Quantitative prediction of concealed mineralization is always confronted with difficulties in comprehensive analysis between 2D and 3D data and between qualitative and quantitative data. A weighted shortest-distance field method is proposed here to track, in 3D heterogeneous space, the shortest migration paths of ore-forming elements from an orebody to the ground surface, assuming that ore-forming...
This paper proposes a virtual hierarchical mesh network and efficient subnet agent selection method to reduce the routing table size of servers in server-only data center networks for better scalability of the network.
Mixel decomposition of remote sensing images is one of valid assistance means for improving quality of feature extraction from the images. Some problems exist in normal linear mixels decomposition, for example, registration error is too large, and neighbourhood information can be took full advantage of and so on. These result in that distortion of new images generated after linear mixels decomposition...
Natural properties of stochastic searching strategies and operations in metaheuristic algorithms have important influence on convergence performance of various metaheuristic algorithms. Through similarity analysis to two kinds of metaheuristic algorithms, exact heuristic algorithm based on branch-and-cut is put forward according to change trend of similarity between two arbitrary high-quality solutions...
