Collision Avoidance Method for Autonomous Ships Based on Modified Velocity Obstacle and Collision Risk Index

open access: yesJournal of Advanced Transportation, 2022
A novel real-time collision avoidance method for autonomous ships based on modified velocity obstacle (VO) algorithm and grey cloud model is proposed. A typical VO algorithm is used to judge whether there is a collision risk for ships in the potential ...

SMASH navigators [PDF]

open access: yesMagnetic Resonance in Medicine, 2003
AbstractThe additional data acquired when using multiple receiver coils is commonly used to improve SNR or reduce acquisition times. It may also be used to remove image artifacts by selectively replacing corrupt data. In the present study, a correction scheme is presented based on simultaneous acquisition of spatial harmonics (SMASH) that enables ...
