Early Estimates of the Size of Branch-and-Bound Trees
This paper intends to show that the time needed to solve mixed integer programming problems by branch and bound can be roughly predicted early in the solution process. We construc...

Estimating clock uncertainty for efficient duty-cycling in sensor networks
Radio duty cycling has received significant attention in sensor networking literature, particularly in the form of protocols for medium access control and topology management. Whi...

An atmosphere-ocean time series model of global climate change
Time series models of global climate change tend to estimate a low climate-sensitivity (equilibrium effect on global temperature of doubling carbon dioxide concentrations) and a f...

Practical stability of time delay systems: LMI's approach
— In this paper we discuss the practical stability of a class of time delay systems with an unstable equilibrium. We obtain sufficient conditions based on Lyapunov-Krasovskii fu...

Performance Limits of Time Synchronization in Wireless Sensor Networks
—We propose a new approach to evaluate the ultimate performance limit of time synchronization in wireless sensor networks based on the estimation theory. In particular the lower ...
