  NationMaster - Encyclopedia: Continuous function (topology)
In topology and related fields of mathematics, a discrete space is a particularly simple example of a topological space or similar structure, one in which the points are isolated from each other in a certain sense.
In topology and related areas of mathematics, the initial topology (projective topology or weak topology) on a set, with respect to a family of functions on, is the coarsest topology on X which makes those functions continuous.
In topology and related areas of mathematics, a subspace of a topological space X is a subset S of X which is equipped with a natural topology induced from that of X called the subspace topology (or the relative topology, or the induced topology).

 IDD Topology Reconfiguration Plan
The original topology for the IDD was put together before Unidata had much practical experience with large volume dataflows over the internet.
However, we can implement a new topology that is well thought out and valid for current conditions, such as they are.
This entails designing a topology based on some initial assumptions that may, or may not be valid.

  Final topology - Wikipedia, the free encyclopedia
In topology and related areas of mathematics, the final topology (inductive topology or strong topology) on a set X, with respect to a family of functions into X, is the finest topology on X which makes those functions continuous.
The quotient topology is the final topology on the quotient space with respect to the quotient map.
The disjoint union is the final topology with respect to the family of canonical injections.

 Comparison of topologies - Wikipedia, the free encyclopedia
All possible polar topologies on a dual pair are finer than the weak topology and coarser than the strong topology.
The join, however, is not generally the union of those topologies (the union of two topologies need not be a topology) but rather the topology generated by the union.
In the case of topologies, the greatest element is the discrete topology and the least element is the trivial topology.

The simplest of the complex topologies is developed by serially interconnecting all the hubs of a network, as shown in Figure 5.6.
The parallel backbone topology is a modification of the collapsed backbone.
Ultimately, however, the successful topology is driven by the users' required performance levels and tempered with other considerations like cost, expected future growth, and technology limitations.

Two networks are taken from a run, the first viable topology that can calculate the objective function and the final winning topology in the run (which is usually generation 499).
While both of these topologies can compute the square root exactly, chance mutations may have given the second topology a set of rate constants that allowed it to compute the square root more accurately.
Finally, the network is shown with the adjusted rate constants that allow it to compute an exact square root.

 Top-down Hierarchical Topologies
BRITE uses an edge connection mechanism to interconnect router-level topologies as dictated by the connectivity of the AS-level topology.
The final topology is obtained by flattening the hierarchical topology into a router-level topology composed of the individual topologies associated with each node at the AS-level.
Note that we are implicitly assuming that the topology being manipulated is represented by an undirected graph.

 BioMed Central | Full text | Long branch attraction, taxon sampling, and the earliest angiosperms: Amborellaor monocots?
Finally, it should be noted that ML and NJ methods using models (see next section) that give Amborella-sister when only grasses represent monocots, continue to do so, but with higher BS, when Acorus is added, either with or without grasses [see Additional files 1 and 2].
The Amborella-sister topology is in agreement with the many diverse phylogenetic studies summarized in Table 1 and in Background, except for that of Goremykin et al.
This iteration was continued until the last two topologies converged (the final ML topology was almost always equal to the one in which the ML parameters were estimated from the parsimony topology).

Unlike the other topologies here, ring systems are generally built assuming the machines are all nearby on the network and owned by a single organization.
The final topology we consider here is decentralized systems, where all peers communicate symmetrically and have equal roles.
By looking at systems in terms of their topology, it is possible to examine a wide spectrum of systems we have on the Internet today, from centralized to decentralized and with architectures in between.

Finally, the tool was applied to the first entirely sequenced genome of Haemophilus influenzae (Fleischmann et al., 1995) and particular aspects of the results were compared to an analysis of the yeast VIII chromosome (Rost et al., 1995).
Crosses mark proteins for which all segments and the topology were predicted correctly; filled triangles proteins for which the topology prediction was wrong although all helices were correctly predicted; open circles proteins for which some helices and the topology were predicted falsely.
The final prediction of topology was assigned according to the sign of the difference between the number of charged residues in odd and even regions.

 Deployment Guide: Planning Your Environment
The simplest NAS topology is one that consists of a single machine on which you have installed a web server, a Netscape Application Server, and a back-end data source.
Another simple topology that improves on performance by easing the load is one in which the web server and a single installation of NAS reside on the same machine, while the back-end data source is on another machine.
The following topology consists of three separate machines: the web server is installed on one machine, a single installation of NAS is installed on the second machine, and the back-end data source is installed on the third machine.

 Aquaporin 1
AQUAPORIN 1 BIOGENESIS involves a novel variation in the cotranslational folding model in which the initial topology of TM segments as they emerge from the ribosome differs from their final topology in the mature protein.
Similarly, it is unknown whether this change in topology is driven by the energy of helical packing other aspects of protein folding.
Topology of each TM segment is established independently and no reorientation of topology occurs.

 How to upgrade a heighfield terrain - GameDev.Net Discussion Forums
So this is just your arbitrary topology control mesh - the final surface mesh is generated by applying the subdivision rules to the control mesh up to the desired level of tessellation (for catmul-clark subdivision surfaces, one level of subdivision divides each square patch into four smaller square patches).
The subdivision rules ensure that the final surface is smooth everywhere, but since smooth is boring you could add surface roughness with something like fractal displacements along the surface normals.
The hierarchical idea of topology changes is described in part 2 of http://cm.bell-labs.com/who/wim/papers/hybrid/ (the rest of paper is not relevant).

 Continuous function (topology) - Wikipedia, the free encyclopedia
In topology and related areas of mathematics a continuous function is a morphism between topological spaces.
The most common notion of continuity in topology defines continuous functions as those functions for which the preimages of open sets are open.
If S has an existing topology, f is continuous with respect to this topology if and only if the existing topology is coarser than the final topology on S.

 Optical Networks Magazine - Abstracts from Volume 3, Issue 3
Given the optical network topology and traffic forecast for optical connections, a network design must choose routes for the connections in the forecast (called demands in this context) over network capacity with the objective of minimizing the cost of placing capacity.
We assume that the network topology for a future traffic demand is given and formulate an integer programming-based design problem to minimize the total facility cost for the current traffic demand.
From the simulation results, it is inferred that SGP is useful in network topologies, such as mesh-torus, characterized by good connectivity and a good amount of traffic switching and mixing at the nodes.
