Professional Skills Portfolio For A Progressive Engineering Education, Dermot Mcgarthy, David Kennedy
Professional Skills Portfolio For A Progressive Engineering Education, Dermot Mcgarthy, David Kennedy
Articles
At the 2013 launch of the return to work scheme, “Springboard” in Dublin, it was stated that employers were seeking staff with enhanced language, presentation, communication, coping, and team-working skills. Graduates without these skills were finding it more difficult to gain permanent employment and were more likely to find themselves out of work unless they developed these skills. Enhancing personal development skills in education requires a revision of existing programmes. Not alone will these skills open new doors of opportunity for those who have lost their jobs during the recession, but should help sustain them going forward. The education of …

Managing Moisture - The Key To Healthy Internal Wall Insulation Retrofits Of Solid Walls, Joseph Little, Benat Arregi
Managing Moisture - The Key To Healthy Internal Wall Insulation Retrofits Of Solid Walls, Joseph Little, Benat Arregi
Conference papers
This study investigates the appropriateness of internally insulating solid walls to the Passivhaus standard. A number of variables are assessed using numerical hygrothermal simulation (under EN 15026) to check (1) associated risk of mould growth on original substrate and (2) if they result in a greater likelihood of timber decay at built-in joist ends. While air and vapour control layers (AVCLs) perform well regarding mould risk in low absorption walls, the results question their appropriateness where joist ends are built-in: when AVCLs are used, moisture levels at joist ends can potentially rise above critical thresholds, even in low absorption walls. …
Comparative Study Of Artificial Lighting Systems With Different Fixtures Considering Daylight Availability, Leticia Niero Moraes, Anderson Claro
Comparative Study Of Artificial Lighting Systems With Different Fixtures Considering Daylight Availability, Leticia Niero Moraes, Anderson Claro
CIBSE & SLL International Lighting Conference, Dublin, 2013
The use of daylight is indicated as a primary factor in energy savings of buildings, since it can reduce the use of electric lighting through control systems. However, the efficiency of systems is also associated with technical characteristics and performance of various elements. The positioning of fixtures, as well as its specifications can contribute for environmental comfort and energy conservation. Such concerns, however, are not part of the currently established practice of lighting design professionals. Considering this gap, this paper seeks to develop a study that addresses the integration of natural and electric light. The methodology is based on evaluating …

Building Information Modelling (BIM) can provide a focus on collaboration between the designers, constructors and facility management (FM) personnel leading to major efficiencies in the operational and maintenance phase of a building. The information within a model can be extracted at various stages throughout the project life cycle using the Construction-Operation Building Information Exchange (COBie) schema that provides an open framework for the exchange and delivery of construction handover information. However, it is then up to the FM software companies to take the information and display it in a user friendly way. The authors have set about enhancing an established …
Estimating The Wind Resource In An Urban Area: A Case Study Of Micro Wind Generation Potential In Dublin, Ireland, Keith Sunderland, Gerald Mills, Michael Conlon
Estimating The Wind Resource In An Urban Area: A Case Study Of Micro Wind Generation Potential In Dublin, Ireland, Keith Sunderland, Gerald Mills, Michael Conlon
Articles
The micro-turbine wind market in cities faces significant challenges due to the complexities associated with the urban terrain but, if a renewable solution to increasing energy demand is to be achieved, energy conversion systems where populations are concentrated, that is cities, must be considered. This research evaluates the urban wind resource by employing a physically-based empirical model to link wind observations at a conventional meteorological site to those acquired at urban sites. The approach is based on urban climate research that has examined the effects of varying surface roughness on the wind-field between and above buildings. Here, this is applied …
Supply Chain "Mega-Trends": Current Status And Future Trends, Edward Sweeney
Supply Chain "Mega-Trends": Current Status And Future Trends, Edward Sweeney
Practitioner Journals
The supply chain management (SCM) concept has become embedded in the thinking of many organisations in recent years. Originally introduced by management consultants in the early 1980s, SCM has a strong focus on integration of processes across functions within firms, as well as between the organisations that comprise the wider extended enterprise. There is a significant body of research to support the notion that the consistent delivery of value to customers is predicated on higher levels of intra-firm and inter-firm integration. Putting the supply chain integration (SCI) concept into practice is critically dependent on the ability of firms to manage …

