1/f noise in MgO double-barrier magnetic tunnel junctions
(2011)Low frequency noise has been investigated in MgO double-barrier magnetic tunnel junctions (DMTJs) with tunneling magnetoresistance (TMR) ratios up to 250% at room temperature. The noise shows a 1/f frequency spectrum and ... -
3D visualisation of confocal flourescence microscopy data
(2004)Confocal microscopes are able to non-invasively capture sub-micron details of fluorescent-labelled specimens at multiple depths, but there is a lack of applications capable of displaying this collected information in a ... -
Adaptive medial-axis approximation for sphere-tree construction
(2004)Hierarchical object representations play an important role in performing efficient collision handling. Many different geometric primitives have been used to construct these representations, which allow areas of interaction ... -
Alternating and direct current characterization and photoinduced absorption studies of modified conjugated polymer thin films
(Journal of Applied Physics, 2004)Control of interchain separation enables the optical properties of polymer thin films to be altered. We present a thin film preparation technique that increases the free volume fraction in spin coated polymer thin films ... -
Animating humans on handlheld devices for interactive gaming
(2005)This paper examines the implementation and efficacy of impostor-based techniques on smallscreen devices, and compares their effectiveness with that of the same techniques when used on desktop computers. Firstly, a ... -
An Approach to Aggregating Ensembles of Lazy Learners that Supports Explanation
(Trinity College Dublin, Department of Computer Science, 2002-04)Ensemble research has shown that the aggregated output of an ensemble of predictors can be more accurate than a single predictor. This is true also for lazy learning systems like Case-Based Reasoning (CBR) and ... -
An Automatically Composable OWL Reasoner for Resource Constrained Devices
(IEEE, 2009)Centralized semantic sensor network systems gradually show performance degradation as the scale of the sensor network increases. Thus systems based on distributed approaches with local, autonomous management features ... -
Awareness of Deficits in Traumatic Brain Injury: A Multidimensional Approach to Assessing Metacognitive Knowledge and Online-Awareness
(Cambridge University Press, 2007)Recent models of impaired awareness in brain injury draw a distinction between metacognitive knowledge of difficulties and online awareness of errors (emergent and anticipatory). We examined performance of 31 Traumatic Brain ... -
Building on IUCN regional red lists to produce lists of species of conservation priority: A model with Irish bees
(Society for Conservation Biology, 2007)A World Conservation Union (IUCN) regional red list is an objective assessment of regional extinction risk and is not the same as a list of conservation priority species. Recent research reveals the widespread, but incorrect, ... -
Caffeic acid phenethyl ester modulates Helicobacter pylori-induced nuclear factor-kappa B and activator protein-1 expression in gastric epithelial cells
(Nature, 2005)Caffeic acid phenethyl ester (CAPE), an active component of propolis from honeybee hives (honeybee resin), has anti-inflammatory, anti-carcinogenic and anti-bacterial properties. This study was designed to investigate the ... -
Carbon nanotube based modified electrode biosensors. Part 1. Electrochemical studies of the flavin group redox kinetics at SWCNT/glucose oxidase composite modified electrodes.
(Electrochemical Science Group, 2008)The redox behaviour of glucose oxidase adsorbed on glassy carbon electrodes which have been modified with a dispersed mesh of single wall carbon nanotubes is probed both qualitatively and quantitatively using cyclic ... -
Characterisation of Macro-porous Silicon for Electronic Applications
(SPIE, 2003)Micro-Raman spectroscopy was used in this study for the analysis of the influence of process conditions on the strain and stress in macro-porous layers. As expected, it was found that oxidation results in significant wafer ... -
Characterization of RP1L1, a highly polymorphic paralog of the retinitis pigmentosxa 1 (RP1) gene
(Molecular Vision, 2003)PURPOSE: To determine the full-length sequence of a gene with similarity to RP1 and to screen for mutations in this newly characterized gene, named retinitis pigmentosa 1-like 1(RP1L1). Since mutations in the RP1 gene cause ... -
Charmonium at high temperature in two-flavor QCD
(American Physical Society, 2007)We compute charmonium spectral functions in 2-flavor QCD on anisotropic lattices using the maximum entropy method. Our results suggest that the S-waves (J= and c) survive up to temperatures close to 2Tc, while the P-waves ... -
Charmonium properties in the quark-gluon plasma
(2007)We present results for charmonium correlators and spectral functions in 2-flavour QCD on anisotropic lattices. Our results indicate that the S-waves (J/y and hc) survive up to temperatures close to 2Tc, while the P-waves ... -
Charmonium spectral functions in Nf=2 QCD
(Proceedings of Science, 2005)We report on a study of charmonium at high temperature in 2-flavour QCD. This is the first such study with dynamical fermions. Using an improved anisotropic lattice action, spectral functions are extracted from correlators ... -
Charmonium spectroscopy on dynamical anisotropic lattices
(Elsevier, 2006)We present a first study of the charmonium spectrum on Nf = 2 dynamical, anisotropic lattices. We take advantage of all-to-all quark propagators to build spatially extended interpolating operators to increase the overlap ... -
Childhood Helicobacter pylori infection and growth impairment in developing countries: a vicious cycle?
(American Academy of Paediatrics, 2007)We hypothesize that infection with the gastric pathogen Helicobacter pylori in children in developing countries is the initiator of a vicious cycle of events that result ultimately in malnutrition and growth impairment. ... -
Computer Graphical Interfaces, Reflection and the Teaching and Learning of Music Composition - a Holistic Study.
(Trinity College Dublin.School of Computer Science and Statistics.COMPUTER SCIENCE, 2006)This thesis is a holistic study in the area of teaching and learning of music composition for children in the age range eight to eleven years. It investigates the role of graphical computer technology within the framework ... -
A context information service using ontology-based queries
(2004)Ubiquitous computing environments have the potential to provide rich sources of information about a user and their surroundings. However, the nature of context information means that it must be gathered in an ad-hoc ...
