Memory-Limited Execution of Windowed Stream Joins
We address the problem of computing approximate answers to continuous sliding-window joins over data streams when the available memory may be insufficient to keep the entire join...

Optimal structure of memory models for lossless compression of binary image contours
In this paper we study various chain codes, which are representations of binary image contours, in terms of their ability to compress in the best way the contour information using...

MAC Precomputation with Applications to Secure Memory
We present ShMAC (Shallow MAC), a fixed input length message authentication code that performs most of the computation prior to the availability of the message. Specifically, Sh...
