Weathering and consolidation trials on sandstones used in Irish Monuments.
(LNEC, Laboratorio Nacional de Engenharia Civil, Lisbon, 2008)The objective of this study was to assess the efficiency of consolidant treatments in improving the durability of Irish sandstones, particularly sandstones used in national monuments at Cashel, Clonfert and Clonmacnoise. ... -
A study of the durability of OPC vs. GGBS concrete on exposure to silage effluent
(American Society of Civil engineers, 2008)Ordinary portland cement (OPC) has been traditionally used in the construction of concrete silos in Ireland. However, the aggressive nature of the effluent produced by silage leads to severe degradation of the concrete. ... -
A petrographic study of mortar hydraulicity.
(2008)The nature of the binder determines the mortar cohesiveness and its intrinsic bond, therefore it greatly impacts its physical properties and durability. In a binder, the hydrated material is mainly responsible for the ... -
Salt Weathering on Buildings and Stone Sculptures.
(2008)This paper concentrates in the phenomenon of sulfate formation within an old cement paste dating from c.1878, leading to damage of the mortar and its adjacent masonry. Samples of mortar and salt efflorescence were taken ... -
Determination of brick provenance and technology using analytical techniques from the physical sciences
(Blackwell, 2006)This work applies established analytical techniques of physical sciences to Irish brick in order to gather evidence of ceramic technologies, provenance and sources of raw materials. Petrographic microscopy, X-ray diffractometry ... -
The provision of on street passenger information via real time passenger information; a case study of Dublin
(IEE,, 2004)In June 2001 Dublin Bus introduced a real time passenger information (RTPI) system on the first of its eleven quality bus corridors (QBC), on the Lucan QBC. The introduction is part of a three-year pilot programme called ... -
Design and manufacture of surface acoustic wave sensors for real-time weigh-in-motion.
(IEEE, 2005)This paper presents the design and manufacture of surface acoustic wave (SAW) strain sensors which can be produced in a university environment. These sensors can be interrogated wirelessly and operated without a power ... -
Urban freight in Dublin city centre: survey analysis and strategy evaluation
(National Academy of Sciences, 2005)Findings are presented from a study evaluating sustainable freight distribution in the city center of Dublin, Ireland, particularly focusing on urban distribution centers (UDCs) and managing the last mile of deliveries. A ... -
Travel behaviour and transportation needs of the disabled: case study of some categories of disability in Dublin, Ireland
(National Academy of Sciences, 2005)The arguments in defence of poor attention to those with disabilities in terms of offering equal opportunities to transportation options tend to centre on the high cost of provision or improvement in facilities. The paper ... -
Environmental and social transport costs: a case study of Ireland
(Transportation Research Board of the National Academies, 2005)The aim of the EU funded UNITE research project was to provide information about the costs, benefits and revenues of all transport modes including environmental and social costs. The project involved compiling accounts ... -
A model for development of optimised feeder routes and coordinated schedules: a genetic algorithms approach
(Elsevier, 2006)Many attempts have been made to solve bus route network design problems by splitting it in two stages, one for routing and the other for scheduling. Some researchers have made attempts to solve network design problems ... -
The relationship between geometric design consistency and safety on rural single carriageways
(Association for European Transport, 2007)Rural single carriageways in Ireland tend to fall below current design standards and have higher accidents rates (per vehicle kilometre) than roads designed to modern standards. Resources are not available to improve ... -
Factors influencing preferences for real-time public transport information
(Association for European Transport, 2007)This paper presents the results of a study undertaken in Dublin, to ascertain preferences for real-time public transport information. This study examines the need for public transport information across three stages of ... -
An examination of the public transport information requirements of users
(IEEE Intelligent Transportation Systems Society, 2007)This paper focuses on the provision of public transport information in Dublin, Ireland. It examines both existing and potential methods of accessing information, with particular focus on the implementation of various ... -
Time-series modelling for forecasting vehicular traffic flow in Dublin
(2005)The traffic flow at an arterial intersection in a congested urban transportation network in the city of Dublin is modelled in this paper. Three different time-series models, viz. random walk model, Holt-Winters? ... -
Design of feeder route network using combined genetic algorithm and specialised repair heuristic
(National Center for Transit Research (NCTR), 2007)In metropolitan cities an efficient integrated public transportation system is unavoidable in order to restrict unsustainable growth of private and intermediate transport modes. Well designed feeder routes and ... -
Wavelet-Bayesian hierarchical stochastic model for short-term traffic flow at noncritical junctions
(2008)In ITS (Intelligent Transportation System) equipped urban transportation systems noncritical junctions are often ignored in short-term traffic condition prediction algorithms as the traffic data collection systems in ... -
Measuring risk of attack on bus networks
(2008)Public transport systems are at risk from attacks as they are open, dynamic systems carrying large numbers of people. Although attacks have been carried out on public transport since the 1920?s, the nature of attacks has ...
