Amplitude and Phase Fluctuations in Ultrasonic Waves Propagating in Inhomogeneous Materialshe wave analysis. In the former, it is the fact that the flaw is usually . isolated scattering structure. In the latter, simplification comes from the use of thin specimens or focal zones which thus essentially reduce the problem to a two-dimensional one. The concern in the present work is with the

Cryogenic Acoustic Microscopy. During this period we have seen the development of infrared microscopy (3), scanning Auger microscopy (4), Raman microscopy (5), scanning laser microscopy (6), ion microscopy (7), X-Ray microscopy (8), tunnelling microscopy (9) and the list seems to be growing every year. All of these microscopes

Characterisation of Microstructures Using Ultrasonicsic velocity measurements at a single frequency, the determination of the above mentioned properties requires the measurement of the frequency dependence of the velocity or attenuation. A recent application is the prediction of yield strength in plain carbon steel using an ultrasonic determination of

Analysis of Signals Generated by Multiply Reflected Ultrasonic Waves in Plateseement is observed between the experimental and theoretical magnitudes of individual nonoverlapping tone burst reflections. It is observed theoretically and experimentally that the magnitude spectra of individual nonoverlapping pulse reflections have approximately the same characteristics as the mag

al seepage can be severely hindered by the ascent of volcanic gases, whereas horizontal infiltration through the vertical lake walls may ensure a long-term water loss. Our simulations also show that the permeability distribution, especially around the lake, determines the overall pattern of circulat

Contrarily, after the Early Miocene the basalts corresponded to a retro-arc environment installed by the Nazca Plate subduction. Besides, from the

The subcrustal earthquakes have mechanisms which are consistent with one another and these show nearly pure strike slip faulting, with NE oriented P axes. The focal mechanisms of the subcrustal events, coupled with the general SW-NE alignment of the volc
