Abstract: A DFOS system and machine learning method that automatically localizes manholes, which forms a key step in a fiber optic cable mapping process. Our system and method utilize weakly supervised learning techniques to predict manhole locations based on ambient data captured along the fiber optic cable route. To improve any non-informative ambient data, we employ data selection and label assignment strategies and verify their effectiveness extensively in a variety of settings, including data efficiency and generalizability to different fiber optic cable routes. We describe post-processing steps that bridge the gap between classification and localization and combining results from multiple predictions.

Abstract: Disclosed are an aromatic amine derivative and an organic electroluminescent device including the same. A fluorenyl/silafluorenyl group having an ortho-substituted group is introduced into the structure of the aromatic amine derivative. The aromatic amine derivative may be used as a light-emitting material in a light-emitting layer of an organic electroluminescent device. These novel compounds can provide better device performance.

Abstract: This application provides a communication processing method for data transmission. A terminal-side device may adjust transmission of an uplink data burst in time based on time of arriving at an access stratum of the terminal-side device, a maximum peak rate, and a maximum data burst volume that are indicated by a network. This helps adapt to a network resource and improve a network load balancing capability.

Abstract: The improved bandwidth provisioning solution of the present invention enables the provision of bandwidth on demand by dynamically establishing and terminating one or more dynamic virtual circuits (SVCs) (137) to supplement a subscriber's default broadband connection. The improved bandwidth provisioning solution includes a client-side application (107) residing on the subscriber's data processing system (105) and a connection-management application (142) residing on a proxy signaling server (140). The client-side application (107) transmits a subscriber's request for a bandwidth-on-demand session to the connection-management application (142), which communicates with an asynchronous transfer mode (ATM) edge device (120) using User Network Interface (UNI) signaling to initiate the one or more VCs (137). When the subscriber no longer desires the additional bandwidth, the supplemental VCs (137) may be terminated.
