A method implemented at a management node comprises receiving measurement reports from the plurality of layers. The measurement report of each processing node comprises information about job(s) pulled from the upper layer if any and job(s) pulled by the under layer if any. The method further comprises determining information about failure in the cloud environment based on the measurement reports.

Abstract: Embodiments of the present disclosure relate to a method, a device, and a computer-readable storage medium for allocating system resources among a plurality of network slices in a communication network. In the communication network, a network device determines utility values of two network slices. A network slice corresponds to a set of network functions of a set of services served thereby. A utility value of the network slice indicates the level of demand for system resources by the set of services associated with the network slice. The network device determines a difference between the utility values of the two network slices. If the difference exceeds a threshold utility value, the network device re-allocates system resources among the plurality of network slices in the communication network.

Abstract: The present disclosure relates to a method for authenticating a user. The method comprises recording image data of the user and deriving at least one first facial feature of the user's face and at least one first gesture feature of one or more gestures of the user from the image data. The method further provides for determining a degree of access of the user to data depending on whether the first gesture feature corresponds to at least one predetermined second gesture feature and whether the first facial feature corresponds to at least one predetermined second facial feature.

Abstract: A method for transporting a rescue device from an aerial vehicle to a person to be rescued is provided. The rescue device is attached to the aerial vehicle. The method includes launching an unmanned aerial vehicle from the aerial vehicle. An end portion of the rescue device is attached to the unmanned aerial vehicle via a first connection and a second connection. The end portion of the rescue device is releasable by the person to be rescued from the first connection for handover. The method further includes approaching the person to be rescued by the unmanned aerial vehicle in order to enable the person to be rescued to reach the end portion of the rescue device. Additionally, the method includes determining at the unmanned aerial vehicle whether the end portion of the rescue device is released from the first connection.
