Hamda Ajmal: "Using Data Analytics to Refine Structure of DBN Derived from Mathematical Models"


Abstract: Research has been done previously to develop probability-based framework which exploits existing domain knowledge in the form of mathematical models and uses real-time data streams to individualise model parameters. The focus of this current research is to design and develop new machine learning algorithms to inductively learn probabilistic models; specifically Dynamic Bayesian Networks (DBNs) by taking the DBN derived from a mathematical model a starting point. It is expected that the new learned structures will be able to perform better than the original ones.


Mahmoud Elbattah: "Multi-Perspective Modeling and Simulation Approach for Healthcare Planning Applied to Hip Fracture Care"


Abstract: The aging population of Ireland implies an inevitable need for patient-centred healthcare strategies that can keep pace with the consequent foreseen challenges. The research project aims at modeling the necessary components towards developing a nation-wide plan for the prevention and prediction of fall injuries and hip fractures, as an exemplar of elderly healthcare services. The project is being developed in collaboration with the AFFINITY (Activating Falls and Fracture Prevention in Ireland Together) program, overseen by the State Claims Agency and the HSE.


Both speakers are PhD students in the IT discipline, under the supervision of Dr Mike Madden (Hamda) and Dr Owen Molloy (Mahmoud).

Optimizing the QoS of VoIP Applications over WiFi through the use of Synchronized Time

‌‌‌IT Research Seminar

"Optimizing the QoS of VoIP Applications over WiFi through the use of Synchronized Time".

Padraig O Flaithearta

Time: Thursday, 16th April 2015, 11am - 12pm

Venue: room IT125G (IT building, ground floor)



The Internet has evolved to a stage where the number of Internet enabled devices exceeds the global population. With much of the required connectivity over wireless, contention for bandwidth is an important issue which has to be addressed. In this context, applications that have certain Quality of Service (QoS) requirements must be protected. WiFi-enabled mobile devices such as smartphones and tablets are commonly used by both personal and business users for Voice over IP (VoIP) communications, while also supporting conventional data applications such as email, file transfer and web access. Previous research has shown that time synchronized endpoints can provide better QoS by calculating accurate Mouth to Ear (M2E) delays, and using this information to better inform buffer playout strategies. The IEEE 802.11e protocol extends 802.11 by providing different traffic priorities based on traffic type. However, it cannot distinguish between traffic streams within the same category. This research has developed a real world proof-of-concept test-bed that utilizes an Access Point (AP)-centred mechanism for further distinguishing between streams within 802.11e categories. Results are presented that correlate well with previous NS-3 based simulations.

Guerrilla Analytics

‌‌‌IT Research Seminar

Guerrilla Analytics

Dr Enda Ridge

Monday, 23rd February 2015, 3-4pm AC003 (D’Arcy Thompson Lecture Theatre) National University of Ireland, Galway


Doing data science is difficult. Projects are typically very dynamic with requirements that change as data understanding grows. The data itself arrives piecemeal, is added to, replaced, contains undiscovered flaws and comes from a variety of sources. Teams have mixed skill sets and tooling is often limited. Despite these disruptions, a data science team must get off the ground fast and begin demonstrating value with traceable, explainable, tested work products. This is when you need Guerrilla Analytics.

In this talk, you will learn about:


  • The Guerrilla Analytics Principles: simple rules of thumb for maintaining data provenance across the entire analytics life cycle from data extraction, through analysis to reporting.
  • Reproducible, traceable analytics: how to design and implement work products that are reproducible, testable and stand up to external scrutiny.
  • War stories: practice tips on actual project challenges encountered in consulting, pre-sales and research.
  • Preparing for battle: how to set up your team's analytics environment in terms of tooling, skill sets, workflows and conventions.

Time-Aware Systems and the Internet of Things (IoT)

Time-Aware Systems and the Internet of Things (IoT)

Seminar Slides:Time-Aware Systems

Dr. Marc Weiss

Formerly NIST Colorado US

Friday 31st October 2014, 1pm-2pm, Room IT207 (IT Building)

Trillions of Euro in growth are forecast over the next decade as the Internet becomes Industrialized. Companies like GE, AT&T, Cisco, IBM Intel and others are investing in an "Industrial Internet." A Public Working Group with co-chairs from NIST, NUIG, and National Instruments is developing a Framework and Reference Architecture for Cyber-Physical Systems: networked systems that sense, compute and control. A new initiative has begun called Time-Aware Applications, Computers and Communications Systems (TAACCS). The U.S. National Science Foundation has funded research on Timing in the IoT called the Roseline Project. With computing and networking optimally developed to disconnect from the physical layer, optimal timing, which comes as a physical signal, is at odds with modern data systems. Yet, improved timing methods will be critical for this massive growth predicted. This seminar discusses the current state-of-the-art in timing systems, and a way forward to further develop Time-Awareness in crucial elements to make timing a first-class citizen in the IoT.

Dr. Marc Weiss has worked at NIST (the U.S. National Institute of Standards and Technology--formerly NBS, the National Bureau of Standards) since 1979, specializing in time transfer techniques. Specific work has included: developing GPS since 1980, Relativity problems applied to clocks, optimal statistics for clocks, creating and leading a workshop on synchronization in telecom, and more recently focusing on sync and control systems in other networks. He received his Ph.D. in Mathematical-Physics from the University of Colorado in 1981.

Topic: Open education and digital identities

Time: Thursday, 6th February 2014, 11:00-12:00.
Location: Seminar Room THB-G010 (James Hardiman Library Extension)

Speaker: Catherine Cronin

Topic: Open education and digital identities

“I don’t think education is about centralized instruction anymore; rather, it is the process [of] establishing oneself as a node in a broad network of distributed creativity.”
- Joi Ito (2011)


This presentation will explore emerging open education practices and their effects not only on learning and teaching, but on our multiple and overlapping identities as networked scholars, educators, students, and citizens. We are in the early days of large-scale open education. The boundaries continue to blur between real and virtual spaces, formal and informal learning, educators and learners. Open, participatory and social media are enabling new ways of learning and new forms of education (MOOCs anyone?). While the traditional higher education model is focused on centralized expertise, the individual learner, and competition, higher education is currently engaged in the process, albeit unevenly, of moving towards more distributed expertise, facilitation of networked learners, and openness. This presentation will consider the concept of digital, networked identities in the context of open education, with a particular focus on us as educators and our interactions with students in both bounded and open online spaces.

Speaker bio: Catherine is academic coordinator of IT Online programmes and lecturer in Professional Skills in the BSc CS+IT programme. Catherine’s work focuses on online and open education, digital literacies, and social media in education. In addition to her teaching and research in HE, she works with schools and community groups exploring these areas. She is currently pursuing a Ph.D. in the area of open education and digital identity practices. She holds a B.Sc in Mechanical Engineering, M.Eng. in Systems Engineering, and M.A. in Women’s Studies where her dissertation topic was gender and technology.
