Acoustic radiation force impulse imaging for aneurysms

Tierney, Áine P.; Dumont, Douglas; Callanan, Anthony; McGloughlin, Timothy M. (IEEE Computer Society, 2009)

A method for reliable, noninvasive estimation of Abdominal Aortic Aneurysms (AAA) wall mechanics may be a useful clinical tool for rupture prediction. An in vitro AAA model was developed from an excised porcine aorta, ...
Aircraft crown compartment thermal management: the influence of internal heat dissipating elements

Butler, Colin (University of Limerick, 2013)

The content of this thesis describes the interaction of internal heat dissipating elements with their heated enclosure with the applied case of a crown compartment in a single aisle commercial aircraft. The crown compartment ...
The analysis of lactate-pyruvate levels and growth proliferation rates of endothelial cells on urinary bladder matrix: a potential vascular graft

Callanan, Anthony; Guihen, Elizabeth; Walsh, Michael T.; O'Connor, William T.; McGloughlin, Timothy M. (2010)

Arterial diseases are a common cause of death in the western world. The development of arterial substitute materials for the improved treatment of cardiovascular diseases is vital. One such material is urinary bladder ...
Anticipating the need for new skills for the future aerospace and aviation professionals

Lappas, Ilias; Kourousis, Kyriakos (Institute of Aeronautics and Space, 2016)

This study aims to translate needed future skills to the university classroom for the aerospace and aviation industry personnel, given the fast-paced change taking place in both the industry and the education sectors. A ...
Augmentation cystoplasty and extracellular matrix scaffolds: an ex vivo comparative study with autogenous detubularised Ileum

Davis, Niall Francis; Mooney, Rory; Callanan, Anthony; Flood, Hugh D.; McGloughlin, Timothy M. (Public Library of Science, 2011)

Background: Augmentation cystoplasty (AC) with autogenous ileum remains the current gold standard surgical treatment for many patients with end-stage bladder disease. However, the presence of mucus-secreting epithelium ...
Biomechanical and computational investigation of the hip protector design and function

Madrecka, Aleksandra (University of Limerick, 2012)

and related hip fracture in the elderly population are a serious problem in health care. It is widely documented that prevention of hip fracture has the potential to improve the quality of life and substantially decrease ...
BOJCAS: Bolted joints in composite aircraft structures

McCarthy, Michael A (University of Limerick, 2003)

The objective of BOJCAS was to develop advanced design methods for bolted joints in composite aircraft structures. This is a critical technology supporting the introduction of composites into the primary structure of ...
Cell-seeded decellularised extracellular matrices as an advanced approach for tissue engineering

Piterina, Anna Valentinova; Davis, Laura M.; Meaney, Claire L.; Cloonan, Aidan J.; Walsh, Michael T.; McGloughlin, Timothy M. (2009)

Development and optimisation of therapeutic applications using biological scaffolds composed of naturally occurring extracellular matrix (ECM) have received significant attention in the field of tissue engineering. ...
Characterising human atherosclerotic carotid plaque tissue composition and morphology using combined spectroscopic and imaging modalities

Barrett, Hilary E; Mulvihill, John J; Cunnane, Eoghan M; Walsh, Michael T. (BioMed Central, 2015)

Calcification is a marked pathological component in carotid artery plaque. Studies have suggested that calcification may induce regions of high stress concentrations therefore increasing the potential for rupture. However, ...
The characterization of obstructed laminar channel flows for local heat transfer enhancement in microfluidic cooling applications

Waddell, Alistair Martin (University of Limerick, 2015)

Some of the largest heat fluxes that can be found in contemporary engineering applications (O ∼ 10^3 W/cm2) are generated by laser-bar arrays within Photonics Integrated Circuits (PICs) – the backbone of optical telecommunication ...
Comparing the endothelialisation of extracellular matrix bioscaffolds with coated synthetic vascular graft materials

Coakley, Daniel Nicholas Martin; Shaikh, F.M; O'Sullivan, K; Kavanagh, Eamonn G; Grace, P.A; Walsh, S.R; McGloughlin, Timothy M. (Elsevier, 2016)

Introduction Existing synthetic vascular grafts have unacceptably high failure rates when replacing small diameter infrapopliteal vessels [1]. The lack of a confluent endothelial lining is repeatedly cited as the most ...
A comparison of modelling techniques for computing wall stress in abdominal aortic aneurysms

Doyle, Barry J.; Callanan, Anthony; McGloughlin, Timothy M. (BioMed Central, 2007)

BACKGROUND: Aneurysms, in particular abdominal aortic aneurysms (AAA), form a significant portion of cardiovascular related deaths. There is much debate as to the most suitable tool for rupture prediction and interventional ...
Comparison of open hole tension characteristics of high strength glass and carbon fibre-reinforced composite materials

O'Higgins, Ronan M; McCarthy, Michael A; McCarthy, Conor T (Elsevier, 2008)

An experimental study was carried out to determine the open hole tension (OHT) characteristics of carbon fibre-reinforced plastic (CFRP) and high strength S2-glass fibre-reinforced plastic (GFRP). Tests to failure and ...
Computational modelling of energy absorption characteristics of epoxy/CNT nanocomposites

Weidt, David (University of Limerick, 2014)

Epoxy-based composite laminates frequently behave as brittle materials under various types of loading, from quasi-static to impact, as they cannot absorb/dissipate enough energy. Matrix cracks develop due to the brittle ...
Cyclic plasticity model with multiplicative backstress decomposition

Kourousis, Kyriakos; Saridis, G.J; Dafalias, Y.F (Transworld Research Network, 2007)

The challenge of developing a generalized mathematical pattern to describe the plastic behaviour of metals, lead researchers to propose various constitutive models, especially in the field of cyclic plasticity, where ...
Damage modelling of fibre reinforced polymer matrix composite open hole tension specimens using the Ladevèze damage model in Pam-CRASH

O'Higgins, Ronan M; McCarthy, Michael A (2005)

The goal of this project was to accurately predict the ultimate failure strengths of fibre reinforced polymer matrix composite open hole tension specimens using the Ladevèze continuum mechanics damage model, currently ...
Design and characterisation of a micro-flow cytometer with 3D hydrodynamic focusing

Chiavaroli, Stefano (University of Limerick, 2011)

Recent advances in micro fabrication technology have resulted in proliferation of microscale mechanical devices, most of which are applied in the biomedical field and clinical diagnostics. One of the most promising ...
ECM-based materials in cardiovascular applications: inherent healing potential and augmentation of native regenerative processes

Piterina, Anna Valentinova; Cloonan, Aidan J.; Meaney, Claire L.; Davis, Laura M.; Callanan, Anthony; Walsh, Michael T.; McGloughlin, Timothy M. (MDPIAG, 2009)
