  • Chen, Huan; Marques-Silva, Joao (Association for Computing Machinery, 2012)
    Boolean function bi-decomposition is pervasive in logic synthesis. Bi-decomposition entails the decomposition of a Boolean function into two other simpler functions connected by a simple two-input gate. Existing solutions ...
  • McGloughlin, Timothy M.; Doyle, Barry J. (Lippincott Williams & Wilkins, 2010)
    Abdominal aortic aneurysm (AAA) rupture remains a significant cause of death in the developed world. Current treatment approaches rely heavily on the size of the aneurysm to decide on the most appropriate time for clinical ...
  • Lang, Michael; Fitzgerald, Brian (Taylor & Francis Ltd, 2006)
    Despite claims in the literature that "traditional" methods and techniques are inadequate and poorly matched to the demands of the Web design context, the findings from a field survey of Web/hypermedia systems designers ...
  • Shokry, Hesham; El-Boghdadi, Hatem M.; Shaheen, Samir I. (Association for Computing Machinery, 2008)
    Producing efficient and compact code for embedded DSP processors is very important for nowadays faster and smaller size devices. Because such processors have highly irregular data-path, conventional code generation techniques ...
  • Leahy, Martin J.; O'Doherty, Jim; Nilsson, Gert E.; Henricson, Joakim; Anderson, Chris; Sjoberg, Folke (SPIE—The International Society for Optical Engineering, 2007)
    A low-cost, noninvasive means of imaging red blood cells shows promise in applications aimed at assessing tissue viability.
  • Mahdi, Abdulhussain E; Picovici, Dorel (Springer, 2010)
    This article proposes a new output-based method for non-intrusive assessment of speech quality of voice communication systems and evaluates its performance. The method requires access to the processed (degraded) speech ...
  • Lyons, G.M.; Arshak, Khalil; Cavanagh, Leon M.; Gaidan, Ibrahim; Moore, Edward G.; Clifford, S.A.; Phelan, R.; Cunniffe, Colm; Harris, John A. (IEEE Computer Society, 2004)
    The response of screen-printed thick-films of NiO/TiO2 to organic solvent vapours was studied. It was found that these films displayed a significant resistance change in response to the vapours even at room temperature. ...
  • Hagan, Kerry L (2013)
    Morphons and Bions is a real-time, computer-generated work that uses white noise as the fundamental synthesis component combined with classical synthesis techniques. Random and stochastic processes control the synthesis ...
  • Murray, Derek M (University of Limerick, 2013)
    The design specifications for power converters are getting continuously tighter, keeping pace with the ever-increasing power requirements of the loads they supply. A step-down DC-DC converter used in modern computing ...
  • Mahdi, Abdulhussain E; Faggion, L (IOP Publishing, 2011)
    This paper describes a new low-cost,  low-noise displacement current sensor developed for non-contact measurements of human biopotentials and well suited for detection of human presence applications. The sensor employs a ...
  • Al-Tawarah, Yasin; MacKenzie, Gilbert (IWSM, 2003)
    In longitudinal studies with a set of continuous or ordinal repeated response variables it may be convenient to summarize the outcome as a threshold event. Then, the time to this event becomes of interest. In this paper ...
  • MacKenzie, Gilbert; Do Ha, II; Lee, Youngjo (IWSM, 2003)
    Correlated survival times may be modelled by introducing a random effect, or frailty, component into the hazard function. For multivariate survival data we extend a non-PH model, the generalized time-dependent logistic (GTDL) ...
  • Al-Tawarah, Yasin; MacKenzie, Gilbert (IWSM, 2005)
    In this paper we investigate the use of accelerated Weibull hazard model. We compare it with Logistic Accelerated Hazard model. The models are used to analyze survival data from the Northern Ireland lung cancer study ...
  • Donovan, J; Murphy, Eamonn (Irish Statistical Association, 2007)
    Commercial irradiation typically involves applying electron beam or gamma radiation to a product with a view to sterilizing the product and killing any bacteria present. This is extremely important in the medical ...
  • Tierney, Áine P. (University of Limerick, 2012)
    Abdominal Aortic Aneurysms (AAAs) is a permanent and irreversible dilation of the infrarenal section of the aorta. AAA’s are generally asymptomatic, until rupture of the AAA wall occurs. Rupture can lead to large abdominal ...
  • Mc Caffery, Fergal; Wilkie, F.G.; McFall, Donald (2004)
    This presentation discusses statistical findings obtained from a survey of the state of software development practices within Northern Ireland (NI). The survey was developed and conducted by staff from the Centre for ...
  • Arshak, Khalil; Cunniffe, Colm; Moore, Edward G.; Cavanagh, Leon M.; Harris, John A. (IEEE Computer Society, 2005)
    Presented in this paper is a process for manufacturing copper electrode patterns on alumina substrates using thin film deposition, spin coating and printed circuit board (PCB) etching techniques. The process was used for ...
  • Tai, Guangfu; Williams, Peter (2009)
    Appropriate modelling for patient arrival is the first step in investigation of factors contributing to waiting time of both patients and the doctor in clinics. In previous practice, scheduled patient’s unpunctuality (i.e., ...
  • Lynch, Andrew (University of Limerick, 2011)
    Small to Medium Enterprise (SME) performance is a function of the composite of the decision-making processes within the enterprise. Owner managers are conscious of the gap in their decision-making efficacy and acknowledge ...
  • Ryan, Adrian P.; McCarthy, Oliver (IEEE Computer Society, 2004)
    The main problem in extending continuous-time filtering to higher frequencies is the sensitivity of high-frequency filters to analog integrator nonidealities such as finite dc gain and parasitic poles. The use of a ...
