Comparison of intermittently aerated sequencing batch reactors (IASBRs) and conventional sequencing batch reactors (cSBRs) in wastewater treatment
(2014-01-08)Increasingly stringent discharge standards, increased water usage, variations in wastewater characteristics and climate change have resulted in increased difficulty in achieving cost effective wastewater treatment. The ... -
A Comparison of the effects of Sensory-Integration Therapy and Behavioural Intervention on Challenging Behaviour and Academic Performance with Children with Autism
(2012-11)Autism spectrum disorder (ASD) is a neurodevelopmental disorder and presents as a complex and often puzzling category of conditions. Parents of children with ASD face a dilemma when selecting the most efficient and ... -
Completions of partial matrices
(2015-03-23)A partial matrix over a field is a matrix whose entries are either elements of the field or independent indeterminates. A completion of a partial matrix is any matrix that results from assigning a field element to each ... -
A complex systems approach to financial market analysis: Nonlinearity, regime shifts and early warning indicators
(2017-08-16)The history of financial markets over the past century points to the stylised fact that markets build up to a peak and then crash. Many of the standard methods for risk estimation and modelling of financial time series ... -
Comprehensive techno-econo-environmental modelling of renewable hydrogen supply chains
(NUI Galway, 2022-03-01)The research in this thesis has explored, investigated, and analysed renewable hydrogen supply chain opportunities and optimisation through techno-econo-environmental modelling. The modelling incorporates capital and ... -
Computation of cohomology operations for finite groups
(NUI Galway, 2018-08-31)The main result of this dissertation is the computation of all Steenrod squares on the Mod 2 cohomology of all groups of order dividing 32 and all but 58 groups of order 64; partial information on Steenrod square is ... -
Computational and experimental analysis of the mechanical performance of SLS generated polymer-ceramic bone scaffold materials
(2014-09-30)The load-bearing ability of orthopaedic scaffolds in critical-sized defects is of critical importance. 3D printing methods such as selective laser sintering (SLS) have great potential for the fabrication of patient-specific ... -
A computational and experimental investigation of the biomechanics of nickel-titanium stents for femoropopliteal applications
(NUI Galway, 2023-06-15)Self-expanding nickel-titanium stents are the current gold-standard in treating peripheral artery disease in the femoropopliteal artery. Despite this, failure rates in the femoropopliteal artery are much higher than ... -
A computational and experimental investigation of the dissection of arterial tissue
(NUI Galway, 2020-11-19)The overall objective of this thesis is to provide a new understanding of the mechanisms underlying arterial fracture, and to extend this understanding to the initiation and propagation of aortic dissection using a combination ... -
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 ... -
A computational and experimental investigation of tracheobronchial stent performance
(2017-05-25)Tracheobronchial stents are used to relieve blockages in the respiratory tree, typically caused by lung cancer. However, multiple complications can be associated with stents for this indication. In order to be able to ... -
Computational approaches to identify and explain sources of error in cancer somatic mutation data
(NUI Galway, 2024-04-18)Errors in the identification of somatic mutations in cancer samples can have critical implications in both research and clinical applications. Failure to detect potential variants of interest can lead to missed opportunities ... -
Computational design of glycomimetic inhibitors of Influenza A Adhesion
(2015-02-16)Many pathogens, such as avian influenza, Helicobacter pylori and Streptococcus pneumoniae, employ cell-surface glycans which terminate in Neu5AcAlpha(2-3)Gal as their adhesion partner.[1] As a result, a glycomimetic ... -
Computational development of a particle-In-cell computer code for the simulation of plasma Instabilities around rotation powered pulsars
(2014-09-03)This thesis reports on the design and development of DYMPHNA3D, a 3D particle-in-cell (PIC) plasma simulation code. It also focuses on the field of radio emission and the discovery of rotation powered neutron stars, ... -
Computational Homology of Cubical and Permutahedral Complexes
(2012-09-28)Homology is the study of connectivity and "holes" in spaces. The aim of this thesis is to introduce and develop a theory of permutahedral complexes for computations of homology of large data sets and to compare, using ... -
Computational homology of n-types
(2014-01-10)An n-type X is a CW-space with homotopy groups \pi_iX=0 for all i>n. Up to homotopy equivalence such a space can be specified algebraically by means of a simplicial group whose Moore complex is trivial in degrees >= n. For ... -
A computational investigation of the laser bonding of balloon catheters
(2015-09-28)The balloon catheters produced by Boston Scientific are manufactured using a laser bonding process. The behaviour of the materials during this laser welding process is not very well understood. In this work a computational ... -
A computational investigation of the long-term performance of bioabsorbable magnesium-based implants in orthopaedic fracture applications
(NUI Galway, 2023-06-20)Current orthopaedic fixation devices made from stainless steel and titanium can lead to a range of long-term complications that include bone reabsorption due to stress shielding, implant loosening and/or infection. ... -
