On myopic sensing for multi-channel opportunistic access: structure, optimality, and performance
We consider a multi-channel opportunistic communication system where the states of these channels evolve as independent and statistically identical Markov chains (the Gilbert-Elli...

Predictive representations for policy gradient in POMDPs
We consider the problem of estimating the policy gradient in Partially Observable Markov Decision Processes (POMDPs) with a special class of policies that are based on Predictive ...

Interconnect delay minimization through interlayer via placement in 3-D ICs
The dependence of the propagation delay of the interlayer 3-D interconnects on the vertical through via location and length is investigated. For a variable vertical through via lo...
