Efficient Secure Linear Algebra in the Presence of Covert or Computationally Unbounded Adversaries
In this work we study the design of secure protocols for linear algebra problems. All current solutions to the problem are either inefficient in terms of communication complexity o...

Fast Computation of Smallest Enclosing Circle with Center on a Query Line Segment
Here we propose an efficient algorithm for computing the smallest enclosing circle whose center is constrained to lie on a query line segment. Our algorithm preprocesses a given s...

Computing Preferred Extensions for Argumentation Systems with Sets of Attacking Arguments
The hitherto most abstract, and hence general, argumentation system, is the one described by Dung in a paper from 1995. This framework does not allow for joint attacks on arguments...

On Uncertainty in Context-Aware Computing: Appealing to High-Level and Same-Level Context for Low-Level Context Verification
There is an inherent chasm between the real-world and the world that can be perceived by computer systems, yielding uncertainty and ambiguity in system perceived context, with cons...

Polynomial-Time Computable Backup Tables for Shortest-Path Routing
For networks employing shortest-path routing, we introduce a new recovery scheme which needs only one backup routing table. By precomputing this backup table, the network recovers...
