Optimal Real-Time Predictive Control for Maximising the Power-Take-Off Efficiency of the WaveRAM Wave Energy Converter
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)The aim of this thesis is to develop a control strategy for optimising the power-take-off (PTO) efficiency of the newly developed WaveRAM (WRAM) wave energy converter. The three main research streams established to satisfy ... -
Incentivising Car-shedding Behaviour in the Greater Dublin Area
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)This doctoral research examines the behavioural response of commuters within the Greater Dublin Area (GDA), Ireland, to a range of policy incentives devised to encourage travellers to make greater usage of sustainable ... -
Resilience of Traffic Networks to Extreme Weather Events: Analysis and Assessment
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)The increment of extreme weather events is creating larger, and more frequent problems among infrastructure systems worldwide. In this thesis, the focus is on traffic networks by the analysis of a recent concept, the ... -
Active strategies with TMDs for control of wind turbine vibrations
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)This thesis investigates the use of active structural control techniques for the mitigation of the dynamic response of wind turbines with particular emphasis on reducing the in-plane (edgewise) vibrations in wind turbine ... -
The effect of prestress force magnitude and eccentricity on natural bending frequencies of prestressed concrete structures
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2016)The effect of prestress force magnitude on the natural bending frequencies of prestressed concrete structures is something widely debated in literature to date. It has major implications for the dynamic design and accurate ... -
The thermo-hygrometric environment in cathedrals in Ireland
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)Research was carried out into the often conflicting concepts of thermal comfort, conservation of artefacts and preservation of the 57 active cathedral buildings on the island of Ireland. Whilst the use to which these ... -
A review of structural failures in Ireland
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)Many technical papers have been written and presented to the structural engineering community in Ireland giving details of major projects successfully completed. These projects are on time and under budget. Far more ... -
Facade integrated concrete solar collectors
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)Concrete solar collectors are a type of solar thermal collector that are formed by embedding pipes within a layer of concrete that acts as the solar energy absorber. Concrete is a cheap, durable and abundant material that ... -
Development of predictive control strategies for building climate control
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2018)The rapid growth in energy usage and CO2 emissions has become a critical issue for the whole world. It is noteworthy that buildings are a major contributor to global primary energy consumption. Among building services, use ... -
The impact of domestic wastewater treatment system effluent on private water wells: an evaluation of contamination fingerprinting techniques
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2017)The absence of a public water supply network in many rural areas of Ireland means that approximately 162,000 households rely on private wells for their water provision. In many cases such rural areas are also not connected ... -
