Note that the image of a closed set is not necessarily closed for continuous functions, and the image of a bounded set is not necessarily bounded.
However, the image of a close and bounded set is again closed and bounded (under continuous functions).
Thus, the image of every connected set under a continuous function is connected.

 IEEE Transactions on Parallel and Distributed Systems,October 2004 (Vol. 15, No. 10)
Efficient routing among a set of mobile hosts is one of the most important functions in ad hoc wireless networks.
Routing based on a connected dominating set is a promising approach, where the search space for a route is reduced to the hosts in the set.
Rule k is more effective in reducing the dominating set derived from the marking process than the combination of Rules 1 and 2 and, surprisingly, in a restricted implementation with local neighborhood information, Rule k has the same communication complexity and less computation complexity.

 FSTTCS2000: Abstract for Paper 15   (Site not responding. Last check: 2007-10-14)
When edges are unit-weighted, the edge dominating set problem is polynomially equivalent to the minimum maximal matching problem, in either exact or approximate computation, and the former problem was recently found to be approximable within a factor of 2.1 even with arbitrary weights.
The connected edge dominating set problem and the connected vertex cover problem also have the same approximability when edges/vertices are unit-weighted, and the former problem is known to be approximable, even with general edge weights, within a factor of 3.598.
We will show that, when general weights are allowed, 1) the connected edge dominating set problem can be approximated within a factor of $3+\epsilon$, and 2) the connected vertex cover problem is approximable within a factor of $3+\ln n$ but cannot be within $(1-\epsilon)\ln n$ for any $\epsilon >0$ unless $\mbox{NP}\subset \mbox{DTIME}(n^{O(\log\log n)})$.

 Polynomial-Time Approximation Scheme for Minimum Connected Dominating Set in Ad Hoc Wireless Networks - Cheng, Huang, ...
Abstract: A connected dominating set in a graph is a subset of vertices such that every vertex is either in the subset or adjacent to a vertex in the subset and the subgraph induced by the subset is connected.
The minimum connected dominating set is such a vertex subset with minimum cardinality.
An application in ad hoc wireless networks requires the study of the minimum connected dominating set in unit-disk graphs.

The mode decomposition of the electromagnetic field connected with a sphere is considered.
The continuity requirements of the field across the surface of the sphere lead to a certain set of so called natural modes, which can be calculated explicitly if the radial part of the electric field strength inside the sphere equals zero.
The completeness of this set of functions, which is necessary to solve an initial value problem, will be shown.

 Content of JGA
We present two strategies for producing and describing some connected non-locally connected Julia sets of infinitely renormalizable quadratic polynomials.
By using a more general strategy, we prove that all of these Julia sets fail to be arc-wise connected, and that their critical point is non-accessible.
The limit Julia set resembles in a certain way the classical non-locally connected set: "the topologists spiral." A weaker result is obtained using the second strategy: the existence of polynomials having an explicitly given external ray accumulating at a particularpoint, but having in its impression the symmetric point as well.

In this paper three sufficient conditions are provided under each of which an upper semi-continuous point-to-set mapping defined on an arbitrary polytope has a connected set of zero points that connect two distinct faces of the polytope.
Furthermore, we obtain an existence theorem of a connected set of solutions to a nonlinear variational inequality problem over arbitrary polytopes.
The algorithm operates on a triangulation of the polytope and generates a piecewise linear path of points connecting two distinct faces of the polytope.

NEW YORK -- The prospect of homes where the refrigerator can be used to surf the Internet came one step closer, when major computer and electronics manufacturers said they had united on a standard for turning a home's electrical wiring into a data network.
Several companies sell kits that connect computers through phone jacks, allowing them to share files, printers and an Internet connection, much like in an office.
But most homes have a small number of phone jacks, limiting the number of machines that can be connected, and pulling additional data cables between rooms is an unappealing option.

It is our belief that the PCs of today are the tools that will evolve into the information "appliances" of the future enabling individuals to retrieve information quickly from the vast resources on the Internet and becoming the interface that will operate the home entertainment system of the future.
These clients will probably not be the prophesied $200 appliances we have all heard about, but rather more robust complete multimedia personal productivity systems that will not only use the resources of the home server (for high-speed Internet access, printer and storage needs) but also will synchronize with one's Internet capable cellular phone/organizer.
