    • Comparison of terahertz technologies for detection and identification of explosives 

      Beigang, R.; Biedron, S. G.; Dyjak, S.; Ellrich, F.; Haakestad, M.W.; Hübsch, D.; Kartaloglu, Tolga; Özbay, Ekmel; Ospald, F.; Palka, N.; Puc, U.; Czerwiñska, E.; Sahin, A. B.; Sešek, A.; Trontelj, J.; Švigelj, A.; Altan, H.; Van Rheenen, A.D.; Walczakowski, M. (SPIE, 2014-05)
      We present results on the comparison of different THz technologies for the detection and identification of a variety of explosives from our laboratory tests that were carried out in the framework of NATO SET-193 THz ...
    • Cumulant based identification approaches for nonminimum phase FIR systems 

      Alshebeili, S. A.; Venetsanopoulos, A. N.; Çetin, A. Enis (IEEE, 1993)
      In this paper, recursive and least squares methods for identification of nonminimum phase linear time-invariant (NMP-LTI) FIR systems are developed. The methods utilize the second- and third-order cumulants of the output ...
    • Econometric tests of asset price bubbles: taking stock 

      Gürkaynak, R. S. (Wiley-Blackwell Publishing Ltd., 2008)
      Can asset price bubbles be detected? This survey of econometric tests of asset price bubbles shows that, despite recent advances, econometric detection of asset price bubbles cannot be achieved with a satisfactory degree ...
    • The effect of context-dependent lightness on contrast detection and identification, and its neural correlates 

      Karatok, Zahide Pamir (Bilkent University, 2017-11)
      Perceived contrast of a grating varies with its background (or mean) luminance: of the two gratings with the same photometric contrast the one on higher luminance background appears to have higher contrast. On the other ...
    • Neural network-based modelling of subsonic cavity flows 

      Efe, M. Ö.; Debiasi, M.; Yan, P.; Özbay, Hitay; Samimy, M. (Taylor & Francis, 2008)
      A fundamental problem in the applications involved with aerodynamic flows is the difficulty in finding a suitable dynamical model containing the most significant information pertaining to the physical system. Especially ...
