Quantum Circuits with Unbounded Fan-out
We demonstrate that the unbounded fan-out gate is very powerful. Constant-depth polynomial-size quantum circuits with bounded fan-in and unbounded fan-out over a fixed basis (denot...

Ray-Tracing Triangular Trimmed Free-Form Surfaces
This paper presents a new approach to rendering triangular algebraic free form surfaces. A hierarchical subdivision of the surface with associated tight bounding volumes provides ...

Symbolic performance analysis of elastic systems
Elastic systems, either synchronous or asynchronous, can be optimized for the average-case performance when they have units with early evaluation or variable latency. The performan...

Truthful Mechanisms for Exhibitions
We consider the following combinatorial auction: Given a range space (U, R), and m bidders interested in buying only ranges in R, each bidder j declares her bid bj : R R+. We give...

Crossing Number and Weighted Crossing Number of Near-Planar Graphs
A nonplanar graph G is near-planar if it contains an edge e such that G−e is planar. The problem of determining the crossing number of a near-planar graph is exhibited from diffe...
