High-level event detection in broadcast sports video
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2005)This thesis investigates semantic analysis of broadcast sports footage. A domain dependent sports video model is proposed. Under this model, the game semantics can be derived according to their relationship with the ... -
The impact of visual speech on neural processing of auditory speech
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)When we listen to someone speak, seeing their face can help us to understand them better, especially when there is background noise or other people speaking at the same time. Research examining the neural processes underlying ... -
Intermolecular and interlayer interaction in chiral smectic-C liquid crystals
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2008)The molecular and interlayer interactions in smectic-C phases have been investigated in detail. This topic is one of the less well established subjects in the field of liquid crystals. Various new physical phenomena were ... -
Investigating cortical encoding of auditory space & motion in humans using EEG
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)This work uses a novel linear regression-based framework together with scalp recorded electroencephalography (EEG) to study various aspects of spatial hearing in humans. In our first study, we showed that in an acoustic ... -
Investigating the Neural Correlates of Cervical Dystonia and Temporal Discrimination using Neuroimaging based Computational Modelling and Multimodal Pattern Recognition
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)Movement disorders, such as Parkinson s disease and Dystonia, have traditionally been considered as disorders of impaired motor control resulting predominantly from dysfunction of the Basal Ganglia. However, there has been ... -
Investigating the Neural Correlates of Speech Processing & Selective Auditory Attention using EEG
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)Speech comprehension is a remarkable human ability. Most normal-hearing people are adept at attending to a speech stream even amidst a noisy multi-talker background and parsing the layers of information it contains in ... -
Investigating the temporal dynamics of auditory processing and selective attention using continous and ecologically valid stimuli : a neural engineering approach
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2011)Auditory Evoked Potentials (AEPs) are a measure of the neural activity in response to auditory stimulation and are used in many clinical and research applications. They are obtained from the electroencephalogram (EEG) by ... -
Investigation of Objective Neurophysiological Measures of Auditory Temporal Processing Abilities and Their Applicability in Cochlear Implant Rehabilitation
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2019)Speech is the most important form of human communication. For people affected by disabling hearing loss, speech information may become unavailable causing social isolation and cognitive decline. People with mild to profound ... -
Isolating neural indices of continuous speech processing from multivariate neural data
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2017)The human ability to understand speech is underpinned by a hierarchical auditory system whose successive stages process increasingly complex attributes of the auditory input. To produce categorical speech perception, it ... -
Joint caching and communication for future wireless networks
Recently, caching the most popular content at network edges has emerged as a promising technique to avoid serving all requests from the core network through highly congested backhaul links. From the caching perspective, ... -
Large electroclinic effect and stability of chiral smectic liquid crystals
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2009)Large electroclinic effect in the smectic-A* phase and stability of smectic-C* variant phases are investigated in detail. Investigation of large electroclinic effect in the smectic-A* phase is one of the recent topics, and ... -
Massive MIMO and Millimetre Wave Technologies: Design, Application and Integration with ML Techniques for 5G and Beyond Networks
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect.

Massive MIMO technology for next generation of wireless networks
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)Large scale antenna or massive multiple input multiple output (MIMO) systems are one of the key enabling technologies for fifth generation (5G) of wireless communications networks and beyond. This technology offers huge ... -
Mathematical processing of in-vivo electrophysiological data with applications to implanted electrode recordings
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)Neurons are the principal cellular elements that underlie the function of the nervous system, which includes the brain, spinal cord, and peripheral ganglia. These electrically excitable cells process and transmit information ... -
Methods of signal processing applied to speech and language for objective assessment of cognitive function in ageing and psychiatry
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2014)Ageing is associated with a change in cognitive function. Impaired cognitive function is the biggest limiting factor to independence in older adults. Cognitive decline does not appear suddenly, but occurs gradually over ... -
