, by using the Monte-Carlo technique, random joint network was generated in the domain of interest. Based on the joint network, the triangular DDA block system was automatically generated by adopting... examples were carried out to obtain some insight into the failure behavior of rock mass containing random joints. From the numerical results, it can be found that the crack initiates from the crack tip......
Nature 2018 Abstract: To screen genetic polymorphisms of Panax ginseng, as well as those of Panax quinquefolium and Panax notoginseng, analysis of random amplified polymorphic DNA (RAPD) was performed using 120 random primers. Of the successful amplicons obtained, the Panax ginseng-specific RAPD marker C-12 was cloned into a TA vector and sequenced (GenBank access number KU553472). Based......
of suspension bridges under random traffic flow based on the first-passage criterion XIAO Xinhui1, 2, 3, LU Naiwei1, LIU Yang1, GUO Xin3 (1. School of Civil Engineering and Architecture... girders under random traffic flow. The boundary cross rates of dynamic responses are stable with the increase of random vehicle sample number. In 100 years, the dynamic reliability index will drop......

to guarantee that the neighbors have a high real time ability, the random walk process was utilized to update the list of neighbors periodically by using Monte Carlo methods. In addition, transition probability matrix was calculated by the Metropolis- Hastings methods to satisfy the expected stationary distribution of random walk. The results show that the proposed algorithm can select excellent peers......
