In this paper, we discuss Bitfrost, the security model developed by the One Laptop Per Child project for its XO laptop computers. Bitfrost implements a number of security measures...
We consider semidefinite programming relaxations of the quadratic assignment problem, and show how to exploit group symmetry in the problem data. Thus we are able to compute the b...
The Semi-Public Displays project utilizes public displays to assist in the interactions of small groups. This paper describes a set of visualizations for presence information of g...
Computing frequent itemsets is one of the most prominent problems in data mining. We introduce a new, related problem, called FREQSAT: given some itemset-interval pairs, does ther...
The recent explosion in shared media content and sensed data produced by mobile end-users is challenging well-established principles and assumptions in data trust models. A fundam...
