This paper demonstrates the combined use of X-ray computed tomography (XCT), energy dispersive X-ray spectroscopy (EDX) and X-ray fluorescence (XRF) to evaluate the conservational history of the dentary (lower jaw) of Megalosaurus bucklandii Mantell, 1827, the first scientifically described dinosaur. Previous analysis using XCT revealed that the specimen had undergone at least two phases of repair...
X-ray Computed Tomography (CT) is a nondestructive evaluation method that gains recognition in dimensional metrology applications. During a CT scan, 2D radiographs are collected that are then reconstructed to a 3D model which allows non-destructive evaluation of the specimen and assists with the characterisations of defects. This technology has the potential to provide information unobtainable by...
Of key importance to any cultural institution is the practice of conservation, the method by which specimens at risk of severe degradation or destruction are treated to ensure that they survive into the future. However, surface inspection is often insufficient to properly inform conservators of the best treatment approach, and where there is little to no record of the conservational history of an...
In 1503, two ships part of Vasco da Gamas second armada to India were lost at sea. Archaeologists followed the historical trail that led them to the wreck site in Ghubbat ar Rahib Bay off Al Hallaniyah Island, Oman. The excavation found over 2800 artefacts including a ships bell and a concretion of silver coins. In this study the use of X-ray Computed Tomography (XCT) is outlined and how its exploitation...
This paper demonstrates a novel method that combines X-ray Computed Tomography (CT) and image processing for the investigation of bonded materials with significantly different densities. CT is increasingly used in aerospace applications for the inspection of materials and identification of defects. The limitations of the scanning process and data reconstruction methods are continuously being researched...
Virtual reality systems involve the integration of both hardware and software components. The hardware enables users to navigate, interact and become immersed in the virtual environment while underlying support software creates the virtual environment and integrates the hardware into a working system. Although virtual reality is widely used for product design visualisation in engineering, there exist...
