    Valdes, Alejandro Lopez (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 

    Ní Ruaidhe, Máire (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 ...
  • Investigations into the mechanical properties of insect cuticle 

    Parle, Eoin E. (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)
    Insect cuticle is a composite material comprised of chitin fibres embedded in a protein matrix. It performs a wide variety of functions across class Insecta, and as such displays a wide bandwidth of material properties. ...
  • Iterative three-dimensional Helmholtz Equation solutions using the Wave Expansion Method 

    Gopalaswamy, Bharath (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)
    Modelling sound propagation often can present difficult challenges due to computational demands. In general, the direct solutions of the system equations arising from the full field discretization of many three-dimensional ...
  • Lean energy : a methodology to characterise and optimise energy consumption within manufacturing lines 

    Aughney, Niall J. (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2015)
    With an ongoing increase in industrial energy demand anticipated in Europe over the next twenty years, energy efficiency continues to be an important focus within industrial environments. As consumer products have become ...
  • Manipulation of decellularized porcine scaffolds for tissue engineering vascular grafts 

    Sheridan, William (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)
    The prevalence of vascular disease continues to increase worldwide, the treatment for which relies heavily on diseased vessel replacement. Tissue engineering vascular grafts potentially offers a new solution for addressing ...
  • Mechanical Assessment of the Risk of Atherosclerotic Plaque Rupture in Carotid Arteries with a Focus on Damage Accumulation 

    GHASEMI, MILAD (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2019)
    Carotid atherosclerotic plaque rupture is one of the leading causes of death. Growth and development of atherosclerotic plaque alters the geometry and mechanical environment of the healthy arterial tissue. Supra-physiological ...
  • Mechanical properties of diamond impregnated cobalt metal matrix 

    Dwan, James D. (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)
    Diamond Impregnated Metal Matrix (DIMM) composite materials are a class of materials used in cutting and drilling of stone and construction materials. This thesis examined the effects of diamond size and diamond concentration ...
  • Mechanics of the linea alba and suture-based wound closure 

    Cooney, Gerard M. (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)
    Over the past thirty years, there has been a dramatic change in the methodology of abdominal surgery. The introduction of digitalisation, miniaturisation, improved optics, novel imaging techniques and computerised information ...
  • Mechanobiology of tissue differentiation during osteochondral defect repair 

    Kelly, Daniel John (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)
    Differentiation can be thought of as a process by which cells and tissues undergo a change in phenotype toward a more specialized form or function. It is the contention of this thesis that tissue differentiation is in some ...
  • Mechanoregulation algorithms predicting peri-prosthetic bone adaptations 

    Scannell, Paul Timothy (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)
    Numerous mechanobiological algorithms have been developed in recent years to simulate biological processes such as bone remodelling and tissue differentiation. However, the implementation of such algorithms for the design ...
  • Mechanoregulation of bone formation : from embryogenesis to evolution 

    Nowlan, Niamh C. (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)
    In summary the author's thesis is that biophysical stimuli mechanoregulate ossification events through the action of mechanosensitive genes, where mechanoregulation is an ontogenetic process which has evolved. The author ...
  • Metal spinning, an incremental forming process 

    Quigley, Eamonn (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)
    Recent changes in product development processes have increased the demand for sheet metal parts manufactured in low volumes with the minimum investment in tooling. Spinning and a related process called 'incremental stretch ...
  • Microcracks and the fatigue behaviour of compact bone 

    O'Brien, Fergal Joseph (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2001)
    Microcracking in bone acts as a stimulus for bone remodelling, contributes to the loss of bone quality in osteoporosis and is thought to play a major role in both fragility and stress fractures. This study seeks to refine ...
  • Microphone array techniques for aeroacoustics 

    Jordan, Peter (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2001)
    The capacity for source localisation and measurement in aeroacoustics can be enhanced through the use of a microphone array. Although arrays have been used in a variety of applications, there are a number of problems ...
