    Aksen, Ahmet; Yarman, Bekir Sıddık Binboğa (IEEE, 2003)
    This paper addreses the use of mixed lumped and distributed elements in the matching equalizers of broadband microwave communication subsytems in MMIC realizations. Construction of two-variable scattering functions for ...
  • Particle dynamics in the KdV approximation 

    Borluk, Handan; Kalisch, Henrik (ELSEVIER SCIENCE BV, 2012-12)
    The KdV equation arises in the framework of the Boussinesq scaling as a model equation for waves at the surface of an inviscid fluid. Encoded in the KdV model are relations that may be used to reconstruct the velocity field ...
  • Partner selection and resource allocation in single-cell, multi-cell and cognitive cooperative multiple access channels 

    Bakşi, Saygın (Işık Üniversitesi, 2013-06-06)
    Wireless communication has been widely used across the globe for several years. As the technology advances and gains popularity, more people start using it and more throughput is needed. For that reason, several techniques ...
  • Passion of chaotic cryptography 

    Solak, Ercan (IEEE, 2013)
    Despite being an active research area for the last two decades, chaotic cryptography has not found a place in mainstream cryptography literature. This paper explores the reasons for this separation.

  • Perceived self-society moral discrepancies predict depression but not anxiety 

    Peker, Müjde; Gündoğdu, Nurdan; Booth, Robert W. (Blackwell Publishing Ltd, 2015-12)
    Discrepancies between one's own beliefs, standards and practices and the standards expected by others are associated with increased vulnerability to depression and anxiety. Perhaps the most important personal standard is ...
  • Perception of it governance in Turkey 

    Ermiş, Fatih (Işık Üniversitesi, 2012)
    Effective governance of IT in an organization is essential for delivering value to its business. IT Governance can be identified as an integral part of enterprise governance that includes processes and methods for making ...
