Unmanned Surface Vehicles (USV) with capabilities of mobile sensing, data processing, and wireless communication have been deployed to support remote aquatic environmental monitoring. This paper introduces a sampling planner for spatiotemporal survey of an aquatic environment using a USV-based sensing system. The sampling planner is proposed to distribute the Sampling Locations of Interest (SLoIs)...
The solidification behavior of Sn-3.0Ag-0.5Cu solders and Sn-3.0Ag-0.5Cu/Cu joints was investigated by using differential scanning calorimetry (DSC) incorporated into the reflow process. The critical factors influencing the undercooling behavior of the solders and joints, such as the solder size, composition and substrate size, were examined. The results show that the type of the primary solidification...
As an innovative product in foreign financial market, weather derivatives provide new ways for risk managing and transference. Its pricing is a core problem in researches. This paper applies the Ornstein-Uhlenbeck model, combining by time series assumption to simulate the variance of weather process, estimates the parameters using Shanghai's temperature data of years 1951–2009. Then the accuracy of...
