A finite element-based approach for predictions of rigid pile group stiffness efficiency in clays
(Springer Verlag, 2013-08-17)This paper presents a finite element parametric study of several variables that affect the stiffness efficiency of rigidly capped pile groups with a view to developing a solution for preliminary design purposes. Previous ... -
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 ... -
Flipped learning in a civil engineering module: student and instructor experiences
(Irish Learning Technology Association, 2018-08-24)Flipped learning is a form of active learning in which the basic content is assimilated before scheduled classroom sessions, enabling more productive use of classroom time to cultivate problem-solving ability, a key ... -
Formal Calibration methodology for a CFD model of a naturally ventilated room
(2011)This paper describes a systematic methodology for the development of calibrated thermodynamic Computational Fluid Dynamics (CFD) models for controlled environments in buildings utilising wireless sensor networks. ... -
Formal calibration methodology for CFD model development to support the operation of energy efficient buildings
(Texas A&M University, 2010)Computational Fluid Dynamics (CFD) is a robust tool for modelling interactions within and between fluids and solids. CFD can help understand and predict phenomena that are difficult to test experimentally leading ... -
Formal calibration methodology for CFD models of naturally ventilated indoor environments
(Elsevier, 2012-08-31)Well planned natural ventilation strategies and systems in the built environments may provide healthy and comfortable indoor conditions, while contributing to a significant reduction in the energy consumed by buildings. ... -
A framework for determining unsaturated zone time lags at catchment scale
(Elsevier Masson, 2016-12-10)The responses of waterbodies to agricultural programmes of measures are frequently delayed by hydrological time lags through the unsaturated zone and groundwater. Time lag may therefore, impede the achievement of remediation ... -
Future phosphorus: advancing new '2D' allotropes and growing a sustainable bio economy
(Crop Science Society of America with American Society of Agronomy and Soil Science Society of America, 2019-07-11)With more than 40 countries currently proposing to boost their national bioeconomies, there is no better time for a clarion call for a new bioeconomy, which, at its core, tackles the current disparities and inequalities ... -
Galway Bay bathymetry comparison from Admiralty Chart and LiDAR datasets.
(2012)The primary objective of this paper was to test the sensitivity of numerical models to bathymetry datasets. Bathymetric datasets used were from; 1) Admiralty Charts and 2) LiDAR & Multi- Beam Echo Sounder surveys. The ... -
Generating robust algorithms for energy efficient lighting as a performance aspect of the building operational energy optimisation framework
(NUI Galway, 2016-08-29)This paper presents a part of the ongoing research in the nZEB-Retrofit project in the National University of Ireland, Galway. This research aims to optimise residential building performance by enhancing the key performance ... -
Global and local fatigue analysis of X100 and X60 steel catenary riser girth welds
(Taylor & Francis, 2017-08-31)The use of steel catenary risers in offshore oil and gas production has increased significantly in recent years, in particular for deepwater applications. This paper presents a detailed assessment approach with respect to ... -
Glued-in basalt FRP rods as moment connections in box section frames
(TU Verlag Wien, 2016-08-22)This paper presents an experimental programme that investigates the application of glued-in rods as moment connections in a post and beam connection. Nine such frame corners were constructed of box sections using ... -
Greenways as a tourism resource: a study of user spending and value
(Taylor & Francis, 2016-01-18)Cycling is increasingly recognized as a key tool in improving transport sustainability, promoting increased physical activity and improved public health and developing the tourism sector. While the provision of safe and ... -
Ground heave induced by installing stone columns in clay soils
(ICE Publishing, 2013-12)Measurements of ground heave induced by installing stone columns in soft clay are presented in this paper. These measurements are likely to provide guidance to practitioners concerned about the possible impact of column ... -
Ground improvement using the vibro- stone column technique
(Institution of Engineers in Ireland, 2007)The Vibro Stone Column technique is one of the most widely-used ground improvement processes in the world, although its potential for improving Irish sites has yet to be fully exploited. Historically the system has been ... -
Habit suitability assessment of constructed wetlands for the Smooth Newt (Lissotriton vulgaris [Linnaeus, 1758]): a comparison with natural wetlands
(Elsevier, 2017-06-22)Given the current decline of natural wetlands worldwide and the consequent negative impacts on amphibians, wetlands constructed for the treatment of wastewaters have the potential to play a role in the protection of these ... -
