Finding the key nodes of the network is one of the most important applications in Community Detection. This paper combined Centrality, Cluster Coefficient and PageRank ideas, establish the measurement system of key nodes and according to the Kendal correlation coefficient of each index to modify the measurement system. Finally, using the Fagin algorithm to carry on the key nodes of the multidimensional...
Time-variant is the typical characteristic of components and systems and the classical approach for time-variant reliability analysis relies on the computation of up-crossing rates. In order to get the up-crossing rate, the common up-crossing approach uses a FORM method to compute the instantaneous reliability index at each time. FORM method likely lead to decrease of the result's accuracy when the...
The objective of this study was to introduce a new high-performance diameter distribution function. The long-term repeated measurement data sets, consisted of 150 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata) plantations in the southern China, were used. R distribution had presented a more accurate simulation than three-parametric Weibull function. The parameters p, q...
A vehicle simulation model for Dual Clutch Transmission (DCT) is designed in Matlab/Simulink, and more importantly, an objective description of the method to evaluate its shift quality based on neural network (NN) is implemented. The objective evaluation method adopted the theory of NN prediction; NN is trained and tested with sample vectors comprised by shift quality evaluation index, subjective...
An automatic tracker is developed, which is capable of tracking intra-cellular features in living cells from 3-D confocal image sequences corrupted by noise. The proposed approach takes a Poisson MAP-MRF classification as an initial stage to detect objects. These are then used to update the multiple target locations generated by 3D Poisson Kalman Particle filters (PKPF). A probabilistic nearest neighbour...
