A New Scheme for Residual CF4 Detection in Gas-Insulated

For the diagnosis of GIS, the decomposition gas species including CF 4 generated by partial discharges or breakdown are analyzed. Accumulation of the gas species indicates the history of the failure of GIS. However, most of the gas species are removed by an absorbent placed in a GIS vessel. The only CF 4 stays inGet price

A Neural Network Decomposition Algorithm for Mapping on

A decomposition of a graph G is a family of edge-disjoint subgraphs of G such that E G) = S F2FE(F . The subgraphs in decomposition can be decomposed further so decompositions can be hierarchical. A hierarchical decomposition of a graph G is represented by a tree Twhere a node s 2O(T) is associated with a subgraph Gs of G.Get price
