The goal of this paper is to provide an overview of the current state of the art in seismic
tomography, and trace its origins from pioneering work in the early 1970s to its present …

The class of geometric deformable models, also known as level sets, has brought
tremendous impact to medical imagery due to its capability of topology preservation and fast …

Routine seismic monitoring in mines was introduced over 30 years ago with two main
objectives in mind:• immediate location of larger seIsmIC events to guide rescue operations;• …

Seismic data represent one of the most valuable resources for investigating the internal
structure and composition of the earth. One of the first people to deduce earth structure from …

Numerical simulation of high frequency acoustic, elastic or electro-magnetic wave
propagation is important in many applications. Recently the traditional techniques of ray …

We present a practical grid-based method in 3-D spherical coordinates for computing
multiple phases comprising any number of reflection and transmission branches in …

ABSTRACT A unified approach to approximating phase and group velocities of qP seismic
waves in a transversely isotropic medium with vertical axis of symmetry (VTI) is developed …

Publisher Summary This chapter describes a variety of schemes for tracking the kinematic
evolution of high frequency seismic waves in heterogeneous 2-D and 3-D structures. Where …

Lattice structures are increasingly used in practical engineering due to their excellent
mechanical properties such as light weight, high load-bearing capacity, and high ductility. In …
