Deep neural network and data augmentation methodology for off-axis iris segmentation in wearable headsets
(Elsevier, 2019-08-01)A data augmentation methodology is presented and applied to generate a large dataset of off-axis iris regions and train a low-complexity deep neural network. Although of low complexity the resulting network achieves a high ... -
Instrumented single and group piles in Belfast soft clay
(Australian Geomechanics Society, 2000-12)The paper presents a number of key findings from an experimental pile test programme, which is currently underway at a soft clay test bed site on the outskirts of Belfast, Northern Ireland. These findings provide additional ... -
Observed installation effects of vibro-replacement stone columns in soft clay
(National University of Ireland Galway, 2008-09-03)The installation of vibro replacement stone columns in any soil causes significant changes to the stress regime around each probe location. In soft clays, the principal effects are caused by a cavity expansion mechanism ... -
Is geotechnical education meeting industry demands? The Irish position
(National University of Ireland Galway, 2008-06-02)This paper presents the results of a survey carried out in late 2007 to gauge how geoengineering education is perceived to meet the demands of Irish industry. The survey was internet-based and the responses provide some ... -
Experimental investigation of the response of a driven pile in soft silt
(National University of Ireland Galway, 2004-12-01)The paper describes the results of field tests carried out using highly instrumented piles at a very soft estuarine clayey silt deposit at Kinnegar, Belfast. The site has been used for a number of years as a geotechnical ... -
Stress changes associated with driving pile groups in clayey silt
(National University of Ireland Galway, 2003)Measurements obtained from lateral total stress sensors located on the centre pile of a small driven pile group and pneumatic piezometers installed in the vicinity of the group are used to assess the disturbance associated ... -
Measured and predicted t-z curves for a driven pile in lightly overconsolidated silt
(National University of Ireland Galway, 2008-04-03)Data from a static compression load test on a single driven pile in a lightly overconsolidated silt are presented in this paper. The pile was equipped with vibrating wire strain gauges along its length enabling its load ... -
Laboratory foundation model with pyrite-bearing mudstone fill
(Thomas Telford (ICE Publishing), 2017-11-29)Damage to domestic dwellings in the greater Dublin area of Ireland engendered by the expansion of the underfloor fill material containing pyrite has become a high-profile national problem in recent years. In this paper, a ... -
Novel use of peatlands as future locations for the sustainable intensification of freshwater aquaculture production - A case study from the Republic of Ireland
(Elsevier, 2019-12-10)There has been an increasing interest in enhancing freshwater aquaculture processes without hindering the progress of the Water Framework Directive. This constitutes the first study to describe a new concept in integrated ... -
Appraisal and ranking of poly-aluminium chloride, ferric chloride and alum for the treatment of dairy soiled water
(Elsevier, 2020-04-29)Land spreading of dairy soiled water (DSW) may result in pollution of ground and surface waters. Treatment of DSW through sludge-supernatant separation using chemical coagulants is a potential option to reduce the negative ... -
Dredged marine sediments stabilized/solidified with cement and GGBS: Factors affecting mechanical behaviour and leachability
(Elsevier, 2020-04-08)Management strategies for the safe disposal of contaminated dredged marine sediment are a global scale environmental issue. Stabilization/solidification method was investigated as a sustainable approach for the potential ... -
Operational fatigue loading on tidal turbine blades using computational fluid dynamics
(Elsevier, 2020-01-20)As the world moves to a greater reliance on renewable energy, a vital component will be the predictability and dependability of the energy source; tidal energy provides such a solution. Horizontal axis tidal turbines are ... -
Flexural reinforcement of glue-laminated timber beams using prestressed FRP plates.
(NetComposites Limited, 2009-09-01)Fibre-reinforced polymer (FRP) plates have been used successfully to enhance the structural performance of glue-laminated (glulam) timber beams. Unreinforced glulams usually fail in tension in a brittle fashion. The addition ... -
Review of state of the art dowel laminated timber members and densified wood materials as sustainable engineered wood products for construction and building applications
(Elsevier, 2019-12-10)Engineered Wood Products (EWPs) are increasingly being used as construction and building materials. However, the predominant use of petroleum-based adhesives in EWPs contributes to the release of toxic gases (e.g. Volatile ... -
Pyrolysed waste materials show potential for remediation of trichloroethylene-contaminated water.
(Elsevier, 2019-12-17)Trichloroethylene (TCE) is an Environmental Protection Agency priority pollutant associated with cancer in humans. With numerous industrial applications and regular landfill disposal, TCE is a common landfill leachate ... -
Pre-culture of mesenchymal stem cells within RGD-modified hyaluronic acid hydrogel improves their resilience to ischaemic conditions
(Elsevier, 2020-03-04)The incorporation of the RGD peptide (arginine-glycine-aspartate) into biomaterials has been proposed to promote cell adhesion to the matrix, which can influence and control cell behaviour and function. While many studies ... -
An actuatable soft reservoir modulates host foreign body response
(American Association for the Advancement of Science, 2019-08-28)The performance of indwelling medical devices that depend on an interface with soft tissue is plagued by complex, unpredictable foreign body responses. Such devices—including breast implants, biosensors, and drug delivery ... -
User acceptance of mandated technology: An analysis of the role of moderating factors
(Elsevier, 2020-01-28)This research assesses how the characteristics of age, gender and personality influence user acceptance of a software system in a mandated industrial setting. Guided by a conceptual framework based on the Unified Technology ... -
High-resolution measurements of leakage flow inside the hinge of a large-scale bileaflet mechanical heart valve hinge model
(Springer, 2019-06-24)Purpose It is believed that non-physiological leakage flow through hinge gaps during diastole contributes to thrombus formation in Bileaflet Mechanical Heart Valves (BMHVs). Because of the small scale and difficulty of ... -
Estrogen deficiency impairs integrin αvβ3-mediated mechanosensation by osteocytes and alters osteoclastogenic paracrine signalling
