Data sharing has never been easier with the advances of cloud computing, and an accurate analysis on the shared data provides an array of benefits to both the society and individuals. Data sharing with a large number of participants must take into account several issues, including efficiency, data integrity and privacy of data owner. Ring […]

We study the statistical characteristics of radio environment noise, in particular focusing on spurious received power arising from adjacent channel interference, harmonics and wideband man-made interference. Unlike the majority of existing studies, our measurements enable a comprehensive study on frequencies ranging from 80MHz to 2.64 GHz instead of being focused on the properties of an […]

In recent years, renewable energy generators have been widely promoted in Ontario to offset their polluting counterparts. Due to connection cost of these generations, most of the renewable generation stations are connected to Hydro One transmission system at nearby HV transmission lines. However, the direct connections of the generation on the transmission line result in […]

Arrayed Waveguide Grating Router (AWGR) is currently one of the most promising components in data center interconnections for its passive and non-blocking feature. However, the scalability is restricted by the limited channel count. In this paper, by using multiple free spectral ranges (FSRs) of AWGR and couplers, we report a novel data center architecture with […]
