A Bridgman Furnace Front Tracking Model
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2015)The Bridgman furnace is widely used in industry and research, mainly because it provides a means to directionally solidify materials in a controlled manner, so that the resulting microstructure, and hence material properties, ... -
Active speaker localisation and tracking using audio and video
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2010) -
An investigation into the effects of the density of on-site wastewater treatment systems on Irish aquifer
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Groundwater is an important resource in Ireland and given that over 25% of all water supplies are currently provided directly from groundwater abstractions, it is critical to protect this resource from contamination. Most ... -
An investigation of the influence of daily activities and location on personal exposure to air pollution in Dublin : measurement, analysis, modelling and application
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The research in this study was carried out to quantify real-time personal exposure to PM10 in a large number of individuals residing in the Dublin area. This was carried out in order to highlight activities and locations ... -
Automatic recognition of ageing speakers

Bike-ology: Evaluating inter-urban and rural cycling infrastructure
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2014)This thesis reports the outcomes of a study conducted to ascertain the benefits derived from different cycling infrastructure, in rural and interurban locations, for different trip purposes. -
Capping transport emissions: A welfare analysis of a personal carbon trading scheme
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)This thesis presents the findings of a study to determine the welfare effects of a personal carbon trading scheme (PCTS) for the transport sector. A PCTS sets a limit on carbon and allocates free permits to all participants. ... -
Cooling by high speed air jet in orthogonal machining operations
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)Changing environmental awareness has led manufacturing industry to give critical consideration to the use of conventional coolants and traditional cooling techniques in machining processes. Current research shows that ... -
Design and analysis of concentrically braced steel frames under seismic loading
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The lateral resistance of many steel framed structures is provided by diagonal brace members and their connections to the frame. Although concentrically braced frames (CBFs) are common throughout international design ... -
EHD augmentation of convective boiling within a transparent heat exchange
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)This work investigated the influence of electrohydrodynamic forces on the two-phase flow patterns of HFE7000 refrigerant under convective boiling conditions. A flow loop was constructed which featured two novel transparent ... -
Experimental investigations in turbomachinery noise-source identification
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)The exact contribution of each of the various core-noise sources within modern turboshaft engines to the noise radiated from the engine exhaust and into the surrounding environment is poorly understood. The objective of ... -
Front-end analogue filter design for diagnostic electrocardiographic equipment
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2013)This thesis addresses the design of an analogue front-end filter for portable electrocardiographic equipment. The task of the filter is to eliminate as much out-of-band noise and interference as possible before the ... -
Hydropower energy recovery form the water supply network : feasibility, risk analysis, optimisation and implementation
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)The provision of clean and reliable water supply is highly energy intensive. Recent research has focused on the development and application of energy and hydraulic efficiency measures to streamline water usage and improve ... -
Justification for the Implementation of Citywide GPS System
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2003)Over the past few years, there has been an increase in the use of telematics in Demand Responsive Transport like taxis, so as to maximize the ever-increasing demand. To provide better customer service in the competitive ... -
Micromechanical modelling of normal, drug treated and osteoporotic bone using scanning acoustic microsopy and finite element analysis
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Ultrasonic methods were exclusively used to image cortical bone at high resolutions. A scanning acoustic microscope was used at a frequency of 150 MHz giving a resolution of 20μm. Images were taken of ovine bone samples ... -
