Factors that affect mass transport from drug eluting stents into the artery wall

O'Connell, Barry M; McGloughlin, Timothy M.; Walsh, Michael T. (BioMed Central, 2010)

Coronary artery disease can be treated by implanting a stent into the blocked region of an artery, thus enabling blood perfusion to distal vessels. Minimally invasive procedures of this nature often result in damage to ...
Failure analysis and stress simulation in small multichip BGAs

Moore, Thomas D.; Jarvis, John L. (IEEE Computer Society, 2001)

This paper examines one of the common modes of structural failure in multichip ball grid arrays (BGAs), determines its locations within the package structure, relates it to the stresses generated in the reliability tests ...
FE modelling of countersunk composite joints for next-generation aircraft

Egan, Brian; McCarthy, Conor T.; McCarthy, Michael A. (2013)
Final report on development of the progressive failure model for composite bolted joints based on stiffness reduction scheme

Padhi, G.S (University of Limerick, 2004)

In D1.2 [1] an interim report was presented on the development of a computational model for the prediction of the initiation and growth of damage in composite bolted joints based on the stiffness reduction scheme. The ...
Finite element analysis of catastrophic failure of dynamically-loaded countersunk composite fuselage joints

Egan, Brian; McCarthy, Michael A.; Frizzell, R.M.; McCarthy, Conor T. (Elsevier, 2015)

Accurate models of dynamic structural failure are important for crashworthiness studies. To date, catastrophic failure of dynamically-loaded composite bolted joints has been studied using global or stacked shell element ...
A finite element analysis rupture index (FEARI) as an additional tool for abdominal aortic aneurysm rupture prediction

McGloughlin, Timothy M.; Doyle, Barry J.; Callanan, Anthony; Walsh, Michael T.; Grace, Pierce A. (Bentham Science Publishers, 2009)

Currently, abdominal aortic aneurysms (AAAs), which are a permanent dilation of the aorta, are treated surgically when the maximum transverse diameter surpasses 5.5cm. AAA rupture occurs when the locally acting wall stress ...
Finite element investigation of the human mandible bone: examination of bone fracture, plate fixation and increasing degrees of atrophy

Kavanagh, Edel; Kearns, Gerard J (Univesity of Limerick, 2012)

The mandible is the largest of the human facial bones. It is located inferiorly at the base of the skull. Fracture of the mandible bone is a frequent event due to the positioning of the bone on the face. These fractures ...
Finite element modelling and high speed testing of countersunk composite aircraft joints

Egan, Brian (University of Limerick, 2014)

Bolted joints feature extensively in composite aircraft structures, facilitating disassembly for maintenance while offering a cost effective joining method. However, inadequate tools for predicting failure of composite ...
Fluid-structure interaction of a patient-specific abdominal aortic aneurysm treated with an endovascular stent-graft

Moloney David S; Callanan, Anthony; Kavanagh, Eamon G.; Walsh, Michael T.; McGloughlin, Timothy M. (BioMed Central, 2009)

Background: Abdominal aortic aneurysms (AAA) are local dilatations of the infrarenal aorta. If left untreated they may rupture and lead to death. One form of treatment is the minimally invasive insertion of a stent-graft ...
Formation of reworkable nanocomposite adhesives by dielectric heating of epoxy resin embedded Fe3O4 hollow spheres

Zhao, Bin; Hardiman, Mark; Ryan, Kevin M.; O'Reilly, Emmet J.; McCarthy, Conor T. (Royal Society of Chemistry, 2016)

Epoxy resin (ER) thermosetting adhesives provide highly cross-linked 3-dimensional structures leading to highly stable and strong mechanical/physical performance in a wide range of bonding applications. However, such ...
Fracture strength of carbon nanotubes with interwall sp3 bonding and intrawall vacancy defects

Byrne, E.M.; McCarthy, Michael A.; Xia, Z.; Curtin, W.A. (2009)

In the discipline of nanomaterials, the outstanding mechanical properties of nanoscale fibres and tubes (carbon nanotubes or CNTs) make them highly attractive as potential reinforcing constituents in polymer, ceramic or ...
From crisis to opportunity: turnaround strategies of large Irish construction contractors during the period 2007-2015

Tansey, Paul; Spillane, John P. (ARCOM: Association of Researchers in Construction Management, 2016)

The sudden change in environmental munificence level in the construction sector during the period 2007 – 2015 provides a natural experiment to investigate strategic and operating actions of firms, particularly during an ...
Generating rich trip data using smartphone applications to facilitate feasibility studies for bicycle sharing schemes

O'Regan, Leo; Cosgrove, Tom; Higgins, Ross (Irish Transport Research Network, 2015)

Limerick was designated as Ireland’s National Smarter Travel demonstration area in 2012. Limerick Smarter Travel, which aims to promote sustainable travel in the City and suburbs, is a partnership between the Limerick ...
Government influence on the construction industry during the economic recession 2007 – 2013

Tansey, Paul; Spillane, John P. (ARCOM: Association of Researchers in construction Management, 2014)

Due to the high degree of international and economic integration across the globe, the 2007 global financial crisis quickly spread, causing recessions and widespread credit restrictions in advanced nations. During recessions, ...
Group peer review of engineering lecturing

Cole, Reena; Fowler, E; McCarthy, Conor T.; Newport, David; Walsh, Michael T. (2011)
Guidelines for developing efficient thermal conduction and storage models within building energy simulations

Hillary, Jason; Walsh, Ed J.; Shah, Amip; Zhou, Rongliang; Walsh, Pat A. (Elsevier, 2017)

Improving building energy efficiency is of paramount importance due to the large proportion of energy consumed by thermal operations. Consequently, simulating a building's environment has gained popularity for assessing ...
The heterogeneous crystallization of a novel solvate of clozapine base in the presence of excipients

Verma, Vivek; Bannigan, Pauric; Lusi, Matteo; Crowley, Clare M.; Hudson, Sarah; Hodnett, Benjamin K.; Davern, Peter (Royal Society of Chemistry, 2018)

A new methanol solvate of clozapine base (CPB) has been identified. It exhibits different molecular arrangements and bonding environments at low and room temperatures, while still maintaining the same PXRD pattern throughout. ...
Higher education aviation programs in Greece: a missed opportunity or a challenge to meet?

Malagas, Konstantinos; Fragoudaki, Alexandra; Kourousis, Kyriakos I.; Nikitakos, Nikitas (Instituto de Aeronautica e Espaco (I A E), 2017)

The air transport industry in Greece has been experiencing a significant growth. However, higher education has missed so far this export opportunity. Public universities and technological educational institutes have very ...
Highly efficient numerical analysis of load distribution in composite bolted joints

Gray, Patrick Joseph (University of Limerick, 2011)
