Seismic noise separation and attenuation is a fundamental topic in the seismic signal
processing and geological interpretation. Several kinds of algorithms are proposed for …

As magnetotelluric (MT) is an important method for exploring the geoelectrical structure of
the underground, it has motivated in-depth research and application by many geophysicists …

High-resolution seismic data allows us to better characterize the reservoir and detect the
hydrocarbon. To improve the resolution of seismic data, in this article, we extend the …

Studying the statistical characteristics of primary reflection coefficients is crucial for gaining a
deeper understanding of the structure of the Earth's rock layers. In this study, we collected …

Seismic high resolution processing plays a crucial role in seismic interpretation and
reservoir characterization. However, the low and high frequency of seismic signal are lost …

Flexible thin-walled elliptical bearing (FTEB) is a new type of bearing, and its elliptical inner
and outer rings make its vibration signal exhibit very unique characteristics, which are …

Singular value decomposition (SVD) plays a significant role in matrix analysis, and the
differential quotient difference with shifts (DQDS) algorithm is an important technique for …

The vibration signal associated with the operating process of circuit breakers (CBs) includes
a detailed operating status in the formation of the operating mechanism. To effectively …

In the process of seismic wave propagation, high-frequency energy is absorbed and
attenuated by the stratum, and the dominant frequency and resolution decrease. To recover …
