An Efficient Scheme to Reduce Handoff Dropping in LEO Satellite Systems
The problem of handoffs in cellular networks is compounded in a low earth orbit (LEO) satellite-based cellular network due to the relative motion of the satellites with respect to ...

A Disk-Covering Problem with Application in Optical Interferometry
Given a disk O in the plane called the objective, we want to find n small disks P1, . . . , Pn called the pupils such that n i,j=1 Pi Pj ⊇ O, where denotes the Minkowski diffe...

Decentralised Learning MACs for Collision-free Access in WLANs
By combining the features of CSMA and TDMA, fully decentralised WLAN MAC schemes have recently been proposed that converge to collision-free schedules. In this paper we describe a ...

Adaptive, Fast, and Oblivious Convolution in Evolution Equations with Memory
To approximate convolutions which occur in evolution equations with memory terms, a variable-stepsize algorithm is presented for which advancing N steps requires only O(N log N) op...

Loop detection in term rewriting using the eliminating unfoldings
In this paper, we present a fully automatizable approach to detecting loops in standard term rewriting. Our method is based on semi-unification and an unfolding operation which pr...
