We have evaluated arrival-time picking algorithms for downhole microseismic data. The
picking algorithms that we considered may be classified as window-based single-level …

Underground target detection plays an important role in maintaining underground space
security and relies on efficient real-time detection methods. Electromagnetic detection …

通过对合成微震数据和实测微震记录的处理实验, 对自动检测有效微震信号的STA/LTA
(短时窗平均/长时窗平均) 算法及其改进的加权系数法, 多窗口算法和修正的能量比算法进行了 …

从地震波形数据中快速准确地提取各个震相的到时是地震学中的基础问题.
本文针对上述问题提出了利用深度神经网络拾取到时的新方法, 建立了用于地震到时提取的17 …

We have developed three methods for the automatic picking of first breaks that can be used
for marine, dynamite, or vibroseis shot records: a modified Coppens's method, an entropy …

Acoustic emission (AE) technique, as an effective method to monitor the crack
characterization in concrete materials is investigated in this paper. An improved approach …

In exploration geophysics, the first arrivals on data acquired under complicated near-surface
conditions are often characterized by significant static corrections, weak energy, low signal …

The acoustic emission (AE) technique is one of the most widely used in the field of structural
monitoring. Its popularity mainly stems from the fact that it belongs to the category of non …

Arrival time picking is a critical step in the analysis of geophysical data. This study aims at
improving the standard short-term-average/long-term-average (STA/LTA) method using soft …

Objective and motivation Time-of-flight (TOF) tomography used by a clinical ultrasound
tomography device can efficiently and reliably produce sound–speed images of the breast …
