    King, Hunter. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    Cellular automata (CA) are often used to model traffic flow with the intent to both better understand the internal dynamics of traffic from a statistical physics point of view, and to create virtual experiments which cannot ...
  • Chameleon search in Cast experiment at CERN 
    Bayirli, Arif. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2017., 2017.)
    Chameleons are hypothetical particles that are proposed as a scalar field to ac count for the accelerated expansion of the universe, the so-called ‘dark energy problem’. They are proposed to be produced in the high magnetic ...
