    • Activity analysis for assistive systems 

      İşcen, Ahmet (Bilkent University, 2014)
      Although understanding and analyzing human actions is a popular research topic in computer vision, most of the research has focused on recognizing ”ordinary” actions, such as walking and jumping. Extending these methods ...
    • A bayesian network analysis of ethical behavior 

      Ekici, A.; Ekici, S. O. (SAGE Publications Inc., 2016)
      Using one of the major domains of macromarketing – ethics – this paper aims to introduce the Bayesian network (BN) method and demonstrate its added value for macro-level decision makers. Bayesian networks are particularly ...
    • Bistable behavior of a two-mode Bose-Einstein condensate in an optical cavity 

      Safaei, S.; Mustecaplioglu, Ö. E.; Tanatar, B. (IOP Institute of Physics Publishing, 2013-01-11)
      We consider a two-component Bose-Einstein condensate in a one-dimensional optical cavity. Specifically, the condensate atoms are taken to be in two degenerate modes due to their internal hyperfine spin degrees of freedom ...
    • Energy transfer rate in Coulomb coupled quantum wires 

      Tanatar, B. (American Institute of Physics, 1997)
      We study the energy transfer rate for electrons in two parallel quantum wires due to interwire Coulomb interactions. The energy transfer rate between the wires (similar to the Coulomb drag effect in which momentum transfer ...
    • Hydrodynamic type of integrable equations on a segment and a half line 

      Gurses, M.; Habibullin, I.; Zheltukhin, K. (American Institute of Physics, 2008)
      The concept of integrable boundary conditions is applied to hydrodynamic type systems. Examples of such boundary conditions for dispersionless Toda systems are obtained. The close relation of integrable boundary conditions ...
    • A new mapping heuristic based on mean field annealing 

      Bultan, T.; Aykanat, C. (Academic Press, 1992)
      A new mapping heuristic is developed, based on the recently proposed Mean Field Annealing (MFA) algorithm. An e cient implementation scheme, which decreases the complexity of the proposed algorithm by asymptotical factors, ...
    • Onion-Like (CdSe)ZnS/CdSe/ZnS quantum-dot-quantum-well heteronanocrystals for investigation of multi-color emission 

      Nizamoglu, S.; Demir, H. V. (Optical Society of America, 2008)
      We investigate multi-color spontaneous emission from quantum-dot-quantum-well heteronanocrystals made of onion-like (CdSe) ZnS/CdSe/ZnS ( core) shell/shell/shell structures, with our theoretical results explaining experimental ...
    • Optical implementations of two-dimensional fractional Fourier transforms and linear canonical transforms with arbitrary parameters 

      Sahin, A.; Ozaktas, H. M.; Mendlovic, D. (Optical Society of America, 1998-04-10)
      We provide a general treatment of optical two-dimensional fractional Fourier transforming systems. We not only allow the fractional Fourier transform orders to be specified independently for the two dimensions but also ...
    • Superimposed event detection by particle filters 

      Urfalioglu, O.; Kuruoglu, E. E.; Cetin, A. E. (The Institution of Engineering and Technology, 2011)
      In this study, the authors consider online detection and separation of superimposed events by applying particle filtering. They observe only a single-channel superimposed signal, which consists of a background signal and ...
