Directional Versus Omnidirectional Antennas for Energy Consumption and k-Connectivity of Networks of Sensors
A network is k-connected if it remains connected after the removal of any k - 1 of its nodes. Assume that n sensors, modeled here as (omni)directional antennas, are dropped random...

A Class of stochastic programs with decision dependent uncertainty
We address a class of problems where decisions have to be optimized over a time horizon given that the future is uncertain and that the optimization decisions influence the time o...

A Metastability-Free Multi-synchronous Communication Scheme for SoCs
We propose a communication scheme for GALS systems with independent but approximately synchronized clock sources, which guarantees high-speed metastability-free communication betwe...

Estimation of maximum current envelope for power bus analysis and design
In this paper we present an input pattern independent method to compute the maximum current envelope, which is an upper bound over all possible current waveforms drawn by a circui...
