A passive wireless tracking system for indoor assistive monitoring

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 ...
Joint Beamforming Design and Power Minimization for Friendly Jamming Relaying Hybrid RF/VLC Systems

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 ...
Secrecy Performance of Decode-and-Forward Based Hybrid RF/VLC Relaying Systems

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 ...
Temperature profile of ex-vivo organs during radio frequency thermal ablation by fiber Bragg gratings

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 ...
