Adaptive Importance Sampling Technique for Markov Chains Using Stochastic Approximation
For a discrete-time finite-state Markov chain, we develop an adaptive importance sampling scheme to estimate the expected total cost before hitting a set of terminal states. This s...

Simulating GI/GI/1 queues and insurance risk processes with subexponential distributions
This paper deals with estimating small tail probabilities of the steady-state waiting time in a GI/GI/1 queue with heavy-tailed (subexponential) service times. The problem of esti...

Queue Proportional Scheduling via Geometric Programming in Fading Broadcast Channels
For fading broadcast channels (BC), a throughput optimal scheduling policy called queue proportional scheduling (QPS) is presented via geometric programming (GP). QPS finds a data ...

Reducing data cache energy consumption via cached load/store queue
High-performance processors use a large set–associative L1 data cache with multiple ports. As clock speeds and size increase such a cache consumes a significant percentage of t...
