A High-Precision Apparatus for the Characterization of Thermal Interface Materials
(American Institute of Physics, 2009)An apparatus has been designed and constructed to characterize thermal interface materials with unprecedented precision and sensitivity. The design of the apparatus is based upon a popular implementation of ASTM D5470 ... -
High-resolution hot-film measurement of surface heat flux to an impinging jet
(2011)To investigate the complex coupling between surface heat transfer and local fluid velocity in convective heat transfer, advanced techniques are required to measure the surface heat flux at high spatial and temporal resolution. ... -
How context shapes the appropriateness of a robot's voice
(2020)Social robots have a recognizable physical appearance, a distinct voice, and interact with users in specific contexts. Previous research has suggested a 'matching hypothesis', which seeks to rationalise how people judge a ... -
How might people near national roads be affected by traffic noise as electric vehicles increase in number? A laboratory study of subjective evaluations of environmental noise
(2016)We face a likely shift to electric vehicles (EVs) but the environmental and human consequences of this are not yet well understood. Simulated auditory traffic scenes were synthesized from recordings of real conventional ... -
How to design, develop and build a fully-integrated melt electrowriting 3D printer
(2022)Melt electrowriting (MEW) is a high resolution material extrusion based additive manufacturing process with the unique capability to produce micron to sub-micron diameter fibres and control their deposition in three ... -
Human bone marrow stem/stromal cell osteogenesis is regulated via mechanically activated osteocyte-derived extracellular vesicles
(2020)Bone formation or regeneration requires the recruitment, proliferation, and osteogenic differentiation of stem/stromal progenitor cells. A potent stimulus driving this process is mechanical loading. Osteocytes are ... -
HUMAN IN THE LOOP CONTROL IN ROBOTICS FOR MANUFACTURING
(2015)Traditional manufacturing processes are limited to either being fully automated (CNC machining, robotic packaging, robotic welding systems, etc.), or fully manual (assembly tasks, hand tool operation, etc.), with 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 ... -
Hydrodynamics and heat transfer of laminar pulsating flow in a rectangular channel
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2017)The exploitation of flow pulsation is a potentially useful technique for enhanced cooling in single-phase cooling systems. This thesis contains parametric analyses of the hydrodynamics and heat transfer of a laminar ... -
Hydrogen peroxide as a clinical irrigation solution: A comparative study of the effect of hydrogen peroxide versus normal saline on the strength of the bone-cement interface
(IOS Press, 2007)Hydrogen peroxide has been used for decades as an effervescent haemostatic agent in arthroplasty. Recently it has been shown to adversely affect the material properties of PMMA. We aim to assess whether any such deleterious ... -
Hydrostatic pressure acts to stabilise a chondrogenic phenotype in porcine joint tissue derived stem cells.
(2012)Hydrostatic pressure (HP) is a key component of the in vivo joint environment and has been shown to enhance chondrogenesis of stem cells. The objective of this study was to investigate the interaction between HP and ... -
Hydrostatic pressure promotes chondrogenic differentiation and microvesicle release from human embryonic and bone marrow stem cells
(2022)Mechanical stimulation plays in an important role in regulating stem cell differentiation and their release of extracellular vesicles (EVs). In this study, effects of low magnitude hydrostatic pressure (HP) on the chondrogenic ... -
Hydrostatic Pressure Regulates the Volume, Aggregation and Chondrogenic Differentiation of Bone Marrow Derived Stromal Cells
(2021)The limited ability of articular cartilage to has motivated the development of tissue engineering strategies that aim to harness the regenerative potential of mesenchymal stem/marrow stromal cells (MSCs). Understanding ... -
Hypothesis testing of glenoid component innovation in total shoulder arthroplasty
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)A glenoid component with reliable long-term performance does not exist for total shoulder arthroplasty. Poor glenoid component durability may be explained by the huge variability that exists at the shoulder joint ... -
Hypoxia mimicking hydrogels to regulate the fate of transplanted stem cells
(2019)Controlling the phenotype of transplanted stem cells is integral to ensuring their therapeutic efficacy. Hypoxia is a known regulator of stem cell fate, the effects of which can be mimicked using hypoxia-inducible factor ... -
Identification and Measurement of Variables Affecting Component Lifetime: A Case Study of Polymer Degradation in the Biopharmaceutical Industry
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)Modern maintenance methods are dependent upon understanding and monitoring component degradation; however, many industrial situations exist where monitoring is impossible, and component degradation mechanisms are not well ... -
