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 …

Digital Supply Chains: Towards A Framework For Software Distribution, Colm Ryan, Claudia-Maria Wagner, Edward Sweeney, Emilio Esposito, Pietro Evangelista

Conference papers

This paper assesses the effect of non-physicality of a digital product - software - on SCM practice. A number of in-depth, one-on-one interviews were held in 8 software companies that predominantly supply to enterprise customers on a global scale. The aim was to explore distribution challenges within software supply chains and how companies are addressing these challenges. The research has identified three different classes of software distribution models: One, which tends to rely on traditional physical infrastructures and paradigms, and two others that better exploit the properties of the digital products.

Implications Of Philosophy For Engineering And Engineering Technology Bachelors Programs, Michael Dyrenfurth, Mike Murphy, William Grimson

Conference papers

This paper raises the question: What is philosophy and then, after describing its branches and school, it extends the definitions to implications for the practice of engineering and engineering technology education. It folds the definitions against the work of engineering faculty. The latter was described as including curriculum development, teaching, mentoring/advising, research/scholarship, and engagement. Sample codes of ethics are shared for engineering technology students and professionals.

It is insider research and this paper identifies and examines barriers and enablers to …

The Role Of 3pls Internet Technology In Supporting Extended Enterprise: An Exploratory Survey, Pietro Evangelista, Emilio Esposito, Edward Sweeney, Erica Staller

Conference papers

It is well accepted that ICT and Internet technology have the potential to facilitate firms’ innovation processes as it offers new and more effective support to conduct business operations. This is particularly true in the context of Extended Enterprise (EE) concept where new technologies are critical in ensuring the effective integration of physical and information flows among participating companies (Dresner et al., 1999). The role of third party logistics providers (3PLs) in logistics outsourcing has evolved along the last few years (McKinnon, 1999). Such companies are transforming their business configuration from simple transport service providers to supply chain integrators. Internet …

An Integrated Approach To The Teaching Of Numerical Methods To Engineering Students, Garrett Keane, Michael Carr, Patrick Carroll

Conference papers

In Technological University Dublin, historically, numerical methods were taught to engineering students using a format of traditional mathematics lectures, to a large class group consisting of students from five different engineering disciplines, complemented by small class tutorials. Assessment was by a single, written exam only.

In order to improve the overall effectiveness of the students’ learning experience, it was deemed beneficial to also introduce practical computing classes in which the students would be required to apply the general mathematical methods covered in lectures to discipline-specific examples.

Three different practical computing assignments were devised for the students to undertake, and 20% …

Musical Source Separation Using Generalised Non-Negative Tensor Factorisation Models, Eugene Coyle, Derry Fitzgerald, Matt Cranitch

Conference papers

A shift-invariant non-negative tensor factorisation algorithm for musical source separation is proposed which generalises previous work by allowing each source to have its own parameters rather a fixed set of parameters for all sources. This allows independent control of the number of allowable notes, number of harmonics and shifts in time for each source. This increased flexibility allows the incorporation of further information about the sources and results in improved separation and resynthesis of the separated sources.

Philosophy Matters In Engineering Studies, William Grimson, Mike Murphy, Steen Hyldgaard Christensen, Erik Erno-Kjolhede

Conference papers

This article explores the rationale for including in an integrated five-years Masters Engineering programme liberal arts subjects, in particular Philosophy and the History of Science and Technology. We argue that the tools of philosophy should be used to provide additional insight into how engineering was and is 'performed'. We first review the challenge, next we present some results of an empirical case study carried out at AU-IBT in Denmark. The purpose of the case study was to examine a sample of engineering teachers´ attitudes towards the relevance and scope of liberal arts subjects for engineering students. Finally we conclude with …

Responses Of Engineering Students To Lectures Using Powerpoint, Aidan O'Dwyer

Conference papers

This contribution reports on, reflects on and evaluates engineering students responses to the use of PowerPoint in a lecture environment, compared to a more traditional lecturing approach. The contribution concludes that, on average, students value PowerPoint based lectures both as a means of better understanding the material and for the mediums structural and organisational advantages. Students also strongly favour the PowerPoint lectures being available on-line and that a paper copy of the PowerPoint presentation be distributed at the lecture.

