Tunepal: the Traditional Musician's Toolbox
(2010)
Duggan, Bryan
Abstract:
<p>In this paper we present Tunepal, a search engine and music retrieval tool for traditional musicians that runs on an iPhone/iPod Touch (2nd generation)/iPad. Tunepal connects musicians the scores and metadata of 13,290 traditional Irish, Welsh, Scottish and Breton dance tunes. These tunes are drawn from community sources, such as the website thesession.org and “standard” references including O’Neills Dance Music of Ireland and Brendan Breathneach’s Ceol Rince Na hÉireann series. Tunes can be retrieved by typing in a title or by playing a twelve second extract from the tune on a traditional instrument. Tunepal can be used in sitiu in traditional music sessions, classes and concerts. This paper presents background information on the sources of music contained in the Tunepal corpus and describes the functionality, operation, development and usage of the app.</p>

An Investigation into Feature Selection for Oncological Survival Prediction
(2012)
Strunkin, Dmitry; Mac Namee, Brian; Kelleher, John
Abstract:
<p>In machine learning based clinical decision support (CDS) systems the features used to train prediction models are of paramount importance. Strong features will lead to accurate models, whereas as weak features will have the opposite effect. Feature sets can either be designed by domain experts, or automatically extracted for unstructured data that happens to be available from some process other than a CDS system. This paper compares the usefulness of structured expert-designed features to features extracted from unstructured data sources in an oncological survival prediction application scenario.</p>

Cloud Computing Adoption for SMEs: Challenges, Barriers and Outcomes
(2012)
Akbari, Mojtaba
Abstract:
<p>In spite of all the excitement and fuss around cloud computing technologies in recent years, it is believed that the industry has been to some extent lagging behind when it comes to the deployment of cloud technologies and migration from legacy Information Technology (IT) infrastructure. This research aims to investigate the influential factors that impact adoption of cloud-based technologies by various organizations. More specifically, this research focuses on the behaviour of Small and Medium Enterprises (SMEs) rather than larger organizations. Such classification is crucial since the constraints applicable to SMEs are different to their larger counterparts and subsequently the decision mechanisms and influential factors are dissimilar. The research is conducted through design and implementation of a real cloud-based solution that has been evaluated by three SMEs from different sectors and with different requirements. Subsequently, using the cloud-based test-bed, a number...

The Effect of Learning Styles and E-Learning Tools on the Training of ICT to Digital Immigrants in Life Long Learning
(2012)
Horan, Stephen
Abstract:
<p>The diversity of learners in the classroom has expanded significantly in the past twenty years, in a modern classroom it is unsurprising to see learners for whom English is not their first language, learners with specific learning difficulties, mature learners, learners attempting to return to work, etc., so much so that the 'typical' learner has become extinct. This research will look at the use of Information Communication Technology in Education by undertaking an investigation of how the use of ICT can aid learners, both digital natives and digital immigrants. The project will use learning styles at the core of an e-Learning tool developed as a model of diversity. A great deal of research has been carried out in this area with regard to learning styles and how interaction with ICT can facilitate learning. In this work a range of students will be introduced to an e-Learning tool to aid in their learning of a specific topic, in this case a small element of spread...

An Investigation into Obstacles Effecting the Use of Support Technology for Accommodation Facilitation in Third Level Education
(2012)
Brennan, Conor
Abstract:
<p>The profile of students attending third level education in Ireland has changed over the past number of years. More non-traditional students have entered mainstream education. These non-traditional students may be mature students, students whose first language is not English and students with disabilities. In the 2010-2011 academic session 6,932 students with disabilities were enrolled in third level education. This represent 3.9%(AHEAD 2011) of all students enrolled in third level education, which constitutes a 10% increase on 2009-2010. This increase is putting pressure on an already strained system. Efforts have been made to educate and inform lecturers and teaching staff on their role and responsibility in the student journey. The responsibility of students with disabilities lies with each third level institutes disability or access service. This research investigated the role of eLearning resources in providing support for disability services in third level education. T...

Investigation and Analysis of Open Government Data in Ireland, and the Creation of a Set of Quality Guidelines to Aid its Utility Within Mobile Application Development
(2012)
Fitzpatrick, Peadar
Abstract:
<p>Governments are the custodians of vast amount of data. While some of this data may be sensitive in nature, in that it contains personal or confidential information, much of it is in the public interest. Recent years has seen the emergence of Open Government Data (OGD) where governments are now actively making their data available in open and electronically accessible formats. The motivation for the production of such data includes a desire to increase transparency but also a desire to realise the economic potential associated with re-use of this data. A key usage area for this data to date has been within mobile applications where raw OGD is transformed into a consumable product. Making data available for re-use in this context introduces the concept of data quality in that the OGD being released must be of sufficient quality to allow for re-use by application developers. This dissertation proposes a set of quality guidelines to be applied to OGD to aid its utility within m...

