The acquisition, management and analysis of mineral resources with both simplicity and efficiency are critical problems we are now confronted with. This paper discusses the related conceptions and technologies about GIS and how to apply it to the field of mineral exploration with its advantages. Later this paper promotes itself with a case of Lao Zhai-wan(More)
An improved genetic algorithm(GA) named MST-GA is proposed to minimize amount of PMUs for fully observing huge scale power grid. It adopts minimum spanning tree algorithm to repair unfeasible solutions, and makes use of the topology of power grid in the process of mutation. The simulation results of IEEE30 and IEEE39-bus system show that the algorithm can(More)
