  • Ramsey, David (Politechnika Wroclawska * Oficyna Wydawnicza, 2009)
    In many evolutionary games, such as parental care games, the length of time spent playing a realisation of the game is dependent on the strategy of an individual. Also, the payoff of a deserting male cannot be defined ...
  • Ramsey, David (Elsevier, 2010)
    This article presents a game theoretic model of parental care which models the feedback between patterns of care and the operational sex ratio. It is assumed here that males can be in one of two states: searching for a ...
  • MacKenzie, Gilbert; Conde, Susana (IWSM, 2016)
    We develop a Smooth Lasso for sparse, high dimensional, contingency tables and compare its performance with the usual Lasso and with the now classical backwards elimination algorithm. In simulation, the usual Lasso had ...
  • Conde, Susana; MacKenzie, Gilbert (IWSM, 2011)
    We consider several least absolute shrinkage and selection operator (LASSO) penalized likelihood approaches in high dimensional contingency tables and with hierarchical log-linear models. These include the proposal of a ...
  • 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, ...
  • Cellai, Davide; Fima, Andrzej Z; Lawlor, Aonghus; Dawson, Kenneth A (AIP Publishing, 2011)
    Glass-forming liquids have been extensively studied in recent decades, but there is still no theory that fully describes these systems, and the diversity of treatments is in itself a barrier to understanding. Here we ...
  • Sheikhi, Ali; Ramsey, David (IWSM, 2012)
    A single nucleotide polymorphism or SNP is a site of the genome where variation occurs within a population. Almost all SNPs have only two alleles (variants). In this work, we consider a statistical method based on a ...
  • Fennell, Peter G.; Melnik, Sergey; Gleeson, James P. (American Physical Society, 2016)
    Continuous-time Markov process models of contagions are widely studied, not least because of their utility in predicting the evolution of real-world contagions and in formulating control measures. It is often the case, ...
  • Guasoni, Paolo; Mayerhofer, Eberhard (Wiley and Sons Ltd, 2019)
    When trading incurs proportional costs, leverage can scale an asset's return only up to a maximum multiple, which is sensitive to its volatility and liquidity. In a model with one safe and one risky asset, with constant ...
  • Kopteva, Natalia (American Mathematical Society, 2014)
    We give a counterexample of an anisotropic triangulation on which the exact solution has a second-order error of linear interpolation, while the computed solution obtained using linear finite elements is only first-order ...
  • Doeva, Olga; Gaburro, Romina; Lionheart, William R. B.; Nolan, Clifford J. (Taylor & Francis, 2020)
    We study the inverse problem in Optical Tomography of determining the optical properties of a medium ⊂ Rn, with n ≥ 3, under the so-called diffusion approximation. We consider the time-harmonic case where is probed ...
  • Alessandrini, Giovanni; Gaburro, Romina (Taylor & Francis, 2009)
  • Al-tawarah, Yasin; MacKenzie, Gilbert (IWSM, 2002)
    The survival function of the logistic proportional hazards (PH) regression model, MacKenzie (1996), is obtained. A general likelihood for interval censored survival data which depends only on various closed forms of ...
  • MacKenzie, Gilbert (IWSM, 2002)
    The near non-identifiability of one of the parameters in the Generalized Time-Dependent Logistic (GTDL) Survival Model (MacKenzie, 1996, 1997) is discussed. A new canonical 3-parameter logistic model survival model, in ...
  • Kopteva, Natalia (Springer, 2020)
    Lower a posteriori error bounds obtained using the standard bubble function approach are reviewed in the context of anisotropic meshes. A numerical example is given that clearly demonstrates that the short-edge jump residual ...
  • Ryan, Veronica (University of Limerick, 2018)
    This research study investigated student performance in mathematics during the transition from primary to post-primary school. Academic achievement in mathematics was measured using a standardised test at the end of sixth ...
  • Lynch, Julie; Prihodova, Lucia; Dunne, Pádraic J.; O'Leary, Caoimhe; Breen, Rachel; Carroll, Áine; Walsh, Cathal Dominic; McMahon, Geraldine; White, Barry (BMJ Publishing Group, 2018)
    Objectives Rates of burnout and stress in healthcare practitioners are steadily increasing. Emergency department (ED) staff are particularly susceptible to such poor outcomes. Mantra meditation (MM) may contribute to ...
  • O'Sullivan, David J.P.; O'Keeffe, Gary J.; Fennell, Peter G.; Gleeson, James P. (Frontiers Media, 2015)
    The spreading of behavior, such as the adoption of a new innovation, is influenced by the structure of social networks that interconnect the population. In the experiments of Centola [15], adoption of new behavior was shown ...
  • McInerney, Niall (University of Limerick, 2019)
    In the first part of this thesis, mathematical models describing solvent and drug diffusion in glassy polymers are investigated using both numerical and approximate methods. These models are analysed using formal ...
  • O'Keeffe, Gary J. (University of Limerick, 2018)
    Solar-thermal collectors capture solar energy and convert it into heat energy. Several types of solar-thermal collectors have been used to harness solar radiation in both residential, electricity generation, and industrial ...
