An Investigation of Quantifying and Monitoring Stone Surface Deterioration Using Three Dimensional Laser Scanning
Three dimensional laser scanning is considered to be the next generation of documentation methods, however the cost of these technologies remains extremely high and there are both known and unknown limitations of their application. This thesis, therefore, investigates the strengths and weaknesses …

Geometry-driven filamentary structures : elastic gridshells, weaves, clasps, and knots
… and advanced imaging techniques (e.g., 3D laser scanning, and X-ray computed tomography). First, we study the shape and the mechanical response of elastic gridshells, the three-dimensional structure of which results from the out-of-plane buckling of an initially flat and biaxial network …

Extraction of Structural Component Geometries in Point Clouds of Metal Buildings
… propose a framework built on the processing of 3D laser scanning data to partially automate the creation of these models. We focus on steel structures, as they represent a gap in current research into this field. Previous research has focused on segmentation of the point cloud data in order to …

Investigation of Linear and Nonlinear Torsional Guided Waves in Hollow Circular Cylinders for Damage Detection
… the experimental results and three-dimensional (3D) finite element (FE) simulations. Nonlinear guided wave is highly sensitive to early stage of micro cracks. Material nonlinearity is one of the nonlinear phenomena in the presence of the micro cracks. It can induce higher-order harmonics of …

Methods for the analysis of low-Z plasma facing surfaces in magnetic fusion applications
… morphology in each tile were mapped using a 3D laser scanning confocal microscope. Similar to the pure low-Z coatings used in the NSTX-U device, tin-lithium is a low melting-point eutectic that has been identified as a material with favorable performance in plasma material interaction (PMI) …

Examination of the forensic engineering techniques employed on fire-damaged concrete structures
… colour change, rebound hammer, UPV, portable 3D laser scanning and micro CT scanning. Finally, a set of test concrete mixtures most closely linked to those used in construction in the UAE were exposed to a real fire and were analysed post fire using a reduced set of the analytical techniques. …
