Abstract: The embodiments of the present disclosure provide a video content preview interactive method and apparatus, an electronic device, and a storage medium. A video-playing interface is displayed, a progress bar component is provided in the video-playing interface, and the progress bar component is used for displaying a playing progress of a target video played in the video-playing interface; a target caption corresponding to a target timestamp of the target video is displayed in response to a moving instruction for the progress bar component, where the moving operation indicates the target timestamp of the target video, and the target caption indicates video content of the target video at the target timestamp.

Abstract: Techniques and apparatus for parameter error detection in a power system based on state estimation are described. In one embodiment, for example, an efficient process may be used to derive and compute only the necessary subset of the gain matrix and covariance matrix, thus avoiding the computation and storage of large dense matrices. The described efficient process can be applied either to single-scan or multiple-scan schemes. Other embodiments are described.

Abstract: A method for communicating with a call center, is performed at a client device having one or more processors and memory. The client device establishes, via an instant messaging application running on the client device, a network session connection to the call center by using an audio and video server. The client device receives, through the network session connection, a first-level voice menu sent by the call center. The client device obtains a correspondence between visualized menus and voice menus of the call center. The device searches for a first visualized menu corresponding to the first-level voice menu according to the correspondence. The client device presents the first visualized menu in a user interface of the instant messaging application and plays information about an option in the first visualized menu in an on-demand voice manner in response to user input detected on the option in the user interface.
