Modeling, inversion and imaging of seismic data in viscous media
Real Earth media is anelastic, which affects both kinematics and dynamics of propagating waves. Waves are attenuated and dispersed. If anelastic effects are neglected, inversion and migration can yield erroneous results. The ...
Dynamic multiple pattern matching
Pattern matching algorithms are among the most important and practical contribution of theoretical computer science. Pattern matching is used in a wide variety of applications such as text editing, information retrieval, ...
An efficient simplex-based method for solving large linear programs
A simplex-based method of solving specific classes of large-scale linear programs is presented. The structure of both staircase and block-angular linear programs is exploited to construct an advanced or "crash" basis to ...
Invariants of graphs
We address a classical problem in low dimensional topology: the classification of tamely embedded, finite, connected graphs $G$ in $S\sp3$ up to ambient isotopy. In the case that the graph $G$ is homeomorphic to $S\sp1$, ...
