The spatial and temporal distributions of acoustic emission (AE) during the deformation of samples containing an inhomogeneous fault have been studied under biaxial compression. The results show that
The principles and applications of laser real-time holographic interferometry (LRTHI) and radar differential inter-ferometry (RDI) technologies are described in this paper, respectively. By using LRTH
Argo floats are free-moving floats that report vertical profiles of salinity, temperature and pressure at regular time intervals. These floats give good measurements of temperature and pressure, but s
The use of a priori knowledge in remote sensing inversion has great implications for ensuring the stability of inversion process and reducing uncertainties in retrieved results, especially under the c
Euler Number is one of the most important characteristics in topology. In two- dimension digital images, the Euler characteristic is locally computable. The form of Euler Number formula is different u
After processing 204 data of historical earthquakes for M≥4.5 from 1900 to 1996 in the area centered at Beijing (39.9°N, 116.4° E; ±3°), two correlations have been suggested: One is between earthquake
