Integration of renewable energy sources and demand response poses new challenges to system operators as they increase the uncertainty of the power supply and demand. Recently, robust optimization techniques are applied to the unit commitment problem with uncertainty as an alternative to the stochastic programming approaches. However, it remains challenging to solve the robust unit commitment model...
A mobile Social Network (MSN) is a type of wireless networks formed by people moving around carrying mobile devices. In this paper, we specifically study the MSNs that are formed impromptu, e.g. when people gather together for a conference, event, or festival. We refer to them as Impromptu Mobile Social Networks (IMSNs), which allow people to communicate in a lightweight fashion based on contact opportunities...

Cognitive radio is an exciting emerging technology that has the potential of dealing with the urgent requirement and scarcity of the radio spectrum. Although having multiple radio interfaces and available spectrum bands can generally increase the effective throughput, a problem arises as to what the best strategy to dynamically assign available bands to secondary users for maximizing throughput by...
Empty container repositioning, arousing coincidentally with the container shipping business, shows its significance nowadays in container control area, in which one of the key issues is the balance of container load and empty container transportation. In this paper, we first took a worldwide glance at current status of empty container repositioning. Then a general review on the past researches of...
