Talk slides from Pisa

Just realized that I neglected to put online the slides from my talks at the Symposium on Computational Geometry in Pisa a month ago. Here they are:

• Minimum Dilation Stars. Where to place the hub of a star-topology transportation network in order to minimize the ratio between straight-line distance and networked distance.
• The Skip Quadtree: A Simple Dynamic Data Structure for Multidimensional Data. Same material as the paper I uploaded a couple of days ago.

They're now also linked from the relevant entries in my online publications list.
