  • Texture Analysis Based Iris Recognition 

    Gürkan, Güray; Akan, Aydın (2006-01)
    In this paper, we present a new method for personal identification, based on iris patterns. The method composed of iris image acquisition, image preprocessing, feature extraction and finally decision stages. Normalized ...
  • A novel EOG-based wireless rapid communication device for people with motor neuron diseases 

    Uşaklı, Ali Bülent; Gürkan, Serkan; Gürkan, Güray (Taylor and Francis Online, 2018-11-22)
    In this study, a new electrooculography (EOG) based system that provides efficient communication for people suffered from motor neuron diseases is presented. The system consists of two distinct devices. The first device ...
  • Adaptive dual-mode OFDM with index modulation 

    Aldırmaz Çolak, Sultan; Acar, Yusuf; Başar, Ertuğrul (Elsevier Science Bv, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2018-10)
    With the integration of the index modulation concept, the popular OFDM has gained an appealing new dimension. However, OFDM with index modulation (OFDM-IM) causes a decrease in data rate for higher order modulations due ...
  • Fuzzy logic based control of switched reluctance motor to reduce torque ripple 

    Derdiyok, A.; İnanç, N.; Özbulur, Veysel; Pastacı, Halit; Bilgiç, Mehmet Oruç (IEEE, 1997)
    This paper presents torque ripple reduction of a switched reluctance motor (SRM) by using a fuzzy speed controller. For this purpose, current control is applied with a fuzzy speed controller. The fuzzy controller adjusts ...
  • Improving performance of switched reluctance motor by fuzzy logic controller 

    Derdiyok, A.; Inanc, N.; Özbulur, Veysel; Bilgiç, Mehmet Oruç (1999-04)
    This paper presents torque ripple minimization of a switched reluctance motor (SRM) by using a fuzzy controller, The nonlinear model of the SRM and the mathematical model of the converter circuit are driven. The motor used ...
  • Power converters as natural gyrators 

    Ehsani, Mehrdad; Husain, Iqbal; Bilgiç, Mehmet Oruç (IEEE, 1993-12)
    The authors investigate the open-loop gyrator behavior of a class of DC-DC converters that are characterized by double bridges. If the switching frequency of the double bridge converter is high enough with respect to its ...
  • Inverse dual converter (IDC) for high power DC-DC applications 

    Ehsani, M.; Husain, I.; Bilgiç, Mehmet Oruç (IEEE, April 1993)
    A family of DC-DC converters suitable for high-power applications is introduced. The inverse dual converter (IDC) is capable of continuous voltage step-up or step-down control over a wide range of and without the need of ...
  • Magnetically inflatable SPS with energy storage capability 

    Ehsani, M.; Bilgiç, Mehmet Oruç; Patton, A. D.; Mitra, J. (IEEE, 1995)
    A new approach to superconductive magnetic energy storage (SMES) for solar power satellite (SPS) with inherent rigidity is introduced in this paper. The rigidity of this SMES originating from the electromagnetic forces ...
  • Capacitor coupled converter (C3) for high power DC conversion 

    Ehsani, Morteza; Bilgiç, Mehmet Oruç; Khan, S.; Laskai, L.; Jeong, Seung-Gi (IEEE, 1995)
    The bang-bang controlled capacitor coupled converter (C<sup>3</sup>) is described in this paper. Due to the converter's inherent commutating property, the C<sup>3</sup> can accommodate thyristors as well as high-power gate ...
  • New architectures for space power systems 

    Ehsani, M.; Bilgiç, Mehmet Oruç; Patton, Alton D.; Mitra, J. (IEEE, 1995-08)
    Electric power generation and conditioning have experienced revolutionary development over the past two decades. Furthermore, new materials such as high energy magnets and high temperature superconductors are either available ...
