Trajectory Generation using Sharpness Continuous Dubins-like Paths with Applications in Control of Heavy Duty Vehicles [article]

Rui Oliveira, Jonas Mårtensson School of Electrical Engineering, ACCESS Linnaeus Centre, KTH Royal Institute of Technology Scania, Autonomous Transport Solutions)
2018 arXiv   pre-print
We present a trajectory generation framework for control of wheeled vehicles under steering actuator constraints. The motivation is smooth autonomous driving of heavy vehicles.  ...  We propose the new concept of Sharpness Continuous curves, which uses cubic and sigmoid curvature trajectories together with circular arcs to steer the vehicle.  ...  The generated paths/trajectories are used as a reference signal for the controllers implemented in the vehicle.  ...

Performance Improvement by Introducing Mobility in Wireless Communication Networks [article]

Hailong Huang
2017 arXiv   pre-print
Introducing mobility is to let the base stations fly in the sky, resulting in less investment. We consider one of the key issues of using drones to serve cellular users: drone deployment.  ...  We study the influence of mobility in these networks. In wireless sensor networks, we consider the usage of mobile sinks to collect sensory data from static nodes.  ...  As a variant of DTSP, TSP for Dubins vehicles with neighbourhoods (DTSPN) has been studied.  ...
