Foundation pit engineering is composed of some inter-related and relatively independent sub-engineering which makes it possible to introduce the distributed parallel optimal method into foundation pit engineering design. Based on the genetic algorithm with intrinsic parallelism, a distributed three-level co-evolution model and its corresponding algorithm, which can realize collaborative optimal design...
To promote the application of web-based expert system, the significance of the construction of the web-based expert system was introduced, the principles and methods were explained, and the latent problem was discussed, the tendency was also analyzed.
Based on probability, the paper recommends a new inference method for validating the trusted forensics. Using graph theory, the original data is formalized to abstract data, and is shown as some nodes in the graph. The operation actions and the forensics methods are abstracted to the edge sets. With these, and using probability theory, the probability of each node is calculated as its credence. With...
Crossed cube is a variation of hypercube, but some properties of the former are superior to those of the latter. However, it is difficult to extend the scale of crossed cube networks. For example, it is necessary to double the number of nodes to extend the scale of crossed cube networks. As a kind of hierarchical ring interconnection networks HRN, crossed cube-connected ring interconnection network...
Information entropy is an effective description for the uncertainty of a system, and could be used for the symptom to detect the vibration changes of steam turbine. Based on the faulty signals collected from rotor test rig, three information entropy: singular spectrum entropy, power spectrum entropy, wavelet energy spectrum entropy were calculated as information entropy data. Probability neural networks(PNNs)...
