Abstract: A computer program product, system, and method for building a knowledge graph may include receiving a plurality of new nodes, receiving a base knowledge graph having existing nodes selectively connected by existing edges, and superimposing the new nodes onto selected ones of the existing nodes of the base knowledge graph. The method may further include connecting the new nodes by creating a new edge with a new weight between at least two of the new nodes if corresponding existing nodes in the underlying base knowledge graph have a connection via zero or a predetermined maximum number of existing edges, wherein the new weight is determined based on the existing weights of the existing edges of connections between the corresponding existing nodes, and detaching the new nodes with the new edges from the base knowledge graph.

Abstract: A cable is used, in particular, as an underwater cable and contains a central element, which is surrounded by a cable sheath. The cable sheath has an inner hydrophobic sheath layer made of a first plastic and an outer sheath layer applied to same and made of a different plastic to the inner sheath layer. A polyolefin-type plastic is used for the inner sheath layer and one of the sheath layers, in particular the inner sheath layer is chemically functionalized, and a sealed connection is formed between the two sheath layers.

Abstract: A method of producing an elastomeric optical conductor fiber composed of plastic includes drawing a fiber composed of a high-viscosity liquid reactive starting material. The starting material is added by way of a nozzle to a reaction apparatus, to which a liquid, which is inert towards the starting material, has been charged. At least partial crosslinking of the starting material takes place in the reaction apparatus. The elastomeric plastic of the optical conductor fiber is in particular a three-dimensionally crosslinked polyurethane.
