As the number of systems which offer annotations on digital documents increases, robust anchoring of annotations is a key challenge. It is especially important if the annotator lacks write-access to the document being annotated. For example, if someone makes an annotation on a web page today and the web page changes tomorrow, what happens to the annotation? One approach is simply to “orphan” th...

In keyword auctions, advertisers bid for keywords. Currently, bids and allocations are made on a per keyword basis. We show that this mechanism is neither efficient nor truthful under demand or budget constraints and provide a truthful efficient (quasi) polynomial mechanism for allocating keywords under budget constraints. As a side effect our proposed mechanism has higher revenue than the curr...

In nuclear fission, a delayed neutron is a neutron emitted by one of the fission products any time from a few milliseconds to a few minutes after the fission event. The counts of delayed neutrons constitute a time series sequence. The analysis of such time series can prove to be very significant for purpose of predictive maintenance in nuclear power plants. In this paper we aim to identify anom...
