Topology-aware overlay path probing
Path probing is essential to maintaining an efficient overlay network topology. However, the cost of a full-scale probing is as high as O(n2 ), which is prohibitive in large-scale...

Towards Optimization of Probe Placement for Radio-Frequency Ablation
We present a model for the optimal placement of mono- and bipolar probes in radio-frequency (RF) ablation. The model is based on a numerical computation of the probe's electri...

An Optimal Randomised Cell Probe Lower Bound for Approximate Nearest Neighbour Searching
We consider the approximate nearest neighbour search problem on the Hamming cube {0, 1}d. We show that a randomised cell probe algorithm that uses polynomial storage and word size...
