The public transportation system is crucial in alleviating urban congestion. The widespread of smart card automated fare collection (AFC) system produces massive data recording passengers’ day-to-day transport dynamic, which provides unprecedented opportunities to researchers and practitioners to understand and improve transit services. This project aims to make full use of the transit operational data (mainly smart card data) to enhance transit services. The main body of the research project is spatiotemporal behavior patterns mining.
Ultra-low frozen food temperatures between -30°C to -60°C are important when shipping high value seafood products to worldwide markets. Maintaining these temperatures using a traditional vapor compression refrigeration cycles becomes increasingly difficult as the span between desired cargo and external temperature increase. Solid CO2 has the capacity to sustain ultra-low frozen temperatures even during hot summer days using a passive, non-mechanical refrigeration system.
The HVDC Research Centre performs innovative research and development in high-voltage DC (HVDC) and power electronic technologies, instrumentation and simulation. HVDC is committed to finding new methods to improve efficiency in equipment usage and electric power flow. One such application is conversion and shaping of voltage waveforms, which is generally referred to as “modulation”.
