(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2014)This project looks at the problem of the capture or synthesis of acoustic events in reverberant spaces and their subsequent plausible reproduction in a virtual version of the original space, otherwise known as a Virtual ... -
Optimum stability in control system design
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2007)This thesis develops for the first time a general approach to the design of control systems that emphasizes optimum system stability as the primary design criterion. The design method is to select controller parameters ... -
Perception of true linear self-motion using vestibular stimulation in humans : a mathametical electrophysiological analysis
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2013)In humans, the percept of motion is a combination ol multiple sensors modalities, primarily involving vestibular, visual and somatosensory (Ohmi, 1996). The ability to properly perceive motion enables us to function normally ... -
Perceptually motivated audio time-frequency analysis
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2001)Fourier analysis has long been an indispensable tool for the investigation of signals whose frequency content does not change with time. It has likewise been of fundamental importance in engineering for the study of linear ... -
Predicting speech intelligibility

Probabilistic Behavioural Modelling of Non-Linear Devices
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2023)Behavioural device models are black-box models which depend only on measured data and are independent of the underlying physics behind the working of the device. Behavioural device models are widely used to model non-linear ... -
Probing the neural mechanisms of adult-onset isolated focal dystonia
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2018)Adult onset isolated focal dystonia (AOIFD) is inherited in an autosomal dominant manner with a reduced penetrance of 12-15%; cervical dystonia (CD) is the most common phenotype in northern Europe. It is believed that the ... -

Quasiprobability density diffusion equations for the quantum Brownian motion in a potential
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2007)Wigner's [E. P. Wigner, Phys. Rev., 1932, 40, 749] representation of the density operator as a c-number quasiprobablity distribution in phase space allowing quantum mechanical averages involving the density matrix to be ... -
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 ... -
Radio Access Network and Spectrum Sharing in Future Mobile Networks
(2016)Future mobile networks will be characterized by wide-spread resource sharing, and a more nuanced view of what it means to offer a mobile service. The traditional view of a mobile network as a system that simply delivers ... -
Re-Engineering Rate Distortion Optimisation in Modern Video Codecs Using a Per Clip Approach
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2023)The majority of internet traffic is video content. This drives the demand for video compression to deliver high quality video at low target bitrates. Optimising the parameters of a video codec for a specific video clip ... -
Real-time out-of-band interference reduction for OFDM-based systems
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2012)Interference reduction for OFDM-based systems is of increasing interest in new technologies such as dynamic spectrum access networks. In the past decade, many approaches have been proposed for reducing the interference of ... -
Reconfigurable OFDM systems
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2005)Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier wireless transmission technique. OFDM is used for robust, high quality and high data-rate music, voice, images, video, news and data broadcasts. It is ... -
Reconfigurable software radio systems
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2004)Software radio has been heralded as a significant evolutionary step for wireless technology as it allows dedicated analogue radio hardware to be replaced with flexible digital signal processing. Due to current technological ... -
