Collaborative learning is a key, and complementary, component of student-centred enquiry-based pedagogy. Today, many educators understand that students learn effectively when working together with their peers to construct new knowledge. Many teachers are working to help their students develop such ability. Teachers do this to help students better understand the relevance of new content, connect new ideas into existing frameworks of understanding, and construct new neurological pathways and connect synapses in their brains. In addition, group learning has been shown to increase students’ critical thinking skills, creativity, collaborative behaviours, understanding of ethics, and the like. In the literature, attention has …
Analysis Of Wind Velocity And The Quantification Of Wind Turbulence In Rural And Urban Environments Using The Levy Index And Fractal Dimension, Jonathan Blackledge, Eugene Coyle, Niall Mccoy, Derek Kearney, Keith Sunderland, Thomas Woolmington
Analysis Of Wind Velocity And The Quantification Of Wind Turbulence In Rural And Urban Environments Using The Levy Index And Fractal Dimension, Jonathan Blackledge, Eugene Coyle, Niall Mccoy, Derek Kearney, Keith Sunderland, Thomas Woolmington
Articles
This paper is concerned with a quantitative and comparative analysis of wind velocities in urban and rural environments. It is undertaken to provide a route to the classification of wind energy in a rural and urban setting. This is a common problem and the basis of a significant focus of research into wind energy. In this paper, we use a non-Gaussian statistical model to undertake this task, and, through a further modification of the data analysis algorithms used, extend the model to study the effect of wind turbulence, thereby introducing a new metric for this effect that is arguably superior …
Examining The Role Of The University In Creating Jobs, Mike Murphy, Michael Dyrenfurth
Examining The Role Of The University In Creating Jobs, Mike Murphy, Michael Dyrenfurth
Articles
This paper begins by setting out the rationale for why today’s university must be involved with job creation in terms of institutional mission and global competitiveness. We present a review of recent literature, from both sides of the Atlantic, regarding universities, technology and science parks and job creation. Measuring the impact of university actions is reviewed in terms of general criteria, impact of incubators, and where jobs are being created. A case study of Silicon Valley is reviewed as well as a discussion of roles that government might play. The paper concludes with the presentation of findings from the literature …
Natural Convection In An Internally Finned Phase Change Material Heat Sink For The Thermal Management Of Photovoltaics, M. J. Huang, P. C. Eames, Brian Norton, N. J. Hewitt
Natural Convection In An Internally Finned Phase Change Material Heat Sink For The Thermal Management Of Photovoltaics, M. J. Huang, P. C. Eames, Brian Norton, N. J. Hewitt

Elevated operating temperatures reduce the solar to electrical conversion efficiency of building integrated photovoltaic devices (BIPV). Phase change materials (PCM) can be used to passively limit this temperature rise although their effectiveness is limited by their low thermal conductivities and by crystallization segregation during solidification. This paper presents an experimental evaluation of the effects of convection and crystalline segregation in a PCM as a function of efficiency of heat transfer within the finned PV/PCM system. The thermal performances of bulk PCM with crystallization segregation for different internal fin arrangements are presented. It is noted that the addition of internal fins …

The EU-US Agreement through the Atlantis Programmes supports consortia of higher education and training institutions working together at undergraduate or graduate level to improve their educational services, to compare and modernise curricula and to develop joint study programmes with full recognition of credits and qualifications. The EU-US Atlantis Programme funds innovative projects across three strands: mobility projects, double or joint “transatlantic degrees” for students in the EU and US and policy-oriented measures. The main focus of activities must be on transatlantic rather than intra-European or intra-American interactions. Funded activities, such as the development of curricula, joint study programmes, exchanges and …
An International Comparison Of Engineering Programs In Their Emphases And Professional Skills Development, Gul Okudan Kremer, Mike Murphy, Brian Bowe
An International Comparison Of Engineering Programs In Their Emphases And Professional Skills Development, Gul Okudan Kremer, Mike Murphy, Brian Bowe
Articles
In the face of grand challenges for engineering, several efforts have been undertaken to identify the vision for what we should expect from our undergraduate engineering students. For example, one of the significant reports indicates that our graduates should aspire “to have the ingenuity of Lillian Gilbreth, the problem solving capabilities of Gordon Moore, the scientific insight of Albert Einstein, the creativity of Pablo Picasso, the determination of the Wright brothers, the leadership abilities of Bill Gates, the conscience of Eleanor Roosevelt, the vision of Martin Luther King, and the curiosity and wonder of our grandchildren.” This statement implies that …

Articles
Globalization, competitiveness, and innovation are frequently employed themes as governments, business and industry and universities attempt to respond to the challenges facing them. Clearly business as usual is not likely to be successful in the future. One strategic response for universities has been a significant impetus – in many parts of the world – towards dual, joint or concurrent degree programs involving international partners. It is perhaps not surprising that engineering is among the disciplines that make most use of international collaboration but it seems that engineering technology programs do not yet participate as extensively in this aspect of international …
Tempo Detection Using A Hybrid Multi-Band Approach, Mikel Gainza, Eugene Coyle
Tempo Detection Using A Hybrid Multi-Band Approach, Mikel Gainza, Eugene Coyle
Articles
In this paper, a novel tempo detection system is presented, which suggests the use of a hybrid multiband decomposition. The model tracks the periodicities of different signal property changes that manifest within different frequency bands by using the most appropriate onset/transient detectors for each frequency band. In addition, the proposed system applies a novel method to weight tempo candidates. Each contribution is evaluated by comparing the presented system against existing approaches using three different databases that comprises 1638 songs. These databases include the two publicly available database of songs used in the tempo evaluation contest of ISMIR 2004. These songs …
Validated Real-Time Energy Models For Small-Scale Grid-Connected Pv-Systems, Lacour Ayompe, Aidan Duffy, Sarah Mccormack, Michael Conlon
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 …

