Nonparametric 3D map of the IGM using the Lyman-alpha forest
, 2014 Visualizing the high-redshift Universe is difficult due to the dearth of available data; however, the Lyman-alpha forest provides a means to map the intergalactic medium at redshifts not accessible to large galaxy surveys.

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Improvement and Unification of Input Images for Photogrammetric Reconstruction
Computer Assisted Methods in Engineering and Science, 2020 In this paper, we compare techniques for 3D reconstruction from images. We focus on the pre-processing step of reconstruction: improving the input images. Several image processing algorithms are selected and tested.

Learning quadrangulated patches for 3D shape parameterization and completion
, 2017 We propose a novel 3D shape parameterization by surface patches, that are oriented by 3D mesh quadrangulation of the shape. By encoding 3D surface detail on local patches, we learn a patch dictionary that identifies principal surface features of the ...

X‐Ray Tomography Analysis of Damage Mechanisms in Metal Matrix Syntactic Foams During Compression
Advanced Engineering Materials, EarlyView.In situ synchrotron X‐ray tomography is used to investigate the internal damage mechanisms of AlSi12 metal matrix syntactic foam with ceramic hollow spheres during compressive loading. It is concluded that a homogeneous distribution of the second‐phase filler material results in a sequential collapse in a localized region; this leads to controlled and ...

3D Scanning System for Automatic High-Resolution Plant Phenotyping
, 2016 Thin leaves, fine stems, self-occlusion, non-rigid and slowly changing structures make plants difficult for three-dimensional (3D) scanning and reconstruction -- two critical steps in automated visual phenotyping.
