Identification of rupture locations in patient-specific abdominal aortic aneurysms using experimental and computational techniques

Doyle, Barry J.; Cloonan, Aidan J.; Walsh, Michael T.; Vorp, David A.; McGloughlin, Timothy M. (Elsevier Science, 2010)

In the event of abdominal aortic aneurysm (AAA) rupture, the outcome is often death. This paper aims to experimentally identify the rupture locations of in vitro AAA models and validate these rupture sites using finite ...
Immersion condensation on oil-infused heterogeneous surfaces for enhanced heat transfer

Xiao, Rong; Milikovic, Nenad; Enright, Ryan; Wang, Evelyn N. (Nature Publishing Group, 2013)

Enhancing condensation heat transfer is important for broad applications from power generation to water harvesting systems. Significant efforts have focused on easy removal of the condensate, yet the other desired properties ...
Improved assessment and treatment of abdominal aortic aneurysms: the use of 3D reconstructions as a surgical guidance tool in endovascular repair.

Doyle, Barry J.; Grace, Pierce A.; Kavanagh, Eamon G; Burke, Paul E.; Wallis, Fintan; Walsh, Michael T.; McGloughlin, Timothy M. (Springer, 2009)

BACKGROUND: Endovascular repair is fast becoming the treatment of choice for abdominal aortic aneurysms in anatomically suitable patients. 3D reconstructions not only aid conventional 2D measurements but also allow further ...
Improving the performance of out-of-autoclave composite laminates using an interlaminar toughening technique

Nash, Niamh (University of Limerick, 2016)

The increasing demand for composite materials has meant that there is a need to develop out-of-autoclave (OOA) manufacturing processes that can produce cost-effective high-quality components. Autoclaves cannot meet the ...
In-situ surface and interface study of atomic oxygen modified carbon containing porous low-κ dielectric films for barrier layer applications

Bogan, J.; Lundy, Ross; McCoy, A.P.; O'Connor, R.; Byrne, C.; Walsh, L.; Casey, P.; Hughes, G. (AIP Publishing, 2016)

The surface treatment of ultralow-k dielectric layers by exposure to atomic oxygen is presented as a potential mechanism to modify the chemical composition of the dielectric surface to facilitate copper diffusion barrier ...
Indian and Chinese aviation industry: the EASA framework option

Kourousis, Kyriakos I.; Comer, Anthony (Emerald Publishing Group Limited, 2018)

Purpose This viewpoint aims to increase the awareness on the demand faced by the technical sector of the Indian and Chinese aviation industry and how this can be met by the adoption of the European Aviation Safety Agency ...
The influence of composition and location on the toughness of human atherosclerotic femoral plaque tissue

Cunnane, Eoghan M.; Barrett, Hilary E.; Kavanagh, E.G; Mongrain, R; Walsh, Michael T. (Elsevier, 2016)

The toughness of femoral atherosclerotic tissue is of pivotal importance to understanding the mechanism of luminal expansion during cutting balloon angioplasty (CBA) in the peripheral vessels. Furthermore, the ability ...
The influence of surfactants on capillary driven flow in open hydrophobic microchannels towards chip-based fluorescent detection of HSV

O'Leary, Fiachra (University of Limerick, 2011)

Herpes Simplex Virus (HSV) is widespread among the human population. HSV infection can have subtle symptoms and often go undiagnosed. There are two types of HSV infections. HSV type 1 (HSV-1) is associated with orofacial ...
Interface characterization of thermoplastic skin-stiffener composite manufactured using laser-assisted tape placement

Bandaru, Aswani Kumar; Clancy, Gearóid J.; Peeters, Daniël; O'Higgins, Ronan M.; Weaver, Paul M. (American Institute of Aeronautics and Astronautics: AIAA, 2018)

Laser-Assisted Tape Placement (LATP) is an advanced manufacturing process which has gained the attention of the aerospace industry. Composite laminates manufactured using this technique have to be characterized effectively ...
Interim report on development of progressive failure model for composite bolted joints based on stiffness reduction scheme

McCarthy, Michael A.; Padhi, G.S; McCarthy, Conor T. (University of Limerick, 2003)

The project “A Study of Damage Initiation and Growth in Composite Bolted Joints” is funded under the Basic Research Grants Scheme 2002, jointly administered by Enterprise Ireland and the Irish Research Council for Science, ...
Intramural stresses at the distal graft/artery junction following femoral artery bypass surgery

O'Donnell, Michael R. (University of Limerick, 2010)

Intimal hyperplasia development in the downstream anastomosis of a peripheral bypass grafts has been the subject of much investigation due to its site specific focal development at specific sites within the junction. ...
Introduction

Young, Trevor M. (Wiley and Sons Ltd, 2017)

Performance of the Jet Transport Airplane: Analysis Methods, Flight Operations, and Regulations presents a detailed and comprehensive treatment of performance analysis techniques for jet transport airplanes. Uniquely, ...
An investigation into the behaviour of thick pin-loaded joints under a bearing load

Stritch, Thomas Patrick (University of Limerick, 2014)

The behaviour of a thick pin-loaded lug was investigated when subjected to a bearing load using the embedded strain gauge technique and finite element analysis. The embedded strain gauge technique was extended to the ...
An investigation into the effects of mechanical loading patterns from everyday activities on long term stability after cementless hip replacement surgery.

O'Reilly, David S. (University of Limerick, 2011)

The number of Total Hip Replacement (THR) surgeries carried out per year is increasing year on year as people live longer and partake in a more active lifestyle. Other factors such as obesity and weight problems are also ...
Investigation into three dimensional ultrasound for generating vascular reconstructions suitable for diagnostic technique development

Gaughan, Sarah (University of Limerick, 2014)

A three dimensional ultrasound (3DUS) system was developed with the aim of generating three dimensional (3D) vascular reconstructions. The system was required to be compatible with both a linear and a curvilinear transducer. ...
Investigation of first generation biofuels in diesel engines.

Madden, Orla (University of Limerick, 2011)

In an AC1W IDI Lister Petter diesel engine, ignition delay reduced exponentially with an increase in engine speed for hempseed oil (HSO), camelina seed oil (CSO) and rapeseed oil (RSO). The polyunsaturated fuels HSO ...
Investigation of microscale damage processes near adhesive-composite interfaces

O'Dwyer, Donal John (University of Limerick, 2013)

The increasing use of composite materials in the aerospace industry has necessitated significant advancements in the prediction of damage in composite structures. Adhesive joints have recently become more widespread, as ...
An investigation of the fabrication and characterisation of nanocomposite thermal interface materials

Munari, Alessio (University of Limerick, 2011)

Contemporary electronic devices such as microprocessors feature high component-level heat-fluxes and tight temperature constraints. Thermal interface materials (TIMs) are a critical element in the path for heat transfer ...
Lies, damned lies and quality management systems: a pilot case study

Brooks, Tara; Spillane, John P. (ARCOM: Association of Researchers in Construction Management, 2017)

An externally accredited ISO 9001 Quality Management System is a prerequisite for tendering for many public-sector projects, leaving Small to Medium Enterprises little choice but to implement such a system. A link between ...
Measurement of strain induced responses at femoral artery bypass graft junctions
