虽然本文方法重建的地震数据信噪比要比压缩感知技术常用的稀疏基高, 但还不能令人完全满意, 因此, 我们下一步的研究方向是构造重建效果更好的稀疏基。 1 基本原理 2 合成数据测试及分析 3 实际地震数据重建及分析 4 结束语 Funding 国家自然科学基金项目(41304086) the Natural Science Foundation of China(41304086...
The code requirements for preventing the panel zone yielding and for the strong-column weak-beam design have also been applied. Drift checks have been performed based on the code limits. ECP-201 specifies that the computed displacement from the reduced lateral forces is amplified by a factor ...
4). The distribution of seismicity determined by local networks also shows a 15° dip in the seismically active zone [10]. Time migration of the refracted waves provides an image of the interface beneath the Derveni array. It shows an undulation that reflects the block structure across the ...
This is in agreement with the spread of aftershocks near the rupture zone due to the stress redistribution after the mainshock. The eigenvalue variance and first eigenvalue features (Figures 3c and 3d) indicate that the fault is most active during the aftershock periods. In addition, the eigen...
