(2020) 27: 3544-3566 DOI: https://doi.org/10.1007/s11771-020-4509-5 Numerical simulation research on response characteristics of surrounding rock for deep super-large section chamber under dynamic and static combined loading condition FAN De-yuan(范德源)1, LIU Xue-sheng(刘学生)1, 2,......
methods are difficult to meet the requirements of the use conditions, and the abrasive flow precision machining technology can well complete the precision machining process of complex curved surfaces......
]. Traditionally, a complete trajectory from a start point to a target one can be solved using trajectory optimization-based methods. However, it is difficult to predict the driving environment due......
was excavated as a complete section during the simulation, and the distance in each step was 1 m [27]. There are six permutations of excavation sequences for the three tunnels in a triangular configuration......
the model predictive, part of the available training dataset is usually held out as a validation dataset when performing supervised machine learning. The complete processes of supervised machine learning......
base learners. κ=1 means that the classification results of two base learners are in complete agreement, indicating that the two base learners are identical. When κ=0, the two classifiers are agreed......
