This thesis contains parametric analyses of the hydrodynamics and heat transfer of a laminar ... -
Hypothesis testing of glenoid component innovation in total shoulder arthroplasty
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)A glenoid component with reliable long-term performance does not exist for total shoulder arthroplasty. Poor glenoid component durability may be explained by the huge variability that exists at the shoulder joint ... -
Identification and Measurement of Variables Affecting Component Lifetime: A Case Study of Polymer Degradation in the Biopharmaceutical Industry
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)Modern maintenance methods are dependent upon understanding and monitoring component degradation; however, many industrial situations exist where monitoring is impossible, and component degradation mechanisms are not well ... -
Identification of a non-linear model for fluidelastic instability in a normal triangular tube array
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 1999) -
Influence of Mechanical Environment on Limbal and Corneal Epithelial Cells
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2021)Corneal blindness is the 4th leading cause of blindness and the most transplanted tissue worldwide. Severe donor shortages and immune rejection has led to research into alternative therapies for corneal transplantation. ... -
Integrating non-viral gene therapy and 3D bioprinting for bone, cartilage and osteochondral tissue engineering
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)The repair of osteochondral defects, affecting both the articular cartilage and the underlying subchondral bone, is key for the effective recovery of joint homeostasis and the prevention of further cartilage degeneration ... -
Interaction between fluidelastic instability and acoustic resonance
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2008) -
Investigating of dual-jet air curtains for a landing gear noise reduction technology
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2017)As the popularity of air travel increases, noise that it causes to the communities around airports has become a major concern to the aeronautical industry. World leading economic entities, such as EU and US, have made ... -
Investigating the applicability of single-channel electroencephalography in cochlear implant patients
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2017)Hearing impairment affects over 5% of the population worldwide. Namely, about a quarter of a million adults in Ireland are estimated to have permanent hearing impairment due mainly to ageing and/or noise exposure. Cochlear ... -
Investigating the load, friction and sealability characteristics of graphite valve packings
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2005)It is widely accepted that valve stem leakage accounts for the majority of fugitive emissions from petrochemical and chemical sites often accounting for over 50% of fugitive emissions from these sites. The most common valve ... -
Investigation into the collagen fibre-mediated fatigue mechanics of bovine pericardium for use in bioprosthetic heart valves
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2021)Bioprosthetic heart valve replacements have long been associated with inadequate durability in vivo, owing primarily to mechanical damage and calcification of the glutaraldehyde-fixed bovine pericardial leaflets (GLBP). ... -
