Gravity Terrain Effect of the Seafloor Topography in Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2007
Gravity terrain correction is used to compensate for the gravitational effects of the topography residual to the Bouguer plate. The seafloor topography off the eastern offshore of Taiwan is extremely rugged, and the depth of the sea bottom could be ...

A Residual Trend Surface Approach for Understory Terrain Correction to Estimate Forest Stand Heights Using Spaceborne Stereo Imagery and ICESat-2 Ground Photons

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Forest stand height is a key forest structural metric. Spaceborne stereo imagery can generate a spatially continuous digital surface model (DSM) over large areas; however, inaccurate understory terrain caused by canopy obstruction reduces the estimation ...

A Method for Traction Ability Research of a Rover Wheel on Mixed Planet Terrain with Movable Stones

Space: Science & Technology, 2023
The mixed terrains of terramechanics research are mainly composed of static stones and loose soil. The movement behavior of stones is often ignored while analyzing the influence of the wheel’s traction performance caused by mixed terrain. When a wheel is

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions

Advanced Materials, EarlyView.
Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

DC Flashover Dynamic Model of Post Insulator under Non-Uniform Pollution between Windward and Leeward Sides

Energies, 2019
Experience shows that under unidirectional wind or certain terrain, the surface of post insulators is non-uniformly polluted between windward and leeward sides, which affects the flashover characteristics.
