Vocal resonances in speech: rapid, precise measurements of how tract resonances vary with time, with applications to speech and language training. This project will track dynamically with significant precision the resonances of the vocal tract which produce much of the phonetic information in speech and important features of accent. The information and technology developed will be useful for speech science, benefiting speech synthesis, speech training and language acquisition.
Fracture-Resistant Highly Insulating Vacuum Glazing. Vacuum glazing can provide thermal and sound insulation for windows that achieve the benefits of double glazing without the increased thickness by incorporating a vacuum space between two sheets of glass. The gap is maintained by pillars under high compressive stress due to atmospheric pressure. In this project, we will study the effect of pillar designs and materials on the U-value and the mechanical performance of these complex structures.

Vacuum glazing can provide thermal and sound insulation for windows that achieve the benefits of double glazing without the increased thickness by incorporating a vacuum space between two sheets of glass. The gap is maintained by pillars under high compressive stress due to atmospheric pressure. In this project, we will study the effect of pillar designs and materials on the U-value and the mechanical performance of these complex structures. Detailed simulations and measurements of stress distributions in the pillars, edge seals and glass sheets, under static and dynamic loading conditions, will allow us to develop glazing structures with greatly increased mechanical strength.Read moreRead less

Beam steering by Huygens metasurfaces for sensing applications. This project aims to develop steerable radar systems for navigation sensors and surround monitoring in vehicles, using antennas operating in the millimetre-wave range, which have improved resolution and maintain long sensing distances. The boom in radar sensing technologies used for safety and comfort in cars has stimulated the need for cost-effective directional antennas for beam steering in sensing applications. This project will use the recently discovered concept of Huygens metasurfaces, which enable cost-effective devices with low transmission losses and strong tuning of beam-steering angle. The wider availability of such radars is expected to enhance collision prevention systems, adaptive cruise control and ultimately help create self-navigating cars.Read moreRead less
