  • Design of a video laryngeal stroboscopy system for studying vocal fold pathology 
    Işık, Gökhan. (Thesis (M.S.)-Bogazici University. Institute of Biomedicail Engineering, 2004., 2004.)
    Video Laryngeal Stroboscopy (VLS) is a stroboscopic imaging technique that allows observations of standstill and slow motion images of vibrating vocal folds. It is a valuable tool for studying vocal fold pathology, for ...
  • Dielectrophoretic force stimulation for bone francture healing 
    Kibritoğlu, Erman. (Thesis (M.S.) - Bogazici University. Institute of Biomedical Engineering, 2013., 2013.)
    On the average, a person has two bone fractures during a lifetime. The healing time depends on the age, the health of the patient, the type and the severity of the fracture and can be quite long, especially if there is an ...
  • Effects of early and delayed laser application on nerve regeneration 
    Akgül, Tüba. (Thesis (M.S.) - Bogazici University. Institute of Biomedical Engineering, 2012., 2012.)
