(Elsevier, 2005-01-26)This study investigated the efficiency of a four-stage tidal flow constructed wetland system for the removal of organic matter and ammoniacal-nitrogen from diluted piggery wastewater. The results demonstrated that the ...

Enhancement factors for the vertical response of footbridges subjected to stochastic crowd loading (Elsevier, 2012-07)The vertical acceleration response of a hypothetical footbridge is predicted for a sample of single pedestrians and a crowd of pedestrians using a probabilistic approach. This approach uses statistical distributions to ...
-
(Copernicus Publications on behalf of the European Geosciences Union, 2012-07-20)A framework of guiding recommendations for effective pre-flood and flood warning communications derived from the URFlood project (2nd ERA-Net CRUE Research Funding Initiative) from extensive quantitative and ...
-
(Elsevier, 2010-12-15)Excess phosphorus (P) in wastewaters promotes eutrophication in receiving waterways. A cost-effective method such as use of novel low-cost adsorbents for its adsorptive removal would significantly reduce such impacts. Using ...
-
(Civil-Comp Press, 2009-09)In this study two different models have been developed and tested with data from 55 hydrometric stations in the Shannon River Basin in Ireland for estimating the location and the scale parameters of the EV1 distribution ...
-
(CRC Press, 2012-07-08)This paper considers the problem of assessing traffic loading on road bridges. A database of European WIM data is used to determine accurate annual maximum distributions of load effect. These in turn are used to find the ...
-
(Elsevier, 2009-10)Non-equilibrium molecular dynamics (NEMD) simulations have been performed for static electric fields for a range of positively charged spherical rutile–titania nanoparticles with radii of 1.5 to 2.9 nm for two different ...

-
(University College Dublin. Centre for Water Resources Research, 2006-09)Phosphorous has been implicated as the primary cause of the deterioration of surface water quality in Ireland. Extensive water quality surveys revealed that diffuse sources (runoff and subsurface flows) from agricultural ...

(American Society of Civil Engineering (ASCE), 2006-04)Falling trees pose a great hazard to the safe and uninterrupted use of the road transportation system, during storm events. The present process of manually identifying potentially hazardous trees is laborious and inefficient. ...
-
(Taylor & Francis, 2009-02)In the present work, homogenous (photo-Fenton) and heterogeneous photo-assisted systems (Fenton/TiO2/UV, Fenton/ZnO/UV and Fenton/TiO2/UV/Air) were investigated for the treatment of a diesel-oil wastewater emulsion. The ...
-
(Elsevier, 2012-05-25)The photoactivity of both un-doped and carbon-doped titanium dioxide (TiO2) coatings has been widely reported. In this paper, the use of a microwave plasma as a novel oxidation treatment for the fabrication of these coatings ...
-
(European Geosciences Union, 2009-04)The Shannon river basin is the largest in Ireland and it encompasses a number of urban and rural towns. The water of this river provides the demand for drinking, agriculture, ecology, industry, etc. Therefore it is essential ...
-
Evaluation of the odour reduction potential of alternative cover materials at a commercial landfill (Elsevier, 2010-02)The availability of virgin soils and traditional landfill covers are not only costly and increasingly becoming scarce, but they also reduce the storage capacity of landfill. The problem can be overcome by the utilisation ...
-
(Wiley and Chartered Institution of Water and Environmental Management (CIWEM), 2010-03)This paper summarises the findings of a study to evaluate the use in Ireland of the different flood estimation methodologies that can be applied to urban or urbanising catchments. The study, undertaken as part of the Office ...
-
(Inderscience Enterprises, 2010-04-24)A new evolutionary design tool is presented, which uses shape grammars and a grammar-based form of evolutionary computation, grammatical evolution (GE). Shape grammars allow the user to specify possible forms, and GE allows ...
-
(IOS, 2012)Structures include elements designated as load bearing and non-load bearing. While non-load bearing elements, such as facades and internal partitions, are acknowledged to add mass to the system, the structural stiffness ...
-
(2008-12)Accurate determination of shear wave arrival time using bender elements may be severely affected by a combination of near field effects and reflected waves. In most cases, the nearfield effect masks the first arrival and ...
