Investigations into the mechanical properties of insect cuticle
(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. ... -
A biomechanical analysis of the trunk and spine during paediatric cerebral palsy gait
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2017)Movement pathologies in the lower limbs of children with cerebral palsy are well established in the literature. However, movement pathologies of the upper body, in particular the trunk, are less well defined. Mechanical ... -
Modulating mechanical cues and oxygen availability to regulate chondrogenesis within MSC laden hydrogels
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2017)Tissue engineering is a potential alternative to conventional surgical techniques for regenerating damaged tissues that lack the ability to spontaneously repair. MSCs are a promising cell source for tissue engineering ... -
The development of an active implantable neural probe system for chronic use
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2017)The alleviation of symptoms of debilitating neural conditions via neural probes is an increasingly important area of research. However, the effectiveness of these probes decreases over time due to the formation of a glial ... -
Mechanics of the linea alba and suture-based wound closure
(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 ... -
A Biomechanical Assessment of Direct and Inertial Head Loading in Rugby Union
(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 ... -
Numerical modelling of directional solidification in metal alloys
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)Manufacturing routes for metal alloy components often involve solidification processes. In order to obtain a product that meets given requirements in terms of mechanical properties, the ability to predict the grain structure ... -
Spatial presentation of tissue specific extracellular matrix components and growth factors on porous electrospun fibre scaffolds for bone-ligament interface tissue engineering
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)In many clinical situations ligament or tendon replacements are required, such as for the surgical replacement of a torn anterior cruciate ligament (ACL). The current ‘gold standard’ treatment is resection of the torn ... -
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 ... -
Tension and compression stress-strain asymmetry in passive skeletal muscle
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2017)The general aim of this study is to advance the knowledge of the relationship between the skeletal muscle passive compressive and tensile behaviour, and the microstructure of the muscle through combined experimental, ... -
An improved framework for the inverse analysis of skeletal muscle tissue in-vivo
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)This thesis focusses on the development of an experimental and computational framework for the non-invasive analysis of the passive mechanical properties of living human skeletal muscle tissue. This is relevant to many ... -
Quantitative accoustic analysis of inhaler sounds for the objective assessment of inhaler adherence in patients with chronic respiratory diseases
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)Asthma and chronic obstructive pulmonary disease (COPD) are two of the most prevalent chronic respiratory disorders. Over 800 million people suffer from these diseases and over four million people die annually. Although ... -
An optimized surface topography for calcium phosphate bone tissue engineering scaffolds
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)Improved scaffold/host integration and avoiding core necrosis are important and active goals in tissue engineering. Alternatives to bone tissue grafting that are highly bioactive and inexpensive to manufacture are clinical ... -
Flow structures and heat transfer enhancement in the wakes of sliding bubbles
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)The motion of a bubble through a fluid has attracted considerable scientific attention for many years due to the complex, interesting fluid dynamics in their wakes, coupled to a rich and varied interface motion. Additionally, ... -
Reconfigurable manufacturing process monitoring systems
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)Performance measurement is indispensable to manufacturing, due to the fact that if the efficiency of an activity cannot be measured it could not be effectively controlled. Recent trends in process monitoring systems point ... -
