Adaptive knowledge extraction and loose semantic coupling in multimedia publish/subscribe overlay networks
(NUI Galway, 2022-06-14)The primary use of communication networks today has shifted towards content dis-tribution despite being originally designed for conversations between communicatingendpoints. The massive amounts of data ... -
Advances in the estimation of the reproduction number from compartmental models using contemporary Monte Carlo methods
(NUI Galway, 2024-03-08)The reproduction number represents the average number of secondary cases generated by a primary case. If the population is completely susceptible, it is referred to as the basic reproduction number (<0) and theoretically ... -
An analysis of internal attacks on PTP-based time synchronization networks
(NUI Galway, 2021-12-21)The IEEE 1588 precision time protocol (PTP) is very important for many industrial sectors and applications that require time synchronization accuracy between computers down to microsecond and even nanosecond levels. ... -
Applying machine learning towards automating resource management in cloud computing environments
(NUI Galway, 2021-01-28)Over the last number of years there has been high acceleration and widespread adoption of cloud based services by many different industries to improve the scalability and reliability of their services while also reducing ... -
Building semantic models and knowledge graphs for intelligent smart manufacturing applications
(NUI Galway, 2024-04-04)Industry 4.0 (I4.0) (or smart manufacturing) is a new era in the industrial revolution that emphasises machine connectivity, automation, and data an alytics. This revolution has led to the creation of production lines ... -
Coevolutionary spatial game theory: The impact of abstention and dynamic networks on the evolution of cooperation
(NUI Galway, 2020-01-15)Since the dawn of evolutionary game theory, the standard models in evolutionary dynamics have been developed under the assumption of a well-mixed population where agents (individuals) can interact with all the other agents ... -
Contextualised sentiment analysis in the financial domain
(NUI Galway, 2021-07-02)Sentiments and beliefs play an important role in actions and decisions in a market environment; for example, people disliking a brand will tend to avoid products of it or people aiming to reduce their carbon-dioxide footprint ... -
Contributions towards 3D synthetic facial data generation and 3D face analysis with weak supervision
(NUI Galway, 2024-03-11)Facial analysis tasks are of pivotal importance in social interaction, thus gaining extensive attention among the scientific community. With the increased popularity of deep learning models and the availability of ... -
Cross-lingual natural language processing with linguistic typology knowledge
(NUI Galway, 2023-10-04)State-of-the-art approaches to most Natural Language Processing (NLP) tasks have achieved near human performance. This recent progress has positively impacted millions of lives and businesses around the world. However, ... -
Dashboards for supporting cancer care in value-based healthcare context – Information needs, design principles and acceptance
(NUI Galway, 2021-09-19)Improving the value of care is central to the value-based healthcare model. This model emphasises the active role of patients in decision making and providing them with the information they require during the different ... -
Decoding the kinematic and ionisation structure of axisymmetric nebulae
(NUI Galway, 2021-08-04)The aim of the thesis was to develop a code and pipeline for generating 3D photoionisation models of axisymmetric nebulae to better understand their ob- served structure and composition. This was achieved through a new ... -
Denial of Wallet: Analysis of a looming threat and novel solution for mitigation using image classification
(NUI Galway, 2023-08-22)Serverless Computing is a powerful cloud-based architecture for the creation of applications. It boasts incredible scalability by running processes on a vast network of edge nodes. It decreases the time to deployment, ... -
