Continuous-Time Average-Preserving Opinion Dynamics with Opinion-Dependent Communications
We study a simple continuous-time multiagent system related to Krause's model of opinion dynamics: each agent holds a real value, and this value is continuously attracted by e...

Velocity-dependent dynamic curvature gain for redirected walking
—Redirected walking (RDW) techniques allow people to walk in a larger virtual space than the physical extents of the laboratory. We describe two experiments conducted to investig...

On the Security of Dynamic Group Signatures: Preventing Signature Hijacking
We identify a potential weakness in the standard security model for dynamic group signatures which appears to have been overlooked previously. More specifically, we highlight tha...

An Optimal Dynamic Data Structure for Stabbing-Semigroup Queries
Let S be a set of n intervals in R, and let (S, +) be any commutative semigroup. We assign a weight ω(s) ∈ S to each interval in S. For a point x ∈ R, let S(x) ⊆ S be the se...
