The economic and economic-statistical designs of an X¯ control chart for two-identical unit series systems with condition-based maintenance is studied in this paper. This system is described using a five-state continuous time Markov chain. We assume that the system is monitored by an X¯...

In this paper, an M–EEMD–ELM model (modified ensemble empirical mode decomposition (EEMD)-based extreme learning machine (ELM) ensemble learning paradigm) is proposed for landslide displacement prediction. The nonlinear original surface displacement deformation monitoring time series of...
