    • Comparison of the CAF-DF and sage algorithms in multipath channel parameter estimation 

      Güldoğan, M. Burak; Arıkan, Orhan (IEEE, 2008-07)
      In this paper, performance of the recently proposed Cross Ambiguity Function - Direction Finding (CAF-DF) technique is compared with the Space Alternating Generalized Expectation Maximization (SAGE) technique. The CAF-DF, ...
    • Full-complex amplitude modulation with binary spatial light modulators 

      Ulusoy, E.; Onural, L.; Haldun M. Özaktaş (Optical Society of America, 2011-10-19)
      Imperfections and nonrobust behavior of practical multilevel spatial light modulators (SLMs) degrade the performance of many proposed full-complex amplitude modulation schemes. We consider the use of more robust binary ...
    • A multi-modal video analysis approach for car park fire detection 

      Verstockt, S.; Hoecke, S. V.; Beji, T.; Merci, B.; Gouverneur, B.; Cetin, A. E.; Potter, P. D.; Walle, R. V. D. (Elsevier, 2013)
      In this paper a novel multi-modal flame and smoke detector is proposed for the detection of fire in large open spaces such as car parks. The flame detector is based on the visual and amplitude image of a time-of-flight ...
    • Resonant harmonic response in tapping-mode atomic force microscopy 

      Sahin, O.; Quate, C. F.; Solgaard, O.; Atalar, Abdullah (American Physical Society, 2004)
      Higher harmonics in tapping-mode atomic force microscopy offers the potential for imaging and sensing material properties at the nanoscale. The signal level at a given harmonic of the fundamental mode can be enhanced if ...
    • Spatio-temporal evolution of ultrashort pulses in graded-index multimode fiber at normal dispersion 

      Teğin, Uğur; Ortaç, Bülend (IEEE, 2017)
      Summary form only given. A novel nonlinear phenomenon at normal dispersion regime inside of graded-index multimode fiber (GRIN MMF), geometric parametric instability (GPI), can be observed while propagating beam experiences ...
