Design of an electronic image stabilization algorithm for flapping-wing flying robots

工程科学学报
During the flight of a flapping-wing flying robot, the unique flapping-wing propulsion mechanism causes periodic pitching and rolling motions of the body. In passing through different airspeeds and altitudes over different terrain, the wings cycle up-and-

Reconstructing Magnetotail Reconnection Events Using Data Mining is Feasible and Repeatable

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Recently, Stephens et al. (2023), https://doi.org/10.1029/2022ja031066 utilized a data mining (DM) algorithm, applied to 26 years of magnetospheric magnetometer observations coupled with a flexible formulation of the magnetospheric magnetic field, to reconstruct the global configuration of the magnetotail when the Magnetospheric MultiScale ...

Trajectory optimization of a flapping-wing robot in a wind field

工程科学学报
Owing to wave obstruction, the speed of the horizontal wind field decreases as it approaches the sea surface. Consequently, the wind field that increases with height is referred to as a gradient wind field.
