Abstract: Embodiments of this application disclose a data labeling system and method, and a data labeling manager. The system includes a data labeling manager, a labeling model storage repository, and a basic computing unit storage repository. The data labeling manager receives a data labeling request, obtains a target basic computing unit, allocates a hardware resource to the target basic computing unit, establishes a target computing unit, obtains first storage path information of basic parameter data of a first labeling model, and sends the first storage path information to the target computing unit. The target computing unit obtains the basic parameter data of the to-be-used labeling model by using the first storage path information, combines a target model inference framework and the basic parameter data of the first labeling model to obtain the first labeling model, and labels to-be-labeled data by using the first labeling model.

Abstract: An aqueous polyurethane dispersion compositions are disclosed. The compositions include a polyurethane prepolymer dispersed in an aqueous medium, the polyurethane prepolymer comprising an isocyanate and a crystalline polyester polyol having a hydroxyl content of 20 to 150 mg KOH/g and a melt temperature of less than or equal to 90° C.

The methods include providing an aqueous polyurethane dispersion, applying the polyurethane dispersion to a surface of the first substrate, bringing the side of the first substrate into contract with a surface of the second substrate, and curing the aqueous dispersion, thereby laminating the first substrate to the second substrate. Laminates formed by the methods and including the compositions are also disclosed.

Abstract: Disclosed is a reverse flow multi-stage sedimentation rake-free thickening device relating to the field of slime water treatment. The device includes a feed assembly, a guide assembly, and a clean coal collection assembly. The guide assembly also includes a central tank body and coal slurry flows from the upper part of the central tank body to the inner side wall of the central tank body through the feed assembly and the medicament, and then flows to the middle of the central tank body through the guide assembly. After the reaction, the bubbles carry the fine coal slime and move up to the clean coal collection assembly. The clean coal collection assembly is located above the outlet of the guide assembly, and the clean coal collection assembly is sequentially provided with a central collection area, a defoaming area, and a diversion settlement area from the middle to the outside.

Abstract: The present disclosure relates to a battery. The battery includes an encapsulation casing, a battery cell and a sealing cover. The encapsulation casing has an opening in an end thereof. The battery cell is arranged in the encapsulation casing. The sealing cover is bonded with the end of the encapsulation casing to seal the opening.

Abstract: This application provides a data stream connection method and apparatus. A join predicate between at least three data streams is determined based on attributes of the at least three data streams, a first connection order in which the at least three data streams are sequentially adjacent to each other is obtained based on the join predicate, and a data distribution of values of each attribute in the join predicate is determined. Subsequently, after a new tuple of any data stream is received, a data distribution corresponding to an attribute of the data stream is adjusted. Finally, the first connection order is adjusted to a second connection order based on the adjusted data distribution.