Integrating Engineering Ethics And Research Skills In A First Year Programme, Eddie Conlon

Conference papers

A first year module which introduces students to the social dimension of engineering is described. The key teaching tool is the use of group projects to develop students’ learning skills. The importance of addressing the motivation for engineering students studying non-technical modules is emphasised. Data used to evaluate the module is presented. It is shown that the nature of the project undertaken affects the attainment of learning outcomes. The conclusion focuses on some shortcomings of the module and highlights the importance of appropriately structuring the learning environment to facilitate self-directed learning by early year students.

Machine Annotation Of Sets Of Traditional Irish Dance Tunes, Bryan Duggan, Mikel Gainza, Padraig Cunningham

Conference papers

A set in traditional Irish music is a sequence of two or more dance tunes in the same time signature, where each tune is repeated an arbitrary number of times. A turn in a set represents the point at which either a tune repeats or a new tune is introduced. Tunes in sets are played in a segue (without a pause) and so detecting the turn is a significant challenge. This paper presents the MATS alogrithm, a novel algorithm for identifying turns in sets of traditional Irish music. MATS works on digitised audio files of monophonic flute and tin-whistle music. …

Single Channel Sound Source Separation Combining Delay Estimation And The Adress Algorithm, Mark Leddy, Dan Barry, David Dorran, Eugene Coyle

Conference papers

A method for single channel source separation is proposed in this paper, which uses estimates fo the delay co-efficient of individual sources within an echoic mixture using autocorrelation, following which a "pseudo-stereo mixture" is generated, to which the ADRess algorithm can be applied. The system is evaluated in a theoretical situation, where the mixture signal to be separated consists of two individual source signals, and a delayed version of each signal. Estimates of the individual delay lengths are made and then used to create a pseudo stereo mix, where one channel consists of the orginal mixture signal, and the second …

Key Signature Estimation, Matt Cranitch, Derry Fitzgerald, Matthew Hart

Conference papers

The problem of automatic key signature detection has been the focus of much research in recent years. Previous methods of key estimation have focused on chromagrams and key profiling techniques. This paper presents a remarkably simple but effective method of estimating key signature from musical recordings. The algorithm introduces the "keyogram", a concept resembling the chromagram, and is aimed for use on traditional Irish music. The keyogram is a measure of the likelihood of each possible major key signature based on a masked scoring system.

Automating Ornamentation Transcription, Mikel Gainza, Eugene Coyle

Conference papers

A novel technique for detecting single and multi-note ornaments is presented. The system detects audio segments by utilising and onset detector based on comb filters (ODCF), which is capable of detecting very close events. In addition, a novel method to remove spurious onsets due to offset events is introduced. The system utilises musical ornamentation theory to decide whether a sequence of audio segments correspond to an ornamentation musical structure. In order to evaluate the results, a database of signals produced by different players using the three different instruments has been utilised. The results represent a step forward towards fully automating …

Recruitment And Retention: The Role Of The Public Image Of Engineering, Eddie Conlon

Conference papers

This paper presents findings of three surveys conducted with first year students in the Faculty of Engineering in the Dublin Institute of Technology. It focuses on their motivation for studying engineering and the people who influenced the decision to do engineering. It shows there are gaps in the students’ knowledge of their programmes and also between their expectations and their experience of their course. Some proposed areas of action are identified to increase both recruitment and retention. It is argued that projecting an image of engineering as a creative activity would help in addressing recruitment and retention issues.

