Abstract: Techniques for granting, for a device, access to additional functionality requested by user inputs received by the device are described. A system may receive, from a device, a first user input requesting content of a content type requiring additional functionality access in order for the content to be sent to the device. The system may exchange data with an access control system in order to determine the device is capable of performing the additional functionality. The system may prompt the user as to whether the additional functionality access should be granted. In response to receiving a confirmatory user input, the system may cause the access control system to grant the additional functionality access for the device.

Abstract: A pre-alarming method, a control method, and a control system for a harmful flow pattern in an oil and gas pipeline-riser system are provided. Support vector machines are trained. Through at least three pressure difference signals on the pipeline-riser system, an overall flow pattern in the pipeline-riser system is continuously and rapidly identified. Depending on monitoring on formation of a long liquid slug in a seabed pipeline and a quick response of the mean value of each pressure difference signal on a flow rate change, pre-alarming for a liquid slug caused by different mechanisms is realized, and liquid slug formation positions respectively of seabed pipeline and riser bottom are correspondingly pre-alarmed; after a pre-alarm is issued, there is enough time for a control device to respond, so as to avoid formation of the harmful flow pattern or damages caused by the harmful flow pattern.
