    • Simultaneous least squares deconvolution and kriging using conjugate gradients 

      Kane, Jonathan; Rodi, William; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
      Least squares deconvolution is a method used to sharpen tomographic images of the earth by undoing the bandlimiting effects imposed by a seismic wavelet. Kriging is a method used by geoscientists to extrapolate and interpolate ...

    • The effect of stresses on the sound velocity in rocks: Theory of Acoustoelasticity and Experimental Measurements 

      Huang, Xiaojun; Burns, Daniel R.; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
      The theory of acoustoelasticity provides direct link between the change of elastic wave velocities and residual stresses in solids. The general theory of acoustoelasticity is reviewed. A number of experimental measurements ...

    • Determination of Near-Surface Anisotropy From Surface Electromagnetic Data 

      Al-Dajani, AbdulFattah; Morgan, Frank Dale; Toksoz, M. Nafi; Repperty, Philip (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
      Ground penetrating radar (GPR) signatures, such as reflection moveout, are sensitive to the presence of azimuthal anisotropy. Azimuthal anisotropy can occur as an intrinsic property of the medium and/or due to the presence ...
