Abstract: A hydraulic circuit, in particular to a hydraulic steering circuit for steering at least one vehicle axle, the hydraulic circuit including a first fluid path having a first end and a second end and providing fluid communication or selective fluid communication between the first end and the second end of the first fluid path; and a second fluid path providing fluid communication or selective fluid communication between the first end of the first fluid path and the second end (2) of the first fluid path, in parallel to the first fluid path or to a section thereof. In some aspects, the first fluid path includes a first hydraulic displacement unit; and the second fluid path includes at least a first proportional bypass control valve for controlling a bypass fluid flow in the second fluid path. The hydraulic steering circuit may be part of a driveline for a vehicle.

Abstract: A system for evaluating performance of a network providing communication services by means of a generalized processor sharing packet scheduling discipline. The services may include classes of services having real time and non real time (i.e. “elastic”) requirements, respectively, and the classes of services have relative priorities. The system includes a performance evaluation module configured for evaluating performance of a given class of services as a function of the load produced by other classes of services having a priority higher than or equal to the given class as well as of perturbation effect exerted on the given class by other classes having priority higher than the given class, and a computation module configured for determining the load and the perturbation effect as weighed sums of the contributions of each of the other classes to the load and the perturbation effect.
