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 …

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 …

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 …
