Non-destructive Investigation of the Dead Sea Scrolls
The Dead Sea Scrolls belong to the most important cultural assets of mankind. Their long term preservation and study is a challenge that demands an interdisciplinary approach. As early as the 1950s natural scientists assisted the scholars in studying the scrolls. It was at this time that the first extensive study of the scroll material took place. It was found that most fragments were written n...
متن کاملLeaf area estimation by a simple and non-destructive method
In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...
متن کاملContinuous-Wave Terahertz Spectroscopy as a Non-Contact Non- Destructive Method for Characterising Semiconductors
Using the technique of terahertz photomixing, a continuous-wave terahertz source is used to characterise various semiconductors in the frequency range from 0.06 to 1.0 THz. By directly analysing the interference pattern of the transmission through semiconductor wafers using Fabry-Pérot theory, information regarding the carrier concentration, sample thickness and refractive index is obtained wit...

15 صفحه اولA fictitious domain method for unilateral contact problems in non-destructive testing
In this work, we present a numerical method for solving the diffraction of transient elastic waves by cracks of arbitrary shapes in complex media, with Signorini’s boundary conditions on the crack. We use a fictitious domain method based on a mixed displacement–stress formulation for elastodynamics. We propose an off-centered time discretisation scheme for enforcing the stability.
