    • Diffusive MASS NMR Studies of Transport in Porous Materials 

      Liu, Yun; Leu, Gabriela; Cory, David G.; Sen, Pabitra (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
      NMR methods are widely used to probe the structure and fluid dynamics of porous materials including such diverse materials as cheese and chocolate, cosmetics and pharmaceuticals, solvents in resins and soft matter, biological ...
    • Subsurface Imaging with Reverse Vertical Seismic Pro les 

      Krasovec, Mary L.; Coates, Richard; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
      A novel imaging process, referred to as vector image isochron (VII) migration, is specifically designed to reduce artifacts caused by arrays with limited apertures. By examining the assumptions behind generalized Radon ...
    • Wavelet domain linear inversion with application to well logging 

      Kane, Jonathan; Herrmann, Felix; Toksoz, M. Nafi (Massachusetts Institute of Technology. Earth Resources Laboratory, 2001)
      Solving linear inversion problems in geophysics is a major challenge when dealing with non-stationary data. Certain non-stationary data sets can be shown to lie in Besov function spaces and are characterized by their ...
