  • Publication number: 20250238281
    Abstract: A task unloading method based on unmanned aerial vehicle cooperation is provided. The method includes: establishing an unmanned aerial vehicle cooperation task unloading system; establishing, for each of ground users, a local task unloading model of the ground user; establishing, for each of the ground users, an unmanned aerial vehicle task unloading model of the ground user; establishing a hovering model of the unmanned aerial vehicles; and calculating an optimal task unloading assignment solution by using a second price auction algorithm to perform task unloading. With the method, task unloading is performed based on unmanned aerial vehicle mobile edge computing, improving the quality of service and the service experience of the users.

  • Patent number: 5351749
    Abstract: An arrangement of apparatus and process thereof for cooling hot fluid solid particles, especially hot regenerated catalytic particles are disclosed. The apparatus comprises a substantially vertical, cylindrical and close ended heat removal vessel through the shell sid passage of which is passed the fluid solid particles that flow downwardly in the form of dense phase fluidized bed, and one or more seperate heat exchange tube units through the tube side passage of which the coolant is passed and evaporized, each of said heat exchange tube units comprising a supply coolant inlet tube, a supply coolant collecting chamber, one or more heat exchange tubes, a vapour collecting chamber and a resulting vapour discharge tube, all of which constitute a close type coolant-to-vapour circulation.
