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...
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...
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...

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...
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 ...
