Stochastic modelling of the pulse-like near-fault ground motions with time-frequency representation
Seismic near-fault ground motions differ from those in the far-field. They could contain large amplitude and long period velocity pulses and cause damage to structures. In the present study, we propose a new s...

Open AccessAn algorithm to simulate nonstationary and non-Gaussian stochastic processes
We proposed a new iterative power and amplitude correction (IPAC) algorithm to simulate nonstationary and non-Gaussian processes. The proposed algorithm is rooted in the concept of defining the stochastic proc...

Damage zones induced by in situ stress unloading during excavation of diversion tunnels for the **** II hydropower project
During the excavation of deep tunnels with high in situ stress, the stress unloading path caused by the rock mass excavation has important influences on the formation of the EDZ (excavation damage zone). In th...

Observational Results of the ChangE-1 Solar X-Ray Monitor
We present the primary observations of the Solar X-ray Monitor (SXM) payload onboard the ChangE-1 lunar exploration satellite, which was launched on 24 October 2007. The SXM payload uses a solid-state silicon P-I...

Shape-driving effect of the proton 1/2[541] band in 171Ta
High-spin states in 171Ta were populated through the heavy-ion fusion-evaporation reaction 157Gd (19F, 5n)171Ta at 105MeV beam energy. Lifetimes of the levels of the πh 9/21/2[541] band ha...
