A nested hydrodynamic model incorporating flooding and drying
(2009)A one-way nested version of the hydrobiological model DIVAST (Depth Integrated Velocity and Solute Transport) is introduced. The nested model allows flooding and drying of intertidal areas, a process often present in areas ... -
A nested version of the combined hydrodynamic and water quality model, DIVAST
(2007)The present research deals with the development of a one-way nested version of the combined hydrodynamic and water quality model DIVAST (Depth Integrated Velocity and Solute Transport). Initial research has concentrated ... -
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 ... -
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 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 ... -
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 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 ... -
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 ... -
Parameterization of turbulence models using 3DVAR data
(City University of New York, 2014-01-08)In this research the 3DVAR data assimilation scheme is implemented in the numerical model DIVAST in order to optimize the performance of the numerical model by selecting an appropriate turbulence scheme and tuning its ... -
Perception and use of timber in construction: A case study of Ireland and the UK
(National University of Ireland Galway, 2021-08-09)A survey was carried out to examine the perception of timber in construction among industry stakeholders within northwest Europe. The survey received responses from 17 countries in total. The total results of all ... -
A Performance Assessment Protocol for Structured Mesh Multi-Scale Models
(2011)Nesting techniques are used to develop multi-scale models giving higher resolution and thus greater accuracy in nested domains. The assessment of model accuracy is therefore important for the successful implementation of ... -
Presence of emerging contaminants in treated sludges and their potential impacts on the environment
(NUI Galway, 2018-11-13)Landspreading of sewage sludge remains the most economical and practical means for its disposal, with some countries, such as Ireland, disposing up to 90% to land. Its nitrogen, phosphorus and metal content make it an ... -
Real-time control of occupants thermal comfort in buildings
(International Building Performance Simulation Association, 2015-12-07)Providing satisfactory indoor environmental conditions, air quality and thermal comfort through adequate ventilation is crucial in maintaining safe, healthy and comfortable buildings. Since, heating, ventilation and air ... -
Real-time monitoring and performance of retaining structures
(NUI Galway, 2014-08)The advent of reliable real-time monitoring devices has changed the way we monitor the construction of geotechnical infrastructure. This paper presents a case study where Shaped Accel Arrays (SAA) were employed as part ... -
Real-time monitoring of a hybrid precast and in situ concrete flat slab system
(2014)This paper presents a scheme developed for instrumentation and monitoring of the structural performance of a hybrid precast and in situ concrete flat slab system employed in an educational building. The system contains a ... -
Recovered wood as raw material for structural timber products. Characteristics, situation and study cases: Ireland and Spain
(International Society of Wood Science and Technology (SWST), 2020-07-12)The circular economy is an efficient system to reuse materials reducing the amount of waste generated. In order to implement it in the timber sector, the InFutUReWood (Innovative Design for the Future Use and Reuse of ... -
Reduced order modelling of the thermal behaviour of an office space
(Infoscience EPFL Scientific Publications, 2013-09-04)Reduced Order Models (ROMs) have proven to be a valid and efficient approach to model the thermal behaviour of building zones. The main issues associated with the use of zonal/lumped models are how to (1) divide the domain ... -
