Topological analysis of the power grid and mitigation strategies against cascading failures
This paper presents a complex systems overview of a power grid network under cascading conditions. The cascading effect has been simulated on three different networks, the IEEE 300...

Catching Up Faster by Switching Sooner: A Prequential Solution to the AIC-BIC Dilemma
Bayesian model averaging, model selection and its approximations such as BIC are generally statistically consistent, but sometimes achieve slower rates of convergence than other m...

Capacity Regions and Bounds for a Class of Z-interference Channels
We define a class of Z-interference channels for which we obtain a new upper bound on the capacity region. The bound exploits a technique first introduced by Korner and Marton. A ...

Performance of Hybrid-ARQ in Block-Fading Channels: A Fixed Outage Probability Analysis
This paper studies the performance of hybrid-ARQ (automatic repeat request) in Rayleigh blockfading channels. The long-term average transmitted rate is analyzed in a fast-fading s...

Partition inequalities for capacitated survivable network design based on directed p-cycles
We study the design of capacitated survivable networks using directed p-cycles. A p-cycle is a cycle with at least three arcs, used for rerouting disrupted flow during edge failur...
