Two Number-Theoretic Problems That Illustrate The Power And Limitations Of Randomness, Andrew Shallue

Scholarship

This thesis contains work on two problems in algorithmic number theory. The first problem is to give an algorithm that constructs a rational point on an elliptic curve over a finite field. A fast and easy randomized algorithm has existed for some time. We prove that in the case where the finite field has characteristic 2, there is a deterministic algorithm with the same asymptotic running time as the existing randomized algorithm.

Experiences With Virtual Learning Environments In Control Engineering Education, Aidan O'Dwyer

Conference papers

The twin pressures of the need for students to learn a wider variety of concepts, ideally in a self-learning mode, and the reduction in class contact time has led to the use of increased levels of information technology in control engineering education. This paper reports on, reflects on, and evaluates the author’s use of virtual laboratories (computer based laboratories available on the internet) in control engineering modules at DIT Kevin St. The use of the virtual laboratories helps in the ongoing evolution of the teaching approach from a traditional didactic lecture and laboratory course to a more learner-centred approach. The …

Using Controller Tuning Formulae To Improve Performance, Aidan O'Dwyer

Conference papers

The proportional integral derivative (PID) controller is the most dominant form of automatic controller in industrial use today. With this device, it is necessary to adjust the controller parameters according to the nature of the process. Thus, for effective control of a HVDC system, for example, specific values need to be chosen for the P, I and D parameters, which will be different for the values required to control, for example, an induction motor drive. This tailoring of controller to process is known as controller tuning. Controller tuning is easily and effectively performed using tuning rules (i.e. formulae for controller …

Academic Change In Higher Education In Europe, Kevin Kelly, Mike Murphy

Conference papers

This paper analyses academic change in higher education internationally but mainly in Europe. It examines one College in Ireland as it faces major change and examines whether best practice change that has been successful elsewhere might be appropriate in this particular setting, with it’s own culture and history. Research is ongoing, using qualitative inquiry and fourth generation evaluation which seeks to address the concerns and issues of stakeholders. It is an illuminative evaluation project that seeks to allow senior management in the College see what is happening elsewhere and evaluate whether such methods might be appropriate in their own college. …

Diffusion And Fractional Diffusion Based Models For Multiple Light Scattering And Image Analysis, Jonathan Blackledge

Articles

This paper considers a fractional light diffusion model as an approach to characterizing the case when intermediate scattering processes are present, i.e. the scattering regime is neither strong nor weak. In order to introduce the basis for this approach, we revisit the elements of formal scattering theory and the classical diffusion problem in terms of solutions to the inhomogeneous wave and diffusion equations respectively. We then address the significance of these equations in terms of a random walk model for multiple scattering. This leads to the proposition of a fractional diffusion equation for modelling intermediate strength scattering that is based …

Engineering Science As Opposed To Natural And Applied Science, Eugene Coyle, Mike Murphy, William Grimson

Books/Book chapters

In exploring the epistemology of engineering science we propose a model of engineering. This model incorporates the goals of engineering, the approach to engineering (also called the engineering method) and the role of experience in engi-neering. The basis for understanding the nature of engineering science will be ex-plored, and will be contrasted with natural science. To begin, a large-scale engi-neering project that was successfully completed in Ireland many years ago is dis-cussed - specifically, the development of a megalithic passage tomb as an exemplar of the engineering method in structural design, project management and aesthetics. This exemplar firmly demonstrates that …

Final Report: Critical Media Literacy In Ireland, Cliona Barnes, Farrek Corcoran, Flanagan Brian, Brian O'Neill

Reports

Critical Media Literacy (CML) is a matter of major public importance. The skill-set of CML is increasingly recognised at national and European level as essential to citizenship and to a healthy democracy. Attempts to foster Media Literacy have been a feature of Irish education for over thirty years. Extensive curriculum reform has taken place to ensure that opportunities for studying the media are available across the primary and secondary curriculum.

