Experimental assessment of large mammal population estimates from airborne thermal videography

Wildlife Biology, EarlyView.
Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.

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.

Research on the Audible Noise Spectrum Characteristics of Typical AC Bundled Conductors in High‐Altitude Areas at 4300 m

High Voltage, EarlyView.
ABSTRACT The low pressure in high‐altitude areas exacerbates the issue of audible noise (AN) caused by intense corona discharge on the conductor surface. This problem is a critical factor in the structural design and conductor selection for extra‐high‐voltage and ultrahigh‐voltage (UHV) AC transmission lines.

Wave‐Velocity‐Based Temperature Monitoring Applied to Underground Power Cables in Medium‐Voltage Networks—Discrimination of Individual Cable Temperatures in a Distribution Grid

High Voltage, EarlyView.
ABSTRACT The thermal state of underground power cables can be monitored based on the temperature dependency of the dielectric permittivity of the insulation material. The resulting temperature‐dependent wave velocity is used as a thermometric property. To this end, the signal propagation time along a cable of an injected signal is determined.

Financial Literacy Intervention and the Willingness to Pay for Digital Credits: A Scalable Video‐Based Approach in Kenya

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Rapid growth in digital finance has expanded credit access for rural smallholders, yet financial capability has not kept pace with access. Where fee structures are opaque and search is costly, this gap raises the risk of expensive borrowing in digital financial services.
