    • Finite size effects in cooperative molecular motors 

      Taneri, S.; Yalabik, M. C. (Elsevier B.V., 2003)
      We have studied the ballistic and damped dynamics of finite size cooperative molecular motors. We study the effect of finite size on average quantities such as sliding velocity, as well as the statistics of fluctuations ...
    • Incorporating doppler velocity measurement for track initiation and maintenance 

      Kural F.; Arikan F.; Arikan, O.; Efe, M. (2006)
      Performance of multiple target tracking algorithms in complex environments heavily relies on the success of track initiation and measurement-to-track association algorithms. Doppler velocity measurement is the major ...
    • Interpolation techniques to improve the accuracy of the plane wave excitations in the finite difference time domain method 

      Oğuz, U.; Gürel, L. (Wiley-Blackwell Publishing, Inc., 1997-11)
      The importance of matching the phase velocity of the incident plane wave to the numerical phase velocity imposed by the numerical dispersion of the three-dimensional (3-D) finite difference time domain (FDTD) grid is ...
    • Investigation of AlGaN buffer layers on sapphire grown by MOVPE 

      Van Gemmern P.; Dikme, Y.; Biyikli, N.; Kalisch H.; Özbay, E.; Jansen, R.H.; Heuken, M. (2004)
      In this work, AlGaN layers were grown on sapphire by metal-organic vapor phase epitaxy (MOVPE) on (0001)-oriented sapphire substrates, with the intention to investigate the effect of varying Al/MO and V/III ratios on the ...
    • Magnetic and electric Aharonov-Bohm effects in nanostructures 

      Kulik, I. O. (Elsevier BV, 1996)
      The paper reviews and extends the magnetic Aharonov-Bohm effect (persistent current, resistance oscillation) in normal-metal rings including spin-independent and spin-dependent hopping, Zeeman splitting, magnetic textures ...
    • A novel equivalent circuit model for CMUTs 

      Oguz H.K.; Olcum, S.; Senlik, M.N.; Atalar, Abdullah; Köymen H. (2009)
      A nonlinear equivalent circuit for immersed transmitting capacitive micromachined ultrasonic transducers (CMUTs) is presented. The velocity profile across the CMUT surface maintains the same form over a wide frequency ...
    • On the stabilization of a cable with a tip mass 

      Morgül, Ö.; Rao, B. P.; Conrad, F. (IEEE, 1994)
      In this note, we consider a vertical cable which is pinched at the upper end. A mass is attached at the lower end where a control force is also applied. We show that this hybrid system is uniformly stabilized by choosing ...
    • Performance evaluation of track association and maintenance for a MFPAR with doppler velocity measurements 

      Kural, F.; Arikan, F.; Arikan, O.; Efe, M. (2010)
      This study investigates the effects of incorporating Doppler velocity measurements directly into track association and maintenance parts for single and multiple target tracking unit in a multi function phased array radar ...
    • Radiation properties of sources inside photonic crystals 

      Bulu, I.; Caglayan, H.; Ozbay, E. (2003)
      In this work, we have experimentally studied the emission of radiation from a monopole source embedded in a photonic crystal. We have demonstrated the enhancement of radiation at the band edges and at the cavity modes ...
    • Rapid classification of surface reflectance from image velocities 

      Doerschner, K.; Kersten, D.; Schrater P. (2009)
      We propose a method for rapidly classifying surface reflectance directly from the output of spatio-temporal filters applied to an image sequence of rotating objects. Using image data from only a single frame, we compute ...
    • Temperature dependence of the energy of a vortex in a two-dimensional Bose gas 

      Rajagopal, K. K.; Tanatar, B.; Vignolo, P.; Tosi, M. P. (Elsevier, 2004)
      We evaluate the thermodynamic critical angular velocity Ωc(T) for creation of a vortex of lowest quantized angular momentum in a strictly two-dimensional Bose gas at temperature T, using a mean-field two-fluid model for ...
