Abstract: a cooled axial flux electric motor includes a rotationally-fixed stator defining a rotational axis and having a plurality of conductive stator magnetic poles arranged radially about the axis. the motor also includes a rotor spaced axially from one side from the stator and rotatably mounted coaxially with the rotational axis and defined by inside and outside diameters. the rotor has a first exterior surface facing the stator and a second exterior surface arranged opposite the first exterior surface. a ferromagnetic rotor core defines the rotor second exterior surface. the rotor also includes alternating south and north pole permanent magnets (pms) arranged on the rotor core symmetrically around the axis and facing the stator. the rotor additionally includes channels extending radially outwardly across the rotor and configured to direct a coolant, via centrifugal force, from the inside diameter toward the outside diameter as the rotor rotates about the axis.

Abstract: a distributed computing system includes one or more computing devices and one or more communication links in electronic communication with one another. each communication link includes one or more nodes and a port switch. the one or more nodes are in electronic communication with one another by a communication link and the communication link is connected to the distributed computing system by the port switch. the port switch executes instructions to identify an online unique stream profile for a specific stream and determine an expected unique stream profile deviation during a specified interval of time. the port switch determines a difference between an offline unique stream profile and the online unique stream profile, compares an absolute value of the difference with the expected unique stream profile deviation, and in response to determining the difference is greater than the expected unique stream profile deviation, determines a fault has occurred.
