  • Aktan, Mustafa. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    Digital filters are the most frequently used elements in signal processing applications. Among digital filters, FIR filters are preferred due to their stability, easily achievable linear-phase property, and low quantization ...
  • Akgül, Ceyhun Burak. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    Next generation search engines will enable query formulations, other than text, relying on visual information encoded in terms of images and shapes. Content-based retrieval research aims at developing search engines that ...
  • Apaydın, Gökhan. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    This thesis presents fundamental overview of electromagnetics and finite element method (FEM) with weighted extended basis splines (web-splines), which is a new developed finite element method for electromagnetic problems. ...
  • Gençağa, Orhan Deniz. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    This thesis brings a unifying approach for modeling non-stationary non-Gaussian signals which are widely encountered in many multidisciplinary research fields. In the literature, different approaches have been used to model ...
  • Metin, Bilgin. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In the beginning years of the analog design, discrete components were being used in the analog design procedures. After manufacturing, trimmer capacitors and potentiometers were used for electronic tunability to compensate ...
  • Cezayirli, Ahmet. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    Adaptive control of nonlinear systems is considered in this study. Available methods in this field are reviewed first. Focusing on the minimum-phase, input-output linearizable and linearly parameterized nonlinear systems, ...
  • Türk, Oytun. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    Cross-lingual voice conversion refers to the automatic transformation of a source speaker’s voice to a target speaker’s voice in a language that the target speaker can not speak. It involves a set of statistical analysis, ...
  • Yüce, Erkan. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Current conveyor (CC) is one of the most widely used versatile active components. It potentially provides higher accuracy, wider bandwidth, greater linearity and larger dynamic range. The advantages of the CCs have brought ...
  • Doğan, Mustafa. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Developing nonlinear adaptive and robust controllers for a two-link flexible robot arm is the main objective of this research. Two different modelling techniques are used to overcome model accuracy problems and these two ...
  • Efe, Mehmet Önder. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2000., 2000.)
    Noise rejection, handling the plant-model mismatches and alleviation of structured or unstructured uncertainties constitute prime challenges that are frequently encountered in the practice of systems and control engineering. ...
  • Demirci, Ufuk. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2004., 2004.)
    The challenging control problem of underwater vehicles is addressed in this study under excessive sea wave disturbances at shallow submerged operation. The systems are becoming more and more complex with the effect of rapid ...
  • Yaz, Engin. (Thesis (Ph.D)- Bogazici University. Institute for Graduate Studies in Science and Engineering, 1982., 1982.)
    In this thesis, the deterministic, stochastic and stochastic adaptive coritrolpossibilities based on the method of receding horizon is examiried. The receding horizon method assumes a fixed horizon length for feedback law ...
