  • Moroney, Kevin M.; O’Connell, Ken; Meikle-Janney, Paul; O’Brien, Stephen B.G.; Walker, Gavin M.; Lee, William T. (Public Library of Science, 2019)
    Achieving a uniform extraction of soluble material from a porous matrix is a generic problem in various separation and filtration operations, with applications in the food processing, chemical and pharmaceutical industries. ...
  • Moroney, Kevin M.; Lee, William T.; O'Brien, Stephen B.G.; Suijver, F.; Marra, Johan (Society for Industrial and Applied Mathematics, 2016)
    Extraction of coffee solubles from roast and ground coffee is a highly complex process, depending on a large number of brewing parameters. We consider a recent, experimentally validated, model of coffee extraction, describing ...
  • 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 ...
  • Devereux, Michael (University of Limerick, 2011)
    Foam and bubbles are ubiquitous in industry and nature. They have a wide range of applications but are also an undesirable product of certain processes. This thesis considers two individual industrial problems with the ...
  • Moroney, Kevin M.; Lee, William T.; O'Brien, Stephen B.G.; 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 ...
  • Gleeson, James P.; Ward, Jonathan A; O'Sullivan, Kevin P.; Lee, William T. (American Physical Society, 2014)
    Heavy-tailed distributions of meme popularity occur naturally in a model of meme diffusion on social networks. Competition between multiple memes for the limited resource of user attention is identified as the mechanism ...
  • Murphy, Ellen (University of Limerick, 2014)
    Applied mathematicians have long sourced problems from industrial processes. The relationship between mathematics and industry is mutually beneficial. Mathematical models provide industry with invaluable insights into ...
  • Cooker, Mark; Cribbin, Laura B.; Dellar, Paul; Fitt, Alistair; Gaburro, Romina; Gibb, Tony; Kennedy, James; King, John; Kubat, Irnis; Lapin, Vladimir Nikolaevich; Lee, William T.; Murphy, Ellen; Nolan, Clifford J.; Parker, Joseph; Power, Oliver; Timoney, Catherine M. (2011)
    Background. The development of haptic touchscreens, that is touchscreens with the ability to mimic the feel of a real keyboard, would be a significant advance in the mobile phone and tablet market. This report investigates one ...
  • Moroney, Kevin M. (Univeristy of Limerick, 2016)
    Industrial and manufacturing processes are an abundant source of rich and complex problems amenable to investigation with mathematical logic and techniques. Once a problem is identi ed and the right questions are ...
  • Lee, William T.; Kaar, S.; O'Brien, Stephen B.G. (American Assocation of Physics Teachers, 2018)
    A surprising phenomenon witnessed by many is the sinking bubbles seen in a settling pint of stout beer. Bubbles are less dense than the surrounding fluid so how does this happen? Previous work has shown that the explanation ...
  • Cregan, Vincent; Lee, William T.; Clune, Louise (SpringerOpen, 2017)
    A soft sensor for measuring product quality in the Bayer process has been developed. The soft sensor uses a combination of historical process data recorded from online sensors and laboratory measurements to predict a key ...
  • Sedakov, Roman Olegovich (University of Limerick, 2012)
    The present thesis studies the problem of existence and stability of spatial periodic solutions of the extended Cahn–Hilliard equation. The extended Cahn–Hilliard equation is a well-known model that describes the process ...
