Global Analysis Of Linearized Inversion For The Acoustic Wave Equation by Cli ord J. Nolan To predict the location of natural resources and reduce the cost of exploration, geophysicists rely on various techniques to map the internal structure of the earth. One common mapping method probes the earth's interior using an acoustic energy source (sound waves). The acoustic waves re ect when they imp...

The scalar generalized-screen method in isotropic media is extended here to trans-versely isotropic media with a vertical symmetry axis (VTI). Although wave propaga-tion in a transversely isotropic medium is essentially elastic, we introduce an equiv-alent ‘acoustic’ system of equations for the qP-waves which we prove to be accuratefor both the dispersion relation and the po...

Delamination is one of the most concern defects in drilling of composite material. Delamination depends on the factors such as feed rate, tool geometry and wear. The mechanics of drilling composite materials has been examined along with the quality of the hole and the effect of tool design parameters. The capacity of computerized tomography (CT) showing sample cross-section in a nondestructive ...

ago, led to the reduction in habitat and the extinction or restriction of several species of beetles. Much later in the midnineteenth century, the arrival of Europeans and their cultivation practices modified the insect fauna of the American Midwest so profoundly that the event is as detectable in the fossil record as any ice age climate change. The lesson from the fossil record of insects is t...

This paper examines the inter-relationship between crisis planning and management and ethical decision making processes and practices as an example of building an interdisciplinary approach to crisis planning. The actions of the key organisations involved in the recent pharmaceutical product tampering cases in Australia are used to explore how responses during crisis correspond to both classica...
