Railway condition monitoring is one of crucial factors to ensure safe and cost-effectiveness of train operation. A fiber Bragg grating sensors based real-time train wheel condition monitoring system has been developed and reported by our team. In the system, the condition index (CI) is generated to indicate wheel condition. To further verify the system is reliable. This paper reports, as case studies,...
Laboratory experiments are always vital for a university student in electronic engineer to improve her/his practical skill. However, because of unit cost and availability, student may not get opportunity to use the equipments, particularly the latest industrial equipments, in their experiments. For this reason many graduates require time to adapt to real industrial technology when they leave university...
Cognitive radio is a highly promising technology to efficiently solve the spectrum scarcity challenge and harmonize the networks heterogeneity. Through component spectrum sharing, secondary users (SUs) are able to opportunistically access licensed spectrum shared with the primary system. In the literature, spectrum sharing is normally investigated on the basis of the assumption that the spectrum sensing...
