The net impact analyses were conducted using a nonexperimental methodology. Individuals who had encountered the workforce development programs were statistically matched to individuals who had not. Administrative data with information from the …

Localised Galvanic Corrosion Processes In Thermal Spray Coated/Cast Aluminium Alloy Systems, David Culliton, Tony Betts, David Kennedy

Conference Papers

Cast Aluminium Alloys, because of the propensity of aluminium to react with impurities and alloying elements, are prone to developing IM impurities during the solidification process. These IM phases can act, in some fluids, as initiation sites for localised corrosion processes, resulting in degradation phenomena, such as pitting. Whilst Thermal Spray coatings can improve the wear resistance of Cast Aluminium Alloys, their corrosion performance may be hampered by the presence of through porosity within the coating.

The present work details some preliminary studies of the localised corrosion processes occurring at the interface area between a Thermal Spray coating and a …

Analysis Of Assessment And Learning Strategies For A Logistics Undergraduate Education Programme, Margaret Farrell

Conference Papers

It is recognised that in today’s global competitive marketplace, where outsourcing continues to grow at an exponential rate, Logistics and Supply Chain Management (SCM) have grown in importance [1]. Research suggests that as logistics moves from being viewed as a stand alone discipline to one viewed as integrating the management of supply, the duties, managerial skills and knowledge of the Professional Logistician have changed [2] [3] . The challenge for logistics educators is to design and develop curricula, learning, teaching and assessment strategies that can support wide-ranging and integrative learning objectives. Research also states that universal logistics management skills must …

Media Literacy And The Public Sphere: Contexts For Public Media Literacy Promotion In Ireland, Brian O'Neill

Conference Papers

The concept of media literacy has undergone significant transformation in recent years from its origins in media education discourse to the current pivotal role it occupies in emerging European media policy formations. Its insertion within the Audiovisual Services Directive is an indicator of the significance attached to it at European Commission level. Media literacy, in addition to denoting critical media awareness, is increasingly viewed as essential to maintaining inclusivity in a rapidly changing environment for converged information and communication services. But what, in this context, does media literacy now mean and does it fit appropriately within the ‘moral agenda’ (Silverstone …

Preparation & Accreditation Of Level 7 Engineering Programmes, Mark Mcgrath

Conference Papers

Accreditation of 3rd level educational programmes by a suitably recognised professional body is of particular relevance in relation to engineering. The completion of a sequence of modules which leads to the attainment of this professionally recognised award is viewed as integral to the undertaking. The engineering technology fields are developing and expanding rapidly and the third level sector must keep abreast of these changes. This is essential if the third level institutions wish to continue delivering programmes which produce graduates who can successfully complete the transition from 3rd level to the various engineering sectors. This paper outlines various aspects of …

An Engineering Evaluation Of Ankle Prosthetics, Christopher Thian, Stephen Tiernan, Fiona Mcevoy, Robert Flavin

Conference Papers

There are a wide range of different types of ankle replacements on the market today each with a
different mechanical design. Unfortunately the results of ankle replacements are not as good as hip
and knee replacements; this is due to the complexity of the ankle joint. In the early days of ankle
replacements some of the prosthetics only lasted 4 months. Recent developments have improved the
longevity of the replacements although, there are still many complications and failures of the
replacements, these include; the prosthetic components migrating into the bone, the components
failing due to stresses induced by the forces …

Big Challenges In Designing Small Parts For Mass Production, Kevin Delaney, David Kennedy

Conference Papers

Micro manufacturing involves the production of parts or products with features on a micro scale. The technology is used to produce parts for several business sectors which have experienced dramatic growth in recent years and forecasts are that this growth will continue in the years ahead. With the loss of traditional manufacturing jobs to lower-cost locations many companies in Ireland see micro manufacturing as having significant potential to preserve and increase revenue. A move into micro manufacturing will present significant opportunities for those companies willing to take the risk of producing parts with micro dimensions. Such a transition is a …

Real-World Process Design For Mechanical Engineering Students: A Case Study Of Pbl In Dit, Kevin Delaney, John D. Kelleher

