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 ... -
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 ... -
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 ... -
Microphone array processing techniques for classroom-based videoconferencing
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2008)This thesis is concerned with the design and development of microphone-array-processing techniques for videoconferencing applications in classroom environments. We argue that, in such environments, it is advantageous in ... -

Numerical methods for the high speed solution of integral equations in wireless communications
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2001)This thesis investigates the the appropriateness of integral equations for use in determining electric field coverage over sub-urban terrain which is illuminated by an arbitrarily placed transmitter. Sub-urban terrain is ... -
Optimised real-time rendering of auditory events in immersive virtual environments
(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 ... -
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 ... -
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 ... -
