Deep Cross-Modal Alignment in Audio-Visual Speech Recognition
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)Modern studies in cognitive psychology have demonstrated that speech perception is a multimodal process, as opposed to a purely auditory one with visual carryover as in the classic view. This led researchers to investigate ... -
Deep Interactive Image Matting
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2022)Image Matting for Compositing is the cutting of an object from an image for background replacement. It is an interactive process fundamental to image editing. Useful matting algorithms both reduce the amount of interaction ... -

Development of audio-based signal processing methods to objectively assess patient adherence in respiratory medicine
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2018)Over four million people die every year from chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). There is no cure currently available for these diseases; however, they may be ... -
Development of neural engineering methods for objective assessment of cognitive processing based on Gait Data : an analysis of a truly nationally representative cohort of older adults
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2015)Knowledge of the brain substrates and neural networks at play during gait are not well understood. However, strong associations between gait and cognitive function have been found in literature. Examining this relationship ... -
Digital signal processing approaches to bird song analysis
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2017)The ability to automatically analyze bird vocalizations would provide major assistance to zoologists in their behavioral and ecological studies. Revisions of taxonomy need to be made in cases where a population of species ... -
Dipole-Dipole Coupling and Other Interaction Effects in Polar Dielectrics and Magnetic Relaxation of Single Domain Ferromagnetic Nanoparticles
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)The main purpose of this thesis is to provide the precise details of the very onerous calculations underlying our two published papers [1] and [2]. Thus, the latter can be better understood and utilised later for future ... -

This thesis is concerned with meaning-making in sonification. It examines how meaning emerges during sonification listening through the lens of embodied cognitive ... -
Enabling Adaptable Future Networks: Trade-Offs and Resource Allocation Problems
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)In this thesis, we illuminate the various trade-offs arising from the trend towards customisable networks, and propose resource allocation procedures to balance these trade-offs and facilitate the necessary coexistence of ... -
Enabling coalitions between Independent Networks
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2015)The ways in which networks are built, owned and controlled have evolved in recent years. The traditional model, of a single entity owning or somehow participating in the entire telecommunications value chain, has begun to ... -
Enabling cognitive radio experimental research
