15 صفحه اولTheory of acoustic attenuation, dispersion, and pulse propagation in unconsolidated granular materials including marine sediments
A unified theory of sound propagation in saturated marine sediments is developed on the basis of a linear wave equation, which includes a new dissipation term representing internal losses arising from interparticle contacts. This loss mechanism, which shows a ‘‘memory’’ or hysteresis, is proposed as being responsible for the acoustic properties of sediments. To accommodate the memory, the loss ...
متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
