  • de Andrés, Ana I.; O'Keeffe, Sinéad; Chen, Lingxia; Esteban, Óscar (IEEE Computer Society, 2017)
    An extrinsic X-ray fiber sensor with improved sensitivity is presented. The developed device is based on an inorganic scintillator (Terbium doped Gadolinium Oxysulfide) attached to a polymer fiber tip. Sensitivity ...
  • Kam, Wern; Mohammed, Waleed Soliman; Leen, Gabriel; O'Keeffe, Mary; O'Sullivan, Kieran; O'Keeffe, Sinéad; Lewis, Elfed (IEEE Computer Society, 2017)
    In this paper, a plastic optical fiber sensor for respiratory monitoring purposes is presented. The sensor was integrated into a small, robust, and flexible package to be attached directly on a wide variety of positions ...
  • Ji, Zhanlin; Ganchev, Ivan; O’Droma, Máirtín (Hindawi Publishing Corporation, 2010)
    The wireless billboard channels (WBCs) are integral part of the ubiquitous consumer wireless world (UCWW)—a wireless next generation network proposal. The WBCs are used by the service providers to broadcast advertisements ...
  • Ji, Zhanlin; Ganchev, Ivan; O’Droma, Máirtín (Hindawi Publishing Corporation, 2010)
    This paper presents two novel smart cross-layer error-control coding schemes for improving the error protection of service advertisements that are broadcast to mobile terminals on wireless billboard channels (WBCs) established ...
  • Jiang, Yuxuan; Fang, Zaijin; Du, Yanqiu; Lewis, Elfed; Farrell, Gerald; Wang, Pengfei (Optical Society of America, 2018)
    A novel temperature sensor based on a Teflon capillary encapsulated 2 × 2 optical microfiber coupler (OMC) filled with refractive index matching liquids is described. The sealed capillary and the filling liquid are ...
  • Talpur, Anum; Shaikh, Faisal K.; Newe, Thomas; Sheikh, Adil A.; Felemban, Emad; Khelil, Abdelmajid (SAGE, 2017)
    In the Internet of things, a large number of objects can be embedded over a region of interest where almost every device is connected to the Internet. This work scrutinizes the broadcast overhead problem in an Internet of ...
  • Docker, Peter; Morris, Robert; Newton, Michael; Dye, Elizabeth; Kay, James; Beale, John; Axford, Danny; Orville, Allen; Stuart, Dave; Leen, Gabriel (IFSA Publishing, S.L., 2017)
    The system described in this work is a variant from traditional acoustic levitation first described by, Marzo et al [1]. It uses multiple transducers eliminating the requirement for a mirror surface, allowing for an open ...
  • Heffernan, Donal; MacNamee, Ciaran (Elsevier, 2016)
    This paper exploits the observability of control messages in a control network to formally monitor safety properties to verify a control application's correct behaviour. A monitor scheme is proposed based on a runtime ...
  • Tian, Ke; Farrell, Gerald; Wang, Xianfan; Yang, Wenlei; Xin, Yifan; Liang, Haidong; Lewis, Elfed; Wagn, Pengfei (Optical Society of America, 2017)
    A fibre-optic strain sensor based on a gourd-shaped joint multimode fibre (MMF) sandwiched between two single-mode fibres (SMFs) is described both theoretically and experimentally. The cladding layers of the two MMFs are ...
  • Hu, Yaosheng; Qin, Zhuang; Ma, Yu; Zhao, Wenhui; Sun, Weimin; Zhang, Daxin; Chen, Ziyin; Wang, Boran; Tian, He; Lewis, Elfed (Elsevier, 2018)
    In-vivo real-time dose rate measurement has attracted much attention in the tumour-treatment field because of the demand for precise delivery of radiotherapy. An optical fiber based dosimeter is presented, which is fabricated ...

    In order to meet the increasing demands of modern radiotherapy, real time in-vivo dose measurement has recently attracted significant attention. A small, flexible optical fiber radiation dosimeter, with high signal-to-noise ...
  • Qin, Zhuang; Hu, Yaosheng; Ma, Yu; Zhao, Wenhui; Sun, Weimin; Zhang, Daxin; Chen, Ziyin; Lewis, Elfed (Optical Society of America, 2016)
    An investigation into a novel in-vivo PMMA (polymethyl methacrylate) plastic fiber-optic dosimeter for monitoring low doses of ionizing radiotherapy radiation in real time and for integrating measurements is presented. ...
  • Zhang, Haiyang; Ganchev, Ivan; Nikolov, Nikola S.; Ji, Zhanlin; O'Droma, Máirtín (Hindawi Publishing Corporation: Wiley Hindawi Partnership, 2017)
    With the development of ubiquitous computing, recommendation systems have become essential tools in assisting users in discovering services they would find interesting. This process is highly dynamic with an increasing ...
  • Qin, Zhuang; Hu, Yaosheng; Ma, Yu; Lin, Wei; Luo, Xianping; Zhao, Wenhui; Sun, Weimin; Zhang, Daxin; Chen, Ziyin; Wang, Boran; Lewis, Elfed (2016)
    An inorganic scintillating material plastic optical fiber (POF) dosimeter for measuring ionizing radiation during radiotherapy applications is reported. It is necessary that an ideal dosimeter exhibits many desirable ...
