Adaptation and migration of a population between patches
Structured populations phenotypical and spatial structure Hamilton-Jacobi equation viscosity solutions Dirac concentrations stationary solutions
2012/4/23
A Hamilton-Jacobi formulation has been established previously for phenotypical structured population models where the solution concentrates as Dirac masses in the limit of small diffusion. Is it possi...

Linearized inverse seismic Reverse Time Migration
2011/2/23
In this paper we study the linearized inverse problem associated with imaging of re ection seismic data.
In this paper we present a simple database definition language:that of categories and functors. A database schema is a category and a state is a set-valued functor. We show that morphisms of schemas i...
3D HYBRID DEPTH MIGRATION AND FOUR-WAY SPLITTING SCHEMES
3D depth migration Multiway splitting Data line Wavefield computation Finite-difference Hybrid method
2007/12/12
The alternately directional implicit (ADI) scheme is usually
used in 3D depth migration. It
splits the 3D square-root operator along crossline and inline
directions alternately.
In this paper, bas...
