Abstract: There are provided systems and methods for pairwise graph querying, merging, and computing for account linking. A service provider may provide an account graph system to identify pairwise similarities between different accounts based on shared data that may be identified through one or more linking characteristics. When providing pairwise graph similarities, a service provider may receive a query identifying two or more accounts and/or an account with a parameter for graph exploration and querying. The service provider may utilize connection, link, or relationship graphs, queried and generated using a graph database, to determine pairwise similarities between the designated seed account and one or more selected accounts. The graph may include vertices for different queried data points and edges connecting such queries, where directionality of the edges or other vectors may be used to identify links or hops between accounts for data querying and exploration.

Abstract: A tomography system having a central processing unit, a system memory communicatively connected to the central processing unit, and a hardware acceleration unit communicatively connected to the central processing unit and the system memory, the hardware accelerator configured to perform at least a portion of an MBIR process on computer tomography data. The hardware accelerator unit may include one or more voxel evaluation modules which evaluate an updated value of a voxel given a voxel location in a reconstructed volume. By processing voxel data for voxels in a voxel neighborhood, processing time is reduces.

Abstract: A method, system and non-transitory computer-readable storage medium for switching video live broadcasting to on-demand broadcasting are provided. The method includes: receiving a live broadcasting to on-demand broadcasting conversion request, and parsing a video characteristic parameter of a video to be broadcast on demand, querying an index table to determine a storage address of a video file corresponding to the video characteristic parameter of the video to be broadcast on demand; finding a corresponding source live broadcasting video file based on the determined storage address of the video file, and generating an on-demand broadcasting file by use of the corresponding source live broadcasting video file.

Abstract: Disclosed is a method and electronic device for bandwidth allocation. The method includes, at an electronic device: receiving a service access request from a user; parsing the request to determine the user's service attribute which at least includes a requested bandwidth, a currently occupied bandwidth and a priority; and determining a strategy for bandwidth allocation, including: determining a predetermined available bandwidth for the determined priority, comparing a sum of the requested bandwidth and currently occupied bandwidth with the available bandwidth, and refusing to allocate the requested bandwidth if the sum of the requested bandwidth and currently occupied bandwidth is greater than the available bandwidth, or otherwise allocating the requested bandwidth. The embodiments of the disclosure show the method and electronic device for bandwidth allocation in question, which allocate user's bandwidth in a dynamic manner, realize efficient utilization thereof and avoid wastes therefrom.

Abstract: Disclosed is a method for providing video service, including receiving by a video server an access request from a client; forwarding the access request to a client server of the client for authentication; receiving an authentication feedback fed back by the client server; and determining whether to provide a video service at least according to the authentication feedback. In addition, the disclosure also provides a method for access authentication, a video server, a client server and a video access system. The disclosure can solve the security hazard of leakage of user information and overload of a video server in the prior art.

Abstract: The present disclosure provides a method and system for distributing a video and interacting with a media resource system. The method includes: distributing and storing a transcoded video, obtaining a distributed storage address of the video and generating a notification message using the obtained address and adding the notification message to a queue of messages; and searching for and distributing the video corresponding to the distributed storage address in the notification message upon monitoring that the notification message in the queue of messages is read by the media resource system, if the distribution of the video is finished, deleting the notification message corresponding to the video from the queue of messages, or if the distribution of the video is interrupted, putting the notification message corresponding to the video at the end of the queue of messages to wait for processing. Present invention solves the issue that media resource system interaction.
