about the forcing term that is neglected by standard Galerkin. Moreover, we construct a …

Bayesian Estimation for White Light Interferometry
… unifies the conventional steps of pre- and postprocessing within Bayesian inference. An adept formulation of the prior allows for the exact computation of the height estimate, obviating the need for stochastic sampling or simulation methods. In conventional surface estimation for white light …

Finite element modeling of the filament winding process using ABAQUS
… consists of the ABAQUS software and a pre/postprocessing routine that was developed to prepare necessary ABAQUS input files and process ABAQUS displacement results for stress and strain computation. The ABWACSAFE procedure has a structure and general flow pattern similar to the WACSAFE …

Development of a frequency-domain electromagnetic scattering measurement system
… was made using various size spheres, and the postprocessing outputs were compared to computed values. Good agreement between these measurements and computed data indicates excellent accuracy of the measurement system and valid operations of the postprocessing algorithm.

Refining inferred road maps using GANs
… improves tile consistency, and we introduce a postprocessing pipeline to further clean the graph. To evaluate these results, we focus on a state-of-the-art map inference method known as RoadTracer, published in 2018 by MIT and QCRI. We compare our refinement approach with the original …
