• Computationally Efficient Methods for Seismic Modeling and Inversion 

      Sarajærvi, Martin (Doctoral thesis, 2020-11-18)
      This thesis presents new methods for the modeling of seismic waveforms based on ray theory and ray-Born integrals. The waveforms are used in forward modeling, imaging and full waveform inversion and are computed in 3D ...
    • Inversion of the Linear and Parabolic Radon Transform 

      Sarajærvi, Martin (Master thesis, 2010-05-31)
      Different mathematical techniques are applied to the linear and parabolic Radon transforms. Including a review of classical work, recent developments, and testing of two proposed methods. Studies span from sampling and ...
