Automatic Horizon Picking Using Multiple Seismic Attributes and Markov Decision Process

open access: yesRemote Sensing, 2023
Picking the reflection horizon is an important step in velocity inversion and seismic interpretation. Manual picking is time-consuming and no longer suitable for current large-scale seismic data processing.

Seismic Phase Picking

open access: yes
Seismic phase picking, which aims to determine the arrival time of P- and S-waves according to seismic waveforms, is fundamental to earthquake monitoring. Generally, manual phase picking is trustworthy, but with the increasing number of worldwide stations and seismic monitors, it becomes more challenging for human to complete the task comprehensively ...

A Lindley-type equation arising from a carousel problem [PDF]

open access: yes, 2014
In this paper we consider a system with two carousels operated by one picker. The items to be picked are randomly located on the carousels and the pick times follow a phase-type distribution.

基于四川地震预警站网数据的震相检测模型迁移学习研究

open access: yesDizhen xuebao
2023年中国建成了全球规模最大的地震预警网,预警网中的台站配置了速度计、加速度计、简易烈度计(MEMS)等多种地震仪器。目前用于深度学习模型训练的数据集主要由速度计数据组成,不同类型仪器记录的数据在处理时精度会下降。为了解决这一问题,本文使用Yu等(2023)发布的BRNN模型作为预训练模型;然后使用2万6 739条人工标注的四川地区的速度计、加速度计和MEMS数据进行迁移学习。实验结果表明:迁移学习显著提升了模型对加速度计和MEMS预警仪器数据记录到的Pg,Sg震相的检测精度 ...
