    Traffic-Aware Adaptive Polling Mechanism for High Performance Packet Processing Hristo Trifonov The work described in thesis concerns the topical subject area of SDN (software defined networking), in particular the Data ...
  • Halton, Mark; Scharrer, Martin; Scanlan, Tony (IET Institute of Engineering and Technology, 2008)
    This paper considers the application of the discrete-time structured singular value to assess the robustness of systems subject to real parametric uncertainties. Since the associated uncertainty set is strictly real, ...
  • Kam, Wern; O'Sullivan, Kieran; O'Keeffe, Mary; O'Keeffe, Sinead; Waleed, Mohammed S; Lewis, Elfed (Elsevier, 2017)
    A mechanically robust and compact novel optical fiber sensor system is described to monitor the bending of the lower back bone in both sagittal and frontal planes. Both bending modes are monitored through the change of the ...
  • 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 ...
  • O'Brien, Vincent; Scanlan, Anthony G; Mullane, Brendan (Springer, 2017)
    This paper presents a dynamic element matching (DEM) decoder incorporating both intersymbol interference (ISI) and mismatch error shaping. From the analysis of ISI error in multi-bit DACs, an algorithm is developed ...
  • Effler, Simon; Halton, Mark; Rinne, Karl (PCIM Europe, 2009)
    The trend in next-generation switched-mode power supplies will lead to modular, scalable solutions which can deliver power efficiently over a wide range of operation. Multiple parallel power stages, often called phases ...
  • Effler, Simon; Halton, Mark; Kelly, Anthony; Rinne, Karl (PCIM Europe, 2008)
    This paper focuses on the application of a generalized predictive control (GPC) law design technique for digitally controlled DC-DC converters. The unconstrained GPC control law presented is based on a minimization of ...
  • Arshak, Khalil; Twomey, K. (MDPI, 2002)
    This paper documents the manufacture and testing of a humidity sensor based on a combination of In2O3/SiO. A number of different sensor samples have been produced by thermal deposition and the effect of varying the vacuum ...
  • Scharrer, Martin; Halton, Mark; Scanlan, Tony; Rinne, Karl (IEEE Computer Society, 2010)
    This paper proposes a state-dependent Analog-to-Digital Conversion (ADC) scheme for digitally isolated Switched Mode Power Converters (SMPCs). The SMPC voltage range is subdivided into three different regions corresponding ...
  • Scharrer, Martin; Halton, Mark; Scanlan, Tony; Rinne, Karl (IEEE Computer Society, 2012)
    An efficient high-speed bi-directional data transmission scheme for isolated AC-DC and DC-DC switched mode power converters is presented. The bi-directional scheme supports fast, efficient and reliable transmission of ...
  • Scharrer, Martin; Halton, Mark; Scanlan, Martin (IEEE Computer Society, 2009)
    This paper proposes a new FPGA based architecture for digital pulse width modulators which takes advantage of dedicated digital clock manager (DCM) blocks present in modern FPGAs and applies manual placement techniques ...
  • Scharrer, Martin; Halton, Mark; Scanlan, Tony (IEEE Computer Society, 2008)
    This paper details the design of a digitally controlled isolated SMPC containing a novel bi-directional data transmission scheme The bi-directional data transmission scheme avoids the effects of opto-coupler aging, ...
  • Scanlan, Tony; Halton, Mark (Emerald Group Publishing Ltd, 2011)
    The purpose of this paper is to present a hierarchical circuit synthesis system with a hybrid deterministic local optimization multi-objective genetic algorithm (DLO-MOGA) optimization scheme for system-level synthesis. ...
  • Mooney, James; Halton, Mark; Iordanov, Petar; O'Brien, Vincent (IEEE Computer Society, 2015)
                               Multi-bit sigma-delta based digital pulse width modulators (DPWM) are used in the control of DC-DC converters in order to achieve high resolution and therefore high output voltage accuracy at ...
  • Mooney, James; Halton, Mark; Mahdi, Abdulhussain E (IEEE Computer Society, 2010)
    This paper describes a Digital Signal Processor (DSP) whose architecture has been purposely developed for executing power converter control algorithms. It is intended for use in the control of multi-phase or multi-rail ...
  • Mooney, James; Effler, Simon; Halton, Mark; Mahdi, Abdulhussain E (IEEE Computer Society, 2010)
    This paper proposes a hardware modification to a standard Digital Signal Processor (DSP) that enables it to digitally control multiple DC-DC converters with non-integer switching frequency ratios. The modified DSP overcomes ...
  • Iordanov, Petar; Hayes, Martin J.; Halton, Mark (IEEE Computer Society, 2003)
    The paper introduces a new approach for the computation of a lower bound on the structured singular value (SSV), μ in the presence of purely real and mixed/complex uncertainties. The approach utilises a frequency sweeping ...
