    In this thesis, design and characterization of a new atomic force microscopy (AFM) setup having conventional piezoactuator together with an electromagnetic actuator and a novel AFM technique using miniaturized-magnetic ...
  • Özyar, Ahmet Onur. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    In this study, a novel self-tuning passive lever-type vibration isolation system for base excitations is described. Due to inertial coupling within the vibration isolation system, an antiresonance frequency is generated, ...
  • Özdemir, Ömer Faruk. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    Technological developments made in the near past, gave us a chance to analyze respiratory sounds quantitatively. Digitization of respiratory sounds, obviously, was the key in the analysis of respiratory sounds. Although ...
  • Arslan, Salim Melih. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2011., 2011.)
    As the security and privacy awareness continuously arise, cryptographic services such as data con dentiality, integrity, authentication, and non-repudiation become an essential and indispensable part of digital systems and ...
  • Karasaban, Mahmut Şevket. (Thesis (M.A)-- Engineering School of Robert College, İstanbul-Turkey, 1936., 1936.)
  • Altunbaş, Adlen. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2012., 2012.)
    The determination of geostatic stresses has a significant role on the analysis and design of various geotechnical structures, including retaining walls, piles and underground structures. Therefore correct estimation of the ...
  • Bektaş, Kemal. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    This thesis is concerned with the design and development of a social robot that can navigate around in a socially compliant manner. The importance of this problem is due to the growing demand of using robots in human-populated ...
  • Kömürcü, Erman. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Auscultation is a common method among physicians to detect adventitious sounds which are mainly wheezes and crackles, and are important indicators of a pathological condition. According to the presence of these adventitious ...
  • Sancı, Selim. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Drag is a big problem for objects moving at high speeds. The reduction of dragshould be the primary consideration of the engineers since it provides high speeds withlimited engine power. Drag reduction also provides energy ...
  • Atakuru, Taylan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2017., 2017.)
    Parallel manipulators are closed-loop mechanisms presenting superior performance compared to serial manipulators in terms of speed, accuracy, precision, and rigidity. They have become widely popular in the industry in the ...
  • Demircioğlu, Hüseyin. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2018., 2018.)
    In this thesis, two tasks for quadrotors are presented. The first is an inner and the second is an outer loop control design for quadrotors. For the first task, an adaptive contoller for quadrotors is designed. During the ...
  • Acar, Mustafa Ali. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2011., 2011.)
    In this study, a new adaptive-passive dynamic vibration absorber design is discussed. This proposed design is composed of a stiff string under tension with a central mass attachment as a dynamic vibration absorber (DVA), ...
