  • Berkery, Elaine M (University of Limerick, 2016)
    Missing data occur regularly when data are collected for a variety of reasons such as participants refusing to answer question in surveys or machines failing to record measurements in a manufacturing process. The fact ...
  • Gallagher, Jason (University of Limerick, 2016)
    This research project investigated whether students’ conceptual understanding of algebra was improved with a taught intervention supported by digital pencasts. The motivation for this project was inspired by observing ...
  • Flanagan, Eileen (University of Limerick, 2016)
    Interest and achievement in mathematics is currently both a national and international concern. Interest in mathematics is low in comparison to other curricula subjects and achievement in mathematics is also poor when ...
  • Ward, Jonathan A; Fowler, Andrew C (SpringerOpen, 2016)
    Purpose: The polishing of cut lead glass crystal is effected through the dowsing of the glass in a mixture of two separate acids, which between them etch the surface and as a result cause it to be become smooth. In order ...
  • Moroney, Kevin M; Lee, William T.; O'Brien, Stephen BG; Suijver, Freek; Marra, Johan (SpringerOpen, 2016)
    The extraction of coffee solubles from roasted and ground coffee is a complex operation, the understanding of which is key to the brewing of high quality coffee. This complexity stems from the fact that brewing of coffee ...
  • Livingstone, Stephen J; Utting, Daniel J; Ruffell, Alastair; Clark, Chris D; Pawley, Steven; Atkinson, Nigel; Fowler, Andrew C (Nature Publishing Group, 2016)
    Recent proxy measurements reveal that subglacial lakes beneath modern ice sheets periodically store and release large volumes of water, providing an important but poorly understood influence on contemporary ice dynamics ...
  • Usher, Cara; Adams, Roisin; Schmitz, Susanne; Kieran, Jennifer; O'Flanagan, Darina; O'Donnell, Joan; Connolly, Kevin; Corcoran, Brenda; Butler, Karina; Barry, Michael; Walsh, Cathal Dominic (BioMed Central, 2016)
    Background: The aim of this study was to compare the cost effectiveness of the current Irish programme of universal BCG vaccination of infants versus a programme which considered selectively vaccinating high risk ...
  • Gleeson, James P.; O'Sullivan, Kevin P; Banos, Ranquel, A; Moreno, Yamir (American Physical Society, 2016)
    Online social media has greatly affected the way in which we communicate with each other. However, little is known about what fundamental mechanisms drive dynamical information flow in online social systems. Here, we ...
  • Hackett, A; Cellai, Davide; Gomez, S; Arenas, A; Gleeson, James P. (American Physical Society, 2016)
    We present an analytical approach for bond percolation on multiplex networks and use it to determine the expected size of the giant connected component and the value of the critical bond occupation probability in these ...
  • Dassios, Ioannis; Fountoulakis, Kimon; Gondzio, Jacek (Society for Industrial and Applied Mathematics, 2016)
    In this paper we are concerned with the solution of Compressed Sensing (CS) problems where the signals to be recovered are sparse in coherent and redundant dictionaries. We extend the primal-dual Newton Conjugate Gradients ...
  • Dowd, Kieran P; Kirwan, Robert P; Hannigan, Ailish; Purtill, Helen; O'Gorman, Clodagh S (BMJ Publishing Group, 2015)
    Objectives: To examine the relationship between maternal self-reported and measured height and weight, maternal perceived weight status and measured body mass index (BMI), and maternal perceived child weight status and ...
  • Klimas, Jan; Henihan, Anne Marie; McCombe, Geoff; Swan, Davina; Anderson, Rolande; Bury, Gerard; Dunne, Colum; Keenan, Eamon; Saunders, Jean; Williams Shorter, Gillian; Smyth, Bobby P; Cullen, Walter (Taylor and Francis, 2015)
    Objectives. Primary care is a key provider of long-term care for people who attend primary care for substance use treatment, especially those in methadone maintenance treatment. As many drink alcohol excessively, there is ...
  • Fowler, Andrew C; Kopteva, Natalia; Oakley, Charles (Society for Industrial and Applied Mathematics, 2006)
    We consider a deterministic model of landscape evolution through the mechanism of overland flow over an erodible substrate, using the St. Venant equations of hydraulics together with the Exner equation for hillslope erosion. ...
  • Robinson, Marguerite; Fowler, Andrew C; Alexander, A.J; O'Brien, S.B.G (American Institute of Physics, 2008)
    We describe a simple model of a bubbly two-phase flow which is able to explain why waves propagate downward when a pint of Guinness is poured, and also how the waves are generated. Our theory involves a physically based ...
  • Zammett, R.J; Fowler, Andrew C (Society for Industrial and Applied Mathematics, 2010)
    Spiral-shaped canyons on the polar ice caps of Mars are striking morphological features whose explanation is still mysterious. We pose a model for the kinetics at the ice-atmosphere interface based on the positive feedback ...
  • Kyrke-Smith, T.M; Katz, R.F; Fowler, Andrew C (American Geophysical Union, 2015)
    Observations have long associated ice streams with the presence of meltwater at the bed. More recently, theoretical models have been able to reproduce ice stream behavior as a consequence of the coupled dynamics of ice and ...
  • Khaleque, Tania S; Fowler, Andrew C; Howell, P D; Vynnycky, M (American Institute of Physics, 2015)
    Motivated by convection of planetary mantles, we consider a mathematical model for Rayleigh-Benard convection in a basally heated layer of a fluid whose viscosity depends strongly on temperature and pressure, defined in ...
  • Lee, William T.; Fowler, Andrew C; Power, O; Healy, S; Browne, J (American Institute of Physics, 2010)
    Polycrystalline silicon fuses are one time programmable memory elements which allow the calibration of integrated circuits at wafer and package level. We present a zero-dimensional lumped parameter model of the programming ...
  • Walsh, Cathal Dominic (Univerza v Ljubljani, Fakulteta za Druzbene Vede, 2006)
    Latent variable models have been used extensively in the social sciences. In this work a latent class analysis is used to identify syndromes within Alzheimer's disease. The fitting of the model is done in a Bayesian framework, ...
  • Cunningham, C.J; Walsh, J.B; Coakley, D; Walsh, Cathal Dominic; Connolly, C; Murphy, M; Murphy, C (Irish Medical Organisation, 2008)
    Data on the life expectancy of elderly people in long term care facilities will be important for effective service planning and monitoring quality of care. To date there are no such data from an Irish perspective. A random ...