Accessible Information: Advocating the Use of Technology for Individuals with Intellectual Disability on their Path to Individualised Services
(2012)
Moloney, Michelle
Abstract:
<p>Providing people with an intellectual disability (ID), opportunities for social integration have been shown to have a reliable positive influence on their well-being (Wehmeyer et al., 2006; Bunning, 2009). A large percentage of individuals with ID are unable to read and write. For this reason in order for the person to make an informed choice the person needs to have good information presented in a way that they can understand. They may need to see tangible visual aids (video, role play, film, photographs). It may need to be demonstrated to them a number of times. This assists a person in making choices and decisions so that they can actively participate not just in their own lives but in the community. Otherwise the person cannot make the decision, and other people are making it for them. Therefore this research will investigate the viability of developing an internal webbased learning and communication tool for people with an ID. The tool will focus on providing accessibl...

Effective Knowledge Management System Implementation in Small Organisations.
(2012)
Nicholl, Orna
Abstract:
<p>Much of the key research in the field of Knowledge Management carries an inherent set of assumptions as to the nature of the organisations under investigation, such as the fact that the organisation is a large one. As a consequence of this, Knowledge Management papers tend to focus on the distinctions such as: management-led initiatives versus grassroots initiatives, and the importance of inter-departmental communications, but for smaller organisations these types of issues are minimised or completely absent. This project will look at models and techniques from the existing body of Knowledge Management literature (with its focus on larger organisations) and look at how these approaches may need to be modified for smaller organisations and teams. A number of techniques will be investigated, and a smaller number will be fully developed specifically for the (small) target team based on their needs. A preliminary survey will be undertaken of employees in organisations with alre...

E-learning and Knowledge Management: The development of an E-Learning System for Organisational Training
(2012)
Muhire, Alan
Abstract:
<p>Information technology has major role in most successful companies and organisations around the world, most companies are using IT to reduce operation cost, while improving customer service by providing service twenty four hours, seven days a week and improving communication that helps keep pace with competitors. In most companies and organisation training is a process carried out on a regular basis; the quality of training offered to employee will be reflected on how knowledgeable the staff will become resulting in the organisation becoming more successful. As organisations and companies are currently interested in improving knowledge management, employees are equally working hard to improve their knowledge and skills to ensure their job security, it is important to evaluate tools and techniques that can be used to achieve this objective. This research looks at knowledge transfer and knowledge sharing processes through the development of an e-learning system which consider...

Testing Mobile Web Applications for W3C Best Practice Compliance
(2012)
Mee, Sean
Abstract:
<p>Adherence to best practices and standards when developing mobile web applications is important to achieving a quality outcome. As smartphones and tablet PCs continue to proliferate in the consumer electronics market, businesses and individuals are increasingly turning from the native application paradigm to HTML 5-based web applications as a means of software development and distribution. With an everincreasing reliance by users on the correct functioning of such applications, the requirement for stringent and comprehensive quality assurance measures is also brought sharply into focus. This research investigates the increasing trend towards mobile web application development in the mobile software domain, and assesses the requirement for an automated approach to best practice validation testing for mobile web applications. Contemporary approaches to automated web application testing are examined, with particular emphasis on issues relating to mobile web application tests. T...

Liu, Chong
Abstract:
<p>With the emergence of a knowledge society and of information technology, knowledge has become a key resource to develop a sustained economy. It is a vital word in the Knowledge Management area (Awad & Ghaziri, 2004). Knowledge Management has also become vital to help knowledge organizations seek a competitive advantage. It also encourages members of organization to share knowledge and improve the organization‘s efficiency, performance, and competitiveness (Shin, 2004). Therefore, an increasing number of organizations have realized the necessity of knowledge management. Especially, the Higher Education Institute (HEI) as the extraordinary ―business‖ will be suitable for implementing knowledge management approaches and activities to have a competitive advantage in the ―education market‖. The head of HEI realizes the challenges that knowledge organization brings. The challenges include: the intensive knowledge needed to manage; activities involved in knowledge creation, di...

