On the Union of Cylinders in Three Dimensions
We show that the combinatorial complexity of the union of n infinite cylinders in R3 , having arbitrary radii, is O(n2+ε ), for any ε > 0; the bound is almost tight in the w...

Modeling Fiber Delay Loops in an All Optical Switch
We analyze the effect of a few fiber delay loops on the number of deflections in an all optical packet switch. The switch is based on the ROMEO architecture developed by Alcatel...

On Geometric Dilation and Halving Chords
Let G be an embedded planar graph whose edges may be curves. The detour between two points, p and q (on edges or vertices) of G, is the ratio between the shortest path in G between...

Approximation Schemes for Minimum 2-Connected Spanning Subgraphs in Weighted Planar Graphs
Abstract. We present new approximation schemes for various classical problems of finding the minimum-weight spanning subgraph in edge-weighted undirected planar graphs that are re...

Gang EDF Scheduling of Parallel Task Systems
The preemptive real-time scheduling of sporadic parallel task systems is studied. We present an algorithm, called Gang EDF, which applies the Earliest Deadline First (EDF) policy ...