Detecting Point-Like Sources Of Unknown Frequency Spectra, Raffaele Solimene, Giuseppe Ruvio, Angela Dell’Aversano, Antonio Cuccaro, Max Ammann, Rocco Pierri
Articles
The problem of detecting point-like sources whose frequency spectrum is unknown is addressed. Limitations of single-frequency approaches are identified by analytical as well as numerical arguments. To overcome these limits, different multifrequency approaches which combine frequency data incoherently are compared. In particular, a novel multifrequency MUSIC-like algorithm based on interferometric concepts is proposed. Results show that the algorithm outperforms other methods under comparison.

Competition between Irish contractors is more aggressive than ever before. In the current economic climate an ability to construct with greater efficiency could ensure a company’s survival. The purpose of this research was to determine the extent to which efficiency benefits could be realised by contractors on design and build projects as a result of implementing a revolutionary process referred to as Building Information Modelling (BIM). After a critical analysis on all aspects of BIM in the literature review, questionnaires were sent to establish the success of this system in the US and also in the comparatively few Irish firms …

As part of our teaching in the Departments of Fabrication and Transport Engineering in the Technological University Dublin we use industrial metal folding machines to help students to learn the sequencing of folds on manufactured sheet metal components. Many students have difficulty visualising the folding sequences required to complete practical manufacturing assignments. This paper details the digital media resource which was developed to provide students with the opportunity to offer a proposed solution to questions which relate to the folding sequence required for these components. Feedback is provided through the medium of pre recorded videos which show the component being …
Feedback Dynamics In The Academic And Industrial Environment, David Kennedy, Dermot Mcgarthy
Feedback Dynamics In The Academic And Industrial Environment, David Kennedy, Dermot Mcgarthy
Conference Papers
Feedback is essential in all companies, in society and in educational environments. We learn, improve and develop from it in our examinations, group work, work environment and relationships. Feedback however must be supported with good communications and be consistent. In the classroom environment this means providing feedback in a positive and supportive manner, and being consistent to all. Most if not all managers and leaders, including lecturers have not undertaken any form of training in feedback methods and therefore it is not translated effectively, causing stress or misguidance to students and colleagues. This paper highlights the importance of good feedback, …
The Effects Of Physical Activity On Greenhouse Gas Emissions For Common Transport Modes In European Countries, Aidan Duffy, Robert Crawford
The Effects Of Physical Activity On Greenhouse Gas Emissions For Common Transport Modes In European Countries, Aidan Duffy, Robert Crawford
Articles
This paper applies a life cycle methodology to estimate activity-related contributions of transport modes to GHG emissions. The methodology uses national input-output tables, environmental accounts, household budget data and nutritional data to derive food-sector GHG coefficients of consumption for ten European countries. The food energy requirements for each mode of transport are estimated taking account of the modal activity level and energy requirements. Walking, cycling, driving and bus travel are considered. Typical national food energy-related emissions for walking, cycling, and driving ranged from 25.6 - 77.3 gCO2-eq/pass.km, 10.4 - 31.4 gCO2-eq/pass.km and 1.7 - 5.2 gCO2-eq/pass.km; passenger transport was found …

Development Of Novel Fiber Optic Humidity Sensors And Their Derived Applications, Jinesh Mathew
Doctoral
The main focus of this thesis is on the design and development of novel fiber optic devices for relative humidity (RH) sensing with emphasis on high sensitivity, a wide humidity range, low temperature dependence, fast response time and good stability.
Novel RH sensors based on fiber bends are fabricated by coating the surface of the buffer stripped bent fiber with selected hygroscopic materials such as Polyethylene oxide or Agarose. It is shown that the Polyethylene oxide coated device has a high sensitivity in a narrow RH range while the Agarose coated fiber bend shows a linear RH sensitivity in a …
