Abstract: Provided are an interaction method and apparatus in a live streaming room, a device, and a storage medium. The method comprises: in response to a trigger operation for a preset drawing entry on a live streaming room page, jumping to a graphic drawing page from the live streaming room page, a drawing trajectory set for a preset object being displayed on the graphical drawing page; when a drawing stroke on the graphic drawing page is received, matching the drawing stroke with the drawing trajectory; and if it is determined that the drawing stroke is successfully matched with the drawing trajectory, displaying prompt information about successful participation in a preset activity, the preset activity and the preset drawing entry having a correspondence.

Abstract: Provided are a vibration object monitoring method and apparatus, a computer device, and a storage medium. The method includes: in response to detecting that a vibration object exists in a monitoring video picture for a target monitoring region, a vibration object region in the monitoring video picture is determined, where the vibration object region is a region where the vibration object is located in the monitoring video picture; displacement information of a key point of the vibration object in the vibration object region is recorded; vibration information of the vibration object in the monitoring video picture is determined based on the displacement information; and a vibration object monitoring result for the target monitoring region is generated according to the vibration information. The abnormal vibration monitoring can be performed on the vibration object in the target monitoring region in time according to this method.

Abstract: The present disclosure provides a live-stream interaction method, a live-stream interaction system and related devices. The system includes a terminal of an audience, a terminal of an anchor, and a server; the terminal of the audience is configured to present a live-stream interface, and the live-stream interface includes an interaction control that supports interaction, and when the audience triggers an interactive behavior through the interaction control, an interaction image when the audience performs the interactive behavior is acquired; the terminal of the anchor is configured to send the behavior feature of the anchor to the server; the server is configured to acquire the behavior feature of the audience, match the behavior feature of the audience with the behavior feature of the anchor to obtain a matching result, and send a special effect instruction to the terminal of the audience according to the matching result.

Abstract: The present invention discloses a method and device for formulating a coordinated action strategy of SSTS and DVR for voltage sag mitigation. The influence of voltage sag on a whole industrial process of a sensitive user is analyzed, and the sensitive loads of SSTS and DVR which satisfy a governance need are grouped; a practical governance scenario of installing a plurality of DVR is considered to install a minimum-capacity DVR to realize a target of a minimum interruption probability of the whole industrial process of the user; an optimal coordinated governance solution of SSTS and DVR based on sensitive load grouping is proposed; a classification result is obtained for duration time at a time when a voltage sag event occurs through a decision tree constructed based on historical data.

Abstract: A sleeve mold for a method of high-throughput hot isostatic pressing micro-synthesis for combinatorial materials includes a honeycomb-array-sleeve and an upper cover, wherein a plurality of single cells are tightly arranged inside the honeycomb-array-sleeve, an exhaust tube is arranged on the upper cover, after the single cells are filled with powder materials, the upper cover is sealed welding on the honeycomb-array-sleeve, and the honeycomb-array-sleeve and the upper cover are both integrally produced by additive manufacturing. According to the method and the sleeve mold, the powder metallurgy hot isostatic pressing process is utilized to prepare small-size bulk combinatorial materials with multiple discrete components rapidly at one time.

Abstract: The invention relates to a method of high-throughput hot isostatic pressing micro-synthesis for the combinatorial materials and a sleeve mould thereof. The sleeve mould (2) comprises a honeycomb-array-sleeve (3) and an upper cover (4), wherein a plurality of single cells (6) are tightly arranged inside the honeycomb-array-sleeve (3), an exhaust tube (5) is arranged on the upper cover (4), after the single cells (6) are filled with powder materials, the upper cover (4) is sealed welding on the honeycomb-array-sleeve (3), and the honeycomb-array-sleeve (3) and the upper cover (4) are both integrally produced by additive manufacturing. According to the method and the sleeve mould, the powder metallurgy hot isostatic pressing process is utilized to prepare small-size bulk combinatorial materials with multiple discrete components rapidly at one time. This method has the characteristics of high sintering speed, high compaction density, good thermal diffusivity, short production cycle and low material consumption.
