Abstract: Although most of the planetary boundary layer (PBL) parameterizations have demonstrated the capability to reproduce many meteorological phenomena in the lowest few kilometers, little attention has been paid to the prediction ...

Abstract: In this paper, the design and implementation of a novel leg–wheel robot called Transleg are presented. Transleg adopts the wire as the transmission mechanism to simplify the structure and reduce the weight. To the best ...

Abstract: This paper presents a theoretical investigation on excess sludge production in membrane bioreactors for municipal wastewater treatment. Based on mass balances of sludge and substrate, a formula to predict the excess sludge ...

Abstract: In this paper, forced convection heat transfer occurring in microchannels with different microstructures is investigated numerically. It is found that vortices will appear in the microstructure ...

Abstract: Load testing is usually used to evaluate the load-carrying capacity of long-span bridges in their service life. However, a large number of calibration trucks should be arranged in complicated loading patterns to deform ...

Abstract: The rapid proliferation of tunnel construction presents challenges to the safe operation of tunnels. Although Structural Health Monitoring Systems (SHMSs) have been widely used to prevent tunnel disasters, it is still ...

Abstract: In this paper, a novel transformable leg-wheel mechanism is proposed. It has three active joints, among which the hip roll joint is directly driven, the hip pitch joint is driven by gear transmission, and the knee joint ...
