1. Dynamic motion planner with trajectory optimisation for automated highway lane‐changing driving.

Author

Liu, Xiao, Liang, Jun, and Zhang, Hua

Abstract

This study proposes a dynamic motion planner with trajectory optimisation for automated highway lane‐changing driving. Owing to the connected and automated vehicles (CAVs) technology that the real‐time traffic information can be obtained, alternative trajectories can be generated to satisfy the vehicle kinematic constraints and avoid many types of potential collisions. An optimal control theory is adopted to select an optimal lane‐changing path from the finite path set, and the appropriate acceleration and speed for the execution path are also determined. In order to avoid unnecessary motion re‐planning process, this study puts forward a collision‐avoidance monitoring algorithm to reduce the time consumption costs of the motion planner. Moreover, an online planning framework based on 'decision‐execution' is explored. Applying this timeline framework can not only help to evaluate the dynamic planner's online performance, but also reduce the deviation between the online calculation and the actual execution caused by the time consumption. The simulations are performed in PreScan‐Simulink platform and the experimental results show that the presented dynamic planner can complete the lane‐changing manoeuvre safely and effectively in a high‐speed environment.

9. Cerenkov radiation: time dependent B field over a finite path

Author

Neighbors, John R., Buskirk, Fred R., Naval Postgraduate School (U.S.), Physics, Lyman, Kathleen M., Neighbors, John R., Buskirk, Fred R., Naval Postgraduate School (U.S.), Physics, and Lyman, Kathleen M.

Abstract

This preliminary study investigated the magnetic field radiated from a passing charge bunch traveling over a finite path. Beginning with the infinite path case for a ramp front charge distribution, limits were derived to solve for the magnetic radiation field over a finite path. Radiation pulses were computed and graphed for many different positions of an observer with respect to the beam line. Comparisons of results show that the similarity in pulse shapes does not depend exclusively on the observer's position with respect to the Cerenkov region, but also on certain time conditions in each case., http://archive.org/details/cerenkovradiatio1094521705, Lieutenant Commander, United States Navy, Approved for public release; distribution is unlimited.
