    The set of ordinary differential equations (ODE) of a physical system determines the precise numerical behavior that will be exhibited in the future. Abstracting an ODE into a qualitative differential equation (QDE) system ...
  • Sivrikaya, Burak. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Movie production is a serious undertaking that requires a significant amount of investment. The success of a movie, i.e., positive return on investment, can only be realized with a good performance at the box-office well after ...
  • Erdem, Mustafa. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    This thesis presents work on previously developed hardware module for in-air ultrasound measurements and analysis. Redesigned hardware and firmware enable real-time ultrasound echo measurements which are then transmitted ...
  • Pala, İlkay Ramazan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2021., 2021.)
    The increasing difficulty of retrieving relevant information from rapidly growing literature has raised the interest for natural language processing (NLP) systems in the biomedical domain. In many of these systems, detection ...
  • Aydınoğlu, Şeyma Özkara. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    The overall purpose of this research study was to investigate new catalysts to produce synthesis gas via CO2 reforming of methane under optimized reaction conditions. The thesis consists of four parts. In the first part ...
  • Özgümüş, Beste. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Microalgae are known for their remarkable growth rates and adaptation capa bilities. In this study, microalgae were used as environmentally friendly materials for two different applications. The first part is focused on ...
  • Yıldız, Anıl. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2012., 2012.)

  • Beker, Haluk. (Thesis (Assoc. Prof.) - Bogazici University. Institute of Sciences and Engineering, 1977., 1977.)
  • Uzel, Kerem. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2014., 2014.)
    Sensory neuron in the olfactory system, typically expresses only a single olfactory receptor (OR) gene from a large and diverse genomic repertoire. In zebrafish, a violation of this ‘one neuron – one receptor rule’ has ...
  • 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 ...
  • 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. ...
  • Boyar, Onur. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
