An adjoint method for second-order switching time optimization
Abstract-- Switched systems evolve over a sequence of continuous modes of operation, transitioning between modes in a discrete manner. Assuming a mode sequence is known, the evolut...

Rapid and accurate latch characterization via direct Newton solution of setup/hold times
Characterizing setup/hold times of latches and registers, a crucial component for achieving timing closure of large digital designs, typically occupies months of computation in in...

Service Time Approximation in IEEE 802.11 Single-Hop Ad-hoc Networks
Abstract— This paper investigates the near-memoryless behavior of the service time for IEEE 802.11 saturated single-hop ad hoc networks. We show that the number of packets succes...

On-line adaptive optimal timing control of switched systems
Abstract— In this paper we consider the problem of optimizing over the switching times for a multi-modal dynamic system when the complete cost-to-go is not available. The instant...
