Collision-Avoidance Decision System for Inland Ships Based on Velocity Obstacle Algorithms
Journal of Marine Science and Engineering, 2022 Due to the complex hydrology and narrow channels of inland rivers, ship collision accidents occur frequently. The traditional collision-avoidance algorithms are often aimed at sea areas, and not often at inland rivers. To solve the problem of inland-ship

Ant navigation: resetting the path integrator [PDF]
Journal of Experimental Biology, 2006 SUMMARY Desert ants use path integration as their predominant system of long-distance navigation, but they also make use of route-defining and nest-defining visual landmarks. Such landmark-gained information might override the information provided by the path integrator, but nevertheless the path integrator keeps running.
