Objective and Quantitative acoustic-analysis of musicians dystonia
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2020)Musician s Dystonia (MD) is the most common movement disorder affecting musicians. Being a specific phenotype of Dystonia, MD is a focal, task-specific and painless disorder that affects motor control during musical ... -
On the acoustics of installed subsonic jets
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2009)The reduction of community exposure to aircraft noise is an important consideration in the design of future aircraft. A review is currently under way of novel aircraft configurations, which may exploit the fuselage, wings ... -
On the development of scaffolds for bone tissue engineering
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)Many of the current tissue-engineering scaffold-based strategies have suffered from limited cell depth viability when cultured in vitro, with viable cells existing within the outer 250-500 μm from the fluid-scaffold ... -
On the use of indentation technique to assess fracture properties of ceramics at the microscale
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Classic methods to determine fracture properties of ceramics (like Single-Edge Notched Beam or Compact Tension) are accurate at the macroscale but inappropriate to estimate local fracture properties which are decisive at ... -
Optimisation of process parameters and tooling during friction stir welding of AA2024-T3
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2011)Friction stir welding (FSW) was invented and experimentally proven at The Welding Institute (TWI) in 1991. The process involves the joining of two metal pieces without melting by joining their molecules together. The tool ... -
Passive mechanical properties of skeletal muscle in compression
(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 ... -
Plate-type Acoustic Valve Resonator for, Low-frequency Sound Absorption
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2024)Plate-type acoustic metamaterials with deep-subwavelength thickness have generated considerable enthusiasm for addressing low-frequency noise. These metamaterials can be tailored to obtain high absorption efficiency by ... -
Polymer / clay nanocomposites
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2012)Polymer/clay nanocomposites are a new class of materials with unique properties that are not shared by the pristine polymers or the conventional composites. These materials may present enhanced mechanical, themial, barrier ... -
Post-menopausal osteoporosis and the effect of remodelling on bone material
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)This work concerns the relationship between bone and its environment and how changes in this environment affect its mechanical behaviour. More particularly, it concerns how the alteration of this environment following ... -
Power and position-oriented process monitoring of freeform abrasive machining
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2013)Abrasive machining is used for the generation of freeform femoral implant surfaces in the biomedical industry. The abrasive machining operation is typified by high speed material removal in multiple axes, difficult-to-machine ... -
Prediciton of fatigue failure in engineering components using the finite element method
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2000)Prediction of fatigue failure in engineering artefects is becoming increasingly important as we enter the third millennium; more catastrophic fatigue failures will occur as engineers push the limits of design even further ... -
Process, precedent, and community : new learning environments for engineering design
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2014)Project-based design courses are an increasingly conunon component of engineering education. Most engineering schools have traditionally emphasized the analytical and scientific aspects of the discipline, and an increase ... -
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 ...
