Multiscale Modeling of Process‐Induced Defects in Fused Filament Fabrication‐Printed Materials
Advanced Engineering Materials, EarlyView.This study presents a predictive multiscale modeling tool for defect analysis of fused filament fabricated‐printed materials and their performance prediction using a mechanistic data science‐based reduced‐order modeling approach. Process‐induced defects are inherent to additively manufactured parts and significantly influence the performance of printed

A Convex Reconstruction Model for X-ray Tomographic Imaging with Uncertain Flat-fields [PDF]
, 2017 Classical methods for X-ray computed tomography are based on the assumption that the X-ray source intensity is known, but in practice, the intensity is measured and hence uncertain.

Dark-field chest x-ray imaging: first experience in patients with alpha1-antitrypsin deficiency
European Radiology Experimental, 2022 Background Spirometry and conventional chest x-ray have limitations in investigating early emphysema, while computed tomography, the reference imaging method in this context, is not part of routine patient care due to its higher radiation dose.

Salt crystallization dynamics in building rocks: a 4D study using laboratory X-ray micro-CT [PDF]
, 2015 We employ laboratory X-ray micro-computed tomography (μCT) during climate-controlled salt weathering experiments to acquire data on the kinetics of drying and salt precipitation and the distribution of crystals within the pore space of Mšené sandstone ...

Advanced Engineering Materials, EarlyView.Additive manufacturing technologies like laser powder‐bed fusion offer great design freedom and individualization of products down to a batch size of one. However, parts fabricated with this technology suffer from poor quality. Acoustic assistance during the build process can minimize these drawbacks.
