Adjacency-Preserving Spatial Treemaps,ce in rectangular cartograms in which the rectangles represent geographic or political regions. A . is a rectangular layout with a hierarchical structure: the outer rectangle is subdivided into rectangles that are in turn subdivided into smaller rectangles. We describe algorithms for transforming a

Switching to Directional Antennas with Constant Increase in Radius and Hop Distance,adius 1, can be replaced by a strongly connected communication graph, in which each transceiver in . is equipped with a directional antenna of angle . and radius ., for some constant .. Moreover, the new communication graph is a .-spanner of the original graph, for some constant . = .(.), with respect to number of hops.

Multicut in Trees Viewed through the Eyes of Vertex Cover,s us to significantly improve the .(..) upper bound on the kernel size for ., given by Bousquet et al., to .(..). We exploit this connection further to present a parameterized algorithm for . that runs in time ..(..), where .. This improves the previous (time) upper bound of ..(2.), given by Guo and Niedermeier, for the problem.