Conference Papers

Engineering education deals primarily with calculating quantitative performance of engineering objects, such as machines, circuits or dams, and with designing variations of these objects. However when engineering graduates enter the workforce they must be able to do a great deal more than solve the technical problems taught in engineering school [1]. More specifically they will need to deal with a great range of problems some of which are not technical engineering problems at all. Examples of such problems include working as part of a larger group, project management, negotiation, component sourcing and an awareness of the multi-disciplinary nature of engineering. …

Assessment Of The Effects Of Increasing Levels Of Physiological Realism In The Computational Fluid Dynamics Analyses Of Implanted Coronary Stents, Jonathan Murphy, Fergal Boyle

Conference Papers

Coronary stent implantation can improve blood flow in an artery that has been narrowed by the build up of arterial plaque. However, the implantation of the stent will change the geometry of the vessel wall. The haemodynamic effects of the stents presence and alteration of the vessel wall are unclear. The redistribution of flow induced vessel wall shear stress (WSS) and wall shear stress gradient (WSSG) may directly contribute to restenosis (re-blockage). Computational fluid dynamics (CFD) is used extensively to identify these parameters in stented vessels. However, simplifications to the model of the stented artery are common. In this paper, …

The Application Of Web 2.0 Technologies As An Experimental Method Of Teaching Remote Sensing At Dit, Ireland, Avril Behan

Conference Papers

This paper describes the implementation of an experimental method of delivery for a module of remote sensing material to second year students on the BSc (Hons) in Geomatics at the Dublin Institute of Technology. The project began as a reaction to poor levels of student engagement and unsatisfactory grades, as well as the requirement to focus more on real-world type problems due to the implementation of a work-placement semester for third year students. Both pedagogical considerations (movement towards formative feedback, interactivity and group-based work) and the effect of technological drivers, such as the popularity of the internet in general and …

An Exploration Of A Discrete Rhombohedral Lattice Of Possible Engineering Or Physical Relevance (Revised Version) 2008, Jim Mcgovern

Conference Papers

A particular discrete rhombohedral lattice consisting of four symmetrically interlaced cuboctahedral point lattices is described that is interesting because of the high degree of symmetry it exhibits. The four constituent cuboctahedral lattices are denoted by four colours and the composite lattice is referred to as a 4-colour rhombohedral lattice. Each point of the 4-colour lattice can be referenced by an integer 4-tuple containing only the positive non-zero integers (the counting numbers). The relationship between the discrete rhombohedral lattice and a discrete Cartesian lattice is explained. Some interesting aspects of the lattice and of the counting-number 4-tuple coordinate system are pointed …

Metrology And Proportion In The Ecclesiastical Architecture Of Medieval Ireland, Avril Behan, Rachel Moss

Conference Papers

The aim of this paper is to examine the extent to which detailed empirical analysis of the metrology and proportional systems used in the design of Irish ecclesiastical architecture can be analysed to provide historical information not otherwise available. Focussing on a relatively limited sample of window tracery designs as a case study, it will first set out to establish what, if any, systems were in use, and then what light these might shed on the background, training and work practices of the masons, and, by association, the patrons responsible for employing them.

Surface engineering refers to a wide range of technologies that design and modify the surface properties and characteristics of components. The applications are very broad from macro to nano and from extremely hard materials to polymeric coatings. The uses are found in many engineering, energy, gas and oil, transport, medical, cosmetic, optical, chemical and sports industries. Research in this technology is ongoing and the benefits that can be derived are enormous. The design, wear and tribological properties of components for instance have been greatly enhanced by surface engineering and the economic benefits to industries far outweigh the cost and use …

Dab Eureka-147: The European Vision For Digital Radio, Brian O'Neill

Conference Papers

The digitalisation of radio broadcasting has a long history and as a project has been under active consideration for at least 25 years. A number of different technical approaches to digital radio exist, the longest established of which is the so-called Eureka-147 or DAB (Digital Audio Broadcasting) system. This paper explores the ‘technological imaginary’ of DAB and its distinctly ‘European’ vision for new media and the future of broadcasting. It examines its origins in European R&D policy of the 1980s, and its affinity with European broadcasting practice, particularly within a public service tradition. Ironically, it was DAB’s failure to capitalise …

