چکیده
In this study, the influence of different conservation methods for waterlogged archaeological wood (WAW) on non-destructive dendrochronological dating by micro-computed tomography (µCT) was evaluated. For purpose, samples species were conserved using following methods: alcohol-ether-resin, Kauramin 800®, lactitol/trehalose, saccharose, silicone oil and polyethylene glycol (PEG) treatments with subsequent freeze-drying. The tree ring measurements all in digital µCT data compared an analog linear measuring table terms total number rings per sample mean width. year-to-year width agreed very well overall corresponding microscopic measurements. It possible to detect cases.

Overall, study performed confirms that a powerful accurate method dendrochronology objects.

متن کاملComparison of phase contrast X-ray computed tomography methods for non-destructive testing of materials
Currently the basis for standard X-ray computed tomography (CT) is absorption. A volumetric map of a specimen in three dimensions is generated from a set of absorption radiographs. The contrast of details strongly depends on a difference in absorption coefficient between the detail and the environment. However, when the absorption difference is low, sufficient contrast for a good quality X-ray ...

Reverse engineering of electronics systems is performed for various reasons ranging from honest ones such as failure analysis, fault isolation, trustworthiness verification, obsolescence management, etc. to dishonest ones such as cloning, counterfeiting, identification of vulnerabilities, development of attacks, etc. Regardless of the goal, it is imperative that the research community understan...
متن کاملX-ray computed tomography.
X-ray computed tomography (CT), introduced into clinical practice in 1972, was the first of the modern slice-imaging modalities. To reconstruct images mathematically from measured data and to display and to archive them in digital form was a novelty then and is commonplace today. CT has shown a steady upward trend with respect to technology, performance and clinical use independent of predictio...
