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.

Developing Implantable High‐Sensitivity Piezoelectric Thin‐Film Sensor to Monitor Partial Discharge of Generator Stator Windings

High Voltage, EarlyView.
ABSTRACT Insulation failures resulting from partial discharges (PD) in generator stator windings represent a leading cause of generator breakdowns. Conventional acoustic emission sensors for detecting PD ultrasonic signals are typically made from bulky piezoelectric materials and are restricted to external placement on the generator.

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 ...

(Dis)trust in Digital Insurance: How Datafied Practices Shift Uncertainties and Reconfigure Trust Relations

The British Journal of Sociology, EarlyView.
ABSTRACT Trust is both a prerequisite and a product of insurance, as insurance contracts are built on and create trust relations that enable a risk‐averse perspective towards the future. At the same time, insurer‐policyholder relationships are characterised by a persistent distrust, rooted in insurance economics and industry reputation. In this article,

A Novel Multidisciplinary Approach for Reptile Movement and Behavior Analysis

Integrative Zoology, EarlyView.
We present a novel multidisciplinary approach capable of advancing research on reptiles’ behavior. Our approach uses integrated tools and methods for the digitization, reconstruction, and visualization of reptiles and their behavior. We (i) record movement through tri‐axial accelerometers, video cameras, and motion capture systems; (ii) ground‐truth ...
