  • A Biomechanical Assessment of Direct and Inertial Head Loading in Rugby Union 

    TIERNEY, GREGORY JOHN (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)
    Rugby union is a territorial, dynamic and high-impact collision sport. Unfortunately, due to its physical and high impact nature, the incidence of concussion is high. There is mounting evidence that repeatedly sustaining ...
  • Biomechanical origins of osteoporosis 

    McNamara, Laoise Maria (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)
    The contention of this thesis is that a pathological change in bone tissue material properties during osteoporosis ahers the mechanical stimuli to bone remodelling cells and drives them to adapt the trabecular architecture ...
  • Biomechanics of Repair in Invertebrates 

    O'NEILL, MAEVE (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2019)
    Repair is a ubiquitous process in nature, and it is one of the many features of biological materials that humans are constantly attempting to recreate. Though the process of repair has been studied in mammals, very little ...
  • Biophysical Regulation of Stem Cell Osteogenic Lineage Commitment: A Role for the Cytoskeleton 

    STAVENSCHI, ELENA (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2019)
    Osteoporosis is a debilitating disease characterised by weakened bone architecture due to increased resorption activity of osteoclasts and diminished bone deposition by mesenchymal stem cell (MSC) derived osteoblasts. ...
  • Boundary element methods for the prediction of aircraft noise shielding in flight 

    Clancy, Cathal (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    Aircraft noise emissions may be significantly reduced by positioning the aeroengines above the wings or fuselage so as to utilize the shielding effect of the airframe. Computational tools are likely to play a key role in ...
  • Bubble growth dynamics in nucleate pool boiling with liquid subcooling effects 

    Mat Nawi, Muhad Rozi (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)
    Heat transfer in nucleate pool boiling has been characterized by very high dissipated heat fluxes whilst requiring low driving temperature differences. The rate of bubble growth and the subsequent bubble motion has a ...
  • Bubble growth dynamics including gravitational and electric field effects 

    Di Bari, Sergio (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    In the present work the hydrodynamics of adiabatic gas bubble growth from a submerged orifice is investigated with the view of elucidating the interdependence of the bubble shape and the pressure field during growth and ...
  • Bubble impingement and the mechanisms of heat transfer enhancement 

    Donoghue, David B (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)
    Fluid agitation and mixing ensuing from two phase flow has an important role to play within two phase flow heat exchangers, which are at the forefront of energy conversion. Within these environments, vapour bubbles may ...
  • Bubble-induced Marangoni convection 

    O'Shaughnessy, Séamus (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    Thermal Marangoni convection about a 1mm radius air bubble situated under a heated wall of constant temperature immersed in a silicone oil layer (Pr = 220) of constant depth 5mm was experimentally investigated using a flow ...
  • Cartilage extraceullular matrix-derived scaffolds for joint regeneration 

    Vazão de Almeida, Henrique Martiniano (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)
    The goal of this thesis was to address key limitations associated with autologous chondrocyte implantation (ACI) for articular cartilage regeneration, specifically the need for two hospital stays, cell culture and high ...
  • Case study of the Home Energy Saving Scheme : a multidisciplinary approach 

    Byrne, Amiee Jennifer (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)
    The EU has set itself the objective of achieving 20% primary energy savings by 2020. Because of the relatively recent move towards sustainability, there is a limited understanding of how effective related policies and ...
  • Characterisation and modelling of electro-pneumatic production systems 

    Harris, Paul (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    Compressed air is a widely employed energy source in modern manufacturing, accounting for a large percentage of plant electrical energy usage. However, the energy efficiency of such systems can be particularly low. Accurate ...
  • Characterisation and Reduction of Aircraft Landing Gear Noise 

    NERI, ELEONORA (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2017)
    Aircraft noise has become an important concern in aviation design as it has a negative impact on the health of people living in the vicinity of airports. The total noise of an aircraft is generated by the engines and by ...
  • Characterisation of an integrated telemetric temperature sensor for CFRP milling applications 

    Kerrigan, Kevin (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)
    The concept of a sensor designed to measure the behaviour of a machining process is a fundamental part of process monitoring and control. The perception of such a sensor is often underestimated when novel applications are ...
  • Characterisation of the performance of single point diamond dressers in abrasive processes 

    Murphy, Stuart (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)

  • Composite scaffold development and bioreactor culture for bone tissue engineering 

    Plunkett, Niamh (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2009)
    Bone tissue engineering involves seeding bone cells onto a scaffold, culturing this construct so that mineralisation occurs (by using signalling mechanisms such as growth factors or bioreactors) and then implanting it into ...
  • Composition and mechanical properties of osteoarthritic subchondral trabecular tibial bone 

    Gleeson, John Patrick (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)
    Osteoarthritis is a disease that has been characterised historically by the focal destruction of cartilaginous tissue and hence, is defined as such. However, recent investigations have brought this pathology into contention. ...
