Mechanoregulated tissue organisation during skeletal repair : a computational study
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)Articular cartilage is a highly specialised bearing material that provides low friction, wear resistant contact between the ends of articulating bones in diarthrodial joints. In order to function in this mechanically ... -
Computational investigation into the mechanoregulation of osteoporosis
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2009)Trabecular bone remodelling involves the continual resorption and formation of bone along the surface of a strut. Experimental studies have shown that mechanical stimuli, such as strain and damage, initiate and regulate ... -
Analysis of the elastic and inelastic behaviour of healthy and diseased arterial tissue
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)Mechanical factors play a key role in determining the success of clinical procedures such as balloon angioplasty and stenting that aim to increase lumen size in atherosclerotic lesions. Finite element modelling is commonly ... -
Characterisation of an integrated telemetric temperature sensor for CFRP milling applications
(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 ... -
An investigation of structure-function relations in articular cartilage during skeletal maturation
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)The over-riding objective of this thesis was to build upon our current understanding of the evolving nature of articular cartilage mechanics by elucidating how changes to structure and composition of the tissue during ... -
Experimental study of aeroacoustic noise production through combined flow measurements and array signal processing
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)The underlying processes behind sound generation in turbulent flows are still a source of debate. The investigation presented in this thesis focuses on the experimental approaches that aim to clarify this issue by estimating ... -
Stochastic failure modelling of total hip replacement
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2009)Failure of total hip replacement (THR) can be a highly variable phenomenon. Many factors of a different nature may affect the outcome of this operation, e.g. loads occuring in the joint, patient geometry, implant design, ... -
The evolution of an impinging synthetic air jet
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)Impinging synthetic jets are considered to offer great potential for many applications, including the thermal management of electronics. In this study, an experimental investigation into the evolution of an impinging ... -
Fundamental investigations into the micromilling of a biomedical grade polymer
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)The demand for polymer micromachining has been rapidly growing for a number of years in various diverse applications. Polymer components are generally produced by moulding; however, in some instances machining may be ... -
Study of pulsating flow in close-coupled catalyst manifolds using phase-locked hot-wire anemometry
(2004)Phase-locked sampling has been applied to hot-wire anemometry in order to investigate the pulsating flow inside two types of automotive exhaust manifolds fitted with a close-coupled catalyst. An isothermal dynamic flow ... -
Thermal cycling of thermoelectric generators: The effect of heating rate
(2019)Thermoelectric generators, or TEGs, are solid state devices which can convert heat directly into electricity according to the Seebeck effect. When thermoelectric generators are subjected to thermal cycling they can undergo ... -
Facing the Information Leaks in Industrial Water Systems: A Concept for Proxy Measurements to Support Water Metering Audits
(2018)Water optimisation methods and water benchmarking are receiving growing attention in manufacturing surroundings. A basic requirement for any of these approaches is a water metering audit. However, missing ... -
Experimental study of flow dynamics in close-coupled catalyst manifolds
(2007)Time-resolved flow dynamics in an automotive exhaust manifold with close-coupled catalyst are investigated experimentally on a charged motored engine (CME) flow rig. Flow similarity between CME ... -
The theory of critical distances applied to multiscale toughening mechanisms
(2019)The Theory of Critical Distances (TCD) is an approach used for predicting the effect of cracks and notches on fracture and fatigue behaviour. In recent years it has been successfully applied to a wide range of problems ... -
An investigation into the role of substrate stiffness and oxygen availability in the regulation of stem cell differentiation during tissue regeneration
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)Mesenchymal stem cells (MSCs) are multipotent cells which can differentiate down multiple lineages and potentially generate tissues such as cartilage, bone or adipose tissue. It is becoming increasingly clear that mechanical ... -
Bio-inspired Aerodynamic Noise Control: A Bibliographic Review
(2019)It is well-known that many species of owl have the unique ability to fly silently, which can be attributed to their distinctive and special feather adaptations. Inspired by the owls, researchers attempted to reduce the ... -
Hybrid additive manufacture of 316L stainless steel with cold spray and selective laser melting: microstructure, mechanical properties and case study
(ASM International, 2019)A novel hybrid additive manufacturing process was proposed and utilized for the production of 316L stainless steel components in this work. It combines selective laser melting (SLM) and cold ... -
The Effect of Calcium and Glucose Concentration on Corneal Epithelial Cell Lines Differentiation, Proliferation, and Focal Adhesion Expression.
(2019)It is known that culture media composition can affect cell behavior, morphology, and gene expression. However,in the case of corneal epithelial cells, the combined role of calcium and glucose concentration in media has not ... -
Property enhancement of cold sprayed Al-diamond MMC coating by using core-shelled diamond reinforcements
(ASM International, 2019)Super wear-resistance and light-weight Al-based metal matrix composite (MMC) coatings were produced using cold spray. Cu-Ni coated diamond with core-shell structure and pure diamond were used as reinforcing ... -
The influence of additive manufacturing processes on the performance of a periodic acoustic metamaterial
