  • Active noise control in a duct with flow 
    Yüksel, Osman. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2012., 2012.)
    In this thesis, active noise control in a duct with ow is investigated. A one dimensional acoustic duct model, in which uid medium inside the duct has a mean ow velocity, is presented. The acoustic duct model is solved ...
  • Autotunning and robustness of multi-loop pid-controlled mulltivariable processes 
    Deva, Ergin Levent. (Thesis (M.S.)- Bogazici University. Institute for Graduate Studies in Science and Engineering, 2000., 2000.)
    In this study, decentralized PID controllers which are commonly used in process industry are applied to multi-input multi-output systems. A short literature survey is done and basic characteristics of these systems with ...
  • Boundary control of transient temperature in internal pipe flow heat transfer by POD-Galerkin ROM 
    Eren, Erdem. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    The aim of this thesis is to investigate the model reduction and modern control methods used in study of fluid stability and control. Some of the modern methods of reduced order modeling and control are applied to a ...
  • Closed-loop actuator and sensor location selection strategies for flexible structures 
    Güney, Murat. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    In this thesis, the problem of finding the optimal actuator and sensor locations for vibration control of a flexible structure is studied. An iterative search strategy is used, where the closedloop criteria are selected ...
  • Combined longitudinal-torsional vibration of sandwiched piezoelectric ultrasonic transducers 
    Demir, Bülent Güven. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In this thesis, combined longitudinal-torsional vibration of ultrasonic transducer using impedance matching method is studied. In combined vibration, two modes must resonate in the same frequency. Impedance matching method ...
  • Control and optimization of cure cycle for thick-sectioned thermoset composites manufacturing 
    Ünlühisarcıklı, Özer. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    The objective of this study was to minimize the temperature gradients encountered in thick-sectioned thermoset composites manufacturing. For this purpose, a finite difference analysis based on mathematical models representing ...
  • Control of an obstacle avoider mobile robot using image processing 
    Kulgu, Turgay. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    This study investigates control of a mobile Lego robot moves towards to the specified target without hitting the obstacles with the help of image processing. An experimental set-up was designed and conducted for experiments. ...
  • LPV control of two link flexible manipulator 
    Polat, İlhan. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    This thesis is concerned with the design of controllers for Linear Parameter Varying (LPV) systems in nonsingular descriptor form using a parameter dependent Lyapunov function. The systems considered are in the form of ...
  • Optimum vibration absorbers for continuous and discrete mechanical systems 
    Tursun, Murat. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    In this thesis, the optimum parameters of passive vibration absorbers for continuous and discrete mechanical systems are investigated. Two approaches are undertaken to obtain the optimum absorber parameters. The first ...
  • Physical based analysis and model reduction of engineering systems 
    Orbak, Ali Yurdun. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2003., 2003.)
    There is a need for obtaining low order approximations of high order models of physical systems as low order models result in several advantages including the reduction of computational complexity and improved understanding ...
