  • Graph-Based Node Classification Based on Connectivity and Topology
    Publication number: 20220247662
    Abstract: Techniques are disclosed for determining predictions from a graph of a network dataset. The graph of the network dataset may include nodes describing entities and edges describing connections or links between the entities. Predictions may be made using a dual-path convolution network that considers both node connectivity and node topology. Node topology includes assessment of similarities in topology roles between nodes in the graph, even nodes that reside in different parts of the graph. The node connectivity and node topology in the dual-path convolution may be aligned using a multi-head attention network. Outputs from previous layers of the multi-head attention network may be provided as inputs to subsequent layers of the dual-path convolution to mutually reinforce the convolutions determining node connectivity and node topology toward alignment.

  • HEAT EXCHANGE TUBE OF WASTE HEAT BOILER
    Publication number: 20220243908
    Abstract: Disclosed is a heat exchange tube of waste heat boiler, which includes a tube body. The outer surface of the tube body is sprayed with a layer of anti-corrosion coating. The components of the anti-corrosion coating are Al2O3, CaAl2O4 and Ca3(PO4)2. On the surface of nano anti-corrosion coating, HF reacts with Al2O3, CaAl2O4 and Ca3(PO4)2 to form AlF3 and Ca5(PO4)3F, which are tightly wrapped on the surface of the coating, thereby effectively preventing HF from corroding the interior of the coating and the heat exchange tube. Meanwhile, due to the anti-corrosion coating with the specific composition of the present disclosure, the heat exchange tube of the present disclosure can be resistant to fluorine corrosion at a high temperature of 600° C. or more, and can be used at a rather high temperature of 1000° C. or more.