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

Microwave-Assisted Synthesis Of Zno Micro-Javelins, Suresh Pillai, Declan Mccormack, John M. Kelly, Sibu C. Padmanabhan
Articles
The microwave (MW)-assisted formation of ZnO micro-javelins from zinc nitrate and urea in aqueous solution is described. The particles (named as ‘micro-javelins’ because of their high aspect ratio and needle-like tips) grow hexagonally with well-defined facets in the h0110i direction and pointed tips in (0001) direction. Powder X-ray diffraction patterns show the appearance of a strikingly dominant (1000) orientation. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) investigations reveal the morphological evolution of these hexagonal ZnO particles with time. The effect of precursor concentrations, counterion type andMWirradiation power and their consequent influence on pH and Zn2+ ion concentration are …
Extended Nonnegative Tensor Factorisation Models For Musical Sound Source Separation, Derry Fitzgerald, Matt Cranitch, Eugene Coyle
Extended Nonnegative Tensor Factorisation Models For Musical Sound Source Separation, Derry Fitzgerald, Matt Cranitch, Eugene Coyle
Articles
Recently, shift-invariant tensor factorisation algorithms have been proposed for the purposes of sound souce separation of pitched musical instruments. However, in practice, existing alogorithsm require the use of log-frequency spectrograms to allow shift invariance in frequency which causes problems when attempting to resynthesise the separated sources. Further, it is difficult to impose harmonicity constraints on the recovered basis functions. This paper proposes a new additive synthesis-based approach which allows the use of linear-frequency spectrograms as well as imposing strict harmonic constraints, resulting in an improved model. Futher, these additional constraints allow the addition of a source filter model to the …
The New Engineer: Between Employability And Social Responsibility, Eddie Conlon
The New Engineer: Between Employability And Social Responsibility, Eddie Conlon
Articles
The reasons behind the demand for what is sometimes called the New Engineer are critically examined and it is argued that a focus on employability alone is not sufficient to prepare socially responsible engineers. By examining issues around work organisation and sustainability it is proposed that engineers need to understand the wider social context in which they work. It is argued that the focus of ethics education should be broadened to focus on the social structure and the way it both enables and constrains socially responsible conduct. There is a call to refocus engineers’ attitudes towards the systems of regulation …
Photopolymer Diffractive Optical Elements In Electronic Speckle Pattern Shearing Interferometry, Emilia Mihaylova, Izabela Naydenova, Barry Duignan, Suzanne Martin, Vincent Toal
Photopolymer Diffractive Optical Elements In Electronic Speckle Pattern Shearing Interferometry, Emilia Mihaylova, Izabela Naydenova, Barry Duignan, Suzanne Martin, Vincent Toal
Articles
In this paper we present an electronic speckle pattern shearing interferometer using a photopolymer diffractive optical element in the form of a holographic grating, in combination with a ground glass to shear the images. The sheared images on the ground glass are further imaged onto a CCD camera. The distance between the grating and the ground glass can be used to control the shear and to vary the sensitivity of the system. The direction of sensitivity is easily controlled by rotation of the diffraction grating around its normal. Introducing photopolymer holographic gratings in ESPSI gives the advantage of using high …
Holographic Patterning Of Acrylamide-Based Photopolymer Surface, Izabela Naydenova, Emilia Mihaylova, Suzanne Martin, Vincent Toal
Holographic Patterning Of Acrylamide-Based Photopolymer Surface, Izabela Naydenova, Emilia Mihaylova, Suzanne Martin, Vincent Toal
Articles
The patterning of an acrylamide-based photopolymer surface by holographic recording is studied. The patterns are induced by light alone and no post-processing is required. Periodic surface modulation is observed in addition to a volume phase grating. An investigation has been carried out using white light interferometry into the dependence of the amplitude of the photo induced surface relief modulation on the spatial frequency, intensity of recording and sample thickness. The observed dependencies indicate that the diffusion of material during the holographic recording plays a major role in surface relief formation. The possibility for inscription of surface relief patterns opens the …

Shadow Casting Phenomena At Newgrange, Frank Prendergast
Shadow Casting Phenomena At Newgrange, Frank Prendergast
Articles
A digital model of the Newgrange passage tomb and surrounding ring of monoliths known as the Great Circle is used to investigate sunrise shadow casting phenomena at the monument. Diurnal variation in shadow directions and lengths are analysed for their potential use in the Bronze Age to indicate the passage of seasonal time. Computer-aided simulations are developed from a photogrammetric survey to accurately show how three of the largest monoliths, located closest to the tomb entrance and archaeologically coded GC1, GC-1 and GC-2, cast their shadows onto the vertical face of the entrance kerbstone, coded K1. The phenomena occur at …
