This paper proposes a D-algebra to compose decisions from multiple access control policies. Compared to other algebrabased approaches aimed at policy composition, D-algebra is the...
We present the key ideas in the design and implementation of Beaver, an SMT solver for quantifier-free finite-precision bit-vector logic (QF BV). Beaver uses an eager approach, enc...
The search for frequent subgraphs is becoming increasingly important in many application areas including Web mining and bioinformatics. Any use of graph structures in mining, howev...
In this paper we elucidate the patterns of behavior of home movie makers through a study of 12 families and a separate focus group of 7 teenagers. Analogous to a similar study of ...

As graph models are applied to more widely varying fields, researchers struggle with tools for exploring and analyzing these structures. We describe GUESS, a novel system for grap...
