  • A comparison of fuzzy methods for modeling 
    Aras, Ayşe Çisel. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    Type-1 Fuzzy Logic Controllers (FLCs) have been used in control applications for more than thirty years. However, traditional type-1 FLCs are de cient in dynamical unstructured environments and in many real-time applications ...
  • Adaptive fuzzy sliding mode control of a washing machine oscillating system 
    Tamyaman, Can. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2005., 2005.)
    To prevent any mechanical damage, washing machines distribute the load (the laundry)before performing any spins. After some distributive motor movements, there may still besome load that does not lay homogenously on the ...
  • Control of inverted pendulum:| comparison of various strategies for swing up and balancing 
    Er, Fatih. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2005., 2005.)
    In this thesis, two different control schemes are designed for swinging up and three different schemes for balancing of an inverted pendulum, a non-linear electro-mechanical system with open loop unstablity. The controllers ...
  • Fusion of soft computing techniques in control applications 
    Koku, A. Buğra. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Sciences and Engineering, 1997., 1997.)
    The main objective of this thesis work is the formation of an experimental garden, suitable for the demonstration of classical and advanced control concepts, by , an integration of the computational ca.pabilities and the ...
  • Grey prediction based control of a non-linear liquid level system using PID type fuzzy controller 
    Kayacan, Erdal. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    This thesis proposes a grey system theory based fuzzy PID controller that has a prediction capability. Although fuzzy control theory and grey system theory have completely different mathematical basics, both deal with ...
  • Interval type-2 fuzzy logic systems: theory and design 
    Kayacan, Erdal. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2011., 2011.)
    This Ph.D. dissertation has four main objectives. Firstly, the noise reduction property of type-2 fuzzy logic systems that use a novel type-2 fuzzy membership function is studied. A number of papers exist in literature ...
  • Modelling stock market via fuzzy rule based systems 
    Aksoy, Hakan. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Social Sciences, 2004., 2004.)
    A rule based fuzzy logic model is implemented to forecast the monthly return of the Istanbul Securities Exchange 100 (ISE100) Index by combining common stock market data analysis techniques. These are technical analysis, ...
  • Software selection for a liner shipping company using fuzzy logic decision making 
    Akpınar, Eşref. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2005., 2005.)
    This thesis mainly focuses on selection of software for managing operations ofEMES Shipping and Transportation Company by the evaluations of scripted scenarios,requests for information (RFI), and demonstrations from software ...
  • The complexity of debate checking 
    Demirci, Hüseyin Gökalp. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    We introduce a model of probabilistic debate checking, where a silent resourcebounded veri er reads a dialogue about the membership of a given string in the language under consideration between a prover and a refuter. Our ...
  • TYPE-4 fuzzy clustering for fuzzy modeling applications 
    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 ...
  • Variable structure systems based online learning algorithms for type-1 and type-2 fuzzy neural networks 
    Çiğdem, Özkan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2011., 2011.)
    Type-2 fuzzy logic systems are proposed in the literature as an alternative to type-1 fuzzy logic systems because of their abilities to more e ectively model rule uncertainties. This thesis extends the idea of using the ...
