Abstract: The disclosure generally describes methods, software, and systems for processing information received from Internet of Things (IoT) devices, including a computer-implemented method in which information is received in a semantic recognition system (SRS). The information includes a device identifier (ID) of a first device, a payload containing information transmitted by the first device, and semantic information associated with the first device. A semantic model for the first device is determined by the SRS using the device ID and the semantic information. A digital twin representing the first device is generated by the SRS.

Abstract: Activated support materials are provided containing oxirane or azlactone groups as substituents in linear polymers as activated groups. A base support containing hydroxyl groups is suspended in a solution containing cerium (IV) ions and a monomer containing an oxirane or azlactone group, and grafting polymerization is carrier out to produce a polymer containing oxirane or azlactone groups covalently bonded to the base support. Azlactone groups can be bonded to the base support via a thioether bond by using a base support containing thiol groups. The activated support materials can be used to prepare affinity supports containing an affinity ligand that is thiophilic or possesses a metal chelating group, or to prepare immobilized enzymes. The ligand can be iminodiacetic acid, or can be obtained by reacting an oxirane group of the support material with NaHS, and reacting the resultant product with divinylsulfone followed by reacting with mercaptoethanol.
