  • Connelly, Michael J. (IOP Publishing, 2015)
    Band-gap shrinkage is an important effect in semiconductor lasers and optical amplifiers. In the former it leads to an increase in the lasing wavelength and in the latter an increase in the gain peak wavelength as the bias ...
  • O'Hare, Daniel; Scanlan, Anthony G.; Thompson, Eric; Mullane, Brendan (IEEE Computer Society, 2017)
    This paper presents design analysis and insights for a new continuous-time input pipeline (CTIP) analog-to-digital converter (ADC) architecture that has enhanced bandwidth. An all-pass filter-based analog delay in ...
  • Lei, Yiming (University of Limerick, 2010)
    The major weakness of frequently used Orthogonal Frequency Division Multiplexing (OFDM) signals is their high sensitivity to nonlinear amplification process when they are driven through RF power amplifiers (PAs). In research ...
  • Quinn, Declan (University of Limerick, 2009)
    In this thesis, Blind Source Separation is studied in the context of both instantaneous and convolutive mixtures of musical sources. In order to appreciate how the application of BSS techniques to music may differ from ...
  • 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 ...
  • Kamel Boulos, Maged N; Rocha, Artur; Martins, Angelo; Escriche Vicent, Manuel; Bolz, Armin; Feld, Robert; Tchoudovski, Igor; Braecklein, Martin; Nelson, John; Ó Laighin, Gearóid; Sdogati, Claudio; Cesaroni, Francesca; Antomarini, Marco; Jobes, Angela; Kinirons, Mark (BioMed Central, 2007)
    Recent advances in mobile positioning systems and telecommunications are providing the technology needed for the development of location-aware tele-care applications. This paper introduces CAALYX – Complete Ambient Assisted ...
  • Shahid, Shahjahan; Walker, Jacqueline (Elsevier, 2008)
    In this paper, an improved approach to blind deconvolution of LTI systems incorporating phase unwrapping is presented. The method can recover a noise-free estimate of the logarithm of the system transfer function which ...
  • Arshak, Khalil; Twomey, K.; Egan, D. (MDPI, 2002)
    A ceramic thick film humidity sensor, produced from MnZn ferrite, is presented. The proposed sensing mechanism is a combination of proton hopping, hydronium diffusion, and vacancy donor traps releasing electrons into the ...
  • Cantoni, Antonio; Walker, Jacqueline (IEEE Computer Society, 2006)
    We characterize the metastability measurement system [8] in which asynchronous data input and sampling clock frequencies trigger metastability. We develop the equation describing the time interval between data and clock ...
  • Penner, Crystal; Hoehr, Cornelia; O'Keeffe, Sinéad; Woulfe, Peter; Duzenli, Cheryl (IEEE Computer Society, 2017)
    A characterization study was carried out to determine if a novel, millimeter sized Terbium-activated Gadolinium Oxysulfide optical fibre detector has potential for future use in proton dosimetry. Preliminary studies ...
  • 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 ...
  • Sporea, Dan; Mihai, Laura; Vâţă, Ion; McCarthy, Denis; O'Keeffe, Sinéad; Lewis, Elfed (MDPI, 2014)
    The paper presents a set of tests carried out in order to evaluate the design characteristics and the operating performance of a set of six X-ray extrinsic optical fiber sensors. The extrinsic sensor we developed is intended ...
  • Mahdi, Abdulhussain E.; Joorabchi, Arash (Sage Publications, 2010)
    Topical indexing of documents with keyphrases is a common method used for revealing the subject of scientific and research documents to both human readers and information retrieval tools, such as search engines. However, ...
  • Joorabchi, Arash; Mahdi, Abdulhussain E. (Emerald, 2013)
    Purpose - This paper aims to report on the design and development of a new approach for automatic classification and subject indexing of research documents in scientific digital libraries and repositories (DLR) according ...
  • Dhirani, Lubna Luxmi; Newe, Thomas; Lewis, Elfed; Nizamani, Shahzad (IEEE Computer Society, 2017)
    The Internet of Things (IoT) has presented many new dimensions to information technology and data communications and has helped to develop the concepts of Smart City, Smart Travel, Smart Surveillance, Smart Health, ...
  • Ji, Zhanlin; Ganchev, Ivan; O'Droma, Máirtín; Zhao, Li; Zhang, Xuegi (MDPI, 2014)
    This paper presents the generic concept of using cloud-based intelligent car parking services in smart cities as an important application of the Internet of Things (IoT) paradigm. This type of services will become an ...
  • Ji, Zhanlin; Ganchev, Ivan; O'Droma, Máirtín; Zhang, Xin; Zhang, Xueji (Hindawi Publishing Corporation, 2014)
    Based on the user-centric paradigm for next generation networks, this paper describes a ubiquitous mobile healthcare (uHealth) system based on the ISO/IEEE 11073 personal health data (PHD) standards (X73) and cloud computing ...
  • Zeng, Liaoyuan; McGrath, Sean; Liu, Guanghui (SpringerOpen, 2014)
    A critical objective of cognitive radio (CR) system is to enhance the spectrum efficiency, and one of the key factors that can determine the spectrum efficiency is the system spectrum sensing performance with respect to ...
  • Sivčev, Satja; Rossi, Matija; Coleman, Joseph; ; Dooly, Gerard; Toal, Daniel (MDPI, 2018)
    Work-class ROVs equipped with robotic manipulators are extensively used for subsea intervention operations. Manipulators are teleoperated by human pilots relying on visual feedback from the worksite. Operating in a remote ...
