With society's increasing dependence on critical infrastructure such as power grids and communications systems, the robustness of these systems has attracted significant attention. Failure of some nodes can trigger a cascading failure, which completely fragments the network, necessitating recovery e...

This paper presents an in-depth analysis of the interference strength and required guardband width between coexistent users for distributed orthogonal frequency division multiple access (OFDMA). In dynamic spectrum access networks, the cross-band interference between spectrally adjacent users is con...

With the development of large-scale complicated modern power systems, the requirement for the associated protection scheme tends to be more stringent and its combination more complex. However, it is very difficult to figure out the factors of failure of such systems. This paper proposes a Petri net ...

A modified Wilkinson power divider/combiner using one added stepped-impedance open-circuited radial stub on each branch is proposed for UWB applications. The stepped-impedance open stub is used to introduce multiple transmission poles through the whole UWB frequency spectrum. The simulation results ...

We analyze the outage for distributed estimation over orthogonal fading channels as a function of the number of sensors, K. We consider a scenario of fixed power per-sensor with an asymptotically large number of sensors. We characterize the scaling law of the outage and show that the outage decays f...
