Intelligent vehicle scheduling in open-pit mines based on 5G antenna and improved Dijkstra algorithm
Gong-kuang zidonghuaComplex terrains such as deep pits and high slopes in open-pit mines cause physical signal blockage and multipath fading. Furthermore, existing path-planning algorithms tend to result in unstable vehicle trajectories or congestion due to local optima ...

Numerical investigations on the quasi-stationary response of antennas to wideband LFMCW excitation [PDF]
, 2014 In this contribution, we numerically investigate if the quasi-stationary (QS) response is a valid approximation for the response of antennas excited by wideband linear-frequency modulated continuous waveforms.
