Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Construction and Application of Online Vibration Frequency Response Analysis Method for Converter Transformer Winding

High Voltage, EarlyView.
ABSTRACT The harmonic current and vibration of a converter transformer are effective pieces of information for detecting mechanical faults in the winding. In this paper, the ratio of vibration acceleration to the current squared is defined as the vibration frequency response function (VFRF) of the winding, and then, a novel online vibration frequency ...

Dynamic Modal‐Based Vibration Characteristics Analysis and Looseness Fault Diagnosis in Transformer Winding

High Voltage, EarlyView.
ABSTRACT Limited by the theoretical basis and diagnostic methods, the winding mechanical condition monitoring often requires both normal condition vibration signals and present vibration signals, and the winding mechanical condition identification is completed by comparing with the normal condition signals.

Wind, waves, wing loading and the flight energetics of giant petrels

Functional Ecology, Volume 40, Issue 7, Page 1979-1993, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Wind is a major factor driving seabird movement and energetics, the effects of which are modulated by morphology. Developments in tagging technology now make it possible to test predictions from aerodynamic theory about the effects of wind on flight performance in free ...

Riding out the storm: Behavioural responses of a large herbivore to high‐Arctic winds

Journal of Animal Ecology, EarlyView.
Using 11 years of GPS data from 61 muskoxen in Northeast Greenland, we show how increasing wind speed and Arctic storms reshape movement modes and habitat selection. Muskoxen respond by bedding in dense vegetation, prioritizing energy conservation over foraging, revealing a simple behavioural strategy with potential fitness consequences under ...
