Abstract: The present invention discloses a real-time evaluation method and evaluation system for group emotion homogeneity. The method comprises the steps as follows: enabling testees to be in the same emotion induction environment, and collecting the original electroencephalograph (EEG) signals of multiple persons at the same time through online multichannel EEG equipment; and based on the average instantaneous phase per second of the beta frequency band and the energy value per second of the alpha frequency band obtained after wavelet transformation, calculating the time synchronization degree and the valence consistency degree in real time, and finally obtaining a group emotion homogeneity index for the objective evaluation of group emotion homogeneity.

Abstract: This disclosure describes methods for growing cells on chickpea microcarriers as part of a process of creating a comestible food product. Generally, the disclosed method comprises adding chickpea microcarriers to cell culture media in a vessel. The chickpea microcarriers are mixed with non-human cells in the cell culture media. The chickpea microcarriers and non-human cells are mixed to adhere and grow the non-human cells on the surface of the chickpea microcarriers. After mixing, the non-human cells adhered to the surface of the chickpea microcarriers forms a textured cell tissue. The textured cell tissue can be harvested from the vessel and formed into a comestible food product.

Abstract: A bolster beam is correspondingly connected to a connection base by means of a damping unit; the radial dimensions of an outer wall of an inner supporting member and an inner wall of an outer supporting member gradually decrease from one end to the other end in a vertical direction; one of the inner supporting member and the outer supporting member is connected to the connection base, and the other one is connected to the bolster beam; when in use, the inner supporting member and the outer supporting member tend to be close to each other, and since surfaces, close to each other, of the two are configured to be tapered, the two can-not be relatively separated; when getting closer to each other, the inner supporting member and the outer supporting member produce a compression action on an intermediate buffer member, and the intermediate buffer member is elastically deformable.

Abstract: A draining device, which can discharge permeated water and/or rainwater quickly, and adapt to different construction requirements is provided. The draining device may have a permeable wall body. The permeable wall body may have a plurality of ribs, where a cross section of the ribs in a first direction is wavy, and a wave amplitude of the cross section gradually changes, from a first side to a second side, in a second direction. Therefore, the ribs have alternating wave crest parts and wave trough parts at either side of the first direction. The wave crest part of one rib, among two adjacent ribs is opposite to the wave trough part of the other. The first direction intersects the second direction. The second direction is a thickness direction of the permeable wall body.

Abstract: A coupler buffer device mounting structure for small-fastening-torque pushing under a compact space includes a double-headed stud passing through an installation fabrication hole of a vehicle body structure; a nut screwed on a first end of the double-headed stud; a push nut screwed on a second end of the double-headed stud and provided with a plurality of axial screw holes in a circumferential direction; and a plurality of push screws screwed into the circumferentially provided axial screw holes of the push nut, where the coupler buffer device is clamped and fixed to the vehicle body structure by heads abutting against the coupler buffer device via a hard washer. The coupler buffer device mounting structure achieves the passing of the double-headed stud from a coupler side to a vehicle body side by using the double-headed stud, the nut, the push nut and the plurality of push screws in combination.

Abstract: An embodiment of the present disclosure relates to a method for video anti-shake processing, an electronic apparatus and a storage medium, and the method includes: determining a moving track of a shooting position of a video by performing feature point tracking between different image frames in the video, wherein the moving track indicates shooting positions of the different image frames in the video; performing smoothing processing on a shooting position of each of the different image frames in the moving track, to obtain a smooth track; deforming the video based on a difference between the smooth track and the moving track, to obtain an anti-shake processed video, wherein at least one of the moving track and the smooth track is dynamically determined for the different image frames in the video.

Abstract: The present invention discloses a speech emotion recognition method and system based on fused population information. The method includes the following steps: S1: acquiring a user's audio data; S2: preprocessing the audio data, and obtaining a Mel spectrogram feature; S3: cutting off a front mute segment and a rear mute segment of the Mel spectrogram feature; S4: obtaining population depth feature information through a population classification network; S5: obtaining Mel spectrogram depth feature information through a Mel spectrogram preprocessing network; S6: fusing the population depth feature information and the Mel spectrogram depth feature information through SENet to obtain fused information; and S7: obtaining an emotion recognition result from the fused information through a classification network.

Abstract: A beverage mixing assembly for mixing a gas into a liquid to thereby form a solution includes a mixer body having a first upstream inlet configured to receive the gas, a second upstream inlet configured to receive the liquid, and a downstream outlet configured to dispense the solution from the mixer body. The first upstream inlet defines a first orifice configured to spray the gas into the mixer body and the second upstream inlet defines a second orifice configured to spray the liquid into the mixer body such that the gas collides into the liquid as the liquid conveys from the second upstream inlet to the downstream outlet to thereby mix into the liquid and form the solution.
