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. ... -
Using Tactile Sensing to Improve Performance when Grasping Moving Objects
(2021)To operate in unstructured settings, robots require control strategies that effectively respond to temporal changes in their environment. In the domain of robotic manipulation, most state-of-the-art approaches assume the ... -
Utilizing Osteocyte Derived Factors to Enhance Cell Viability and Osteogenic Matrix Deposition within IPN Hydrogels.
(2020)Many bone defects arising due to traumatic injury, disease, or surgery are unable to regenerate, requiring intervention. More than four million graft procedures are performed each year to treat these defects making bone ... -
A validated numerical-experimental design methodology for a movable supersonic ejector compressor for waste-heat recovery
(2013)The aim of this paper is to develop the technical knowledge, especially the optimum geometries, for the design and manufacturing of a supersonic gas-gas ejecto r for a waste heat driven vehicle cooling system. Although ...
