    • Computer vision based behavior analysis 

      Yücel, Zeynep (Bilkent University, 2009)
      In this thesis, recognition and understanding of behavior based on visual inputs and automated decision schemes are investigated. Behavior analysis is carried out on a wide scope ranging from animal behavior to human ...

    • Decentralized blocking zeros in the control of large scale systems

    • Exact and approximate decoupling and noninteracting control problems 

      Akar, Nail (Bilkent University, 1989)
      In this thesis, we consider “exact” and “approximate” versions of the disturbance decoupling problem and the noninteracting control problem for linear, time-invariant systems. In the exact versions of these problems, we ...

    • Fixed order controller design via parametric methods 

      Saadaoui, Karim (Bilkent University, 2003)
      In this thesis, the problem of parameterizing stabilizing fixed-order controllers for linear time-invariant single-input single-output systems is studied. Using a generalization of the Hermite-Biehler theorem, a new ...

    • Foraging motion of swarms as nash equilibria of differential games 

      Yıldız, Aykut (Bilkent University, 2016-09)
      The question of whether foraging swarms can form as a result of a non-cooperative game played by individuals is shown here to have an affirmative answer. A dynamic (or, differential) game played by N agents in one-dimensional ...

    • Stability of planar piecewise linear systems :a geometric approach 

      Abdullahi, Adamu (Bilkent University, 2015-09)
      This thesis focuses on the stability analysis of piecewise linear systems. Such systems consist of linear subsystems, each of which is active in a particular region of the state-space. Many practical and theoretical ...

    • Tracking and regulation control of a two-degree-of-freedom robot arm 

      Güler, Samet (Bilkent University, 2012)
      In this thesis, servomechanism synthesis for a two-degree-of-freedom (2-DOF) serial chain revolute-revolute joint robot arm that achieves internal stability, reference signal tracking, and torque disturbance regulation ...

    • A unification and comparison of the methods of construction for decentralized stabilizing controllers 

      Koçan, Ali Aydın (Bilkent University, 1993)
      In this thesis, the construction and characterization methods that use stable proper fractional representation for the solution of decentralized stabilization problem is presented in a unified manner. Four methods of ...

    • Vision based behavior recognition of laboratory animals for drug analysis and testing 

      Sandıkcı, Selçuk (Bilkent University, 2009)
      In pharmacological experiments, a popular method to discover the effects of psychotherapeutic drugs is to monitor behaviors of laboratory mice subjected to drugs by vision sensors. Such surveillance operations are currently ...

    • Watermarking via zero assigned filter banks 

      Yücel, Zeynep (Bilkent University, 2005)
      A watermarking scheme for audio and image files is proposed based on wavelet decomposition via zero assigned filter banks. Zero assigned filter banks are perfect reconstruction, conjugate quadrature mirror filter banks ...

    • A zero-assignment approach to two-channel filter banks and wavelets 

      Akbaş, Mustafa (Bilkent University, 2001)
      It is well-known that subband decomposition and perfect reconstruction of an arbitrary input signal is possible by a proper design of four lters. Besides having a wide range of applications in signal processing, perfect ...
