Time-optimal trajectories with bounded velocities and accelerations are known to be parabolic, i.e., piecewise constant in acceleration. An important characteristic of this class of trajectories is the distribution of the switch points, i.e., the time instants when the acceleration of any robot joint changes. When integrating parabolic trajectory generation into a motion planning pipeline, espe...

According to a widely accepted constraint on the content of intentions, here called the exclusivity constraint, one cannot intend to perform another agent’s action, even if one might be able to intend that she performs it. For example, while one can intend that one’s guest leaves before midnight, one cannot intend to perform her act of leaving. However, Deborah Tollefsen’s (2005) account of joi...

Background: Lower extremity injuries are frequently observed in car-to-pedestrian accidents and due to the bumper height of most cars, knee joint is one of the most damaged body parts in car-to-pedestrian collisions.Objective: The aim of this paper is first to provide an accurate Finite Element model of the knee joint and second to investigate lower limb impact biomechanics in car-to-pede...
