This is achieved through continuously ... -
Classification and segmentation methods with application in audio and acoustic signal processing
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2011)This thesis concerns the exploration of novel interactive educational resources to enhance literacy and language learning. The core system that arises from this research is called "ReciTell", which is a rich media based ... -
Relationship between the molecular interaction and the structure of the bent core liquid crystals in the nematic phase
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)The relationship between the molecular interaction and the molecular structure of the bent core mesogens in the nematic phase is investigated in detail. Various physical phenomena are observed and interpreted. -
Multiuser communications for next generation wireless networks
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2015)Orthogonal frequency division multiplexing (OFDM) has been the technology of choice for years in wired and wireless systems. However, it has some drawbacks that limit its use in the fifth generation of wireless communication ... -
Application of matrix methods for investigation of silicon based layered structures
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)This work is dedicated to the theoretical and experimental investigation of the influence of nano- and microstructuring of silicon systems on their linear optical response. The wavelengths of the light are comparable to ... -
Front-end analogue filter design for diagnostic electrocardiographic equipment
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2013)This thesis addresses the design of an analogue front-end filter for portable electrocardiographic equipment. The task of the filter is to eliminate as much out-of-band noise and interference as possible before the ... -
A semiclassical approach to quantum Brownian motion in Wigner's phase space
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2010)In this thesis, the recent semiclassical approach to quantum Brownian motion of Coffey et al. [Phys. Chem. Chem. Phys. 9, 3361 (2007)] is studied in detail. This approach is based on a semiclassical extension of Wigner's ... -
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 ... -
Design, fabrication and optical characterization of one-dimensional two- and multi-component photonic crystals based on silicon
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)The objective of this thesis was the design, fabrication and optical investigation of a novel type of one-dimensional photonic crystal structures for application in integrated Silicon microphotonics. This thesis reports ... -
Temporal discrimination thresholds as an endophenotype in adult-onset primary torsion dystonia
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)Adult onset primary torsion dystonia (AOPTD) is the most common form of dystonia and is an autosomal dominant disorder with markedly reduced penetrance. Most AOPTD patients therefore present as "sporadic" cases. Disordered ... -
Radical plumbers and playpumps
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2011)This thesis analyses the PlayPump, a water pump powered by a children's roundabout, which is designed for use in the developing world. The PlayPump is analysed as an example of 'design for development', an area of current ... -
An investigation of novel and next generation semiconductor and piezoelectric materials using Raman spectroscopic characterisation
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)Raman spectroscopy is an increasingly prevalent material characterisation technique and this work explored its application to several novel semiconductor and piezoelectric materials. Raman spectroscopy is non-destructive ... -
Amplifier front-end design in dry-electrode electrocardiography
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2011)This thesis presents an analytical approach to some key issues related to the design of biopotential amplifiers for use in long-term ambulatory recording of the electrocardiogram (ECG) employing pasteless or dry electrodes. ... -
Mapping theoretical and methodological perspectives for understanding speech interface interactions
(2019)The use of speech as an interaction modality has grown considerably through the integration of Intelligent Personal Assistants (IPAs- e.g. Siri, Google Assistant) into smartphones and voice based devices (e.g. Amazon Echo). ... -
Survival at the museum: A cooperation experiment with emotionally expressive virtual characters
(2018)Correctly interpreting an interlocutor's emotional expression is paramount to a successful interaction. But what happens when one of the interlocutors is a machine? The facilitation of human-machine communication and ... -
Attention-based audio-visual fusion for robust automatic speech recognition
(2018)Automatic speech recognition can potentially benefit from the lip motion patterns, complementing acoustic speech to improve the overall recognition performance, particularly in noise. In this paper we propose an audio-visual ... -
Multimodal continuous turn-taking prediction using multiscale RNNs
