(Elsevier, 2007-01)This research develops a weighted integer goal-programming model for prioritising railway projects for investment. The goal of the model is to prioritise the identified projects for investment while maximising the objectives ...
-
(Optical Society of America, 1999-08-01)The fractional Fourier transform (FRT) is known to be optically implementable with use of a medium with a perfect radial quadratic-index profile. Using the quantum-mechanical operator formalism, we examine the effects ...
-
(Wiley, 2009-08-01)Biofilm-related research using 96-well microtiter plates involves static incubation of plates indiscriminate of environmental conditions, making oxygen availability an important variable which has not been considered to ...
-
(2005-05)A systematic assessment scheme for determining the alkali reactivity of aggregates has been developed for international use. Expansion tests were conducted on Irish aggregates. Aggregates were subjected to a sequence of ...
-
(ENEA, 2010)The assessment of site-specific bridge traffic loading using WIM data is a critical feature of minimizing the cost of rehabilitation and replacement for bridge stock. For short- to medium-span bridges, it is often assumed ...
-
(CRC Press, 2012-07-08)This paper summarises the developments in the dynamic response of bridges to traffic loading based on a large amount of simulations and field tests carried out within the 6th EU framework ARCHES (2006-2009). When assessing ...
-
(Elsevier Science, 1996)This paper highlights areas of inaccuracy in current modelling techniques for bridge decks with wide cantilevers. A 3-D grilllage model known as the upstand grillage is assessed by comparing its behaviour with that of a ...
-
(Optical Society of America, 2005-09-10)Holography has been of increasing interest in recent years, with developments in many areas such as data storage and metrology. Photopolymer materials provide potentially good materials for holographic recording, as they ...
-
(Elsevier, 2007-05)This paper presents a novel approach to the reduction of short-span bridge dynamic responses to heavy vehicle crossing events. The reductions are achieved through adjustment of the vehicle suspension damping coefficient ...
-
(Optical Society of America, 2010-04-01)The linear canonical transform may be used to simulate the effect of paraxial optical systems on wave fields. Using a recent definition of the discrete linear canonical transform, phase space diagram analyses of the ...
-
(Elsevier, 2011-10)This paper examines whether regional characteristics can have a significant impact on the engine sizes of the car fleet in Ireland. Disposable income is found to be the dominant factor in determining the purchase ...
-
(Elsevier, 2013-01)Due to a lack of indigenous fossil energy resources, Ireland's energy supply constantly teeters on the brink of political, geopolitical, and geographical unease. The potential risk to the security of the energy supply ...
-
(American Society of Civil Engineering (ASCE), 2010-06)Despite billions of dollars of annual exposure from claims and litigation related to construction-induced damage, there are no quantitatively based, agreed upon standards or procedures as to what constitutes due diligence ...
-
(Elsevier, 2004-10-29)The fate of ammoniacal-nitrogen (NH4-N) was studied in a lab-scale downflow reed bed system treating an artificial landfill leachate. Individual reed beds were submerged by the leachate, then drained and rinsed by tap ...
-
(Elsevier, 2011-04)This study investigated the glyphosate adsorption by water treatment residual (termed as alum sludge) in dewatered form (DAS) and liquid form (LAS). Batch adsorption tests were carried out with DAS at different pH, particle ...
-
(Taylor & Francis, 2001-10-05)This report gives results of some new studies performed to validate the European road traffic load model proposed by the Eurocode EC1. Weight in motion has developed greatly in the last ten years and confidence in the ...
-
(Taylor & Francis, 2008-06)The purpose of this study is to optimize adsorption conditions of powdered alum sludge (PAS) as low-cost adsorbent for the removal of three P-species (ortho-P, poly-P and organic-P) from wastewater using the response surface ...
-
(Institution of Civil Engineers, 2012-01)Practising engineers in the Dublin, Ireland, area have much experience in dealing with the boulder clay which underlies much of the city. However, significant deposits of estuarine soils, some of them soft, exist along the ...
-
(Institution of Civil Engineers, 2012-01)A good number of deep excavations have been recently completed in Dublin Boulder Clay, Ireland. These have included propped walls up to 25 m deep and permanent cantilevers 7.5 m high. Experience elsewhere in the world was ...
-
(Taylor & Francis, 2007-10)The adsorption equilibrium of a wide range of phosphorus species by an aluminium-based water treatment sludge (Al-WTS) was examined in this study. Four kinds of adsorption-isotherm models, namely Langmuir, Freundlich, ...
