Quantifying Uncertainties in Cargo Deck Deflections from Distributed Fiber Optic Strain Data
(2023)A variety of sensing modalities and sensor technologies are used to monitor the health, assess the condition, and quantify the life span of civil infrastructure. Among the more recent technologies utilized for health ... -
QUANTIFYING UNCERTAINTIES IN THE PERFORMANCE PREDICTION OF EXISTING CONCRETE STRUCTURES USING AN EXTENDED DIRECT STIFFNESS METHOD APPROACH
(2023)Reinforced concrete structures are widely used in many industrialized countries. Currently, significant parts of the patrimony in these regions are reaching the end of their lifetime. As a result, the through-life analysis ... -
Quantitative 23Na-MRI: From Pre-Clinical to Clinical Practice
(2010)Quantitative 23Na-MRI (qNa-MRI) is a non-invasive technique which allows for measuring subtle changes in the Tissue Sodium Concentration (TSC) after ischaemic stroke. Although, an increase in TSC after stroke has been ... -
Quantitative accoustic analysis of inhaler sounds for the objective assessment of inhaler adherence in patients with chronic respiratory diseases
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)Asthma and chronic obstructive pulmonary disease (COPD) are two of the most prevalent chronic respiratory disorders. Over 800 million people suffer from these diseases and over four million people die annually. Although ... -
Quantitative assessment of perceptual, motor and cognitive function in Parkinson's disease and their contribution to freezing of gait
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2016) -
Quantitative modelling of human health risks arising from pesticide use in Irish agriculture
(2023)Pesticides have been identified as a growing concern due to the risk they pose to human health. Risk models can be used to predict pesticide concentrations in drinking water and analyse the associated health risks and hence ... -
Quantum dot energy relaxation mediated by plasmon emission in doped covalent semiconductor heterostructures
(American Physical Society, 2007)The interaction between interface plasmons within a doped substrate and quantum dot electrons or holes has been theoretically studied in double heterostructures based on covalent semiconductors. The interface plasmon modes, ... -
Quantum Dot Luminescent Solar Concentrator: Optimization of Concentration and Thickness
(2017)The absorption coefficient of a Luminescent Solar Concentrator (LSC) can non-linearly affect the total optical efficiency (η_opt) and solar concentration ratio (C_P) of the device. Absorption is determined by two critical ... -
Quantum effects in the Brownian motion of a particle in a double well potential in the overdamped limit.
(2009)Quantum effects in the noninertial Brownian motion of a particle in a double well potential are treated via a semiclassical Smoluchowski equation for the time evolution of the reduced Wigner distribution function in ... -
Quasiprobability density diffusion equations for the quantum Brownian motion in a potential
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2007)Wigner's [E. P. Wigner, Phys. Rev., 1932, 40, 749] representation of the density operator as a c-number quasiprobablity distribution in phase space allowing quantum mechanical averages involving the density matrix to be ... -
Radar, TV, and Cellular Bands: Which Spectrum Access Technique for Which Bands?
(2014)Opportunistic access has been considered by regu- lators for a number of different spectrum bands. In this paper, we discuss and qualitatively evaluate techniques used in the discovery of spectrum opportunities, also ... -
Radical plumbers and playpumps
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2011)This thesis analyses the PlayPump, a water pump powered by a children's roundabout, which is designed for use in the developing world. The PlayPump is analysed as an example of 'design for development', an area of current ... -
Radio Access Network and Spectrum Sharing in Future Mobile Networks
(2016)Future mobile networks will be characterized by wide-spread resource sharing, and a more nuanced view of what it means to offer a mobile service. The traditional view of a mobile network as a system that simply delivers ... -
Radio transmitter fingerprinting: A steady state frequency domain approach
(IEEE, 2008)We present a novel technique for radio transmitter identification based on frequency domain characteristics. Our technique detects the unique features imbued in a signal as it passes through a transmit chain. We are the ... -
Rail Passengers' Preferences for On-board Wi-fi Internet Access
(88th Annual Meeting of the Transportation Research Board, 2009) -
Rail passengers' preferences for onboard Wi-Fi internet access
(2009)This paper presents the results of a survey which was conducted on an Irish Rail service to ascertain how the value of travel time may change if individuals could partake in another activity while travelling. The survey ... -
Raman and Fourier transform infrared study of substitutional carbon incorporation in rapid thermal chemical vapor deposited Si 1-x-yGexCy on (1 0 0) Si
(2010)We report on a detailed study of the dependence of the vibrational modes in rapid thermal chemical vapor deposited Si1?x?yGexCy films on the substitutional carbon concentration. Si1?x?yGexCy films were investigated using ... -
Raman investigation of different polytypes in SiC thin films grown by solid-gas phase epitaxy on Si (111) and 6H-SiC substrates
(2010)Raman spectroscopy was applied to investigate a series of SiC films grown on Si and 6HSiC substrates by a new method of solid gas phase epitaxy. During the growth characteristic voids are formed in Si at the SiC/Si ...
