    Delayed Feedback Control (DFC) method proposed by Pyragas is a simple and efficient method to control chaotic systems by stabilizing the Unstable Periodic Orbits (UPOs) of these systems. Assuming that a UPO with period T ...
  • Yapar, Ufuk. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    Most sigma delta modulators are realized in the discrete-time domain using circuit techniques such as switched capacitor. In typical discrete time implementations, there are some speed constraints. For example, maximum ...
  • Uzun, Orçun. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Streams ciphers are appropriate for high speed encrypted communications because this type of ciphers provide high output speed and ease of implementation in hardware. Generally, stream ciphers makes use of Linear Feedback ...
  • Haznedaroğlu, Ali. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In large vocabulary continuous speech recognition based keyword spotting applications, language modeling directly affects the system performance. In this study, a keyword adapted language model is proposed and a Turkish ...
  • Seren, Ümit. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    Compression of sequence is one of the most useful tools for strengthening the pseudo-random generators used in stream ciphers. Using compression components can prevent algebraic attacks against LFSR-based stream ciphers. ...
  • Demirelli, Atanur. (Thesis (M.S.) - Robert College. Faculty of Graduate School of Engineering, 1969., 1969.)
    A survey of infrared principles is given in an attempt to determine the factors effecting the performance of infrared detection system. Various detection phenomena are discussed in a comparative manner. A full treatment ...
  • Özgan, Meltem Doğaner. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    In cryptographic systems, usually linear feedback shift register based keystream generators are used because of the fact that they can produce sequences with large period, good statistical properties. They are suitable for ...
  • Yılmaz, Ender. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
