Cold sprayed FeCoNiCrMn High Entropy Alloy (HEA) coating: microstructure and tribological property
(ASM International, 2019)High entropy alloys (HEAs) are of great interest in the community of materials science and engineering due to their unique phase structure. They are constructed with five or more principal alloying elements in equimolar ... -
The Effect of In Process Heat Treatment on the Mechanical Properties of Cold Spray Coatings
(ASM International, 2019)Cold spray (CS) is an additive manufacturing process which has recently gained interest within research and select high-end production systems; however, one of the primary factors limiting the deployment of this process ... -
Sensitivity of the damping controlled fluidelastic instability threshold to mass ratio, pitch ratio and Reynolds number in normal triangular arrays
(2018)Sensitivity of the damping controlled fluidelastic instability threshold of normal triangular tube arrays has been investigated through a theoretical-CFD hybrid methodology without the need for experimental data. ... -
CFD modelling of the cross-flow through normal triangular tube arrays with one tube undergoing forced vibrations or fluidelastic instability
(2016)A CFD methodology involving structure motion and dynamic re-meshing has been optimized and applied to simulate the unsteady flow through normal triangular cylinder arrays with one single tube undergoing either forced ... -
Ciliotherapy Treatments to Enhance Biochemically- and Biophysically-Induced Mesenchymal Stem Cell Osteogenesis: A Comparison Study
(2019)New approaches to treat osteoporosis have focused on promoting bone formation through the targeting of osteoblasts and their progenitors, mesenchymal stem cells (MSCs). The primary cilium is a singular cellular extension ... -
Estrogen deficiency impairs integrin ¿vß3-mediated mechanosensation by osteocytes and alters osteoclastogenic paracrine signalling.
(2019)The integrin αvβ3 has been shown to play an important role in osteocyte mechanotransduction. It has been reported that there are fewer β3 integrin-containing cells in osteoporotic bone cells. Osteocytes cultured in vitro ... -
TGFß1 - induced recruitment of human bone mesenchymal stem cells is mediated by the primary cilium in a SMAD3-dependent manner.
(2016)The recruitment of mesenchymal stem cells (MSCs) is a crucial process in the development, maintenance and repair of tissues throughout the body. Transforming growth factor-β1 (TGFβ1) is a potent chemokine essential for the ... -
An Experimental Characterization on the Acoustic Performance of Forward/Rearward Retraction of a Nose Landing Gear
(2019)The modern undercarriage system of a large aircraft normally requires the landing gear to be retractable. The nose landing gear, installed in the front of the fuselage, is retracted either forward or rearward. In the ... -
Vortex shedding lock-in due to pitching oscillation of a wind turbine blade section at high angles of attack
(2019)The unsteady flow around a pitching two-dimensional airfoil section (NREL S809) has been simulated using unsteady RANS with the transition SST turbulence model. This geometry is chosen to represent a wind turbine blade in ... -
The Influence of Additive Manufacturing Processes on the Performance of a Periodic Acoustic Metamaterial
(2019)Advancements in 3D print technology now allow the printing of structured acoustic absorbent materials at the appropriate microscopic scale and sample sizes. The repeatability of the fundamental cell unit of these metamaterials ... -
Characterization of the aircraft bay/landing gear coupling noise at low subsonic speeds and its suppression using leading-edge chevron spoiler
(Sage Publications, 2019)When the aircraft opens the bay door to let the landing gear either drop or retract, the incoming flow will result in a significant amount of coupling noise from the bay and the landing gear. Here, an experimental study ... -
Does ball carrier technique influence tackler head injury assessment risk in elite rugby union?
(2019)The aim of this study was to use video evidence of tackles in elite level rugby union to identify ball carrier proficiency characteristics, for both lower and upper body tackles, that have a higher propensity to result in ... -
Age-related responses to injury and repair in insect cuticle
(The Company of Biologists Ltd, 2019)We evaluated the ability of female adult desert locusts (Schistocercagregaria) to repair injuries to their exoskeletons and restore mechanical strength over the course of their natural life. We discovered that younger ... -
Deciphering the Molecular Mechanisms of Stem Cell Mechanotransduction: A New Avenue for the Development of Therapeutics for Osteoporosis
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2019)Osteoporosis is characterised by reduced bone density and weakened bone architecture leading to high fracture risk. The changes in bone result from an imbalance in the bone remodelling cycle whereby the rate of resorption ... -
Foreword: Special Section on Data Center Cooling
(Institute of Electrical and Electronics Engineers (IEEE), 2017)Data centers account for a significant and growing fraction of the worldwide electricity demand, rising by an average of 11% per year from 2000 to a consumption of 27.1 GW in 2010, representing 1.3% of the total worldwide ... -
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 ... -
Sleeve Pneumatic Artificial Muscles for Antagonistically Actuated Joints
(2019)Pneumatic artificial muscles (PAMs) have been researched for applications in powered exoskeletons, orthosis and robotics. Their high force to mass ratio, low cost and inherent compliance are particularly ... -
Predictive capacity of the MADYMO Multibody human body model applied to head kinematics during rugby union tackles
(MDPI - Applied Sciences, 2019)Multibody models have not yet been evaluated for reconstructing head kinematics during sports impacts. Accordingly, the goal of this study was to utilise whole-body motion data from twenty upper and mid/lower trunk rugby ... -
In vitro co-culture and ex vivo organ culture assessment of primed and cryopreserved stromal cell microcapsules for intervertebral disc regeneration
(2019)Priming towards a discogenic phenotype and subsequent cryopreservation of microencapsulated bone marrow stromal cells (BMSCs) may offer an attractive therapeutic approach for disc repair. It potentially obviates ... -
The effect of stress concentrations on fatigue and fracture of 316L stainless steel micro-scale components
