Blackpool South Strategy project: analysis of pipe-jacking records
O’Dwyer, Kevin G.; McCabe, Bryan A.; Sheil, Brian B.; Hernon, David P. (Civil Engineering Research in Ireland CERI, 2018-08-29)In recent years, there has been an increased resort to microtunnelling/pipe-jacking as a means of constructing underground conduits (for water, sewage, gas and other utilities) to avoid on-street disruption in urban areas. ... -
Changes in the fractionation profile of Al, Ni and Mo during bioleaching of spent hydroprocessing catalysts with Acidithiobacillus ferrooxidans.
Pathak, Ashish; Healy, Mark G.; Morrison, Liam (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 ... -
Detecting the end of nitrification in small and decentralized wastewater treatment systems using low-resource real-time control methods
Fox, S.; Clifford, Eoghan (American Society of Civil Engineers, 2018-06-12)There is increasing demand on operators of small-scale wastewater treatment plants (WWTPs) to improve biological nutrient removal and energy efficiency while being subject to unique challenges, including reduced resources. ... -
Influence of soil phosphorus status, texture, pH and metal content on the efficacy of amendments to pig slurry in reducing phosphorus losses
O’ Flynn, Cornelius J.; Fenton, Owen; Wall, David; Brennan, Raymond B.; McLaughlin, Mike J.; Healy, Mark G. (Wiley, 2017-12-13)Cost effective strategies for using chemically amended organic fertilizers need to be developed to minimize nutrient losses in surface and groundwater. Coupling specific soil physical and chemical characteristics with ... -
Interpretation of pipe-jacking and lubrication records for drives in silty soil
O'Dwyer, Kevin G.; McCabe, Bryan A.; Sheil, Brian B. (Elsevier, 2019-04-22)In recent years, there has been an increased resort to microtunnelling/pipe-jacking as a means of constructing underground conduits (for water, sewage, gas, and other utilities) to avoid on-street disruption in urban areas. ... -
Lifecycle environmental and economic performance of nearly zero energy buildings (NZEB) in Ireland
Goggins, Jamie; Moran, Paul; Armstrong, Alan; Hajdukiewicz, Magdalena (Elsevier, 2016-01-16)Directives in the European Union are ensuring that buildings in this region are moving towards nearly zero energy buildings (NZEB). For countries like Ireland, which has a temperate oceanic climate, a key to achieving NZEB ... -
ModSCO. Online Reduced Order Models (ROM) to address the performance gap
Piccinini, Alessandro; Blanes, Luis M.; Seri, Federico; D'Angelo, Letizia; Keane, Marcus M. (MDPI, 2019-07-25)This communication presents ModSCO, a web application that supports systematic energy performance evaluation using Reduced Order Models (ROM). These models are particularly useful in scenario with missing, incomplete or ... -
A novel method to rapidly assess the suitability of water treatment residual and crusted concrete for the mitigation of point and nonpoint source nutrient pollution
Callery, Oisín; Healy, Mark G. (Elsevier, 2019-07-02)Freshwater ecosystems worldwide are at risk of becoming degraded as a result of excessive inputs of phosphorus (P) associated with terrestrial activities. This study describes a novel methodology to rapidly assess the ... -
A novel reduced order model technology framework to support the estimation of the energy savings in building retrofits
Piccinini, Alessandro; Hajdukiewicz, Magdalena; Keane, Marcus M. (Elsevier, 2021-03-13)Energy Performance Contracting (EPC), as a tool to enhance energy efficiency of buildings, can accelerate investment in cost-effective energy conservation measures (ECMs) for existing buildings. However, there are many ... -
A novel ROM methodology to support the estimation of the energy savings under the Measurement and Verification protocol
Piccinini, Alessandro; Hajdukiewicz, Magdalena; D'Angelo, Letizia; Blanes, Luis M.; Keane, Marcus M. (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 ... -
A precipitate evolution-based continuum damage mechanics model of creep behaviour in welded 9Cr steel at high temperature
Ó Murchú, Cathal; Leen, Sean B.; O’Donoghue, Padraic E.; Barrett, Richard A. (SAGE Publications, 2018-04-04)A multiaxial, physically based, continuum damage mechanics methodology for creep of welded 9Cr steels is presented, incorporating a multiple precipitate-type state variable, which simulates the effects of strain- and ... -
Review of EU airport energy interests and priorities with respect to ICT, energy efficiency and enhanced building operation
Costa, Andrea; Blanes, Luis M.; Donelly, Ciara; Keane, Marcus M. (National University of Ireland Galway, 2012-10-23)This paper gives an overview on EU airport energy interests and priorities with respect to ICT, energy efficiency and enhanced building operation. To achieve this objective the paper begins with an overview on airports ...
