Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain
Wildlife Biology, EarlyView.Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Autonomy for Unmanned Surface Vehicle
, 2018 Autonomous navigation has been successfully presented and developed both on ground and air. Though, autonomy on maritime surface vehicles has proven to be more challenging. In order to have an Autonomous Surface Vehicle (ASV), it ought to have a completely functional Guidance, Navigation and Control (GNC) system.This work presents part of the GNC ...

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.
