A multiobjective, reliability-based design optimization (RBDO) is performed considering manufacturing uncertainties in order to facilitate the performance and reliability of a centrifugal compressor. During the RBDO procedure, Monte Carlo Simulation (MCS) is utilized to calculate failure probability. Latin hypercube design (LHD) is adopted to sample and form simulation experiment scheme. Besides,...
In order to improve the remove-restore theory, a novel algorithm based on wavelet analysis has been proposed in this paper. Through the similarity comparison between earth gravity field model and terrain correction, it is found that the model gravity anomalies contain some of high-frequency signals caused by terrain. Given this, the wavelet analysis theory has been introduced here to extract high-frequency...
There are two method frequently used for parallelization: data parallel and task parallel. According to the characteristics of analysis of digital terrain, data parallel is more applied, so Petri nets is introduced in this paper to describe the parallel relationships within data patitions based on granularity model. As for different storage environment, corresponding scheduling algorithms are proposed...
