Model Bias Identification for Bayesian Calibration of Stochastic Digital Twins of Bridges

Applied Stochastic Models in Business and Industry, EarlyView.
ABSTRACT Simulation‐based digital twins must provide accurate, robust, and reliable digital representations of their physical counterparts. Therefore, quantifying the uncertainty in their predictions plays a key role in making better‐informed decisions that impact the actual system.

The Grushin plane and quasiconformal Jacobians [PDF]

arXiv, 2011
We construct a quasiconformal map from the Grushin plane to the Euclidean plane. Then, we generalize the Grushin plane slightly and explain how the Grushin plane can serve as an intermediary in dealing with quasiconformal maps on Euclidean spaces. In particular, we construct a family of quasiconformal embeddings of the Euclidean plane into larger ...

Three‐dimensional assessment of subchondral arc and hip joint coverage angles in the asymptomatic young adult hip

Clinical Anatomy, EarlyView.
Abstract The primary objective of this study was to develop a custom algorithm to assess three‐dimensional (3D) acetabular coverage of the femoral head based on surface models generated from computed tomography (CT) imaging. The secondary objective was to apply this algorithm to asymptomatic young adult hip joints to assess the regional 3D acetabular ...

MoebInv: C++ libraries for manipulations in non-Euclidean geometry

SoftwareX, 2020
The introduced package MoebInv contains two C++ libraries for symbolic, numeric and graphical manipulations in non-Euclidean geometry. The first library cycle implements basic geometric operations on cycles, which are the zero sets of certain polynomials

Bi-Lipschitz Quotient embedding for Euclidean Group actions on Data [PDF]

arXiv
For the action of the orthogonal group or euclidean group on k-tuples of vectors we construct a bi-Lipschitz embedding from the orbit space into euclidean space.This embedding has distortion sqrt(2).

Practical assessment of masonry tunnel joint segmentation using topological machine learning

Civil Engineering Design, EarlyView.
Abstract Condition assessment of masonry lined tunnels is time consuming and labor intensive. Recently developed digital workflows enable structural models to be created automatically, reducing analysis time. As part of these procedures, it is important to be able to identify the location of each masonry block.