(2012)
Kuanyshev, Tair
Abstract:
<p>The aim of this project is to build a recommender system for an online website based on an empirical study using real-world data. The real world data was taken from the website Www.kiwi.kz which is an online video sharing website, providing online video, broadcast and radio to users since 2009. The research problem sought to develop the most suitable recommender system for an online video sharing website and to evaluate the effectiveness of this model on the real world data. This research attempts to develop the recommender system which will suggest possibly interesting video clips for users on an online video sharing website. It also proposes methods and techniques that can be used to implement recommender systems and evaluate its effectiveness on an offline experiment. This project is based on performing an empirical evaluation to establish whether a recommender system can be developed that will predict whether people will like a particular video.</p>

Hear3D: A Study Of Spatial Sounds Effect On Language Learning
(2012)
Cregan, Brendan
Abstract:
<p>Spatial sound is the manipulation of audio to add the illusion of position to the source of the sound, i.e. making sounds seem to originate from behind you or from different points around a room. Headphones must be used to achieve the optimum level of 3D sound. At any time over half a billion people are learning languages with the aide of audio which is why and the study of the effect or potential effects that the spatial sounds have on language learning is particularly interesting. If the application of spatial sounds to educational audio clips could be shown to have a positive effect by, for example, improving the knowledge retention of the listener it could provide an interesting insight into future language learning course development. Equally, if the effect had a negative effect on the listener’s learning capacity it could also provide guidelines for the creation of high quality educational audio content. For the purposes of this dissertation Hear3D an application that...

Using Grounded Theory to Develop a Framework for Software Testing Best Practice in a Telecommunications Company
(2013)
Hendrick, David
Abstract:
<p>Software testing is a key part of the software development process, irrespective of the development methodology being followed. Estimates suggest that testing can account for more than 50% of the cost of a software development project. However, the cost of inadequate testing or verifying software can be far greater; this can result in losses that could total more than 10% of an organisation’s turnover. It is clear that software testing is essential; but while many companies implement different forms of testing, there is often no structure or best practice followed to this testing. There appears to be a gap in terms of research into software testing best practice. It has been shown in previous research that qualitative research methods can be used successfully when conducting research in the software engineering domain. In particular Grounded Theory was seen as very suitable for research in this area. The basis of Grounded Theory is in the formation of a theory from the data...

Retaining the People Who Know Your Business Exploring Knowledge sharing as a tool to Improve Employee Retention in the Hotel Sector
(2013)
McKenna, Vincent
Abstract:
<p>The retention of core workers in the hotel/hospitality sector is a key challenge for human resource management, organisational strategies and operational effectiveness. The purpose of this research was to investigate and evaluate the impact of the introduction of knowledge sharing tools/techniques and change in work practice on the retention attitudes of knowledge workers in two context specific environments. Problems relating to the retention of knowledge workers are not confined to Ireland and are shown in this project to be a global phenomenon.</p> <p>This research project is based on a knowledge audit of core knowledge workers/assets in two context specific environments and that knowledge audit allowed for the construction of a work/training rotational matrix, a new concept developed by this author. The work/training rotational matrix in this project is simply used as a visualisation for the recommendations flowing from the knowledge audit.</p>

O'Reilly, Sarah
Abstract:
<p>Prior research has argued that there is no one best approach to evaluating web accessibility and proposes the adoption of multiple approaches. Following these proposals this research used three different approaches for evaluating accessibility on websites for accessibility to older persons with sight difficulties as there are advantages and disadvantages to each approach. Approached used included: (1) Using automated tools to determine accessibility, which looks at the code of websites to get a general overview of accessibility issues. (2) Manually looking at the design, code and also how it might impact the user. This involved a manual assessment of each of the websites and comparison to the WCAG 2.0 guidelines (3) the third aspect of Web 4 accessibility is looking at the visual, thinking skills or cognition required by the user to access the website. The user testing evaluation method involved participants completing tasks on each of the three websites while participants ...

Can a Self Assessement Tool for Environmental Controls which has been Informed by Users be of Benefit to Potential Users
(2012)
Loughran, Sean
Abstract:
<p>This dissertation looks at the area of environmental control systems (ECS) also known as electronic aids for daily living for people with disabilities. These systems allow an individual with a disability to control devices such as a television, music player, telephone as well as a door, window or curtain controllers. A self-assessment tool was developed for potential users, which was informed by the feedback of (i) users who use or who have used environmental control systems, (ii) Enable Ireland staff who were involved in the service delivery of ECS and (iii) companies who install ECS for individuals with disabilities. These stakeholders were interviewed by a guided interview based on the research on assistive technology models. Results of interviews informed the self-assessment tool development. After the self-assessment tool was developed it was evaluated by potential users to see what benefits it had for potential users.</p>

Towards Universally Designed Assistive Technology E-Learning
(2012)
O'Keeffe, Karl
Abstract:
<p>The aim of this dissertation is to provide Assistive Technology (AT) professionals involved in the area of education and training with a set of reusable technological tools and techniques that will enable them to increase the reach, efficiency, effectiveness and accessibility of their training through online delivery. There are a number of broadly accepted reasons why an organisation in any field might choose to make training available online or partially online (blended) rather than relying on traditional face to face methods. Of the four considered here and mentioned above, accessibility is the biggest concern in the context of AT. It is essential that an AT course follows accessibility best practice and in terms of education this means adhering closely to the principles of Universal Design for Learning (UDL). Through an extensive literature review the intrinsic properties of AT that might influence its delivery as e-Learning will be examined, followed by a review of prev...

