  • Publication number: 20150370923
    Abstract: A computer-implemented method for generating a computer model of a composite component includes offsetting a projected ply curved surface outwardly along a base surface to define an offset ply curved surface. The method also includes defining a ply drop region of the base surface, the ply drop region includes another area of the base surface that is exterior to a ply curved surface and interior to an offset ply curved surface. A surface mesh is generated based on the ply drop region and the ply curved surface. The method includes generating a node data comprising a plurality of node points relative to the ply drop regions. Moreover, the method includes applying a curved function to the plurality of node points to facilitate forming a smoothed node data across the ply drop region. A ply mesh is generated using the smoothed node data and the surface mesh.

  • Patent number: 9065757
    Abstract: A method for routing switch is disclosed. The method comprises: when a network device forwards traffic through N equal-cost multi-path (ECMP) routes to a destination, if M of these routes are inactive, then for each inactive route, determining an alternative route for replacing the inactive route from N-M active routes, and modifying the inactive route to the alternative route so as to switch the traffic of the inactive route onto the alternative route, wherein N and M are positive integer numbers, with N being greater than or equal to 2 and M being greater than or equal to 1 and smaller than N.

  • Publication number: 20150029855
    Abstract: The present disclosure relates to a traffic routing method and a traffic routing device. A member device of a stacking system receives traffic destined for a destination node. If there is at least one valid Equal-cost multi-path (ECMP) associated with an address of the destination node in a forwarding table, the member device routes the received traffic to the destination node through the at least one valid ECMP path. Otherwise, the member device selects at least one other member device of the stacking system for routing the received traffic, updates an ECMP path associated with the address of the destination node in the forwarding table to a stacking link connecting the member device with the selected at least one member device, and transmits the received traffic to the selected at least one member device.

  • Patent number: 8088437
    Abstract: Disclosed is a method for producing a silver-containing nanostructure which can reduce the time required for a post treatment step and the amount of a waste material and which is achieved by the application of the reduction reaction of silver oxide; and a silver-containing nanostructure having a specific structure, which can be produced by the method. Specifically disclosed is a method for producing a silver-containing nanostructure, including dispersing a polymeric compound in which a hydrophilic segment is bonded to a polyalkyleneimine chain in a medium, adding silver oxide thereto, and carrying out a reduction reaction of the silver oxide, thereby obtaining a silver-containing nanostructure. In the method, a structure having a branched structure can be produced when a specific compound is used as a complexing agent. The silver-containing nanostructure thus produced can be used as a conductive paste or the like.
