Reconstructing Events
When something happens today, anywhere in the world, it will probably be captured on camera. Very likely, it will be captured by many cameras. Increasingly, it will be captured from many perspectives—by security cameras, overhead cameras, mobile users, and social media, as Figure 1 illustrates. This shift toward constant, multiperspective imaging will have a profound influence on how we chronic...
متن کاملReconstructing Provenance
Provenance is an increasingly important aspect of data management that is often underestimated and neglected by practitioners. In our work, we target the problem of reconstructing provenance of files in a shared folder setting, assuming that only standard filesystem metadata are available. We propose a content-based approach that is able to reconstruct provenance automatically, leveraging sever...
متن کاملReconstructing sequences
We prove that every sequence of length n can be reconstructed from the multiset of all its subsequences of length k, provided k ≥ (1 + o(1)) √ n logn. This is a substantial improvement on previous bounds.
متن کاملReconstructing compositions
We consider the problem of reconstructing compositions of an integer from their subcompositions, which was raised by Raykova (albeit disguised as a question about layered permutations). We show that every composition w of n ≥ 3k+1 can be reconstructed from its set of k-deletions, i.e., the set of all compositions of n− k contained in w. As there are compositions of 3k with the same set of k-del...

The first two chapters are new, the first biographical in character, and the second a new translation and commentary of the Hippocratic Oath. Temkin lived long enough to become his o...