However, in 2007 the subject retains a low profile and provision for Media Education is uneven. The subject has a low status within the educational system and media exploration is …

Making Olsr Aware Of Resources, Karol Kowalik, Brian Keegan, Mark Davis

Conference papers

An important element of any routing protocol used for Wireless Mesh Networks (WMNs) is the link cost function used to represent the radio link characteristic. The majority of the routing protocols for WMNs attempt to accurately characterise the radio link quality by constructing the link cost function from the measurements obtained using active probing techniques which introduces overhead. In this paper we present a modified version of the Optimized Link State Routing (OLSR) protocol which uses the link cost function values provided the Resource Aware Routing for mEsh (RARE) module which employs passive monitoring to gather radio link information. This …

Risk Reduction Through Technological Control Of Personal Information, Shirley Atkinson

School of Engineering, Computing and Mathematics Theses

Abuse and harm to individuals, through harassment and bullying, coexist with Identity Theft as criminal behaviours supported by the ready availability of personal information. Incorporating privacy protection measures into software design requires a thorough understanding about how an individual's privacy is affected by Internet technologies. This research set out to incorporate such an understanding by examining privacy risks for two groups of individuals, for whom privacy was an important issue, domestic abuse survivors and teenagers. The purpose was to examine the reality of the privacy risks for these two groups. This research combined a number of approaches underpinned by a …

Towards A Conceptual Framework Of Corporate Branding In Retailing, Edmund O'Callaghan

Conference proceedings

The view that corporate brand building in retailing is different to any other context (Burt and Sparks, 2002) is predicated in the belief that ‘goods’ retailers need to manage a range of corporate components, its multiple relationships with customers and its dependence on employees to personify and deliver much of the corporate identity. These differences in operations are perceived as adding a degree of complexity to an already challenging process of corporate brand development. This paper proposes a conceptual framework for the corporate brand building process within an SME retail context. It develops on the work of Hatch & Schultz’s …

Does Understanding National Business Cultures Help Build Regional Development?, Amanda Ratcliffe, Thomas Cooney Dr.

Conference proceedings

An EFER report in 1995 observed that little of the growth ofEurope’s top 500 companies came from existing products in existing markets, but almost two-thirds of the growth came from entering new markets. A large majority of Europe’s 500 are active in export markets, with exports accounting for 40% of their turnover as opposed to the 10% export share for SMEs overall. One of the critical reasons for the poor performance of SMEs within the international arena is their ignorance of local business cultures. Yet for a country – or a specific region – to achieve strong economic growth, it …

Optimized Fatigue And Fracture Performance Of Friction Stir Welded Aluminium Plate: A Study Of The Inter-Relationship Between Process Parameters, Tmaz, Microstructure, Defect Population And Performance, Hannalie Lombard

School of Engineering, Computing and Mathematics Theses

Friction stir welding (FSW) is an exciting new solid-state welding process with the potential to advantageously impact many fabrication industries. Current take-up of the process by industry is hindered by lack of knowledge of suitable welding parameters for any particular alloy and sheet thickness. The FSW process parameters are usually chosen empirically and their success is evaluated via simple mechanical property testing. There are severe drawbacks with such methods of determining manufacturing conditions. These include indirect relationships between tensile and fatigue properties, particularly for welds, and a high probability of totally missing real optimized conditions. This research is therefore undertaken …

Guardian Angel (Ireland), Thomas Cooney

Case studies

It was the summer of 2006 and three friends of many years had come up with a business idea that they believed could be a money-spinner for all of them. Maria Harrison, Krystle Malone and Marie Lyons had all been students at the Technological University Dublin and had recently completed their degree in Marketing. As part of their programme, they had taken a course on Entrepreneurship by way of interest rather than any deep-rooted desire to start their own business. But now, they are about to meet a venture capital company to ask for €300,000 to get the business started. …

Echinades Fish Farm (Greece), Thomas Cooney

Case studies

The past decade had seen a dramatic decline in the regional economy along the west coast of the Greece as agriculture faded and few incentives existed for manufacturing companies to locate there given its relatively poor infrastructure. Since the long-established Greek strength of tourism was still focused on the islands and in areas where large natural beaches offered holidaymakers the opportunity to lay out in the glorious Mediterranean sunshine, this region of barren land and traditional lifestyle offered little to entice the modern tourist. Despite this pessimistic background, Nikos Anagnopoulos stood on the deck of the small boat that had …

It was yet further recognition that …

Enhancing Educational Programmes For Geomatics In Ireland, Frank Prendergast, William Prendergast, Avril Behan, Helen Murray

Conference Papers

The growing spatial information needs of society, the rapid development of new surveying technologies, and the global demand for appropriately qualified surveyors, have triggered a radical re-evaluation of Geomatics education in Europe. Although significant enhancements to DIT’s educational programmes have been made during the last decade, the provision of new opportunities for learners and innovative changes to existing paradigms of training and education are required. This paper addresses some of the issues confronting educators in DIT, and presents some of the strategies for their enhancement and implementation.
