Seasonal variations and challenges in estimating populations and identifying species of Korean ungulates using drone‐derived thermal orthomosaic maps

Wildlife Biology, EarlyView.
Drones equipped with thermal infrared (TIR) cameras offer significant time and labor savings in estimating wild ungulate populations. However, accurately monitoring forest‐dwelling ungulates remains challenging due to their elusive behavior and complex habitat.

Modelling the Four‐Dimensional Power Line Sag Dynamics by Point Signature in Time‐Series Synthetic‐Aperture Radar Images

High Voltage, EarlyView.
ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

Mechanism of Quasi‐Power‐Frequency Resonant Overvoltage Triggered by Multiple Lightning Strikes in High‐Voltage Alternating Current Systems Equipped With Shunt Reactor

High Voltage, EarlyView.
ABSTRACT This paper investigates the generation mechanism of quasi‐power‐frequency resonant overvoltage triggered by multiple lightning strikes in high‐voltage alternating current (HVAC) systems equipped with shunt reactors. Based on field measurements from a 500 kV AC system, equivalent and simplified circuit models have been established to analyse ...
