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% …

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. …

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.

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.

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 …

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 …

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.
