structure. More specifically, XGBoost enumerates all the possible tree structures q. The greedy algorithm starts from a single leaf and iteratively adds branches to the tree. Assume that IL and IR......
with the stress state and grain structure. Thus, the corresponding short-term and long-term micro-parameters calibrated by uniaxial compression and creep test can be directly used in the triaxial creep......
the Wufeng and Longmaxi formations in Southeast Sichuan basin[J]. Oil & Gas Geology, 2015, 36(6): 1001-1008. [26] YANG Feng, NING Zhengfu, WANG Qing, et al. Pore structure characteristics of lower......
;Metallurgical structure of beryllium copper plate produced by HCCM horizontal continuous casting with various casting speeds 由图7可以看出,当拉坯速度为25 mm/min时,合金中的柱状晶粗大且晶界较平直,柱状晶平均宽度为1200 μm,柱状晶生长方向与连铸方向的夹角为0°~10......
rate was 1 s-1, the large deformation strain rate contributed to forming a large number of dislocations and structure defects, and large deformation storage energy could increase the nucleation rate......
with their microhardness measurements for a holistic understanding of structure-property relationships of the local weld sub-regions. The findings were effectively correlated to achieve an insight... between their physical and mechanical properties. Despite the same crystal structure (FCC) of Cu and SS, the other contrasting properties especially their melting point and thermal conductivity......
on wetland soil microbial biomass and bacterial community structure[J]. Science of the Total Environment, 2016, 557/558: 785-790. [4] LIANG Jie, LIU Jia-yu, YUAN Xing-zhong, ZENG Guang-ming, YUAN Yu-jie......
to complete all analyses of the surface structure sample. This is a general issue while processing the images that have higher resolutions such as 5MPx or more. In the paper, the method for improving......
].Physics Letters A, 2007, 368(6): 450-457. [29] AKBARI M R, GANJI D D, NIMAFAR M, AHMADI A R. Significant progress in solution of nonlinear equations at displacement of structure and heat transfer......
, and they are used widely in different industries namely the transportation and aero-space [1-3]. However, their poor ductility because of the hexagonal closed-pack (HCP) crystal structure causes a distinct......
