National Centre for Water and Wastewater Research and Demonstration
(EPA: STRIVE Report 78, 2010)Decentralised wastewater treatment systems for small towns (200 2,000 PE) often have different design requirements to those of systems for larger conurbations even though the treatment process technologies may be similar. ... -
The nature of stable char radicals: An ESR and DFT study of structural and hydrogen bonding requirements
(Wiley, 2018-06-28)Pyrolysis is a promising way to convert biomass into fuels and chemicals. This reaction is complex and inevitably involves a cascade of radical reactions that lead to char formation, in which some radicals become trapped ... -
Nested circulation modelling of inter-tidal zones: details of a nesting approach incorporating moving boundaries
(2010)Nested circulation models developed to date either exclude the flooding and drying process or prohibit flooding and drying of nested boundaries; they are therefore ill-suited to the accurate modelling of inter-tidal areas. ... -
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 ... -
Neural Network Approach to Predicting Stock Exchange Movements using External Factors
(2005)The aim of this study is to evaluate the effectiveness of using external indicators, such as commodity prices and currency exchange rates, in predicting movements in the Dow Jones Industrial Average index. The performance ... -
Neutrality through transcription and translation in genetic algorithm representation
(SciTePress Digital Library, 2012-10-05)This paper examines the use of the biological concepts of transcription and translation, to introduce neutrality into the representation of a genetic algorithm (GA). The aim of the paper is to attempt to identify problem ... -
Next Generation Face Tracking Technology Using AAM Techniques
(IEEE, 2007)This paper realizes an investigation of the active appearance model (AAM) techniques, with particular emphasis on problems related to the implementation of AAM in realtime face tracking applications for embedded systems. ... -
Nitrate removal rate, efficiency and pollution swapping potential of different organic carbon media in laboratory denitrification bioreactors.
(Ecological Engineering, 2012-01-01)Laboratory denitrifying bioreactors, which use an organic carbon (C) rich media to enhance microbial reduction of nitrate (NO3-) to nitrogen (N) gases, are used worldwide to protect surface and groundwater. To highlight ... -
Nitrification in a vertically moving biofilm system
(Elsevier, 2006-03)A laboratory continuous feed biofilm reactor, comprising a bulk fluid reactor, a biofilm plastic module, a feed tank, and pneumatic devices and controls, was operated for a total period of 257 days, including seeding time, ... -
Nitrification in a vertically moving biofilm system.
(Journal of Environmental Management, 2006-06-01)A laboratory continuous feed biofilm reactor, comprising a bulk fluid reactor, a biofilm plastic module, a feed tank, pneumatic devices and controls, was operated for a total period of 257 days, including seeding time, to ... -
Nitrogen-limitation-induced carbon and phosphorus fluxes in anaerobic/aerobic sequencing batch reactors
(Elseiver, 2010)Enhanced biological phosphorus removal (EBPR) has been applied widely in wastewater treatment plants. However, deterioration or failure of EBPR often happens because: (i) of the dominance of glycogen-accumulating organisms ... -
A novel BIM-based process workflow for building retrofit
(Elsevier, 2022-02-06)The European Union (EU) has developed policies aimed at accelerating the retrofit of existing buildings, with the vision of a decarbonised building stock by 2050. Retrofitting of existing buildings offers significant ... -
A novel hybrid coagulation-constructed wetland system for the treatment of dairy wastewater
(Elsevier, 2022-07-29)Constructed wetlands (CWs) are a cost-effective and sustainable treatment technology that may be used on farms to treat dairy wastewater (DWW). However, CWs require a large area for optimal treatment and have poor long-term ... -
A novel hybrid coagulation-intermittent sand filter for the treatment of dairy wastewater
(Elsevier, 2022-08-06)An intermittent sand filter (ISF) is a simple and cost-effective treatment method that may be adopted on farms to treat dairy wastewater (DWW). However, the use of ISFs has been limited due to the large area required for ... -
A novel hybrid filter for the treatment of septic tank effluent
(ASCE, 2006)Intermittent sand filtration is a common and effective method for treating septic tank effluent. However, if the loading rate is too high, clogging and ponding of the sand filter surface layer can occur due to the accumulation ... -

A novel image processing-based system for turbidity measurement in domestic and industrial wastewater
(IWA Publishing, 2018-01-19)Wastewater treatment facilities are continually challenged to meet both environmental regulations and reduce running costs (particularly energy and staffing costs). Improving the efficiency of operational monitoring at ... -
A novel machine learning based method for deepfake video detection in social media
(Institute of Electrical and Electronics Engineers (IEEE), 2021-05-12)With the advent of deepfake videos, video forgery has become a serious threat. Videos in social media are the most common and serious targets. There are some existing works for detecting deepfake videos but very few attempts ... -
