Biomimetic nano-biomaterials for bone repair and regeneration
(2017-02-24)Currently, over 1.7 billion people suffer from a musculoskeletal disorder; over 200 million operations take place annually; and in excess of 1 million new clinical cases are reported per year. Further, the annual healthcare ... -
Characterisation of rotationally moulded polymer liners for low permeability cryogenic applications in composite overwrapped pressure vessels
(2016-09-20)Composite overwrapped pressure vessels (COPVs) have become a critical component in satellite and space applications due to their ability to store highly permeating fuels at high pressures and under cryogenic conditions. ... -
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 ... -
Computational modelling of emissions from gas turbines: Ensuring experimental reliability and quantifying emissions uncertainty
(NUI Galway, 2019-02-18)Global environmental concerns and the increasing amount of power generated using gas turbines have led to the development of dry low emission (DLE) combustion systems to minimize the NOx and CO pollutants. Improvements in ... -
Computational modelling of thermofluid flashing in MSF desalination
(2017-08-21)Phase change inside a desalination flashing chamber arises from the surface evaporation with self-boiling of liquid brine flow due to a reduction of pressure. Flashing flow is the key to desalination of the feed water in ... -
Damage and permeability in linerless composite cryogenic tanks
(2015-09-29)Carbon fibre reinforced polymers (CFRP) are one of the prospective material families being investigated for use in the fuel tanks of future reusable launch vehicles (RLVs). The extreme cryogenic thermo-mechanical loading ... -
Design thinking capability model: A management framework to support design thinking implementation for product development
(NUI Galway, 2019-10-08)Design thinking is lauded to reduce cost and redesign work in the new product development process and shorten lead time to development. Because of that, researchers are investigating how to use using design thinking as ... -
Developing health and safety guidance for geodetic engineering surveyors
(NUI Galway, 2018-12-21)Geodetic engineering surveyors are integral to the entire construction process and work in a sector that is considered occupationally hazardous. The aim of this research was to determine the extent of health and safety ... -
Development of correlated and computational methods for predicting premixed turbulent flame speed
(NUI Galway, 2018-10-02)Turbulent flame speed is an important property within turbulent flames and an invaluable parameter for gas turbine combustor design. A major issue however is the difficulty in accurately predicting turbulent flame speed ... -
Entrepreneurial self-efficacy (ESE): a business model approach
(2016-04-07)Researchers of entrepreneurship lack a general, yet distinct, conceptual framework that both describes how entrepreneurial action occurs and predicts who does it. Some scholars have noted that the emerging concept of ... -
An experimental and computational investigation of the high temperature behaviour of MarBN steel with application to effects of manufacturing
(NUI Galway, 2018-10-30)The key step for next generation power plants is the development of advanced materials capable of achieving high flexibility and efficiency at increased steam temperatures and pressures. Such operating conditions will cause ... -
Experimental and numerical characterisation of materials for biomass co-firing
(2017-02-23)As Europe continues to decarbonize its electricity generation capacity, operators of thermal power plants face challenges to which they must adapt including increasingly transient operation and co-firing with biomass. This ... -
Experimental characterisation and computational constitutive modelling of high temperature degradation in 9Cr steels including microstructural effects
(2016-04-20)The transition from base-load to intermittent power plant operation has led to the requirement for increased knowledge and more accurate prediction of the effects of flexible loading on plant components. This thesis is ... -
Experimental development and modelling of a novel auxiliary power unit for heavy trucks
(2017-09-26)This thesis identifies the key technical requirements for a heavy truck auxiliary power unit (APU) and explores a potential alternative technology for use in a next-generation APU that could eliminate key problems related ... -
Factors that facilitate regulatory approval for drug/device combination products in the European Union and United States of America: a mixed method study of industry views
(2015-09-30)Drug/device combination products play a vital role in diagnosis and treatment of a wide range of disorders, including chronic disorders such as heart disease, cancer, respiratory disease, and diabetes. Doctors consider ... -
High-resolution measurements of leakage flow through bileaflet mechanical heart valve hinges
(2017-02-24)To restore proper function of the heart, diseased valves require repair or replacement. Mechanical heart valves are one of the treatments available. Despite their superior durability in comparison with biological prostheses, ... -
