Dijkstra algorithm is a classic algorithm of computing the shortest path between two points. In past the amount of urban vehicles is small, so the shortest path is the optimal one. However, with the increasing of cars, traffic congestion is serious. The path calculated by using traditional Dijkstra is still the shortest path, but it is not necessarily the optimal. Therefore, in order to solve the...
To ensure autonomous underground mining vehicles moving smoothly underground, path generation and navigation for vehicles are essential. This paper comes up with a method to generate trajectory and navigate the vehicles with laser beams. To give vehicles planned path, a map of the working area is needed. With the assistance of an offline path planning software, operators can make or modify the path...
The nature of education is to serve the community. MBA education is to develop elites who are capable to serve the nations. This paper concentrates on analyzing the problems arising from MBA education. The essence of MBA education has decided the targets of MBA education. MBA teaching model is designed to achieve these targets. Thus, the MBA course setting is affected by both teaching methods and...
Real-time video monitoring is necessary for remote control mining while real-time positioning of underground equipments is also necessary for unmanned mining. In this paper, a new pattern combining WLAN with ZigBee is proposed to solute the two problems above. In the pattern, RSSI(Received Signal Strength Indication) values of ZigBee anchor nodes are used to calculate the position and posture of underground...
