Accurate patient dosimetry in modern computed tomography systems
(NUI Galway, 2020-10-21)
The most common parameter used to estimate and minimise patient dose in computed tomography (CT) is the CT dose index (CTDI). The CTDI is the average absorbed dose from a series of contiguous irradiations along the long ...
The bile pigments and genetics of ballan wrasse morphotypes
(NUI Galway, 2020-12-10)
All fish have the pigment bilirubin in their blood which results from the breakdown of haemoglobin, however, some Labridae and other species also have an alternative pigment known as biliverdin which results in blue-green ...
Applying informal health reports and search queries for public health monitoring: An evaluation of characteristics, potentials, and requirements of online self-reporting, discussions, and search behaviour
(NUI Galway, 2021-01-13)
The introduction of digital data sources has positively impacted public health surveillance and has paved the way for novel approaches. Internet-based sources provide large volumes of data which can be analysed in near ...
An optical investigation into post compression aerodynamics in a dual opposed piston rapid compression machine
(NUI Galway, 2020-02-07)
Experimental chemical kineticists use rapid compression machines (RCMs) to verify models of global reactivity of fuels in as an ideal environment as possible, similar to those experienced in internal combustion engines. ...
Perspectives on driving mechanisms affecting intermediate water masses presence in the Rockall Trough
(NUI Galway, 2020-11)
The Rockall Trough (RT), a deep channel in the northeast North Atlantic (NA), hosts water masses of subpolar and subtropical origins. Large-scale atmospheric (North Atlantic oscillation, Eastern Atlantic pattern) and oceanic ...
Characterisation and testing of carbon fibre PEEK for linerless composite cryogenic storage tanks
(NUI Galway, 2020-05-07)
Cryogenic storage tanks, also known ’cryotanks’, are an important component of space launch vehicles. Cryotanks can form an integral part of the overall structure of the launch vehicle and also represent a significant ...
Experimental studies of simple hydrocarbons in a shock tube
(NUI Galway, 2020-09-24)
Chemical kinetic models are needed to simulate fuel chemistry in combustion devices and to aid
in the development of new designs to reduce harmful emissions and maximize combustor performance.
However, these models need ...
Query-aware adaptive windowing for spatiotemporal complex video event processing for internet of multimedia things
(NUI Galway, 2021-06-01)
With the evolution of the Internet of Things (IoT), there is an exponential rise in sensor devices that are deployed ubiquitously. Due to the extensive usage of IoT applications in smart cities, smart homes, self-driving ...
The impact of topology on diffusion processes in complex networks
(NUI Galway, 2019-10-18)
In this thesis we explore how the structure of a network impacts upon spreading behaviours on that network. We have created a dataset of 2,400 hyperbolic random geometric graphs, of increasing edge density from 0 to 1, and ...
A computational and experimental investigation of the in-vivo biomechanics of the human aorta
(NUI Galway, 2020-07-06)
The overall objective of this thesis is to provide a new understanding of the degree of biomechanical heterogeneity that exists along the human aorta, against the backdrop of clinical literature reporting that patient ...
