    System-on-a-chip solutions require hardware based integrated circuit (IC) random number generator (RNG) for trustworthy transmission of information. Fully digital gate based IC RNGs became popular because of their uncomplicated ...
  • Demir, Cemil. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    In this dissertation, we analyze the single-channel speech-music separation problem for automatic speech recognition (ASR). The motivation of the study is to increase the performance of the ASR systems by decreasing the ...
  • Aras, Ayşe Çisel. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    In this study, a novel approach is described to the design of an interval type- 2 fuzzy neural system (IT2 FNS). It differs from the classical IT2 FNS in its use of parameterized conjunctors. In the optimization of the IT2 ...
  • Erdim, Füsun. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1985., 1985.)
    Effective spreading of the use of muLtiprocessors, -or distributed processing in general-, and achieving the potential advantages of this new design option require various hardware and software-related probLems to be solved. ...
  • Öniz, Yeşim. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    The main shortcomings with the gradient descent-based learning algorithms used for neural networks are that the convergence speed is relatively slow and the algorithm can be easily trapped into a local optimum. The studies ...
  • Çitkaya, Ahmet Yasin. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    The assessment of exposure level due to commonly used light sources needs specific attention in today's technology of lighting. The main reason behind this concern is that if exposure levels are not known, the biological ...
  • Cihan, Onur. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    The problem of achieving a common value in a distributed information sharing context, referred to as distributed consensus or agreement, is an important topic that has drawn significant research attention of late. Consensus ...
  • Bayram, Haluk. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    This thesis is concerned with multi-robot systems. Robots are increasingly being used in applications such as patrolling or exploration whose natures necessitate the consideration of multiple cooperating robots. The ...
  • Sarıoğlu, Baykal. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    The use of minimally invasive medical techniques has greatly reduced risks to patients and has increased our understanding of how the body works. Detection of catheters is one of the most important tasks in these techniques. ...
  • Erkent, Özgür. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
