Transport disadvantage and car dependency in Rural Ireland
(2017)This paper explores the concepts of car dependency and deprivation and the correlation between them in areas of rural Ireland as a means of highlighting incidences of possible forced car ownership ... -
Encouraging sustainable commuting behaviour through smart policy provision
(2017)This paper explores the results of a stated preference (SP)experiment used to test the impact of policy incentives on commuting modal choice in the Greater Dublin Area (GDA). As a method of encouraging ... -
Particulate phosphorus and suspended solids losses from small agricultural catchments: links to stream and catchment characteristics.
(2019)Excessive phosphorus (P) inputs from agriculture are well established as a contributor to freshwater eutrophication. Decreasing these inputs is an important step in improving the ecological state of impaired waters. ... -
Hydropower Energy Recovery Systems: Development of Design Methodologies for Pumps As Turbines in Water Networks
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2020)Given the urgency of tackling the challenges offered by climate change and natural resource depletion, it is a priority to increase the sustainability of the water industry by reducing its energy demand and associated ... -
Analysis of Luminescent Solar Concentrator Performance Using a Ray Tracing Algorithm: Modelling, Optimization and Validation
(2017)In this paper, the behaviour of a LSC doped with Near-Infrared Quantum Dots (NIR-QD) in an epoxy host material is modelled by a ray tracing algorithm under different iteration numbers. It is shown that by increasing the ... -
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 ... -
Effects of Multiple Organic Dyes for Luminescent Down-Shifting Layers Application
(2017)High energy photons in the UV region are not efficiently used in solar cells and limit the overall efficiency of the cell. Luminescent Down-Shifting (LDS) layers can be used to convert the high energy photons to a lower ... -
Optimization and Photostability Studies of Luminescent Organic Dyes for Solar Devices
(2018)The overall efficiency of a solar cell is limited due to high energy photons within the UV region not being used efficiently. Luminescent Down-Shifting (LDS) layers are used to convert the high energy photons to a lower ... -
Improving the Mathematical Model for Luminescent Down-Shifting Layers by Investigating their Loss Mechanisms
(2017)A Luminescent Down-Shifting (LDS) layer is an optical approach to improve the solar cell’s optical response by using luminescent species doped in a polymer matrix material to form a thin layer to be deposited on top of the ... -
Individual Blade Pitch Control of Floating Offshore Wind Turbines for Load Mitigation and Power Regulation
(2021)This paper proposes a new strategy for individual blade pitch control to regulate power production while simultaneously alleviating structural loads on spar-type floating offshore wind turbines. Individual blade pitch ... -
Design of an active compliant liquid column damper by LQR and wavelet linear quadratic regulator control strategies
(2018)A new active tuned liquid column damper is developed for seismic vibration control of structures by employing the configuration of the compliant liquid column damper (CLCD). This control system is referred to as the active ... -
Conservation of Earthen Vernacular Architecture in Ireland Study of the Mechanical Properties and the Structural Behaviour of Cob
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2020)Cultural heritage is increasingly threatened not only by traditional causes of decay, but also by changing social, economic and environmental conditions. The deterioration or disappearance of any cultural item constitutes ... -
Large expert-curated database for benchmarking document similarity detection in biomedical literature search
(2019)Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that ... -
Transport Sector Impacts of a Border between Ireland and Northern Ireland after a Hard Brexit
(2019)More than half of British voters chose to leave the European Union (EU) leading to a series of negotiations between the United Kingdom and the EU. The withdrawal of the UK from the EU is widely referred to as Brexit. As ... -
An Evaluation of the Feasibility of Several Industrial Wastes and Natural Materials, as Precursors, for the Production of Alkali Activated Materials
(2019)In order to face current compelling environmental problems affecting the planet, the construction industry needs to adapt. It is widely acknowledged that there is a need for durable, high-performance, low-greenhouse gas ... -
Recycling plastic waste in cement composites for construction. Engineers Ireland Journal
(2019)Gurbir Kaur and Sara Pavía explore the possibility of raising the amount of recycled plastic (34%) by replacing sand with plastic waste in mortars and concretes, as this would not only reduce plastic incineration and ... -
An evaluation of the feasibility of industrial wastes and natural materials, as precursors, for the production of alkali activated materials (AAMs)
(2019)In order to face current compelling environmental problems affecting the planet, the construction industry needs to adapt. It is widely acknowledged that there is a need for durable, highperformance, low-greenhouse gas ... -
Limestone-filled, hydraulic-lime mortars for historic and traditional fabrics
(2019)Hydraulic lime (HL) mortars are considered compatible with historic fabrics and used in repairs. They consist of lime and clinkers (mainly belite). As belite hydrates slowly, some HLs develop strength for up to a year. ... -
Application off Hemp-Lime Renders to Improve Insulation of Walls
(2019)This paper measures the variation of thermal transmittance of solid brick walls triggered by the application of hemp-lime renders in an effort to enhance the insulating properties of buildings. Six renders with different ... -
Modelling diffuse groundwater recharge in Irish karst
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2020)Karstified carbonate aquifers are highly heterogeneous systems characterised by multiple component porosities and permeabilities. The different porosities are associated with different permeabilities commonly interpreted ...
