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 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, ... -
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 ... -
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 ... -
Crowd and group simulation with levels of detail for geometry, motion and conversational behaviour
(2002)Work on levels of detail for human simulation has occurred mainly on a geometrical level, either by reducing the numbers of polygons representing a virtual human, or replacing them with a two-dimensional imposter. ... -
Danger! men at work: a study of the underepresentation of women in third-level engineering
(Department of Education and Science, 2004) -
Design and manufacture of surface acoustic wave sensors for real-time weigh-in-motion.
(IEEE, 2005)This paper presents the design and manufacture of surface acoustic wave (SAW) strain sensors which can be produced in a university environment. These sensors can be interrogated wirelessly and operated without a power ... -
Development of a vessel-mimicking material for use in anatomically realistic Doppler flow phantoms
(2011)Polyvinyl alcohol cryogel, (PVA-C) is presented as a vessel mimicking material for use in anatomically realistic Doppler flow phantoms. Three different batches of 10 % wt PVA-C containing (i) PVA-C alone, (ii) PVA C with ...
