  • The development of a vibro-acoustic model of the human ear 

    McAvoy, G. J. (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 1995)
  • Time domain calculation of noise generated by a propeller in a flow 

    Carley, Michael (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 1997)
    In this thesis, the problem of calcultaing the noise from an acoustically subsonic aircraft propeller is approached using a "moving medium" method. An established theory of noise generation by rigid bodies in motion is ...
  • Identification of a non-linear model for fluidelastic instability in a normal triangular tube array 

    Meskell, Craig (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 1999)
  • Modeling of the forces in grinding from grinding wheel topography 

    Badger, Jeffrey Kavanaugh (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2000)
    As the world becomes more industrialized and competition for fast, high quality production increases, the need to obtain faster manufacturing processes, while simultaneously increasing product quality, becomes increasingly ...
  • Simulation of tissue differentation during fracture healing 

    Lacroix, Damien (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2001)
    Fracture healing is a complex biological process during which, repair of the damaged tissues occurs so efficiently that the initial strength and anatomy of the bone are restored. Mechanical loading is believed to greatly ...
  • 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 ...
  • Aspects of the fatigue behaviour of acrylic bone cement 

    Murphy, Bruce Philip (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2002)
    Polymethylmethacrylate bone cement is used to fixate many orthopaedic implants. However, it is a brittle material, prone to damage accumulation leading to cement cracking and prosthesis loosening. The damage accumulation ...
  • The fatigue behaviour of three-dimensional stress concentrations 

    Bellett, Daniel (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)
    The fatigue behaviour of complex three-dimensional notched components is a subject of great practical interest to industrial engineers. Unfortunately, the analysis of this type of feature presents problems for most assessment ...
  • Three-dimensional vortex particle-in-cell technique 

    Cox, Damien (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)
  • The cellular transducer in damage-stimulated bone remodelling 

    Hazenberg, Jan Geert (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)
    People with osteoporosis, osteopenia or weight baring joint replacement, due to an altered loading configuration, are more susceptible to microdamage accumulation than normal human beings as are athletes who undertake ...
  • An investigation into the influence of cardiovascular stent design on the development of restenosis using the finite element method 

    Lally, Caitriona (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)
    Finite element models, which can determine the degree of vascular injury caused to a vessel by a stent and hence ascertain the propensity of that stent design to cause in¬stent restenosis, would be a valuable tool for both ...
  • The relationship between blood perfusion and thermal measurements at the skin surface 

    Nicholson, Christopher P. B. (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2006)
    Blood perfusion is defined as the volumetric flow rate of blood through a given volume of tissue. Blood perfusion measurements are an important clinical indicator for many medical conditions but to date there is no cost ...
  • Multivariate statistical methods for fault detection and classification 

    Southern, William Richard (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2006)
  • 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 ...
  • 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 ...
  • 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. ...
  • Passive mechanical properties of skeletal muscle in compression 

    Van Loocke, Mélanie (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)
    The compressive properties of skeletal muscle are of prime interest in applications where muscle tissue is submitted to compressive loads; e.g., to improve the design of protective equipment for vehicular occupants, to ...
  • A forward advancing wave expansion method for numerical solution of large-scale sound propagation problems 

    Rolla, Leandro Miguel Barrera (Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)
    The study of atmospheric somid propagation has become an important subject since noise polhition problems emerged as a highly relevant matter in several areas such as sociology, economics, regulations and standards. Modelling ...
