Surface waveform modeling has played an important role on many continental-scale studies of upper mantle velocity structure, but it was seldom applied to the Chinese mainland study. The present study firstly analyzed surface waveform fittings for eight wave paths crossing through four different regions of the Chinese mainland (eastern, central, northern and western China), and then inverted for...

Abstract Knowledge of the composition Earth’s interior is highly relevant to many geophysical and geochemical problems. Neutrino oscillations are modified in a non-trivial way by matter effects can provide valuable unique information not only on density but also chemical isotopic deep regions planet. In this paper, we re-examine possibility performing an oscillation tomography Earth with atmosp...

Many geophysical problems involve inverting data in order to obtain meaningful descriptions of the Earth‘s interior. One of the basic characteristics of these inverse problems is their non-uniqueness. Since computation power has increased enormously in the last few years, it has become possible to deal with this non-uniqueness by generating and selecting a number of models that all fit the data...

free surface modeling plays an important role in some ocean structures design, especially in oscillating water column (owc) devices. boundary element method (bem) is a suitable method for free surface modeling due to its simplicity, quick solving, and low data storage requirement. in this paper, bem was used for free surface modeling in owc chamber and out of it. linear kinematic and dynamic bo...

The core mantle boundary (CMB) separates Earth's liquid iron outer core from the solid but slowly convecting mantle. The detailed structure and dynamics of the mantle within ~300 km of this interface remain enigmatic: it is a complex region, which exhibits thermal, compositional and phase-related heterogeneity, isolated pockets of partial melt and strong variations in seismic velocity and aniso...
