CASCADE methodology and tool: appliedICT for energy efficient airports
(World SB14 Barcelona, 2014-10-28)This paper gives an overview on the CASCADE project, methodology and on a stakeholdercentered solution called the CASCADE Tool that integrates Fault Detection and Diagnosis (FDD)into a comprehensive energy management ... -
Catalytic potential of selected metal ions for bioleaching, and potential techno-economic and environmental issues: a critical review
(Elsevier, 2017-01-06)Bioleaching is considered to be a low-cost, eco-friendly technique for leaching valuable metals from a variety of matrixes. However, the inherent slow dissolution kinetics and low metal leaching yields have restricted its ... -
Changes in the fractionation profile of Al, Ni and Mo during bioleaching of spent hydroprocessing catalysts with Acidithiobacillus ferrooxidans.
(Taylor & Francis, 2018-06-05)Spent hydroprocessing catalysts are known to contain a variety of potentially toxic metals and therefore studies on the bioavailability and mobility of these metals are critical for understanding the possible environmental ... -
Changing energy cultures? Household energy use before and after a building energy efficiency retrofit
(Elsevier, 2019-12-03)Government- and community-initiated energy retrofits of existing residential buildings abound across Europe. This paper argues that retrofitting initiatives need to extend their current emphasis on technical-material changes ... -
Characterisation of Irish-grown Scots pine timber for structural applications
(National University of Ireland Galway, 2020-08-27)There is very little knowledge on the timber quality of the native Scots pine grown in Ireland, and its potential to produce timber for structural applications. This paper studied the mechanical performance in tension and ... -
Characterisation of Irish-grown Scots pine timber for structural applications
(Civil Engineering Research in Ireland, 2020)There is very little knowledge on the timber quality of the native Scots pine grown in Ireland, and its potential to produce timber for structural applications. This paper studied the mechanical performance in tension and ... -
Characterization of separated pig manure composted with a variety of bulking agents at low initial C/N ratios
(2011)The aim of this study was to investigate the composting of separated pig manure solids with or without a variety of bulking agents at a low initial C/N ratio (12.5-23.3). Compost stability was investigated using an oxygen ... -
Chemical amendment of pig slurry: control of runoff related risks due to episodic rainfall events up to 48 hours after application.
(2013)Losses of phosphorus (P) from soil and slurry during episodic rainfall events can contribute to eutrophication of surface water. However, chemical amendments have the potential to decrease P and suspended solids (SS) losses ... -
Combining engineering and qualitative models to fault diagnosis in air handling units
(IOS Press, 2014-08-18)This paper presents a methodology for model-based fault localization and identification that exploits both numerical (Modelica) models and a qualitative model-based approach to diagnosis. It has been applied to diagnosis ... -
Community engaged learning: A building engineering case study
(Civil Engineering Research Association of Ireland (CERAI), 2020-08-28)ABSTRACT: Community engaged learning is a form of experiential education with a civic underpinning. Community engaged learning is embedded with the civil engineering curriculum at NUI Galway and is framed by a research ... -
Comparison of a stratified and a single-layer laboratory sand filter to treat dairy soiled water from a farm-scale woodchip filter
(Springer, 2014-04)Washing-down parlours and standing areas, following milking on dairy farms, produces dairy soiled water (DSW) that contains variable concentrations of nutrients. Aerobic woodchip filters can remove organic matter, nutrients ... -
A computational toolchain for the automatic generation of multiple Reduced-Order Models from CFD simulations
(Elsevier, 2019-05-25)This paper describes the development of a systematic tool chain capable of automatically extracting accurate and efficient Reduced-Order Models (ROMs) from Computational Fluid Dynamics (CFD) simulations. These ROMs can ... -
Consequences of varied soil hydraulic and meteorological complexity on unsaturated zone time lag estimates.
(Elsevier, 2014-10-13)The true efficacy of a programme of agricultural mitigation measures within a catchment to improve water quality can be determined only after a certain hydrologic time lag period (subsequent to implementation) has elapsed. ... -
Constructed wetlands for the treatment of highway runoff.
(Nova Publishers, 2008-06-01)Highway surface runoff contains pollutants such as total suspended solids (TSS), hydrocarbons, de-icing salts, and heavy metals. Treatment methods for highway runoff include storage/treatment facilities, such as constructed ... -
Contrasting yield responses to phosphorus applications on mineral and organic soils from extensively managed grasslands: Implications for P management in high ecological status catchments
(Wiley, 2018-09-13)Phosphorus (P) loss from grassland production is one of the main causes affecting high status water bodies in Europe. Soils with a high content in organic matter (OM), even if extensively managed, are particularly vulnerable ... -
The creation of a living laboratory for structural engineering at the National University of Ireland, Galway
(2012)The recently completed New Engineering Building (NEB) at the National University of Ireland, Galway (NUIG) is a new state of the art academic facility on the university's north campus. The building unites all five ... -
Creep improvement factors for vibro-replacement design
(ICE Publishing, 2017-02)Although the vibro-replacement stone column technique is being deployed increasingly in soft cohesive soil deposits in which creep settlements may be significant/dominant, the majority of existing stone column settlement ... -
Cyclic loading tests on sandstone and limestone shale aggregates used in unbound forest roads
(Elsevier, 2009)This study examined the performance of two aggregates subjected to cyclic loading in a large-scale test rig. The two aggregates examined were: (i) a sandstone from Co. Cork, Ireland and (ii) a limestone shale from Co. ... -
