The invention can significantly reduce the DC-link capacitance in general power electronic systems through the use of a series voltage compensator. The lifespan of electrolytic capacitors, a component of power electronic systems, is cut short when ambient temperatures rise, and therefore many electr.....

The dual-polarized patch antennas designed by CityU are compatible with L-shaped probes, which are also invented by CityU. The L-shaped probe is connected to the input port, and part of it is parallel to the patch. The isolation enhancement technique inherent in this invention can reduce the strong .....

iSA is a user-friendly yet powerful 2D structural analysis package that supports modelling with a “drawing” graphical user interface or by using template wizards for generating structurally complicated models in minutes. Also available are comprehensive databases of materials, standard or user-defin.....

Vehicle emission is a significant source of air pollution problem in urban areas. Traditional test methods are often limited by high cost, low efficiency and limited functionality, preventing their urban applications. The On-road Plume Chasing and Analysis System (OPCAS) provides an alternative and .....

Cubic boron nitride (cBN) is only second to diamonds in terms of hardness and thermal conductivity. However, cBN films are usually thinner and are grown on many substrates, which undermine their hardness, adherence and stability. The multilayer coating (MLC) developed by CityU overcomes the problems.....
