Home Owners’ Attitudes, Perceptions And Willingness To Pay For Microgeneration Technologies, Marius Claudy, Aidan O'Driscoll, Aidan Duffy

Reports

This report evaluates Irish home owners’ perceptions, attitudes and willingness to pay (WTP) for microgeneration technologies, including photovoltaic (solar panels),[1] solar water heaters, micro wind turbines and wood pellet boilers.

The data presented in the report stem from two large-scale surveys, both designed by Technological University Dublin (DIT) and commissioned on behalf of Sustainable Energy Authority Ireland (SEAI) and DIT. The first study gathered data on Irish people’s general awareness of microgeneration technologies and was conducted in March 2009. The second and main survey targeted Irish home owners in order to understand their perceptions of and attitudes to microgeneration. …

Information Quality On The World Wide Web: A User Perspective, Jaikrit Kandari

Department of Industrial and Management Systems Engineering: Dissertations, Theses, and Student Research

Information Quality has emerged as an important measure for the success of Information Systems. At the same time the World Wide Web has established itself as the key infrastructure for information administration, exchange, and publication. Users are getting information from the web at the click of a button however they must filter sub-standard information before they can use quality content. Researchers have aimed to address this problem by suggesting various information quality frameworks. Research till date has seen twenty important Information Quality (IQ) frameworks emerge. These models though varied in their approach and application share a number of characteristics regarding …

Energy-Related Carbon Emissions In Ireland: Scenarios To 2020, Tadhg O'Mahony

Doctoral

The consumption of energy and related carbon emissions are a development challenge requiring analysis and policy insights. Current analysis of future change in Ireland relies on quantitative point forecasts within which accuracy is difficult to achieve. A scenario analysis approach has often been applied with the longer term but is also useful on shorter time-scales. This research applied a combination of decomposition analysis and scenario analysis to identify and analyse the driving forces of change in Ireland historically from 1990-2007 and in the future to 2020. The historical decomposition used the LMDI I technique and was further quantified to 2020 …

Validated Real-Time Energy Models For Small-Scale Grid-Connected Pv-Systems, Lacour Ayompe, Aidan Duffy, Sarah Mccormack, Michael Conlon

Articles

This paper presents validated real-time energy models for small-scale grid-connected PV-systems suitable for domestic application. The models were used to predict real-time AC power output from a PV system in Dublin, Ireland using 30-min intervals of measured performance data between April 2009 and March 2010. Statistical analysis of the predicted results and measured data highlight possible sources of errors and the limitations and/or adequacy of existing models, to describe the temperature and efficiency of PV-cells and consequently, the accuracy of power prediction models. PV-system AC output power predictions using empirical models for PV-cell temperature and efficiency prediction showed lower percentage …

Development Of A Framework For The Assessment Of The Role And Impact Of Technology On The Public Procurement Process: An Irish Health Sector Study, Paul Davis

Doctoral

This thesis sets out to examine how the role and impact of technology, in the context of the public procurement process, can be assessed by addressing it as a single bounded structural entity. The thesis specifically examines the procurement process in the Irish Health Sector. This thesis takes the view that context for the procurement process is critical and that adopting a structuration approach to the examination of the process allows for a greater understanding of the role of technology. The thesis is built around a thematic structure which examines the changing relationship between information technology systems and organisational structure. …

Towards An Integrated Approach To Engineering Ethics, Eddie Conlon

Conference papers

There is an increasing diversity in approaches to teaching engineering ethics due to increasing dissatisfaction with the dominant approach which uses case studies focused on moral dilemmas confronting individual engineers. There has been a demand for a greater consideration of the organisational and social context in which engineers work and for a shift in focus from micro ethics issues concerning individuals to macro issues of concern to the engineering profession. Further, there has been a demand that engineers focus on societal decision making about technology and their role in policy development. Drawing on the work of the American sociologist George …

Solar Cell Efficiency Enhancement Through Down-Shifting And Up-Converting Layers: The Ephocell Project: Luminescent Downshifting Quantum Yield Measurements, M. Kennedy, L. Aubouy, D. Gutiérrez-Tauste, A. Jorge, M. Faccini, G. Noriega, M. Di Lorenzo, M. Cocca, M. Avella, M. Errico, G. Gentile, John Doran, Brian Norton, S. Baluschev, J. Bistué Guardiola, A. Robles Molina, J. Puigdollers, C. Voz, S. Daren, F. Tsvetkov, A. Pashov

