Animal-rights group sues over ‘disturbing’ work on sea lions
Conservation effort criticized for branding pups.
Conservation biology: Is this any way to save a species?
Thanks to the influence of a powerful US senator, more than $120 million has been pumped into research on Alaska's endangered Steller sea lions in just four years. Rex Dalton asks what we've learned.
State estimation for integrated vehicle dynamics control
This paper discusses a vehicle controller and a state estimator that was implemented and tested in a vehicle equipped with a combined braking and chassis control system to improve handling. The vehicle dynamics controller consists of a feed forward body roll compensation and a feedback stability controller. The estimator is based on a non-linear vehicle model combined with an extended Kalman filter. The Kalman filter is also connected to an algorithm, which estimates the tyre-road friction coefficient. The developed estimator was tested in a vehicle. Good results were achieved for normal and extreme driving manoeuvers.
