Frequency Dependent Microseisms Sources: A Case Study in Oregon
Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.Abstract The origin of microseisms—whether from deep‐ocean sources or coastal reflections—has been debated for decades. In this study, we use Distributed Acoustic Sensing (DAS) and Ocean Bottom Seismometer data collected offshore Oregon to investigate microseisms sources across a range of frequency bands. Our results reveal a clear frequency dependence:

Da saída: religião da saída da religião, arte da saída da arte
REVER - Revista de Estudos da Religião, 2018 Neste ensaio, procurarei compreender a recusa da sacralização da arte – e a negação do museu como lugar de culto dessa nova religião –, partindo de uma análise de um movimento religioso que se caracteriza por ter recusado o antigo sagrado e negado as formas elementares da religião arcaica: o cristianismo.

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.Abstract We proposed a method for estimating focal mechanisms based on S/P amplitude ratios from distributed acoustic sensing (DAS) records for single earthquakes and successfully obtained the mechanisms from four events. This method involves measuring the maximum amplitude ratio between the S‐ and P‐waves of the DAS records, followed by searching for ...

READ-BAD: A New Dataset and Evaluation Scheme for Baseline Detection in Archival Documents
, 2017 Text line detection is crucial for any application associated with Automatic Text Recognition or Keyword Spotting. Modern algorithms perform good on well-established datasets since they either comprise clean data or simple/homogeneous page layouts.

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 9, September 2024.Abstract Distributed acoustic sensing (DAS) has emerged as a promising seismic technology for monitoring microearthquakes (MEQs) with high spatial resolution. Efficient algorithms are needed for processing large DAS data volumes. This study introduces a deep learning (DL) model based on a Residual Convolutional Neural Network (ResNet) for detecting ...

Symbol detection in online handwritten graphics using Faster R-CNN
, 2017 Symbol detection techniques in online handwritten graphics (e.g. diagrams and mathematical expressions) consist of methods specifically designed for a single graphic type. In this work, we evaluate the Faster R-CNN object detection algorithm as a general

Geophysical Research Letters, Volume 51, Issue 11, 16 June 2024.Abstract Recent distributed acoustic sensing (DAS) experiments in ocean areas throughout the world have accumulated records for various wavefields. However, there are few tsunami records because tsunami observation depends on the DAS experimental period and its location.
