Analysis of the behaviour of hybrid concrete lattice girder slabs during construction using laboratory and field testing
(NUI Galway, 2020-01-31)One of the emerging technologies in construction is the development of ‘smart structures’ which have sensors which will allow more efficient, resilient and sustainable structures to be designed and constructed. This research ... -
Application of electrodialysis for nutrient recovery from Anaerobic digestate
(NUI Galway, 2023-03-30)Electrodialysis (ED) is an electro-driven membrane-based technology, which can separate ions from solutions with high efficiency. Recently, ED has been studied to recover nutrients, i.e., ammonium (NH4 +) and phosphate ... -
Application of electrodialysis into nutrient recovery and antibiotics removal for pig manure management
(NUI Galway, 2019-07-25)Animal manure should be regarded as a resource rather than a waste as it contains abundant nutrients (nitrogen and phosphorus) available for plants. Land spreading of animal manure is a common practice while it has to be ... -
Assessment and mitigation of forest clearfelling impacts on salmonid receiving waters
(2012-09-03)It was estimated that about 500,000 hectare (ha) of peatland was afforested between the 1950s and 1990s in the UK and 300,000 ha in Ireland. Many of these blanket peat forests are now reaching harvestable age and concerns ... -
Assessment of materials used in land drainage systems
(NUI Galway, 2023-08-15)Agricultural land drainage is one of a number of critical components to sustaining food production on poorly drained mineral soils. The key to efficient and consistent drainage system performance is an appropriate type and ... -
Assessment of slaughterhouse wastewater treatment by using intermittently-aerated sequencing batch reactors (IASBRs)
(2013-10-16)A large amount of slaughterhouse wastewater is generated during meat product manufacturing due to the cleaning process. It contains high concentrations of organic matter, oil and grease, and nitrogenous compounds (proteins ... -
Assessment of the impact of forestry on peatlands on the environment
(2012-12-19)Ireland's forest cover stands at approximately 10 %, or 700,000 ha, of the total surface area of the island and it is estimated that almost 60 % of this forestry is on peat. Forestry on peatland throughout the world is now ... -
Biosafety assessment during anaerobic co-digestion of food waste and pig manure
(NUI Galway, 2022-10-11)Antimicrobial resistance (AMR) spreading has been a public concern as it increases the mortality of infection, and some biowastes (such as pig manure, food waste and municipal waste sludges) have been reported as hotspots ... -
CAL4AHU - Calibration of air handling unit models for fault detection and diagnosis
(NUI Galway, 2021-02-08)A systematic methodology for the automated calibration of Air Handling Unit (AHU) computational models for use in Fault Detection and Diagnosis (FDD) is investigated that requires a minimum dataset and produces a trade-off ... -
Combined experimental testing and numerical modelling of a novel vertical axis tidal turbine
(NUI Galway, 2018-11-30)This research presents a study of a novel vertical axis tidal turbine (VATT) – the GKinetic turbine – using experimental testing of scale devices and numerical modelling. The primary aims of the thesis were: (1) to assess ... -
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 ... -
Cyclic loading tests on sandstone and limestone shale aggregates used in unbound forest roads.
(Construction and Building Materials, 2009-06-01)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. ... -
Deciphering anaerobic ethanol oxidation for better recovery of renewable energy from wastewater
(NUI Galway, 2024-03-28)Anaerobic digestion is a promising technology relying on complex microbial interactions to convert organics into methane, achieving sustainable energy recovery. Ethanol is an important low-molecular intermediate during ... -
Deep-retrofit decision-making support for achieving nearly zero-energy buildings with enhanced comfort
(NUI Galway, 2019-04-11)The emerging trends for deep-retrofit of existing buildings in Europe require formulation of strategies for nearly zero-energy buildings (nZEBs) and achieving benchmarks as outlined in the Energy Performance of Buildings ... -
The development of a high-resolution nested bridge hydraulic model
(NUI Galway, 2023-11-23)Traditionally, hydraulic modelling of bridges has been undertaken using one dimensional models like HEC-RAS. One-dimensional models simplify river channels using several cross sections along a river curve and strongly ... -
Development of a novel water quality index model using data science approaches
(NUI Galway, 2023-05-30)The thesis present the Irish Water Quality Index (IEWQI) model for assessing transitional and coastal water quality in an effort to improve the method and develop a tool that can be used by environmental regulators to abate ... -
Development of a standardised assessment methodology relating to flexibility analysis for demand response
