The Feedback Cello is a new electroacoustic actuated instrument in which feedback can be induced independently on each string. Built from retro-fitted acoustic cellos, the signals from electromagnetic pickups sitting under each string are passed to a speaker built into the back of the instrument and to transducers clamped in varying places across the instrument body. Placement of acoustic and m...

The crucial problem of construction debris is of increasing concern in Hong Kong. In the construction industry, the electrical and mechanical (E&M) installations in the infrastructure, whether buildings, tunnels or dams for example, are some of the major and usually complex components. Difficulty in coordinating the various trades affects productivity in general, and has a major impact on the q...

In this paper an analysis of different designs of traction transformers is given. The paper describes three-limb transformer design for 7.5 MVA and 10 MVA units and two-limb transformer design for 15 MVA and 16 MVA units. Paper also represents noise level measurement results and sound intensity frequency spectrum for 16 MVA unit. Based on results of measurements taken during heat run test on tr...

While current atmospheric Cherenkov installations consist of only a few telescopes each, future installations will be far more complex. Monte Carlo simulations have become an essential tool for the design and optimisation of such installations. The CORSIKA air-shower simulation code and the sim_telarray code for simulation of arrays of Cherenkov telescopes have been used to simulate several can...

For my doctoral research I am exploring the potential and challenges of large display information visualizations in public settings such as museums. The combination of information visualization as a means to represent abstract data and interactive display technologies, shows great potential for engaging visitor experiences. However, public spaces with their diverse audience and distractions int...

This paper discusses design issues in the development of playful outdoor interactive installations featuring kinesthetic interaction and immersive music experiences. The research is based on the development and evaluation of the novel SwingScape installation, which is a permanent installation at an urban playground. The objectives of SwingScape are to encourage physical activity as well as crea...

During the last couple of decades our perception of what constitutes a good learning environment has changed. Thanks to the use of technology, education is evolving from a passive model towards a more productive model, where students generate knowledge, teach each other, and collaborate on activities that make learning fun and interesting. In some previous works we have adopted this attitude: c...
