    • Dynamic boundary control of the timoshenko beam 

      Morgül, Ö. (Pergamon Press, 1992)
      We consider a clamped-free Timoshenko beam. To stabilize the beam vibrations, we propose a dynamic boundary control law applied at the free end of the beam. We prove that with the proposed control law, the beam vibrations ...
    • Harmonic cantilevers for nanomechanical sensing of elastic properties 

      Sahin, O.; Yaralioglu, G.; Grow, R.; Zappe, S. F.; Atalar, Abdullah; Quate, C.; Solgaard, O. (Institute of Electrical and Electronics Engineers Inc., 2003)
      We present a micromachined scanning probe cantilever, in which a specific higher order flexural mode is designed to be resonant at an exact integer multiple of the fundamental resonance frequency. We have demonstrated that ...
    • Nanomechanics using an ultra-small amplitude AFM 

      Hoffmann P.M.; Jeffery, S.; Oral, Ahmet; Grimble, R.A.; Özer, Özgür H.; Pethica J.B. (2001)
      A new type of AFM is presented which allows for direct measurements of nanomechanical properties in ultra-high vacuum and liquid environments. The AFM is also capable to atomic-scale imaging of force gradients. This is ...
    • A new detection method for capacitive micromachine ultrasonic transducers 

      Ergun, A. S.; Temelkuran, B.; Ozbay, E.; Atalar, Abdullah (IEEE, 2001)
      Capacitive micromachine ultrasonic transducers (cMUT) have become an alternative to piezoelectric transducers in the past few years. They consist of many small circular membranes that are connected in parallel. In this ...
    • A new detection method for capacitive micromachined ultrasonic transducers 

      Ergun, A. S.; Temelkuran, B.; Özbay, E.; Atalar, Abdullah (IEEE, 1998)
      Capacitive micromachined ultrasonic transducers (cMUT) have become an alternative to piezoelectric transducers in the past few years. They usually consist of many small membranes all in parallel. In this work we report a ...