An Analysis Of The Performance Of Foams Used In Hurling Helmets, Keith Norris, Stephen Tiernan

Conference Papers

Abstract Head injuries can occur in most sporting activities. The seriousness of these injuries can vary greatly depending on the sport. Many sports such as American football, cricket, baseball and hurling try to reduce this risk by designing helmets that are suitable to be worn by the players. The National Standard Authority of Ireland (NSAI) has recently made great strides in this area with the introduction of the first comprehensive standard adopted for the sport I.S. 355:2006, which sets out new testing procedures that all new helmets must meet. The Gaelic Athletic Association (GAA) has also stated its intention to …

Conference Papers

The role of cyclodextrin’s (CD) in drug delivery has advanced in recent years and this may be attributed to its biocompatibility and well established synthesis. Chemical modification of CDs has shown to extend the physicochemical properties and the host capacity for a variety of drugs. β-CD has been widely used in the early stages of pharmaceutical applications because of its ready availability and its cavity size suitability for a wide range of drugs. Chemical modification of β-CD has proven to enhance aqueous solubilisation, microbiological stability and reduced toxicity in previous studies.1 Folate Receptors are over-expressed in several human cancers including …

Force Measurement And Evaluation For Surgical Cutting Applications: Development Of An Effective Characterisation Testbed, Dean Callaghan

Conference Papers

Sensorized instruments that cater for accurate measurement of the interaction forces (between biological tissue and instrument end-effector) during surgical procedures offer surgeons a greater sense of immersion during minimally invasive robotic surgery (MIRS). There is much ongoing research into force measurement/evaluation involving surgical graspers. However, comparatively little corresponding effort has been expended in the measurement and subsequent evaluation of forces between scissor blades and tissue. This paper presents the design and development of a force/strain measurement test apparatus, which will ultimately serve as an effective sensor characterisation and evaluation platform. Data acquired from the testing platform can be used to …

Analysis Of A Pilot Implementation Of Problem Based Learning Strategy For A Logistics Undergraduate Education Programme, Margaret Farrell

Conference Papers

Research findings suggest that a supply chain manager's job is complex and multidimensional, requiring both general management and logistics/supply chain specific knowledge, competencies and skills. The challenge for logistics educators is to design and develop curricula, teaching and assessment methodologies that can support wide-ranging and integrative learning objectives, which include team, people, project management and technological skills. Problem based learning (PBL) draws heavily on andragogical principles, requiring the student to be self directed and responsible for their own learning as they seek to solve a ‘real life’ problem, within a group. The paper presents the analysis of the teachers experience …

Back To The Future: The Emergence Of Contrasting European And Us Approaches To Digital Radio, Brian O'Neill

Conference Papers

Digital radio has been in development for over 25 years and yet is no nearer a point of successful adoption. This paper explores the emergence of contrasting European and American approaches to digital radio. The most established of these, Eureka-147 or Digital Audio Broadcasting (DAB), which originated in Europe, is contrasted with the so-called IBOC or /HD Radio approach, as alternative collective conceptualizations of how technology can bridge contemporary broadcasting practice to an ̳imagined‘ digital future. Drawing on the concept of ̳symptomatic technology‘ (Williams 1974), DAB‘s origins in European R&D policy of the 1980s and its affinity with established European …

Development Of A Three Dimensional Prolapse Model To Simulate Physiological Haemodynamics In A Stented Coronary Artery, Jonathan Murphy, Fergal Boyle

Conference Papers

Coronary stent implantation can improve blood flow in an artery that has been narrowed by the build up of arterial plaque. However, the haemodynamic effect of stent placement is unclear and may influence arterial restenosis (re-blockage). The degree of tissue prolapse between stent struts may be an important factor in predicting the restenosis rate of a stent due to the haemodynamic influence of the protruding tissue. In this paper a mathematical model has been developed to numerically predict the tissue prolapse for an artery implanted with a coronary stent. The prolapse model has been applied to the Gianturco-Roubin II (GR-II) …
