Optimization of seismometer arrays for the cancellation of Newtonian noise from seismic body waves [PDF]

Classical and quantum gravity, 2019
Newtonian noise (NN) from seismic fields is predicted to become a sensitivity limiting noise contribution of the gravitational-wave detectors Advanced LIGO and Virgo in the next few years.

Large Dynamic Range and High Sensitivity PGC Demodulation Technique for Tri-Component Fiber Optic Seismometer

IEEE Access, 2020
Three-component fiber optic seismometers are widely used in the detection of seismic signals. The arctangent approach of phase-generated carrier (PGC-Arctan) demodulation algorithm is one of the commonly used demodulation techniques in FOISs.

Seismic Observation and Analysis Based on Three-Component Fiber Optic Seismometer

IEEE Access, 2020
We demonstrate a three-component fiber optic seismometer for seismic observation, with no electronics in the sensor probe, but relying exclusively on optical fiber in the form of an unbalanced Michelson interferometer, with state-of-the-art performance ...

Implications of Dedicated Seismometer Measurements on Newtonian-Noise Cancellation for Advanced LIGO. [PDF]

Physical Review Letters, 2018
Newtonian gravitational noise from seismic fields will become a limiting noise source at low frequency for second-generation, gravitational-wave detectors. It is planned to use seismic sensors surrounding the detectors' test masses to coherently subtract

Wireless seismometer for venus [PDF]

2014 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNet), 2014
Measuring the seismic activity of Venus is critical to understanding its composition and interior dynamics. Because Venus has an average surface temperature of 462 °C and the challenge of providing cooling to multiple seismometers, a high temperature, wireless sensor using a wide bandgap semiconductor is an attractive option.

A Multimodal Interactive Framework for Science Assessment in the Era of Generative Artificial Intelligence

Journal of Research in Science Teaching, EarlyView.
ABSTRACT The rapid evolution of generative artificial intelligence (GenAI) is transforming science education by facilitating innovative pedagogical paradigms while raising substantial concerns about scholarly integrity. One particularly pressing issue is the growing risk of student use of GenAI tools to outsource assessment tasks, potentially ...

Subtle relict channels associated with large dolines in an area formerly beneath the Laurentide Ice Sheet, northern Ohio, USA

Boreas, EarlyView.
Low‐relief dry channels appear out of place across a glaciated karst landscape in northern Ohio. Channels are only a few metres deep cut into limestone and draped with a veneer of till. Several hypotheses are proposed for explaining the channels. Low‐relief dry channels are observed across the Bellevue‐Castalia Karst Plain of north‐central Ohio, USA ...

Virtual sensing of seismic floor responses for rapid prioritization of critical equipment inspection in nuclear power plants

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Critical equipment in nuclear power plant auxiliary buildings such as control cabinets, panels, transformers, and diesel generators often malfunction before structural damage occurs, demanding rapid post‐earthquake inspection prioritization.
