Abstract: A method for predicting the behavior of at least one road user in a traffic situation. The method includes: obtaining a graph representation of the traffic situation, wherein nodes represent road users, edges represent interactions between the road users and define an adjacency between road users, each node is associated with a state, and each edge is associated with edge attributes; computing an evolution of the states of the nodes based at least in part on a self-evolution of the state of each considered node that is dependent on this state and mediated by a self-evolution operator; and an interaction of each considered node with other nodes that is dependent on the states of these other nodes and mediated by an interaction operator; and computing a sought property that characterizes the behavior of the at least one road user.

Abstract: A method of winding a stator of a polyphase brushless DC motor, the stator including uniformly spaced stator teeth which project inwardly from a stator core and leave a cylindrical inner region exposed. The teeth are wound in pairs with a winding wire to form a winding pair, the winding of each winding pair being performed by, starting from a wire beginning of a winding wire, winding a first stator tooth in a first direction, guiding the winding wire to a second stator tooth which immediately follows the first stator tooth in a first circumferential direction, and winding the second stator tooth in a second direction opposite to the first direction. The winding pairs are structured to be supplied with current so that a north pole and a south pole are opposite each other in the stator in the circumferential direction.
