Performance of novel media in stratified filters to remove organic carbon from lake water
(IWA Publishing, 2016-08-15)Disinfection by-products (DBPs) are an ever-increasing occurrence in water networks, particularly those which abstract water from peatland areas. Although much research has been carried out to discover novel methods to ... -
Permeability of carbon fibre PEEK composites for cryogenic storage tanks of future space launchers
(Elsevier, 2017-06-15)This work presents an experimental investigation into the permeability of carbon fibre (CF) polyetheretherketone (PEEK) for cryogenic storage tanks for space applications. The effects of cryogenic cycling, manufacturing ... -
Permeable and Non-reflecting Boundary Conditions in SPH
(Wiley, 2009-11)Inflow and outflow boundary conditions are essential for the application of computational fluid dynamics to many engineering scenarios. In this paper we present a new boundary condition implementation that enables the ... -
Permeable reactive interceptors: blocking diffuse nutrient and greenhouse gases losses in key areas of the farming landscape
(2014)Engineered remediation technologies such as denitrifying bioreactors target single contaminants along a nutrient transfer continuum. However, mixed contaminant discharges to a water body are more common from agricultural ... -
Phosphorus and nitrogen leaching from an organic and a mineral soil receiving single and split dairy slurry applications: A laboratory column experiment
(Springer, 2022-11-12)Purpose Intensification of farming means that organic soils, of low phosphorus (P) holding capacity, are being brought into production. Consequently, farmers may have to adjust their fertiliser application regimes to ... -
Phosphorus fertiliser equivalent value of dairy processing sludge-derived STRUBIAS products using ryegrass (Lolium perenne L.) and spring wheat (Triticum aestivum)
(Wiley, 2023-12-11)Struvite, biochar and ash products (collectively known as STRUBIAS) products derived from different waste streams are used as fertilisers in agriculture. Raw dairy processing sludge (DPS) shows promise as bio-based ... -
A physical corrosion model for bioabsorbable metal stents
(2014)Absorbable metal stents (AMSs) are an emerging technology in the treatment of heart disease. Computational modelling of AMS performance will facilitate the development of this technology. In this study a physical corrosion ... -
Physical experimental static testing and structural design optimisation for a composite wind turbine blade
(Elsevier, 2016-12-10)This study presents experimental testing on a 13 m long glass-fibre epoxy composite wind turbine blade. The results of the test were used to calibrate finite element models. A design optimisation study was then performed ... -
A physically-based constitutive model for high temperature microstructural degradation under cyclic deformation
(Elsevier, 2017-03-23)This paper presents a dislocation-mechanics cyclic viscoplasticity model which incorporates the key physical micro-mechanisms of strengthening and softening for high temperature deformation of 9Cr steels. In particular, ... -
A physically-based creep damage model for effects of different precipitate types
(Elsevier, 2016-10-13)The development of a new precipitate coarsening continuum damage mechanics (CDM) model to simulate the multi-precipitate strengthening mechanisms present in 9Cr steels under high temperature creep deformation is presented ... -
A physically-based high temperature yield strength model for 9Cr steels
(Elsevier, 2018-05-24)The strength of 9Cr steels, which is controlled by chemical composition and microstructure, evolves significantly under high temperature loading. This paper presents a temperature-independent, physically-based model for ... -
A physically-based method for predicting high temperature fatigue crack initiation in P91 welded steel
(Elsevier, 2021-08-27)A methodology is presented for physically-based prediction of high temperature fatigue crack initiation in 9Cr steels, with a focus on material inhomogeneity due to welding-induced metallurgical transformations. A modified ... -
Pile group settlement estimation: suitability of nonlinear interaction factors
(American Society of Civil Engineers, 2015-06)In this paper, predictions of pile settlement determined by appropriate superposition of two-pile interaction factors are compared with those computed from continuum analysis. A finite-element package is used in conjunction ... -
Pile groups under axial loading: an appraisal of simplified non-linear prediction models
(Thomas Telford (ICE Publishing), 2019-06-12)The settlement behaviour of vertically loaded pile groups has been the subject of an extensive body of research over the past two decades. In particular, this work has identified the over-conservatism associated with ... -
Player-Traced Empirical Cost-Surfaces for A* Pathfinding
(Eurosis, 2011)This paper discusses the use of empirical cost-surfaces derived from substantial amounts of player-traced movements in an online vehicular combat game, for the purposes of improving A* pathfinding by AI vehicles. The ... -
A Pleistocene deposit preserved in deep karst at Coolough, County Galway, western Ireland
(John Wiley and Sons, 2020-11-05)Buried karst features result from a complex interplay between carbonate bedrock and structural geology. The enhancement of carbonate aquifers through this interplay creates hydrogeologically complex subsurface drainage ... -
Polarity assessment of thermoresponsive poly(NIPAM-co-NtBA) copolymer films using fluorescence methods.
(Springer, 2010)The in-situ, non-contact, and non-destructive measurement of the physicochemical properties such as the polarity of thin, hydrophilic polymer films is desirable in many areas of polymer science. Polarity is a complex factor ... -
A porosity-based corrosion model for alkali halide ash deposits during biomass co-firing.
(American Chemical Society, 2015-04-24)This paper presents a physics-based model to describe accelerated corrosion because of alkali-halide-containing deposits, which form on superheater tube walls during biomass co-firing. Increased rates of corrosion during ...
