Abstract: A component and a system for mitigating coke formation during delivery of a hydrocarbon fluid. The component includes a contact surface configured to be in contact with the hydrocarbon fluid. Tuning the zeta potential of the contact surface allows selective attraction and/or repulsion of coke-catalyzing materials, metal ions, heteroatomic hydrocarbons, and/or coke precursors present in the hydrocarbon fluid. A method of mitigating coke formation during delivery of a hydrocarbon fluid includes tuning a zeta potential of the contact surface of the component and injecting or circulating the hydrocarbon fluid through the system such that the contact surface selectively attracts and/or repels coke-catalyzing materials, metal ions, heteroatomic hydrocarbons, and/or coke precursors present in the hydrocarbon fluid.

Abstract: A system can monitor event data corresponding to a current user experience of a requesting user during a current application session with a network service. Based on the event data, the system generates one or more representations corresponding to the current user experience of the requesting user, and executes a machine learning model to process the one or more representations in order to predict a negative user experience for the requesting user within a future time frame during the current application session. In response to predicting the negative user experience, the system implements one or more corrective actions during the current application session through the service application to prevent or mitigate the predicted negative user experience.

Abstract: A computing system can receive event data corresponding to a user's experience with a network service. Based on the event data, the system can generate a set of representations that correspond to the user's experience with the network service. The representations may be analyzed and/or filtered by an artificial intelligence model executing on the computing system, which can predict negative experiences of users at future time intervals. Based on these predictions, the computing system can implement a set of corrective actions to steer the user experience to a more positive path.

Abstract: A network computer system for managing a network service (e.g., a transport service) can include a voice-assistant subsystem for generating dialogues and performing actions for service providers of the network service. The network computer system can receive, from a user device, a request for the network service. In response, the network computer system can identify a service provider and transmit an invitation to the provider device of the service provider. In response to the identification of the service provider for the request, the voice-assistant subsystem can trigger an audio voice prompt to be presented on the provider device and a listening period during which the provider device monitors for an audio input from the service provider. Based on the audio input captured by the provider device, the network computer system can determine an intent corresponding to whether the service provider accepts or declines the invitation.

Abstract: A network computer system can respond to a call connection signal by making a determination as to whether the call connection is likely to be supported for at least one of the caller or receiver using a first voice communication medium, as compared to an alternative voice communication medium. Based on the determination, the network computer system can cause the call connection to be established using the voice communication medium of the determination.

Abstract: A network computer system operates to generate synthetic messages based on service-specific information. The network computer system communicates with user devices, including requester devices and provider devices, to match service requests generated by the requester devices to respective service provider entities associated with the provider devices. For a given service request generated by a respective requester device, the network computer system determines service-specific information using device data communicated by at least one of the respective requester device and a respective provider device. The respective provider device is associated with a service provider entity that is matched to the given service request. The network computer system detects a trigger based on the service-specific information.

Abstract: A system and method are provided for monitoring traffic in an enterprise network. Similar hosts may be grouped using flow information. Network policy may then be created at the group level based on the signatures of the hosts and groups of hosts in the enterprise. Hosts may be arranged in hierarchical clusters. Some of these clusters may be selected as groups based on a desired degree of similarity between hosts in a group. The similarity between hosts may be determined based on similarity of network behavior of the hosts.

Abstract: A method of controlling minority carrier lifetime in a semiconductor device in which the density of recombination centers is controlled so that the recombination centers are concentrated in a thin buffer layer adjacent a blocking layer in one of two bonded wafers. The density is controlled by misaligning crystal axes of the two wafers or by doping the bonding surface of one of the wafers before the wafers are bonded. Both methods generate recombination centers in the thin buffer layer that forms around or adjacent the bonding interface. A semiconductor device made by this method includes a buffer layer with a significantly higher density of recombination centers than the adjacent blocking layer to thereby improve control of minority carrier lifetime.
