Abstract: Aerial vehicles are assigned to routes within a transportation network based on a state of charge, state of power, and/or state of health for the aerial vehicle. Such aspects can be modeled based on one or more statistical models and/or machine-learned models, among other examples. As another example, an energy budget is used to ensure that the state of charge, state of power, and/or state of health of the aerial vehicle during and/or after traveling the route remains within the energy budget. A payload is assigned to a route and an associated aerial vehicle, thereby generating an itinerary. In examples, the itinerary is validated by the aerial vehicle to ensure that the aerial vehicle is capable of traveling the route with the payload. In examples where the aerial vehicle rejects the itinerary, the itinerary is assigned to another aerial vehicle and a new itinerary is identified for the aerial vehicle.

Abstract: A solar receiver includes a hollow body, which has a longitudinal axis (8.4), a wall (8) surrounding the longitudinal axis (8.4), an opening (9) disposed in the wall (8) for the entry of heat rays, and an end region opposite the opening (9). The wall (8) includes an outer wall (8.1), an inner wall (8.2), and a partition wall (8.3) disposed therebetween. The outer wall (8.1) and the partition wall (8.3) enclose an outer annular space (8.1.1). The inner wall (8.2) and the partition wall (8.3) enclose an inner annular space (8.2.1). The outer annular space (8.1.1) has, in the end region, an inlet (12) for a free-flowing medium. The two annular spaces (8.1.1, 8.2.1) are conductively connected to one another in the region of the opening (9), and the inner annular space (8.2.1) has an outlet (11) for a free-flowing medium in the end region.

Abstract: An apparatus and a method for sorting, particularly chopped, aluminum scrap by alloy groups are disclosed, in which the aluminum scrap is separated into fractions, fractions of the aluminum scrap are irradiated by at least one neutron source, the gamma radiation that the individual fraction emits due to this neutron irradiation is detected by at least one detector, and based on this, an energy spectrum associated with the respective fraction is generated, based on which energy spectrum a relative ratio of the weight proportions of at least two alloy elements of this fraction is determined, and based on this relative ratio, this fraction is allocated to its corresponding alloy group, and then the fractions are sorted by the alloy groups to which they have been allocated.
