      Balantekin, M.; Atalar, Abdullah (American Physical Society, 2005-03)
      In a tapping-mode atomic force microscope, the frequency spectrum of the oscillating cantilever contains higher harmonics at integer multiples of the excitation frequency. When the cantilever oscillates at its fundamental ...

    • Frequency response analysis and reconstruction weighting schemes for MR elastography 

      Arıyürek, Cemre (Bilkent University, 2020-09)
      Magnetic resonance elastography (MRE) non-invasively and quantitatively assesses the elasticity of the in-vivo tissue. In MRE, shear waves are induced to the tissue by an actuator, while phase-contrast images are obtained ...
