Key words: Topology optimization, multigrid methods, interior point methods, smoothing algorithms, checkerboard suppressionIn this paper, a new multigrid interior point approach to topology optimization problems in the context of the homogenization method is presented. The key observation is that nonlinear...

For Frame Relay point-to-point interfaces, set the bandwidth to the committed information rate (CIR). For Frame Relay multipoint connections, set the bandwidth to the sum of all CIRs, or if the permanent virtual circuits (PVCs) have different CIRs, set the bandwidth to the lowest CIR ...
We say that (X, · X ) has the Kadec-Klee property with respect to the weak topology (the Kadec-Klee property for short) if each sequence {xk}∞k=1 with limk xk X = 1, which converges weakly to a point x with x X = 1, tends strongly to x. The following theorem provides a...
We say that (X,‖⋅‖X) has the Kadec-Klee property with respect to the weak topology (the Kadec-Klee property for short) if each sequence {xn}n with limn‖xn‖X=1, which converges weakly to a point x with ‖x‖X=1, tends strongly to x. The following theorem provides a ...
That is, any topology in a nonempty set can induce the closure (interior) operator on its underlying powerset. It should be pointed out that closure and interior operators can be defined in a lattice (℘A,⊆) of all subsets of a set A with the set union as the join and the set...
In its last update, each neighbor will set an EOT signal so the restarting router knows that it has all available information and may begin the process of calculating routes. At this point, the restarting router exits "receive-only mode" and performs a Diffusing Update Algorithm (DUAL) ...
Point-to-point networks.Consist of two routers in which the point-to-point interfaces can be set up as numbered or unnumbered interfaces. A network of synchronous lines is an example of a point-to-point network. Broadcast networks.For networks with potentially more than two routers, but the ...
