Climate Change And The Conservation Of Archaeological Sites: A Review Of Impacts Theory, Caithleen Daly
Climate Change And The Conservation Of Archaeological Sites: A Review Of Impacts Theory, Caithleen Daly
Articles
This article identifies the current state of knowledge in the literature regarding the possible impacts of future climatic change on archaeological sites and ensembles. Drawing on the literature review a matrix of potential impacts is collated to provide a simplified overview. This theoretical ‘menu’ is then tested by applying it to a vulnerability assessment of the World Heritage site of Skellig Michael in Ireland. The case study results reveal some knowledge gaps, particularly in regard to the impacts of climate change on buried archaeological remains.
The Potential For Indicators In The Management Of Climate Change Impacts On Cultural Heritage, Caithleen Daly
The Potential For Indicators In The Management Of Climate Change Impacts On Cultural Heritage, Caithleen Daly
Conference papers
The global scale and unpredictable nature of climate change impacts on cultural heritage poses a challenge for conservation management. This article explores the potential of indicators as an aid for decision makers in the heritage sector. The author proposes a new indicator tool for addressing long-term stone recession impacts that may be related to climate change. The indicator is being installed at two World Heritage sites in Ireland but no results are available. The prototype was developed during doctoral research at the Technological University of Dublin.
A Stochastic Model For Wind Turbine Power Quality Using A Levy Index Analysis Of Wind Velocity Data, Jonathan Blackledge, Eugene Coyle, Derek Kearney
A Stochastic Model For Wind Turbine Power Quality Using A Levy Index Analysis Of Wind Velocity Data, Jonathan Blackledge, Eugene Coyle, Derek Kearney
Conference papers
The power quality of a wind turbine is determined by many factors but time-dependent variation in the wind velocity are arguably the most important. After a brief review of the statistics of typical wind speed data, a non- Gaussian model for the wind velocity is introduced that is based on a Levy distribution. It is shown how this distribution can be used to derive a stochastic fractional diusion equation for the wind velocity as a function of time whose solution is characterised by the Levy index. A Levy index numerical analysis is then performed on wind velocity data for both …
An Analysis Of The Mortality Risks Associated With Heat And Heat Waves In Ireland, To Assist In Planning For Climate Change, Mathilde Pascal
An Analysis Of The Mortality Risks Associated With Heat And Heat Waves In Ireland, To Assist In Planning For Climate Change, Mathilde Pascal
Doctoral
Although extreme temperatures have not been identified as a major cause of mortality in Ireland, climate change calls for an evaluation of the past, present and future health risks associated with heat and heat waves. The health impacts of heat were investigated using mortality and temperature data for the period 1981-2003. Data were aggregated in urban areas (Dublin, Cork, Drogheda, Arklow, Dundalk, Galway, Limerick, Waterford and Wexford) and rural areas. Seven heat waves were identified between 1981 and 2003, corresponding to 254 excess deaths (197 in rural areas, and 57 in urban areas). A major episode was observed in rural …
Stochastic Hybrid Embodied Co2-Eq Analysis: An Application To The Irish Apartment Building Sector, Adolf Acquaye, Aidan Duffy, Biswajit Basu
Stochastic Hybrid Embodied Co2-Eq Analysis: An Application To The Irish Apartment Building Sector, Adolf Acquaye, Aidan Duffy, Biswajit Basu
Articles
Although embodiedCO2-eq analysis has seen recent developments as evident in the establishment of the ISO14040 and 14044 LCA standards, it is recognized that due to weaknesses in gathering data on product-related emissions,embodiedCO2-eq values are probabilistic. This paper presents a stochastic analysis of hybrid embodied CO2-eq in buildings to account for this weakness in traditional methods and, by way of example, applies it to an Irish construction-sector case study. Using seven apartment buildings, 70,000 results are simulated with Monte Carlo analysis and used to derive probabilistic and cumulative embodied CO2-eq intensity distributions for apartment buildings in Ireland. A Wakeby distribution with …
Identification Of ‘Carbon Hot-Spots’ And Quantification 1 Of Ghg Intensities In The Biodiesel Supply Chain Using Hybrid Lca And Structural Path Analysis, Adolf Acquaye, Thomas Wiedmann, Kuishang Feng, Robert Crawford, John Barrett, Johan Kuylenstierna, Aidan Duffy, Lenny Koh, Simon Mcqueen-Mason
Identification Of ‘Carbon Hot-Spots’ And Quantification 1 Of Ghg Intensities In The Biodiesel Supply Chain Using Hybrid Lca And Structural Path Analysis, Adolf Acquaye, Thomas Wiedmann, Kuishang Feng, Robert Crawford, John Barrett, Johan Kuylenstierna, Aidan Duffy, Lenny Koh, Simon Mcqueen-Mason
Articles
It is expected that biodiesel production in the EU will remain the dominant contributor as part of a 10% minimum binding target for biofuel in transportation fuel by 2020 within the 20% renewable energy target in the overall EU energy mix. Life cycle assessments (LCA) of biodiesel to evaluate its environmental impacts have, however, remained questionable, mainly because of the adoption of a traditional process analysis approach resulting in system boundary truncation and because of issues regarding the impacts of land use change and N2O emissions from fertiliser application. In this study, a hybrid LCA methodology is used to evaluate …
Embodied Emissions Abatement: A Policy Assessment Using Stochastic Analysis, Adolf Acquaye, Aidan Duffy, Biswajit Basu
Embodied Emissions Abatement: A Policy Assessment Using Stochastic Analysis, Adolf Acquaye, Aidan Duffy, Biswajit Basu
Articles
Policymakers traditionally focus on regulating operational energy use in buildings, ignoring other life cycle components such as embodied energy even though this may account for a significant portion of life cycle emissions. Data relating to embodied energy and emissions in buildings is limited. However, stochastic techniques can be used to estimate the distribution of such emissions from buildings. This helps policymakers identify which instruments are appropriate for achieving emissions reductions. A primary aim of this paper is to demonstrate this approach using a sample of apartment buildings in Ireland. A Monte-Carlo simulation suggests that the average probability distribution of embodied …

A Practical Photoelectrochemical Cell Using Nonprecious Metal Electrodes, Patrick Enright, Tony Betts, John Cassidy
Articles
Abstract: Photoelectrochemical cells (PECs) can be used to harvest light from the oxidation of dissolved organic matter. Similar to fuel cells but requiring light to operate, PECs contain a light assisted electrode that oxidises electron rich materials (anode); these electrons then flow to a typically Pt cathode where O2 is normally the electron acceptor. In this work a PEC cell containing inexpensive materials was shown to (a) mineralise typical organic compounds present in waste water and (b) produce electricity from their decomposition. The PEC cell consisted of a TiO2 coated conducting ink anode exposed to a light source, …
An Investigation Into The Design, Development And Testing Of A Tool To Improve The Accessibility Of Access Information For People With Disabilities, Susan Codd
Masters
Independent access for all to the built environment is one of the most basic of human rights. It provides social inclusion, integration and acceptance in communities. People with disabilities often encounter barriers to such access, barriers that can discriminate and marginalise to the extent that it prohibits independent living. Visiting the built environment becomes a lottery whereby inaccessible features may be present around every corner. People with disabilities deserve more than operating on a system of chance; they require a tool to make an informed decision prior to embarking on a journey. However in order to provide such information three …