Educating Engineers For The 21st. Century: And Why Some Elements Of History And Philosophy Should Be Incorporated Into The Curriculum, William Grimson, Mike Murphy, Eugene Coyle

Conference papers

It has been said that in some respects the Russian composer Igor Stravinsky was a magpie – borrowing styles and ideas from diverse sources for whatever musical project he was working on. The practice of engineering has this same characteristic in that it willingly takes ideas, knowledge and techniques from wherever in pursuit of completing its goal. Further, Engineering is, at least in part, in agreement with Fyodor Dostoevsky – ‘if everything on Earth were rational, nothing would happen’. Against such a background it is proposed that a framework based on both philosophy and the history of engineering, science and …

Growing Research In A Traditionally Teaching-Oriented College, Mike Murphy, Michael Dyrenfurth

Conference papers

There is increasing pressure on universities to contribute to ‘the knowledge society’ by increasing the level of research activity and output within the university. This is particularly true in the sciences, engineering and technology. This increased pressure applies equally to traditionally teaching-oriented colleges (TTOC), although not at the same scale as research-intensive universities. For the TTOC, given the primacy of teaching, this paper discusses the nexus between teaching and research and the question ‘why do research?’ is addressed within the overarching goal of embedding a research culture within the college. Initiatives to develop and grow sustainable research activity in traditionally …

Resynthesis Methods For Sound Source Separation Using Shifted Non-Negative Factorisation Models, Derry Fitzgerald, Matt Cranitch

Conference papers

Recently, techniques such as shifted 2D non-negative matrix factorisation and shifted 2D non-negative tensor factorisations have been proposed as methods for separating harmonic musical instruments from single and multi-channel mixtures. However, these methods require the use of a Constant Q transform, for which no true inverse exists. This has adverse effects on the quality of the resynthesis of the separated sources. In this paper, a number of different resynthesis methods are investigated in order to determine the best approach to resynthesis

Towards A Personal Automatic Music Playlist Generation Alogorithm: The Need For Contextual Information, Gordon Reynolds, Dan Barry, Ted Burke, Eugene Coyle

Conference papers

Large music collections afford the listener flexibility in the form of choice, which enables the listener to choose the appropriate piece of music to enhance or complement their listening scenario on-demand. However, bundled with such a large music collection is the daunting task of manually searching through each entry in the collection to find the appropriate song required by the listener. This often leaves the listener frustrated when trying to select songs from a large music collection. In this paper, an overview of existing methods for automatically generating a playlist is discussed. This discussion outlines advantages and disadvantages associated with …

Time Signature Detection By Using A Multi Resolution Audio Similarity Matrix, Mikel Gainza, Eugene Coyle

Conference papers

A method that estimates the time signature of a piece of music is presented. The approach exploits the repetitative structure of most music, where the same musical bar is repeated in different parts of a piece. The method utilised a multi-resolution audio similarity matrix approach, which allows comparisons between longer audio segments (bars) by combining comparisons of shorter segments (fraction of a note). The time signature method only depends on musical structure, and does not depend on the presence of percussive instruments or strong musical accents.

Technology Influences On Small Logistics Providers: A Case Study Analysis, Pietro Evangelista, Alan Mckinnon, Edward Sweeney

Conference papers

ICT has triggered many changes in the logistics service industry. New technology is reshaping the organisation and structure of this industry as ICT impacts significantly on the operations of 3PLs. Within this process, while large 3PLs are gaining substantial benefits from technology usage, the nature of changes resulting from ICT usage in small 3PLs remains unclear. This is critical particularly for those markets populated by a high number of small 3PLs such as the Italian logistics industry. From the research point of view, there is still a gap in the literature where the role of technological capability in small 3PLs …

Outsourcing In Ireland: A Literature Review And Survey Perspective To Construct An Outsourcing Roadmap, Aoife O'Riordan, Edward Sweeney

Conference papers

This paper investigates what is happening in Ireland at the moment regards outsourcing. It looks into the literature review and the survey conducted. The research took place over a period of two years, initially as a literature review, and then the survey was conducted through the mediums of e-mail and the postal service. The survey analysis found that Ireland was the most likely place for Irish companies to outsource to, and that nearly 40 percent of the companies that have been surveyed have started on their latest outsourcing initiative since 2004. This indicates that outsourcing is still important on the …
