Abstract: The present invention relates to a positive electrode material comprising a core material and a coating layer coated on the surface of the core material, the core material comprises nickel hydroxide, and the coating layer comprises a tetravalent cobalt compound; and based on the weight of the coating layer, the content of the tetravalent cobalt compound is no less than 45 wt %. The present invention also relates to a preparation method for the positive electrode material. The present invention further relates to an alkaline secondary battery containing the positive electrode material.

Abstract: Computer-implemented systems and methods for generating a mesh and conformally connecting the mesh to an existing mesh are provided. The existing mesh is displayed via a graphical user interface (GUI) of a computer-aided design modeling system using a processing system. A polyhedral mesh is generated in an empty space adjacent to the existing mesh using the processing system. The generating of the polyhedral mesh includes (i) defining the empty space as a first surface mesh comprising triangles, quadrilaterals, polygonals, or a mixture thereof, (ii) generating a dual of the first surface mesh to form a second surface mesh, the empty space being enclosed by the second surface mesh, and (iii) filling a gap region between the first and second surface meshes with the polyhedral mesh and conformally connecting the polyhedral mesh to the existing mesh using the processing system.

Abstract: A method for compressing a machine learning model by an electronic device. The method may comprise determining a compression parameter of a set hidden layer in a model based on a pruning number of respective channels included in the set hidden layer and a pruning loss of each hidden layer of the model; and compressing the model based on the compression parameter of the set hidden layer. The compression parameter may be related to a pruning of the model.

Abstract: A formula inputting method is provided. The formula inputting method includes receiving a handwriting input of a user; obtaining handwriting content based on the handwriting input of the user; determining at least one or more recommended content based on the handwriting content; and displaying the handwriting content and the one or more recommended content.
