Abstract: A flexible electroluminescent fiber for embroidery sequentially includes: metal core wires, a light-emitting layer, a transparent conductive layer, a filament, and a protective paint, wherein a quantity of the metal core wires is an even number, and the metal core wires are pasted together before being wrapped by the light-emitting layer; the light-emitting layer is coated with the transparent conductive layer; the protective paint and the filament are exterior to the transparent conductive layer; the metal core wires emit light through energizing; a diameter of the electroluminescent fiber is 0.1-0.3 mm, and a 20-36V safe voltage is applied for emitting light. The flexible electroluminescent fiber of the present invention has sufficient tensile force, and smooth and soft surface. Appearance and hand feeling of the present invention are the same as those of clothing textile fibers.

Abstract: A method for knowledge representation and deduction of service logic includes: generating, based on a knowledge representation model, a semantic graph corresponding to conceptual-layer service logic, where the semantic graph includes one or more types of nodes and edges for connecting the one or more types of nodes, and the nodes include at least a node of a variable type; generating, based on the semantic graph and a physical table to which a service object is mapped, an instance graph, where the instance graph includes the nodes and edges in the semantic graph; generating executable code based on a service logic relationship between the nodes in the instance graph; and determining, based on the executable code and a data instance corresponding to a node whose in-degree is 0 in the instance graph, a data instance corresponding to each node in the instance graph.