Optical Reading and Playing of Sound Signals from Vinyl Records
(2007)
Hensman, Arnold; Casey, Kevin
Abstract:
<p>While advanced digital music systems such as compact disk players and MP3 have become the standard in sound reproduction technology, critics claim that conversion to digital often results in a loss of sound quality and richness. For this reason, vinyl records remain the medium of choice for many audiophiles involved in specialist areas. The waveform cut into a vinyl record is an exact replica of the analogue version from the original source. However, while some perceive this media as reproducing a more authentic quality then its digital counterpart, there is an absence a safe playback system. Contact with the stylus provided by a standard turntable causes significant wear on the record (or phonograph) over time, eventually rendering it useless. Couple this with the historic value and an abundance of such vinyl media, and the need for a non-contact playback system becomes evident. This paper describes a non-contact method of playback for vinyl records which uses reconstructi...

Robust Digital Video Watermarking using Reversible Data Hiding and Visual Cryptography
(2013)
Kumar, Manoj; Hensman, Arnold
Abstract:
<p>Watermarking is a major image processing application used to authenticate user documents by embedding and hiding some authenticated piece of information behind an image, audio or the video file. For example, copyright symbols or signatures are often used. Our proposed work is to develop and implement an improved layered approach to video watermarking. The traditional watermarking approach tends to embed an entire watermark image within each video frame or within random video frames to give the appearance of a hidden watermark to the casual observer. This work proposes a more efficient and secure approach to perform watermarking, by using sub image classification. That is to say, selected frames only will contain a fractional number of pixels from the watermark image. We take k bits from the watermark and store then within a video frame, depending on the size of that watermark image. Our algorithm is capable of hiding high capacity information over video frames. The novel ap...

Judging Emotion from Low-pass Filtered Naturalistic Emotional Speech
(2013)
Snel, John; Cullen, Charlie
Abstract:
<p>In speech, low frequency regions play a significant role in paralinguistic communication such as the conveyance of emotion or mood. The extent to which lower frequencies signify or contribute to affective speech is still an area for investigation. To investigate paralinguistic cues, and remove interference from linguistic cues, researchers can low-pass filter the speech signal on the assumption that certain acoustic cues characterizing affect are still discernible. Low-pass filtering is a practical technique to investigate paralinguistic phenomena, and is used here to investigate the inference of naturalistic emotional speech. This paper investigates how listeners perceive the level of Activation, and evaluate negative and positive levels, on low-pass filtered naturalistic speech, which has been developed through the use of Mood Inducing Procedures.</p>

An Investigation into the Causes and Effects of Legacy Status in a System with a View to Assessing both Systems Currently in use and Those Being Considered for Introduction
(1999)
O'Byrne, Patricia
Abstract:
<p>This dissertation analyses the area of legacy systems and determines the effects that are exhibited in legacy systems, presenting them in a legacy effect determination framework, so that management can ascertain whether the system they have is a legacy system. An analysis of legacy causal criteria is carried out, resulting in a table of legacy causes. A new definition of legacy systems is put forward, by defining legacy status as a status held by a legacy system. “A system exhibits legacy status if it is deficient in terms of its suitability to the business, its platform suitability or application software quality, with the effect that its asset value diminishes, as does its ease of operation, maintenance, migration or evolution.” Legacy status is split into three dimensions, that of system suitability, platform suitability and software quality. These dimensions are analysed and practices shown that enable good quality within them. Solution strategies for handling legacy sy...

A Study of SIP Based Instant Messaging Focusing on the Effects of Network Traffic Generated Due to Presence
(2008)
McKeon, Finnian
Abstract:
<p>The increasing usage of Instant Messaging(IM) applications worldwide continues to grow year on year. However, larger numbers of users creates problems with greater network traffic, interoperability and proprietary protocol dependence. Network traffic due to presence information being exchanged between users and servers needs to be considered, but is it possible to estimate or measure this traffic? There have been very few studies performed on the impact of presence traffic. The purpose of this research is to implement a SIP/SIMPLE network environment that will allow the evaluation of key metrics such as the latency and throughput of the network under a number of scenarios. It will be shown that the amount of network traffic generated due to presence subscriptions can grow large, and the effects of this on network performance will be analysed. From this analysis, it will be shown that SIP/SIMPLE presence traffic has a steady, predictable impact on the performance of the netw...
