  • Hee Kho, Yau; Soon Chong, Nguan; Caglar Kizilirmak, Refik (IEEE Computer Society, 2016)
    This paper presents a design concept and implementation of an indoor passive tracking system that utilises an array of Wi-Fi transceivers, and without any electronic device or tag attached to the object being tracked. Such ...
  • Kupreyev, Dmitriy (Nazarbayev University School of Engineering and Digital Sciences, 2021-05)
    This thesis work presents design and modelling of highly efficient class E power am- plifier for broadband applications. Nearly 900 MHz bandwidth has been achieved with the center frequency at 2.0 GHz. The PAE was more ...
  • Ai-Khori, Jaber; Nauryzbayev, Galymzhan; Abdallah, Mohamed M.; Hamdi, Mounir (Institute of Electrical and Electronics Engineers, 2019-04)
    In this paper, we study physical layer security (PLS) aspects of a hybrid radio frequency (RF)/visible light communication (VLC) system with multiple decode-and-forward relaying nodes equipped with friendly jamming ...
  • Al-Khori, Jaber; Nauryzbayev, Galymzhan; Abdallah, Mohamed M.; Hamdi, Mounir (Institute of Electrical and Electronics Engineers, 2019-01-09)
    In this paper, we consider the secrecy of a hybrid radio frequency (RF)/visible light communication (VLC) system equipped with decode-and-forward relaying. We develop physical layer security algorithms that mitigate ...
  • Palumbo, Giovanna; Iadicicco, Agostino; Tosi, Daniele; Verze, Paolo; Carlomagno, Nicola; Tammaro, Vincenzo; Ippolito, Juliet; Campopiano, Stefania (Society of Photo-optical Instrumentation Engineers (SPIE), 2016-11)
    We report on the integration of fiber optic sensors with commercial medical instrumentation for temperature monitoring during radio frequency ablation for tumor treatment. A suitable configuration with five fiber Bragg ...
