  • A fast local level set method for inverse gravimetry 

    Isakov, Victor, 1947-; Leung, Shingyu; Qian, Jianliang (Global-Science Press, 2011)
    We propose a fast local level set method for the inverse problem of gravimetry. The theoretical foundation for our approach is based on the following uniqueness result: if an open set D is star-shaped or x(3)-convex with ...
  • A three-dimensional inverse gravimetry problem for ice with snow caps 

    Isakov, Victor, 1947-; Leung, Shingyu; Qian, Jianliang (American Institute of Mathematical Sciences, 2013-05)
    We propose a model for the gravitational field of a floating iceberg D with snow on its top. The inverse problem of interest in geophysics is to find D and snow thickness g on its known (visible) top from remote measurements ...
