Towards the development of a robotic dexterity assessment framework
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2017)The importance of flexible manufacturing processes and small-scale assembly is growing due to the increased pace of globalisation and greater consumer demands for product customisation. To address this trend, there has ... -
TRPV4-mediates oscillatory fluid shear mechanotransduction in mesenchymal stem cells in part via the primary cilium
(2018)Skeletal homeostasis requires the continued replenishment of the bone forming osteoblast from a mesenchymal stem cell (MSC) population, a process that has been shown to be mechanically regulated. However, the mechanisms ... -
Two- and three-dimensional in vitro nucleus pulposus cultures: An in silico analysis of local nutrient microenvironments
(2022)Background It is well established that the unique biochemical microenvironment of the intervertebral disc plays a predominant role in cell viability and biosynthesis. However, unless the effect of microenvironmental ... -
Two-phase flow and heat transfer in reflux thermosyphons
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)Improved cooling technologies are becoming necessary in electronic applications, specifically Radio Frequency Power Amplifiers (RFPA) installed in tower-top Remote Radioheads (RRH). Current methods of cooling are becoming ... -
Ultra-broadband sound absorption in a compact multi-chamber micro-perforated panel absorber with varying depths
(2024)This study presents an enhanced multi-chamber micro-perforated panel absorber (MC-MPPA) with varying sub-chamber depths, offering ultra-broadband low-frequency sound absorption. Traditional micro-perforated panel absorbers ... -
Ultrasonic impact grinding machine tool and process development
(University of Dublin, Trinity College, 2013)Ultrasonic Impact Grinding (UIG) is a mechanical material removal process used to erode holes and cavities in hard and brittle materials such as glass, ceramics, silicon carbide, quartz and ... -
Under surface pressure sensing technique for the evaluation of contact stresses
(2005)In metal forming operations, the intensity and distribution of stresses at the tool/material interface have great influence on the pattern and mode of deformation. This is due to the effect of frictional forces, being ... -
Unravelling the role of mechanical cues on the chondrogenic differentiation of stem cells
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2019)The inability of adult articular cartilage to regenerate has motivated the development of tissue engineering strategies to repair cartilage defects before they progress to osteoarthritis. Common cell based strategies ... -
The Use of CFD for Investigating Fluidelastic Instability in Tube Arrays
(Trinity College Dublin. School of Engineering. Mechanical & Manufacturing Engineering, 2007)There are several applications of tube arrays subject to cross flow in the industry, mostly for heat exchanging. These tubes are subject to forces arising due to the flow, and under certain conditions they can experience ... -
Use of concealed pressure pins to determinate contact stresses in ring compression
(2005)new flexible experimental technique is introduced where a tool base that incorporates sensitive pressure pins is used. An industrial - tool that contains the forging geometry can be placed on top of the ... -
The use of small angle light scattering in assessing strain induced collagen degradation in arterial tissue ex vivo
(2018)Collagen is the predominant load bearing component in many soft tissues including arterial tissue and is therefore critical in determining the mechanical integrity of such tissues. Degradation of collagen fibres is ... -
Using AI for Loss Prediction in a Hybrid Meanline Modelling Method to Deliver Improved Turbocharger Map Prediction
(2021)Meanline modelling approaches remain attractive due to an unrivalled ability to predict full turbine performance maps quickly compared to high fidelity approaches such as CFD, especially in the preliminary design process. ...
