A novel ROM methodology to support the estimation of the energy savings under the Measurement and Verification protocol
(National University of Ireland Galway, 2020-09-21)This paper presents a novel Reduced Order grey box Model (ROM) methodology, based on a ResistorCapacitor (RC) network, which supports the creation of the baseline energy consumption and the estimation of energy savings ... -
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 ... -
Numerical investigation of reinforcement of timber elements in compression perpendicular to the grain using densified wood dowels
(Elsevier, 2021-03-27)In recent years, the construction industry has seen a greater focus on the use of sustainable construction materials to reduce the environmental impact of buildings. Timber is one such material that has seen a revival in ... -
Numerical investigation of the structural behaviour of adhesive free connections utilising modified wood
(National University of Ireland Galway, 2021-08-09)An investigation was carried out to examine the potential to use modified wood as a replacement for metallic connections in timber structures. In recent years, there have been several studies examining the potential to ... -
Numerical model for steel brace members incorporating a fatigue model
(2013)The aim of this paper is to develop a robust numerical model for cold-formed steel square and rectangular structural hollow sections for use as axial loaded members in earthquake engineering applications. Pseudo-static ... -
Numerical modelling of pile foundation angular distortion
(Elsevier, 2015-05-16)In this paper, the PLAXIS 3-D Foundation finite element (FE) software package, in conjunction with the nonlinear Hardening Soil (HS) constitutive model, is employed in an extensive parametric study of the angular distortion ... -
Numerical modelling of the improvements to primary and creep settlements offered by granular columns
(Springer-Verlag, 2013)Analytical vibro-replacement design approaches typically quantify the settlement reduction using a dimensionless settlement improvement factor, defined as the ratio of the settlements without and with treatment. Most ... -
Numerical modelling to aid in the structural health monitoring of wave energy converters
(2013)A vital aspect of ensuring the cost effectiveness of wave energy converters (WECs) is being able to monitor their performance remotely through structural health monitoring, as these devices are deployed in very harsh ... -
Numerical simulation and assessment of the effects of inlet configuration on the flushing time of a potable water service reservoir
(Conferences and Events at DigitalCommons@USU, 2018-05-15)Service reservoirs provide the dual function of balancing supply with demand and providing adequate pressure in the water supply network by maintaining sufficient pressure head. In a potable water service reservoir, the ... -
Numerical simulation of linear water waves and wave-structure interaction
(2012)One of the main stages in the design of wave energy converters (WEC's) is the numerical modelling of a given converter. In this paper, the numerical simulation of both linear deep water waves and linear waves for the finite ... -
A numerical study of factors affecting the performance of stone columns supporting rigid footings on soft clay
(Taylor and Francis, 2010)The Vibro Replacement technique is now frequently used as a means of improving the bearing capacity and settlement performance of soft cohesive soils. In this paper, a parametric study using the finite element method is ... -
Numerical study of FRP reinforced timber members subjected to variable climates
(SHATiS International Conference on Structural Health Assessment of Timber Structures, 2019-09-25)The use of FRP reinforcement, even in small percentages, has been shown to improve the short-term flexural behaviour of timber members. This technology has been successfully used in new construction and in the repair and ... -
Nutrient dynamics in a peatland forest riparian buffer zone and implications for the establishment of planted saplings
(2012)Forestry on peatland throughout the world is now focused on minimising destructive effects to the surrounding environment, especially during harvesting. These effects may be mitigated through the use of well-developed ... -

Nutrient dynamics in Cork Harbour
(2005)Estuaries are commonly characterised by high productivity due to frequent if not continuous inputs of nutrients from domestic and industrial discharge effluents and from freshwater and marine sources. These forms of nutrient ... -
Nutrient, metal and microbial loss in surface runoff following treated sludge and dairy cattle slurry application to an Irish grassland soil
(Elsevier, 2015)Treated municipal sewage sludge ( biosolids ) and dairy cattle slurry (DCS) may be applied to agricultural land as an organic fertiliser. This study investigates losses of nutrients in runoff water (nitrogen (N) and ... -
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 ... -
On-farm treatment of dairy soiled water using aerobic woodchip filters
(Elsevier, 2011)Dairy soiled water (DSW) is produced on dairy farms through the washing-down of milking parlours and holding areas, and is generally applied to land. However, there is a risk of nutrient loss to surface and ground waters ... -
Operational coefficient of consolidation around a pile group driven in clay/silt
(Springer-Verlag, 2013)Although finite element packages facilitating coupled consolidation analyses are increasingly in use, many practitioners still favour linear uncoupled analysis out of familiarity with the use of coefficients of consolidation. ... -
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 ...
