In this paper, we study path planning for first responders in the presence of uncertain moving obstacles. To support the path planning, in our research we use hazard simulation to provide the predicted information of moving obstacles. A major problem in using hazard simulation is that the simulation results may involve uncertainty due to model errors or noise in the real measurements. To address this...
To solve the serious wear problem of pantograph slide in electrified railway pantograph catenary system, lots of current-carrying wear experiments under different conditions were carried out with a self-developed sliding electrical contact testing machine. The experimental materials are immersed copper carbon slide and copper contact wire respectively. Relationships between wear rate of slide and...
It has to be aware that remote sensing images need to be encoded onboard using lossless compression method if all information of the image is required to be fully conserved for ground use. Also, to acquire as much onboard data as possible during one available pass of the satellite, it is necessary to consider efficiency of onboard data compression and transmission between satellite and ground segment...
