  • Shaikh, Maha; Cornford, Tony (2008)
    Open-sourcing is a relatively new term and indicates a less explored theme within the overall perspective of global sourcing. Until recently the term has usually been taken to refer to commercially controlled and created ...
  • Yu, Yijun; Tun, Thein Than; Tedeschi, Alessandra; Nuseibeh, Bashar (IEEE Computer Society, 2011)
    When software systems are verified against security requirements, formal and informal arguments provide a structure for organizing the software artifacts. Our recent work on the evolution of security-critical software ...
  • Clohessy, Trevor; Acton, Thomas (2013)
    This paper describes research-in-progress that explores the applicability and implications of cloud computing in the creation of business value through open innovation. Both the cloud computing and open innovation paradigms ...
  • Meisel, Hans; Fitzgerald, Richard J. (Cambridge University Press, 2000)
    Opioid agonistic and antagonistic peptides which are inactive within the sequence of the precursor milk proteins can be released and thus activated by enzymatic proteolysis, for example during gastrointestinal digestion ...
  • Groba, Christin; Clarke, Siobhán (IEEE Computer Society, 2011)
    Dynamic service composition has emerged as a promising approach to build complex runtime-adaptable applications as it allows for binding service providers only shortly before service execution. However, the dynamic and ...
  • Zhernovaya, Olga (University of Limerick, 2015)
    Light scattering in biological tissues and blood leads to a reduction in imaging spatial resolution, imaging depth and contrast of optical imaging techniques. Refractive index mismatch between erythrocytes and blood plasma ...
  • Chiavaroli, Stefano; Newport, David; Woulfe, Bernie (American Institute of Physics, 2010)
    A barrier in scaling laboratory processes into automated microfluidic devices has been the transfer of lab based assays: where engineering meets biological protocol. One basic requirement is to reliably and accurately ...
  • Yan, Yongji; Zhang, Xu; Li, Haopeng; Ma, Yu; Xie, Tianci; Qin, Zhuang; Liu, Shuangqiang; Sun, Weimin; Lewis, Elfed (MDPI, 2018)
    A novel ultraviolet (UV) optical fiber sensor (UVOFS) based on the scintillating material La2O2S:Eu has been designed, tested, and its performance compared with other scintillating materials and other conventional UV ...
  • Sporea, Dan; Sporea, Adelina; O'Keeffe, Sinéad; McCarthy, Denis; Lewis, Elfed (INTECH, 2012)
    By their very nature, optical fibers and, by extension, intrinsic and extrinsic optical fiberbased sensors are promising devices to be used in very different and complex environments considering their characteristics ...
  • Duraibabu, Dinesh Babu; Poeggel, Sven; Omerdić, Edin; Capocci, Romano; Lewis, Elfed; Newe, Thomas; Leen, Gabriel; Toal, Daniel; Dooly, Gerard (MDPI, 2017)
    A miniature sensor for accurate measurement of pressure (depth) with temperature compensation in the ocean environment is described. The sensor is based on an optical fibre Extrinsic Fabry-Perot interferometer (EFPI) ...
  • Newe, Thomas; O'Connell, Eoin; Meere, Damien; Yuan, Hongwei; Leen, Gabriel; O'Keeffe, Sinéad; Lewis, Elfed (Society of Photo-optical Instrumentation Engineers (SPIE), 2016)
    Recent advancements in cloud computing technologies in the context of optical and optical fibre based systems are reported. The proliferation of real time and multi-channel based sensor systems represents significant growth ...
  • Poeggel, Sven; Tosi, Daniele; Duraibabu, Dinesh Babu; Leen, Gabriel; McGrath, Deirdre; Lewis, Elfed (MDPI, 2015)
    This article is focused on reviewing the current state-of-the-art of optical fibre pressure sensors for medical applications. Optical fibres have inherent advantages due to their small size, immunity to electromagnetic ...
  • Fabian, Matthias (University of Limerick, 2013)
    This work describes the development of a fibre-optic fluid concentration sensor that is based on evanescent field absorption. In addition, a second optical sensor principle is investigated by means of the development of ...
  • Zawawi, Mohd Anwar (University of Limerick, 2015)
    Health monitoring applications in clinical environment include various areas such as respiration assessment, heart rate monitoring, gait monitoring, spine bending as well as lower and upper limb motion detections. In human ...
  • Clifford, John (University of Limerick, 2011)
    This work describes the investigation and development of an optical fibre gas sensor based on mid infra red absorption spectroscopy. The sensor is suitable for monitoring the gases present in the exhaust emissions of a ...
  • O'Keeffe, Sinéad; Dooley, Gerard; Fitzpatrick, Colin; Lewis, Elfed (IOP Publishing, 2005)
    The use of optical fibres for the measurement of ozone based on the optical absorption of both UV light at 254nm and visible light at 600nm is investigated and tested. Calculations based on the Beer-Lambert Law are also ...
  • O'Keeffe, Sinéad; Fitzpatrick, Colin; Fernandez, Fernandez A.; Lewis, Elfed; Al-Shamma'a, Ai (IOP Publishing, 2007)
    The radiation-induced attenuation in poly-methylmethacrylate (PMMA) based plastic optical fibres is monitored online during exposure to gamma radiation, in an investigation in to their use as an intrinsic real-time gamma ...
  • McCarthy, Denis (University of Limerick, 2015)
    In this thesis, the development of a novel fibre optic sensor for measuring X-ray radiation in radiotherapy is investigated. The proposed sensor is based on utilising PMMA optical fibres which are coated with an X-ray ...
  • O'Keeffe, Sinéad; Zhao, W.; Sun, W.; Zhang, Daxin; Qin, Z.; Chen, Z.; Ma, Y.; Lewis, Elfed (IEEE Computer Society, 2016)
    A novel real-time optical fibre X-Ray dosimeter for monitoring the radiation pulses delivered from a clinical linear accelerator (Linac) is presented. The primary focus of the sensor is to measure low doses of ionising ...
  • Sai, Ashish Rajendra; Buckley, Jim; Le Gear, Andrew (2018)
    Proof Of Work Blockchains such as Bitcoin and Ethereum exhibit a low Transaction Per Second (TPS) that impacts the scalability of the blockchain. Manipulating the block creation time can yield a higher TPS. A lower block ...
