I propose to identify an SVAR, up to shock ordering, using the autocovariance structure of
the squared innovations implied by an arbitrary stochastic process for the shock variances …

Third generation and future upgrades of current gravitational-wave detectors will present
exquisite sensitivities which will allow to detect a plethora of gravitational wave signals …

Seismic waveform data are generally contaminated by noise from various sources.
Suppressing this noise effectively so that the remaining signal of interest can be successfully …

We introduce a novel multichannel blind deconvolution (BD) method that extracts sparse
and front-loaded impulse responses from the channel outputs, ie, their convolutions with a …

钻头随钻地震技术是利用钻井过程中钻头冲击地层产生的振动作为震源的井中勘探技术.
它凭借不中断钻井作业这一特点, 可以实现连续的逆垂直地震剖面(Reverse Vertical Seismic …

Seismic waveform data recorded at stations can be thought of as a superposition of the
signal from a source of interest and noise from other sources. Frequency-based filtering …

Abstract The Drill Bit Seismic While Drilling (DB-SWD) is an in-well exploration technology
that uses the vibration generated by the drill bit as seismic source during the operations …

We detail a novel multichannel blind deconvolution (BD) algorithm that extracts the cross-
correlated or interferometric Green's functions from the records due to a single noisy source …

Understanding the subsurface complexity is critical for a successful drilling campaign. This
task requires stretching and integrating our data to the resolution limits to map the regional …

Diffractions provide valuable information about the local discontinuities in the subsurface.
Proper imaging of diffractions can provide a valuable subsurface attribute that complements …
