A disadvantage of Link State routing schemes is that exact shortest path calculations require a complete topology, which can overload the capacity of small nodes in a large network. Area routing schemes (when destination names are structured corresponding to the network topology) allow nodes to reduce the size of routing tables, by recording only one entry for an entire region rather than one f...

It was discovered 12 years ago that type IIA topoisomerases can simplify DNA topology--the steady-state fractions of knots and links created by the enzymes are many times lower than the corresponding equilibrium fractions. Though this property of the enzymes made clear biological sense, it was not clear how small enzymes could selectively change the topology of very large DNA molecules, since t...

In order to achieve optimization control of complex network topology connection and to identify the network topology which with the greatest network connection gain, this paper proposes the network topology connection optimization control algorithm based on network efficiency and average connectivity. The algorithm uses network efficiency to characterize network connectivity gains, uses average...

We propose topology-based maps as a new representation of the workspace of a mobile robot. These maps capture the structure of the free space in the environment in terms of the basic topological notions of con-nectivity and adjacency. Topology-based maps can be automatically extracted from an occupancy grid built from sensor data using techniques borrowed from the image processing eld. Since th...

We reexamine the possibility of the detection of the cosmic topology in nearly flat hyperbolic Friedmann-Lemâıtre-Robertson-Walker (FLRW) universes by using patterns repetition. We update and extend our recent results in two important ways: by employing recent observational constraints on the cosmological density parameters as well as the recent mathematical results concerning small hyperbolic ...
