Physically consistent mesoscale model evaluation in complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study introduces a novel approach for evaluating mesoscale atmospheric models in complex terrain by selecting physically consistent grid points and applying height‐based corrections. The method corrects for sensor height and terrain elevation differences between model and observations using a time‐varying lapse rate.

Friction Shock Absorbers and Reverse Thrust for Fast Multirotor Landing on High‐Speed Vehicles

Journal of Field Robotics, EarlyView.
ABSTRACT Typical landing gears of small uninhabited aerial vehicles (UAV) limit their capability to land on vehicles moving at more than 20–50 km/h due to high drag forces, high pitch angles and potentially high relative horizontal velocities. To enable landing at higher speeds, a combination of lightweight friction shock absorbers and reverse thrust ...

Liquid‐Solid Triboelectric Nanogenerators in Physical and Chemical Sensors‐A Review

Small, EarlyView.
Liquid‐solid triboelectric nanogenerators (L‐S TENGs) have emerged as promising self‐powered sensors that convert liquid–solid interactions into electricity. This review highlights their working principles, recent applications in physical and chemical sensing, and performance improvements.
