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 ... -
HRIR Factorisation: A Regularised Approach
(2010)HRIR factorisation allows the extraction of a common direction in- dependent component from a set of HRIRs leaving a set of rela- tively short direction dependent filters and provides both memory and computational savings ... -
HRTF Clustering for Robust Training of a DNN for Sound Source Localization
(2022)This study shows how spherical sound source localization of binaural audio signals in the mismatched head-related transfer function (HRTF) condition can be improved by implementing HRTF clustering when usingmachine learning. ... -
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 ... -
A Hydrogeological Study of Irish Holy wells
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2021)The overall aim of the research was to characterise the hydrogeology and water chemistry of Irish holy wells. The first main research task was an analysis of the distribution of Irish holy wells (listed in a national ... -
Hydrological and hydrochemical supporting conditions for Irish calcareous fen vegetation
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2023)Calcareous fens are listed in Annex 1 of the European Union (EU) Habitats Directive (Council Directive 92/43/EEC, habitat code 7230, 7210 and 7140) as habitats requiring special conservation measures, including the designation ... -
Hydropower energy recovery form the water supply network : feasibility, risk analysis, optimisation and implementation
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2015)The provision of clean and reliable water supply is highly energy intensive. Recent research has focused on the development and application of energy and hydraulic efficiency measures to streamline water usage and improve ... -
Hydropower Energy Recovery from Water Supply Networks Using Pump-As-Turbines: Optimal Selection, Prediction of Global Efficiency, Economic Viability and Large-Scale Resource Assessment
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2021)It is well documented in the literature that the drinking water sector is among the most energy intensive sectors in developed countries. This is because all processes involved in their operation such as extraction, treatment ... -
Hydropower Energy Recovery Systems: Development of Design Methodologies for Pumps As Turbines in Water Networks
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2020)Given the urgency of tackling the challenges offered by climate change and natural resource depletion, it is a priority to increase the sustainability of the water industry by reducing its energy demand and associated ... -
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.