Conference Papers

Organic cells and dye-sensitized cells developed to-date have a narrow active absorption range, relative to the spectral range of the available solar resource. Their efficiency could be significantly enhanced through a process of down-shifting (DS) and up-conversion of non-absorbable photons converting them to photons better matching the spectral response of the particular solar cell. The DS molecules must exhibit a large Stokes shift and high luminescent quantum yield when incorporated in the downshifting polymer layer. In this paper, the QY of a downshifting Europium (III) complex in solution is determined using two distinct experimental techniques. The QY is measured for …

On The Use Of A Dynamic Hybrid Tempo Detection Model For Beat Tracking, Mikel Gainza

Conference papers

In this paper, an approach that estimates the times at which musical beats occur is presented. The system uses a hybrid multi-band decomposition in order to estimate the music tempo. Following this, beat events are tracked by using a dynamic programming approach, which is updated by using short time tempo estimates. The hybrid decomposition is used in order to calculate the tempo by using different onset detection functions in different frequency bands. In addition, a method that estimates which frequency bands provide reliable periodicities is also presented. The accuracy of the model is evaluated by comparing the presented system against …

Broadening Ethics Teaching In Engineering: Beyond The Individualistic Approach, Eddie Conlon, H. Zandvoort

Articles

There is a widespread approach to the teaching of ethics to engineering students in which the exclusive focus is on engineers as individual agents and the broader context in which they do their work is ignored. Although this approach has frequently been criticised in the literature, it persists on a wide scale, as can be inferred from accounts in the educational literature and from the contents of widely used textbooks in engineering ethics. In this contribution we intend to: (1) Restate why the individualistic approach to the teaching of ethics to engineering students is inadequate in view of preparing them …

Active Noise Barrier Minimizing Pressure Gradient, Carl Hart, Siu-Kit Lau

Durham School of Architectural Engineering and Construction: Faculty Publications

Minimization of the sound pressure field within the shadow zone of a noise barrier is achieved by reducing the pressure gradient along a line, at the top of a barrier, via active noise control. The noise control effectiveness of a barrier is increased by this strategy, especially for specific system configurations. The proposed method was evaluated by numerical simulation. Results indicate that system orientation has little effect on minimizing the pressure gradient at the top of the barrier when the error sensors are invisible to the primary noise disturbance. Highly effective control within the shadow zone and close to the …

Noise Propagation Through Open Windows Of Finite Depth Into An Enclosure, Caleb Sieck, Siu-Kit Lau

Durham School of Architectural Engineering and Construction: Faculty Publications

Predicting the insertion loss of an opening backed with an enclosed space is important for building noise control. Recent research in sound transmission through apertures of finite depth in infinite rigid baffles has included the effects of propagating and evanescent modes within the aperture in order to extend models to higher frequencies. The present study extends the model to the case of the aperture backed by a cavity as opposed to sound radiating into half-space. The role of coupling between the aperture modes, radiation modes, and cavity modes in the transmission was investigated. The results were compared to those of …

Quality Indicators For Engineering And Technology Education, Michael Dyrenfurth, Mike Murphy, Gary Bertoline

Conference papers

In recent years the development and use of university rankings, comparisons, and/or league tables has become popular and several methodologies are now frequently used to provide a comparative ranking of universities. These rankings are often based on research and publication activity and also not uncommonly focus on indicators that can be measured rather than those that should be measured. Further, the indicators are generally examined for the university as a whole rather than for university divisions, departments or programs. Implicit also is that placement in the rankings is indicative of quality. This paper provides an overview of the methodologies used …

Fusion Of Sources Of Evidence With Different Importances And Reliabilities, Florentin Smarandache, Jean Dezert, J.M. Tacnet

Branch Mathematics and Statistics Faculty and Staff Publications

This paper presents a new approach for combining sources of evidences with different importances and reliabilities. Usually, the combination of sources of evidences with different reliabilities is done by the classical Shafer’s discounting approach. Therefore, to consider unequal importances of sources, if any, a similar reliability discounting process is generally used, making no difference between the notion of importance and reliability. In fact, in multicriteria decision context, these notions should be clearly distinguished. This paper shows how this can be done and we provide simple examples to show the differences between both solutions for managing importances and reliabilities of sources. …
