Virtual museums – not so far away
As more science and natural history museums move away from the tired ‘stuffed animals and fossils’ format towards interactive exhibits, some are also offering dynamic cyber visits. Now, there’s no need to leave your desk to examine fossils in three dimensions or check out Galileo’s body parts. The first stop on an online museum tour should be the San Francisco Exploratorium, where there’s an ex...
متن کاملA short proof that shuffle squares are 7-avoidable
A shuffle square is a word that can be partitioned into two identical words. We obtain a short proof that there exist exponentially many words over the 7 letter alphabet containing no shuffle square as a factor. The method is a generalization of the so-called power series method using ideas of the entropy compression method as developped by Gonçalves, Montassier, and Pinlou. 1991 Mathematics Su...

متن کاملOptimal IR: How Far Away?
There exists a gap between what a human user wants in mind and what (s)he could get from the information retrieval (IR) systems by his/her queries. We say an IR system is perfect if it could always provide the users with what they want in their minds if available in corpus, and optimal if it could present to the users what it finds in an optimal way. In this paper, we empirically study how far ...
متن کاملSo near, and yet so far: Managing 'far-away' interferers in dense femto-cell networks
We expect femto-cells to be massively and densely deployed in the future. Numerous existing works on femto-cell interference management assume that the local topology of interfering femto-cells can be sufficiently approximated through sensing, if not already known in advance. We show that this assumption results in poor throughput performance in dense femto-cell networks. For some cell-edge use...
