We propose real-time traffic state estimation using a state-space model that takes account of variability in the fundamental diagram (FD) and sensing data. In free flow situations, for instance, the FD regulating driving behavior may vary among drivers w...

Fluid resonance may occur in a narrow gap between two side-by-side vessels under wave actions, which can cause significant wave height amplification inside the gap and further induce large wave loads and motion responses of the vessel. Based on an open-s...
